Life stressors, social resources, coping, and the 4-year course of unipolar depression.

Little is known about the effects of psychosocial factors on the long-term course of unipolar depression. This article examines the 4-year stability and change in life stressors, social resources, and coping, and their effect on the course of treated unipolar depression among 352 men and women. Depressed patients were assessed at treatment intake and at 1-year and 4-year follow-ups. Over the 4 years, patients improved in symptom outcomes, the quality of social resources, and coping responses; there were some declines in life stressors. Life stressors, social resources, and coping were related to patient functioning concurrently, after controlling for demographics, initial treatment, and initial dysfunction severity. Preintake medical conditions and family conflict consistently predicted poorer long-term outcomes. The findings imply that medical conditions and family conflict are important risk factors that predict poorer long-term outcome of depression.
