  • Bivariate analysis of the association between each independent variable and the outcome. Multivariate analyses performed in three steps: the first model (work) includes all work characteristics with a p value<0.2 in bivariate analysis; in the second model (work and life), the same work related variables were included together with the non-work variables which showed a p value <0.2 in bivariate analysis. In the final model (work, life and symptoms at baseline) symptoms of mental illness at baseline were added to the previous model. Odds ratios with 95% CIs are used as the measure of association.
