Social support and self-rated health among caregivers of people with dementia: The mediating role of caregiving burden.

The purpose of this study was to examine the associations between three indicators of social support and self-rated health among caregivers of people with dementia, and whether caregiving burden mediated such associations. Data from the Resources for Enhancing Alzheimer's Caregiver Health II (REACH II; N = 637) was used and multivariate analyses were conducted to test the mediation effects of caregiving burden by PROCESS for v3.2.03. The results revealed that three indicators of social support (received support, social network, and negative interactions) were all significantly associated with self-rated health. Findings also showed that caregiving burden acted as a mediator mechanism through which the associations between social network and self-rated health, negative interactions and self-rated health occurred. Results suggest that there is a need for more comprehensive caregiving assessments as well as multicomponent interventions that include improving and expanding social networks for caregivers of people with dementia. Findings also highlight the importance of minimizing interpersonal conflicts with others and providing more multicomponent programs aimed at reducing caregiving burden.
