Cultural adaptation and psychometric adequacy of the Persian version of the physical activity scale for the elderly (P-PASE)

OBJECTIVE: This cross sectional study was conducted to investigate cultural adaption and validation of the Persian version of the PASE among the elderly community dwellers in Iran. Out of 278 elderly people, 65% of them were female. After translation and cultural adaption, the PASE was evaluated with respect to the validity and reliability. Regarding the construct validity, the concurrent validity was assessed between the PASE and ADL, IADL, self-rated health, and TUG test. RESULTS: The mean score of P-PASE was equal to 153.73 ± 48.47. P-PASE scores were significantly and negatively correlated with TUG (r = − 0.691, P < 0.001) and age (r = − 791, P > 0.001), and were also significantly correlated with ADL (r = 0.775, P < 0.001), and IADL (r = 0.161, P < 0.001). The ICC was obtained as 0.92 (95% CI 0.90–0.94), 0.86 (95% CI 0.82–0.87), and 0.91 (95% CI 0.90–0.94) for the leisure time activity, household activity, and work-related activity scores, respectively. The Cronbachs̓ alpha coefficient was equal to 0.74, 0.74, and 0.79, respectively for leisure time activity, household activity, and work-related activity domains.
