title: Adverse life events in elderly patients with major depression or dysthymic disorder and in healthy-control subjects.
abstract: The authors compared elderly outpatients (> or =60 years) with major depression or dysthymic disorder and healthy-control subjects on the type and subjective impact of adverse life events. The Geriatric Adverse Life Events Scale (GALES) was developed for this purpose. Fifty patients with major depression, 79 patients with dysthymic disorder, and 40 healthy controls completed the GALES. Adverse life events during two time periods were assessed: the year before the evaluation, and the year before onset of the index episode (patients only). During the year before evaluation, patients with major depression reported more life events with greater negative impact, particularly for interpersonal conflicts, and dysthymic patients scored intermediate between patients and controls. Sum scores for perceived stress and negative impact on mood differed significantly among the groups: highest for major depression, intermediate for dysthymic disorder, and lowest for controls. During the year before onset, patients with major depression reported significantly higher sum scores for negative impact on mood than patients with dysthymic disorder. On several measures, patients with major depression perceived greater negative impact of life events than patients with dysthymic disorder and healthy controls, particularly for interpersonal conflicts. The subjective impact of adverse life events may play an important role in the expression of depressive illness in elderly patients, particularly in major depression, and it needs to be considered in clinical management.
