    Workplace factors and the transition to major depression in a representative sample of Alberta employees
    (2014-12-24) Bolo, Carmelle Angelie; Wang, JianLi
    Subthreshold depression is prevalent and increases risk of Major Depressive Disorder (MDD), though psychosocial workplace factors associated with the transition have not been explored. Using data from the Population-based Longitudinal Study on Work and Health, participants with no depression (n=2840) and subthreshold depression (n=305) were followed prospectively for two years. Subthreshold depression was measured with the Patient Health Questionnaire-9, while MDD was measured with the Composite International Diagnostic Interview-Auto 2.1. Using binomial regression modelling, those with high work to family conflict had an increased risk of 2-year transition to subthreshold depression (RRadj 1.47; 95% CI: 1.05-2.05; p=0.02) and 1-year transition to MDD (RRadj 2.88; 95% CI: 1.08-7.62; p=0.03) compared to those with low work to family conflict. Similar risk factors appear to exist for subthreshold depression and MDD. Future studies with larger sample sizes should consider multinomial transitions including outcomes of more severe depression, less severe depression, and no change.
