Factor Structure Investigation of the Care-Receiver Efficacy Scale–Short-Form

Abstract

The present study investigated the factor structure invariance of the Care-Receiver Efficacy Scale–Short Form (CRES) using confirmatory factor analysis. Response data were collected from 177 participants across three time points. The analyses of the five-subscale, 25-item CRES at the individual time points indicated that the first-order and second-order models were acceptable. However, Perceptions of Dependence was not a reliable indicator for the higher order factor defined as Overall Care-Receiver Efficacy. The revised 20-item CRES without Perceptions of Dependence had adequate model fit. A series of progressively more constrained models revealed the higher order 20-item CRES can be used as a stable measure of health care self-efficacy for older care-receivers.
