The increasing number of minority older adults, and the subsequent increase in family members providing care to these individuals, highlights the need to understand how cultural values contribute to differential caregiving outcomes. Using the sociocultural stress and coping model as a guiding framework, the current study examined cross-cultural relationships among familism, social support, self-efficacy, and caregiving outcomes and examines how these relationships vary as a function of caregiver background characteristics. Baseline data were collected from 243 participants in the Caring for the Caregiver Network randomized controlled intervention trial. Participants completed measures assessing familism, social support, self-efficacy, positive aspects of caregiving, depression, and burden. African American and Hispanic participants exhibited higher levels of familism compared to Whites. Compared to White participants, African Americans' endorsement of familism predicted more positive caregiving appraisals. African Americans also reported greater levels of social support, which in turn predicted lower burden and depressive symptoms when compared with Whites. Exploratory analyses demonstrated significant associations between familism and self-efficacy. In the Hispanic subgroup, familism varied as a function of acculturation. Results indicate that greater levels of familism and social support may exert a protective influence against adverse psychosocial caregiving outcomes. These findings can be used to inform intervention efforts targeting culturally congruent, family-centered approaches.
