p. 802). As Ai, Peterson, Tice, Bolling, and Koenig (2004) observed, ‘hope seems to be more motivational and emotional, whereas optimism is more strictly attitudinal and expectational’ (p. 437). Consistent with this key conceptual distinction, hope by virtue of its agency subtrait is more closely linked than optimism to general self-efficacy ( Bryant & Cvengros, 2004 ). MEASURES REVIEWED HERE Because hope and optimism may be best conceptualized as distinct but related constructs, we review these measures separately and then discuss global and more domain-specific measures of these constructs. In each case, we review evidence supporting the reliability and construct validity of the relevant measurement instruments. Although the instruments most commonly used to assess hope and optimism in current research were origi- nally developed during the 1990s, these measurement scales continue today to dominate the field of personality, social psychology, and behavioral medicine. The persistence and popularity of these instruments in contempo- rary psychosocial research attests to the breadth and depth of their theoretical and psychometric foundations. Yet, despite the continued dominance of these basic measurement tools, researchers have also developed new measures of hope and optimism that reflect emerging conceptual advances and refinements, as well as specific applications concerning future expectations in relation to particular situational or medical conditions. Because these later developments in measurement build directly on earlier work, we begin by first reviewing the domi- nant measurement tools for assessing hope and optimism, and then cover more recent advances in assessment of these important constructs.

Within Snyder’s framework, hope is defined as ‘a cognitive set that is based on a reciprocally derived sense of successful (a) agency (goal-directed determination) and (b) path- ways (planning of ways to meet goals)’ ( Snyder et al., 1991 , p. 571). From the perspective of this two-factor frame- work, agency is a feeling of efficacy that one can work toward a goal and pathways refer to the development of plans (or ‘ways’) to achieve desired goals (see also Snyder, 1989, 1994, 1995, 2000, 2002 ). Snyder’s model thus48 3. MEASURES OF HOPE AND OPTIMISM II. EMOTIONAL DISPOSITIONS
conceptualizes hope as a cognitive construct. This comprises individuals’ ability to work to personally important goals ( Snyder, 1994; Snyder, Rand, & Sigmon 2002; Weis & Speridakos, 2012 ). To assess hope, Snyder et al. (1991) constructed the Adult Hope Scale (AHS), consisting of four statements designed to reflect agency, four statements designed to reflect pathways, and four unscored ‘filler’ items, with which respondents indicate their extent of agreement. The reliability and validity of the SHS is backed by much research. In addition, the SHS is associated with multiple meaningful psychological and physical variables. A large body of evidence supports the reliability and validity of the SHS as a measure of dispositional hope, and connects hope to a host of meaningful psychological and physical variables (see Snyder, 2002 ;Snyder et al., 2001). Indeed, some suggest the SHS has the most construct and external validity of any measure of hope. Empirical research supports Snyder et al.’s (1991) bidimensional model of hope. Factor analyses of the SHS have revealed two distinct factors reflecting agency and pathways that are positively correlated, with the typical magnitude of correlation being about .40 ( Snyder et al., 2001 ). Consistent with the notion of correlated factors, confirmatory factor analyses have shown that responses to the SHS are accurately represented in terms of an overarching higher-order hope construct defined by the agency and pathways subtraits ( Babyak, Snyder, & Yoshinoba 1993; Bryant & Cvengros, 2004; Rand, 2009 ). Thus, researchers often use SHS total score as a unitary measure of hope (e.g., Snyder et al., 1991 ). Another body of research on the construct of hope is that of Dufault and Martocchio (1985) , as constructed by Herth (1991) in the field of nursing research. They define hope as ‘a multidimensional dynamic life force charac- terized by a confident yet uncertain expectation of achieving a future good which is realistically possible and personally significant’ ( Dufault & Martocchio, 1985 , p. 380). Hope is assumed to include two spheres /C0generalized hope, ‘an intangible umbrella that protects hoping persons by casting a positive glow on life’ ( Dufault & Martocchio, 1985 , p. 380), and particularized hope, which concerns a specific outcome or hope object /C0which include affective, behavioral, cognitive, affiliative, temporal, and contextual components. To operationalize the constructs in Dufault and Martocchio’s (1985) model, Herth (1991) constructed the Herth Hope Scale (HHS), consisting of 30 statements designed to tap three factors: Temporality and Future (the perceived likelihood of attaining the desired outcome), Positive Readiness and Expectancy (feelings of confidence), and Interconnectedness (the awareness of interdependence between self and others). With the HHS, respondents indi- cate degree of agreement with each statement. Despite the underlying multidimensional model, researchers often treat the HHS as measuring a single global construct. Although there are other existing models of hope, including those of Beck (1993) ,Nunn and colleagues (1996) ,Hinds (1984) ,Nowotny (1989) ,Post-White, Ceronsky, and Kreitzer (1996) , and Staats and Stassen (1985) , the conceptual models underlying Snyder et al.’s (1991) and Herth’s (1991) instruments have been used most often in the empirical literature. More recently, interest has shifted toward the development of context-dependent measures /C0like the Snyder State Hope Scale ( Snyder et al., 1996 ) and the Work Hope Scale (Juntunen & Wettersten, 2006) to assess more transitory states of hope. Optimism, in comparison, reflects a generalized positive expectancy for future outcomes. Although numerous models of optimism have been developed (e.g., Chang, 2001 ;Colligan, Offord, Malinchoc, Schulman, & Seligman 1994;Dember, Martin, Hummer, Howe, & Melton 1989 ;Gillham, 2000 ;Levy, 1985 ;Malinchoc, Offord, & Colligan 1995), the most dominant theoretical orientation has undoubtedly been Scheier and Carver’s (1985) . In their origi- nal conceptualization, Scheier and Carver (1985) defined optimism as a stable predisposition to ‘believe that good rather than bad things will happen’ (p. 219). Thus, as opposed to hope, optimism was originally conceptualized as a unitary trait representing a bipolar continuum, with optimism and pessimism. To assess dispositional optimism, Scheier and Carver (1985) constructed the Life Orientation Test (LOT) con- sisting of four statements designed to reflect optimism, four statements designed to reflect pessimism, and four unscored ‘filler’ items, with which respondents indicate their extent of agreement. A large body of evidence sup- ports the reliability and validity of the LOT as a measure of dispositional optimism, and connects optimism to a variety of important psychological and physical outcomes (see Scheier & Carver, 1992 ). Although early critics (e.g., Smith, Pope, Rhodewalt, & Poulton 1989 ) argued that the LOT is better conceived as a measure of neuroti- cism rather than optimism, later evidence has supported the discriminant validity of the LOT as distinct from general negative affectivity (e.g., Bryant & Baxter, 1997 ;Mroczek, Sprio, Aldwin, Ozer, & Bosse 1993 ;Scheier et al., 1994 ). Indeed, far more evidence supports the construct validity and cross-sample generalizability of the LOT than exists for any other existing measure of optimism. Subsequent conceptual and empirical work led to the refinement of the original LOT. In particular, Scheier et al. (1994) identified two LOT items that seem explicitly to reflect positive reinterpretation as a coping strategy, rather than the expectation of positive outcomes per se. Because including these two problematic items in the LOT might inflate the relationship between optimism and positive reinterpretation ( Affleck & Tennen, 1996 ),49 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
Scheier et al. (1994) proposed a ‘minor modification’ (p. 1063) of the LOT, in which these two items and one pes- simism item (‘Things never work out the way I want them to’) are omitted, and a new optimism item (‘Overall, I expect more good things to happen to me than bad’) is added, yielding three items assessing optimism and three items assessing pessimism. Supporting the use of this revised instrument, which is known as the LOT-R, Scheier et al. (1994) reported relatively stable test /C0retest reliability and further suggested that the original and revised versions of the instrument are essentially comparable, based on high correlations (‘in the .90s,’ p. 1073) between total scores on the LOT and LOT-R. Although Scheier and Carver (1985) originally conceptualized optimism as a global unidimensional trait, other research indicates that dispositional optimism consists of two separate, but negatively correlated, subtraits reflect- ing positively-framed optimism and negatively-framed pessimism. To explain discrepancies in outcome expec- tancies within individuals, for instance, Dember et al. (1989) suggested optimism was bidimensional, consisting of dispositional levels of both optimism and pessimism. According to Dember and colleagues (1989) , rejection of pessimism is not equivalent to the endorsement of optimism; nor is the rejection of optimism equivalent to the endorsement of pessimism. Empirical research suggests this two-factor model is preferable to a one-factor model, although researchers disagree as to the extent of the correlation between optimism and pessimism. Using confirmatory factor analysis to investigate the responses of 389 college students to the LOT, for example, Chang, D’Zurilla, and Maydeu-Olivares (1994) found that a model consisting of correlated dimensions of opti- mism and pessimism ( r52.54) fit better than did a one-factor ‘total score’ model. Indeed, Scheier and Carver’s (1985) factor analyses of their own LOT data revealed two correlated ( r52.64) factors, Optimism and Pessimism, which together fit their data significantly better than a one-factor model. In addition, Bryant and Cvenrgos (2004) found that a two-factor model with correlated dimensions of Optimism and Pessimism (r52.63) explained the responses of 351 college students to the LOT better than did a one-factor model. Additional research with children ( Fischer & Leitenberg, 1986 ), college students ( Bailey, Eng, Frisch, & Snyder 2007), and older adults ( Mroczek et al., 1993; Robinson-Whelen, Kim, MacCallum, & Kiecolt-Glaser 1997 ) sup- ports a bidimensional, as opposed to unidimensional, model of dispositional optimism. There is also evidence to support the discriminant validity of this bidimensional structure in predicting mood ( Marshall, Wortman, Kusulas, Hervig, & Vickers 1992 ) and physical health ( Robinson-Whelen et al., 1997 ). Several researchers have directly examined the discriminant validity of hope and optimism as assessed by the SHS and the LOT, respectively. For example, evidence indicates that optimism is more influential on the use of positive reappraisal as a coping strategy than does hope, whereas hope has a stronger influence on level of gen- eral self-efficacy than does optimism ( Bryant & Cvengros, 2004 ). Other work has found that hope uniquely influ- ences college students’ grade expectancies, whereas optimism does not ( Rand, 2009 ); and that hope is a stronger predictor of life satisfaction than is optimism ( Bailey et al., 2007 ). Moreover, hope and optimism each demon- strate unique effects in predicting measures of life quality, including mastery, purpose in life, self-acceptance, social integration, positive affect, and life satisfaction ( Gallagher & Lopez, 2009 ), as well as positive mental and physical health ( Magaletta & Oliver, 1999 ) and level of depression in reaction to traumatic brain injury ( Peleg et al., 2009 ). Comparing the psychometric properties of measures of hope and optimism /C0the Revised Generalized Expectancy for Success Scale (Hale et al., 1994), the LOT-R, the Hope Scale, and the Hunter Opinions and Personal Expectations Scale ( Nunn et al., 1996 )/C0Steed (2002) concluded that ‘the LOT and HS are the scales of choice when assessing hope and/or optimism’ (p. 446). Just as with hope, however, more recent additions to the optimism measurement literature has focused on context. For example, the Cancer Patient Optimism Scale (Radwin et al., 2005) and the HIV Treatment Optimism Scale (Van de Ven et al., 2000) have extended general principles of the LOT-R to assess optimism in specific populations. Below, we describe and evaluate several important measures of hope and optimism. Adult Hope Scale (AHS): Children’s Hope Scale (CHS) (Snyder et al., 1991). Variable Snyder et al. (1991) defined hope as ‘a cognitive set that is based on a reciprocally derived sense of successful (a) agency (goal-directed determination) and (b) pathways (planning of ways to meet goals)’ (p. 571).50 3. MEASURES OF HOPE AND OPTIMISM II. EMOTIONAL DISPOSITIONS
Description The original SHS consisted of 12 statements to which respondents indicate their degree of agreement. Eight items contain hope-related statements and four are fillers. In line with their definition of hope, the AHS contains four items that assess agency and four items that assess pathways. The four filler items reflect other, non-hope related constructs. Item response format is on a four point scale from 1 definitely false to 4 definitely true and total hope scores can range from eight to 32 (Snyder et al., 1991). The AHS has also been normed for use with children (also the Children’s Hope Scale (CHS) contains six hope statements reworded to be more understandable for children with a six point Likert-type response scale from 1 none of the time to 6 all of the time and total scores can range from six to 36) (Snyder et al., 1997). Sample The original SHS was validated with six separate samples ( N54126) composed of both introductory psychol- ogy students and two clinical samples. The overall mean hope scores ranged from 22.60 ( SD54.35) to 25.64 (SD52.93) with an overall average of 24.70 ( SD53.33). Although males and females did not significantly differ in hope scores, those in the clinical samples reported lower overall hope than those in the college samples (Snyder et al., 1991). The CHS was validated with a sample of children aged 9 to 14 years ( N5372). Mean hope scores were similar at pretest ( M525.41, SD54.99) and posttest ( M527.03, SD54.51) (Snyder et al., 1997). Reliability Internal Consistency Cronbach alpha coefficients reported for the original measure range from .74 to .84 among the eight sample groups (mean 5.77) (Snyder et al., 1991). Alpha coefficients for the Children’s Hope Scale range from .74 to .81 (Snyder et al., 1997). Test/C0Retest Test/C0retest reliability for the original measure is acceptable at three weeks ( r5.85), eight weeks ( r5.73), and 10 weeks ( r5.76;r5.82) (Snyder et al., 1991). Test /C0retest reliability for the children’s measure at one month was r5.71 (Snyder et al., 1997). A recent meta-analysis ( Hellman, Pittman, & Munoz 2013 ) of the past two decades of research using the SNH reported strong test /C0retest reliability coefficients that did not vary significantly across different types of samples. Validity Convergent/Concurrent SHS scores correlate positively with measures of optimism (Life Orientation Test r5.60; General Expectancies for Success Scale r5.55), control (Burger /C0Cooper Life Experiences Survey r5.54; Problem Solving Inventory r5.62), esteem (Rosenberg Self-esteem Scale r5.53) (Snyder et al., 1991). Also CHS scores correlate positively with children’s assessment of competencies in scholastics ( r5.59), social acceptance ( r5.43), athletics ( r5.34), physical appearance ( r5.46), and behavioral conduct ( r5.41) (Snyder et al. 1997). Divergent/Discriminant SHS scores correlate negatively with measures of hopelessness and depression (Beck Hopelessness Scale r52.51; Beck Depression Inventory r52.42) and general measures of psychological problems (MMPI rs52.30 to 2.60) (Snyder et al., 1991). SHS scores do not correlate with the unrelated Self-Consciousness Scale ( rs5.06,2.03). Also, CHS scores do not correlate with intelligence ( r5.03) (Snyder et al., 1997). Construct/Factor Analytic For the CHS, a principal components analysis with varimax rotation yielded a two-dimensional solution accounting for approximately 58% of the total variance in line with Snyder and colleagues’ (1997) two- dimensional definition of hope (agency and pathways). Criterion/Predictive SHS scores are predictive of high school ( r5.17) and college GPA ( r5.13) as well as expected grades ( r5.32) and number of goals held by participants ( r5.24) (Snyder et al., 1991). CHS scores correlate positively with Iowa Test of Basic Skills percentile scores ( r5.50) (Snyder et al., 1997).51 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS

Results and Comments As the SHS is intended to assess the agency and pathways to success domains of hope, it is especially suited to assess positive achievement cognitions. However, this measure does not seem to assess overall positive feel-ings for the future and as such, might be better utilized as a cognitive measures of confidence in personal abilityor efficacy.

Herth Hope Scale (HHS): Herth Hope Index (HHI) (Herth, 1991, 1992 ). Variable The HHS and HHI were based on the Dufault and Martocchio (1985) definition of hope as ‘a dynamic life force characterized by a confident yet uncertain expectation of achieving good, which, to the hoping person, is realistically possible and personality significant’ (p. 380). Description The original HHS consisted of 30 statements to which respondents indicate their degree of agreement. Ten items contain statements of temporality and future, ten items contain statements of positive readiness and expec- tancy, and ten items contain statements of interconnectedness. Item response format is on a four-point scale from 0 never applies to 3 applies and total hope scores can range from 0 to 90 ( Herth, 1991 ). The HHI is an abbreviated form (12-item) of the HHS used in clinical settings. Item response format is on a four point scale from 1 strongly disagree to 4 strongly agree and total scores can range from 12 to 48 ( Herth, 1992 ). The HHS has also been translated into a Spanish-language version ( Arnau, Martinez, Guzman, Herth, & Konishi 2010 ). Sample The original HHS was validated with a sample of well adults ( N5185), a sample of elderly in the community (N540), and a sample of bereaved elderly ( N5300). Hope scores for the well adults was relatively high ( M580, range 60-90), slightly lower among elderly in the community ( M572,SD56.31), and lowest among bereaved elderly ( M554,SD55.60) ( Herth, 1991 ). The HHI was validated with a sample of varyingly ill patients (N5172). Average scores fell slightly above the scale midpoint ( M532.39, SD59.61) ( Herth, 1992 ). The Spanish HHS was validated with a sample of 315 Latino students ( Arnau et al., 2010 ).53 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
Reliability Internal Consistency Cronbach alpha coefficients reported for the origi nal HHS were .94 for the elderly and .95 for bereaved elderly ( Herth, 1991 ). Similarly, the alpha coefficient for the HHI overall was .97, as well as .96 for adults with chronic illnesses, .94 for adults with acute illnesses and .98 for adults with terminal illness (Herth, 1992 ). Test/C0Retest Test/C0retest reliability for the original measure was reported at three weeks among healthy adults ( r5.90), elderly ( r5.89), and bereaved elderly ( r5.91) ( Herth, 1991 ). Test/C0retest reliability for the HHI was reported at two weeks ( r5.91) ( Herth, 1992 ). Validity Convergent/Concurrent The HHI was positively correlated with the HSS ( r5.92), spiritual well-being ( r5.84), and the Nowotny Hope Scale ( r5.81) ( Herth, 1992 ). Divergent/Discriminant HSS scores correlate negatively with depression (Beck Hopelessness Scale) among healthy adults ( r52.74) and the elderly ( r52.69) ( Herth, 1991 ). Construct/Factor Analytic Factor analysis using combined data ( N5300) supported the three-factor structure (temporality and future, positive readiness and expectancy, and interconnectedness) of the HHS among the bereaved elderly sample (Herth, 1991 ). A separate maximum-likelihood factor analysis with varimax rotation supported the three-factor HHI structure ( Herth, 1992 ). Criterion/Predictive HHS scores positively predict coping response ( r5.80) ( Herth, 1991 ). No criterion/predictive data are currently available for the HHI.

Beck Hopelessness Scale (BHS) (Beck, 1993 ). Variable Beck et al. (1993) defined hopelessness as a lack of hope and optimism; a system of negative expectancies con- cerning one’s self and future circumstances.55 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
Description The BHS consists of 20 statements to which respondents indicate whether or not that statement is true or false. Of these, nine items are keyed false and 11 are keyed true. Possible total scores range from 0 to 20 with higher scores suggesting higher levels of hopelessness ( Beck, 1993 ). Sample The BHS was validated with a clinical sample ( N5294) recently hospitalized for suicide attempts ( Beck, 1993 ). Reliability Internal Consistency A Cronbach alpha coefficient was reported (.93) and item-scale correlations ranged from.36 to .76 ( Beck, 1993 ). Test/C0Retest No test /C0retest reliability evidence is currently available for the BHS. Validity Convergent/Concurrent BHS scores correlate positively with pessimism (Stuart Future Test) ( r5.60) and depression (Beck Depression Inventory) ( r5.63) ( Beck, 1993 ). Divergent/Discriminant No divergent validity evidence is currently available for the BHS. Construct/Factor Analytic A principal components analysis with varimax rotation suggested three BHS dimensions (relating to: feelings about the future, loss of motivation, and future expectations) ( Beck, 1993 ). Criterion/Predictive BHS scores are predictive of clinician-rated measures of hopelessness ( r5.74) and attempted suicide rate (r5.62). Location Beck, A.T. (1993). Beck Hopelessness Scale (BHS). San Antonio, TX: Psychological Corporation. Results and Comments The BHS is a classic measure for good reason. It is highly reliable and versatile given the generality of its items. This scale is especially well-suited for clinical populations but commonly used with general adult samples as well. As such, the BHS has been utilized in the validation of almost all other measures of hope and optimism.

Hunter Opinions and Personal Expectancies Scale (HOPES) (Nunn et al., 1996 ). Variable Nunn et al. (1996) defined hope as, ‘that construction of, and response to, the perceived future, in which the desirable is subjectively assessed to be probable’ (p. 532). Accordingly, hope has three domains including tempo- rality (e.g., future oriented), desirability (desirable outcome), and expectancy (probability of that outcome occurring). Description HOPES consists of 20 statements to which respondents indicate their degree of agreement. Ten of these items reflect the hope subscale and 10 reflect the despair subscale. Item response-format is on a five-point scale from 0 ‘describes me not at all’ to 4 ‘describes me extremely well,’ and total scores can range from 0 to 80 (hope score 5 hope subscale minus despair subscale plus 40). Sample The HOPES was developed using three separate samples ( N5307) including a medical school sample (N5211), an adolescent male sample ( N52157), a hospital staff sample ( N5318), and a post-earthquake com- munity sample ( N51089). Overall mean hope scores were high ( M558.72, SD510.89). Reliability Internal Consistency Cronbach alpha coefficients for each sample have been reported ( αs5.80 to .92) ( Nunn et al., 1996 ). Test/C0Retest A stability coefficient (r 5.71) after 15 months has been reported ( Nunn et al., 1996 ). Validity Convergent/Concurrent HOPES scores correlate positively with a measure of extraversion ( r5.39) ( Nunn et al., 1996 ). Discriminant Validity HOPES scores correlate negatively with trait anxiety ( r52.64), neuroticism ( r52.46), locus of control (r52.46), and depression (Beck Depression Scale) ( rs52.51 to2.67) ( Nunn et al., 1996 ). Construct/Factor Analytic A principal components analysis yielded five dimensions when combining the HOPES with EPI neuroticism, Spielberger’s Trait Anxiety Scale, Beck Depression Scale, and Rotter’s Locus of Control Scale, suggesting the uniqueness of the HOPES instrument ( Nunn et al., 1996 ). Criterion/Predictive Individuals with the lowest HOPES scores also exhibit lower general health scores than those with the highest HOPES scores. Similarly, individuals with the lowest HOPES scores are affected more by catastrophic events (e.g., earthquakes) than those with the highest HOPES scores ( Nunn et al., 1996 ). Location Nunn K.P., Lewin T.J., Walton J.M., & Carr V.J. (1996). The construction and characteristics of an instrument to measure personal hopefulness. Psychological Medicine, 26 , 531/C0545. Results and Comments Of all the measures of hope reviewed, the HOPES was validated in a uniquely iterative process and as such, is perhaps the most thoroughly developed of the hope scales. HOPES is also unique in that is was validated with a wide range of sample populations, making it extremely versatile.57 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS

(2010) defined hope as a ‘ ...concept include[ing] a reality reference, in that the desired out- comes or goals are subjectively perceived as being possible, and it allows for hope to arise both from a negative as well as a positive starting point, i.e. as a desire for the improvement of an undesirable or an already satisfac- tory situation’ (p. 418). Description The IHS is an integration of the Miller Hope Scale, the HHI, and the SHS discussed above. Originally consist- ing of 60 items, the IHS was reduced to 23 items using factor analysis. In line with its composite scales, the IHS contains items reflecting trust and confidence, lack of perspective, positive future orientation, and social relations and personal values. Item response format is on a six point Likert-type forced-choice scale ranging from 1 ‘strongly disagree’ to 6 ‘strongly agree’ (total scores range from 23 to 138) ( Schrank et al., 2010 ). Sample The IHS was validated with a sample ( N5489) from the Austrian general population. The overall mean hope score was 93.78 ( SD512.83) (trust and confidence subdomain M527.81, SD54.03), (lack of perspective subdo- main M515.10, SD55.39), (positive future orientation subdomain M520.01, SD52.90), (social relations and personal value subdomain M519.06, SD53.33) ( Schrank et al., 2010 ). Reliability Internal Consistency The Cronbach alpha coefficient reported was .92. Subscale alpha coefficients were also high (trust and confi- dence alpha of .85; lack of perspective alpha of .85; positive future orientation alpha of .80) ( Schrank et al., 2010 ). Validity Convergent/Concurrent IHS scores correlate positively with the SHS ( rs5.62 to .39), the HHI ( rs5.81 to .64), and the MHS ( rs5.92 to .73) ( Schrank et al., 2010 ). Divergent/Discriminant IHS scores correlate negatively with a measure of depression ( r52.68). ( Schrank et al., 2010 ).58 3. MEASURES OF HOPE AND OPTIMISM II. EMOTIONAL DISPOSITIONS
Construct/Factor Analytic Principle axis factor analysis using oblique rotation ( N5484) was used to assess the factor structure of the IHS. The four-factor solution (labeled: trust and confidence, lack of perspective, positive future orientation, and social relations and personal values) suggested in the definition of hope was supported ( Schrank et al., 2010 ). Criterion/Predictive IHS scores positively predict future quality of life ( r5.56). ( Schrank et al., 2010 ). Location Schrank, B., Woppmann Mag, A., Sibitz, I., & Lauber, C (2010). Development and validation of an integrative scale to assess hope. Health Expectations, 14, 417/C0428. Results and Comments The IHS provides an excellent alternative to any of its composite measures. Those interested in harnessing the power of the SHS, the HHI, and the Miller Hope Scale will find the IHS both ‘user friendly’ and psychometrically sound. Schrank et al. (2010) noted that: ‘All three pre-existing scales have been used in research in a variety of fields and among healthy as well as diseased populations. Hence, the new scale, being based on these instruments, can be assumed to be equally applicable in healthy as well as ill people while at the same time having the advantage of most comprehensively covering the concept of hope, being concise, and psychometrically robust according to our preliminary validation’ (p. 426). INTEGRATIVE HOPE SCALE Please indicate the extent to which you agree or disagree with the following statements from 1, strongly disagree, to 6, strongly agree. 1.I have deep inner strength. 2.I believe that each day has potential. 3.I have a sense of direction. 4.Even when others get discouraged, I know I can find a way to solve the problem. 5.I feel my life has value and worth. 6.I can see possibilities in the midst of difficulties. 7.My past experiences have prepared me well for my future. 8.I’ve been pretty successful in life. 9.I have a faith that gives me comfort. 10.It is hard for me to keep up my interest in activities I used to enjoy. 11.It seems as though all my support has been withdrawn.12.I am bothered by troubles that prevent my planning for the future. 13.I am hopeless about some parts of my life. 14.I feel trapped, pinned down. 15.I find myself becoming uninvolved with most things in life. 16.There are things I want to do in life. 17.I look forward to doing things I enjoy. 18.I make plans for my own future. 19.I intend to make the most of life 20.I feel loved. 21.I have someone who shares my concerns. 22.I am needed by others. 23.I am valued for what I am.

Snyder State Hope Scale (SSHS) (Snyder et al., 1996 ). Variable Snyder et al. (1996) defined state hope as a temporally varying type of goal-directed thinking reflecting feel- ings of optimism toward the future.59 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
Description The SSHS consists of six statements to which respondents indicate their degree of agreement. In line with the dis- positional focus, the SSHS contains items assessing agency (goal-directly determination) and pathways (planning of ways to meet goals) simply reworded to reflect the immediate situation. Item response format is an 8-point scale ranging from 1 definitely false to 8 definitely true and total scores can range from zero to 48 ( Snyder et al., 1996 ). Sample The SSHS was validated with a sample ( N5444) composed of introductory psychology students over the course of 30 days. The overall mean hope scores were similar for men ( M537.24) and women ( M537.06) with an overall average of 37.15 ( SD56.33) ( Snyder et al., 1996 ). Reliability Internal Consistency Cronbach alpha coefficients range from .82 to .95 (median α5.93) ( Snyder et al., 1996 ). Test/C0Retest Test/C0retest reliability for the original measure has been reported at three weeks ( r5.85), eight weeks ( r5.73), and 10 weeks ( r5.76;r5.82) ( Snyder et al., 1996 ). Validity Convergent/Concurrent SSHS scores correlate positively with dispositional optimism (SHS r5.79) and high dispositional hope is pre- dictive of high state hope on a daily basis. State hope scores also correlate with state self-esteem ( r5.68) and state positive affect ( r5.65). State Hope Scale scores also correlate with a daily report of their evaluations of that day (r5.51) ( Snyder et al., 1996 ). Divergent/Discriminant SSHS scores correlate inversely with state negative affect ( r52.47) ( Snyder et al., 1996 ). Construct/Factor Analytic A principal components analysis with oblique rotation yielded a two-component solution in line with Snyder and colleagues’ (1996) two-dimensional definition of hope (agency and pathways), respectively. Criterion/Predictive SHS scores are predictive of the number of correct responses on a complex verbal learning task ( r5.27) (Snyder et al., 1996 ). Location Snyder, C.R., Sympson, S.C., Ybasco, F.C., Borders, T.F., Babyak, M.A., & Higgins, R.L. (1996). Development and validation of the State Hope Scale. Journal of Personality and Social Psychology, 70 , 321/C0335. Results and Comments The SSHS assesses agency and pathways to success in the moment. As such, it is a valuable alternative to mea- suring dispositional hope and especially well-suited to assess cognitions that one can achieve a goal in the moment. It is also brief and potentially limited in its ability to assess how individuals feel if faced with multiple problems at the same time, for example. SSHS-LIKE ITEMS Directions: Read each item carefully. Using the scale shown below, please select the number that best describes how you think about yourself right now and put that number in the blank provided. Please take afew moments to focus on yourself and what is going on in your life at this moment. Once you have this ‘here and now’ set, go ahead and answer each item according to the following scale: 1 5Definitely False;60 3. MEASURES OF HOPE AND OPTIMISM II. EMOTIONAL DISPOSITIONS
25Mostly False; 3 5Somewhat False; 4 5Slightly False; 55Slightly True; 6 5Somewhat True; 7 5Mostly True; 85Definitely True. ____1. I can get myself out of problems. ____2.

I feel like I am doing a good job right now of doing what I set out to do.Notes : When administering the measure, it is labeled the Goals Scale. The even-numbered items are agency, andthe odd-numbered items are pathways. Subscale scoresfor agency or pathways are derived by adding the threeeven- and odd-numbered items, and the total StateHope Scale score is the sum of all six items.Copyright r1996 American Psychological Association.

Work Hope Scale (WHS) (Juntenen & Wettersten, 2006). Variable Juntenen and Wettersten (2006) relied heavily on the Snyder and colleagues’ (1991) conceptualization of hope as goals, pathways to achieve those goals, and motivation or agency to achieve those goals. Since their scalefocuses on occupational hope, Juntenen and Wettersten (2006) focused on work-related goals, pathways, andagency. Description The WHS consists of 24 statements to which respondents indicate their degree of agreement. In line with the SSHS, the WHS contains items assessing goals, pathways, and agency. Item response format is on a 7-point Likert-type scale ranging from 1 ‘strongly disagree’ to 7 ‘strongly agree’ and total scores ranging from 24 to 168 (Juntunen & Wettersten, 2006). Sample The WHS was validated with a sample ( N5224) composed of introductory psychology students, a community sample, and a sample of low income women. The overall mean hope scores was 132.09 ( SD522.10) (Juntunen & Wettersten, 2006). Reliability Internal Consistency A Cronbach alpha coefficient was found to be .90 (Juntunen & Wettersten, 2006). Test/C0Retest Test/C0retest reliability for the WHS was reported after two weeks ( r5.90) (Juntunen & Wettersten, 2006). Validity Convergent/Concurrent WHS scores correlate positively with measures of vocational identity ( r5.65), career-decision self-efficacy (r5.75), agency ( r5.95), pathway ( r5.93), and goals ( r5.95) hope subscales (Juntunen & Wettersten, 2006). WHS scores correlate positively with a measure of optimism (LOT-R r 5.53), significantly lower than the correla- tions between WHS scores and vocational identity. Divergent/Discriminant No divergent/discriminant evidence is currently available for the WHS.61 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
Construct/Factor Analytic A confirmatory factor analysis as well as an exploratory factor analysis using maximum-likelihood, with obli- que rotation suggested that the three-factor model was not optimal. Rather, the WHS is better conceptulaized as a one-factor model (Juntunen & Wettersten (2006). Criterion/Predictive WHS scores are significantly lower among the economically disadvantaged and recipients of welfare as com- pared with those who attend or have attended college (Juntunen & Wettersten, 2006). Location Juntunen, C.L., & Wettersten, K.B. (2006). Work hope: Development and initial validation of a measure. Journal of Counseling Psychology, 53 ,9 4/C0106. Results and Comments Hope in specific domains, with the exception of clinical populations, has been neglected until recent years. The WHS is especially worthwhile because it acknowledges that hope in general (and in clinical populations) may be different than hope experienced in specific domains like the workplace. As such, the WHS is suited for researchers interested in work-related feelings of hope. WHS-LIKE ITEMS Directions: Please indicate the extent of your agree- ment with the following statements from 1 strongly disagree to 7 strongly agree. ____1. I have plans to succeed in my profession. ____2. I know I won’t be able to find a good job.* ____3. Success at work comes easy for me. ____4. Work is personally rewarding for me. ____5. I don’t think I have the ability to do well at my job.* ____6. I know how to find jobs that I like. ____7. My professional future looks good.____8. Things will work out well for me. ____9. I cannot find a job.* ____10. I want to work in the community in which I live. Notes : Copyright r2006 American Psychological Association.

