There is great interest in identifying psychological and social variables associated with depressive symptoms in older adults. The goal of this article is to review the literature on the relationship between social support and depressive symptoms in the elderly and to identify the mechanisms involved in this relationship. The review indicates that both structural and functional dimensions of social support are inversely related to depressive symptoms in elderly persons. In addition, there is evidence supporting both the main effect model and the buffering effect model of social support. It is unclear, however, whether observation of these effects depends on the type of measure used to assess social support. A better understanding of the relationship between social support and depression requires the consideration of more precise dimensions of social support as well as the nature of the Stressors experienced by older people.
