Abstract

Objective: This study aimed to validate the Geriatric Sleep Questionnaire (GSQ) for assessing subjective sleep quality among elderly individuals in Iran. Methods: The GSQ underwent evaluation for face and content validity. Participants were selected via convenience sampling from five healthcare centers. Sociodemographic variables, including gender, number of children, recreational activities, budget deficits, and family conflicts were analyzed. Confirmatory factor analysis was conducted to verify the results. Internal consistency was assessed using Cronbach’s α, and test-retest reliability was evaluated using the intraclass correlation coefficient (ICC). Results: 200 older adults (mean age 66.8 years) completed the questionnaires. Face and content validity were confirmed by 30 experts (S-CVI/average = 0.96). The final model exhibited good fit indices (χ2/df = 2.89, CFI = 0.96). The scale demonstrated acceptable internal consistency (α = 0.81) and test-retest reliability (ICC = 0.98). Conclusion: The Persian GSQ demonstrates high reliability and validity for assessing sleep quality in older adults, aiding research in this field. © 2024 Taylor & Francis Group, LLC.