Variable Scheier and Carver (1985) define dispositional optimism as a stable personality trait characterized by general positive expectancies. Description The original LOT consists of 12 statements to which respondents indicate their degree of agreement. Four items contain positive statements assessing dispositional optimism, four items contain negative statements asses- sing dispositional optimism, and four contain filler statements. Item response format is on a five point scale from 0 strongly disagree to 4 strongly agree. Possible scores of overall optimism range from 0 to 32. The revised LOT (LOT-R) consists of 10 items (three positive, three negative, three filler items). Two problematic coping items were removed from the original LOT. Item response format mirrors that of the original measure and total scores range from 0 to 24 ( Scheier et al., 1994 ).62 3. MEASURES OF HOPE AND OPTIMISM II. EMOTIONAL DISPOSITIONS
Sample The original LOT was validated with two separate university samples ( N5624). No differences emerged between samples and total LOT scores were similar for males ( M521.03, SD54.56) and females ( M521.41, SD55.22) ( Scheier & Carver, 1985 ). The LOT-R was validated with a university sample ( N52055). LOT-R scores were similar for males ( M514.28, SD54.33) and females ( M514.42, SD54.12) ( Scheier et al., 1994 ). Reliability Internal Consistency The Cronbach alpha coefficient reported for the original LOT was .76 and item-scale correlations were moder- ate ( rs5.37 to .56) ( Scheier & Carver, 1985 ). Similarly, the alpha coefficient reported for the LOT-R was ( α5.78), along with moderate item-scale correlations ( rs5.43 to .63) ( Scheier et al., 1994 ). Test/C0Retest Test/C0retest reliability for the original measure was .79 at four weeks (Scheier & Carver, 1994). Test /C0retest reliability for the revised measure was .68 at four weeks ( r5.68), 12 weeks ( r5.60), 24 weeks ( r5.56), and 28 weeks ( r5.79) ( Scheier et al., 1994 ). Validity Convergent/Concurrent LOT scores correlate positively with internal locus of control ( r5.34) and self-esteem ( r5.48) ( Scheier & Carver, 1985 ). LOT-R scores correlate positively with self-mastery ( r5.48) and self-esteem ( r5.50). The original and revised measures correlate strongly ( r5.95) ( Scheier et al., 1994 ). Discriminant Validity LOT scores do not correlate with private and public self-consciousness ( r52.04;r52.05) and correlate nega- tively with hopelessness ( r52.47), depression ( r52.49), perceived stress ( r52.55), alienation ( rs5217 to 2.40), social desirability ( r5.26), and social anxiety ( r52.33) ( Scheier & Carver, 1985 ). LOT-R scores correlate negatively with trait anxiety ( r52.53) and neuroticism ( rs52.36 to2.43) ( Scheier et al., 1994 ). Construct/Factor Analytic A principal components analysis as well as a confirmatory factor analysis supported a two-dimensional solu- tion for positively and negatively-worded items for the LOT ( Scheier & Carver, 1985 ). Several sets of principal components analyses yielded between 1 and 5 factors but Scheier et al. (1994) settled on a unidimensional model of optimism for the LOT-R. Criterion/Predictive LOT scores correlate negatively with being bothered by physical symptoms ( rs52.22, to .31) ( Scheier & Carver, 1985). LOT-R scores correlate negatively with number of physical symptoms ( r52.21), intensity of symptom (r52.25), mental disengagement ( r52.18), and use of drugs or alcohol ( r52.11) ( Scheier et al., 1994 ).

Journal of Personality and Social Psychology ,67, 1063/C01078. Results and Comments The LOT and LOT-R are among the most commonly used measures of optimism primarily because they assess the broadly defined construct of optimism. However, these measures primarily assess dispositional rather than state or domain-specific optimism making its appropriate use limited to optimism as a stable personality trait.63 OVERVIEW OF THE MEASURES II.

Generalized Expectancy for Success Scale (GESS-R) (Hale et al., 1992 ). Variable Fibel and Hale (1978) defined optimism as ‘the expectancy held by an individual that in most situations he/she will be able to attain desired goals’ (p. 924). Hale and colleagues (1992) further noted that optimism appears to be a stable personality trait. Description The original GESS consists of 30 statements to which respondents indicate their degree of agreement. Of these, 17 items contain statements about the likelihood of future successes and 13 contain statements about the likeli- hood of future failure, reveres scored. Item response format is on a 5-point Likert-type scale from 1 ‘highly improbable’ to 5 ‘highly probable’. Possible scores range from 30 to 150 with higher scores indicating higher optimism ( Fibel & Hale, 1978 ). The revised GESS (GESS-R) consists of 25 items answered on the same scale (Hale et al., 1992 ). Sample The original GESS was validated with three separate university samples ( N5307). No differences emerged between samples and total GESS scores were similar for males ( M5112.15, SD513.24) and females ( M5112.32, SD513.80) ( Fibel & Hale, 1978 ). The GESS-R was validated with a university sample (N 5199) and demonstrates similar descriptive statistics ( M5107.00, SD55.72) ( Hale et al., 1992 ). Reliability Internal Consistency Split-half reliability coefficients for the original measure were ( α5.91) for males and ( α5.90) for females (Fibel & Hale, 1978 ). Similarly, the split-half reliability for the revised measure was ( α5.92) ( Hale et al., 1992 ). Test/C0Retest Test/C0retest reliability for the revised measure was .69 at six weeks ( Hale et al., 1992 ). Validity Convergent/Concurrent GESS-R scores correlate positively with the LOT ( r5.40), self-esteem ( r5.46), and extraversion ( r5.16). GESS scores correlate slightly with social desirability ( r5.26) and GESS-R scores correlate slightly but non-significantly with Eysenck’s lie scale ( r5.18) ( Hale et al., 1992 ).64 3. MEASURES OF HOPE AND OPTIMISM II. EMOTIONAL DISPOSITIONS
Divergent/Discriminant GESS scores correlate negatively with measures of depression ( rs52.54 to2.69) and hopelessness ( rs52.31 to2.69) and GESS-R scores correlate negatively with introversion ( r52.23) and neuroticism ( r52.22) (Hale et al., 1992 ). Construct/Factor Analytic The original and revised measures correlate strongly ( r5.98) ( Hale et al., 1992 ). No factor analytic evidence is currently available for the GESS-R. Criterion/Predictive No criterion/predictive validity evidence is currently available for the GESS/GESS-R. Location Original 30-Item Measure Fibel, B., & Hale, W.D. (1978).

Results and Comments The GESS-R demonstrates acceptable reliability and validity and as such, has been frequently used along with the LOT/LOT-R in laboratory and field studies alike. As with the LOT/LOT-R, The GESS-R’s primary strength lies in its broad conceptualization of optimism and measures that assess the variety of domains of optimism.

Positive and Negative Expectancy Questionnaire for the Assessment of Personal Optimism and Social Optimism /C0Extended (POSO-E) (Schweizer & Koch, 2000). Variable Schweizer and Koch (2000) relied on a slightly modified version of Scheier and Carver’s (1985) definition of optimism as a personality trait construct characterized by positive expectations. They further suggested that optimism is both personal and socially-oriented. Description The POSO-E consists of 10 statements to which respondents indicate their degree of agreement. Item response- format is on a four-point scale labeled 1 ‘incorrect,’ 2 ‘partly correct,’ 3 ‘almost correct,’ and 4 ‘completely correct,’ with total scores ranging from 10 to 40 (Schweizer & Koch, 2000). Sample The POSO-E was validated with an undefined sample ( N5348). No significant differences in optimism emerged between males ( M528.47, SD54.08) and females ( M529.21, SD54.27) (overall M528.92, SD54.20) (Schweizer & Koch, 2000). Reliability Internal Consistency Cronbach alpha coefficients reported were .78 for the personal optimism subscale, .86 for the social optimism subscale, and .87 for the self-efficacy subscale (Schweizer & Koch, 2000). Test/C0Retest No test /C0retest reliability evidence is currently available for the POSO-E. Validity Convergent/Concurrent All POSO-E optimism subscales correlate positively with life satisfaction ( rs5.28 to .75) and negatively with impulsiveness ( rs52.26 to 2.42), somatic complaints ( rs52.19 to 2.48), emotionality ( rs52.25 to 2.50), depression ( rs52.26 to2.56), state anxiety ( rs52.31 to2.53), and neuroticism ( rs52.26 to2.63) (Schweizer & Koch, 2000). Divergent/Discriminant None of the POSO-E optimism subscales correlate with aggressiveness ( rs52.05 to2.16), health concerns (rs52.02 to2.09), or frankness ( rs52.07 to2.11) (Schweizer & Koch, 2000).

Reproduced with permission Positive and Negative Expectancy Questionnaire (PANEQ) (Oalson & Roger, 2001). Variable As with other conceptualizations of optimism, Oalson and Roger (2001) defined optimism as general positive expectancies. However, they noted the importance of distinguishing optimism and pessimism as more thanopposite constructs but as separate but related constructs. Description The PANEQ consists of 76 statements to which respondents indicate their degree of agreement. These state- ments reflect negative affect/pessimism, fighting spirit, and positive affect/optimism. Item response format is ona five point scale from 0 strongly disagree to 4 strongly agree. One score is obtained for each of these domainsseparately (Oalson & Roger, 2001). Sample The PANEQ was validated with a university sample ( N5216). No significant differences in optimism emerged between males ( M528.47, SD54.08) and females ( M529.21, SD54.27) (overall M528.92, SD54.20) (Oalson & Roger, 2001). Reliability Internal Consistency The Cronbach alpha coefficient reported for the PANEQ optimism subscale was .75 (Oalson & Roger, 2001). Test/C0Retest Test/C0retest reliability for the PANEQ optimism subscale was reported after an interval of six weeks ( r5.82) (Oalson & Roger, 2001). Validity Convergent/Concurrent PANEQ optimism scores correlate positively with other measures of optimism (LOT-R r5.33; GESS-R r5.27), and positive affect ( r5.11) (Oalson & Roger, 2001). Divergent/Discriminant PANEQ optimism scores do not correlate with negative affect ( r52.04) or coping ( r#2 .08) (Oalson & Roger, 2001).67 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
Construct/Factor Analytic A principal components analysis with varimax rotation as well as a separate confirmatory factor analysis supported three dimensions labeled: negative affect/pessimism, fighting spirit, and positive affect/optimism (Olason & Roger, 2001 ).

Results and Comments The PANEQ is unique in that it conceptualizes optimism and pessimism not as two sides of the same con- struct, but rather as two separate, albeit negatively related, constructs. Taking this into consideration, the PANEQ is useful for assessing both optimism and pessimism as well as ‘fighting spirit’ self-confidence. This seems to be its primary advantage above other measures which may not adequately assess these related but distinct constructs.

Cancer Patient Optimism Scale (CPOS) (Radwin et al., 2005). Variable Radwin and colleagues (2005) defined optimism as the ‘patient’s belief that he or she had made appropriate choices regarding treatment and the patient’s hopefulness about treatment outcomes’ (p. 93). Although they used hope in their definition, Radwin et al. (2005) acknowledged the limitations of measures of hope used in medical settings (e.g., Herth Hope Scale) to measure optimism (Radwin et al., 2005). Description The CPOS is part of a measure that assesses patient fortitude, trust in nurses, and authentic self- representation. Although the scale consists of 16 items, only four are devoted to assessing patient optimism. Participants are asked to answer each question using a six-point scale ranging from 1 ‘never’ to 6 ‘always.’ Scores are then transformed into a 0 /C0100 range, with higher numbers reflecting higher levels of optimism (Radwin et al., 2005).68 3. MEASURES OF HOPE AND OPTIMISM II. EMOTIONAL DISPOSITIONS
Sample The CPOS was validated with a sample of cancer patients ( N566). Optimism scores ranged from 35 to 100 (M572.62, SD513.01) (Radwin et al., 2005). Reliability Internal Consistency The Cronbach alpha coefficient for the CPOS was reported (.75) and item-scale correlations ranged from .44 to .65 (Radwin et al., 2005). Test/C0Retest No test /C0retest reliability evidence is currently available for the CPOS. Validity Convergent/Concurrent CPOS scores correlate positively with a measure of trust in nurses ( r5.33), and with a measure of authentic self-representation ( r5.20) (Radwin et al., 2005). Divergent/Discriminant No discriminant validity evidence is currently available for the CPOS. Construct/Factor Analytic No factor analytic information is currently available for the CPOS. Criterion/Predictive CPOS scores are predictive of scores on a measure of fortitude ( r5.43) (Radwin et al., 2005). Location Radwin, L.E., Washko, M., Suchy, K.A., & Tyman, K. (2005).

Results and Comments The CPOS is unique in that is applies principles of optimism to a very specific (cancer patient) population. Although the authors acknowledge that other scales have been developed to assess hope among cancer patients (i.e., Nowotny, 1989 ), they also acknowledge the dearth of scales for assessing cancer patients.

Variable Van de Ven and colleagues (2008) developed a domain-specific scale to measure optimism regarding HIV treatment programs among gay men. Description The HIV-TOS consists of 12 statements to which respondents indicate their degree of skepticism or optimism. These statements concern (1) the effectiveness of HIV treatments and (2) the hope of change in the virus. Itemresponse-format is on a four-point scale ranging from 1 strongly disagree (highly skeptical) to 4 strongly agree(highly optimistic). One score is obtained for each of these three factors separately and total scores can rangefrom 12 (highly skeptical) to 48 (highly optimistic) (Van de Ven et al., 2000). Sample The HIV-TOS was validated with a sample of men ( N5532), most of whom were HIV positive and self-identified as gay. The sample indicated a slightly skeptical orientation (overall M519.8, SD54.7) (Van de Ven et al., 2000). Reliability Internal Consistency A Cronbach alpha coefficient reported for the HIV-TOS was .79. Item total correlations ranged from .28 to .57 (Van de Ven et al., 2000). Test/C0Retest No test /C0retest reliability evidence is currently available for the HIV-TOS. Validity Convergent/Concurrent No convergent/concurrent validity evidence is currently available for the HIV-TOS. Divergent/Discriminant No discriminant validity evidence is currently available for the HIV-TOS. Construct/Factor Analytic Factor analysis yielded a three-factor solution (labeled: optimism, effectiveness of HIV treatments, and hope of change in the virus) (Van de Ven et al., 2010). Criterion/Predictive No criterion/predictive evidence are currently available for the HIV-TOS. Location Van de Ven, P., Crawford, J., Kippax, S., Knox, S., & Prestage, G. (2010).

FUTURE RESEARCH DIRECTIONS As part of the conceptual bedrock of positive psychology, hope and optimism are integral to understanding individuals’ perceptions and expectations for the future. Not surprisingly, many measures have been developed to assess the positivity or negativity of these expectations. Although space permits only a limited discussion of some of the more widely-used of these measures, it is clear that measures of hope generally reflect some level of individual responsibility in bringing about a desired state. As such, measures of hope often assess feelings of self-efficacy or motivational states that one can and will achieve a desired end goal. Conversely, measures of opti- mism reflect an individual’s general belief that good things will happen. As such, measures of optimism tend to assess a generalized expectancy of a desired end goal without self-efficacy or motivation that one can bring about that state themselves. Of course, measures of hope and optimism do overlap in that both assess some positive attitude, perception, or expectation for the future. Although the measures discussed in this chapter purport to measure similar constructs, there is variability in the nature of the items and response formats /C0even within the domains of hope and optimism themselves. To date, there is little data demonstrating the inter-relations among these measures and no data demonstrating the superiority of one measure over another. Nor is there data supporting the use of one measure among particu- lar populations relative to others. Future research should attempt to address these limitations by explicitly exam- ining response patterns and data patterns for the different measures together. Doing so could provide some evidence of the preferability of one instrument over another in a given population. Future research on hope and optimism should not only continue to develop explicit, questionnaire-based mea- sures, but also consider developing implicit or unobtrusive measures of hope and optimism. As hope and opti- mism seem to be desirable traits and/or states, it is possible that responses to self-report items may be subject to evaluation apprehension. Indeed, the average hope and optimism scores in validation studies, discussed above, seem to yield relatively high levels of these constructs. As the scales reviewed in this chapter wholly rely on explicit self-report, participants may alter their responses consciously or unconsciously. Thus, measures using implicit associations may provide useful in accessing both conscious and unconscious expectations relating to the future. Similarly, unobtrusive observations or informant reports may provide an additional glimpse into indivi- duals’ perceptions and expectations above and beyond what these individuals are willing to self-report. In line with the current trend toward development of neurological profiles of positive psychological constructs like savoring (e.g., Bryant, Chadwick, & Kluwe 2011 ), future research should consider the neurological basis of hope and optimism. Theoretically, hope relies more on self-awareness, suggesting the importance of higher order thought processes located in the prefrontal cortex, for example. Conversely, optimism might be more primal, sug- gesting a deeper, more mammalian component to its neural profile. Future research should determine the regions of interest in hope and optimism to further clarify and conceptually distinguish these distinct but related percep- tions of the future. Considerable thought and effort has gone into developing the diverse measures of hope and71 FUTURE RESEARCH DIRECTIONS II. EMOTIONAL DISPOSITIONS
optimism discussed above. Although there is still much to learn about these distinct but related constructs, the breadth (and depth) of measures purporting to assess hope and optimism highlight the wealth of knowledge accumulated by research over the last several decades. Now that this information has been accumulated, it is up to positive psychologists to continue to refine and test these measures to ensure their optimal use.

CHAPTER 4 Measures of Anger and Hostility in Adults Ephrem Fernandez1, Andrew Day2and Gregory J. Boyle3 1University of Texas, San Antonio, TX, USA;2Deakin University, Geelong, Victoria, Australia;3University of Melbourne, Parkville, Victoria, Australia Anger lags behind anxiety and depression in terms of volume of published research. Yet, anger is widely observed to be a problem in everyday life, its manifestation extending from the family to the workplace, and clin- ical settings. This has spurred many scholars to develop tools for the assessment of anger. By far, most of these tools take the form of self-report questionnaires. Some of these have been in use for more than half a century while there are also signs of a proliferation of new instruments that coincide with the increased interest in anger as a feature of everyday life and a target of self-regulation and intervention. Before delving into the individual measures, a phenomenological sketch of anger and related phenomena would be appropriate. First of all, anger has been defined in many ways with different aspects being emphasized. However, there is general consensus that it is a feeling tied to appraised wrongdoing and coupled with action tendencies to counter or redress the wrongdoing ( Smedslund, 1993; Wranik & Scherer, 2010 ). More broadly, anger has been characterized in terms of patterns of psycho-physiological and facial activation. Although anger may be deemed to have some beneficial effects, as in its role of mobilizing psychological resources, energizing behavior, and protecting self-esteem ( Taylor & Novaco, 2005 ), it is typically regarded as a negatively valenced emotion with potentially harmful consequences ( Fernandez, 2013 ). As Howells (2004) has suggested, ‘the argu- ment that angry emotions, when poorly regulated, understood and expressed, make a major contribution to human distress is a compelling one’ (p. 195). Though sometimes used interchangeably with anger, the term hostility is more specifically reserved for fre- quently recurring anger or anger proneness (Ramirez & Andreu, 2006); hostility is quite likely rooted in an attitu- dinal bias or a cognitive schema of strong disapproval toward others ( Brodsky, 2011 ). By virtue of this dispositional quality, it is akin to trait anger ( Smith, 1994 ). Aggression, which is outside the scope of this review is defined in social psychology as behavior that is intended to harm, hurt, or damage /C0physically or psychologi- cally (for a review of measures of aggression, please refer to Suris et al., 2004 ). Finally, violence is a subtype of physical aggression in which the intended harm/hurt/damage actually materializes. MEASURES REVIEWED HERE All of the scales/measures presented in this chapter have anger as at least one of the focal constructs being measured. In order to provide up-to-date psychometric reviews, the emphasis in this chapter is on research pub- lished subsequent to the appearance of the first edition of this book (Robinson, Shaver, & Wrightsman, 1991). Attention is also given to some recently constructed measures that, notwithstanding a smaller literature base, rep- resent points of innovation in this evolving field of anger assessment (cf. Biaggio & Maiuro, 1985 ). These mea- sures are presented in a more abbreviated format because of limited information concerning certain psychometric criteria. 74Measures of Personality and Social Psychological Constructs.

Basically, sub- sets of the 550 items of the MMPI were brought togeth er to form supplementary scales. The three anger assessment tools originating from the MMPI were the Cook-Medley Hostility Scale (Ho Scale; Cook & Medley, 1954 ), the Overcontrolled Hostility Scale (O-H Scale; Megargee, Cook, & M endelsohn, 1967 ), and the Hostility & Direction of Hostility Questionnaire (HDHQ; Caine, Foulds, & Hope, 1967 ). The following psycho- metric reviews do not elaborate on these MMPI-derived measures of anger because they are really supple- mentary scales of a much broader instrument for assessi ng psychopathology. Second, these first generation anger measures seem to have receded into relative obscurity. Third, these measures were generally used to obtain overall scores of hostility ra ther than different dimensions of ange r. Nevertheless, from a historical point of view, it is helpful to point out that this was the starting point in the psychometric assessment of anger/hostility. In the next section, we dedicate our efforts to reviewi ng seven self-report measures of anger or hostility for which there is relatively abundant psychometric d ata. Generally, these have a longer history than other instruments currently in use. We begin with the Buss /C0Durkee Hostility Inventory (BDHI; Buss & Durkee, 1957 ) and its successor, the Buss /C0Perry Aggression Questionnaire (BPAQ; Buss & Perry, 1992 ). This is followed by the Anger Self-Report Questionnaire (ASR; Reynolds et al., 1994 ), the Reaction Inventory (RI; Evans & Stangeland, 1971 ) including a Korean version ( Cho et al., 2009 ), the Novaco Anger Scale and Provocation Inventory (NAS-PI; Novaco, 1994, 2003 ), the Multidimensional Anger Inventory (MAI; Siegel, 1986 ), and finally, the State /C0trait Anger Expression Invent ory-2nd Edition (STAXI-2; Spielberger, 1988, 1999 ). In the subsequent section we provide brief summarie s of nine measures, most of them newer and with less psychometric data. These include the Anger Disorders Scale (ADS; DiGiuseppe & Tafrate, 2004 ), the Anger Parameters Scale (APS; Fernandez et al., 2010, 2014 ), the Awareness and Expression of Anger Indicator (AEAI; Catchlove & Braha, 1985 ), the Standardized Experience of Anger Measure (SEAM; Linden et al., 1997 ), the Anger Control Inventory (ACI; Hoshmand & Austin, 1987 ), the Anger Discomfort Scale (ADS; Sharkin & Gelso, 1991 ), the Anger Related Reactions and Goals Inventory (ARGI; Kubiak et al., 2011 ), the Anger Readiness to Change Questionnaire (AECQ; Williamson et al., 2003 ), and finally, the Short Anger Measure (SAM; Gerace & Day, 2014).75 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
MEASURES REVIEWED IN DETAIL Buss/C0Durkee Hostility Inventory (BDHI) (Buss & Durkee, 1957 ). Variable Historically, anger/hostility has been viewed as a multidimensional construct as reflected, for example, in the eight dimensional BDHI measure. Description The BDHI is a 75-item self-report inventory (60 direct items; 15 reverse worded items) intended to measure aspects of anger/hostility and aggression. The BDHI comprises ‘subscales labeled Assault (10 items), Indirect [hostility] (9 items), Irritability (11 items), Negativism (5 items), Resentment (8 items), Suspicion (10 items), Guilt (9 items), and Verbal [hostility] (13 items). So many factor-analyses of the inventory have been published that a meta-analysis of the factor-analyses has appeared ( Bushman, Cooper, & Lemke, 1991 ), (Leenaars & Lester, 2011 , p. 66). Buss and Durkee (1992) reported that, ‘The correlation between social desirability and probability of endorsing the items was .87’ (p. 345). Even after curtailment of the range of social desirability responding, the correlation was still .74, suggesting that the early BDHI items were unduly influenced by social desirability responding. However, after rewriting several of the items the correlation with social desirability decreased to .27 (males) and .30 (females), respectively. Responses are on a 6-point rating scale. The BDHI has now been translated into several different languages. Sample The initial factor analytic sample comprised 173 undergraduates (85 males; 88 females), item analyses were based on 159 (85 male; 74 female) and 120 (62 male; 58 female) undergraduates, and social desirability responding was investigated using 120 undergraduate ‘judges’ (85 male; 35 female) and 120 undergraduate respondents (62 male; 58 female), respectively. Buss and Durkee (1957) provided norms for 173 undergraduates (85 males; 88 females). More recently, a Dutch adaptation of the BDHI was based on a sample of 463 undergradu- ates ( Lange et al., 1995 ), and a Spanish adaptation of the BDHI has also been constructed ( Oquendo et al., 2001 ). Reliability Internal Consistency Items selected for inclusion in the 75-item BDHI satisfied ‘internal consistency criteria’. KR-20 coefficients were reported for the two higher-order factors as follows: Covert anger/hostility (.76) and Overt aggression (.72) (see Pittsburgh Mind Body Center (PMBC) website /C0Retrieved January 16, 2014). http://pmbcii.psy.cmu.edu/core_c/ Buss-Durkee_Hostility_Inventory.html . Similarly, a Dutch adaptation (BDHI-D) exhibited Cronbach alpha coefficients for the two components they had extracted of 0.77 (Overt Aggression) and 0.79 (Covert Aggression) /C0(Lange et al., 1995 ). Test/C0Retest Stability coefficients over a two-week test /C0retest interval were reported by Biaggio, Supplee, and Curtis (1981) based on a sample of 60 undergraduate students as follows: Assault (.78), Indirect Hostility (.68), Irritability (.64), Negativism (.64), Resentment (.66), Suspicion (.68), Verbal Hostility (.77), Guilt (.72), and BDHI Total (.82). Validity Convergent/Concurrent As evidence of convergent/concurrent validity, in a Dutch validation study ( Lange et al.,1995 ) positive correla- tions ( N538) were found between the BDHI-D Covert Aggression component and the SCL-90 psychopathology subscales ( Derogatis, 1977 ) as follows: Anxiety (.58), Agoraphobia (.45), Depression (.52), Somatization (.38), Insufficiency (.56), Sensitivity (.55), Hostility (.47), Sleeplessness (.34) and Psychoneuroticism (.64), with the VIR (Interpersonal Relations Questionnaire; Vertommen & Rochette, 1979 ) subscales Hostility (.24), and Bitterness (.54), and with the MMPI subscale Negativism (.29). In addition, the Overt Aggression component correlated76 4. ANGER/HOSTILITY MEASURES II. EMOTIONAL DISPOSITIONS
positively with VIR Hostility (.64), VIR Bitterness (.24), and MMPI Negativism (.54). As well, the total BDHI-D scores correlated positively with all nine of the SCL-90 psychopathology subscales ranging from .13 to .43 (for Depression), and with VIR Hostility (.60), VIR Bitterness (.51), and MMPI Negativism (.57) (see Lange et al., 1995). Also, the BDHI has been found to correlate positively with measures of trait anxiety ( Matthews & Saal, 1978) and with other self-report measures of anger/hostility/aggression (ranging from .40 to .70) ( Matthews, Jamison, & Cottington,1985 ). Divergent/Discriminant As evidence of divergent/discriminant validity, in the Dutch validation study, negative correlations ( N538) were found between the BDHI-D Covert Aggression component and MMPI Extraversion ( /C0.12), the NPV (Luteijn, Starren, & Van Dijk, 1975 ) Dominance ( /C0.21), and Crowne and Marlowe’s (1960) Social Desirability Scale (/C0.37). In addition, the BDHI-D Overt Aggression component exhibited negligible correlations with each of the nine SCL-90 psychopathology subscales (ranging from /C0.30 to .15), and also correlated negatively with Social Desirability ( /C0.44). As well, negative correlations were found between BHDI-D total scores and MMPI Extraversion ( /C0.07), NPV Dominance ( /C0.19), and Social Desirability ( /C0.55) (see Lange et al., 1995 ). Also, Biaggio (1980) reported that the BDHI Total score correlated negatively ( /C0.56) with the Marlowe /C0Crowne Social Desirability Scale. Biaggio et al. (1981) further reported mostly negative correlations (ranging from .09 to /C0.38) between the BDHI Total and the Personal Incidents Record (a record of all incidents which provoked anger). Construct/Factor Analytic As evidence of construct/factor analytic validity, Buss and Durkee (1957) reported the results of an explor- atory factor analysis using Thurstone’s (1947) centroid method on separate relatively small samples of male (N585) and female ( N588) undergraduates, respectively. Two factors were extracted. For both the men and women, the first factor loaded significantly on BDHI subscales: Resentment (.59 and .57) and Suspicion (.66 and .54), respectively. Likewise, for both men and women, the second factor loaded significantly on BDHI subscales: Assault (.54 and .61), Indirect Hostility (.40 and .48), Irritability (.57 and .47), and Verbal Hostility (.63 and .49), respectively. For women, there was also a significant factor loading on the BDHI Negativism subscale. The two factors represented emotional anger/hostility, and aggressive behavior, also described as Neurotic hostility and Expressive hostility ( Bushman et al., 1991; Felsten & Leitten, 1993; Siegman, Dembroski, & Ringel, 1987 ) (see PMBC website). As Biaggio (1980) had previously indicated, ‘Factor analysis produced two factors: an attitudinal component of hostility (Resentment and Suspicion subscales) and a ‘motor’ (Expressive) component (Assault, Indirect Hostility, Irritability, and Verbal Hostility subscales)’ (pp. 289 /C0290). A meta-analysis of the many BDHI factor-analytic studies has been carried out and it is evident that the BDHI measures both affective and behav- ioral components of anger/hostility and aggression, respectively ( Bushman et al., 1991 ). Criterion/Predictive As evidence of criterion/predictive validity, Lange, Dehghoni, and De Beurs (1995) reported that BDHI scores are predictive of aggressive behavior. Also, according to the PMBC website (see link above): (1) BDHI Expressive hostility scores appear to relate to central serotonergic depletion ( Cleare & Bond, 1997; Coccaro et al., 1989 ); (2) During interpersonal stress, Expressive hostility scores are predictive of cardiovascular reactivity ( Felsten & Leitten, 1993; Siegman, Anderson, Herbst, Boyle, & Wilkinson, 1992; Suarez & Williams, 1990 ); (3) Expressive hostility scores are predictive of coronary disease among patients younger than 60 years ( Siegman, 1994; Siegman et al., 1987 ); and (4) Both BDHI Assault and Irritability scores are reduced in individuals following SSRI ingestion (Knuston et al., 1998). In addition, Musante, MacDougall, Dembroski, and Costa (1989) reported that, ‘The BDHI has been related (a) to behavioral measures, including shock administration and role-playing responses to anger-provoking circumstances; (b) to greater perception of violence in binocular rivalry technique; and (c) to expert ratings of aggressiveness’ (p. 346).

