ORs (95% CIs) and Cohen d estimates are adjusted for age, gender, race/ethnicity, income, education, marital status, branch of service, combat status, and years in the military.
Lifetime psychopathology = major depression disorder, social phobia, posttraumatic stress disorder, or suicide attempt.
Lifetime substance use disorder = was categorized as lifetime alcohol use disorder or drug use disorder.
Spearman rho correlation (p) is provided because of non-normal [skewed, kurtotic] distribution.
