It also aims to validate the Athlete Psychological Strain Questionnaire (APSQ) in the context of Iranian society. This descriptive survey was conducted on a population consisting of Iranian male and female sportspersons (16 to 40 years old), of whom 300 sportspersons were selected as the sample using snowball sampling. The tools used in this study were the APSQ, Kessler-10 Scale, and Ryff Mental Well-Being Scale, which were used online. SPSS 23 and AMOS 22 were used for data analysis. Confirmatory factor analysis (CFA) was utilized to assess the validity of the questionnaire, while the reliability of the questionnaire was examined through the application of Cronbach's alpha coefficient. Furthermore, Pearson's correlation test was employed to assess the concurrent validity of the questionnaire. Furthermore, discriminant analysis and ROC curve were utilized for examining the discriminant validity and cut-off point.</p></div><div><h3>Findings</h3><p>Results indicate that sportspersons who had stopped playing sports during the COVID-19 pandemic suffered more psychological strain than those who continued playing sports during this period.

The psychometric validation of the APSQ was confirmed in Iranian athletes.
