Cross-cultural adaptation and validation of the short version of anterior cruciate ligament return to sport after injury scale to Persian Language.

Abstract

Many athletes who have anterior cruciate ligament reconstruction (ACL-R) surgery strive to resume their sport at the level they played before the injury. The purpose of this study was to analyze the short Anterior Cruciate Ligament-Return to Sport after Injury scale (ACL-RSI) version's cultural adaptation and validity to Persian language. To evaluate test-retest reliability, 140 participants completed the Persian short version of the ACL-RSI twice, with a 7- to 10-day interval between assessments. Also, Internal consistency, and construct validity were assessed. The findings indicate that the measure demonstrates excellent test-retest reliability (intraclass correlation coefficients = 0.92 [0.86 - 0.95]) and strong internal consistency (Cronbach's alpha = 0.91). Also, the standard error of measurement and minimum detectable change were determined to be 5.11 and 10.69, respectively. The Persian short version of the ACL-RSI exhibited a strong correlation with the ACL-RSI (P <.001, r =.77), a moderate correlation with the Injury Psychological Readiness to Return to Sport Questionnaire (I-PRRS) (P =.03, r =.51) and a strong negative correlation with the Tampa Scale of Kinesiophobia (TKS) (P <.001, r = -.73). Additionally, this short version of the ACL-RSI demonstrated a strong correlation with the International Knee Documentation Committee Subjective Knee Form (IKDC) (P <.001, r =.68) and with the Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales (P <.001, r =.61-0.69). The Persian short version of the ACL-RSI is recommended as a reliable and valid tool for assessing psychological readiness for athletes returning to sport following ACL-R. Not applicable.
