Despite evidence of ethnic differences in family caregivers' experiences, the extent to which caregiver interventions are culturally tailored to address these differences is unknown. A systematic review of literature published from 1980 to 2009 identified: differences in caregiving experiences of African American, Latino, and Chinese American caregivers; psychosocial support interventions in these groups; and cultural tailoring of interventions. Ethnic differences in caregiving occurred at multiple levels (intrapersonal, interpersonal, environmental) and in multiple domains (psychosocial health, life satisfaction, caregiving appraisals, spirituality, coping, self-efficacy, physical functioning, social support, filial responsibility, familism, views toward elders, use of formal services and health care). Only 18 of 47 intervention articles reported outcomes by caregiver ethnicity. Only 11 reported cultural tailoring; 8 were from the Resources for Enhancing Alzheimer's Caregiver Health (REACH) initiative. Cultural tailoring addressed familism, language, literacy, protecting elders, and logistical barriers. Results suggest that more caregiver intervention studies evaluating systematically the benefits of cultural tailoring are needed.