Results and Comments The BDHI was the first major multidimensional measure of anger/hostility/aggression. It has been in use for over five decades, and has been used in thousands of research studies. The stability of the BDH over varying77 MEASURES REVIEWED IN DETAIL II. EMOTIONAL DISPOSITIONS
time intervals might be subjected to further investigation. Also, the BDHI subscale structure has not been fully supported in factor analytic studies that have been based on more up-to-date factor analytic methodology (cf.Bushman et al., 1991 ;Buss & Perry, 1992 ). This deficiency motivated construction of the BPAQ which was based on more recently devised factor analytic methods, and is reviewed next. BDHI SAMPLE ITEMS Scale Sample item statement ASSAULT I have known people who pushed me so far that we came to blows. INDIRECT I sometimes spread gossip about people I don’t like. IRRITABILITY I can’t help being a little rude to people I don’t like. NEGATIVISM When someone is bossy, I do the opposite of what he asks. RESENTMENT Other people always seem to get the breaks. SUSPICION I tend to be on my guard with people who are somewhat more friendly than I expected. VERBAL Even when anger is aroused, I don’t use ‘strong language.’* GUILT The few times I have cheated, I have suffered unbearable feelings of remorse. Notes : Items currently rated on a 6-point scale: *Reverse worded item. The BDHI can be administered using a two-choice (agree or disagree) and six-choice response format version (15Strongly disagree to 6 Strongly agree ). A study by Velicer, Govia, Cherico, and Corriveau (1985) concluded that the two-choice version provided some support for the present theoretical structure, but was not stable across administrations, whereas the six-choice version resulted in a structure that was different, but more stable across repeated administrations. Buss/C0Perry Aggression Questionnaire (BPAQ) (Buss & Perry, 1992 ). Variable Revision of the BDHI item pool has resulted in the emergence of a new measure ( Buss & Perry, 1992 ). The BPAQ includes four components of Physical aggression, Verbal aggression, Anger, and Hostility (cf. Lange et al., 1995 ). Description Buss and Perry (1992) added additional items to the BDHI item pool and following a factor analysis of the item inter-correlations, the resultant BPAQ consisted of 29 items structured into four subscales as follows: Physical Aggression (9 items), Verbal Aggression (5 items), Anger (7 items), and Hostility (8 items) (see Lange et al., 1995 ). The BPAQ utilizes a 5-point Likert-type response format. As compared with the BDHI, the BPAQ has improved structural properties as well as capturing all three cognitive, affective, and behavioral dimensions of the hostility construct. The BPAQ has been used in studies conducted in several different countries including the USA, Canada, Italy, the Netherlands, Germany, Japan, Greece, and Egypt (see Abd-El-Fattah, 2007). Sample The BPAQ was based on an initial sample of 1253 university students (612 males; 641 females) aged from 18/C020 years ( Buss & Perry, 1992 ). The total sample consisted of three separate subsamples of undergraduates (Ns5406, 448, and 399, respectively). Bernstein and Gesn (1997) based their analyses of the BPAQ structure on a sample of 321 undergraduates (113 males; 208 females). In an Italian version of the BPAQ, Fossati et al. (2003) uti- lized samples of 563 high school students, and 392 university students. Diamond, Wang, and Buffington-Vollum (2005) utilized a sample of 383 male prisoners in testing a variety of factor models for the BPAQ, in addition to a cross-validation sample of 403 male prisoners ( Total N 5786; M534 years, range 19 /C068 years). Abd-El-Fattah78 4. ANGER/HOSTILITY MEASURES II. EMOTIONAL DISPOSITIONS
(2007) utilized a sample of 510 (265 males; 245 females) secondary school students ( M516.3 years, range 16 /C028 years). Reliability Internal Consistency Buss and Perry (1992) reported Cronbach alpha coefficients for the BPAQ subscales ( N51253) as follows: Physical Aggression (.85), Verbal Aggression (.72), Anger (.83), Hostility (.77), and BPAQ Total (.89). Fossati et al. (2003, p. 62) reported alpha coefficients ( N5563) as follows: Physical Aggression (.81), Verbal Aggression (.53), Anger (.72), and Hostility (.68), and ( N5392) as follows: Physical Aggression (.85), Verbal Aggression (.53), Anger (.72), and Hostility (.78). Abd-El-Fattah (2007) reported alpha coefficients for the four BPAQ subscales as follows: Physical Aggression (.82), Verbal Aggression (.81), Anger (.83), and Hostility (.80). Evren, Cinar, Gulec, Celik, and Evren (2011) reported alpha coefficients ( N5166) ranging from .59 to .93 for the Turkish version of the BPAQ. Subsequently, Demirtas-Madran (2013) reported alpha coefficients for the Turkish version ( N5220) as follows: Physical Aggression (.78), Verbal Aggression (.48), Anger (.76), Hostility (.71), and BPAQ Total (.85). Test/C0Retest Buss and Perry (1992) reported stability coefficients for the BPAQ subscales ( N51253) across a nine-week test/C0retest interval as follows: Physical Aggression (.80), Verbal Aggression (.76), Anger (.72), Hostility (.72), and BPAQ Total (.80). Diamond et al. (2005) reported alpha coefficients for the four subscales in the Bryant and Smith (2001) short form that ranged from .63 to .73. Likewise, Evren et al. (2011) reported two-week test /C0retest reliabil- ity coefficients ( N5166) ranging from .54 to .84 for the Turkish version of the BPAQ. Subsequently, Demirtas- Madran (2013) reported stability coefficients over a four-week interval as follows: Physical Aggression (.98), Verbal Aggression (.82), Anger (.85), Hostility (.85), and BPAQ Total (.97). Validity Convergent/Concurrent As evidence of convergent/concurrent validity, Buss and Perry (1992) reported positive correlations between the BPAQ subscales and various trait measures as follows: BPAQ Physical Aggression correlated .20 (men) with Activity, .28 with Impulsiveness, .28 with Assertiveness, and .36 with Competitiveness. BPAQ Verbal Aggression correlated .31 with Impulsiveness, .49 with Assertiveness, and .39 with Competitiveness. BPAQ Anger correlated .43 with Emotionality .22 (men) with Activity, .42 with Impulsiveness, .40 with Assertiveness, .32 with Competitiveness, and .20 (women) with Private self-consciousness. BPAQ Hostility correlated .52 with Emotionality, .37 with Impulsiveness, .30 with Competitiveness, .32 (men) and .49 (women) with Public self-consciousness, and .24 with Private self-consciousness ( Buss & Perry, 1992 ). Total BPAQ scores correlated .35 with Emotionality, .25 (men) with Activity, .46 with Impulsiveness, .43 with Assertiveness, .46 with Competitiveness, .20 with Public self-consciousness, and .25 (women) with Private self-consciousness. Bernstein and Gesn (1997) reported that the BPAQ subscales exhibited positive inter-correlations (ranging from .34 to 1.00), indicative of their convergent/concurrent validity. Divergent/Discriminant As evidence of divergent/discriminative validity, Buss and Perry (1992) also reported divergent/discriminant validity evidence as follows: BPAQ Physical Aggression did not correlate significantly with Emotionality, Activity (women), Sociability, Public self-consciousness, Private self-consciousness, or Self-esteem. BPAQ Verbal Aggression did not correlate significantly with Emotionality, Sociability, Public self-consciousness, or Self-esteem. BPAQ Anger did not correlate significantly with Activity (women), Sociability, Private self-consciousness (men), and was negatively correlated with Self-esteem ( /C0.14 men; /C0.27 women). BPAQ Hostility did not correlate signif- icantly with Activity, and was negatively correlated with Sociability ( /C0.12), and Self-esteem ( /C0.49). Construct/Factor Analytic As evidence of construct/factor analytic validity, Buss and Perry (1992) performed separate exploratory principal-axis factor analyses with oblimin rotation on the BDHI item intercorrelations using samples of 406, 448, and 399 undergraduates, respectively. Four factors were extracted and labeled: Physical Aggression, Verbal Aggression, Anger, and Hostility. A confirmatory factor analysis carried out on the second subsample of univer- sity students ( N5448), provided additional support for the four-factor structure. Bernstein and Gesn (1997)79 MEASURES REVIEWED IN DETAIL II. EMOTIONAL DISPOSITIONS
found support for the four-factor BPAQ structure in a sample of undergraduates ( N5321). Bryant and Smith (2001) also found support for the four factor structure using a modified 12-item short form of the BPAQ. Fossati et al. (2003) carried out confirmatory factor analyses in Italian samples ( Ns5392 and 563), finding strong support for the four factor structure. Diamond et al. (2005) in confirmatory factor analyses ( Ns5383 and 403) found sup- port for the Bryant and Smith four factor model ( χ2 (48)5110.9, χ2/df52.3, GFI 5.96, RMSEA 5.06, CFI 5.95, NNFI5.94) Abd-El-Fattah (2007) using a sample of 510 Egyptian high school students provided support for the four factors. In a subsequent confirmatory factor analysis, Abd-El-Fattah reported that the BPAQ comprised ‘four first level factors that were linked by a higher order factor of general aggression’ (p. 237). CFA results for this four-factor best-fitting model ( N5510) were: χ2 (371)5385.6 (n.s.), RMSEA 50.01, SRMR 50.02, AGFI 50.99, PGFI50.29, TLI 50.99, PRATIO 50.85, and PNFI 50.83. The four factor structure of the BPAQ has also received support in several other factor analytic studies including: Harris (1995) ;Meesters, Muris, Bosma, Schouten, and Beuving (1996) ;Williams, Boyd, Cascardi, and Poythress (1996) ;Nakano (2001) [Japanese version]; von Collani and Werner (2005) [German version]; Diamond et al. (2005) ;Vigil-Colet, Lorenzo-Seva, Codorniu-Raga, and Morales (2005) ; and Tsorbatzoudis (2006) [Greek version]; and Demirtas-Madran (2013) [Turkish version]. Criterion/Predictive Predictive validity evidence has been summarized by the Pittsburgh Mind Body Center (PMBC): http://pmbcii. psy.cmu.edu/core_c/Buss_Perry_Aggression_Questionnaire.html (Retrieved January, 16, 2014). For example, Smith and Gallo (1999) reported that (among men), the BPAQ Hostility subscale predicted increased blood pres- sure response to interpersonal threat. PMBC also reported that, following provocation, BPAQ scores exhibit a lowered threshold for anger, and a reduced threshold for aggression (subsequent to tryptophan depletion; Dougherty, Bjork, Marsh, & Moeller, 1999 ) or alcohol consumption ( Giancola, 2002 ). BPAQ scores are predictive of inflammatory processes ( Suarez, Lewis, & Kuhn, 2002 ) and C-reactive protein ( Suarez, 2004 ). Also, BPAQ scores are predictive of the severity of coronary disease for men under 60 years ( Gidron, Davidson, & Ilia, 2001 ). Location Buss, A.H., & Perry, M. (1992). The Aggression Questionnaire. Journal of Personality and Social Psychology , 63, 452–459. Results and Comments Some 35 years after constructing the BDHI, Buss ( Buss & Perry, 1992 ) constructed a new instrument (BPAQ). Several exploratory and confirmatory factor analytic studies using large samples in a variety of different coun- tries have confirmed that a general anger/hostility/aggression factor can be broken down into four major sub- factors corresponding to the BPAQ subscales labeled: Physical aggression, Verbal aggression, Anger, and Hostility, respectively. The first two factors measure the behavioral and cognitive components while the remain- ing two factors (anger and hostility) measure the affective component. As Fossati et al. (2003) concluded, there is a ‘need to measure not only overall aggression but also its components’ (p. 64). There is considerable evidence showing that the BPAQ is predictive of real-life health outcomes. BPAQ SAMPLE ITEMS Please rate each of the following items in terms of how characteristic they are of you. Use the following scale for answering these items. 12 3 4 5 Extremely uncharacteristic of me Extremely characteristic of me Scale Sample item statement Physical aggression Given enough provocation, I may hit another person. Verbal aggression I can’t help getting into arguments when people disagree with me. Anger Sometimes I fly off the handle for no good reason. Hostility I am suspicious of overly friendly strangers.

Anger Self-Report Questionnaire (ASR) (Reynolds et al., 1994; Zelin et al., 1972 ). Variable The distinction between awareness of one’s angry/hostile feelings and the expression of aggression in one’s behavior is an important one. Accordingly, the ASR focuses on measuring anger/hostility both in terms of one’s awareness of anger and its behavioral expression ( Zelin et al., 1972 ). As Musante et al. (1989) pointed out, the ASR was ‘explicitly designed to remove the confounding that previous anger/hostility inventories have made between awareness of angry feelings and expression of hostility/anger in behavior’ (p. 346). Description In an item analysis of the original ASR ( N5138), Zelin et al. (1972) reduced the ASR item-pool from 89 items down to 64 items (with removal of 25 filler items). The resultant subscales were labeled as follows: Awareness of anger, Expression of anger (comprising General, Physical, and Verbal expression subscales), Guilt, Condemnation of Anger, and Mistrust ( Zelin et al., 1972 ; cf.Matthews et al., 1985 ;Musante et al., 1989 ;Reynolds et al., 1994 ). A 30-item short form is also available ( Reynolds et al., 1994 ). Sample The initial sample ( Zelin et al., 1972 ) comprised 138 individuals used for the item analysis of the 89-item ver- sion of the ASR, followed by samples of 82 psychiatric patients and 67 undergraduates used for validating the psychometric properties of the abbreviated 64-item version. Reynolds et al. (1994) administered both the 89-item and 64-item versions to a sample of 246 undergraduate students (127 males; 119 females) ranging in age from 16 to 47 years. Norms for 30-item short form were derived from the responses of 101 male and 100 female under- graduates (Reynolds et al., p. 64). Reliability Internal Consistency Split-half coefficients for the ASR subscales ranged from .64 to .82 ( Zelin et al., 1972 ). More recently, Reynolds et al. (1994) reported split-half coefficients for the Physical expression (.64) and General expression subscales (.66), respectively), and that 39 out of the total 89 items correlated positively with total scores, ranging from .28 to .66 (Reynolds et al., p. 66). While the KR 20coefficient was .85 for all 89 items ( N5246), those for the ASR sub- scales were somewhat lower, as follows: General expression (.48), Mistrust (.57), Verbal expression of anger (.70), and Awareness of anger (.79). Test/C0Retest Biaggio et al. (1981) reported two-week test /C0retest stability coefficients for the ASR subscales as follows: Awareness (.54), General (.45), Physical (.63), Verbal (.35), Guilt (.28), Condemnation (.76), Mistrust (.53), and ASR Total (.54). Validity Convergent/Concurrent As evidence of convergent/concurrent validity, Biaggio (1980) reported that BDHI Total Hostility and ASR Total Expression scores correlated positively (.64). Biaggio (p. 295) further pointed to the positive correlations between the BDHI and ASR subscales (ranging from .28 to .78). Subsequently, Biaggio (1981, Table 1) reported positive correlations between the ASR Total Expression scale and self-monitored incidents of Verbal expression of anger (.38), and Physical expression of anger (.31). Likewise, Schill, Ramanaiah, and Conn (1990) reported (N565) that ASR and BDHI scores correlated .60 (males) and .66 (females). Also, Reynolds et al. (1994, Table 1) reported that two-thirds of the ASR subscale inter-correlations were significant ( p,.001). Divergent/Discriminant As evidence of divergent/discriminant validity, Zelin et al. (1972) , reported that, ‘A multi-trait, multi-method analysis ...yielded substantial convergent and discriminant validities for the ASR scales ...Furthermore, aware- ness lacked significant correlations with PAS scales reflecting the expression of anger, thereby demonstrating its81 MEASURES REVIEWED IN DETAIL II. EMOTIONAL DISPOSITIONS
discriminant validity’ (p. 340). Biaggio (1980, p. 296) reported that only the ASR subscales (Awareness of anger, General Expression, Guilt, and Mistrust) correlated with BDHI Guilt and that only the BDHI subscales (Irritability, Resentment, Suspicion, and Guilt) correlated significantly with ASR Guilt, indicative of the latter’s discriminant validity. As well, Biaggio (1980) reported that the ASR Total Expression score correlated negatively (/C0.40) with the Marlowe /C0Crowne Social Desirability Scale. Also, Biaggio et al. (1981) reported negative or negli- gible correlations (ranging from .07 to /C0.31) between the ASR and three of the Personal Incidents Record (Condemnation of Anger, Guilt, Indirect Expression) measures. Construct/Factor Analytic As evidence of construct/factor analytic validity, Reynolds et al. (1994) reported that, ‘Factor analyses were conducted on the 89 item questionnaire to compare the seven factor and five factor solutions using analyses obtained from three samples of 82 subjects’ (p. 66). Neither the 5-factor nor the 7-factor structure could be repli- cated. Reynolds et al. subsequently undertook a factor analysis based on the item inter-correlations of the 64-item version (in a previous study, Biaggio, 1980 , had been unable to replicate the claimed ASR factors). Again, Reynolds et al. could not find support for the purported subscale structure, leading them to conclude that the ASR is unidimensional, comprising only a general anger factor. Criterion/Predictive As evidence of criterion/predictive validity, Zelin et al. (1972) reported that, ‘ASR scores were correlated with psychiatrists’ ratings on the 16 most relevant Problem Appraisal Scales (PAS) ...the highest correlation (.41) for the Physical expression scale is with ratings of assaultive acts on the PAS’ (p. 340). Zelin et al. also reported several additional predictive validity correlations. For example, verbal expression of anger correlated /C0.36 with a measure of dependency, .31 with real-life anger, belligerence and negativism, and .28 with antisocial attitudes and acts. Awareness of anger correlated .24 with antisocial attitudes and acts, and /C0.37 with rating of obsessive- compulsive behaviors. ASR Guilt correlated .48 with suicidal thoughts, and .33 with a measure of depression- inferiority. ASR Mistrust correlated .33 with a measure of mistrust and suspicion.

Results and Comments The ASR could benefit by further exploration of its stability over varying time intervals. Also, Reynolds et al. (1994) concluded that previous studies have provided ‘only modest evidence for discriminant, convergent and pre- dictive validity of the ASR ...[and]...Factor analyses [have] provided little support for ...construct validity’ (p. 68). In light of these inconclusive factor analytic findings, Reynolds et al. constructed a 30-item short form of the ASR as a measure of a general anger factor. This unidimensional measure of anger is a departure from the clinical quest to differentiate subtypes of anger and hostility already well recognized in phenomenological accounts. It is not surprising therefore, that the ASR and its short forms have been eclipsed by alternative measures. ASR SAMPLE ITEMS ‘I will criticize someone to their face if they deserve it.’ ‘At times, I feel like smashing things.’ ‘When I really lose my temper, I am capable of slapping someone.’ Notes : Items are rated on a 6-point scale ranging from: 1 5Strongly agree to 6 5Strongly disagree. Reaction Inventory (RI) (Cho et al., 2009; Evans & Stangeland, 1971 ).82 4. ANGER/HOSTILITY MEASURES II. EMOTIONAL DISPOSITIONS
Variable Anger may arise in response to a variety of everyday stimulus situations often involving frustration of one’s efforts. It is possible to vicariously arouse anger through invoking hypothetical imaginary scenarios. Imagining such scenarios may ‘evoke anger, and thereby offer clues about an individual’s propensity for anger arousal. However, hypothetical scenarios of the kind featured in the RI often run the risk of being over-specific and thus of limited generalizability across test-takers ( Fernandez, 2008 , p. 406). Description The original RI was devised by Evans and Stangeland (1971) . The RI presents 76 intuitively selected items that may incite anger, tapping into 10 hypothetical scenarios derived factor analytically (see below) including: Minor chance annoyances, Destructive people, Unnecessary delays, Inconsiderate people, Self-opinionated people, Frustration in business, Criticism, Major chance annoyances, People being personal, and Authority. Individuals respond on a 5-point Likert-type rating scale indicating the degree to which they would be angered by each scenario. In addition, a Korean adaptation of the RI has been produced ( Cho et al., 2009 ). Although the RI was con- structed to measure ‘the number and type of incidents that arouse anger’ ( Leenaars & Lester, 2011 , p. 65), it remains ‘an instrument that has been on the periphery of anger assessment methodology’ ( Fernandez, 2008 , p. 406). Sample Evans and Stangeland (1971) utilized a heterogeneous sample of 275 university and non-university students (84 males; 191 females) ranging in age from 16 to 75 years (Mdn 521 years). The total sample consisted of four separate subsamples: Sample 1 (16 males; 29 females; Mdn 525 years), Sample 2 (10 males; 21 females; Mdn 522 years), Sample 3 (30 males; 108 females; Mdn 518 years), and Sample 4 (friends and family members who had not attended university: 28 males; 33 females; Mdn 526 years). Subsequently, a Korean adaptation of the RI (Cho et al., 2009 ) utilized a sample of 216 elderly depressed patients (170 women, 46 men; M571.6 years, SD56.3) and a separate sample of 198 normal elderly individuals (128 women, 70 men; M572.6 years, SD55.9) (Baeg, Wang, Chee, Kim, & Kim, 2011 ). Reliability Internal Consistency Taking the mean item-test correlation (.46) as the starting point, and using Gaylord’s formula, the estimated internal consistency coefficient was found to be .95 ( Evans & Stangeland, 1971 ). However, such a high level of ‘internal consistency’ may be problematic in terms of possible item redundancy and inadequate breadth of measurement of a scale (cf. Boyle, 1991 ). Test/C0Retest Biaggio et al. (1981, Table 1) using a sample of 60 undergraduate students reported a two-week test /C0retest reliability coefficient of .70. Validity Convergent/Concurrent As evidence of convergent/concurrent validity, the RI total score was found to correlate positively (.52) with the BDHI in a subsample of 45 undergraduates (16 males; 29 females), and .57 in a separate sample of 138 under- graduates (30 males; 108 females; Mdn 518 years ( Evans & Stangeland, 1971 ). Also, Biaggio (1980) reported that in a sample of undergraduates ( N5150), the RI correlated positively and highly (.82) with the conceptually simi- lar NAS, showing substantial overlap in measurement variance and evidence of convergent/concurrent validity. Divergent/Discriminant As evidence of divergent/discriminant validity, Biaggio (1980, p.296) reported that the RI correlated negatively (/C0.29) with the Marlowe /C0Crowne Social Desirability Scale. As further evidence of discriminative validity, Biaggio also reported the results of a factor analysis based on the subscale inter-correlations for the BDHI, ASR, RI, and AI measures combined ( N5150) wherein she obtained four factors. Indicative of discriminative validity, the NAS was loaded by a separate factor (together with the RI), and did not overlap with the BDHI and ASR measures which were loaded by other factors. Subsequently, Biaggio et al. (1981) reported negligible correlations (ranging from .05 to /C0.22) between the RI and the Personal Incidents Record .83 MEASURES REVIEWED IN DETAIL II. EMOTIONAL DISPOSITIONS
Construct/Factor Analytic As evidence of construct/factor analytic validity, a principal axis factor analysis ( N5275) with varimax rota- tion of the inter-correlations of the 76 items with factor extraction number based on the eigenvalues greater than 1.0 criterion produced 10 factors, as listed above ( Evans & Stangeland, 1971 ). In the subsequent development of a Korean version of the RI ( Cho et al., 2009 ), four higher-order factors were extracted and labeled: Unpredictable disruptions and Disturbances, Embarrassing circumstances, Personal disrespect, and Unpleasant encounters, respectively. Clearly, there is a multitude of situations that have the potential to provoke anger, as recognized in the multidimensional structuring of the RI. Criterion/Predictive In a Korean study ( Baeg et al., 2011 ), depressive symptomatology among the elderly was positively predicted by the RI anger factors with the sole exception of the factor labeled Unpleasant Encounters. Thus, ‘the more severe the depressive symptoms ...the more severe the anger reaction to unpredictable disruption and disturbances, embarrassing situations, and personal disrespected factor scores on the RI were ( p,.05)’ (Baeg et al., p. 189).

Results and Comments The stability of the RI over various periods of time needs to be investigated further. Also, although mere imagina- tion of the provocative scenarios included in the RI has the potential to evoke anger, that would depend on the degree of absorption into the imagined situations. Moreover, hypothetical provocation scenarios of the kind included in measures such as the RI or NAS-PI, run the risk of being over-specific and may provide an anger trigger for only a small fraction of the population. If so, this would limit the relevance of the items across respondents.

Variable Anger disposition has been conceptualized as consisting of distinct cognitive, arousal, and behavioral compo- nents ( Novaco, 1975 ). On the other hand, certain anger-eliciting situations can lead to the arousal of anger in response to such provocation ( Novaco, 1994 ). Description The Novaco Anger Scale (NAS) was constructed by Novaco (1975) as a measure of anger reactions to various provocations. It was revised by Novaco (1994) having 48 items relating to cognitive, behavioral, and arousal com- ponents of anger (with the cognitive component comprising subscales of attentional focus, rumination, hostile attitude, and suspicion). The PI comprises 25 hypothetical situations that are likely to provoke anger, distributed across five subscales labeled: Disrespectful treatment, Unfairness/injustice, Frustration/interruptions, Annoying traits, and Irritations. Further revisions of the NAS-PI have appeared, the most recent being the commercially produced version ( Novaco, 2003 ).84 4. ANGER/HOSTILITY MEASURES II. EMOTIONAL DISPOSITIONS
Sample An early sample comprised 353 undergraduate students ( Novaco, 1977 ). Subsequently, Novaco (1994) uti- lized 142 hospital inpatients and another sample of 158 pat ients in undertaking initial validational studies. Biaggio (1980) utilized a sample of 150 undergraduate students ( 72 male; 78 female) in her validation study of the original NAS. Mills, Kroner, and Forth (1998) compared samples of 102 non-violent offenders ( M533 years, range 19 /C069 years) with 102 violent offenders ( M528 years, range 18-55). Jones, Thomas-Peter, and Trout (1999) investigated the NAS-PI in a sample of 58 men ( M532.47 years, SD 58.32), Monahan et al. (2001) uti- lized a sample of 1102 mentally disturbed inpatients. Jones, Thomas-Peter, and Gangstad (2003) used a sample of 354 anger management outpatients, Lindqvist, Waterman, and Hellstro ¨m (2003) employed a sample of 100 male undergraduates ( M533.2 years, SD512.5), Lindqvist, Waterman, and Hellstro ¨m (2005) utilized a sample of 95 violent prisoners (ranging from 18 /C067 years), Baker, Van Hasselt, and Sellars (2008) utilized samples of prisoners (638 males; 349 females). Hornsveld, Muris, and Kraaimaat (2011) utilized samples of 142 male foren- sic psychiatric inpatients ( M533.16 years, range 21 /C056 years), 194 male outpatients ( M522.79 years, range 16/C056 years), and 320 secondary vocational students (160 males; M517.35 years, range 16 /C021; 160 females; M518.36 years, range 16 /C027 years). Finally, the commercially prod uced version of the NAS-PI was validated on an age-stratified national standardization s ample of 1546 non-clinical individuals aged from 9 /C084 years (Novaco, 2003 ). Reliability Internal Consistency Novaco (1977) reported an alpha coefficient ( N5353) for the original NAS of .96 (cf. Biaggio, 1980 ;Boyle, 1991).Novaco (1994) reported alpha coefficients ( N5126) for the NAS (.95), and PI (.95). Mills et al. (1998) reported alpha coefficients NAS (.95) and PI (.96) in non-violent sample (N 5102), and NAS (.94) and PI (.95) in violent sample ( N5102). Jones et al., (1999) reported alpha coefficients for NAS (.92) and PI (.92). Novaco and Taylor (2004) reported an alpha coefficient of 0.92 for both the NAS and PI modified versions. Lindqvist et al. (2005) reported alpha coefficients ranging from .78 to .91. Baker et al. (2008) reported alpha coefficients for men on the NAS (.93) and PI (.92), and women on the NAS (.89) and PI (.87), respectively. Hornsveld et al. (2011) reported alpha coefficients for the NAS subscales ranging from .77 to .95, and the PI for inpatients (.90) and out- patients (.94), respectively. Test/C0Retest Novaco (1994) reported stability coefficients over an interval of two weeks for the NAS (.84) and PI (.86). Mills et al. (1998) reported stability coefficients over a four-week interval for NAS (.89) and PI (.85). Cornell, Peterson, and Richards (1999) reported alpha coefficients for the NAS (.94) and PI (.91). Subsequently, Hornsveld et al. (2011) using a group of 90 forensic psychiatric outpatients, reported stability coefficients for the NAS over a four- week interval as follows: NAS Anger (.80), NAS Cognitive (.71), NAS Arousal (.78), and NAS Behavior (.79), respectively. They also reported a high alpha coefficient (.90) for the PI (cf. Boyle, 1991 ). Validity Convergent/Concurrent As evidence of convergent/concurrent validity, Biaggio (1980) had reported positive correlations ( N5150) between the NAS and all eight BDHI subscales plus BDHI Total score (ranging from .05 to .45), with all seven ASR subscales plus ASR Total score (ranging from .07 to .64), and with the RI (.82). Novaco (1994) reported posi- tive correlations with both the Spielberger (1980) State/C0trait Anger Scale or STAS (.84), and the BDHI (.84), respectively. Mills et al. (1998) reported that the NAS and PI correlated positively with the BPAQ (.79 and .68, respectively). Cornell et al. (1999) reported that the NAS correlate .63 with the PI, and that both the NAS and PI correlated positively with the Spielbeger STAXI scales (ranging from .26 to .90), except for the STAXI Anger Control scale. Lindqvist et al. (2005) reported positive correlations between the NAS Total and Swedish adapta- tions of the BPAQ (.86) and the STAXI-2 (.79). Baker et al. (2008) reported a positive correlation of .69 between both components of the NAS-PI and STAS, and BDHI, respectively. Divergent/Discriminant As evidence of divergent/discriminant validity, Biaggio (1980, p. 296) reported that the NAS correlated negatively ( /C0.26) with the Marlowe-Crowne Social Desirability Scale. Subsequently, Biaggio et al. (1981) also85 MEASURES REVIEWED IN DETAIL II. EMOTIONAL DISPOSITIONS
reported that the NAS exhibited negli gible correlations (ranging from /C0.15 to .02) with the Personal Incidents Record. Novaco (1994) reported that NAS-PI scores were pred ictive of STAS and staff ratings of anger. Cornell et al. (1999) reported negative corre lations between the STAXI Anger Control and NAS (/C0.46), and PI ( /C0.21), respectively. Hornsveld et al. (2011) reported negligible or negative correlations between the NAS-PI and the Psychopathy Checklist-Rev ised (PCL-R). As further evidence of discriminant validity, Hornsveld et al. (p. 941) noted the lack of significant correlations between the NAS-PI and PCL-R t o t a ls c o r e ,a sw e l la san e g a t i v ec o r r e l a t i o n( /C0.29) between the NAS total score and PCL-R Interpersonal scale, and ( /C0.25) between the PI total score and PCL-R Affect ive scale. The NAS-PI was found to discrimi- nate between outpatients referred for anger management versus normal healthcare employees, as well as between forensic psychiatric patients versus normal secondary school vocational students ( Hornsveld et al., 2011 ). Construct/Factor Analytic As evidence of construct/factor analytic validity, Jones et al. (2003) , using the NAS-PI (1994 version), carried out an exploratory factor analysis ( N5566) that produced three factors, but these did not line up with those Novaco (1994) had suggested previously. Monahan et al. (2001) undertook an exploratory factor analysis (N51101) that failed to produce the expected factor structure. Novaco (2003) reported the results of an explor- atory factor analysis based on the national standardization sample ( N51546) which also failed to find the expected factor structure. Lindqvist et al. (2003) (NAS-PI, 1998 version; N5100) also failed to find the factor structure claimed by Novaco (1994) .Hornsveld et al. (2011) conducted a confirmatory factor analysis on the combined patient sample ( N5336) but could not find support for Novaco’s (1994) proposed three subscale structure ( χ2/df52.38, GFI 5.73, CFI 5.78, RMSEA 5.06). Hornsveld et al. also carried out a CFA on the stu- dent sample ( N5320) but again failed to confirm the three subscales ( χ2/df51.93, GFI 5.76, CFI 5.73, RMSEA 5.05). Thus, the putative tripartite structure of the NAS (cognitive, behavioral, and arousal factors) could not be confirmed. Criterion/Predictive As evidence of criterion/predictive validity, Novaco (1994) reported that the NAS significantly predicts mea- sures of aggressive behavior from hospital records and staff ratings as well as predicting the number of convic- tions for violent crimes ( Cornell et al., 1999 ). Likewise, Doyle and Dolan (2006) reported that among 112 violent offenders ( M540 years, SD511.5) whom had been released into the general community, measures of risk including the NAS significantly predicted future violent episodes.

