Determining the Validity and Reliability of Persian Version of for Adolescent Athletes (PSRS-AA)

Introduction: Reactivity to stress is the basis of individual differences in mental, emotional, and physiological responses to stressful situations and is a valid indicator for current and future adverse health outcomes. Despite the importance of stress reactivity and its consequences, the conventional physiological calculation of reactivity is time-consuming, costly, and invasive. This study aimed to determine the validity and reliability of the Persian version of the Perceived Stress Reactivity Scale for Adolescent Athletes (PSRS-AA).Methods: The research method was a descriptive-correlational type. The statistical sample was made up of 290 athletes (130 girls and 160 boys) of different sports fields with an age range of 12 to 20 years who participated in the present study using the available sampling method. First, the correctness of the translation of the Persian version of the questionnaire was confirmed using the back-translation method, and then confirmatory factor analysis based on structural equation modeling was used to determine the validity of the questionnaire, and Cronbach's alpha coefficient was used to determine the internal consistency.Results: The results showed that the goodness of fit index and the comparative fit index are higher than 0.9. Cronbach's alpha coefficient for perceived stress reactivity scale for adolescent athletes and its dimensions were obtained above 0.7 (acceptable index value).Conclusion: Based on the results, based on the results, the Persian perceived stress reactivity scale for adolescent athletes has good and acceptable construct validity and internal reliability, and it can be used as a valid and reliable tool.
