Psychometric properties of Persian version the self-efficacy for exercise scale for older adults

Abstract

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;#39s 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.