Results and Comments The NAS-PI appears to provide a useful measure of affective, cognitive, and behavioral components of anger/hostility/aggression. Nonetheless, most f actor analytic studies have failed to find support for Novaco’s (1994) proposed three subscale structure. Even Novaco’s (2003) own factor analysis using the large national stand ardization sample ( N51646) failed to confirm the purported three-dimensional struc- ture. We can only conclude that, despite the great po pularity of the NAS-PI, its construct validity remains in doubt. NAS-PI SAMPLE ITEMS Scale Sample items Part A ‘Every week I meet someone I dislike’ ‘When I get angry, I get really angry’ ‘I can walk away from an argument’86 4. ANGER/HOSTILITY MEASURES II. EMOTIONAL DISPOSITIONS
Part B ‘Being criticized in front of other people for something that you have done’ ‘You are overcharged by someone for a repair’ ‘You are carrying a hot drink, and someone bumps into you’ Instructions : The statements in Part A are rated in terms of whether or not they apply to the subject: (1) never true; (2) sometimes true; or (3) always true. The statements in Part B are rated in terms of how angry they would make the subject feel, using a 4-point scale from ‘Not at all Angry’ to ‘Very angry’. Multidimensional Anger Inventory (MAI) (Siegel, 1985, 1986 ). Variable The multidimensionality of anger/hostility had been operationalized in some of the instruments discussed above (e.g., the BDHI, BPAQ, and NAS-PI). However, a more comprehensive representation of the multidimen- sionality of the anger/hostility construct has been proposed ( Siegel, 1986 ). Description The MAI is a 38-item rationally constructed multidimensional measure with several items assembled, and adapted from previously published measures such as the BDHI. The MAI is purported to measure multiple dimensions of anger, including Frequency, Duration, and Magnitude of anger responses, Mode of expression (Anger-in and Anger-out), Hostile outlook, Range of anger-eliciting situations, Guilt, Brood, and Anger-discuss. As with the NAS, RI, and ASR, a range of provocative anger-eliciting situations is incorporated into the MAI. Responses are on a 5-point Likert-type rating scale. Sample Initial samples included 198 college students (74 males; 124 females) and 288 male factory workers ( M554.8 years, range 40 /C063 years). Also, a separate sample of factory workers ( N5288) was utilized in Siegel’s (1986) study. Musante et al. (1989) utilized a sample of 82 male college students ( M/C2520 years), and 50 male faculty, staff and senior students ( M/C2540 years). Kroner, Reddon, and Serin (1992) investigated the structure of the MAI using a sample of 372 violent male prisoners. Reliability Internal Consistency Siegel (1985) reported Cronbach alpha coefficients for the five MAI components ranging from .51 to .85 (cf.Musante et al., 1989 ). Subsequently, Siegel (1986) reported an alpha coefficient of .84 for the MAI Total score in a college student sample ( N5198), and .89 in a sample of factory workers ( N5288). Aside from the Anger- out scale, for the combined sample ( N5486), all scales exhibited alpha coefficients ranging from .70 to .88 (Siegel, 1986 ). For the sample of college students alpha coefficients ranged from .63 to .84, while for the sample of factory workers, aside from the Anger-out scale, alphas ranged from .71 to .89. Test/C0Retest Siegel (1986) reported a stability coefficient of .75 over a 3 /C04 week test /C0retest interval based on a subsample of 60 college students. Validity Convergent/Concurrent As evidence of convergent/concurrent validity, Siegel (1986) reported that the five MAI components (see below) correlated positively with the Harburg inventory, as well as with the BDHI and NAS measures. For example, positive correlations with the BDHI Hostility subscale were as follows: MAI Anger-arousal (.49), MAI Range of anger-eliciting situations (.39), MAI Hostile outlook (.34), and MAI Anger-in (.62). Siegel (p. 198)87 MEASURES REVIEWED IN DETAIL II. EMOTIONAL DISPOSITIONS
also reported that the Spielberger STAI A-Trait scale correlated positively with MAI Anger-arousal (.54), with MAI Anger-in (.54), with Anger-eliciting situations (.29), and with Hostile outlook (.26), respectively. Also, the MAI Range of anger-eliciting situations correlated positively (.59) with the conceptually similar NAS items. Divergent/Discriminant As evidence of divergent/discriminant validity, Siegel (1986) reported negligible or negative correlations between the MAI Anger-out component, and other measures of anger, as follows: Harburg Duration (.06), Harburg Magnitude (.09), Novaco Magnitude (.06), Novaco Situations (.07), BDHI Hostility ( /C0.03), Harburg Anger-in ( /C0.10), and Harburg Anger-out (.20), respectively. In addition, Riley and Treiber (1989) , reported that the MAI Anger-out/Brooding scale which ‘assesses overt expression of anger combined with feelings of guilt and brooding related to the response’ (p. 400) correlated negatively ( /C0.46) with the Framingham Anger-in mea- sures of anger suppression. Construct/Factor Analytic As evidence of construct/factor analytic validity, Siegel (1986) carried out a principal components analysis with varimax rotation on the MAI item intercorrelations in two samples ( Ns5198 and 288). For the college sam- ple, three components were extracted and labeled: Anger-arousal (64% of the variance), Range of anger-eliciting situations (24% of variance), and Hostile outlook (12% of variance). For the combined sample ( N5486), no fewer than five separate components emerged and were labeled as follows: Anger-arousal (comprising: frequency, mag- nitude, and duration of responses), Range of anger-eliciting situations, Hostile outlook, Anger-in, and Anger-out, respectively. In a study of four well-established anger/hostility scales (BDHI, ASR, NAS, and MAI), Musante et al. (1989) carried out a second-order principal components analysis with varimax rotation ( N5132) of the 21321 subscale intercorrelations. Although five components exhibited eigenvalues greater than 1.0, on the basis of the Scree test ( Cattell, 1978; Cattell & Vogelmann, 1977 ), Musante et al. chose to extract only three higher-order components that were labeled: Experience of Anger (‘representing anger-arousing and -eliciting situations and anger awareness’); Expression of Anger (‘either physical assault or verbal expression of anger’) and Suspicion- Guilt (‘suspicion, mistrust-suspicion, and guilt’), respectively. Riley and Treiber (1989) found that they were unable to replicate the multi-factorial structure put forward by Siegel (1986) . Likewise, Kroner et al. (1992) also investigated the factor structure of the MAI in a sample of 372 violent male prisoners, but claimed support for only a two-factor structure, despite the previously demonstrated and cross-validated multidimensionality of the MAI measure. Kneip et al. (1993) using a sample of coronary heart disease patients, reported a two-factor struc- ture for the MAI. Using a large Finnish sample, Miller, Jenkins, Kaplan, and Salonen (1995) reported the results of a CFA that supported the MAI rationally devised dimensions rather than the claimed multifactorial structure. However, Dutton (1995) found support for the following MAI subscales: Anger-in, Anger-out, Magnitude of anger, and Frequency of anger. Criterion/Predictive As evidence of criterion/predictive validity, the MAI Hostile Outlook scale correlated positively (.46) with the sum of the BDHI Negativism, Resentment, and Suspicion scales ( Siegel, 1985 ).Musante et al. (1989) reported that scores on the Structured Interview (SI) Potential for Hostility were significantly predicted by MAI Anger-Arousal (.34), MAI Hostile outlook (.25), and MAI Range of eliciting conditions (.33), respectively (the predictive correla- tions for MAI Anger-in and Anger-out were quite low, being .14 and 18, respectively).

Subsequently, Musante et al. (1989) concluded that these anger measures reflect emotional, interpersonal, and attitudinal components, which can be defined in terms of an experiential anger dimension, an anger expression dimension, and a hostile or88 4. ANGER/HOSTILITY MEASURES II. EMOTIONAL DISPOSITIONS
suspicious-mistrustful attitudinal outlook dimension. Siegel (1986) pointed to these findings as evidence for ‘con- ceptualizing anger as a multidimensional construct.’ (p.198). However, doubts remain as to the factor structure of the MAI, and in addition, Eckhardt, Norlander, and Deffenbacher (2004) warned that, ‘given the weak psycho- metric support for the anger expression items, it does not appear that the MAI offers an unambiguous assessment of anger expression style’ (p. 28). Another caveat is that the relevance of MAI hypothetical anger provocations to violent offenders may be questionable. This, as we shall see is a recurring theme in examining the utility of mea- sures of anger when it comes to predicting criminal violence. MAI SAMPLE ITEMS Scale Example item Frequency ‘Something makes me angry almost every day’ Duration ‘When I get angry, I stay angry for hours’ Magnitude ‘I often feel angrier than I think I should’ Hostile Outlook ‘Some of my friends have habits that annoy me very much’ Anger-in ‘I harbor grudges that I don’t tell anyone about’ Anger-Out ‘When I’m angry with someone, I let that person know’ Range of Anger-Eliciting Situations ‘I get angry when something blocks my plans’ Note. Items are rated on a 5-point Likert-type scale ranging from: ‘Completely undescriptive’ to ‘Completely descriptive’. State/C0Trait Anger Expression Inventory /C02nd Edition (STAXI-2) (Spielberger, 1988, 1991, 1999 ). Variable The distinction between trait and state constructs has been promoted especially by Spielberger’s construction of various state /C0trait scales/measures. The anger construct can also be viewed in terms of state and trait aspects. However, as pointed out in Chapter 8 on Measures of Affect Dimensions by Boyle, Helmes, Matthews and Izard, there are indeed many possible forms of affect constructs ranging all the way from transient/fleeting emotional states, through longer lasting mood states, through motivational dynamic traits, to relatively stable enduring per- sonality traits. While dichotomous state and trait constructs may be useful in some circumstances, there are actu- ally many different forms of anger affect that lie somewhere on the continuum in-between these two polar extremes that also require measurement (e.g., see Chapter 8; Davey & Day, 2007 ;Fernandez, 2008 ;Fernandez & Kerns, 2008 ). Description The STAXI-2 ( Spielberger, 1999 ) which is purported to measure the experience, expression, and control of anger, consists of 57 items, 6 scales, 5 subscales, and an Anger Expression Index (total anger expression) (cf.Spielberger & Reheiser, 2009 ). The State Anger scale (15 items) measures anger intensity as a momentary emotional state, while the Trait Anger scale (10 items) measures the disposition to experience angry feelings as a personality-like trait over lengthy time periods (i.e., the individual’s disposition to become angry or angry tem- perament). The Anger Expression scale (16 items) and the Anger Control scale (16 items) measure four anger- related trait dimensions. As Vagg and Spielberger (2000) in their Interpretive Report (STAXI-2: IR t) indicated, the Anger Expression-In scale measures the extent to which an individual ‘holds things in’ or suppresses anger, whereas the Anger Expression-Out scale measures the actual expression of aggression. Concomitantly, the Anger Control-In scale measures the extent to which an individual controls the expression of anger through attempts at relaxation and ‘calming down’, whereas the Anger Control-Out scale measures the extent to which an individual actively monitors and limits the overt expression of anger. As stated on the Mingarden website (see link below), ‘Scales include: State Anger, Trait Anger, Anger Expression-Out, Anger Expression-In, Anger Control-Out, Anger89 MEASURES REVIEWED IN DETAIL II. EMOTIONAL DISPOSITIONS
Control-In, and Anger Expression Index .’ Ratings of items are on a 4-point response scales that measure state anger (intensity) as well as trait anger (frequency). Software for Windows sis available that permits an unlimited num- ber of scoring and interpretive reports. Sample Spielberger and Reheiser (2004) reported that: ‘The normative samples for the STAXI-2 are based on the responses of more than 1900 individuals from two populations: a hetero- geneous sample of 1644 normal adults (977 females, 667 males) and 274 hospitalized psychiatric patients (103 females, 171 males). The sample of normal adults included managerial, technical, and clerical personnel: participants in stress management programs; health care managers and professionals; insurance company employees; and undergraduate and graduate students enrolled in a large urban university’. (p. 78) Borteyrou, Bruchon-Schweitzer, and Spielberger (2008, 2014) utilized a large French sample of 1085 respon- dents (539 males; 546 females; aged 18 to 70 years) in validating a French adaptation of the STAXI-2. In addition, for the STAXI-2 C/A, the normative sample consisted of 836 individuals ( M513.77 years, SD52.54) ( Brunner & Spielberger, 2009 ). Reliability Internal Consistency Spielberger (1999) reported Cronbach alpha coefficients for the STAXI-2 scales ranging from 0.73 to 0.93 (Spielberger, 1999 ). In a sample of Hispanic undergraduates, Culhane and Morera (2010) reported alpha coeffi- cients of 0.70 or higher. Cornell et al. (1999) reported alpha coefficients as follows: State Anger (.91), Trait Anger (.90), Anger-In (.63), Anger-Out (.80), and Anger Control (.82). Spielberger and Reheiser (2004) reported alpha coefficients based on the STAXI-2 normative sample ( N.1,900) ranging from .73 to .95 (Mdn 5.87), with alphas for the AX index ranging from .75 to .82. For the STAXI-2 C/A, Brunner and Spielberger (2009) reported alpha coefficients ( N5838) as follows: Trait Anger scale (.80), State Anger scale (.87), Anger Expression-Out (.70), Anger Expression-In (.71), and Anger Control (.79). In a clinical sample ( N552), the corresponding alphas were: Trait Anger scale (.88), State Anger scale (.94), Anger Expression-Out (.84), Anger Expression-In (.74), and Anger Control (.89). Test/C0Retest For the French adaptation of the STAXI-2, Borteyrou et al. (2008) reported that over a two-month interval (N5139), stability coefficients were .70 for the trait anger scale and .32 for the state anger scale, respectively. Validity Convergent/Concurrent As evidence of convergent/concurrent validity, correlations between the STAXI trait anger and the Cook and Medley (1954) Ho scale ranged from .43 to .59, and those between the STAXI with the BDHI total score ranged from 0.66 to 0.73. Cornell et al. (1999, Table 1) reported positive inter-correlations between all of the STAXI sub- scales (except STAXI Anger Control). Cornell et al. also reported positive correlations between the NAS and the STAXI scales as follows: STAXI State Anger (.39), STAXI Trait Anger (.90), STAXI Anger-In (.43), STAXI Anger- Out (.76), as well as positive correlations with the Novaco PI as follows: STAXI State Anger (.30), STAXI Trait Anger (.63), STAXI Anger-In (.26), and STAXI Anger-Out (.49), respectively. For the STAXI-2 C/A, in the norma- tive sample, positive correlations were found between the scales and subscales (except for Anger Expression-In and Anger Control) ranging from .29 to .90 ( Brunner & Spielberger, 2009 ). Divergent/Discriminant As evidence of divergent/discriminant validity, Deffenbacher et al. (1996) [as cited in Eckhardt et al. 2004 ] found that Trait Anger scores ‘correlated more highly with other anger-related constructs than with measures of anxiety, depression, intoxication, phobic anxiety, paranoid thinking, and psychoticism’ (p. 29) thereby providing support for divergent/discriminant validity. Also, Cornell et al. (1999) reported negative correlations between the STAXI Anger Control subscale and each of the other STAXI subscales (ranging from /C0.09 to/C0.49). As further evi- dence of discriminant validity, Cornell et al. reported negative correlations between the Novaco NAS and STAXI Anger Control ( /C0.46), and between the Novaco PI and STAXI Anger Control ( /C0.21), respectively. For the90 4. ANGER/HOSTILITY MEASURES II. EMOTIONAL DISPOSITIONS
STAXI-2 C/A, in the normative sample, negative correlations were found between both the Anger Expression- In/Anger Control scales and the respective State and Trait scales/subscales ranging from -.03 to -.28 ( Brunner & Spielberger, 2009 ). However, the STAXI-2 “was vulnerable to social desirability response bias…” ( McEwan, Davis, MacKenzie, & Mullen, 2009, p. 431 ). Construct/Factor Analytic As evidence of construct/factor analytic validity, Fuqua et al. (1991) carried out a principal-axis factor analysis with varimax rotation ( N5455 undergraduates) of the item intercorrelations for the 44-item STAXI, providing support for the purported factor structure of the measure. Likewise, Forgays, Forgays, and Spielberger (1997) as well as Forgays, Spielberger, and Forgays (1998) provided factor analytic evidence supporting the claimed STAXI structure. Maxwell, Sukhodolsky, and Sit (2009) reported CFAs on the STAXI-2 item intercorrelations for two Hong Kong samples ( N5489 and 775) providing support for the claimed factor structure. In a Swedish under- graduate sample ( N5100), Lindqvist et al. (2003) found some support for the purported STAXI-2 factor structure. De la Rubia, Gonza ´lez, and Landero (2010) reported both a principal components analysis with oblique promax rotation and a confirmatory factor analysis of the STAXI-2-AX item intercorrelations in a sample of 226 Mexican housewives, finding support for the purported factor structure. Borteyrou and Bruchon-Schweitzer (2014) con- ducted both EFA and CFA analyses of the STAXI-2 item intercorrelations on a large French sample of 1085 respondents (539 males; 546 females; aged 18 to 70 years), and reported that they could only reproduce three of the purported STAXI-2 factors. Criterion/Predictive As evidence of criterion/predictive validity, Spielberger and Reheiser (2010) stated that, suppressed anger, as measured by the Anger-In subscale of the STAXI is a key factor in hypertension (e.g., Johnson, Spielberger, Worden, & Jacobs, 1987 ;van der Ploeg, van Buuren, & van Brummelen, 1988 ). The STAXI has also been used in studies of hardiness, well-being, and coping with stress ( Schlosser & Sheeley, 1985 ); anger in patients treated for Hodgkin’s disease and lung cancer ( McMillan, 1984 ); Type A behavior ( Booth-Kewley, & Friedman, 1987 ); the effects of marijuana use ( Pape, 1986; Stoner, 1988 ); and chronic pain ( Curtis, Kinder, Kalichman, & Spana, 1988 ). Likewise, Antypa et al. (2013) reported that STAXI Anger-Out scores significantly predicted ‘anger expressed out- wards ...in male suicidal patients compared to controls ( p,.001)’ (p. 393). Also, Desche ˆnes, Dugas, Fracalanza, and Koerner (2012) reported that the STAXI-2 significantly predicted generalized anxiety disorder severity. Coates and Pretty (2003) reported that the STAXI-2 Trait Anger and Anger-Out scales significantly predicted future arthritic health status. Location Spielberger, C.D.

Results and Comments As a successor to the STAXI, the STAXI-2 has had a slower rate of application in anger research, but it is the currently preferred version. The instrument has been translated into Spanish ( Miguel-Tobal, Casado, Cano- Vindel, & Spielberger, 2001 ) and adapted for use in Mexico (e.g., Alca´zar, Deffenbacher, & Byrne, 2011 ). With the earlier theoretical caveats in mind, STAXI-2 results can be used to ascertain whether an individual’s anger is pri- marily attributable to frustration or perceived maltreatment (as in state anger) or whether it is an indication of premorbid anger-proneness (or trait anger). Even when the overt expression of anger (Anger-out) is minimal, the STAXI-2 can capture anger that may be present where Anger-in scores are high. A person’s handling of anger can lie between overcontrol and undercontrol and the STAXI-2 can help locate that point for purposes of treat- ment planning.91 MEASURES REVIEWED IN DETAIL II. EMOTIONAL DISPOSITIONS
MEASURES REVIEWED BRIEFLY The Anger Disorders Scale (ADS; DiGiuseppe & Tafrate, 2004 )/C0(not to be confused with the Anger Discomfort Scale to be described later) was introduced as one of the more clinically-relevant measures for assessing anger. The ADS consists of five domains and 18 subscales as follows: The Provocations domain includes (i) scope of anger provocations and (ii) hurt/social rejection; the Arousal domain includes (i) physiological, (ii) duration, and (iii) episode length; the Cognitions domain includes (i) suspicion, (ii) resentment, (iii) rumination, and (iv) impulsivity; the Motives domain includes (i) tension reduction, (ii) coercion, and (iii) revenge; the Behaviors domain encompasses (i) anger-in, (ii) physical aggression, (iii) verbal expression, (iv) indirect aggression, (v) pas- sive aggression, and (vi) relational aggression. Subscale scores can be plotted as coordinates on a graph. The ADS has been administered as a structured interview with 134 questions to be rated on a 5-point Likert-type response scale ( Ahmed, Kingston, DiGiuseppe, Bradford, & Seto, 2012 ). Items are framed as questions with multi-choice answers. For example, ‘My anger has been a problem for (i) ‘a week or less or not at all’, (ii) ‘a month or less’, (iii) ‘About three months’, (iv) ‘About six months’, (v) ‘A year or more’; or ‘I get angry if someone makes me look bad in front of others’ which is accompanied by the following options for answers: (i) ‘never’, (ii) ‘rarely’ (iii) ‘occasionally’, (iv) ‘often’, (v) ‘always’. The ADS was normed on a sample of over 1400 American adults (aged 18 /C076 years) recruited from educational and work environments as well as the internet. Test /C0retest reli- ability based on a college sample ( N565) was found to be .89 over a two week interval. A Short Form of the ADS with three subscales (expression, anger-in, and vengeance) is also available. With 18 subscales to the ADS, the number of possible profiles in which half of the subscales are elevated approaches 50,000; this number exceeds 250,000 when all possible combinations are considered. As an alternative, a Short Form with three subscales (expression, anger in, and vengeance) may be used. TheAnger Parameters Scale (APS; Fernandez, 2001 ;Fernandez et al., 2010 ) was constructed in light of the frequent distinction drawn between experience versus expression of anger and the further differentiation among subtypes of anger experience and anger expression, Fernandez (2001) developed two separate scales: the Anger Parameters Scale (APS) and the Anger Expressions Scale (AES). As it stands, the latter is a theoretical formulation undergoing empirical evaluation, so the present focus is on the APS. In the APS, five anger parameters were operationalized to delineate boundaries of anger activity: frequency, duration, intensity, latency, and threshold. The first three were already subscales within the MAI and they have also been dependent measures in behavioral psychology. However, as with pain and other perceptual responses, the occurrence of anger can also be measured in terms of latency and threshold (Fernandez, 2010). Thus, we have five parameters measuring (i) how often one gets angry, (ii) how long the anger lasts, (iii) how strong the anger is, (iv) how quick to anger, and (v) how sensitive to provoca- tion. This is in keeping with affective chronometry for measurement of emotions ( Davidson, 1998 ) and the notion of an emotion-generative process ( John & Gross, 2007 ). The 30 APS items, some of which are negatively-keyed are organized into six items per parameter. Each item is rated on a 5-point Likert-type response scale reflecting the extent to which the items are applicable to the individual test-taker. The APS has been administered to an adult community sample ( Fernandez et al., 2010 ). Cronbach alpha coefficients were found as follows: Frequency (.85), Duration (.90), for Intensity (.62), Latency (.88), and Threshold (.74) ( Fernandez et al., 2010 ). A principal components analysis with oblique rotation led to the extraction of five components conforming to the five different parameters of anger ( Fernandez et al., 2010 ). A separate PCA analysis based on the subscale inter-correlations led to a one- component solution which the authors termed the Degree of maladaptiveness of anger. More recently the APS was administered to a sample of incarcerated adults ( Fernandez et al., 2014 ) who showed elevations on frequency, duration, and intensity (but not threshold or latency) as compared to adult counterparts from the community. In summary, the APS accesses five basic parameters applicable to emotions or affective phenomena, independently of how anger is qualitatively expressed. The parameters are internally consistent and supported by preliminary fac- tor analytic investigation. Some examples of items include: ‘I seldom get angry’ (Frequency), ‘I stay angry only for a short time’ (Duration), ‘It takes very little to make me angry’ (Threshold), My anger takes the form of annoyance’ (Intensity), and ‘My anger occurs immediately’ (Latency). The Awareness and Expression of Anger Indicator (AEAI; Catchlove & Braha, 1985 ) attempts to assess Awareness of feelings of anger as well as the Expression of anger. The AEAI uses one hypothetical vignette which is read out to the individual who is asked two questions, one about how s/he feels, and the other about what s/he would do. The individual is then told to imagine that the same scenario occurs on four successive mornings. Again, s/he is asked the same two questions about feeling and expression of anger. Answers to these questions are ranked with reference to the idealized response for each occurrence of the scenario. Based on a sample of 30 pre-surgical patients an inter-rater reliability of 0.94 was obtained. Overall, no significant correlation between92 4. ANGER/HOSTILITY MEASURES II. EMOTIONAL DISPOSITIONS
awareness and expression of anger was observed. The AEAI is unique in its use of a single vignette, a very small sample, and partly qualitative analyses of data. The last of these makes the AEAI worthy of consideration as an adjunct to the standard quantitative rating scales used in anger assessment. The sole item consists of a hypotheti- cal vignette as follows: ‘You have a regular arrangement with a friend to pick you up every morning at 08:15 to go to work. He arrives at 08:35 a.m.’ (Catchlove & Braha, p. 114). The Standardized Experience of Anger Measure (STEAM; Linden et al., 1997 ) was developed by Linden et al. (1997) a measure of situation-specific anger who pointed out that the STAXI and most measures of anger opera- tionalize anger as a trait construct. The authors of the STEAM generated a pool of 54 vignettes that contained at least two of the following theorized components of anger: damage, intent, and preventability. Individuals employed a 10 cm visual analogue scale to rate each vignette in terms of (i) degree of anger aroused by the described situation; (ii) suitability of the vignette for different populations; and (iii) clarity of the vignette. Setting high cutoffs on each of these criteria, a total of 12 vignettes emerged as usable for both students and the general community. Thirty-one fellow students, friends, and family members comprised the sample used in this study. Cronbach alpha coefficients were found to be 0.89 for college students and 0.88 in a community sample. Test/C0retest reliability at one-month was found to be 0.83. Although significant, correlations were low between the STEAM and the trait anger and anger-out scores on the Spielberger STAXI/STAXI-2 scales. This suggests that the former is measuring something slightly different from the latter. The STEAM makes a good attempt to orga- nize vignettes according to attributional theories of anger. It has acceptable reliability though factorial validity remains to be evaluated. An example of the 12 vignettes is: ‘Your friends ask you to babysit their 10-year-old child for the evening. You have an important report for work that must be completed by morning, so you will need quiet time to work while the child is sleeping. You try to explain this to the child, but s/he continues to be loud and disruptive well beyond his/her normal bedtime. How anger-arousing is this situation?’ The Anger Control Inventory (ACI; Hoshmand & Austin, 1987 ) is based on a model of cognitive-behavioral and person-situation interactions. This inventory began with 134 items, organized into 10 anger stimulus scales and six anger response scales. Item retention was based on inter-judge agreement. The stimulus scales comprised (i) seeing others abused, (ii) intrusion, (iii) personal devaluation, (iv) betrayal of trust, (v) minor nuisance, (vi) external control and coercion, (vii) verbal abuse, (viii) physical abuse, (ix) unfair treatment, and (x) goal-blocking. The response scales were (i) behavioral which was further differentiated into destructive or passive responding versus constructive or assertive responding, (ii) cognitive which was differentiated into maladaptive cognition and cognitive skill deficit, and (iii) arousal differentiated into duration and intensity. Two samples of 118 clinical clients and 190 undergraduate students were used in the initial studies, respectively. Hoshmand, Austin, and Appell (1981) reported Cronbach alpha coefficients (ranging from .54 to .81) for the stimulus scales and .76 to .89 for the response scales. One-month retest reliability ranged from (.72 to .83) for the stimulus scales and (.73 to .83) for the response scales. When normals were compared with batterers seeking treatment, significant differences appeared in the expected direction for four of the stimulus scales and five of the response scales. Factor analysis of the 16 scales lent support to the presence of an Anger Stimulus and an Anger Response Scale ( Hoshmand & Austin, 1987 ). For a sample of patients, therapist rat- ings of anger difficulties were significant but low-to-moderate in their correlation with stimulus scales or response scales. However, this issue of criterion validity is an important one that has been largely neglected in the anger assess- ment literature. This inventory is well-conceived in terms of its broad division between stimulus and response scales, and the further subdivision of the former into common types of anger elicitors. The Anger Discomfort Scale (ADS; Sharkin & Gelso, 1991 )shares the same acronym as the Anger Disorders Scale, but assesses something quite different: a person’s degree of intrapersonal and interpersonal discomfort with anger. In that sense, it is associated with anger suppression. Respondents simply rate each of the 15 items on a 4-point response scale ranging from ‘Almost never’ to ‘Almost always’. The ADS was administered to 150 undergraduates and was found to exhibit a Cronbach alpha coefficient of .81 and a test /C0retest reliability coeffi- cient of .87. ADS scores correlated significantly and mostly with anger-in, less so with anger-out, and negatively with anger control on the STAXI/STAXI-2. A principal axis factor analysis led to retention of four factors labeled: intrapersonal discomfort with one’s own anger, positive views of anger, interpersonal discomfort with anger, and perceived concomitants of anger. Koo and Park (1998, p. 60), reported that when the ADS was administered to male and female counselor trainees, high scores were predictive of state anxiety. The ADS can be a particularly useful tool in screening participants for readiness and motivation to enter into anger treatment programs. Here are some examples of the 15 items making up the ADS: ‘I do not like it when I get angry’, ‘I believe that it is nat- ural and healthy to feel angry’, ‘I create more problems for myself when I get angry’.93 MEASURES REVIEWED BRIEFLY II. EMOTIONAL DISPOSITIONS
TheAnger Readiness to Change Questionnaire (ARCQ; Williamson et al., 2003 ) measures readiness to change among those identified as in need of intervention to manage problematic anger. The Transtheoretical Stages of Change model ( Prochaska & DiClemente, 1984, 1986 ), one of the most influential models of behavior change, was originally developed to describe the process of behavior change for addictive behavior, and postulates that individuals pass through a series of stages involving a series of different processes when attempting to change their behavior. The ARCQ scale is an adaptation of the Readiness to Change Questionnaire (RCQ; Heather & Rollnick, 1993) designed to identify stages of change among problem drinkers. The 12-item measure incorporates the original RCQ items modified to measure stages within the context of anger problems by changing the wording of each item from alcohol to anger (e.g., ‘Sometimes I think I should try and control my anger’). The questionnaire has four items to assess three stages of change; pre-contemplation, contemplation, and action. Responses are made on 5-point Likert- type response scale scored from /C02 (strongly disagree) to 12 (strongly agree), with total scores for each scale calcu- lated by summing the relevant item scores. Possible scores range from /C08t o18 on each scale. The authors recom- mend a method of scoring (stage allocation) which classifies only participants with meaningful patterns of scores over the three ARCQ scale scores. Patterns showing high (or low) scores on all three scales, or high scores on both pre-contemplation and action but low on contemplation, represent non-meaningful patterns. An allocation to the pre-contemplation stage, for example, will occur when a person scores a positive score on the pre-contemplation scale, but a negative (or zero) score on both the contemplation and action scales. Some 418 adult male convicted prisoners located in 16 different prisons in two states of Australia were recruited for a project evaluating anger man- agement programs. The mean age of the sample was 28.75 years (range 518 to 62 years). Of the 411 participants who indicated ethnicity, 266 (64.7%) classified themselves as Australian/New Zealander, 77 (18.7%) as Australian Aboriginal, 40 (9.7%) as European, 10 (2.4%) as Asian, and 18 (4.4%) as other. The majority ( N5237) were single (58.8%), with 123 married/defacto (30.5%), and the remainder (10.7%) divorced/widowed. Most were unskilled/ unemployed ( N5226, 58.7%), with 140 (36.4%) semi-skilled/tradesmen, and 19 professionals. Over half the sample (N5223, 62.1%) reported current offences that included violence. Sentences being served ranged from 1 month to 26 years ( M550.0 months, SD559.0), with 137 (41.5%) first time offenders with mean number of previous offences 2.98 (ranging from 1 to 14 offences) among repeat offenders. The Cronbach alpha coefficient for the pre- contemplation scale was (.58), for the contemplation scale (.79), and for the action scale (.78). Internal consistency was enhanced when pre-contemplation items were reverse coded ( α5.82). The semi-structured interview of treat- ment readiness developed by Serin (1998) and Serin and Kennedy (1997) was adapted for use as a brief 11-item questionnaire, named the Treatment Readiness Scale (TRS). Correlations between this measure and the pre- contemplation, contemplation, and action subscales were /C0.33, .50, and .55 respectively. Three factors corresponding to the pre-contemplation, contemplation, and action stages were reliably identi- fied. However, a CFA also showed that two contemplation items were loaded moderately by both the contempla- tion and action factors. The final measurement model resulted in the addition of two extra pathways from the action latent variable to two contemplation items. This model showed an improved model fit ( χ2 (49)5266.4, p,.001; GFI 50.91; NNFI 50.86). There was support for the hypothesis that treatment was more beneficial in reducing anger when ARCQ scores were initially high; either high total scores or classification to higher stages (i.e., contemplation, preparation, action). The interaction between group and readiness to change was tested using moderated multiple regression. The variables combined explained a significant 4.1% of the variance in standard- ized anger change scores (F (2,271)55.78, p5.004). Only readiness to change was a significant predictor of anger change (readiness to change, β5/C0.20; group, β5/C0.02). The ARCQ may be a useful tool for selecting participants for anger management programs. It may also help to identify when alternative interventions are required for those who are less ready for anger management. Sample items include: ‘Controlling anger better would be point- less for me’ (Pre-contemplation); ‘I’m entitled to get angry, but sometimes I go too far’ (Contemplation); ‘Anyone can talk about wanting to do something about anger, but I am actually doing something about it’ (Action). The Short Anger Measure (SAM; Gerace & Day, 2014) measures angry feelings and aggressive impulses. The SAM is a 12-item self-report measure of angry feelings and aggressive impulses. Originally developed for use as a brief measure of anger for use with adolescents identified as ‘at risk’, the SAM differs from trait measures of anger in that it asks respondents to rate their anger over the last week. It is intended for use as brief measure of anger for use in forensic populations which can be used for screening purposes before treatment is offered and to measure change in anger over time. SAM items were selected to address the frequency of the experience and of the expression of anger. Respondents are asked to answer on a 5-point Likert-type response scale from ‘Never’ to ‘Very often’ over the previous week. Sample items are ‘I felt angry’, ‘Something annoyed me and I couldn’t get it out of my mind’, ‘I felt like I was ready to explode’, ‘Other people or things got on my nerves’. Total scores on the SAM in the development study ranged from 12 to 58, with a mean score of 23.56 ( SD59.31).94 4. ANGER/HOSTILITY MEASURES II. EMOTIONAL DISPOSITIONS
Some 73 adult male offenders in both community and prison settings in South Australia participated in the devel- opment of the SAM. Of these 49 were in prison and 24 were in the community (reporting to a probation and parole or community corrections center). The average age of participants was 30.38 years ( SD58.55; Range519/C060 years) and the average level of education completed was Year 10. The full scale scores exhibited a high Cronbach alpha coefficient of .91 (cf. Boyle, 1991 ). A subgroup of participants completed the SAM twice over a two-week interval. The test /C0retest reliability coefficient (.74) suggested that the scores were relatively stable, but still amenable to change. Correlations between the total SAM score and the subscales of the State /C0trait Anger Expression Inventory-2 (STAXI-2, Spielberger, 1999 ) were used to assess concurrent validity. Scores on the total SAM score were moderately associated with those obtained from the Trait Anger subscale of the STAXI (.33), indicating that the SAM measures a construct that is related to trait anger. Scores were also moderately correlated with Anger Expression-Out (.58), Anger Control-Out ( /C0.52), and Anger Control-In ( /C0.39) scales of the STAXI-2, with weaker correlations between the measure and State Anger (.39) and Anger Expression-In (.26). Anexploratory Principal Axis Factoring with an oblimin rotation was used to assess the factor structure of the measure. Factor analysis identified two dimensions. The correlation between factors was high (.67) and the authors suggest that persons administering the measure should use a total scale score. This study suggests that the SAM may be a useful screening tool for problematic anger when only brief assessment is possible, and as an outcome measure in treatment evaluation or in assessing changes in anger over time. FUTURE RESEARCH DIRECTIONS The aim of this chapter was to provide an overview of some of the most widely used and emerging self-report measures of anger/hostility in adults. Even a cursory inspection of the 16 self-report measures reviewed in this chapter shows that in general they do live up to psychometric standards of reliability and validity and are conve- nient to administer and score. Where the substantive differences exist are in the particular construct of interest (e.g., anger or hostility, arousal versus expression of anger, and different subtypes of anger). The choice of which instrument to use is also dictated by the population of interest (e.g., community, psychiatric, forensic). As well, the selection of a scale/measure hinges on the specific question being posed, whether this be related to classifica- tion and diagnosis, case conceptualization, making decisions about the course and efficacy of treatment, or testing hypothesized relationships between anger and other aspects of health and human functioning. Nevertheless, some measures are lacking in data about test /C0retest reliability. Especially with state /C0trait mea- sures such as the STAXI-2, it would be expected that the trait scale would exhibit temporal stability whereas the state scale would exhibit much lower test /C0retest correlations, if it is truly sensitive to situational variability. Also, there are many different forms of anger and hostility ranging all the way from transitory emotional states, through longer lasting mood states, through motivational dynamic traits, and finally relatively stable enduring personality traits. One ongoing problem is the fact that self-report scales/measures (including those reviewed in this chapter) are prone to motivational and response distortion. Clearly, a range of factors may be responsible for biased responding, ranging all the way from deliberate conscious dissimulation to inadequate self-insight and/or lack of conscious awareness of one’s anger and hostility. Responses to items included in self-report measures of anger and hostility are easily distorted, and therefore, treatments and interventions based on scores from such scales need to be considered carefully. One avenue of possible advancement would be to develop objective (T-data) test measures of anger and hostility, in order to minimize the impact of such conscious or unconscious motivational biases in responding (cf. Boyle, Stankov, & Cattell, 1995, p. 435; Schuerger, 2008). A further ongoing problem for many of the self-report anger/hostility measures presented in this chapter, is that the application of factor analytic methods often leaves much to be desired. A recurring theme is the use of less than optimal factor analytic methods, particularly the now essentially outmoded principal components anal- ysis plus varimax (‘Little Jiffy’) procedure which, at best, produces somewhat crude approximations to the actual structure of the various measures (see Cattell, 1978 ). Likewise, use of varimax rotation can be problematic in arti- factually imposing orthogonality onto the components, when in fact, the components may be correlated in real life. Extracting and rotating components however, rather than factors, necessarily means that both measurement and unique error variance contaminates the resultant components. Nonetheless, advances in factor analytic meth- ods, including use of confirmatory factor analysis have already resulted in construction of new measures of anger and hostility some of which are described in this chapter.95 FUTURE RESEARCH DIRECTIONS II.

