Abstract

Nineteen patients with an episode of major depressive disorder who did not recover within two years of prospective follow-up were compared with an equal number who recovered within a year of the initial evaluation and remained well through the two-year follow-up date. The groups were individually matched for age, sex, primary/secondary status, and prior duration of episode. The only psycho-social variable that predicted chronicity was increased neuroticism on self-report personality inventories administered during the index evaluation. Early loss, recent life events, and recent social supports were not predictive of outcome.
