Abstract
Introduction:
The aim of this study was to translate, and validate the Persian version of the Anterior Cruciate Ligament–25 (P-JACL–25) questionnaire in individuals who underwent ACL reconstruction surgery.
Martials and Methods: The questionnaire was translated according to international guidelines, after which its content and face validity were assessed by experts and a sample of 30 patients and subsequently, in a cross-sectional study involving 91 participants, the JACL-25 questionnaire was completed alongside the IKDC and TSK questionnaires. Convergent validity was assessed using Pearson's correlation coefficient. Reliability was evaluated through internal consistency and test-retest reliability, with Cronbach's alpha employed to evaluate internal consistency and the intraclass correlation coefficient (ICC) utilized for test-retest reliability.
Results: The findings indicated that the Persian version of the JACL–25 questionnaire has a strong correlation with the IKDC questionnaire and a moderate correlation with the TSK questionnaire. Furthermore, the Persian version demonstrated acceptable reliability, with a Cronbach's alpha (α = 0.972) and an intraclass correlation coefficient (ICC = 0.93). No ceiling or floor effects were observed in this version.
Conclusion: The Persian version of the JACL–25 questionnaire is a valid and reliable instrument for assessing the psychological and functional performance of individuals following ACL reconstruction surgery. This scale can assist sports coaches and rehabilitation professionals in determining whether athletes are ready to return to sports activities.
