Genetic mediation of longitudinal associations between family environment and childhood behavior problems
Authors: Braungart-Rieker Julia , Rende Richard D. , Plomin Robert , DeFries J. C. , Fulker David W.
Published: March 2009

Previous studies have reported significant associations between measures of the family environment and behavior problems in children. However, because children in these studies were genetically related to their parents, such links may not be caused solely by environmental influences. The goal of this study was to investigate genetic influence on associations between family environment and problem behavior using an adoption design. Participants in the study included 179 adopted and 176 nonadopted children, as well as their parents and teachers, in the Colorado Adoption Project (CAP; Plomin, DeFries, & Fulker, 1988). Mothers and fathers each completed the Family Environment Scale (FES) when their child was 1, 3, and 5 years of age; the child's problem behavior at age 7 was rated by both mothers and teachers using the Child Behavior Checklist (CBCL). Patterns of correlations for nonadopted versus adopted boys indicated that associations between aspects of the family's relationship (conflict, cohesion, expressiveness) and behavior problems in home and school were mediated genetically. For girls, however, these links appeared to be influenced by direct shared environmental effects.
Attachment in the context of high-risk conditions
Authors: Radke-Yarrow Marian , McCann Kathleen , DeMulder Elizabeth , Belmont Barbara , Martinez Pedro , Richardson Dorothy T.
Published: March 2009

The role of attachment in interaction with other relationships and conditions was investigated in relation to children's later psychosocial development (at ages 6 and 9). Thirty-nine unipolar depressed mothers, 24 bipolar mothers, and 32 normal control mothers and their children were studied. The network of conditions defining early experience included, in addition to attachment, maternal psychopathology, marital discord, other disordered relationships in the family, and recent losses of significant persons. Patterns of mother-child interaction were also examined. Assessments of children's problems were based on psychiatric evaluations of depressive affect, anxiety, and disruptive-oppositional behavior.

The findings support the conclusion that attachment enters into development in interaction with other relationships and conditions. Maternal psychopathology, in particular, in interaction with the attachment relationship, is linked to later developmental outcomes. The importance of considering mother-child interactional and dispositional characteristics is indicated. The early attachment relationship together with the ways in which the mother's depression is expressed with her child, and the child's style of coping with the mother's functioning establish patterns of behavior that influence the child's vulnerability to later problems. Multiple pathways of transmission of affective problems are discussed.
Attachment security and indiscriminately friendly behavior in children adopted from Romanian orphanages
Authors: Chisholm Kim , Carter Margaret C. , Ames Elinor W. , Morison Sara J.
Published: March 2009

Attachment security was assessed in children who had spent at least 8 months in a Romanian orphanage (RO) and two comparison groups of children: a Canadian-born, nonadopted comparison group (CB) and a comparison group adopted from Romania before the age of 4 months (RC). We also assessed differences in displays of indiscriminately friendly behavior between the two adopted groups of children. Attachment security was assessed using parent report on a questionnaire comprised of the 23 items with the highest and lowest loadings on the Waters and Deane (1985) attachment Q-sort. Indiscriminately friendly behavior was assessed using parents' responses to five questions about their children's behavior with new adults. Children's attachment security scores were also compared to parents' scores on the parent attachment subscale of the Parenting Stress Index (Abidin, 1990). RO children scored significantly lower on security of attachment than did either the RC or CB children. RC and CB children did not differ on attachment security. Based on their parents' reports, RO children displayed significantly more indiscriminately friendly behaviors than did RC children, but such behaviors were not correlated with security of attachment. Children's attachment security scores were related to their parents attachment scores only in the RO group. It is suggested that RO children's experience of extreme neglect contributed to their low attachment-security scores, and that indiscriminate friendliness may be an important behavior to consider in the study of attachment in institutionalized children.
Relational aggression: The role of intent attributions, feelings of distress, and provocation type
Authors: Crick Nicki R.
Published: March 2009

In recent research a relationally oriented form of aggression has been identified that, in contrast to overt aggression that harms others through physical means (e.g., hitting), harms others through damage to their peer relationships (e.g., angrily retaliating against a peer by excluding her from one's play group). The goal this research was to assess the role of intent attributions, feelings of distress, and provocation type (relational vs. instrumental) in children's relationally aggressive behavior. A total of 252 third- through sixth-grade children participated as subjects. A hypothetical provocation instrument was used to assess children's intent attributions and feelings of distress for ambiguous relational and instrumental provocation situations. Results showed that, as hypothesized, relationally aggressive children exhibited a hostile attributional bias and reported significantly higher levels of distress than did their nonaggressive peers for relational provocation situations. In addition, girls reported significantly higher levels of distress than did boys for relational provocation situations. Further, a comorbid group of relationally plus overtly aggressive children also exhibited a hostile attributional bias; however, their bias was evident for instrumental provocation situations only.
Covert visual attention in children with attention deficit hyperactivity disorder: Evidence for developmental immaturity?
Authors: Pearson Deborah A. , Yaffee Laura S. , Loveland Katherine A. , Norton Amy M.
Published: March 2009

