This study qualitatively examined the experiences of Mexican-origin women caring for elderly family members in order to identify aspects of familism in their caregiving situations. Data were collected from onetime interviews with 44 caregivers living in the greater East Los Angeles area. Kinscripts guided the framing of familism in this study. Data were analyzed using a grounded theory approach. Caregivers’ descriptions of the Mexican family reflected an idealized view of familism. Caregivers reported a lack of support from others and relying for support on fewer family members than were potentially available to them. Findings suggest that the construct of familism has evolved from its long-standing portrayals in the literature. More research is needed to reexamine familism as a theoretical perspective to explain how Mexican-origin families negotiate and construct elder care over the family life course.
