چکیده [English]

The purpose of this study was to determine validity and reliability of the Persian shortened version of the Falls Efficacy Scale-International (FES-I) in people with multiple sclerosis. In this regard, and to confirm the construct validity of the Persian shortened version of FES-I, 170 (95 male and 75 female) people with multiple sclerosis were recruited by convenience sampling and completed the Persian shortened version of FES-I. First, the face validity and translation accuracy of the Persian version of the questionnaire were confirmed through translation-back translation method. Then, confirmatory factor analysis based on structural equations was used for validation of the structure of questionnaire, Cronbach’s alpha coefficient was used for internal consistency of questionnaire, and intra-class correlation coefficient under test-retest method was used to study temporal reliability of items, and percentile points were used for normalization. Fit indices (RMSEA=0.067, CFI=1.00, TLI=0.99), internal consistency (0.94) and temporal reliability (0.83),all are indicative of good validity and reliability of the Persian shortened version of FES-I. Therefore, the Persian shortened version of FES-I can be characterized as an applicable tool to study and evaluate the fear of falling of Iranian people with multiple sclerosis.
