Abstract:
Objective criteria for predicting dysphoric mood states in college students from measures of stress and cognitive and personality variables were developed and cross-validated. Contrary to Beck's diathesis-stress model of depression, although dysfunctional attitudes, together with the number and impact of life events, self-esteem problems, and level of traditional feminine personality characteristics, predicted concurrent levels of depressive symptoms, initial level of depression was the best predictor of future depression. Cross-validation of the criteria resulted in accuracy rates of 86 to 87%. Implications of these results and some secondary findings were discussed.
