Prospective incidence of first onsets and recurrences of depression in individuals at high and low cognitive risk for depression.

Do negative cognitive styles provide similar vulnerability to first onsets versus recurrences of depressive disorders, and are these associations specific to depression? The authors followed for 2.5 years prospectively college freshmen (N = 347) with no initial psychiatric disorders at high-risk (HR) versus low-risk (LR) for depression on the basis of their cognitive styles. HR participants had odds of major, minor, and hopelessness depression that were 3.5-6.8 times greater than the odds for LR individuals. Negative cognitive styles were similarly predictive of first onsets and recurrences of major depression and hopelessness depression but predicted first onsets of minor depression more strongly than recurrences. The risk groups did not differ in incidence of anxiety disorders not comorbid with depression or other disorders, but HR participants were more likely to have an onset of anxiety comorbid with depression.
