Measuring Self-Appraised Changes following Participation in an Intervention for Caregivers of Individuals with Dementia.

This study examined the psychometric properties of the Self-Appraisal of Change Scale, a measure designed to capture domains that are subjectively relevant to caregivers, associated with overall well-being, and amenable to change upon engaging in an intervention. Data from 107 caregivers of veterans with dementia enrolled in a randomized controlled trial of a telephone-delivered caregiver psychoeducation and support group program (the Telehealth Education Program (TEP)) were analyzed. The TEP, which was delivered by master's prepared social workers and a nurse dementia care manager, targeted caregivers' dementia-related knowledge, attitudes, and self-management skills. Analyses were conducted to determine the factor structure, reliability, validity, and measurement invariance of the scale. Factor analyses yielded a single-factor solution for the scale's nine items. The reliability and construct validity of the scale were also supported by the analyses. Multi-group analyses suggested that meaningful comparisons of scale items and total raw scores can be made across usual care (UC) and intervention groups. The findings offer preliminary support that the scale may represent a valid and reliable instrument that captures perceived changes in key domains (e.g. caregiving knowledge, attitudes, and skill) following participation in a psychoeducational and support intervention trial.
