Abstract
Understanding the behavioral and psychological symptoms of dementia (BPSD) is important for caregivers in long-term geriatric care facilities. In this study performed in 43 long-term care facilities, we evaluated the ability of caregivers to recognize BPSD through the development and validation of self-assessment scales. Reliability and validity of the scales were determined using Cronbach's alpha coefficient, the test/retest method, exploratory factor analysis, confirmatory factor analysis, criteria-related validity, and construct validity. We analyzed cross-sectional data from 310 participants. Factor analysis showed a positive correlation for all scale items (rs = .43–.73). Significant correlations arose from the test/retest method (rs = .48–.76). The α coefficient of all items except one was .70 or more, indicating sufficient reliability. Criteria-related validity (rs = .43–.73) and construct validity (rs = .13–.52) revealed a positive correlation. The BPSD Team Care Self-Assessment Scale is reliable and could ensure BPSD competency in caregivers.