CHAPTER 5 Measures of Life Satisfaction Across the Lifespan Marco Weber, Claudia Harzer, E. Scott Huebner and Kimberly J. Hills University of South Carolina, Columbia, SC, USA The notion of life satisfaction or perceived quality of life has been of central importance to several areas of inquiry including gerontology, mental health, positive psychology, quality of life, and social indicators research. It is frequently used as a criterion measure in studies of the determinants of optimal well-being among adults and children ( Lyubomirsky, King, & Diener 2005 ). Studies have also suggested that it is not only an important psychological ‘outcome’, but it is also an important determinant of a variety of adaptive life outcomes, such as health, longevity, quality relationships, and vocational success ( Lyubomirsky et al., 2005 ). In addition to research applications, practical applications have been numerous as well, including clinical ( Frisch, 2006 ), school (Gilman & Huebner, 2003 ), and business ( Judge, Thoresen, Bono, & Patton 2001 ) settings. Diener (2000) has issued a call for nations to undertake the development of ongoing national indexes of well-being, including measures of life satisfaction as core indicators. Since Andrews and Robinson’s (1991) contribution to the last edition of this text, research on the measurement and correlates of life satisfaction and related variables has increased dramatically. This increase has included sub- stantial attention to a previously neglected population, that is, children and adolescents. Thus, research efforts are now being undertaken across almost the entire lifespan. Consistent with the review of Andrews and Robinson (1991) , the research continues to be ‘extensive, broad-ranging, and conceptually diffuse’ (p. 61). Despite this widespread use of the construct in research and practice contexts, challenges remain with its defi- nition, measurement, and interpretation. With respect to its definition, life satisfaction is often confused with pos- itive affect (aka ‘happiness’) as well as the absence of negative affect. These constructs are often used interchangeably in the literature, yet they are already differentiable (using factor analytic procedures) by children as young as age 8 years ( Huebner, 1991a ). On the one hand, positive affect refers to individuals’ experience of fre- quent positive emotions, such as joy, interest, and excitement, while negative affect refers to individuals’ experi- ence of frequent negative emotions, such as guilt, anxiety, and anger. On the other hand, life satisfaction is typically defined as a cognitive (vs. emotional) judgment of the positivity of one’s life as a whole and/or with specific life domains (e.g., family, work, school) ( Diener, 1994 ). In addition to being conceptually and statistically distinguishable, these constructs show different correlates and can diverge across time ( Diener, 1994 ). Furthermore, life satisfaction reports tend to be more reliable across time ( Diener & Larsen, 1984 ). Thus, the over- all conclusion from the extant body of research suggests that the constructs of life satisfaction and affect are related somewhat, but show considerable discriminant validity, indicating the need to measure them separately in studies of adult and child well-being and quality of life. Within the present chapter we will focus on this more cognitive element of well-being, that is, on the assessment of life satisfaction. Some measurement and interpretation issues also remain unresolved. Most measures of life satisfaction have been derived from one of three separate theoretical models. Some measures are based on a ‘bottom up’ model, in which a ‘general’ life satisfaction score is calculated by summing responses to a variety of domain-specific items (e.g., my family life is good, I enjoy going to work, school is fun). In some cases, weighted responses are deter- mined based on an individual’s judgment of the importance of the particular domain. An example of a ‘bottom 101Measures of Personality and Social Psychological Constructs. DOI: http://dx.doi.org/10.1016/B978-0-12-386915-9.00005-X ©2015 Elsevier Inc. All rights reserved.
up’ scale for adults is Frisch’s (1992) Quality of Life Inventory , and an example of such a scale for children is the Perceived Life Satisfaction Scale (Adelman, Taylor, & Nelson 1989 ). Other measures have been based on a ‘top down’ model, in which a ‘global’ life satisfaction score is deter- mined from one or more items that are domain-free in nature (e.g., my life is good vs. my family life is good). Such measures allow the respondents to formulate their responses based upon their own unique circumstances and standards ( Pavot & Diener, 1993 ). This approach contrasts with the aforementioned ‘general’ approach as well as the ‘multidimensional’ approach (see below) in which the items reflect content (e.g., nature and number of domain-based items) determined by the test developer. An example of the ‘global’ type of scales for adults is theSatisfaction with Life Scale (Diener, Emmons, Larsen, & Griffin 1985 ), and an example of a scale for children is theStudents’ Life Satisfaction Scale (Huebner, 1991b ). Finally, some measures of life satisfaction emphasize multidimensional assessments of specific life domains, which are considered to be important to most, if not all, individuals of interest. Such instruments thus yield pro- files of individuals’ life satisfaction judgments, providing greater emphasis on the domain scores rather than an overall ‘general’ or ‘global’ rating. Thus, individuals may report varying levels of ratings in different life domains, yielding more differentiated responses. Some research suggests the importance of such contextualized profiles given that overall ratings of life satisfaction may mask important domain-based differences. For example, Antaramian, Huebner, and Valois (2008) found that adolescents’ ratings of their family (but not general) satisfac- tion were related to their current family structure (i.e., intact vs. non-intact families). An example of this type of scale for adults is the Extended Satisfaction with Life Scale (Alfonso, Allison, Rader, & Gorman 1996 ), and an exam- ple of a scale for children is the Multidimensional Students’ Life Satisfaction Scale (Huebner, 1994 ). Empirical investigations have yet to resolve the ‘bottom up’ vs. ‘top down’ controversy. In fact, some research- ers have concluded that the effects are bidirectional ( Schimmack, 2008 ). Whatever the case, given the conceptual distinctions among the various measures, it appears that the decision as to which measure to select is best deter- mined by the particular purpose of the researcher or practitioner. It remains for the user to carefully consider the strengths and limitations of each approach and the associated measures. Although multi-method assessments are recommended ( Diener, Inglehard, & Tay 2013 ), self-report has been the main method of life satisfaction assessment. Other efforts have been undertaken (e.g., reports of others, obser- vations of smiling behavior, heart rate reactivity, memory for positive and negative events), but have been rela- tively understudied. Given the subjective nature of life satisfaction, self-reports are likely to remain the favored approach to assessment. A number of cautions have been raised regarding the validity of self-reports of life satis- faction. These cautions include response styles (e.g., social desirability, number use) and situational influences (e.g., priming, mood, item order, and cultural effects), which can increase errors of measurement. Nevertheless, Diener et al. (2013) have recently summarized the existing literature and concluded that such artifacts can usually be controlled. They further concluded that the overall literature supports the construct valid- ity of self-report life satisfaction scales, showing that they reveal important information about individuals’ per- ceptions of their lives. Nevertheless, some measures have stronger empirical support than others for some purposes. Thus, specific strengths and weaknesses of several widely used measures are discussed below. The purpose of this chapter is to present information on a number of instruments used to measure life satisfac- tion across the lifespan. It is hoped that this information will be of use to researchers interested in measuring life satisfaction variables as well as practitioners (e.g., psychologists, social workers, medical personnel) who wish to assess the perceived quality of life of individuals and/or groups. We used six criteria to guide our selection of measures. First, we tried to include one-dimensional and multidi- mensional self-report measures across all major age groups (youth, adults, seniors/third age) where possible. However, we excluded measures of life satisfaction that focused on single specific domains (e.g., health-related quality of life, job satisfaction, quality of school life). Second , we selected measures that primarily reflect cognitive judgments, omitting any that confounded affective (e.g., positive emotions) and cognitive judgments (e.g., Oxford Happiness Questionnaire; Hills & Argyle, 2002 ).Third , the final version of the instrument had to be developed within the past two decades or used in numerous research studies during the past two decades, yielding approxi- mately 30 citations or more (Web of Knowledge). Fourth , there had to be some information available related to normative samples, reliability, and validity. Fifth, the instrument had to be readily available to researchers, that is, available at no cost to the user. Sixth , we included only measures published after the prior addition of this book (i.e., 1991) with one exception. We included the Satisfaction with Life Scale ( Diener et al., 1985 ), which is the most widely cited measure of global life satisfaction for adults. In meeting the above criteria, we omitted a few noteworthy published instruments, but provide readers with the references (e.g., Frisch, 1994 ;Schalock, Keith, Hoffman, & Karan 1989 ).102 5. MEASURES OF LIFE SATISFACTION ACROSS THE LIFESPAN II. EMOTIONAL DISPOSITIONS
For organizational purposes, the measures were divided into two groups. The first group includes measures constructed for adults while the second group includes measures constructed for children (primarily for ages 8/C018 years). MEASURES REVIEWED HERE Measures of Life Satisfaction for Adults 1.Satisfaction with Life Scale ( Diener et al., 1985 ) 2.Temporal Satisfaction with Life Scale ( Pavot, Diener, & Suh. 1998 ) 3.Quality of Life Index ( Ferrans & Powers, 1985, 1992 ) 4.Personal Wellbeing Index ( Cummins, Eckersley, Pallant, Van Vugt, & Misajon 2003; International Wellbeing Group, 2013 ) 5.Extended Satisfaction with Life Scale ( Alfonso et al., 1996 ) 6.Quality of Life Enjoyment and Satisfaction Questionnaire ( Endicott, Nee, Harrison, & Blumenthal 1993; Ritsner, Kurs, Gibel, Ratner & Endicott 2005 ) 7.Life Satisfaction Index for the Third Age ( Barrett & Murk, 2006 ) Measures of Life Satisfaction for Youth 1.Students’ Life Satisfaction Scale ( Huebner, 1991b ) 2.Perceived Life Satisfaction Scale ( Adelman et al., 1989 ) 3.Multidimensional Students’ Life Satisfaction Scale ( Huebner, 1994 ) OVER VIEW OF THE MEASURES The measures selected here for review represent different models (i.e., bottom up vs. top down, unidimen- sional vs. multidimensional) of assessment of life satisfaction and perceived quality of life. The first seven mea- sures were predominantly developed for adults and seniors, whereas the last three are assessment tools of life satisfaction of young people (aged 8 years and above). We start with the Satisfaction with Life Scale (Diener et al., 1985 ) as a measure of global life satisfaction. This brief scale consists of five items yielding a total score representing satisfaction with life as a whole. Next, the Temporal Satisfaction with Life Scale (Pavot et al., 1998 ), which also follows the top down strategy, added a new perspective to the assessment of global life satisfaction by measuring three temporal dimensions of life satisfac- tion (i.e., past, present, and future life satisfaction). This measure consists of 15 items yielding a total life satisfac- tion score, and three subscale scores (one for each temporal dimension). The Quality of Life Index (Ferrans & Powers, 1985, 1992 ) assesses quality of life focusing on an individual’s judgments of satisfaction with and impor- tance of different life domains (e.g., physical health and functioning). The measure consists of 32 items that are rated with respect to the extent of satisfaction and importance. Subscale scores (multidimensional model) as well as a total scale score (bottom up strategy) can be obtained. The Personal Wellbeing Index (e.g., International Wellbeing Group, 2013 ) assesses adults’ quality of life utilizing one item that asks for satisfaction with life as a whole, and additional eight domain-specific items (e.g., for satisfaction with standard of living). The domain- specific items can be used individually (multidimensional model), or can be summarized to a total score (bottom up) of quality of life. With the Extended Satisfaction with Life Scale (Alfonso et al., 1996 ), we review a measure focusing on an individual’s satisfaction in life with respect to eight life domains (e.g., social life). The 50 items yield one total life satisfaction score, and eight domain-specific subscale scores. As another example following a multidimensional model, the Quality of Life Enjoyment and Satisfaction Questionnaire (e.g., Endicott et al., 1993 ) assesses health-related quality of life. Sixty items form the basic measure, which includes five subscales (e.g., physical health). Furthermore, a General QOL Index can be obtained. As the last measure in the group of assess- ments in adulthood, we review the Life Satisfaction Index for the Third Age (Barrett & Murk, 2006 ) assessing life sat- isfaction of people in their ‘third age’ (i.e., seniors). This measure comprises 35 items assessing five different subscales (e.g., zest vs. apathy). A total life satisfaction score can also be computed. This measure is a multidi- mensional one that utilizes the bottom up strategy to assess satisfaction with life.103 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
The next section focuses on a group of measures of life satisfaction in children and adolescents. We start with theStudents’ Life Satisfaction Scale (Huebner, 1991b ). This brief assessment tool consists of seven items that lead to a total score of young peoples’ satisfaction with life as a whole. Next, the Perceived Life Satisfaction Scale (Adelman et al., 1989 ) focuses on young peoples’ satisfaction in different life domains (e.g., material and physical well-being). Nineteen items yield a total score of perceived satisfaction with life. Finally, the Multidimensional Students’ Life Satisfaction Scale (Huebner, 1994 ) is a multidimensional assessment of satisfaction with specific domains (e.g., satisfaction with friendships). Its 40 items yield a total life satisfaction score, and five domain- specific subscale scores. More detailed descriptions of the life satisfaction measures reviewed in this chapter follow below. For each measure, we present information on (1) theoretical conceptualization and key references; (2) description of the items and response options; (3) sample(s); (4) reliability; (5) validity; (6) location; (7) psychometric strengths and weaknesses; and (8) a sample of the actual measure. Satisfaction with Life Scale (SWLS) (Diener et al., 1985 ) Variable Diener et al. (1985) defined global life satisfaction as a cognitive judgment of the quality of one’s own life. Cognitive ‘judgments of satisfaction are dependent upon a comparison of one’s circumstances with what is thought to be an appropriate standard. It is important to point out that the judgment of how satisfied people are with their present state of affairs is based on a comparison with a standard which each individual sets for him or herself; it is not externally imposed’ ( Diener et al., 1985 , p. 71). Description The SWLS consists of five items assessing individuals’ global life satisfaction. Respondents rate their agree- ment with each item on a 7-point Likert-type response scale (1 5strongly disagree to 75strongly agree ). A total score can be obtained by summing the responses to all five items. Scores can be interpreted in terms of relative life satisfaction by comparing individual scores with scores from normative samples, but also absolutely (i.e., 5 /C095extremely dissatisfied; 10 /C0145dissatisfied; 15 /C0195slightly dissatisfied; 20 5neutral; 21 /C0255 slightly satisfied; 26 /C0305satisfied; 31 /C0355extremely satisfied [ Pavot & Diener, 1993 ]). Sample Three samples were studied to develop the SWLS ( Diener et al., 1985 ). Sample 1 ( N5176 undergraduates; no further information on age) was used to examine the psychometrics (e.g., M, SD, internal consistency, test /C0retest reliability) and the validity of the measure. Sample 2 ( N5163 undergraduates; no further information on age) was used to examine convergent and discriminant validity. With sample 3 ( N553; individuals with a mean age of 75 years), the properties of the measure in elderly persons were examined. Further normative data for different groups (e.g., students, adults, health-related samples) were reported in Pavot and Diener (1993, 2008) .Diener et al. (1985) reported a mean life satisfaction score of 23.5 ( SD56.43) for sample 1. Reliability Internal Consistency The 5-item SLWS shows a high Cronbach alpha coefficient of α5.87 (Diener et al., 1985 ). Likewise, Pavot and Diener (1993) reported alpha coefficients ranging between α5.79 and α5.89. Test/C0Retest Two-month test /C0retest reliability of the SWLS is rtt5.82 (Diener et al., 1985 ). Further research on the test /C0ret- est stability yielded coefficients of rtt5.83 (2 weeks), rtt5.84 (1 month), rtt5.64 and .82 (2 months), rtt5.50 (10 weeks), and rtt5.54 (4 years) (cf. Pavot & Diener, 1993 ).104 5. MEASURES OF LIFE SATISFACTION ACROSS THE LIFESPAN II. EMOTIONAL DISPOSITIONS
Validity Convergent/Concurrent The SWLS exhibited positive correlations with several measures of subjective well-being ( Diener et al., 1985 ). For example, the SWLS correlated with the Fordyce (1978) single item measure of happiness ( r5.57 to r5.58), the Fordyce percent of time happy question ( r5.58 to r5.62), Bradburn’s (1969) measures of positive affect (r5.50 to r5.51), and Andrews and Withey’s (1976) Delighted /C0Terrible scale ( r5.62 to r5.68) (sample 1 and 2). In the elderly sample, the SWLS correlated with the Life Satisfaction Index ( Adams, 1969 ) with a moder- ate coefficient of .46 (sample 3; Diener et al., 1985 ). Divergent/Discriminant The SWLS exhibited negative correlations with Bradburn’s (1969) measure of negative affect ( r52.32 to r52.37). The SWLS also exhibited a non-significant relationship ( r5.02) with the Marlowe /C0Crown scale (Crowne & Marlowe, 1964 ), suggesting that SWLS scores are unrelated to a socially desirability response style (sample 2; Diener et al., 1985 ). Construct/Factor Analytic Factorial validity was estimated via a principal axis factor analysis of the item intercorrelations in sample 1 (N5176). A Cattell scree plot of eigenvalues ( Cattell, 1978 ) suggested that the five items of the SWLS formed a single factor ( Diener et al., 1985 ). Criterion/Predictive Evidence of predictive validity is presented in Pavot, Diener, Colvin, and Sandvik (1991) . Location Diener, E., Emmons, R. A., Larsen, R. J., & Griffin, S. (1985). The Satisfaction with Life Scale. Journal of Personality Assessment ,49,7 1/C075. Results and Comments Substantial research evidence supports the reliability and validity of the SWLS as a measure of adults’ global life satisfaction. This widely used and brief assessment tool can be integrated in large-scale assessments, but also in all other kinds of studies where a measure of domain-free life satisfaction is of interest. The SWLS has been adapted into several languages (e.g., Arabic, Chinese, Hebrew, Russian, Setswana). Furthermore, the SWLS inspired the development of further multi-item measures of life satisfaction, some of which are presented in this chapter. The SWLS appears to be a useful measure of global life satisfaction within a broad age range (e.g., undergradu- ates, middle-aged adults, and elderly individuals). Recently, a version for children has been developed (SWLS-C; Gadermann, Schonert-Reichl, & Zumbo 2010 ) based on the SWLS. The five items and the response format have been adapted for children in grades 4 to 7. Research on the SWLS-C suggests that it is a promising measure of children’s global life satisfaction, but additional research would be beneficial ( Gadermann et al., 2010 ). SATISFACTION WITH LIFE SCALE Below are five statements that you may agree or dis- agree with.

Temporal Satisfaction with Life Scale (TSWLS) (Pavot et al., 1998 ) Variable The TSWLS measures three temporal dimensions of life satisfaction /C0past, present, and future life satisfaction. The TSWLS is based on the Satisfaction with Life Scale (SWLS; Diener et al., 1985 ).Pavot et al. (1998) rephrased the five original SWLS items with respect to all three time frames of interest. Description The TSWLS consists of 15 items assessing individuals’ global life satisfaction, separated on the basis of three temporal dimensions (i.e., the past, present, and future satisfaction). Respondents rate their agreement with each item on a 7-point Likert-type response scale (1 5strongly disagree to 75strongly agree ). All 15 items are positively keyed. Four scores can be obtained for analyses. First, summing all 15 items leads to a total score ranging between 15 and 105. Second, summing the five items for each temporal dimension (past satisfaction, present sat- isfaction, and future satisfaction, respectively) provides three subscale scores ranging from 5 to 35. Sample Pavot et al. (1998) presented three samples. Sample 1 consisted of 157 students (mainly aged from 18 to 25 years) who filled in the TSWLS on three occasions with a 4-week interval between administrations 1 and 2, and a 5-week interval between administrations 2 and 3. Total score means were 63.61 ( SD516.03), 69.39 ( SD516.20), and 69.96 ( SD516.42) for administration 1, 2, and 3, respectively. Means for the three subscales past, present, and future satisfaction were 20.98 ( SD56.58), 21.79 ( SD55.96), and 26.32 ( SD54.81), respectively. The differ- ences between means of past vs. future, and present vs. future were statistically significant. There were no signifi- cant differences between means of past vs. present satisfaction subscales. Sample 2 consisted of 294 adults ( M559 years; ranging from 25 to 88 years) and yielded a mean for the total score of 70.80 ( SD514.83). Means for the three subscales were 22.52 ( SD56.81), 24.49 ( SD56.37), and 23.79 (SD55.93) for past, present, and future satisfaction, respectively. The differences between means of past vs. pres- ent, and past vs. future were statistically significant. There were no significant differences between means of pres- ent vs. future satisfaction subscales. Sample 3 consisted of 66 older adults ( M579 years; ranging from 61 to 99 years) who filled in the TSWLS on two occasions over a 4 /C06 week interval with total score means of 72.89 ( SD519.30), and 74.28 ( SD515.90). Means for the three subscales were 23.34 ( SD57.24), 25.93 ( SD55.54), and 24.83 ( SD55.94) for past, present, and future satisfaction, respectively. The differences between means of past vs. present, and present vs. future were statistically significant. No significant differences were observed between means of past vs. future satisfac- tion subscales. Reliability Internal Consistency The total 15-item TSLWS exhibited Cronbach alpha coefficients ranging from α5.91 to α5.93 in all three samples. Test/C0Retest In the sample of students (sample 1), test /C0retest reliability coefficients were rtt5.83 (4 weeks), rtt5.88 (5 weeks), and rtt5.82 (9 weeks), respectively. No test /C0retest correlation coefficients were reported for sample 2 and 3. Validity Convergent/Concurrent According to Pavot et al. (1998) , the total TSWLS correlated .89 and .74 with the original 5-item SWLS in sam- ple 1 and 2, respectively. In sample 1, the total TSWLS correlated substantially with other measures of subjective well-being, for example, with the Andrews and Withey (1976) Delighted /C0Terrible scale ( r5.75). In sample 1, self-rated optimism ( Scheier & Carver, 1985 ) correlated positively with past ( r5.48), present ( r5.53), and future satisfaction ( r5.64). In sample 2, satisfaction was positively correlated with SWLS exhibiting coefficients of106 5. MEASURES OF LIFE SATISFACTION ACROSS THE LIFESPAN II. EMOTIONAL DISPOSITIONS
r5.72 (past satisfaction), r5.92 (present satisfaction), and r5.59 (future satisfaction). In sample 3, self-rated optimism ( Scheier & Carver, 1985 ) exhibited positive correlations of r5.45,r5.22, and r5.38 with past, present, and future satisfaction, respectively. In sample 3, correlations between extraversion ( Costa & McCrae, 1992 ) and satisfaction were r5.34 (past satisfaction), r5.19 (present satisfaction), and r5.40 (future satisfaction). Divergent/Discriminant In sample 1, the TSWLS yielded significant but lower coefficients with measures of the affective components of subjective well-being (SWB) than with measures of the cognitive component (e.g., SWLS; Diener et al., 1985 ). In sample 3, correlations between the TSWLS and peer-rated optimism ( Scheier & Carver, 1985 ) and self-rated openness ( Costa & McCrae, 1992 ) were not significant. Negative correlations were obtained between neuroticism (Costa & McCrae, 1992 ) and satisfaction, with r52.58 (past satisfaction), r52.46 (present satisfaction), and r52.52 (future satisfaction) in sample 3. Construct/Factor Analytic An orthogonally rotated principal components analysis of the data from sample 2 yielded a three-dimensional solution. Three components that represented the items of past satisfaction, present satisfaction, and future satis- faction, respectively, with eigenvalues greater than 1 explained 73.80% of the total variance. Criterion/Predictive Correlations between self-reported health and the TSWLS yielded coefficients of r5.41, r5.32, r5.39, and r5.45 for past, present, and future satisfaction as well as the total score of the TSWLS, respectively (sample 3). A hierarchical regression analysis with a composite score for SWB (i.e., peer-reported SWLS and peer-reported happiness scores [ Fordyce, 1977 ]) as the criterion variable, and the three time dimensions of the TSWLS as pre- dictors, yielded significant R2-changes for the future satisfaction score in step 3, over and above the significant increment of present satisfaction in step 1. Past satisfaction, entered in step 2, failed to explain significant addi- tional variance. Nevertheless, the results show the incremental validity due to adding in the temporal aspect when assessing life satisfaction among adults. Location Pavot, W., Diener, E., & Suh., E. (1998). The Temporal Satisfaction with Life Scale. Journal of Personality Assessment ,70, 340/C0354. Results and Comments Research on the TSWLS has provided promising, preliminary evidence of its reliability and validity as a mea- sure of global life satisfaction suitable for young, middle, and older-aged individuals (from 18 to 99 years). Divergence across a number of validation variables (e.g., optimism, extraversion) among the three time frames was reported, which supports the meaningfulness of the TSWLS scores. The TSWLS is based on the idea that it can be useful when judging life as a whole to have the opportunity to differentiate past, present, and future- related perspectives. The inclusion of the temporal dimensions opens the possibility of research investigating the roles and antecedents of life satisfaction from a developmental perspective.

Quality of Life Index (QLI) (Ferrans & Powers, 1985, 1992 ) Variable Ferrans and Powers (1992) defined quality of life ‘as a person’s sense of well-being that stems from satisfaction or dissatisfaction with the areas of life that are important’ for the person (p. 29). In choosing the label ‘satisfac- tion’ they highlighted the idea that quality of life is determined by a judgment and evaluation of life conditions. Following Campbell (1981) ,Ferrans and Powers (1985) considered satisfaction of needs in different life domains as being relevant for an individual’s quality of life with the perceived discrepancy and achievement of needs ranging from fulfillment to deprivation. Need in this approach was defined as ‘the amount of a particular reward that a person may require’ ( Ferrans & Powers, 1985 , p. 17). Description The QLI measures quality of life considering an individual’s satisfaction with and importance of different life domains (e.g., health care, physical health and functioning, marriage, family, friends, stress, standard of living, occupation). Item content was derived from a literature review on quality of life and reports of patients about the effects of hemodialysis on their quality of life. The QLI consists of 32 items that are rated twice, once for the extent of satisfaction (1 5very dissatisfied to 65very satisfied ) and once for their importance (1 5very unimportant to 65very important ). For use with dialysis patients, three more items measure aspects related to dialysis treat- ment. According to Ferrans and Powers (1985) , a total score and four subscales can be computed, namely health and functioning (12 items), socioeconomic (9 items), psychological/spiritual (7 items), and family (4 items). Sample The first sample ( Ferrans & Powers, 1985 ) consisted of 88 graduate students (97% females) with a mean age of 33.1 years (ranging from 23 to 52 years). The students completed the QLI in a paper-pencil questionnaire format. The second sample (clinical sample; Ferrans & Powers, 1985 ) consisted of 37 dialysis patients (72% males) with a mean age of 50.0 years (ranging from 24 to 75 years). The patients answered the QLI items in an interview for- mat. The third sample (dialysis patients; Ferrans & Powers, 1992 ) consisted of 349 in-unit hemodialysis patients (56% males) with a mean age of 55.2 years (ranging from 25 to 84 years). This sample was representative of the population of adult in-unit hemodialysis patients in terms of gender ratio, months in dialysis, presence of diabe- tes mellitus, or primary cause of renal failure, but it was slightly older, and had a higher ratio of white patients. This sample responded to the QLI items in a paper-pencil questionnaire format. The first and the second sample were used for initial examination of reliability and validity of the QLI total scale. The third sample was utilized to study the factor structure of the QLI, and to further examine validity and reliability of the total scale and the subscales. Reliability Internal Consistency Cronbach alpha coefficients for the total scale ranged from α5.90 to α5.93 for the three samples. Alpha coef- ficients for the subscales were α5.87 (health and functioning), α5.82 (socioeconomic), α5.90 (psychological/ spiritual), and α5.77 (family). Test/C0Retest Test/C0retest correlations were rtt5.87 for students ( n569; two-weeks interval) and rtt5.81 for patients ( n520; one-month interval) ( Ferrans & Powers, 1985 ).108 5. MEASURES OF LIFE SATISFACTION ACROSS THE LIFESPAN II. EMOTIONAL DISPOSITIONS
Validity Convergent/Concurrent The correlations of the QLI and a one-item rating of the overall satisfaction with life (How satisfied are you with your life? 1 5very dissatisfied to 65very satisfied ) were r5.75 for the students, r5.65 for the patients of the second sample, and r5.77 for the patients in the third sample ( Ferrans & Powers, 1992 ).Ferrans and Powers (1992) showed that the means for the socioeconomic subscale differed between lower (less than $10,000 annual family income; M519.58) and higher income participants ($10,000 and more annual family income; M521.70). As expected, all other subscales and the total scale did not show any differences between the lower and higher income participants. Divergent/Discriminant Atkinson, Zibin, and Chuang (1997) reported that the overall score of the QLI was not related to educational level, employment status, years of unemployment, housing arrangement, and social involvement in patients with schizophrenia ( N569;rs ranging from .01 to .16). Construct/Factor Analytic Ferrans and Powers (1992) reported results from a factor analysis with oblique promax rotation utilizing the satisfaction responses weighted by importance. Examinations of the Scree plot, relative chi-square, simple struc- ture, and presence of trivial factors suggested extraction of four factors explaining 91% of the variance. The inter- correlations among the factors ranged from .31 to .60. A higher-order factor analysis yielded a single broad QLI factor. The first-order factors health and functioning, socioeconomic, psychological/spiritual, and family exhib- ited loadings of .70, .69, .85, and .48, respectively, on the higher-order QLI factor ( Ferrans & Powers, 1992 ). Criterion/Predictive According to Haywood, Garratt, Schmidt, Mackintosh, and Fitzpatrick (2004, p. 72) , following recovery from a period of intensive care, ‘greater perceived health (and future health), greater social support, and hospital read- mission explained 51% of the variance in higher QLI scores.’ Location Ferrans, C. E., & Powers, M. J. (1985). Quality of Life Index: Development and psychometric properties. Advances in Nursing Science ,8,1 5/C024. Ferrans, C. E., & Powers, M. J. (1992). Psychometric assessment of the Quality of Life Index. Research in Nursing and Health, 15, 29/C038. Results and Comments The QLI is one of the few measures of life satisfaction for adults that contain multiple items for each domain. It provides a total score for quality of life and scores for the four subscales: health and functioning, socioeco- nomic, psychological/spiritual, and family. Results of research with the QLI to date suggest satisfactory reliabil- ity and validity, although further evidence for predictive validity and construct validity, especially discriminant validity, is needed. The measure appears to demonstrate usefulness in clinical settings, and it also appears suitable for healthy people. Different versions have been developed for very different groups of patients (e.g., cardiac, respiratory, cancer, and burn patients). Each of these versions includes the same set of 32 core items that are judged with respect to the individual’s satisfaction and importance. Additionally, items are added to those core items to address group-specific issues. Results presented by Ferrans and Powers (1992) showed that the socioeconomic subscale differentiates between lower and higher income participants. Future research is needed to further investigate the discrimina- tion of different groups like healthy vs. unhealthy participants, who would be expected to show different means on the subscale of health and functioning. Additionally, Ferrans and Powers (1992) provided several ideas regarding how to improve the QLI (e.g., items relating to leisure activities or social support could be split up into different components to reduce conceptual ambiguity). Finally, the replicability of the factor structure should be addressed in future studies as well, because Ferrans and Powers (1992) highlighted some sample-specific aspects of the reported factorial structure of the QLI in in-unit hemodialysis patients.109 OVERVIEW OF THE MEASURES II.