Shifts in covert visual attention were compared in children with and without Attention Deficit Hyperactivity Disorder (ADHD) to determine if children with ADHD have developmental immaturities in covert attention, relative to their non-ADHD peers. Children were told to orient attention to a central fixation point and were then cued, by both central and peripheral cues, to direct their attention to either the left or right peripheral fields. Following variable time intervals, the target appeared and reaction times and errors were recorded. Although performance of all subjects showed faciliation when attention was directed by valid cues and inhibition when attention was directed by invalid cues, the performance of children with ADHD was far more disrupted when their attention was misled by invalid cues, especially at longer intervals. This inconsistency was reflected in significantly higher error rates in the ADHD group. They also showed a pattern of attentional “waxing and waning” in performance over longer time intervals that has been previously found in auditory attention switching over time within trials in children with ADHD. Overall, results are inconsistent with developmentally immature covert attention skills in ADHD. Findings are discussed in terms of the concept of global “developmental immaturity” in the attention skills of children with ADHD.
Memory and representation in young children with Down syndrome: Exploring deferred imitation and object permanence
Authors: Rast Mechthild , Meltzoff Andrew N.
Published: March 2009

Deferred imitation and object permanence (OP) were tested in 48 young children with Down syndrome (DS), ranging from 20 to 43 months of age. Deferred imitation and high-level OP (invisible displacements) have long been held to be synchronous developments during sensory-motor “Stage 6” (18–24 months of age in unimpaired children). The results of the current study demonstrate deferred imitation in young children with DS, showing they can learn novel behaviors from observation and retain multiple models in memory. This is the first demonstration of deferred imitation in young children with DS. The average OP level passed in this sample was A-not-B, a task passed at 8–12 months of age in normally developing infants. Analyses showed that individual children who failed high-level OP (invisible displacements) could still perform deferred imitation. This indicates that deferred imitation and OP invisible displacements are not synchronous developments in children with DS. This asynchrony is compatible with new data from unimpaired children suggesting that deferred imitation and high-level OP entail separate and distinctive kinds of memory and representation
Intermodal perception of affect in persons with autism or Down syndrome

Published: March 2009

Persons with autism (n = 28) or Down syndrome (n = 30) took part in a study of the ability to detect intermodal correspondence between facial and vocal/linguistic information for affect. Participants viewed 24 split-screen images of an individual talking and displaying a different affect on each side of the display (happy, sad, angry, surprised, or neutral). The vocal track, matching one affect (i.e., one side of the split-screen) but not the other, was played from a central speaker. Subjects were asked to point to the side matching the vocal track. The vocal track was desynchronized with both sides, so that rhythmic synchrony was greatly reduced and subjects must use affect to make their choices. In the first control condition, rhythmic synchrony information was restored. In a second control condition, inanimate objects and their sounds were presented. In the experimental condition, when verbal mental age and IQ were taken into account, the autism group performed more poorly than did the Down syndrome group in detecting intermodal correspondence of face and voice. When rhythmic synchrony information was available, both groups' performances improved, with the Down syndrome group performing slightly better than the group with autism. There were no group differences in the condition using inanimate objects. Results suggest that persons with autism may have difficulty detecting intermodal correspondence of facial and vocal/linguistic affect.
Children classified as controlling at age six: Evidence of disorganized representational strategies and aggression at home and at school
Authors: Solomon Judith , George Carol , De Jong Annemieke
Published: March 2009

The purpose of this study was to determine whether children classified as controlling in attachment differ from children classified into the traditional Ainsworth attachment categories in their symbolic representations of attachment and level of behavior problems. Sixty-nine middle-class kindergarten children and their mothers participated in a laboratory separation and reunion. Children enacted doll-play stories about attachment-related themes. A four-group representation classification scheme was developed from the doll-play transcripts of 27 children. Mothers (n = 44) completed Achenbach's Child Behavior Checklist and teachers (n = 40) completed a 30-item inventory of classroom behavior. Results showed significant agreement between the representational system and Main and Cassidy's classification system (1988) for children's reunion behavior. The doll-play of controlling children was characterized by themes of catastrophe and helplessness or by complete inhibition of play and suggested disorganization of representational processes. Controlling children also were described by mothers and teachers as significantly more aggressive than other children. The results validate the distinction between the controlling and traditional classification groups and suggest that controlling children are at risk for behavioral maladaptation at home and at school.
Regulation of depressive affect and interpersonal behavior among children requiring residential or day treatment
Authors: Breen Mary P. , Weinberger Daniel A.
Published: March 2009

