Psychometric Properties of Persian Version of Sport Imagery Ability Questionnaire (SIAQ) among Athlete Students

Purpose: The aim of the present study was to investigate the psychometric properties of the Persian version of the Sport Imagery Ability Questionnaire (SIAQ) among athlete students.
Methods: This study falls under descriptive research and is categorized as a tool validation study. The necessary information was collected cross-sectionally. The study population consisted of athlete students from Farhangian University, Payame Noor University, and Khurasgan Islamic Azad University. They were randomly selected and completed the Sport Imagery Ability Questionnaire (SIAQ), which includes 15 questions and five components: imagery skill abilit, strategy imagery ability, goal imagery ability, affect imagery ability, and mastery imagery ability. Confirmatory factor analysis assessed construct validity, Cronbach's alpha coefficient determined internal consistency, and intra-class correlation coefficient examined test-retest reliability.
Results: The results of the present study indicated a good fit for the Persian version of the Sport Imagery Ability Questionnaire (RMSEA=0.048, CFI=0.911, TLI=0.961, PNFI=0.064, AGFI=0.918). Additionally, internal consistency and test-retest reliability of the Sport Imagery Ability Questionnaire (SIAQ) were found to be acceptable.
Conclusion: Based on the results of this study, the Persian version of the Sport Imagery Ability Questionnaire (SIAQ) demonstrates acceptable validity and reliability among athlete students. Psychologists, athletes, and researchers can utilize this questionnaire in the athlete student community.
