Validation of the RIS Eldercare Self-Efficacy Scale *

This paper presents psychometric data on a new, three-dimensional measure of self-efficacy for caregivers of older adults. Based on a sample of family caregivers of persons with dementia and a longitudinal study design (Time 1: N = 134; Time 2: N = 103), the RIS Eldercare Self-Efficacy Scale assesses relational self-efficacy, instrumental self-efficacy , and self-soothing efficacy . These three dimensions show strong internal consistency and moderate test-retest reliability. Their construct validity is demonstrated by their zero-order correlations with a set of standardized indicators of the caregivers' health and morale, personality characteristics, and personal resources. Multivariate analyses suggest that the three dimensions are more strongly trait- than state-linked. Use of this measure as a clinical screening tool and in intervention research is discussed.
