The aim of this study was to determine the validity and reliability of the Persian version of sport perfectionism scale of Dun et al. (2006). To determine the construct validity of the questionnaire, 393 (230 male and 163 female) athletes with different skill levels (novice, non-elite and elite) in 10 team and individual sports were selected by random sampling method and then completed the questionnaire. For this purpose, three sport psychologists and three English teaching experts translated the questionnaire into Persian by translation - back translation method. Then, content and face validity of the Persian version was confirmed (CVI=0.89, VCR=0.93). Confirmatory factor analysis (CFA) based on structural equations model was used to determine the construct validity of the questionnaire; Cronbach alpha coefficient was used to determine internal consistency of the questionnaire and intra-class correlation coefficient under test-retest method with a 2-week interval was used to study temporal reliability of items. The results showed that the primary model of sports perfectionism scale did not support the favorable fit and thus did not confirm the construct validity of the primary model (30 questions). But after eliminating three problematic questions, the second model with 27 questions had acceptable fit indexes (RMSEA=0.08, CFI=0.87), internal consistency and temporal reliability indicating good validity and reliability of the modified Persian version (27 items) of sport perfectionism scale. Therefore, the Persian version of the sport perfectionism scale (modified model of 27 questions) can be used to study and evaluate the personality traits of Iranian athletes.
