Abstract
Background and Purpose: Poor sleep quality is common among family caregivers and contributes to negative physical and mental health outcomes. This study examined the psychometric properties of the Pittsburgh Sleep Quality Index (PSQI) in caregivers of individuals with heart failure (HF) and Alzheimer's disease (AD). Methods: Baseline data from 269 family caregivers were used to assess the psychometric properties of the PSQI. Results: The PSQI showed acceptable reliability (Cronbach's α: HF = .76; AD = .74). Exploratory factor analysis supported a two-factor model in both groups, revealing both shared and condition-specific subscale loadings. Conclusion: Findings support the PSQI's reliability and construct validity in family caregivers, indicating its utility in identifying sleep disturbances in these high-risk populations.
期刊介绍：
The Journal of Nursing Measurement specifically addresses instrumentation in nursing. It serves as a prime forum for disseminating information on instruments, tools, approaches, and procedures developed or utilized for measuring variables in nursing research, practice, and education. Particular emphasis is placed on evidence for the reliability and validity or sensitivity and specificity of such instruments. The journal includes innovative discussions of theories, principles, practices, and issues relevant to nursing measurement.