MEASURES OF LIFE SATISFACTION ACROSS THE LIFESPAN II. EMOTIONAL DISPOSITIONS
Personal Wellbeing Index (PWI) (Cummins et al., 2003; International Wellbeing Group, 2013 ). Variable There are hundreds of well-being measures available, but many of them are designed for highly specific sub- groups of individuals (e.g., cancer patients, individuals with disabilities), and therefore, are not useful in examin- ing the general population. To the contrary, measures for the general population often cannot be used within specific groups (cf. International Wellbeing Group, 2013 ). Furthermore, most of those measures do not clearly discriminate between objective and subjective aspects of quality of life ( International Wellbeing Group, 2013 ). The Personal Wellbeing Index (PWI) was thus constructed for the assessment of the subjective dimension of qual- ity of life in both the general population and specific subgroups. The PWI is based on the Comprehensive Quality of Life Scale ( Cummins, 1997 ), and is part of the Australian Unity Wellbeing Index ( Cummins et al., 2003) comprising both the PWI and the National Wellbeing Index (NWI). The PWI assesses adults’ satisfaction with life as a whole, and satisfaction with life in different life domains. Description The PWI consists of eight items assessing individuals’ life satisfaction. One item assesses satisfaction with life as a whole, whereas seven additional items assess domain-specific satisfaction (i.e., satisfaction with standard of living, health, achievements, personal relationships, personal safety, community connectedness, and future secu- rity). In a revised version ( International Wellbeing Group, 2013 ), the domain of religiousness has been added. Respondents rate their agreement with each item on an 11-point Likert-type response scale (0 5completely dissatis- fiedto 105completely satisfied ). Scoring of the PWI involves analyzing each of the 7 (excluding religiousness) or 8 (including religiousness) domain items as a separate variable, or computing a total score that can be obtained by averaging all 7 or 8 domain-specific items ( International Wellbeing Group, 2013 ). The scores are then converted using the formula ‘(score/10) 3100’ to produce percentage of scale maximum units on a 0 to 100 distribution (cf. Cummins et al., 2003 ). Sample Cummins et al. (2003) reported findings from a nationally representative sample of 2,000 Australians (ranging in age from 18 to 76 1years). This sample yielded a mean score of 75.48 ( SD519.67) for the single item on satis- faction with life as a whole. Means were reported for satisfaction with standard of living ( M575.78, SD519.50), health ( M573.97, SD521.38), achievements ( M573.48, SD518.51), personal relationships ( M578.44, SD521.22), personal safety ( M575.40, SD520.25), community connectedness ( M568.98, SD520.84), and future security ( M569.29, SD521.24). For the composite score of the PWI consisting of all seven domains, a mean of 73.48 ( SD513.57) was found ( Cummins et al., 2003 ). Reliability Internal Consistency The PWI exhibited Cronbach alpha coefficients ranging between α5.70 and α5.85 across several studies (International Wellbeing Group, 2013 ). Test/C0Retest Across a 1 /C02 week interval, the PWI yielded an intraclass correlation of .84 ( Lau & Cummins, 2005 ). Validity Convergent/Concurrent Cummins et al. (2003) reported that the PWI total score correlated substantially with satisfaction with life as a whole ( r5.67). Participants within the two highest impact groups of a happy event scored higher on the PWI as compared with lower impact groups ( Cummins et al., 2003 ). The International Wellbeing Group (2013) reported a correlation of .78 between the PWI and the SWLS ( Diener et al., 1985 ).Renn et al. (2009) reported positive correlations between PWI, and both the environmental mastery subscale ( r5.59), and the self-acceptance subscale ( r5.68) of the Scales of Psychological Well-Being (SPWB; Ryff & Keyes, 1995 ) in an Austrian sample ( N5573 college students).111 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
Divergent/Discriminant Renn et al. (2009) reported that the PWI was weakly correlated with the SPWB scales of autonomy (r5.28), personal growth (r5.22), and purpose in life (r5.17) in an Austrian sample ( N5573 college students) . Construct/Factor Analytic Cummins et al. (2003) reported results of a principal components analysis (with oblimin rotation) based on the intercorrelations of the seven domain-based items of the PWI, as well as three additional items from the National Wellbeing Index (NWI; i.e., economic situation, state of the environment, social conditions). This analysis yielded two components with one representing all seven PWI items and another representing the three items of the NWI. The loadings of the PWI items ranged from .51 to .72. The two indices (i.e., PWI and NWI) correlated positively (r5.44). The items of the 8-domain version also consistently form a single factor accounting for about 50% of the variance ( International Wellbeing Group, 2013 ). Criterion/Predictive According to Cummins et al. (2003) , on the domain level, satisfaction with standard of living emerged as the most substantial predictor ( β5.32) of overall satisfaction, followed by satisfaction with achievement and relation- ships with β5.20 and β5.19, respectively. Satisfaction with health, future security, and community also emerged as significant predictors of overall satisfaction with β5.14,β5.10, and β5.08, respectively. Satisfaction with safety did not contribute to explaining variance in satisfaction with life as a whole, but it contributed to predict- ing other variables (e.g., social capital, National Wellbeing Index, life in Australia).

Source: www.deakin.edu.au/research/acqol/iwbg/wellbeing- index/index.php (Retrieved May 9, 2014). Results and Comments Research into the psychometric properties of the PWI has been somewhat sparse, but the findings to date are promising. The PWI seems to be useful for a broad age-range from younger adults to elderly people (18 to 761years). For young people, a pre-school version (PWI-PS; Cummins & Lau, 2005a ), and a school-children and adolescents’ version (PWI-SC; Cummins & Lau, 2005b ) have been developed. Furthermore, a version has been developed for individuals with intellectual disabilities, the PWI-ID ( Cummins & Lau, 2005c ). As the PWI is a brief measure of subjective quality of life, it is useful for several research purposes, but it also may be useful for applied professionals in different areas (e.g., counseling, program evaluation). Like the interna- tionally used SWLS ( Diener et al., 1985 ), the PWI has been used in several languages as a brief scale assessing sat- isfaction with life as a whole and domain-specific satisfaction in adults. PERSONAL WELLBEING INDEX The following questions ask how satisfied you feel, on a scale from zero to 10. Zero means you feel no satis- faction at all and 10 means you feel completely satisfied.

EMOTIONAL DISPOSITIONS
Extended Satisfaction with Life Scale (ESWLS) (Alfonso et al., 1996 ) Variable Alfonso et al. (1996) defined the cognitive component of subjective well-being as the ‘intellectual evaluation of one’s life satisfaction either globally or with respect to specific life domains’ (p. 276; cf. Andrews & Robinson, 1991;George, 1981 ;Myers & Diener, 1995 ;Pavot & Diener, 1993 ). The selected domains of interest were those highlighted within well-known, sophisticated approaches to subjective well-being and life satisfaction as well as those being most strongly related to overall subjective well-being and those applicable to most people (e.g., Alfonso, 1995 ;Alfonso, Allison, & Dunn 1992 ;Diener, 1984 ;Myers & Diener, 1995 ). These domains are social life, sexual life, relationship, self, physical appearance, family life, school life, and job. Description The ESWLS measures an individual’s satisfaction with life in general, and with respect to eight life domains (i.e., social life, sexual life, relationships, self, physical appearance, family life, school life, and job) with a total of 50 items, using a 7-point Likert-type response format (ranging from 1 5strongly disagree to 75strongly agree ). All subscales are measured with five items except for job satisfaction, which comprises 10 items. Items of the ESWLS (except school life and job) were based on the phrasing of the SWLS items ( Diener et al., 1985). The SWLS items were replicated with minor modifications. For example, Alfonso et al. (1996) changed ‘In most ways my life is close to my ideal’ to ‘In most ways my social life is close to my ideal’. The SWLS item ‘If I could live my life over, I would change almost nothing’ was modified to ‘I am generally pleased with my life I lead’ to exclude the regret-related connotation of this item (cf. Alfonso et al., 1996 ). The items measuring school life derived from the Perceived Quality of Academic Life scale (PQAL; Okun, Kardash, Stock, Sandler, & Baumann 1986), but were converted to the wording of the rest of the items of the ESWLS. Job satisfaction items were based on the Minnesota Satisfaction Questionnaire /C0Short Form (MSQ; Weiss, Dawis, England, & Lofquist 1967 ), but are not identical with respect to wording. Sample The total sample was comprised of 302 undergraduate students, which were mainly white, single, and had middle class backgrounds. The exact number of respondents varied across subscales from 182 for job satisfaction to 302 for satisfaction with self. A total of 109 participants completed the ESWLS twice allowing for analyzing the test/C0retest reliability. Means of the five-item scales ranged from 19.6 (physical appearance) to 25.1 (social life, self) with standard deviations ranging from 4.7 (school life) to 8.3 (family life). The 10-item subscale of job satis- faction had a mean of 48.2 with a standard deviation of 11.0 (cf. Alfonso et al., 1996 ). Reliability Internal Consistency For the five-item scales, Cronbach alpha coefficients were high ranging from α5.81 (school life) to α5.96 (social life, sex life, relationship). Job satisfaction exhibited a high alpha coefficient as well ( α5.88) ( Alfonso et al., 1996 ). Test/C0Retest Two-week test /C0retest reliability coefficients ranged from rtt5.74 (school life) to rtt5.87 (sex life) ( Alfonso et al., 1996 ). Validity Convergent/Concurrent Intercorrelations among the subscales of the ESWLS, and correlations between the ESWLS and the Rosenberg Self Esteem Scale (RSE; Rosenberg, 1965 ), and Self-Deception Subscale of the Balanced Inventory of Desirable Responding (BIDR; Paulhus, 1991 ) were reported as indicators of convergent validity in Alfonso et al. (1996) . The domain-related subscales of the ESWLS showed positive correlations with the general satisfaction score with coefficients ranging from r5.28 (school) to r5.63 (self). The intercorrelations among the domain specific sub- scales ranged from r5.11 (relationship /C0physical appearance) to r5.57 (relationship /C0sex life). The subscale of113 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
self exhibited the strongest correlations with the RSE and the Self-Deception Subscale of the BIDR, with coeffi- cients of r5.59 and r5.49, respectively. The other subscales showed correlation coefficients between r5.12 (job) and r5.48 (general life) with the RSE, and between r5.11 (job) and r5.35 (social life) with the Self-Deception Subscale of the BIDR. Divergent/Discriminant The Impression Management (IM) subscale of the BIDR and the Agreement Response Scale (ARS; Couch & Keniston, 1960 ) were utilized as measures for social desirability and acquiescence, respectively. The ESWLS sub- scales were only modestly related to IM with correlation coefficients ranging between r5.09 (physical appear- ance) and r5.31 (school). The ARS was not related to the ESWLS subscales (coefficients ranged between r52.16 and r5.14). Construct/Factor Analytic In a principal components analysis (with direct oblimin rotation) of the intercorrelations of 40 items of the ESWLS (i.e., without the job subscale), Alfonso et al. (1996) extracted eight components that explained 77% of the variance. In a confirmatory factor analysis (CFA), indices indicated a modest fit, with NFI 5.79, AGFI 5.69, and RMSR 5.06. Correlations among the components ranged from r5.00 (physical appearance /C0school) to r5.46 (general life /C0social life), with a median of r5.26. Correlations among the CFA latent traits ranged from r5.07 (physical appearance /C0school life) to r5.75 (general life /C0self) with a median of r5.34.

B., Rader, D. E., & Gorman, B. S. (1996). The Extended Satisfaction with Life Scale: Development and psychometric properties. Social Indicators Research ,38,2 7 5/C0301. Results and Comments The ESWLS is one of the few multidimensional measures of life satisfaction for adults that contain multiple items for each domain. While the research base for the ESWLS is relatively sparse, the findings are promising. The preliminary results for the ESWLS suggested satisfactory internal consistency and test /C0retest reliability as well as evidence of validity in a sample of college students. The ESWLS is a measure that can potentially be used in various age groups, ranging from adolescents to elderly. The authors of the ESWLS indicated that an individ- ual should have a reading level of at least the seventh grade to be able to understand the ESWLS. However, stud- ies of the psychometric properties of the measure with different populations (e.g., older adults, psychiatric patients) are needed to assess its range of applicability.

Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) and Abbreviated Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q-18) (Endicott et al., 1993; Ritsner et al., 2005 ) Variable These measures are designed to assess the degree of enjoyment and satisfaction experienced by individuals in different areas of daily functioning ( Endicott et al., 1993 ) in order to measure the health-related quality of life (QOL; Ritsner et al., 2005 ). The Q-LES-Q and its abbreviated form (Q-LES-Q-18), primarily measure individuals’ judgments of ‘how they feel about what they have, how they are functioning, and their ability to derive pleasure from their life activities’ ( Endicott et al., 1993 , p. 321). Description Q-LES-Q The Q-LES-Q consists of 93 rationally derived items and comprises a total of eight subscales and two individ- ual items (satisfaction with medication; overall satisfaction and contentment) with a 5-point Likert-type response format (ranging from 1 5not at all or never to 55frequently or all of the time ). A subset of 60 items forms the core of the Q-LES-Q (also labeled as basic Q-LES-Q) and is answered by all participants. This core comprises five115 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
subscales, namely physical health (13 items), subjective feelings (14 items), leisure time activities (6 items), social relationships (11 items), and general activities (14 items) as well as the two individual items. The three subscales of work (13 items), household duties (10 items), and school/course work (10 items) are given to participants for whom those activities are applicable. The General QOL Index is comprised of the average score of all items of the basic Q-LES-Q. The questionnaire takes between 40 and 45 minutes to administer. Q-LES-Q-18 The Q-LES-Q-18 consists of 18 items with a 5-point Likert-type response format (ranging from 1 5not at all or never to 55frequently or all of the time ) and measures four of the five subscales of the basic Q-LES-Q. These sub- scales are physical health (4 items), subjective feelings (5 items), leisure time activities (3 items), and social rela- tionships (5 items). The General QOL Index is comprised of the average score of all items of the Q-LES-Q-18. The completion of the questionnaire takes between 10 and 12 minutes. The items of the basic Q-LES-Q were selected for the Q-LES-Q-18 in a two-stage process. In the first stage, items were selected that best predicted each of the subscales of the basic Q-LES-Q. In the second stage, a factor analysis revealed that the subscale of general activity could not be extracted. Hence, it was excluded from the abbreviated form of the Q-LES-Q. Sample Endicott et al. (1993) reported results from 85 outpatients who met the DSM-III-R criteria for major depression. Their mean age was 39.1 years (ranging from 18 to 63 years) and 59% were female. All participants responded to the 93 items of the Q-LES-Q. Ritsner et al. (2005) reported results from 339 inpatients (70.8% male) who met the DSM-IV criteria for schizo- phrenia ( n5237), schizoaffective, and mood (major depression or bipolar) disorders (total nfor the last two groups 5102). Their mean age was 38.5 years. All participants responded to the 60 items of the basic Q-LES-Q. A subset of 199 patients (74.9% male; age: M538.9; n5148 with schizophrenia, n551 with schizoaffective/ mood disorder) completed the basic Q-LES-Q again 16 months after the first assessment. Furthermore, Ritsner et al. (2005) reported results based on the basic Q-LES-Q of 133 outpatients (76.7% males) with a mean age of 39.6 years. They all fulfilled the DSM-IV criteria for schizophrenia. Finally, 175 healthy participants (27.1% male; age: M538.4) completed the basic Q-LES-Q. Ritsner et al. (2005) also reported results for the Q-LES-Q-18 whose scales were extrapolated from the items of the Q-LES-Q. Reliability Internal Consistency Cronbach alpha coefficients of the Q-LES-Q subscales ranged from α5.90 (general activities) to α5.96 (work) among outpatients with major depression ( Endicott et al., 1993 ). Among inpatients, alpha coefficients for the basic Q-LES-Q measure ranged from α5.87 (social relationships) to α5.91 (subjective feelings), while the alpha coeffi- cient for the General QOL Index wasα5.96 (Ritsner et al., 2005 ). Ritsner et al. (2005) reported alpha coefficients of the subscales of the Q-LES-Q-18 ranging from α5.76 (social relationships) to α5.80 (leisure time activities), from α5.82 (subjective feelings) to α5.89 (leisure time activi- ties), and from α5.74 (leisure time activities) to α5.78 (social relationships), for the inpatients, outpatients, and healthy sample, respectively. The extrapolated general activity scale yielded high alpha coefficients as well (i.e., α5.78,α5.85, and α5.71 for the inpatients, outpatients, and healthy sample, respectively). The total score of the Q-LES-Q-18 yielded alpha coefficients of α5.93,α5.96, and α5.88 in the inpatients, outpatients, and healthy sample, respectively (cf. Ritsner et al., 2005 ). Test/C0Retest Test/C0retest correlations (intraclass correlations /C0ICC; two-week interval) of the Q-LES-Q scores of 54 outpati- ents with major depression disorder ranged from .63 for leisure activities to .89 for school/course work. However, actual sample size differed for the subscales (i.e., n56 for school/course work; n539 for work; n552 for household duties; remaining scales N554). Furthermore, test /C0retest reliability for the basic Q-LES-Q (and the Q-LES-Q-18) was examined in a sample of 33 randomly selected outpatients and 35 healthy individuals who completed the Q-LES-Q twice within a two-week interval. The ICCs of the General QOL Index were .91 and .90 for the Q-LES-Q and the Q-LES-Q-18 in outpatients, respectively as well as .87 and .86 in healthy subjects, respec- tively. The subscales showed ICCs ranging from .79 to .87 in the basic Q-LES-Q and from .71 to .83 in the Q-LES- Q-18 for both the outpatients and the healthy sample.116 5. MEASURES OF LIFE SATISFACTION ACROSS THE LIFESPAN II. EMOTIONAL DISPOSITIONS
Validity Convergent/Concurrent In the inpatient sample, positive correlations between the corresponding scales of the basic Q-LES-Q and its abbreviated version (Q-LES-Q-18) were r5.97 for the General QOL Index, r5.96 for leisure time activities, r5.95 for subjective feelings, r5.95 for social relationships, and r5.93 for physical health ( Ritsner et al., 2005 ). The Quality of Life Scale (QLS; Heinrichs, Hanlon, & Carpenter 1984 ) scores of outpatients significantly corre- lated with the General QOL Index and the subscales of the basic Q-LES-Q ( r5.55 to r5.64) and the abbreviated Q-LES-Q-18 ( r5.51 to r5.64;Ritsner et al., 2005 ). Divergent/Discriminant Correlational analyses between the Q-LES-Q and various depression measures revealed small to moderate negative correlations ( Endicott et al., 1993 ). For example, the Q-LES-Q total score correlated negatively with the Beck Depression Inventory (r52.36;Beck & Beamesderfer, 1974 ). Also, the general index of the Q-LES-Q-18 exhib- ited negative associations with measures of depression ( r52.29 with the Montgomery and Asberg Depression Rating Scale ;Montgomery & Asberg, 1979 ), negative symptoms ( r52.19 with the Positive and Negative Syndrome Scale ;Kay, Fiszbein, & Opler 1987 ), and general psychopathology ( r52.28 with the Positive and Negative Syndrome Scale )(Ritsner et al., 2005 ).Ritsner et al. (2005) showed that the means of the basic Q-LES-Q (general activities subscale excluded) and the Q-LES-Q-18 differed between inpatients and healthy participants as well as between subgroups of the inpatients. Healthy participants always obtained higher scores on the General QOL Index and subscales than did inpatients. Schizophrenic patients were less satisfied with their social relationships than patients with a mood/schizoaffective disorder, but did not differ in their levels of satisfaction on any of the other subscales or the General QOL Index (Ritsner et al., 2005 ).Endicott et al. (1993) reported negative correlations between the Q-LES-Q and the Clinical Global Impressions Severity of Illness Ratings (NIMH, 1985 ), ranging from r52.51 (social relationships) to r52.68 (subjective feelings). Construct/Factor Analytic Ritsner et al. (2005) presented results of an exploratory principal components analysis performed on the inter- correlations of the Q-LES-Q-18 items. Four components were extracted (with eigenvalues $1) which were sub- jected to varimax rotation and subsequently labeled social relationships, physical health, subjective feelings, and leisure time activities. The hypothesized fifth general activity dimension could not be replicated and was there- fore not included in the Q-LES-Q-18 measure. Criterion/Predictive Predictive validity of the Q-LES-Q and Q-LES-Q-18 measures has been summarized in Ritsner et al. (2005) . Location Endicott, J., Nee, J., Harrison, W., & Blumenthal, R. (1993).

Quality of Life Research, 14, 1693/C01703. Results and Comments The Q-LES-Q and its abbreviated form (i.e., the Q-LES-Q-18) are multidimensional measures of life satisfaction for adults that contain multiple items for each domain. Studies of the Q-LES-Q and the Q-LES-Q-18 suggested satisfactory item homogeneity, test /C0retest reliability, and evidence of validity. These measures appear to have good usefulness in clinical (i.e., psychiatric) settings, and they are also suitable for use with healthy people. However, further studies of the psychometric properties of the measures in different populations (e.g., older adults, psychiatric patients other than schizophrenics, and patients with schizoaffective and mood disorders) are needed to assess the range of applicability of the Q-LES-Q and the Q-LES-Q-18.117 OVERVIEW OF THE MEASURES II.

Reproduced with permission. Life Satisfaction Index for the Third Age (LSITA) (Barrett & Murk, 2006 ) Variable Barrett and Murk (2006) aimed at measuring the life satisfaction of older people referring to individuals’ eva- luations of their general feelings of well-being to identify ‘successful’ aging. They defined life satisfaction as a latent construct consisting of five major components: (a) z est vs. empathy (i.e., enthusiasm of response to life in general, independent of type of activity); (b) resolution and fortitude (i.e., active acceptance of personal responsibil- ity for one’s own life); (c) congruence between desired and achieved goals (i.e., believing that major goals have been achieved); (d) self-concept (i.e., being concerned with one’s appearance, judging oneself as wise and competent, and not feeling old); and (e) mood tone (i.e., positive affective responses, like happiness and optimism). Description The LSITA is a 35-item self-rating questionnaire (zest vs. apathy: 7 items; resolution and fortitude: 9 items; congruence of goals: 5 items; self-concept: 5 items; mood tone: 9 items) utilizing a 6-point Likert-type response format (ranging from 1 5strongly disagree to 65strongly agree ). Twenty of the LSITA items were derived from an earlier measure of life satisfaction in older people ( Life Satisfaction Index , LSI; Neugarten, Havighurst, & Tobin 1961). Additionally, Barrett and Murk expanded the former LSI to include 15 new items that reflected each of the118 5. MEASURES OF LIFE SATISFACTION ACROSS THE LIFESPAN II. EMOTIONAL DISPOSITIONS
five postulated components of life satisfaction. A panel of experts provided support for the content validity of the items. Five domain scores and a total score are created by summing the related item responses (15 items are reverse keyed). Sample Barrett and Murk (2006) reported data from 654 participants, all of whom were 50 years of age or older. These adults, all within their ‘third age’ (i.e., seniors), were Midwestern US adults acquired at third age learning events, retirement centers, church events, community centers, and from the general public. In this sample, the five domains exhibited mean scores for zest vs. apathy ( M530.5, SD55.2), resolution and fortitude ( M539.4, SD54.8), congruence of goals ( M522.2, SD53.0), self-concept ( M525.2, SD53.3), and mood tone ( M532.9, SD56.3) as well as the total score ( M5151.0, SD519.5) ( Barrett, 2006 ). Reliability Internal Consistency Barrett and Murk (2006) reported Cronbach alpha coefficients ranging from α5.56 to α5.84 for the five domains. The LSITA total score yielded an alpha coefficient of α5.93. Test/C0Retest No test /C0retest reliability coefficients have been reported to-date. Validity Convergent/Concurrent The LSITA scores correlate positively with the Salamon-Conte Life Satisfaction in the Elderly Scale (SCLSES; Salamon & Conte, 1984 ). For example, Barrett and Murk (2006) reported a correlation of r5.78 between the total scores of the LSITA and SCLSES. The corresponding domain scores showed correlations between r5.56 (LSITA congruence of goals /C0SCLSES goals) and r5.75 (LSITA zest vs. apathy /C0SCLSES daily activities). The correla- tion between the LSITA and the SWLS ( Diener et al., 1985 ) also exceeded r5.50 (Barrett & Murk, 2006 ). Divergent/Discriminant No discriminant validity coefficients have been reported to-date. Construct/Factor Analytic A confirmatory factor analysis of the LSITA was carried out at the domain level and showed that the five domains were well represented in a one-factor solution (e.g., CFI 5.94, NFI 5.94) ( Barrett & Murk, 2006 ). Loadings ranged from .68 (congruence of goals) to .89 (mood tone). Criterion/Predictive Criterion validity evidence for the LSITA has been reported in Barrett and Murk (2006) . Location Barrett, A.

St. Louis, MO: University of Missouri, St. Louis. Results and Comments Although Barrett and Murk (2006) devised 15 new items that reflected each of the five postulated components of life satisfaction, the LSITA appears to be a unidimensional measure of life satisfaction for elderly people. Including the aspects of zest vs. apathy suggests that the LSITA is not strictly a measure of life satisfaction, but also incorporates affective components. The preliminary results of the LSITA reported by Barrett and Murk (2006) indicated good item homogeneity for the total LSITA, and the domains (except for the self-concept domain). Although there is evidence for the convergent validity of the LSITA total and domain subscales in elderly samples, the research base for the LSITA is limited. Future studies are needed to assess its test /C0retest reliability, factor structure at the item level, and validity.119 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS

Students’ Life Satisfaction Scale (SLSS) (Huebner, 1991b ) Variable Huebner (1991b) constructed the SLSS for the assessment of satisfaction with life as a whole, based on Diener’s (1984) conceptualization of global life satisfaction. Description The SLSS, a self-report measure for 8 to 18-year-old children and adolescents, is composed of seven items (two of them are reverse keyed). To facilitate judgments of life overall, items were written to be domain-free in nature (e.g., ‘I have a good life’ instead of ‘I have a good family life’). The items were designed to be simple and easy to read, and thus, to be appropriate for students representing a wide range of ages and intellectual abilities. Whereas in early studies (e.g., Huebner, 1991b ), the SLSS used a 4-point answer format ranging from 1 5never to 45always , the current form uses a 6-point Likert-type response format ranging from 1 5strongly disagree to 65strongly agree (cf.Huebner, Suldo, & Valois 2005 ).120 5. MEASURES OF LIFE SATISFACTION ACROSS THE LIFESPAN II. EMOTIONAL DISPOSITIONS
Sample Huebner (1991b) reported findings for a sample consisting of a total of 329 children aged 8 to 14 years. Utilizing the 4-point response format, the mean of the SLSS (sum of 7 items) was found to be 20.84 ( SD54.51). Using a larger sample of 1,188 adolescents, Huebner et al. (2005) reported a mean of the SLSS (averaged over 7 items) of 4.21 ( SD51.14; utilizing the 6-point response format). Reliability Internal Consistency The 7-item SLSS exhibited a Cronbach alpha coefficient of α5.82 ( Huebner, 1991b ).Huebner et al. (2005) reported alpha coefficients ranging from α5.73 to α5.86 in all age groups (8 /C018 years). Test/C0Retest One- to two-weeks test /C0retest reliability of the SLSS was found to be rtt5.74 ( Huebner, 1991b ). Further research on test /C0retest stabilities yielded coefficients of rtt5.76 (1/C02 weeks), rtt5.64 (one month), rtt5.55 (4 months), rtt5.53 (one year), and rtt5.51 (2 years) (e.g., Huebner et al., 2005 ;Marques, Pais-Ribeiro, & Lopez 2011;Weber, Ruch, & Huebner 2013 ). Validity Convergent/Concurrent The SLSS total score revealed a positive correlation of r5.62 with the Andrews-Withey (1976) life satisfaction item, as well as correlations with measures of positive affect (e.g., Bradburn’s, 1969 , happiness item, r5.36; Happiness subscale of the Piers-Harris Children’s Self-Concept Scale ,Piers, 1984 ,r5.53; cf. Huebner, 1991b ). The SLSS also showed a positive relationship with the Piers-Harris total self-concept score (r5.53;Huebner, 1991b ). Dew and Huebner (1994) reported a positive correlation ( r5.58) between the SLSS and the Perceived Life Satisfaction Scale (PLSS; Adelman et al., 1989 ). Divergent/Discriminant Huebner (1991b) showed that the SLSS was not significantly associated with a social desirability response set (r5.05). Huebner et al. (2005) listed several more results on its discriminant validity, for example, the SLSS showed non-significant relationships with IQ and school grades ( Huebner & Alderman, 1993 ). Additionally, the SLSS as a measure of the cognitive component of subjective well-being was shown to be distinguishable from the affective components of subjective well-being utilizing conjoint factor analysis (cf. Huebner et al., 2005 ).Huebner (1991c) reported a negative correlation between SLSS and a measure of anxiety ( r5/C0.51; Revised Children’s Manifest Anxiety Scale ,Reynolds & Richmond, 1985 ). Construct/Factor Analytic Huebner (1991b) computed a principal components analysis (extraction criterion was eigenvalues .1), and found that the first unrotated principal component accounted for most of the variance. Unidimensionality of the SLSS has been reported in several studies (for a review see Huebner et al., 2005 ). Criterion/Predictive Predictive validity evidence for the SLSS has been reported by Huebner (1991a) . Also, Huebner et al. (2005, p. 50) reported that, ‘Predictive validity studies suggest that the SLSS predicts important mental health behaviors independently and interactively with measures of stressful life events.’ Location Huebner, E. S. (1991b). Initial development of the Students’ Life Satisfaction Scale. School Psychology International ,12, 231/C0240. Results and Comments Research on the SLSS has provided support for its reliability and validity as a measure of global life satisfac- tion in children and adolescents aged between 8 and 18 years, covering elementary, middle, and high school stu- dents. The SLSS has been evaluated in studies in several nations (e.g., Germany, Portugal); however, additional cross-national studies are needed. Because professionals and researchers often require such a brief measure of121 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
global life satisfaction, the SLSS can be a useful assessment tool for applied professionals (e.g., screening pur- poses) and researchers in this field (e.g., large-scale assessments). Additional research on its sensitivity to chang- ing life conditions and interventions would be particularly beneficial.

