Development and testing of the caregiver reciprocity scale.

The purpose of this study was to develop and validate the dimensions of caregiver reciprocity. Social exchange and equity theory served as a conceptual framework for examining recprocal intergenerational exchanges of assistance and support. In the first phase of the study, 12 caregivers of elderly parents, including in-laws, were interviewed to provide narrative data from which items were developed. Content validity was judged by two separate panels of experts. The revised CRS was tested with 303 adult children for reliability and validity, including internal consistency, test-retest reliability, exploratory factor analysis, and convergent and discriminant validity testing using structural equation modeling. Support for construct validity was demonstrated for four factors: Warmth and Regard, Intrinsic Rewards of Giving, Love and Affection, and Balance within Family Caregiving.
