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.

Models are all in survival framework and all control for age, age-squared, sex, cohorts, and int categories. Int categories have cut-off points of 1–5,6–10,11–15,....70–75 up to largest int available in dataset. Bivariate model assessed in Part I or II depending on the disorder. 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.