Perceived Life Satisfaction Scale (PLSS) (Adelman et al., 1989 ) Variable The Perceived Life Satisfaction Scale (PLSS) was developed within the context of studying psychosocial pro- blems in young people of ages 8 to 18 years. As most of the prior research in this age group focused on dissatis- faction with school experiences in particular, the PLSS was developed to expand the range of children’s reports of their satisfaction or dissatisfaction with respect to additional major aspects of their daily lives (i.e., material and physical well-being, relationships, environment, personal development and fulfillment, and recreation and entertainment). Description The PLSS consists of 19 items that measure the degree of satisfaction/dissatisfaction with different facets of minors’ lives. The PLSS utilizes a 6-point response scale that needs to be converted when scoring for dissatisfac- tion of the respondents’ answers (i.e., low ratings, 1 and 2, are scored as 2; moderate ratings, 3 and 4, are rated as 1; high ratings, 5 and 6, are rated as 0). The PLSS scoring ranges between 0 (low dissatisfaction) and 38 (high dis- satisfaction) by summing all 19 items. Researchers have also calculated simple sums of items to create a total score (e.g., ranging from 1 5very dissatisfied to 65very satisfied ), yielding a total score of between 19 and 114, where higher scores represent higher life satisfaction (e.g., Huebner & Dew, 1993a,b ). Sample Four samples have been reported in Adelman et al. (1989) . Samples 1, 2, and 3 consisted of 221, 179, and 68 school students, respectively, with mean ages of 14.5 years, 13.2 years, and 12.9 years, respectively. Sample 1 was mostly represented by ethnic minorities (70%), while samples 2 and 3 were not (i.e., 16% and 13%, respectively). The fourth sample was a mental health sample consisting of students who were referred by their schools to a mental health center for treatment. It consisted of 47 children with a mean age of 11.1 years. About one fourth (24%) were represented by ethnic minorities. Twenty-five students showed emotionally based pervasive school behavior problems, 15 students showed underachievement, and seven students showed school avoidance. The means of the total PLSS were 8.6 ( SD55.9; sample 1), 7.0 ( SD54.1; sample 2), and 7.8 ( SD54.7; sample 3).122 5. MEASURES OF LIFE SATISFACTION ACROSS THE LIFESPAN II. EMOTIONAL DISPOSITIONS
The mean of the total PLSS in the mental health sample was 9.7 ( SD56.8), and was higher than all means of sample 1, 2, and 3 indicating that the mental health sample was more dissatisfied. In sample 1, and in the mental health sample, the older students were more likely to report higher dissatisfaction than the younger students (both rs5.33). In the mental health sample, girls scored more highly ( M512.8, SD58.2) than boys ( M58.4, SD55.7). Reliability Internal Consistency Huebner and Dew (1993a) reported a Cronbach alpha coefficient of α5.89 for the total scale in a sample of 222 students in grades 8 to 12 (mean age of 15.5 years, SD51.5). Test/C0Retest Adelman et al. (1989) reported a test /C0retest correlation of rtt5.85, without specifying the time interval. Validity Convergent/Concurrent The PLSS correlated positively ( r5.58) with the Students’ Life Satisfaction Scale (SLSS) ( Dew & Huebner, 1994 ). Adelman et al. (1989) reported that the PLSS correlated positively with depression levels ( Children’s Depression Inventory ;Adelman et al., 1989 ) in the mental health sample ( r5.55). Hence, students who reported higher dissat- isfaction reported more symptoms of depression. Huebner and Dew (1993a) reported that more satisfied students reported a higher general self-concept ( r5.48; assessed with SDQ-II; Marsh, 1988 ). PLSS scores correlated with parent-rated life satisfaction, showing a coefficient of r5.42 (Huebner & Dew, 1993a ).Smith, Adelman, Nelson, Taylor, and Phares (1987) showed that the PLSS is positively correlated ( r5.60) with control satisfaction (assessed with a single item; cf. Smith et al., 1987 ), but less so ( r5.35) with happiness (assessed with a single item; cf. Smith et al., 1987 ). Divergent/Discriminant The PLSS demonstrated a small inverse correlation of r52.29 with perceived control at school ( Perceived Control at School Scale ;Adelman et al., 1989 ). Construct/Factor Analytic Huebner and Dew (1993b) conducted a principal components analysis with a promax oblique rotation on the sample of 222 students resulting in a four-component solution showing that the PLSS provides multidimensional assessment of life satisfaction. Criterion/Predictive For psychologically disturbed children, PLSS scores correlated positively ( r5.55) with a child depression measure, and negatively ( r52.54) with expectations of improvement both at school and at home ( Bender, 1997 ). Location Adelman, H. S., Taylor, L., & Nelson, P. (1989). Minor’s dissatisfaction with their life circumstances. Child Psychiatry and Human Development ,20, 135/C0147. Results and Comments Research on the PLSS has provided preliminary information on its reliability and validity as a measure of dis- satisfaction/satisfaction in children and adolescents (aged 8 to 18 years) studying psychosocial problems in the general population and individuals with mental health problems. The PLSS is a promising measure. It was designed to assess general life satisfaction by evaluating satisfaction across a variety of life experiences. Nevertheless, although there is evidence for the usefulness of the total score, some research suggests that the PLSS is multidimensional in nature ( Huebner & Dew, 1993b ). Additional research is needed to clarify its psycho- metric properties, especially its dimensionality and test /C0retest reliability.123 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS

Multidimensional Students’ Life Satisfaction Scale (MSLSS) (Huebner, 1994 ) Variable The MSLSS was designed to provide a multidimensional assessment of children’s life satisfaction, for more focused diagnostic, prevention, and intervention efforts. The MSLSS provides a profile of young people’s satisfac- tion with important, specific domains (e.g., school, family, and friends) in their lives. Furthermore, a total score can be calculated to assess general, overall life satisfaction. The MSLSS has been developed for children and ado- lescents across a wide range of age (grades 3 /C012) and ability levels (e.g., children with mild developmental dis- abilities through gifted children). Description The MSLSS consists of 40 items assessing domain-specific satisfaction with family (7 items), friends (9 items), school (8 items), living environment (9 items), and self (7 items). Ten of the 40 items are reverse keyed. The items were designed to be simple and easy to read, and thus, to be adequate for a wide range of age and intellectual ability. Whereas in early studies (e.g., Huebner, 1994 ), the MSLSS used a 4-point response format ranging from 15never to 45almost always , the current form uses a 6-point Likert-type response format ranging from 15strongly disagree to 65strongly agree (cf.Huebner, 2001 ). As the domains consist of unequal number of items, the five domain scores and the total score are created by summing the related item responses and dividing by the number of domain (or total) items. Sample Sample 1 ( N5312) consisted of grades 3 /C08 children having a mean age of 10.90 years. Sample 2 ( N5413) con- sisted of grades 3 /C05 children with a mean age of 8.97 years. Both samples used the 4-point response format. Sample 1 yielded domain-specific means for the subscales labeled: friends ( M53.31, SD50.57), family (M53.10, SD50.64), school ( M52.65, SD50.64), self ( M53.13, SD50.63), and living environment ( M53.11, SD50.62). Sample 2 yielded domain-specific means for the subscales labeled: friends ( M53.30, SD50.56), fam- ily ( M53.34, SD50.60), school ( M53.02, SD50.68), self ( M53.21, SD50.61), and living environment (M53.27, SD50.62) (cf. Huebner, 1994 ).124 5. MEASURES OF LIFE SATISFACTION ACROSS THE LIFESPAN II. EMOTIONAL DISPOSITIONS
Reliability Internal Consistency The MSLSS exhibited a Cronbach alpha coefficient of α5.92 for the total scale (in both samples), and alpha coefficients between α5.82 and α5.85 (sample 1), and between α5.78 and α5.83 (sample 2) for the domain- specific subscales ( Huebner, 1994 ). Test/C0Retest Test/C0retest coefficients for two- and four-week time periods have been reported falling mostly in the rtt5.70 tortt5.90 range (cf. Huebner, 2001 ). Validity Convergent/Concurrent Convergent validity was evaluated through the pattern of correlations between the MSLSS and a self-concept measure ( Self Description Questionnaire-I ;Marsh, 1990 ). For example, school-related and self-related self-concept measures were expected to show the highest correlations with the corresponding subscales of the MSLSS (i.e., school-related satisfaction, and self-related satisfaction), confirmed by correlations of r5.45 and r5.62, respectively ( Huebner, 1994 ). Also, the friends-related subscale of the MSLSS showed the highest correlation with another measure of satisfaction with friendships ( r5.56; Children’s Loneliness and Social Dissatisfaction Scale ; Asher, Hymel, & Renshaw 1984 ), and the school-related subscale of the MSLSS showed the highest correlations with a measure on quality of school life ( r5.68;Quality of School Life Scale ;Epstein & McPartland, 1977 ). Divergent/Discriminant The analyses also provided evidence for the discriminant validity of the MSLSS as lower coefficients with respect to non-targeted measures were also found (e.g., a correlation between satisfaction with friendships and school-related self-concept of r5.22). Likewise, the MSLSS friends-related subscale and the peer relations self-concept measure exhibited a modest correlation of r5.27 (cf. Huebner, 1994 ). Other validity evidence (e.g., correlations with parents and teachers reports, and measures of social desirability) was summarized by Huebner (2001) . Construct/Factor Analytic In sample 1, a principal components analysis with oblique rotation yielded a five-dimensional solution. This five-factorial solution explained 49.5% of the total variance. Huebner (1994) reported congruence coefficients of the solution in sample 1 with a solution computed for sample 2 showing coefficients of between .98 and .99, indicative of a very high degree of congruence between both solutions. Criterion/Predictive Predictive validity of a brief version of the MSLSS was investigated by Huebner, Antaramian, Hills, Lewis, and Saha (2011) who reported, for example, that the scale is longitudinally predictive of ‘multiple indices of stu- dents’ engagement in their schooling’ (p. 161). Location Huebner, E. S. (1994). Preliminary development and validation of a multidimensional life satisfaction scale for children. Psychological Assessment ,6, 149/C0158. Results and Comments Research has provided considerable evidence for the reliability and validity of the MSLSS with elementary, middle, and high school students. Children as young as 8 years of age appear to be able to differentiate satisfac- tion across important life domains. Measures of domain-based life satisfaction are thus expected to complement global measures, providing more nuanced measures of subjective quality of life for research and practice purposes (e.g., counseling). Some cross-cultural validation research has been done (e.g., Gilman et al., 2008 ). Nevertheless, additional validation studies are needed to determine its meaningfulness in other nations. Recently, an abbreviated version of the MSLSS has been presented ( Huebner, Zullig, & Saha 2012 ), which con- sists of 30 items, excluding the 10 reverse keyed items from the original MSLSS ( Huebner, 1994 ). Although the research is limited, this abbreviated version showed a good fit with the expected factor structure and promising125 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
reliability ( Huebner et al., 2012 ). Furthermore, a promising 5-item measure exists, the Brief Multidimensional Students’ Life Satisfaction Scale (BMSLSS; Seligson, Huebner & Valois 2003 ), which assesses domain-specific satis- faction with family, friendships, school experiences, self, and living environment with one item for each domain.

FUTURE RESEARCH DIRECTIONS The breadth and depth of life satisfaction measures available has increased considerably over the last several decades. A variety of measures now exist that offer reliable methods for assessing a person’s cognitive judgments of their quality of life for different age groups, different clinical populations, using a variety of formats (top down vs. bottom up; unidimensional vs. multidimensional; brief vs. comprehensive). Most of these scales have been published since Andrews and Robinson’s (1991) contribution to the previous edition of this text, reflecting a significant expansion of measures and corresponding research to the literature base. The measures reviewed within this chapter vary in the number and quality of reliability and validity studies; however, all have provided some level of research evidence supporting their use for various purposes, especially research purposes. Research to date suggests that the measure with the most reliability and validity evidence across college-age, middle-age, and senior adults of adult global life satisfaction, for use with the general popula- tion is the SWLS. Multidimensional measures of life satisfaction show promising reliability and validity evidence126 5. MEASURES OF LIFE SATISFACTION ACROSS THE LIFESPAN II. EMOTIONAL DISPOSITIONS
(e.g., ESWLS, Q-LES-Q[-18], QLI, PWI, TSWLS), with many offering global and domain-specific information. Some of these measures were designed to assess specific age groups (e.g., LSITA), specific clinical populations (e.g., Q-LES-Q[-18]), and/or have been expanded into different versions to provide a more nuanced assessment of specific clinical populations (e.g., QLI). Many of these measures have been translated into various languages and used internationally, especially the SWLS. A recent summary of the overall status of life satisfaction measure- ment research, focusing on adults, has been completed by Diener et al. (2013) . The development of life satisfaction measures for youth has been a notable area of progress. A number of mea- sures have been developed to assess life satisfaction for youth aged 8 /C018 years and many of the adult life satis- faction measures have been adapted for youth (e.g., SWLS-C, PWI-SC). Some initial attention has been given to the development of measures targeting younger populations (e.g., PWI-PS); however, given the challenge involved in obtaining subjective perceptions of young children, more research is needed investigating the validity and utility of such measures. The measurement of subjective well-being in young children (age 8 years and under) remains a key area of opportunity for research. Youth measures include global and multidimensional assessments of life satisfaction, and extensive work has demonstrated the reliability and validity of many of these measures, especially the SLSS and MSLSS ( Proctor, Linley, & Maltby 2009a ). As with adult measures, much work remains in further establishing the psychometric evidence for many of these measures, especially across cultures (cf.Casas et al., 2012 ). Recent reviews of youth life satisfaction measures are available ( Huebner & Hills, 2013; Proctor, Linley, & Maltby 2009b ). Consistent with Andrews and Robinson’s (1991) recommendation, most life sat- isfaction measures developed in the last two decades incorporate a scale with five or more response categories. Competing criteria should also be considered that include age and functional capacity of the participants. For a current review see Diener et al. (2013) . It is important to understand the different factors found to influence life satisfaction depending on context (e.g., culture, age) in order to make an informed decision in selecting an appropriate measure. For example, although the SWLS is an internationally used, empirically supported measure of well-being, the PWI has been used extensively in Australian populations. Substantial progress has been made in the development of life satisfaction measures for adults, youths, and specific clinical populations. Research over the past two decades has increased our understanding of the relation- ship between life satisfaction and the social and psychological factors that influence satisfaction across the life- span ( Lyubomirsky et al., 2005; Proctor et al., 2009a ). Further, such research has laid the groundwork for investigating appropriate causal models of well-being. The usefulness of life satisfaction measures has gained attention at the macro-applied level of social policy- making and many countries have expanded their use of these measures in understanding social impact (International Wellbeing Group, 2013 ). National accounts of subjective well-being (including life satisfaction mea- sures) for children and adults are being considered and adopted by various nations. This will also provide the opportunity to investigate the psychometric properties and utility of life satisfaction measures in different con- texts. Given the widespread international interest in national accounts of well-being, perhaps the greatest need for future research involves studies of the comparability of reliability, construct validity, and predictive validity of different life satisfaction measures across different groups, such as nations, cultures, ethnic groups, genders, and age groups (see Gilman et al., 2008 ). Research into the usefulness of life satisfaction measures in the public policymaking arena is also essential. The progress made to-date in the development and validation of measures of life satisfaction is commendable, and future research expanding the reliability/validity evidence for use of these measures within general and spe- cific populations will aid in continuing to resolve many of the questions that remain in understanding the nature and impact of satisfaction across the lifespan.

EMOTIONAL DISPOSITIONS
CHAPTER 6 Measures of Self-Esteem M. Brent Donnellan1, Kali H. T rzesniewski2and Richard W . Robins3 1Michigan State University, East Lansing, MI, USA;2University of California, Davis, CA, USA; 3University of California, Davis, CA, USA Self-esteem is one of the most widely studied constructs in the social sciences as it unites basic and applied researchers from psychology to education to sociology (see e.g., Donnellan, Trzesniewski, & Robins, 2011 ; Robins, Tracy, & Trzesniewski, 2008a ;Robins, Trzesniewski, & Schriber, 2008b ;Zeigler-Hill, 2013 ). It is also one of the oldest constructs in scientific psychology as it was first described by William James (see e.g., 1985/1892). In light of these two facts, it is perhaps unsurprising tha t self-esteem is one of the more controversial constructs in literature. There are ongoing debates about the caus al role of self-esteem for life outcomes, the degree to which self-esteem is a cultural universal as opposed to a construct limited to Western/individualistic cultures, as well as disagreement over whether self-esteem is more trait-like or state-like (see Donnellan et al., 2011 ). In light of these debates, the assessment of self-esteem is an important and even critic al issue because measure- ment lies at the heart of empirical research. According ly, the focus of this chapter is to update and extend pre- vious work detailing the assessment of self-esteem by Blascovich and Tomaka (1991) and Heatherton and Wyland (2003) . James (1985/1892) specified that self-esteem is ‘determined by the ratio of our actualities toour supposed potentialities ’ (italics added, p. 54). Subsequent treatments emphasize that self-esteem involves feelings of self- acceptance and self-respect (e.g., Rosenberg, 1989 ). In a nutshell, self-esteem is the subjective assessment of one’s worth as a person. If someone feels good about herself then she is said to have high self-esteem, whereas someone who feels badly about herself is said to have lo w self-esteem. These self-eva luations need not be tied to objective standards because the critical element o f the construct is the subjective evaluation. Self- evaluations can occur with respect to specific domain s, such as athletics and physical appearance, or at the general level in terms of an overarching evaluation of t h es e l fa saw h o l e .T h ef o r m e rc a s er e f e r st od o m a i n specific self-evaluations (or domain specific self-est eem) whereas the latter refers to global or general self- esteem. Given the subjective nature of the construct, self-este em is typically assessed with self-report scales. There are apparently many different self-esteem measures and one review article even suggested a figure of 200 (Sheff & Fearon, 2004 ). However, most of these measures are used in frequently and the current research litera- ture in mainstream journals largely consists of studies based on a relatively small set of commonly used instru- ments. Indeed, the previous version of this chapter by Blascovich and Tomaka (1991) reviewed just 11 measures of self-esteem and closely related constructs . They concluded that the Ros enberg Self-Esteem scale (RSE; e.g., Rosenberg, 1989 ) was the most popular measure of the construct as it accounted for at least 25% of all citations to self-esteem measures in major journa ls. The next closest measure accounted for around 18% of citations, whereas none of the other measures accounted for more than 10% of the total citations to self-esteem measures. In other words, a small set of measures accou nted for the majority of citations related to the assess- ment of self-esteem. We conducted an analysis similar to the one performed by Blascovich and Tomaka (1991) to estimate the prevalence of citations to different self-esteem measures. Results are displayed in Table 6.1 . The continued 131Measures of Personality and Social Psychological Constructs. DOI: http://dx.doi.org/10.1016/B978-0-12-386915-9.00006-1 ©2015 Elsevier Inc. All rights reserved.
prominence of the Rosenberg scale continues through 2 013. We suspect that for many researchers, the RSE is the standard measure of global self-esteem. In light of the importance of this scale, we will summarize recent work on this measure, in addition to covering several other measures that were either not yet developed (e.g., the single item self-esteem scale; Robins, Hendin, & Trzesniewski, 2001a ;R o b i n s ,T r a c y ,T r z e s n i e w s k i , Potter, & Gosling, 2001b ) or not well-covered by the Blascovich and Tomaka (1991) chapter, such as the Harter scales (e.g., Harter & Pike, 1984 ) and the Self-Description Questionnaires (e.g., Marsh, 1992a,b ;s e ea l s o Boyle, 1994 and Byrne, 1996 ). Readers interested in reviews of measures not reported here should consult Blascovich and Tomaka (1991) orHeatherton and Wyland (2003) . In total, we review the five measures listed below. The first three are global self-esteem measures and th e last two are domain-specific inventories that also include a general or global scale.

MEASURES OF SELF-ESTEEM II. EMOTIONAL DISPOSITIONS
MEASURES REVIEWED HERE 1.The Rosenberg Self-Esteem Scale ( Rosenberg, 1989 ) 2.The Single-Item Self-Esteem Scale ( Robins et al., 2001a ) 3.Self-Liking and Self-Competence Questionnaires (e.g., Tafarodi & Swann, 1995 ) 4.The series of Harter Self-Perception Profiles (e.g., Harter & Pike, 1988) 5.The series of Self-Description Questionnaires (e.g., Marsh, 1992a ) OVER VIEW OF THE MEASURES Our goal in this chapter is to help researchers make informed decisions when selecting measures of self- esteem for their own research and when evaluating the existing literature. Thus, the current chapter reviews some of the most widely used self-report measures in the literature. We first provide a review of the Rosenberg Self-Esteem Scale (RSE) /C0(Rosenberg, 1989 ) with material updated since the Blascovich and Tomaka (1991) chap- ter, given the ongoing popularity of this instrument. In particular, we summarize new data on the correlates of the RSE and describe debates about the factor structure of this instrument. We then describe the psychometric properties of a popular single-item self-esteem measure, the Single-Item Self-Esteem Scale (SISE; Robins et al., 2001a ). This measure was designed to approximate the RSE and is useful when researchers have very limited time to assess global self-esteem. We then describe the Self-Liking and Self-Competence Scale /C0Revised (SLSC-R; Tafarodi & Swann, 1995, 2001 ). This instrument provides a way to separately assess perceptions of self-worth (i.e., self-liking) from perceptions of personal efficacy and self-regard of one’s capabilities (i.e., self-competence). We conclude the chapter by reviewing two of the mostly widely used multiple domain inventories /C0the series of Self-Perception Profiles developed by Harter (e.g., Harter & Pike, 1988) and the series of Self-Description Questionnaires developed by Marsh (e.g., Marsh, 1992a,b ; see also the comprehensive reviews by Boyle, 1994 ; andByrne, 1996 ). Both of these measures include an overall global scale as well as scales designed to assess per- ceptions of self-worth relevant for individuals at different developmental periods (e.g., childhood, adolescence, and young adulthood). We will not cover measures of implicit self-esteem in this chapter. Implicit self-esteem refers either to: (1) an automatic and preconscious self-evaluation that is distinct from explicit self-esteem (i.e., the construct assessed by self-report measures); or (2) feelings of self-worth that individuals are unwilling or unable to disclose on self- report measures (see Buhrmester, Blanton, & Swann, 2011 ). The first account suggests two distinct constructs /C0 implicit versus explicit self-esteem, whereas the second account of implicit self-esteem suggests the need for alternative measurement techniques to self-report scales. The two prominent measures of implicit self-esteem are the Implicit Association Test (IAT; e.g., Greenwald & Farnham, 2000 ) and the Name-Letter Test (NLT; Nuttin, 1985 ; see also Koole, Dijksterhuis, & van Knippenberg, 2001 ). These two scales are only weakly corre- lated with each other ( r5.08 from a meta-analysis of nine studies in Buhrmester et al., 2011 ) and the fact that the two implicit measures do not strongly converge seems problematic because it suggests that the two implicit measures do not capture the same underlying attribute. Likewise, questions have been raised about the criterion-related validity of implicit self-esteem measures ( Buhrmester et al., 2011 ). Moreover, neither of these two measures are strongly correlated with explicit measures of self-esteem (e.g., the meta-analytic correlation between the IAT and the RSE was .13 based on 11 studies summarized in Hofmann, Gawronski, Gschwendner, Le, & Schmitt, 2005 ) and the meta-analytic correlation between the Name-Letter Test and the RSE was only .12 [based on 19 studies summarized in Krizan & Suls, 2008 ] (see Buhrmester et al., 2011 ). Thus, we believe it would be premature to review implicit measures in light of the ongoing issues in the literature. Additional details about the measurement of implicit self-esteem can be found in Buhrmester et al. (2011) and Bosson, Swann, and Pennebaker (2000) . A quick and accessible primer on the IAT is found in Robins et al. (2008a,b) . We return to the importance of developing implicit measures of self-esteem in our final discussion of future research directions. Rosenberg Self-Esteem Scale (RSE) (Rosenberg, 1989 ).133 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
Variable Rosenberg (1989) defined global self-esteem as the overall attitude one holds about oneself, ranging from nega- tive to positive. High self-esteem entails the belief that one is ‘good enough’ whereas low self-esteem is associated with self-rejection and a general lack of self-respect. Description According to Blascovich and Tomaka (1991, p. 121) : The 10 items that make up the Rosenberg Self-Esteem Scale [RSE] were designed to optimize ease of administration, economy of time, unidimensionality, and face validity. Self-Esteem Scale items require the respondent to report feelings about the self directly. Although originally designed as a Guttman-type scale, the [RSE] is typically scored using a four-point response format (strongly agree, agree, dis- agree, strongly disagree) resulting in a scale range of 10 /C040 with higher scores representing higher self-esteem. Some authors, however, have adopted more familiar Likert-type response formats employing 5- or 7-point scales resulting in broader ranges of [RSE] scores. While contemporary investigators typically use the 10 Rosenberg items with a 4-point rating scale ( Heatherton & Wyland, 2003 ), it is also common for researchers to add a neutral response option and thus use a 5-point Likert-type response scale (e.g., Donnellan, Kenny, Trzesniewski, Lucas, & Conger, 2012 ;Gray-Little, Williams, & Hancock, 1997). Other response options have also been reported in the literature (see discussion pertaining to number of response scale points in Chapter 1, this volume). Sample Details of the original sample ( N55,024) used in the construction of the RSE were provided in Blascovich and Tomaka (1991, p. 121) . Subsequently, Schmitt and Allik (2005) investigated the psychometric properties of the RSE in several countries using samples ranging from N559 (Cyprus) to N52,782 (United States) with a combined sample of N516,998 (see below). Sinclair et al. (2010) also administered the RSE online to a sample ofN5503 respondents (see below). Even larger combined samples have been reported in the literature (e.g., N520,332; Rosenthal, Matthew Montoya, Ridings, Rieck, & Hooley, 2011 , see below). Reliability Internal Consistency Cronbach alpha coefficients for the RSE are usually above .80 and values above .90 have been reported in the literature ( Heatherton & Wyland, 2003 ). For example, Gray-Little et al. (1997) reported an alpha coefficient of .88 for a sample of 1,234 college students. Likewise, Zeigler-Hill (2010) reported an alpha coefficient of .88 for a sam- ple of 1,422 university students. Schmitt and Allik (2005) administered the RSE to participants from 53 countries and reported alpha coefficients ranging from .45 (Democratic Republic of the Congo; N5183) to .90 (Israel and the United Kingdom; N5389 and N5480, respectively). The average alpha coefficient was .81 (total N516,998). Sinclair et al. (2010) collected data from an internet sample designed to match the population of the United States and reported an alpha coefficient of .91 ( N5503). Test/C0Retest Ackerman and Donnellan (2013) reported a two-week test /C0retest reliability coefficient of .80 ( N5143 univer- sity students). Donnellan and McAdams (2013) reported a stability coefficient of .69 for a sample of college stu- dents assessed initially in the middle of their first semester and then again in the middle of their second semester (N5347). Donnellan et al. (2012) reported even higher stability coefficients for individuals aged in their early 30s assessed over a two-year span ( r5.77,N5399). Recently, Kuster and Orth (2013) suggested that the long- term stability coefficient for items from the RSE is around .40 for intervals approaching up to 30 years, based on a sample of 3,180 participants. All of these findings suggest that the RSE captures variance related to a reasonably stable individual difference construct (cf. Donnellan et al., 2012 ;Trzesniewski, Donnellan, & Robins, 2003 ). Validity Convergent/Concurrent Zeigler-Hill (2010) reported a positive correlation of .71 with the State Self-Esteem Scale ( Heatherton & Polivy, 1991). He also reported that the RSE was strongly associated with both the Self-Liking ( r5.90) and Self- Competence ( r5.71) scales developed by Tafarodi and Swann (2001) . The RSE correlated with the Harter global subscale .74 and .75 ( Donnellan, Trzesniewski, Conger, & Conger, 2007 ; Ferrier et al., 2008). Buhrmester et al. (2011)134 6. MEASURES OF SELF-ESTEEM II. EMOTIONAL DISPOSITIONS
suggested that the RSE converges so highly with other global measures of self-esteem like the Self-Liking and Self- Competence scales from Tafarodi and Swann (2001) that they can be combined into a single composite variable cap- turing explicit self-esteem ( Buhrmester et al., 2011 , p. 369). Thus, there is good evidence that several of the well- used global measures of self-esteem in the literature are highly interrelated. The RSE also correlates positively with informant reports of life-satisfaction and pleasant affect ( r5.42 and r5.39,N5141; Schimmack & Diener, 2003). Likewise, Buhrmester et al. (2011) reported that rater evaluations of global self-esteem are associated with explicit self-esteem ( r5.45). Self-esteem is positively correlated with psychological well-being and life satisfaction. These coefficients range from .30 to .60 or higher (e.g., Buhrmester et al., 2011 ;Robins et al., 2001a ;Rosenthal et al., 2011). For example, Sinclair et al. (2010) reported that the RSE correlates .51 with the mental health component of the SF-8 Health Survey ( Ware, Kosinski, Dewey, & Gandek, 2001 ). Scores on the RSE correlate positively with a measure of extraversion (e.g., r5.38;Robins et al., 2001a ;Schmitt & Allik, 2005 ;Watson, Suls, & Haig, 2002 )a n d this association remains relatively unchanged when controlling for social desirability ( Robins et al., 2001b ). Divergent/Discriminant RSE scores correlate negatively with measures of depression. For example, Sinclair et al. (2010) reported that the RSE correlated 2.62 with the 7-item depression scale from the Depression Anxiety Stress scales ( Lovibond & Lovibond, 1995 ). Likewise, scores on the Rosenberg are negatively correlated with measures of neuroticism (e.g., r52 .50; Robins et al., 2001a ; see also Judge, Erez, Thoresen, & Bono, 2002 ;Rosenthal et al., 2011 ; Watson et al., 2002 ). Although the causal relationship between self-esteem and aggression is contentious (e.g., Baumeister, Campbell, Krueger, & Vohs, 2003 ;Donnellan, Trzesniewski, Robins, Moffitt, & Caspi, 2005 ), scores on the RSE are negatively correlated with self-reports of aggression and anger (meta-analytic r52 .29 based on 8 studies; N520,332; Rosenthal et al., 2011 ). While RSE scores correlate positively with some global measures of nar- cissism ( #.30) ( Trzesniewski, Donnellan, & Robins, 2008 ); importantly, the RSE exhibits a small negative correlation with elements of narcissism related to entitlement and exploitativeness (meta-analytic r52 11,Rosenthal et al., 2011;s e ea l s o Ackerman & Donnellan, 2013 ). One interpretation is that self-esteem is more strongly related to adap- tive rather than maladaptive components of narcissism. This is consistent with Rosenberg’s contention that global self-esteem is distinct from the sense that one feels better than others (see Donnellan et al., 2005 ;2011). Also, scores on the RSE are largely distinct from academic outcomes and socioeconomic status ( Blascovich & Tomaka, 1991 ). Construct Factor Analytic There is ongoing discussion about the underlying factor structure of the RSE with proposed solutions ranging from one to five factors (see e.g., Corwyn, 2000 ;DiStefano & Motl, 2006 ;Gana et al., 2013 ;Greenberger, Chen, Dmitrieva, & Farruggia, 2003 ;Marsh, 1996 ;Marsh, Scalas, & Nagengast, 2010 ;Quilty, Oakman, & Risko, 2006 ; Supple, Su, Plunkett, Peterson, & Bush, 2012 ;Tafarodi & Milne, 2002 ). For example, Tafarodi and Milne (2002) reported a 5-factor model using data from 836 Canadian university students, whereas Quilty et al. (2006) found support for a 3-factor model using data from 503 Canadian university students and another sample of 501 adults from Oregon. DiStefano and Motl (2006) also found support for a 3-factor model using data from 757 university students from the United States. The basic concern is whether the RSE assesses a unidimensional construct or a number of conceptually distinct latent factors. This issue is important given that the vast majority of research with the RSE is based on composite scores which are basically the sums (or averages) of the responses to the 10 items. This strategy may be inappropriate if the items assess multiple substantive factors. The Rosenberg Self-Esteem Scale table below provides a key to the major solutions for the RSE. While this is currently a contentious area of psychometric research, at least two consistent results are emerging from this literature. First, the 5-factor model proposed by Tafarodi and Milne (2002) is difficult to fit to real data (Marsh et al., 2010 ;N52,213 10th graders from the United States). Tafarodi and Milne fit a model that included five latent factors labeled: global self-esteem, a positive method factor, a negative method factor, an assessment factor, and an acceptance factor. Assessment refers to items that involve content related to self-evaluation whereas acceptance refers to items with content that appear to capture feelings of self-acceptance ( Tafarodi & Milne, 2002 , p. 448). These two latent factors correspond to the conceptual attributes of self-competence and self-liking, respec- tively (see the discussion of the Self-Liking/Self-Competence Scale). Despite any conceptual appeal of these two dimensions, the psychometric issue is that the 5-factor model for the RSE proposed by Tafarodi and Milne does not appear to replicate well according to the published literature. Second, models that specify one general factor and two method factors capturing the positively keyed and nega- tively keyed items tend to fit the observed data better than alternatives such as a single-factor model or a 2-factor model ( DiStefano & Motl, 2006; Gana et al., 2013; Marsh et al., 2010; Quilty et al., 2006 ). Specifically, there is emerging135 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
evidence from factor analytic studies showing a single substantive general global factor and two seemingly stable response style tendencies, one capturing variance associated with the negatively keyed items and a second cap- turing variance associated with positively keyed items. However, research also suggests that a single global self- esteem factor explains a considerable amount of variance in the RSE items (e.g., Donnellan et al., 2012 ;Schmitt & Allik, 2005 ). Indeed, Tafarodi and Milne (2002) noted that a ‘common factor accounted for the lion’s share of reliable variance across the [RSE] items’ (p. 456) even when they could fit a complicated 5-factor model. This may suggest that the RSE items assess an essentially unidimensional construct (see Slocum-Gori, Zumbo, Michalos, & Diener, 2009 ). [To facilitate additional research, we have prepared an Mplus script (that specifies various factor models for the RSE) that can be obtained upon request. This script assumes that the ordering of the RSE items follows the order presented in the Blascovich and Tomaka (1991) chapter (see their p. 123) and the item order listed in this chapter.] Criterion/Predictive Several longitudinal studies have evaluated the predictive validity of scores on the RSE or scores on a subset of items from the RSE. For example, Trzesniewski et al. (2006) found that z-scores on the RSE (averaged across ages 11, 13, and 15 years) predicted adult outcomes including mental health problems, such as major depressive disorder (Odds Ratio 51.21) and adult anxiety disorder (Odds Ratio 51.45), as well as adult criminal convic- tions for violent offenses (Odds Ratio 51.25). Trzesniewski et al. also found that low adolescent self-esteem pre- dicted informant-reported work problems ( β5.13). Many of the findings of Trzesniewski et al. have held up in more recent analyses using cross-lagged modeling strategies that also control for prior levels of an outcome when considering predictive statistical effects for the RSE. For example, Kuster, Orth, & Meier (2013) found that self- esteem predicted future job satisfaction, controlling for previous levels (e.g. β5.13). Self-esteem also predicted future employment in a sample of 600 individuals (e.g. β5.17). Moreover, the results of Kuster et al. suggest that self-esteem was not consistently predicted by job conditions while controlling for previous levels of self- esteem (see also Orth, Robins, & Widaman, 2012 ). This finding places constraints on inferences about the strength of reciprocal relations between self-esteem and job conditions. In addition, scores on RSE positively predicted future levels of self-reported mental health such as depression ( β52 .20) and negative affect ( β52 .13) as well as self-reported physical health ( β52 .11) while controlling for prior levels using a data from over 1,800 participants enrolled in a long-term longitudinal study of multiple generations ( Orth et al., 2012 ). These authors also found that self-esteem predicted future job satisfaction ( β5.14). Thus, Orth et al. provided compelling evi- dence for the predictive validity of scores on the RSE for important life outcomes. The prospective effect of self-esteem on future depression has been replicated several times in reports from Orth, Robins, and Roberts (2008) ;Orth, Robins, and Meier, (2009a); Orth, Robins, Trzesniewski, Maes, and Schmitt (2009b) , and Orth et al. (2009a,b) . Indeed, a meta-analysis of 77 studies linking self-esteem and depres- sion suggested the same prospective effect of self-esteem on future depression ( Sowislo & Orth, 2013 ; meta- analytic estimate was β52 .16). Self-esteem is also prospectively linked with anxiety and there are some indications that this association is reciprocal ( Sowislo & Orth, 2013 ). The prospective meta-analytic effect captur- ing how strongly self-esteem predicted anxiety controlling for prior levels (i.e., a standardized regression coeffi- cient) was 2.10 whereas the prospective effect for anxiety predicting self-esteem was 2.08. The major caveat is that effect sizes tend to be modest (especially when controlling for prior levels of criterion-variables), a result that is perfectly consistent with the idea that single individual differences cannot have large effects on multiply deter- mined outcomes (see Ahadi & Diener, 1989 ). Finally, the RSE correlates positively with the Marlowe /C0Crowne Social Desirability Scale ( Crowne & Marlowe, 1960)(r5.22 based on data from over 7,000 college students; Trzesniewski et al., 2008 ). However, there is little evidence that controlling for social desirability or impression management substantially alters the criterion- related validity of measures of personality constructs (see Barrick & Mount, 1996 ;Li & Bagger, 2006 ) or the RSE in particular ( Moorman & Podsakoff, 1992 ). Location Rosenberg, M. (1989). Society and the adolescent self-image (Revised edition). Middletown, CT: Wesleyan University Press. Results and Comments The RSE is still the most widely used measure of self-esteem. It appears to generate reliable scores that have predictive validity. Nonetheless there are concerns about the RSE. For example, Byrne (1996) raised concerns about the dimensionality of the RSE and we noted this is an ongoing area of research. Moreover, relatively little research has been conducted to establish the nomological network of the positive and negative method factors136 6. MEASURES OF SELF-ESTEEM II. EMOTIONAL DISPOSITIONS
(cf.DiStefano & Motl, 2006 ;Quilty et al., 2006 ). These method factors are stable over time (e.g., see Gana et al., 2013; Marsh, 2010), but much more work on the importance of the RSE method factors is needed. Byrne (1996) raised a second concern about focusing on global self-esteem as opposed to multiple dimensions of self-esteem (cf.Marsh & Craven, 2006 ). This is a concern we address in more detail on the sections describing multidimen- sional self-esteem inventories. A final issue with the RSE concerns the limitations of subjective self-reports. Individuals may respond carelessly to survey items or they may distort their responses due to inadequate self- insight, or for reasons of self-deception or self-enhancement (see Boyle, 1994 , p. 650). This possibility motivates the search for implicit self-esteem measures designed to gain ‘a reliable window into what people think about themselves but cannot or will not report’ ( Buhrmester et al., 2011 , p. 377).

