Poor interpersonal problem solving as a mechanism of stress generation in depression among adolescent women.

The authors examined C. Hammen's (1991) model of stress generation in depression and the role of interpersonal problem-solving strategies (IPS) in the stress generation process in a longitudinal sample of 140 young women who entered the study at ages 17-18. Structural equation modeling was used to test a model in which IPS and subsequent interpersonal stress mediated the relationship between initial and later depressive symptoms. Results supported the main prediction of the stress generation model: Interpersonal stress mediated the relationship between initial and later depressive symptoms. In addition, IPS predicted interpersonal stress. However, no association was found between depressive symptoms and IPS. An alternative model in which IPS moderated the relationship between stress and depressive symptoms was tested; it was not supported.
