Personality traits and recovery from major depressive disorder

Abstract

In this whole cohort of depressive patients, baseline high Self-Directedness predicted higher depression scores after 4 months of treatment. In the fluoxetine treatment group, subjects with high baseline Reward Dependence, Self-Directedness or Cooperativeness were likely more severely depressed at the 4 months follow-up. We suggest that associations between personality traits and remaining depressive symptoms after 4 months treatment with fluoxetine could be caused by the potential differences in the placebo effect.
