Introduction: Despite the importance of refereeing judgments and the sensitivity of referees' role in holding sports competitions and the impact of referees' decisions on the outcome of the game, little research has been done on various aspects of the referees' profession and occupation. The purpose of this study was to determine the validity and reliability of the Persian version of the self-efficacy scale in referees.Methods: The present research, was a descriptive-correlational study. For this purpose, 228 referees of team and individual sports completed the Persian version of the self-efficacy scale in referees. First, using the open-translation method, the accuracy of the Persian version of the questionnaire was confirmed, and then to determine the construct validity of the questionnaire, confirmatory factor analysis based on structural equation modeling was used, and to determine internal consistency, Cronbach's alpha coefficient was used. Also, for the time reliability of the questions, intra-class correlation with the test-retest method was used.Results: The results showed that the goodness of fit index and the comparative fit index are higher than (0.90). Time reliability (0.76) and Cronbach's alpha coefficient for self-efficacy and its dimensions above 0.7 (acceptable index value) were obtained.Conclusion: Based on the results, the Persian version of the self-efficacy scale in referees has structural validity and internal and temporal reliability desirable and acceptable for referees of team and individual sports and therefore can be used as a valid and reliable tool to assess the self-efficacy of Iranian referees.

Stress is a natural phenomenon in sport competitions. An athlete may maintain good performance and achieve success when he can deal with stress. The present study aimed at examining the validity and reliability of Anshel and Kaissidis’s Coping Style Inventory for athletes. To this end, this questionnaire was translated into Persian in several stages and sent to 7 sports psychologists to examine its content validity based on the criteria of content validity index and ratio. These experts approved the content validity of the Persian version. Subsequently, the questionnaire was distributed among 425 athletes with different skill levels in both team and individual sports. The data were analyzed using confirmatory factor analysis. The results showed good fit of the data to the model (RMSEA=0.048, NFI=0.927, CFI=0.945, X2/df=1.67). The internal consistency of the subscales was examined using Cronbach’s alpha formula. The alpha coefficients were found to be 0.763 and 0.814 for the subscales of approach style and avoidance style, respectively, which indicated good reliability of the scale. It can be concluded that Coping Style Inventory for athletes was an appropriate instrument to study sports stress and coping strategies in Iranian samples.
