Five-year prospective neuroticism–stress effects on major depressive episodes: Primarily additive effects of the general neuroticism factor and stress.

Abstract

= 559) oversampled for high neuroticism and assessed for presence of MDEs annually for 5 years. Survival analyses provided relatively consistent support for the main effects of the broad vulnerability factor of the general neuroticism factor, acute stressors, and chronic stressors in the prediction of MDEs. In contrast, the majority of our analyses failed to support interactive neuroticism-stress accounts of MDE risk. Integrating our results with the extant literature reinforces the notion that both the general neuroticism factor and stress prospectively predict depressive disorders and highlight that their main effects are significantly larger than their interaction.
