Significant at the .05 level, two-sided test.
Results are based on multivariate discrete-time survival models with person-year the unit of analysis, a logistic link function, and person-year defined as a separate dummy predictor variables for each year of life. Both models control for the socio-demographic variables in Table 2. Lifetime predictor disorders are coded as present only if their AOO is less than or equal to the age when the respondent made his or her first suicide attempt.
The bivariate model includes only one mental disorder in each equation, whereas the multivariate model includes all 15 mental disorders in the same equation. The addition of the 15 disorders to the predictor set in the multivariate model improves on the socio-demographic model in Table 2 (Akaike Information Criterion [AIC] = 2862.4 for the socio-demographic model and 2354.8 for the model that added the 15 mental disorders; the model with the lower AIC being the preferred model).