Depression is often associated with social withdrawal. However, especially among children from traumatic backgrounds, dysphoric affect may also be manifested by increased demands for social contact. The present research employed intensive observations, children's self-reports, and therapist and staff ratings to investigate associations between affect regulation and interpersonal behavior among 32 emotionally disturbed children (ages 7 to 12 years) in residential or day treatment. As predicted, children who reported dysphoric moods on the Children's Depression Inventory (Kovacs, 1980/81) were most socially engaged and presented themselves as relatively vulnerable and dependent on others. These children not only expressed more overt sadness but also exhibited higher rates of excited/hyperactive behavior. The subgroup of children who were most prone to deny even normative levels of negative affect were least interpersonally involved as well as least impulsive. The results highlight the importance of individual differences in coping with traumatic relationship histories and the need for further study of the interplay between affect and interpersonal behavior in childhood psychopathology.
Longitudinal patterns of physical aggression: Associations with adult social, psychiatric, and personality functioning and testosterone levels
Authors: Windle Rebecca C. , Windle Michael
Published: March 2009

A retrospective longitudinal research design was used to evaluate male adult outcomes associated with four patterns of physical aggression from childhood to adulthood—child-only aggression, child and adult continuity of aggression, adult-onset aggression, and a contrast group with low levels of aggression in childhood and adulthood. The continuity and adult-onset aggression groups had the highest levels of social maladjustment (e.g., marital instability), psychiatric disturbance (e.g., alcohol disorders, major depression), personality dysfunction (e.g., higher prevalence of elevated borderline and narcissistic personality disorder scores), and higher plasma testosterone levels. The child-only aggression group manifested more psychiatric and personality disturbance than the contrast group, but not nearly as much disturbance as the continuity and adult-onset groups. After controlling for age and socioeconomic status (SES) variables, race (White/Black) was typically not a significant predictor of outcome variables. Findings are discussed with regard to life course implications of the physical aggression patterns, and of the support provided for an adult-onset aggressive type.
Peer interactions of autistic children and adolescents
Authors: Lord Catherine , MaGill-Evans Joyce
Published: March 2009

Two observational studies of verbal, high-functioning children and adolescents with autism; nonautistic, behaviorally disordered youngsters of equivalent verbal skills and chronological age; and verbal age-matched normally developing students during integrated summer day camps are reported. In the first study, observations were made of spontaneous peer interaction and play over the course of 2 weeks of day camp. The eight autistic subjects were consistently more likely to not be interacting and less likely to be engaged in any purposeful activity than the 16 other children. During the 2 weeks, time interacting and purposeful activity increased overall. In the second study, the quality of spontaneous peer-directed initiations was observed during free time in similar day camps the following summer. The 11 autistic children and adolescents produced fewer initiations than did the 20 other children and were less likely to smile or coordinate several behaviors with eye contact during an initiation. Autistic subjects were consistently more likely not to receive a response to their initiation than the other groups, although there was no identifiable relationship between the quality of the initiation and the likelihood of it receiving a response.
Peer relationships in boys with attention-deficit hyperactivity disorder with and without comorbid aggression
Authors: Hinshaw Stephen P. , Melnick Sharon M.
Published: March 2009

Peer relationship difficulties and peer rejection are common in youngsters with attention-deficit hyperactivity disorder (ADHD), mandating focus on assessment issues, underlying reasons for peer approval and disapproval, links with comorbid aggression, and the mediating role of sociocognitive mechanisms as well as emotion regulation strategies. With previously unfamiliar ADHD and comparison boys who attended naturalistic summer research programs, we found the following: (a) parent and teacher estimates (but not self-reports) showed moderate correspondence with peer-nominated social preference; (b) ADHD boys were more likely than their comparison peers to accept other ADHD agemates; (c) aggression and noncompliance Predominated as self-reported reasons for rejecting agemates in both ADHD and comparison groups, with Perceived similarity the chief mediator of peer acceptance; (d) the high-aggressive subgroup of ADHD boys showed markedly worse peer sociometric status than did ADHD boys without aggression, for whom social isolation was also a predictor of peer reputation; and (e) self-reported social goals of a sensation-seeking nature and observed emotional reactivity characterized high-aggressive boys with ADHD and predicted end-of-program peer disapproval. We discuss implications for normal developmental processes and for intervention efforts.
Predicting the longitudinal course associated with aggressive-rejected, aggressive (nonrejected), and rejected (nonaggressive) status
Authors: Bierman Karen Linn , Wargo Julie B.
Published: March 2009

