TRANSLATION AND CROSS-CULTURAL ADAPTATION OF SELF-EFFICACY FOR HOME EXERCISE PROGRAM SCALE IN GUJARATI LANGUAGE FOR MUSCULOSKELETAL CONDITIONS

Background: The objective of this study is to develop and find validity and reliability of cross-cultural adaptation of “Self-Efficacy for Home Exercise Program Scale” in Gujarati language in patients with musculoskeletal conditions. So, that it is feasible and easy to understand for local population of Gujarat. Method: The adaptation involved four steps – forward translation, backward translation, creation of provisional Gujarati version and reliability and validity testing. For validity testing expert panel containing 5 members were selected and their reviews in form of 5-point Likert scale was noted (5-strongly agree, 4- agree, 3- neither agree nor disagree,2- disagree, 1- strongly disagree). Content validity was found for each question based on the reviews of expert panel. For reliability performance of scale was evaluated with 30 patients and repeated to assess test-retest reliability. Result: Out of 12 questions one question went under wording adjustments by the suggestion made by expert panel. The content validity index (CVI) was calculated including I-CVI for each question which ranged from 0.48 to 0.92. S-CVI was found to be 0.8. Reliability was found by test retest score in which Interclass Correlation Coefficient for single measures was 0.971 with 95% of confidence interval (0.941-0.986). Cronbach’s alpha was 0.985 for Gujarati adaptation of SEHEPS scale. Conclusion: Self-Efficacy for Home Exercise Program Scale is cross culturally adapted in Gujarati language and its validity and reliability was found acceptable for use. So, it can be used to measure self-efficacy in Gujarati understanding population. Keywords: Cross cultural adaptation, SEHEPS, Gujarati language, self-efficacy, home exercise program
