Cultural adaptation and validation of the Polish version of the Physical Activity Scale for the older people living in community

Abstract

Objective: The purpose of this study was cultural adaptation and validation of the Polish version of the Physical Activity Scale for Elderly (PASE) and an assessment of its accuracy and reliability among older people living in south-eastern Poland. Method: This cross-sectional study was carried out among 115 older adults living in southeastern Poland. The original version of the scale has been translated into Polish language following standardized translation procedures. Validity was evaluated by Pearson's rank correlation coefficients between PASE-P and Test Up and Go normal and with cognitive task (TUG; TUGcog), grip strength, basic and instrumental activities of daily living (ADL; IADL), 5 times sit-to-stand test (5x STS), 10-meter walk test (10MWT) and Berg Balance scale (BBS) and International Physical Activity Questionnaire (IPAQ). Results: The mean PASE-P was equal to 91.54 (SD 71.15). Sufficient reliability of the test-retest of the PASE-P questionnaire components was found between the trials. The ICC test was strong and ranged from 0.988 to 0.778 for major domains and total scale score. A significant correlation was found between the total PASE-P score and shorter TUG, TUG cog (r = -0.514, p <0.001; r = -0.481, p <0.001) and 10MWT (r = 0.472, p <0.001). The total PASE-P score was also positively correlated with ADL and IADL (r = 0.337, p <0.001; r = 0.415 p <0.001), BBS (r = 0.537, p <0.001) and 5xSTS (r = 0.558, p < 0.001). Discussion: The results obtained in the study confirm that the Polish version of the PASE scale is a valid and reliable tool for assessing the level of physical activity in older adults living in community.
