Significant at the .05 level, two-sided test

Empty cells indicate the disorder specified in the row was not included in the model.

Bivariate models (each disorder in a separate discrete time survival model) include the following controls: age, age-squared, age cohorts, sex, and person-year.

Multivariate additive model (all disorders together in a discrete time survival model) includes the following covariates: age, age-squared, age cohorts, sex, and person-year.

Multivariate interactive model (all disorders together in a discrete time survival model controlling for number of disorders as interactions) includes the following covariates: age, age-squared, age cohorts, sex, and person-year.

Impulse-control disorders assessed in ages 18-44. In multivariate models, impulse-control disorders coded to 0 or “no” for Part II cases older than 44.

The group effect Chi square tests the set of coefficients for type of disorder for significance, while the individual Chi squares only test presence versus absence of each DSM-IV/CIDI disorder.
