Abbreviations: OR, odds-ratio; CI, confidence interval; PTSD, post-traumatic stress disorder; ODD, oppositional-defiant disorder; ADHD, attention deficit/hyperactivity disorder.

P<.05, two-sided test.

Each column represents a separate multivariate model in survival framework, with all rows as predictors controlling for age, age^2, sex, cohorts, int categories. Outcome variable indicated in each column header. Multivariate models assessed in Part II sample; impulse disorders set to “No” in cases with age>44.

Group effect chisquare is for the multi-df tests to assess any difference between all the disorders, while the individual chi-squares only tests yes vs no for each disorder.

Group effect chisquare is for the multi-df tests to assess any difference between all the # of disorder dummies, while the individual chi-squares only tests yes vs no for each.

Denominator sample size of the models.
