Abstract

Introduction: Evidence is emerging on the importance of psychological readiness to return to sport after anterior cruciate ligament (ACL) reconstruction. The ACL-Return to Sport after Injury scale (ACL-RSI) is developed to assess this. The purpose of this study was to translate, localize and validate the Persian version of the return to sports questionnaire after anterior cruciate ligament injury (ACL-RSI).
Martials and Methods: The ACL-RSI questionnaire was first translated into Farsi by two teams of bilingual experts. The validity of the content of the Farsi version was quantitatively evaluated by calculating the content validity index (CVI) and the content validity ratio (CVR) using a group of 10 experts. Then, 120 football players who underwent ACL reconstruction answered demographic and injury information questionnaires, ACL-RSI translated questionnaire, Knee Injury and Osteoarthritis Outcome Score (KOOS), Tempa Fear of Movement Scale (TSK-11SV) and quality of life (SF12). Statistical analysis included reliability tests (Cronbach's alpha and retest), construct validity and exploratory factor analysis.
Results: The ACLRSI-Pr showed excellent internal consistency (Cronbach’s alpha 0.82) and was significantlycorrelated with the KOOS ‘quality of life’ (r = 0.70, p < 0.001), ‘symptoms’ (r = 0.53, p < 0.001), ‘pain’ (r = 0.58, p < 0.001), and ‘sports’ (r = 080, p < 0.001) subscales. The ACLRSI-Pr also correlated significantlyith the IKDC (r = 0.72, p< 0.001), TSK (r = − 0.55, p < 0.001) and SF-12 (r = − 0.49, p < 0.001) scores.
Conclusion: The Persian version of the ACL-RSI scale was valid, discriminant, consistent and reliable in football player who had undergone ACL reconstruction. This score could be useful to evaluate the effect of psychological factors on return to sport following ACL surgery.