A 2-year follow-up was undertaken of boys identified in grade school as aggressive-rejected, aggressive (nonrejected), rejected (nonaggressiye) or nonproblematic comparison. When the social outcomes of boys in each group were compared, aggressive-rejected children exhibited more conduct problems and social rejection at Time 2 than boys in the other aggressive or rejected groups. Behavior observations, teacher ratings, peer ratings, and open-ended peer interviews collected at Time 1 were used to test three predictive models that might account for the greater developmental risk of aggress-rejected boys. Multiple regression analyses suggested that a broad array of conduct problems, low levels of positive interaction skills, and high levels of peer dislike and ostracism each made unique contributions 10 to the stability of social adjustment problems of boys in the sample. Within group analyses of change suggested that prediction models varied for boys in the three risk groups. The implications of findings are discussed for developmental models of social risk and for intervention design.
Models of internalizing outcomes of early rejection
Authors: Burks Virginia Salzer , Dodge Kenneth A. , Price Joseph M.
Published: March 2009

Viewing social rejection from same-age peers as a source of stress for children, the current study sought to determine the most appropriate model of the effects of temporary versus consistent experiences with rejection for both short-term and long-term internalizing problems. Adopting a cross-sectional longitudinal design, the sociometric status of children in the first year of the study (when the children were in the first, second, or third grades), and then again in the next school year (when children were in the second, third, or fourth grades) was assessed to determine which children were rejected by their peers. Internalizing outcome measures were administered in the third and sixth years of follow-up. Results indicated that, for boys, the Threshold Model best represented the stressful effects of rejection. That is, only boys who were exposed to rejection for 2 consecutive years demonstrated both short-term and long-term internalizing problems in subsequent years. For girls, however, there appeared to be few significant differences among those who never experienced rejection, who had only temporary experiences with rejection, and girls who were consistently exposed to rejection. Results are discussed in terms of the significance of a Threshold Model as well as possible explanations for these gender differences.
Childhood peer rejection and aggression as predictors of stable patterns of adolescent disorder
Authors: Coie John , Terry Robert , Lenox Kari , Lochman John , Hyman Clarine
Published: March 2009

The significance of childhood peer rejection and aggression as predictors of adolescent disorder was tested on 1147 children who were followed longitudinally from Grade 3 through Grade 10. Growth curve analyses of parent- and self-reported problems suggested that boys who were both aggressive and rejected in third grade had profiles of increasingly severe internalizing and externalizing problems across three assessment points in adolescence. Other groups showed either decreasing symptom patterns from Grade 6 to 10 or had consistently lower problem profiles. The longitudinal patterns were more complex for the girls. Childhood peer rejection was the only predictor of stable disorder as reported by parents, whereas self-reported externalizing problems were best predicted by childhood aggression.
The influence of deviant peers on the development of boys' disruptive and delinquent behavior: A temporal analysis
Authors: Keenan Kate , Loeber Rolf , Zhang Quanwu , Stouthamer-Loeber Magda , van Kammen Welmoet B.
Published: March 2009

The concurrent and predictive influence of deviant peers on boys' disruptive and delinquent behavior was examined in a community sample of fourth- and seventh-grade boys, who were followed-up over six data waves. Analyses were conducted separately for three different types of behavior problems: authority conflict, covert, and overt disruptive behavior. Consistent with the existing literature, concurrent relations between peers' and boys' disruptive behavior were expected to be significant. A more informative test, however, was whether exposure to deviant peers resulted in boys' subsequent initiation of disruptive behavior. Although peer influences were expected in the predictive analyses, the relations were hypothesized to differ by type of behavior. The potential moderating effects of hyperactivity and poor parenting practices were also examined to test the hypothesis that boys who are already at risk for behavior problems will be more susceptible to deviant peer influence. Results supported the significant concurrent and predictive relation between exposure to deviant peers and boys' engagement in disruptive and delinquent behavior. There were no significant moderating effects of attention-deficit hyperactivity disorder (ADHD) or parenting practices on peer influence.
The changing importance of romantic relationship involvement to competence from late childhood to late adolescence
Authors: Neemann Jennifer , Hubbard Jon , Masten Ann S.
Published: March 2009

