Social relations and depressive symptomatology: self-efficacy as a mediator.

This study investigates general and social self-efficacy as possible mediators of the relationship between quantity and quality of social relations and depressive symptomatology. Mediation models were examined using a regionally representative sample of middle-aged (35-59) and older adults (60+). Hierarchical regression analyses, controlling for age, race, sex, education, health, and family composition, revealed partial mediation for several social relations predictor variables. Whereas general self-efficacy acted as a partial mediator for only middle-aged adults, social self-efficacy was a partial mediator between social relations and depressive symptomatology only among older adults. Findings suggest that self-efficacy may function as a mechanism through which social relations influence depressive symptoms, and that the importance of this mechanism as domain-specific or domain-general may vary with age.
