Background Characteristics. Collected at baseline only, participant background characteristics will include sex, age, ethnicity, educational attainment, co-morbid medical conditions, military era served, branch of the military, marital status, residential status, current work status (employed/unemployed), work history (i.e., weeks worked during the six months preceding the study; number of jobs held within six months preceding the study; longest consecutive period in competitive employment in the past), entitlements received, and legal history (i.e., number of felony convictions). The investigators will collect this data through a combination of SE records, patient medical records (i.e., CPRS), and participant self-report.