Although developmental theorists such as Sullivan (1953) and Havighurst (1972) have suggested that the formation of romantic relationships in adolescence is an important developmental task, researchers of the adolescent “problem behavior syndrome” have documented that early sexual intercourse is related to problems with conduct, academics, and chemical use. In this study multiple measures of competence and romantic relationship involvement were obtained from a normative community sample of children and adolescents. These were used in path analyses to document the concurrent and longitudinal predictions of romantic involvement and competence to examine the concurrent and longitudinal linkages of romantic interest and involvement to four other domains of adaptive behavior. Results suggest that although success in romantic relationships has roots in general peer competence, there may be both deviant and prosocial pathways of initial romantic involvement. Early romantic involvement in late childhood and early to middle adolescence may have negative consequences for academic, job, and conduct domains of competence. Later in adolescence, romantic relationship involvement loses its negative significance, perhaps as it becomes a normative developmental task. Results highlight the need for developmental research on the origins and meaning of romantic relationships, one of the most neglected aspects of peer relationships.
The roles of social withdrawal, peer rejection, and victimization by peers in predicting loneliness and depressed mood in childhood
Authors: Boivin Michel , Hymel Shelley , Bukowski William M.
Published: March 2009

The purpose of this study was to evaluate the relative contributions of social withdrawal, peer rejection, and victimization by peers in predicting feelings of loneliness and depressed mood over time. According to the proposed model, the feelings of loneliness associated with social withdrawal are mediated by the negative peer experiences (negative peer status and peer victimization) to which withdrawn children are exposed. In predicting depressed mood over time, it was further hypothesized that self-reported loneliness ultimately mediates the subsequent depressed mood associated with withdrawal and negative peer experiences. The study was conducted across 2 consecutive years (Time 1 and Time 2), with children each year nominating peers for peer status, social withdrawal, and victimization measures, and completing self-report measures of loneliness and depressed mood. Fourth- and fifth-grade children participated at Time 1, and children that remained in the same school were again evaluated at Time 2 (N = 567). A series of regression analyses indicated that the postulated sequence of mediations adequately represented the pattern of longitudinal associations between the variables, as well as their pattern of change over time. The contribution of social withdrawal to the prediction of subsequent loneliness was accounted for by the expected pattern of mediations of negative peer experiences. Self-reported loneliness ultimately mediated the subsequent depressed mood associated with withdrawal and negative peer experiences.
Peer variables as predictors of later childhood adjustment

Published: March 2009

This study examined the relation between children's peer relationships and teacher-rated psychological adjustment. A number of shortcomings in the peer literature were addressed by: (a) employing carefully delineated peer variables (passive isolation, rejected isolation, aggressive-disruptive, peer preference, mutual friendship); (b) employing a data analytic strategy that permitted simultaneous examination of main effects of and interactions among peer variables; (c) using an outcome measure that is well-normed for children and widely used in studies of adjustment; and (d) controlling for outcome measures' autocorrelations across time points. For 236 school children in the third, fourth, and fifth grades, concurrent associations were examined between these peer variables and internalizing and externalizing problems. Longitudinal associations were examined over a period of 2 years. In so doing, we found that passive isolation was a risk factor for internalizing problems, and rejected isolation was marginally predictive of externalizing problems. Furthermore, we found complex moderating effects of mutual friendship, such that children who were not isolated may derive benefits from having a close mutual friend, but the results were not clear for children with poor peer-group relationships. Much additional research is needed to further clarify these findings.
Developmental patterns of childhood peer relations as predictors of externalizing behavior problems
Authors: Kupersmidt Janis B. , Burchinal Margaret , Patterson Charlotte J.
Published: March 2009

Developmental patterns of childhood peer relations were examined in the prediction of externalizing behavior problems in a 4-year multiple cohort longitudinal study. The participants consisted of 880 third- (M = 9.3 years) through seventh- (M = 13.4 years) grade students. Approximately half of the participants were female, one third were Black, and one third were from low-income homes. Developmental patterns of six indices of peer relations (including group acceptance, group rejection, having a reciprocated best friend, social support from best friend, conflict with best friend, and the aggressiveness of the best friend) were examined as predictors of aggression and delinquency using logistic regression analyses. Results suggest that both group and dyadic peer relations problems are risk factors for aggression and delinquency. Support was found for the cumulative risk model in the prediction of externalizing outcomes from multiple social risk factors that were additively associated with each negative outcome.
Impaired regulation of arousal in 3-month-old infants exposed prenatally to cocaine and other drugs

