Note. Analyses are restricted to the subsample of respondents with any lifetime mental disorder or any lifetime suicidal thoughts or behaviors (47.5% of the full sample). aOR: adjusted odds ratio; cat.: categorical; CI: confidence interval; con.: continuous; SE: standard error.
Respondents with age of last treatment lower than the minimum age of onset across the six mental disorders and suicidal outcomes under study are coded as not having received treatment.
Bivariate models adjust for the predicted probabilities calculated using the coefficients of the clinical predictors in the final model shown in Table 2 (last column).
Multivariate models adjust for the predicted probabilities calculated using the coefficients of the clinical predictors in the final model shown in Table 2 (last column) and for the predictors shown in the rows.
F‐test to evaluate joint significance of categorical predictor levels. ddf: denominator degrees of freedom; Ndf: numerator degrees of freedom.
