Friendship Scale (FS)The Friendship Scale (FS) is a 6-item self-report measurethat assesses perceived social isolation during the past fourweeks (Hawthorne, 2006). Respondents are instructed toplace an “X” on the line if they agree with the statementduring the specified time period.

Sensitivity to Blood, Injury, and Mutilation (SBIM)The Sensitivity to Blood, Injury, and Mutilation is a 5-item
self-report measure that assesses fear associated withgruesome or dangerous tasks or events where bodily injury
or mutilation are possible (Naifeh, Ursano, Benfer, et al.,2015). Derived from the 30-item Mutilation Questionnaire(MQ), the SBIM was originally developed as a 10-item scalethat predicted posttraumatic stress symptoms in special
operations soldiers. The scale was further refined into a5-item measure, and expanded to a 5-point Likert scale.
MoraleJob Morale
Job Morale is evaluated with a 4-item self-report measurethat assesses personal morale, motivation, energy, and driveat the present time (Britt & Dawson, 2005). Respondents
rate each item on a 5-point scale ranging from 1 = Very
Low to 5 = Very High.
Performance
Brief Resilience Scale (BRS)
The Brief Resilience Scale (BRS) is a 6-item self-reportmeasure that assesses the ability to bounce back or recoverfrom stress in one’s lifetime (Smith, Dalenm, Wiggins,Tooley, Christopher, & Bernard, 2008). Respondents rateeach item on a 5-point scale ranging from 1 = StronglyDisagree to 5 = Strongly Agree.
Dispositional Resilience Scale (DRS)The Dispositional Resilience Scale (DRS) is a 15-item selfreport measure that assesses three major components ofhardiness: commitment, control, and challenge (Bartone,Ursano, Wright, & Ingraham, 1989). Originally a 45-version
questionnaire, the DRS was shortened to a 15-item version
in subsequent studies. Respondents rate each item on afour-point Likert scale from 0 = Not at all True to 3 =Completely True.
Note: Use of this measure requires a license agreement.
Presenteeism
Presenteeism is a 5-item self-report measure that assesses
health-related reduced work performance (Stewart, Ricci,Chee, Hahn, & Morganstein, 2003). Respondents indicate
the amount of time during the specified time frame theylost concentration, repeated a job, worked more slowly thanusual, felt fatigued at work, and did nothing at work ondays when they were at work not feeling well. Responses
were rated on a 5-point Likert scale ranging from 1 = Noneof the Time to 5 = All of the Time.
World Health Organization Disability AssessmentSchedule (WHODAS-12)
The World Health Organization Disability Assessment
Schedule is a 12-item self-report measure that assesses theextent of disability. Questions are rated on a scale from
1 = None to 5 = Extreme/Cannot do (Weeks, Garber, &Zamorski, 2016).

Sleep
Daily Diary Study-Four Sleep Items
The Daily Diary Study’s four sleep items is a self-reportmeasure that assesses quality and quantity of sleep, andwhether sleep medication was used on the prior night.
Three of the items (sleep quality, number of hours ofactual sleep, and medication use) were adapted from thePittsburgh Sleep Quality Index (PSQI) and the last wasdeveloped for use in the Daily Diary Study at the Centerfor the Study of Traumatic Stress (Buysse, Reynolds, Monk,Berman, & Kupfer, 1989). The items are designed for use ona daily basis and response choices vary with each item.
Unit Cohesion
Unit Cohesion & Leadership
Unit Cohesion & Leadership is a 6-item self-reportmeasure that assesses unit cohesion, specifically horizontalcohesion, unit leadership, and unit functioning at thepresent time. Respondents are asked to think of theirunit at present and respond to items on a 5-point scaleranging from 1 = Strongly Disagree to 5 = Strongly Agree.
Unit cohesion is assessed with three items developed byPodsakoff and Mackenzie (1994) and modified for military
relevance by Castro and Adler (1998). Unit leadership isassessed using the three-item General Leadership Quality
Scale developed by Vaitkus (1994).
Well-Being
General Health Questionnaire (GHQ-12)
The General Health Questionnaire is a 12-item self-reportmeasure designed to determine whether an individual is at
risk of developing a psychiatric disorder (Goldberg, 1972).
The GHQ-12 is a shortened version of the original 60-item
instrument. The questionnaire focuses on breaks in normal
functioning rather than on life-long traits to assess wellbeing; therefore, it only covers disorders associated withdistress (Goldberg & Williams, 1988). Items are rated on a
4-point scale (0 = Not at all to 3 = A lot more than usual).

A wide range of psychiatric disorders and clinicalsymptoms can be assessed in special operators.
The Army Study to Assess Risk and Resilience inServicemembers (Army STARRS) developed a broad
variety of assessment instruments which have beenused around the world for survey research. For
