The purpose of this study was to substantiate and further develop a previously formulated conceptual model of Role Acceptance in Mexican American family caregivers by exploring the theoretical strengths of the model. The sample consisted of women older than 21 years of age who self-identified as Hispanic, were related through consanguinal or acquired kinship ties to an elder, and had provided at least one intermittent service (without pay at least once a month). A comparative analysis method was used to test the existing theory, which consists of four phases: (a) Introduction/Early Caregiving Experiences, (b) Role Reconciliation, (c) Role Imprint, and (d) Providing/Projecting Care. Results substantiated and elaborated all four phases and 14 categories of the existing model. This study provides further evidence that the intergenerational caregiving Role Acceptance model can be used to study Hispanic caregivers in varied geographic locations. It also provides a framework for comparison with other groups of caregivers. In addition, results inform health professionals about the ways in which Hispanic caregivers view caregiving. This information has the potential to increase cultural competence in the delivery of health care to elders and their families. (Contains 3 tables, 1 figure and 3 footnotes.)
