Notes: Beta = change in z score per unit change in independent variables; SE = standard error; CI = confidence interval; χ 2 = critical ratio chi square; degrees of freedom for chi-square test = 3; CFI = comparative fit index; TLI =Tucker-Lewis index; RMSEA = root mean square error of approximation; CM = childhood maltreatment; Depression = major depressive disorder; PTSD = post-traumatic stress disorder; GAD = generalized anxiety disorder; ASPD = antisocial personal disorder. All psychiatric symptoms represent the number of lifetime symptoms. Substance use symptoms refer to the sum of the number of lifetime alcohol and drug symptoms from the DIS-III-R. All analyses controlled for age, sex, race and IQ score.
