Stressful life events interacting with cognitive/personality styles to predict late-onset major depression

The current work evaluated the interaction of life stressors with cognitive/personality styles in predicting late-onset depression in 42 elderly outpatients with DSM-IV unipolar Major Depression and 42 nondepressed controls. Control subjects were matched to cases on age, sex, race, and years of education. As suggested by Beck's cognitive theory of depression, a multivariate model indicated that specific stressful-event types interacted with specific cognitive/personality styles in strongly predicting depression onset, adjusting for the positive associations of medical illness and reduced physical functioning with depression.
