Summary:

Cognitive theories of depression suggest that cognitive symptoms may play a role in the etiology of depression and thus may be found before as well as during depressive episodes. Using a prospective, longitudinal design, this study tested the hypothesis that cognitive symptoms temporally precede depression and evaluated potential causal roles that the symptoms may play. Depressive symptom levels in the year prior to depression diagnosis were compared for 63 study participants who became at least moderately depressed and 63 nondepressed controls. Results support a potential causal role for negative cognitions in depression from two perspectives. First, as expression of a stable vulnerability factor, negative cognitions may represent a diathesis for depression. Second, cognitive symptoms may elicit occurrence of the other symptoms, a process which results suggest may operate even before depression onset. Results also indicate that cognitive symptom levels may be clinically useful for predicting future depression.
