Social ties and psychological well-being in late life: the mediating role of relationship satisfaction.

OBJECTIVE: The current paper examines whether quantitative aspects of social support (i.e., support network characteristics) indirectly influence psychological well-being via older adults' qualitative perceptions of support (i.e., satisfaction with social relationships).
METHODS: A sample of 416 adults aged ≥60 was drawn from the Social Integration and Aging Study, a community-based survey conducted in a small US (Midwestern) city. The survey assessed social networks, social support, and physical and mental health among older adults.
RESULTS: Bootstrapping was used to examine mediation models. Greater support network size predicted lower perceived stress, fewer depressive symptoms, and better life satisfaction, yet this association was fully mediated by relationship satisfaction. For support network composition, greater proportion kin was associated with lower stress and better life satisfaction, though not depressive symptoms, however, relationship satisfaction did not mediate this link. DISCUSSION: Findings highlight the complex interplay of support network characteristics and satisfaction, and suggest the greater import of support satisfaction for older adults' psychological well-being.