Published: March 2009

This study investigated relations between drug exposure, particularly cocaine, and infants' regulation of arousal in response to novelty. Sixty-three infants — 36 cocaine exposed and 27 non-cocaine exposed — participated at 3 months of age in a novel-repeat stimulus presentation procedure. Arousal was operationalized in terms of infant behavioral state, affective expressiveness, and attention to the stimulus. Infants were tested and infant behaviors were scored by experimenters blind to the drug exposure status of the infant. There were no differences between the two groups in baseline behavioral state or affective expression before the presentation of novel stimuli. Compared to the non-cocaine-exposed group, infants exposed prenatally to cocaine and other drugs were more likely to exhibit a crying state and to display negative affect on novel stimulus presentations. There were no group differences in the amount of looking toward the stimulus. Both groups showed less crying and negative affect when stimuli were presented a second time, but decrements were consistently greater for the cocaine-exposed group. These results obtained when group differences were controlled for sociodemographic and perinatal variables. Sources of differences in the regulation of arousal in cocaine-exposed and non-cocainc-exposed infants are discussed, and impairments in the regulation of arousal in cocaine-exposed infants are considered in a framework of predictive implications for children's social and cognitive development.
The role of frontal activation in the regulation and dysregulation of social behavior during the preschool years
Authors: Fox Nathan A. , Schmidt Louis A. , Calkins Susan D. , Rubin Kenneth H. , Coplan Robert J.
Published: March 2009

We examined whether the interaction of resting frontal electroencephalogram (EEG) asymmetry and social behavior during peer play was related to the occurrence of maladaptive behavior in preschoolers. Two independent cohorts of children were observed interacting in same-age and -gender play quartets at 4 years of age. Each child was also seen individually for a psychophysiology session during which time measures of EEG activity were recorded. We found that highly sociable children who exhibited greater relative right frontal EEG asymmetry were more likely to exhibit externalizing problems than sociable children who exhibited greater relative left frontal EEG asymmetry. We also found that shy children who exhibited greater relative right frontal EEG asymmetry were more likely to exhibit internalizing problems than shy children who exhibited left frontal EEG asymmetry. These findings suggest that the pattern of frontal EEG asymmetry in combination with social behavioral style is a significant predictor of maladaptive behavior problems during the preschool period.
Altered neuroendocrine activity in maltreated children related to symptoms of depression
Authors: Hart Jordan , Gunnar Megan , Cicchetti Dante
Published: March 2009

This study examined the effects of stressful environments on physiological and affective functioning among 131 maltreated school-aged children attending a summer day camp. Sixty-six nonmaltreated children also attending the camp served as a comparison group. Salivary Cortisol measures were obtained daily at 10:00 a.m. and at 4:00 p.m. Depression was measured using the Child Depression Inventory. Children with scores of 19 or higher were classified as depressed. Internalizing and externalizing behavior problems were determined from the Teacher Report Form of the Child Behavior Checklist. Children with t scores of 70 or higher were classified as having clinical levels of these problems. Maltreated children had slightly elevated afternoon Cortisol concentrations, but their morning concentrations did not differ significantly from those of nonmaltreated children. Neither clinical levels of depression, internalizing, or externalizing problems were predictive of the elevated afternoon values. Depression among maltreated children was, however, associated with altered activity of the hypothalamic-pituitary-adrenocortical (HPA) axis. Depressed maltreated children had lower morning Cortisol concentrations compared to nondepressed maltreated children and were more likely to show a rise rather than the expected decrease in Cortisol from morning to afternoon. These data replicated earlier findings. There was no evidence that depressed, nonmaltreated children exhibited this change in diurnal Cortisol activity.
A general quantitative theory of personality development: Fundamentals of a self-organizing psychobiological complex
Authors: Švrakić N. M. , Švrakić Dragan M. , Cloninger C. Robert
Published: March 2009

A general theory of personality and its development is described in terms of four quantitative dimensions of temperament and three quantitative dimensions of character. The four temperament dimensions (harm avoidance, novelty seeking, reward dependence, and persistence) are moderately heritable, moderately stable throughout life, and invariant despite sociocultural influences. The three character dimensions (self-directedness, cooperativeness, and self-transcendence) mature in a stepwise manner from early childhood throughout adulthood. Transitions between levels of maturity are nonlinear functions of temperament, specific genetic influences, social learning, and random life events. Personality development is quantitatively formulated in terms of nonlinear dynamics of a complex adaptive system. The psychosocial interpretation of personality as a fitness-optimizing process is described and illustrated in terms of available data about the development of different personality configurations. Several quantitative predictions of this theory of personality development are tested, including the sequence of emergence of the different character dimensions, individual differences in the development of stable temperament configurations, and the effects of sociocultural influences. The theoretical predictions agree with available empirical data and suggest many hypotheses for future developmental research, including etiological, dynamic, and therapeutic studies.
Developmental psychobiology of cyclic affective illness: Implications for early therapeutic intervention
Authors: Post Robert M. , Weiss Susan R. B. , Leverich Gabriel S. , George Mark S. , Frye Mark , Ketter Terence A.
Published: March 2009

