Depression symptoms were measured using a modified, locally validated version of the 15-item Hopkins Symptoms Checklist (HSCL-25) depression subscale. Respondents reported symptom frequency in the last month (0 "None of the time" to 3 "Almost always"). An algorithm was applied to the HSCL-25 to determine eligibility on the basis of moderate to severe depression. The HSCL-25 was also used to measure the depression severity outcome: Scores on the depression scale were calculated as average symptom scores across the 17 items and therefore ranged from 0-3

Posttraumatic stress symptoms (PTSS) were measured using the 30-symptom items of the Harvard Trauma Questionnaire (HTQ). Response options were the same as the HSCL-25. An algorithm was applied to the HTQ to determine eligibility on the basis of moderate to severe PTSS. The HTQ was also used to measure the PTSS severity outcome: Scores for PTSS were calculated as average symptom scores across the 30 items. PTSS scores ranged from 0 (best possible outcome) to 3 (worst possible outcome).

Functional impairment was measured using locally-developed, gender-specific scales. The scales contained 16 and 23 tasks for men and women, respectively. Respondents reported current difficulty compared to others of same gender and similar age (from 0 "No difficulty" to 4 "Often cannot do"). Scores were calculated as average task scores across the 16- and 23-item scales and therefore ranged from 0-4

Anxiety symptoms were measured using the 10-item HSCL-25 anxiety subscale with local adaptations. Respondent instructions and response categories were the same as the HSCL-25 depression subscale. Scores were calculated as average symptom scores across the 11-item scale and therefore ranged from 0-4

The 12-item Aggression Questionnaire (AQ) was adapted for local use. Respondents rated frequency in general of aggressive behaviors from 0 "None of the time" to 4 "Almost all of the time." Scores were calculated as averages scores for each behavior across the 12-item scale and therefore ranged from 0-4

Alcohol use was measured using the Alcohol Use Disorders Identification Test (AUDIT). Respondents reported frequency and amount of alcohol consumed, referencing photographs of local alcohols (local beers, rice whiskeys, etc.). Total scores were calculated as sum totals across the 10-item scale. AUDIT total scores ranged from 0 (best possible outcome) to 40 (worst possible outcome).
