Psychometric Properties of the Turkish Adaptation of the Yale Physical Activity Survey

This study aimed to examine the convergent validity and test-retest reliability of the Turkish version of the Yale Physical Activity Survey (YPAS-TR). Eighty-one volunteer older adults were included in the study. Test-retest reliability was evaluated using the intraclass correlation coefficient. Correlation coefficients between YPAS-TR and Physical Activity Scale for the Elderly (PASE), Short Form-36, and Short Physical Performance Battery were examined for convergent validity. Acceptable intraclass correlation coefficient values were reached for YPAS-TR energy expenditure, total physical activity time and summary, vigorous, leisurely walking, moving, standing, and sitting indices (intraclass correlation coefficient = .96-.99). There was a moderate correlation between energy expenditure and total physical activity time with PASE (leisure time activities), PASE (household activities), and PASE (total) (r = .478, r = .468, r = .570, r = .406, r = .490, r = .550, respectively, p < .001). Also, a weak correlation was found between summary and leisurely walking index with PASE (household activities), standing index with PASE (leisure time activities), and PASE (total) (r = .285, p = .010; r = .257, p = .021; r = .238, p = .033; r = .283, p = .010; respectively). The results of the study suggest that the YPAS-TR is a valid and reliable measurement tool that can be used to assess the physical activity patterns of Turkish older adults.

Automated summary

This study examined the reliability and validity of the Turkish version of the Yale Physical Activity Survey (YPAS-TR) in older adults. The results showed that the YPAS-TR is a valid and reliable measurement tool for assessing physical activity patterns in Turkish older adults.
