Description: The purpose of this study was to extend the current understanding of relationships among stress, social support, and depressive symptoms of older persons by exploring: (1) the ways in which different types of stressors affect depressive symptoms, (2) the degree to which effects of stressors are mediated by various dimensions of social support, and (3) the mechanism through which social support comes to affect older individuals' depressive symptoms.

The study included stress (negative life events, physical disability, financial strain), various social support elements (social networks, emotional support from significant others, support provided to others), perceived self-efficacy, and depressive symptoms in order to explain the relationship between stress and depressive symptoms in older persons and the degree to which this relationship is mediated through social support and individuals' perceptions of self-efficacy. In particular, it examined the causal relationship between social support and self-efficacy to understand the psychological mechanism through which social relationships affect the well-being of older people.

The study included 925 noninstitutionalized elderly subjects from a 1986 national survey entitled Americans' Changing Lives. Path analysis was used to test the proposed relationships of stress, social support, self-efficacy, and depressive symptoms in the elderly. As hypothesized, stress--negative life events, physical disability, and financial strain--exerted significant effects on depressive symptoms of elderly persons. In addition, the present study demonstrated the following: (1) the effect of negative life events on depressive symptoms was reduced by mobilized social networks or contacts as well as support from important others, (2) physical disability and financial strain further increased depressive symptoms of elderly persons by deteriorating their social networks or contacts, (3) physical disability and financial strain contributed further to increase depressive symptoms by depleting older persons' perceptions of efficacy, and (4) the impact of negative life events on depressive symptoms was reduced by social support from important others and the subsequent positive effect of social support on feelings of self-efficacy in the elderly. The study findings provided useful insight into nursing practice, particularly in planning therapeutic approaches aimed at improving older people's feelings of self-efficacy and supportive social interactions. Limitations of the study and directions for future research were also noted.
