Evaluating the hopelessness model of depression: diathesis-stress and symptom components.

The hopelessness model of depression posits that latent attributional diatheses combine with stressors to produce a specific subtype of depression characterized by a specific set of symptoms. Associations between attributional diathesis, stress, and symptoms were examined to test the prediction that hopelessness depressions are characterized by a specific symptom profile. Fifty-seven depressed outpatients were categorized into subgroups on the basis of whether or not they met the criteria of L. Y. Abramson, L. B. Alloy, and G. I. Metalsky's (1988) hopelessness depression, defined as a match in content domain between attributional diathesis and negative stressor. Support for hopelessness depression was mixed. The hopelessness subtype differed from other major depressions with respect to symptom profile. However, the differences in symptomatology were not wholly consistent with the predictions of the hopelessness model.