Variable Global self-worth or the overall attitude that one holds about oneself can be measured on a single-item scale ranging from negative to positive self-esteem ( Robins et al., 2001a ).137 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
Description The SISE was developed to serve as a proxy for the RSE in research contexts in which time constraints severely limit the number of items that can be administered (e.g., large-scale surveys, pre-screening packets, longitudinal studies, experience sampling studies). The SISE is a highly face valid measure that assesses an individual’s explicit knowledge about one’s global self-evaluation. The SISE provides a very brief, standardized measure that bypasses the need for individual researchers to abbreviate measures of global self-esteem. The SISE asks the par- ticipant to rate the statement ‘I have high self-esteem’ on a 5-point Likert-type scale, ranging from ‘not very true of me’ to ‘very true of me.’ Some researchers have used alternative item wording (‘My self-esteem is high’, ‘I see myself as someone who has high self-esteem’), scale anchors (‘strongly disagree’ and ‘strongly agree’), and response formats (7- and 9-point Likert-type rating scales), apparently with little/no appreciable effects on the psychometric properties of the measure (see discussion regarding number of response options in Chapter 1, this volume). Sample The SISE was initially developed and validated using data from four studies, a 4-year longitudinal study of college students, a cross-sectional study of college students, a community sample, and a sample of 4th to 8th grade children. In a separate study, Ackerman, Brecheen, Corker, Donnellan, and Witt (2013) investigated the test/C0retest reliability of the SISE in a sample of ( N5300) undergraduates (see below). Reliability Internal Consistency This is not relevant given the single item nature of the measure. Test/C0Retest Robins et al. (2001a) reported a test /C0retest coefficient of .75, using the Heise (1969) procedure for estimating test/C0retest reliability from the pattern of auto-correlations over six waves of data spanning four years of college. Vazire and Mehl (2007) reported a test /C0retest coefficient of .79, as cited in Vazire, Naumann, Rentfrow, & Gosling (2008, p. 1442) .Dollinger and Malmquist (2009) reported an 11-week test /C0retest coefficient of .55. Using unpublished data from approximately 300 college students at a Southwestern University followed over a 1-semester interval, Ackerman et al. (2013) reported a test /C0retest coefficient of .53 for the SISE (compared with .67 for the RSE). The test /C0retest reliability of the SISE compares favorably with that of other single-item mea- sures, according to a meta-analysis of single-item scales conducted by Postmes, Haslam, and Jans (2012) . Validity Convergent/Concurrent Robins et al. (2001a) reported positive correlations between the SISE and RSE of .75 in a sample of college stu- dents, .74 in a second sample of college students, and .80 in a community sample. The strong convergence between the SISE and the RSE measures held: (1) for males and females; (2) for different ethnic groups; (3) for both college students and community members; (4) for different occupational statuses; (5) across four years of college; and (6) for both a 5-point and 7-point rating scale. The SISE also exhibits moderate convergent validity during childhood, correlating .52 with the Harter (1985) Global Self-Worth (GSE) scale in a sample of 9- to 13-year olds; in the same sample, the correlation between parent reports of their children’s self-esteem using the SISE and the GSE was .74 ( Robins et al., 2001a ). Using data from over 1,200 first-year students at a Southwestern University, Ackerman et al. (2013) found a correlation of .68 between the SISE and RSE. Finally, the SISE was correlated .79 with a composite of the Tafarodi and Swann (2001) self-liking and self-competence scales/C0revised ( Gebauer, Riketta, Broemer, & Maio, 2008 ). Overall, these correlations are as high, if not higher, than those typically found between the various multi-item global self-esteem scales commonly reported in the literature. Robins et al. (2001a) found that higher scores on the SISE were as sociated with being male; more positive domain-specific self-evaluations; higher levels of Big Five Extraversion and Conscientiousness; lower levels of Big Five Neuroticism and shyness; higher levels of optimism; higher levels of psychological and physical health; and higher levels of peer-rated perfor mance in a group interaction task. The overall pattern of convergent correlations was nearly identical for the SISE and the RSE (correlation between the two138 6. MEASURES OF SELF-ESTEEM II. EMOTIONAL DISPOSITIONS
columns of correlations 5.98), supporting the validity of both scales. In terms of cross-method conver- gence correlations, child and parent reports of a ch ild’s self-esteem using the SISE were correlated .23 ( Robins et al., 2001a ); this level of agreement, although low, is not usual in studies of children (Meyer et al., 2001 ). Also, the SISE correlates positively (.30) with self-report measures of self-enhancement (Robins et al., 2001a ). Divergent/Discriminant Robins et al. (2001a) found that the SISE was not substantially co rrelated with Big Five Agreeableness and Openness to Experience ( r5.04 and r5.11, respectively); peer ratings of c ooperativeness, competitiveness, and creativity in a group interaction task (r5.08, .04, and .10, respectively) ; several measures of academic success (e.g., grades, test scores; rsr a n g ef r o m 2.10 to .05); or socioeconomic status ( r52 .02). In terms of socially desirable responding, the SISE is not correl ated with measures of impression management but is moderately correlated with self-report and cr iterion-based measures of self-enhancement ( Robins et al., 2001a ;r5.05 and r5.30, respectively). Jonason and Webster (2010) found that the SISE was not signifi- cantly or positively related to measures of psy chopathy, Machiavellianism, or narcissism ( r52 .09,2.09, and2.13, respectively), although Ames, Rose, and Anderson (2006) reported a correlation (.24) between the SISE and narcissism as assessed with a variant of t he Narcissistic Personality Inventory (NPI; Raskin & Terry, 1988 ). Such correlations are likely to be observed w hen measures of narcissism include attributes linked with social dominance and extraversion (see Brown & Zeigler-Hill, 2004 ). Also, in the Ackerman et al. (2013) study, the SISE did not correlate with the explo itative/entitlement dimension of the NPI ( r52 .02, N51,256). Construct Factor Analytic Factor analytic evidence is not relevant given the single item nature of the scale. Criterion/Predictive The SISE scores measured at the beginning of college were often predictive of a number of variables aggre- gated across the subsequent four years ( Robins et al., 2001a ). In addition, scores on the SISE were found to be predictive of cardiac vagal tone, suggesting better emotion regulation ( Schwerdtfeger & Scheel, 2012 ), and faster physiological (e.g., blood pressure) habituation to a stressful socially evaluative context such as public speaking (Elfering & Grebner, 2012 ).

Personality and Social Psychology Bulletin, 27 , 151/C0161. Results and Comments The SISE is the briefest measure of global self-esteem available. Despite its brevity, the pattern of convergent and discriminant correlates of the SISE closely mimic those of other more established measures of global self- esteem, such as the RSE. However, there are also several notes of caution to consider before using the SISE. First, it has lower test /C0retest reliability than multi-item measures of global self-esteem. This is likely due to the fact that random measurement errors are typically larger for items than scales (see discussion in Chapter 1, this vol- ume). Second, because it relies on the individual’s ability to know and acknowledge explicit feelings of global self-worth, it may not be suitable for children. Third, the SISE may be more susceptible to extremity and acquies- cence response styles because it has only one positively keyed item. Fourth, the SISE is a blatantly face valid mea- sure and shows some susceptibility to socially desirable responding, in particular to self-deceptive enhancement. However, this concern may be equally applicable to the RSE and other self-report measures of global self-esteem (see Robins et al., 2001a , Study 2). Fifth, although the SISE has been used in numerous studies conducted with North American samples, its reliability and validity in other cultures has yet to be systematically explored. In summary, the accumulated evidence suggests that the SISE provides a practical alternative to longer measures of global self-esteem.139 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
SINGLE-ITEM SELF-ESTEEM SCALE Instructions for participants: Please indicate the extent to which you agree with this statement. 1.I have high self-esteem Notes: Generally used with a 5-point scale ranging from 1 5not very true of me to 5 5very true of me. Source : Reproduced with permission. Self-Liking/Self-Competence Scale /C0Revised (SLSC-R) (Tafarodi & Swann, 2001 ). Variable Tafarodi and Swann (1995) argued that global self-esteem has two distinct components, one corresponding to a personal sense of worth (termed self-liking) and one corresponding to a sense of personal efficacy (termed self- competence). Self-liking is a general feeling towards the self, such as feeling positive affect when thinking of the self. Self-competence is the feeling of being capable and in control, and the belief that one will be successful in the future. Description The SLSC is a 16 -item self-report scale that includes items that measure self-liking and self-competence that are rated on a 5-point Likert-type response scale. The two 8-item subscales correlate from .47 to .59 ( Mar, DeYoung, Higgins, & Peterson, 2006; Meagher & Aidman, 2004; Tafarodi & Swann, 2001; Tafarodi, Wild, & Ho, 2010; Vandromme, Hermans, Spruyt, & Eelen, 2007; Wilkinson, 2010 ). Fifty percent of the items are reverse- worded (see discussion in Chapter 1). Tafarodi and Swann (1985) argue that these dimensions are related, but substantially distinct; thus, only studies that evaluated distinct self-liking and self-competence scales are reviewed here. Sample Three large samples, all university students ( Ns51,053, 835, and 844, respectively) were used in the construction/validation of the original SLSC measure ( Tafarodi & Swann, 1995 ). The revised SLSC scale was based on two further samples of university students ( Ns51,325 and N5298, respectively) ( Tafarodi & Swann, 2001 ). Reliability Internal Consistency Cronbach alpha coefficients were reported for self-liking (ranging from .70 to .98) and self-competence (ranging from .56 to .92) across the original and revised subscales ( Aidman, 1998 ; Bosson & Swann, 1991; Cicero & Kerns, 2011 ;Mar et al., 2006 ;Oakes et al., 2008 ;Riketta & Zieglet, 2006 ;Sasaki et al., 2010 ;Silvera et al., 2001;Song, Thompson, & Ferrer, 2009 ;Tafarodi & Swann, 1995,2001 ;Vandromme et al., 2007 ;Wilkinson, 2010). In addition, split-half reliability coefficients were high for both self-liking (.92) and self-competence (.75; Vandromme et al., 2007 ). Test/C0Retest Self-liking exhibited a test /C0retest reliability coefficient of .80 over a 3-week interval and self-competence exhib- ited a stability coefficient of .78 ( Tafarodi & Swann, 1995 ). Similar figures have been reported for the revised scales (.75 and .78, respectively, N5138; Tafarodi & Swann, 2001 ).140 6. MEASURES OF SELF-ESTEEM II. EMOTIONAL DISPOSITIONS
Validity Convergent/Concurrent Self-liking and self-competence both have strong positive correlations with the RSE. The correlations for the RSE and self-liking measured by the SLSC scale ranged from .74 to .88 and for the RSE and self-competence (from .53 to .88; Cicero & Kerns, 2011 ;Mar et al., 2006 ;Vandromme et al., 2007 ). Both self-liking ( β5.71 study 1, β5.62 study 2) and self-competence ( β5.28 study 1, β5.37 study 2) independently predicted scores on the RSE in regression analyses with both scales in the model ( Mar et al., 2006 ), and combined the two scales explain most of the variance in the RSE (R2ranging from .79 to .96; Mar et al., 2006 ;Tafarodi et al., 2010 ). Moderate corre- lations (ranging from .34 to .57) were found between reporters (mothers, fathers, and children) ( Tafarodi & Swann, 2001 ). Correlations with self-serving attributions were .22 for self-liking and .24 for self-competence (Cicero & Kerns, 2011 ). Self-liking scores correlated positively with reports of parental warmth ( r5.24 for men and r5.32 for women), and also correlated .16 with a measure of social desirability, while self-competence cor- related .23 with a measure of social desirability ( Tafarodi & Swann, 1995 ). Self-competence scores also correlated positively with self-ratings of abilities ( r5.30 for men and r5.48 for women) ( Tafarodi & Swann, 1995 ). Relations with self-deception were also independent and of similar magnitude (around .60 for self-liking and .50 for self-competence; Mar et al., 2006 ). Divergent/Discriminant Self-liking scores correlated around 2.30 with self-doubt while self-competence scores correlated 2.63 with self-doubt ( Greenway et al., 2003 ). Self-liking and self-competence correlated 2.63 and 2.57, respectively with neuroticism in one study ( Ramsdel, 2008 ) and2.68 and 2.41 in another ( Vandromme et al., 2007 ). Self-liking cor- related 2.45 with depression and self-competence 2.35 with depression ( Greenway et al., 2003 ).Tafarodi and Swann (1995) found that the self-liking and self-competence relations with depression were independent and approximately equal ( 2.30 for self-liking and 2.20 for self-competence), but others have found that the magni- tude of the relations varies by the type of depression measure used ( Silvera et al., 2001 ). Self-competence scores were not significantly correlated with reports of parental warmth ( r52 .11 for men and r5.01 for women) (Tafarodi & Swann, 1995 ). Likewise, self-liking scores were not correlated with self-ratings of ability ( r5.06 for men and r5.04 for women) ( Tafarodi & Swann, 1995 ). Construct Factor Analytic Competing factor models were tested using confirmatory factor analytic methods based on relatively large samples (e.g., N51,325 in Tafarodi & Swann, 2001 ). The model representing separate self-liking and self- competence factors fit the data best (compared with a single factor, positive and negative method factors, and hybrids of the two; Tafarodi & Swann, 1995,2001 ;Vandromme et al., 2007 ). However, Aidman (1998) conducted a principal component analysis (PCA) on a sample of Australian university students ( N5480) and found three components: the first comprised the positively worded items, the second captured the negatively worded self- liking items, and the third captured the positively worded self-competence items. Silvera et al. (2001) conducted a confirmatory factor analysis with 372 Norwegian college students providing support for the self-liking and self-competence factors in addition to negative and positive method factors. Criterion/Predictive Evidence of criterion/predictive validity is not currently available. Location Tafarodi, R.W., & Swann, W.B. Jr., (2001). Two-dimensional self-esteem: Theory and measurement. Personality and Individual Differences, 31 , 653/C0673. Results and Comments There is a potentially interesting conceptual distinction between self-liking and self-competence that could be a fruitful line for future theoretical and empirical work. However, the two subscales of the SLSC tend to be mod- erately correlated (e.g., r5.62;Zeigler-Hill, 2010 ). This level of association has perhaps motivated some to aggre- gate both scores into a single composite (see Buhrmester et al., 2011 ). It might be profitable in future work to develop scales that are more independent of each other. Likewise, additional work is needed to further identify the nomological networks of these two constructs as assessed by the SLSC measure.141 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS

Variable The family of SPP profiles each assesses global self-worth as well as multiple specific domains of self, relevant for individuals at different developmental periods ( Neemann & Harter, 2012 ). Description The original self-perception profile was developed for children aged 8 to 13 years and was briefly detailed in theBlascovich and Tomaka (1991) chapter. We expand on their treatment in this section to cover the entire family of Harter measures. There are different profiles for use with children, adolescents, college students, adults, and most recently, older adults. Each profile assesses multiple domains that are developmentally appropriate and the number of domains increases with age. The SPP presents two statements and asks the individual to choose the one that is most self-descriptive, and then rate it as ‘A Lot Like Me’ or ‘A Little Like Me.’ These responses are rated on a 4-point scale. The two-step, forced-choice format was originally designed to reduce socially- desirable responses but Marsh (1992a) has queried this claim. The scale for young children (preschool to third grade; boy and girl versions) is administered individually in pictorial format, eliminating the need for reading skills. However, no global subscale is available for young children because it was argued that children under eight years of age cannot communicate feelings of global self-worth ( Harter & Pike, 1984 ). The scales for other ages use the same format as the scale for young children, except words are used instead of pictures.142 6. MEASURES OF SELF-ESTEEM II. EMOTIONAL DISPOSITIONS
The pictorial scale for young children (aged 4 to 7 years) contains four subscales labeled: cognitive compe- tence, physical competence, peer acceptance, and maternal acceptance; however, analyses suggested only two dimensions based on samples of N5145 and N5104 children /C0competence and acceptance ( Harter & Pike, 1984 ). The child scale (aged 8 to 13 years) has six subscales labeled: scholastic, social, athletic, physical, behavioral, and global self-worth. The adolescent scale (aged 14 to 19 years) has nine subscales labeled: scholastic competence, social competence, athletic competence, physical appearance, job competence, romantic appeal, behavioral conduct, close friendship, and global self-worth. The college student scale (aged 17 to 23 years) has 13 subscales labeled: creativity, intellectual ability, scholastic competence, job competence, athletic competence, appearance, romantic relationships, social acceptance, close friends, parent relationships, sense of humor, moral- ity, and global self-worth. The adult scale (aged 20 to 60 years) has 12 subscales: intelligence, job competence, ath- letic competence, physical appearance, sociability, close friendship, intimate relationships, morality, sense of humor, nurturance, household management, adequacy as a provider, and global self-worth. The older adult scale (aged 60 years and older) has 14 subscales labeled: relationship with friends, family relationships, nurturance, adequacy as a provider, job competence, cognitive abilities, personal/household management, leisure activities, health status, physical appearance, morality, life satisfaction, reminiscence, and global self-worth. Sample The original samples were primarily drawn from Colorado in the USA and were mostly Caucasian. Sample sizes for the development of the Self-Perception Profile for Children (e.g., Harter, 2012a ) ranged from N5220 (Grade 5) to N5928 (Grade 6) with a total sample of 2,744 students in Grades 3 to 8. Sample sizes for the devel- opment of the Self-Perception Profile for Adolescents (e.g., Harter, 2012b ) ranged from N5165 (Grade 8) to N5361 (Grade 11) with a total sample of 1,099 students in Grades 8 to 11. The Self-Perception Profile for College Students ( Neemann & Harter, 2012 ) was developed using data from 300 college students. The Self- Perception Profile for Adults ( Messer & Harter, 2012 ) was developed using data from 356 parents (88% women). Reliability Internal Consistency Harter reported Cronbach alpha coefficients ranging from .71 to .92 across all of the subscales and ages (Harter, 1985 ; 2012; Neemann & Harter, 2012 ).Rose, Hands, and Larkin (2012) reported alpha coefficients ranging from .68 to .87 for the adolescent scale, consistent with several other studies conducted in different counties (seeRose et al., 2012 ). Alpha coefficients ranged from .70 to .89 for the adult scales ( Donnellan et al., 2007 ). Test/C0Retest Harter (1984) reported stability coefficients for eight samples for the child scale. These ranged from .70 to .87 for three months and .69 to .80 for nine months. A meta-analysis found a long-term stability coefficient of .43 (average time interval three years) for the global self-worth scale ( Trzesniewski et al., 2003 ).Donnellan et al. (2007) reported four-year stability correlations ranging from .38 to .77 for the adult scales. Validity Convergent/Concurrent The adult global subscale correlated .74 with the RSE Scale ( Donnellan et al., 2007 ) and the college student global scale correlated .75 with the RSE (Ferrier et al., 2008). The child subscales from the SPP correlated as expected with Marsh’s Self-Description Questionnaire (SDQ-I) using data from 508 students ( Marsh & Gouvernet, 1989 ). The physical scales from both inventories were correlated at .67, the social scale from the Harter inventory was correlated .74 with the peer scale for the SDQ-I, the cognitive scale from the Harter inven- tory was correlated .60 with the total academic scales, and the general scales from both were correlated at .57 (Marsh & Gouvernet, 1989 ). The child scales correlated positively with teacher reports of scholastic competence ( r5.35, .43, and .60 for students in Grades 2, 3, and 4, respectively; Boivin, Vitaro, & Gagnon, 1992 ), teacher reports of peer acceptance (r5.19, .28, and .33 for students in Grades 2, 3, and 4, respectively; Boivin et al., 1992 ) and teacher reports of peer status ( r5.27, .32, and .38 for students in Grades 2, 3, and 4, respectively; Boivin et al., 1992 ). In a sample of 107 Mexican-American school children, the scholastic scale was correlated with a positive school attitude (r5.58) and the physical ( r5.41), behavioral ( r5.64), and global scales ( r5.51) ( Hess & Petersen, 1996 ).143 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
Divergent/Discriminant Self-perception scores for the physical appearance scale did not correlate with teacher reports ( rs range from .08 to .12; Boivin et al., 1992 ). The adolescent version was unrelated or weakly related to social desirability with correlations ranging from .02 (for close friends) to .29 (for physical appearance), similar for the original forced- choice and alternative Likert-type format ( Wichstrom, 1995 ). The global Harter scales for children correlated negatively both with internalizing problems ( r52 .22) and externalizing problems ( r52 .30) as well as with measures of anxiety and depression ( r52 .56 and 2.67, respectively) in samples of Dutch children (Muris, Meesters, & Fijen, 2003 ). Construct Factor Analytic Several studies have evaluated the factor structure of the Harter measures, although these studies have tended to omit the global items and it is not clear whether the results would be different if the global items were included in the analyses. Some studies have replicated the intended factor structure ( Harter, 1985 ;2 0 1 2 ; Neemann & Harter, 2012) and using diverse samples ( Boivin et al., 1992; Ferrier & Martens, 2008; Granleese & Joseph, 1993; Miller, 2000; Muris et al., 2003; Rose et al., 2012; Van Dongen-Melman, Koot, & Verhulst, 1993; Worth et al., 1996 ), but others have been unable to replicate this factor structure or have only partially replicated it ( Egberink & Meijer, 2011; Eiser, Eiser, & Havermans, 1995; Rose et al., 2012; Thomson & Zand, 2002; Wichstrom, 1995 ). Criterion/Predictive Several studies have shown that the self-perception profile subscales predict hypothesized outcomes over time. For example, using the child scale, lower scores on the physical appearance scale predicted later depression (β52 .12;Kim-Spoom, Ollendick, & Seligman, 2012 ) and lower scores on the social competence scale predicted later internalizing and externalizing behaviors ( β52 .19 and β52 .18, respectively; Bornstein, Hahn, & Haynes, 2010 ). Lower scores on the physical appearance scale but not on the social competence scale, predicted later bulimic symptoms, controlling for prior symptom levels ( β52 .16 and β52 .02, respectively; Holm- Denoma & Hankin, 2010 ). Scores on the scholastic competence scale predicted later school engagement ( β5.18 Chen, Hughes, Liew, & Kwok, 2010 ). Similar predictive validity findings have been found using the adolescent scale: lower scores on the global self-worth predicted later disordered eating ( β52 .11 to 2.21; Kansi, Wichstrom, & Bergman, 2005 ;β52 .20 to 2.31;Salafia, Gondoli, Corning, Bucchianeri, & Godinez, 2009 ), declines in depressive symptoms ( β52 .30; Burwell & Shirk, 2006 ), and higher social acceptance scores predicted later peer-reported companionship, lower hostility, and lower withdrawal ( β5.19, β52 .31, and β52 .23, respectively; McElhaney, Antonishak, & Allen, 2008 ).

Scales and manuals can be downloaded from: http://portfolio.du.edu/SusanHarter (Retrieved January 1, 2014). Results and Comments The SPP measures have several benefits. Foremost, there are scales available for different age groups so these instruments permit a developmentally sensitive approach to assessing self-evaluations across the life span. Moreover, the scales appear to have predictive validity for important outcomes. However, there are also several notes of caution to consider before deciding to use the SPP. First, some participants do not understand the forced-choice format. In some of our own data, we found roughly 20% of children completed the scale incor- rectly, when administered in a group setting, making their data unusable (cf. Eiser et al., 1995 ). Harter has since updated her manuals providing detailed instructions for administering the scales to reduce this potential loss of data. Also, the forced-choice format may not be necessary. Wichstrom (1995) tested the forced-choice format and a standard Likert-type format and found the latter resulted in the same factorial structure, higher reliabilities,144 6. MEASURES OF SELF-ESTEEM II. EMOTIONAL DISPOSITIONS
and better convergent validity. Moreover, the Likert-type version showed just as low correlations with social desirability as did the original scale. Second, although the SPP scales form a life-span measure, the domains differ by age and there is some vari- ability in the item wording for the domains that do cut across age groups. Thus, for many analyses, age differ- ences will be somewhat confounded by differences in item content. Third, global self-esteem is not included until age 8 years because Harter (e.g., Harter & Pike, 1984 ) posited that children younger than 8 years are not able to make global evaluations about the self. However, Marsh et al. (1991) questioned Harter’s claim, and presented evidence of a well-defined global self-worth factor that was distinct from domain-specific factors in a sample of 6 to 8-year-olds (cf. Marsh, Ellis, & Craven, 2002 ). In addition, Verschueren, Buyck, and Marcoen (2001) assessed global self-esteem in 5-year-olds through a puppet interview and found good correspondence with self-reported global self-esteem at age 8 years. Thus, the omission of a global scale on the Harter measure for the youngest chil- dren may be a limitation. Fourth, more evidence is needed to support the number and type of domains for each age group. For example, Marsh (1992a) has made a convincing case for the value of assessing self-competence in the separate domains of mathematics and reading/verbal a bilities. The Harter scales do not separately assess these domains and this might be a concern, especially give n purported gender differences of self-perceptions in these domains. Conversely, there might be too many domains on some SPP versions. These domains add length without necessarily providing psychologic ally important information. In short, more work is needed to establish the validity and necessity of all t he domains assessed by the various profiles developed by Harter. In sum, there are a number of positive features of the Harter SPP measures ( Byrne, 1996 ). The global self- esteem scale converges strongly with the RSE and the re is little evidence (as yet) that one global scale is superior to the other. Our reservations are mostl y with respect to the response format of the items and t h en e e df o rm o r ee v i d e n c ef o rt h ev a l i d i t yf o re a c ho f the subscales. The bottom line is that if researchers wish to use a multidimensional measure of the self-c oncept, the decision will likely boil down to a choice between the Harter family of measures or the Self-Des cription Questionnaires (SDQ), discussed next. ADMINISTRATION INSTRUCTIONS FOR THE HARTER SELF-PERCEPTION PROFILE FOR CHILDREN Instructions to the child We have some sentences here and, as you can see from the top of your sheet where it says “What I am like”, we are interested in what each of you is like, what kind of a person you are like. This is a survey, nota test. There are no right or wrong answers. Since kids are very different from one another, each of you will be putting down something different. First, let me explain how these questions work. There is a sample question at the top, marked (a). I’ll read it out loud and you follow along with me. ( Examiner reads the sample question .) This question talks about two kinds of kids, and we want to know which kinds are most likeyou. (1)So, what I want you to decide first is whether you are more like the kids on the left side who would rather play outdoors, or whether you are more like the kids on the right side who wouldrather watch T.V. Don’t mark anything yet, but first decide which kinds of kids are most like you , and go to that side of the sentence. (2)Now the second thing I want you to think about, now that you have decided which kinds of kids are most like you, is to decide whether that is only sort of true for you,o rreally true for you . If it’s only sort of true, the put an X in the box under Sort of True for me; if it’s really true for you, then put an X in that box, under Really True for me. (3)For each sentence, you only check onebox. Sometimes it will be on one side of the page, another time it will be on the other side of the page, but you can only check one box for each sentence.

Furthermore, Susan Harter requests that all items from each domain scale are administered. Do not shorten the domain scales without explicit permission. However, researchers do not need to administer all scales depending on their research needs.146 6. MEASURES OF SELF-ESTEEM II. EMOTIONAL DISPOSITIONS
Self-Description Questionnaire (SDQ-1; SDQ-II; SDQ-III) (Marsh, 1992a,b,c ). Variable The basic underlying measurement philosophy of the SDQ scales is to assess aspects of the self-concept in domains that are developmentally relevant (such as academic domains and peer relationships). Individuals might feel positively about their level of fitness but not like their academic abilities so obtaining scores in different domains can provide a more detailed profile of an individual’s self-concept. Description Marsh and his colleagues have created a family of measures of the domains of the self-concept (see Byrne, 1996) based on theoretical considerations discussed extensively in Marsh (1990a) and Marsh and Craven (2006) . The various SDQ measures have developmentally appropriate scales for assessing different domains of the self- concept relevant for individuals of different ages. Each SDQ inventory has a global scale modeled on the RSE so that researchers can evaluate how strongly each domain is related to global self-esteem, the construct that is pos- ited to sit at the highest level of the self-concept hierarchy (see Marsh & Craven, 2006 ). SDQ-I ( Marsh, 1992a ) is a 76-item measure designed to assess aspects of the self-concept relevant for pre- adolescent children aged 8 to 12 years. A preliminary evaluation of the SDQ-I was presented in Blascovich and Tomaka (1991, pp. 144 /C0147). Items are answered on a 5-point scale ranging from ‘False’ to ‘True’ with a midpoint labeled ‘Sometimes false/Sometimes true’. Although originally designed for those in middle to late childhood, the items may be used with children as young as second grade. There is a version for even younger children (Kindergarten: aged 5 to 7 years) using a one-on-one interview format ( Marsh et al., 1991 ). The SDQ-I includes seven scales designed to measure broad domains of the self-concept relevant for preadolescents, four from the non-academic realm (labeled: Physical Abilities, Physical Appearance, Peer Relations, and Parent Relations) and three from the academic realm (labeled: Reading, Mathematics, and General School Subjects). Many of the items on the SDQ-I are similar to items on the SDQ-II and SDQ-III. The SDQ-II ( Marsh, 1992b ) is a 102-item measure designed to assess aspects of the self-concept relevant for adolescents roughly between the ages of 12 and 18 years (Middle School and High School). Items are rated on a 6-point scale ranging from ‘False’ to ‘True’. There is a general self-esteem scale and 10 domain scales - seven non-academic (labeled: Physical Abilities, Physical Appearance, Same-Sex Peer Relations, Opposite-Sex Peer Relations, Parent Relations, Emotional Stability, and Honesty) and three academic (labeled: Verbal, Mathematics, and General Academics). The SDQ-III ( Marsh, 1992c ) is a 136-item measure designed to assess aspects of the self-concept relevant for late adolescents and college students. The heavy focus on aspects of academic self-concept means that many scales will be less relevant for adults who are not at school. Byrne (1996) noted that certain domains relevant to older adults (e.g., domains of work and parenthood) are not well-represented in the SDQ-III. Items are rated on an 8-point scale ranging from ‘Definitely False’ to ‘Definitely True’. There is a general self-esteem scale and 12 domain scales /C0eight non-academic (labeled: Physical Abilities, Physical Appearance, Same-Sex Peer Relations, Opposite-Sex Peer Relations, Parent Relations, Emotional Stability, Honesty, and Spiritual Values/Religion) and four academic (labeled: Verbal, Mathematics, Problem Solving, and General Academics). Sample Data on the psychometric properties of the SDQ-I is based on 3,562 students from New South Wales, Australia. The global self-esteem scale was later developed for the SDQ-I using an 8-item general scale based on the RSE (see Marsh, Smith, & Barnes, 1985b, pp. 585 /C0586) and evaluated using data from 559 5th grade Australian school students. Initial information concerning the psychometric properties of SDQ-II were based on 901 Australian high school students as reported in Marsh et al. (1985a,b) , later refined using a large normative sample of 5,494 5th grade Australian school students ( Marsh, 1992b ). Normative data on the SDQ is based on 9,187 Australian high school students ( Marsh et al., 2005a,b ) and 17,544 students from the United States who completed 21 items from the SDQ as part of the National Educational Longitudinal Survey of 1988 ( Marsh, 1994 ). Normative data on the SDQ-III is available on an Australian sample ( N52,436; Marsh, 1992c ) and a Canadian sample ( N5991; Byrne, 1988 ).147 OVERVIEW OF THE MEASURES II. EMOTIONAL DISPOSITIONS
