Validity and reliability of the Persian version of Perceived Performance in Team Sports Questionnaire (PPTSQ)

Objective criteria for performance measurements are widely used in motor learning, development, and sports psychology, despite their inherent limitations. Due to the limitation in performance evaluation tools in team sports, the present research aimed to determine the validity and reliability of the Persian version of the Perceived Performance in Team Sports Questionnaire (PPTSQ).

The current research was a survey study. The statistical sample consisted of 100 professional athletes (52 women and 48 men) in team sports aged 18 to 32 who participated in the present research through available and purposive sampling. First, the accuracy of the translation of the Persian version of the questionnaire was confirmed using the back-translation method. Then, confirmatory factor analysis based on structural equation modeling was used to determine the structural validity of the questionnaire, and Cronbach's alpha coefficient was used to determine the internal consistency. Statistical analysis was performed using Lisrel software version 8.8.

The results showed that the first-order model is suitable concerning statistical indices (RMSEA=0.079), which confirmed the construct validity of this questionnaire in Persian. The second-order model also confirmed the validity of the constituent components of this questionnaire (RMSEA=0.073). Cronbach's alpha coefficient (α=0.92) and test-retest internal correlation (α=0.92) confirmed the reliability of the questionnaire.

Based on the results, the Persian version of the perceived performance in team sports questionnaire has good and acceptable construct validity and internal reliability, and it can be used as a valid and reliable tool.
