psychometric properties of persian version the self-efficacy for exercise scale for older adults

Introduction: The purpose of this study was to determine the psychometric properties of Persian version the self-efficacy for exercise Scale for older adults. Materials and Methods: For this purpose, 352 older adults from two genders (%59 men and %41 women) were chosen by cluster random sample and completed the Persian version the self-efficacy for exercise scale for older adults. At first, data was confirmed with use of translation- retranslation, face validity and translation accuracy methods. Meaningly, for scale construct validity, confirmatory factor analysis and for scale's internal constancy and also infraclass correlations coefficient temporal stability, Cranach alpha coefficient was used. Results: The results show that the model fit index (RMSEA, 0.055; CFI, 0.95 & TLI, 0.94), internal consistency the total scale (0.90) and temporal stability the total scale (0.83) showed Persian version the self-efficacy for exercise scale for older adults have good reliability and validity.. Conclusion: These findings indicated a good validity and reliability for the Persian version of the self-efficacy for exercise Scale and for older adults. Therefore, the Persian version the self-efficacy for exersice scale for older adults can be employed as a tool in order to study and evaluate the efficacy of Iranian men and women for older adults.