The recurrent affective disorders are discussed from the perspective of accumulating inherited and experiential effects on gene expression. Stress and episodes of affective illness are viewed as leaving biochemical and microstructural residues in the central nervous system (CNS) in relation to their patterning, severity, and recurrence. Comorbid factors such as substance abuse and developmental disturbances may also interact with these illness-related variables. In addition to the primary pathological processes, secondary adaptive changes can also be induced, which, in concert with pharmacological interventions, may be sufficient to counter episode occurrences and illness progression. We postulate that the balance of primary pathological and secondary adaptive changes at multiple levels of CNS regulation accounts for recurrence and cyclicity in the affective disorders. The importance of early, effective, long-term interventions in the recurrent affective disorders and the therapeutic potential of several new treatment modalities including repeated transcranial magnetic stimulation (rTMS) are discussed.
Can we teach children with autism to understand emotions, belief, or pretence?
Authors: Hadwin Julie , Baron-Cohen Simon , Howlin Patricia , Hill Katie
Published: March 2009

Previous studies have revealed a “theory of mind” impairment in children with autism. The aim of this study was to assess whether it is possible to intervene by teaching children with autism to understand the mental states of emotion, belief, or pretence. Results showed that it is possible to teach children with autism to pass tasks that assess emotion and belief understanding. Introducing unfamiliar materials in structurally similar tasks did not adversely influence teaching effects, either immediately after teaching, or 2 months later. However, teaching effects did not generalize to tasks in domains where children received no teaching. In addition, no significant progress in spontaneous pretend play resulted from teaching. These results indicate that children may be passing tasks using rules rather than any genuine understanding of the concepts involved.
Childhood-onset versus adolescent-onset antisocial conduct problems in males: Natural history from ages 3 to 18 years
Authors: Moffitt Terrie E. , Caspi Avshalom , Dickson Nigel , Silva Phil , Stanton Warren
Published: March 2009

We report data that support the distinction between childhood-onset and adolescent-onset type conduct problems. Natural histories are described from a representative birth cohort of 457 males studied longitudinally from age 3 to 18 years. Childhood- and adolescent-onset cases differed on temperament as early as age 3 years, but almost half of childhood-onset cases did not become seriously delinquent. Type comparisons were consistent with our contention that males whose antisocial behavior follows a life-course-persistent path differ from males who follow an adolescence-limited path. As adolescents, the two types differed on convictions for violent crime, personality profiles, school leaving, and bonds to family. These differences can be attributed to developmental history because the two groups were well matched on measures of antisocial conduct at age 18 years: parent-reports, self-reports, and adjudication records. By age 18 years, many conduct-problem boys had encountered factors that could ensnare them in an antisocial future: substance dependence, unsafe sex, dangerous driving habits, delinquent friends, delinquent perceptions, and unemployment. Implications for theory, research design, prevention, and therapeutic treatment of conduct problems are highlighted.
Problem behavior as a precursor of male criminality
Authors: Hämäläinen Minna , Pulkkinen Lea
Published: March 2009

The participants (originally 196 boys and 173 girls) in an ongoing longitudinal study were examined using peer nomination and teacher rating at ages 8 and 14 years. Criminal records were collected at age 27 years. The results showed that (a) criminal offenses were best predicted if the accumulation of behavior problems over the school years was considered; (b) the risk for different types of offenses was highest for boys who exhibited escalating conduct problems and school failure over the school years; (c) norm-breaking behavior in early adolescence was strongly related to a propensity to later criminal offenses; (d) childhood aggressiveness did not predict arrests without the presence of other problems. When followed by norm-breaking in early adolescence, it predicted violent offenses, and when followed by poor school success, it predicted property offenses; (e) interestingly, low prosociality turned out to have a significant independent relationship to arrests; and (f) the distinction between an early-onset path and a late-onset path proved to be valid.
Troubled family interaction during toddlerhood
Authors: Belsky Jay , Woodworth Sharon , Crnic Keith

