Background and Purpose: In order to effectively evaluate self-efficacy a valid and reliable instrument is clearly required. This study was conducted to assess the psychometric properties of the Persian version of the Exercise Self-Efficacy Scale (ESES) in hemodialysis patients. Methods: There were 202 patients who completed the Exercise Self-Efficacy Scale. The face, content and construct validity were evaluated. The reliability of the scale was measured using internal consistency and construct reliability. Findings: Construct validity determined one factor. The total variance was calculated at 48.13%. The confirmatory factor for the goodness of fit indices was χ2[(27, N=202)=106.70]. All the indices confirmed that the final model was a good fit. The convergent and divergent validity of the scale were regarded as being acceptable. The reliability of the scale was calculated as being over 0.7. Conclusion: Considering the established acceptability of the psychometric properties of the Exercise Self-Efficacy Scale, the Persian version of the scale can be reliably used for measuring self-efficacy in hemodialysis patients.
