This study aimed to evaluate the reliability and validity of the Turkish version of the Home Safety Self-Assessment Tool (HSSAT-T), an instrument designed to help older adults and caregivers systematically identify safety hazards in the home environment. The tool, originally developed as an assessment checklist with supplementary recommendations, was culturally adapted into Turkish following World Health Organization guidelines. A total of 390 community-dwelling older adults aged 65 years and older participated in the study, with psychometric evaluation performed using Rasch analysis. To assess temporal stability, the test was re-administered to 35 participants after 2 weeks. Infit and outfit values ranged from 0.86 to 1.39, confirming acceptable model fit. The KR-20 reliability coefficients for all subdimensions exceeded 0.68, with an overall coefficient of 0.97. Test-retest analysis demonstrated intraclass correlation coefficients above 0.90 for each subdimension. These findings indicate that the HSSAT-T is a psychometrically robust, culturally relevant instrument that can be reliably used in both clinical practice and research to identify and reduce home safety risks among older adults.