To examine the antecedents and consequences of troubled family interaction during the “terrible twos,” 64 of 69 families rearing firstborn sons who were observed in the child's second year of life were observed again in the child's third year. Cluster analysis of parent and child behavior scores was used once more to identify families whose parent-child interactions during parental efforts to control the child looked “troubled” at 27 and/or 33 months so that chronicity of troubled family interaction across the second and third year of life could be appraised. Nine predictor variables suggested by Belsky's model of the determinants of parenting, measured at the end of the first year of life, along with social class, were found to powerfully discriminate families that were troubled never or once from those who were troubled twice from those who were troubled three to four times across the four measurement occasions. Child externalizing problem behavior at 3 years of age was found to be almost monotonically related to chronicity of troubled family interaction, irrespective of whether problem behaviors were reported by mothers, fathers, or daycare providers.

We examined the role of a history of sexual abuse as a predictor of child maltreatment by adolescent mothers in a prospective study of 104 mother-child dyads. Mothers were interviewed about any experienced abuse, and the mother-child dyads were observed in a teaching interaction and in the Strange Situation when the children were 1 year old. Three and a half years later, the mothers were interviewed about their Child Protective Service (CPS) contacts since the birth of their children. The percentage of mothers reporting CPS contacts for their own children was 15.4%, 38.5%, and 83.3%, respectively, for those mothers with no history of sexual abuse, a history of a single incident or brief duration of sexual abuse, and those mothers with a history of chronic sexual abuse (median 24 months duration; test of increasing trend significant atp< .000009). Mothers who reported having been chronically sexually abused as children were significantly more likely to have CPS contacts for their own children, after controlling for history of physical abuse, quality of early teaching interactions, and infant attachment security (both of which also predicted CPS contacts), race, IQ, welfare status at 1 year postpartum, and history of foster care.

The association between attachment and behavior problems was examined for a nonclinical, diverse sociocconomic status (SES) French-Canadian sample of 77 children. Attachment classifications were assigned on the basis of reunion behavior with mother when the children were between 5 and 7 years of age. Teachers rated children's problem behavior using the Socioaffective Profile within 3 months of the attachment assessment (Time 2) and 2 years earlier (Time 1). Results indicated that children with a D classification were more likely than secures or other insecure groups (A or C) to be classified in the problem group at both ages. A majority (80%) of the D group showed problem behavior at some point during the 3–7 year period compared with a minority of A, B, or C children. However, only about 30% of controlling children (like other insecures) had stable problems. Analyses of subclinical scores showed that both controlling and avoidant groups were lower than secures in social competence at Time 1. At Time 2, A group children were lower in externalizing behavior, and C group children were higher. These results extend the association between the D classification and maladaptation previously found for clinical and high-risk samples to a nonclinical, mixed SES sample.
Psychosocial correlates of dyslexia across the life span

This series of four studies examined the psychosocial functioning of children, adolescents, and adults with developmental dyslexia. One sample of nonreferred dyslexic and nondyslexic men, and three different samples of dyslexic and normally achieving control children and adolescents were studied. The child samples included both clinic-referred and nonreferred populations, and sibling and nonsibling control designs. Variables assessed included depressive and ADHD symptomatology, self-concept and, in the adult sample, socioeconomic status and other life adjustment variables.

We found that, across three samples, children and adolescents report lower global self-worth and lower perceived competence in scholastic domains, more depressive symptomatology, and (both by self- and parent report) more ADHD symptomatology than normal achievers. In contrast, adult dyslexic men, while also perceiving themselves as less intelligent than their peers, reporting more generalized psychological distress, and showing less social mobility, were nonetheless comparable to their peers in terms of global self-worth, depressive symptomatology, and other indices of adult adjustment and satisfaction. Results are discussed in terms of a developmental “niche-finding” model, in which the shift into adult life may foster more constructive experiences and internal processes.
Early risk factors and pathways in the development of early disruptive behavior problems

This study examined risk factors from infancy associated with the development of preschool disruptive behavior problems across child, parent, and sociodemographic domains. Risk factors that consistently were associated with the prediction of disruptive behavior at age 5 years included disorganized attachment classification at 12 months, and maternal personality risk and child-rearing disagreements during the second year. In addition, infants with disorganized attachment status at 12 months whose mothers perceived them as difficult in the second year showed significantly higher aggressive problems at age 5 years than those with only one of the two risk factors present. When pathways leading to clinically elevated aggression at age 5 were explored, infant disorganized attachment status, maternal personality risk, and child-rearing disagreements demonstrated equivalent predictive validity as child aggression assessed at age 3 years.
