Note: Beta = standardized regression coefficient. Statistically significant main effects and interactions (p<0.05) are shown in bold.

Adjusted for any mental health treatment, race, marital status, employment status, education, income, enlistment status, combat veteran status, number of lifetime traumas, cognitive functioning, and physical health difficulties. Final unadjusted main effects model: F(4,715)=85.43, p<0.001; Final unadjusted model with interaction effects: Final adjusted model with main effects: F(15,703)=92.54, p<0.001; Final adjusted model with interaction effects: F(18,700)=83.28, p<0.001).
