BACKGROUND: The Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale is a 12-item questionnaire assessing psychological readiness to return to sport after anterior cruciate ligament reconstruction. It has been validated for use in adults in multiple languages and in an abbreviated 6-question short form. Additionally, literature has been published using this scale in pediatric and adolescent populations, however it has not yet been validated for use with them. PURPOSE: To validate the ACL-RSI scale for use with pediatric and adolescent patients. STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 2. METHODS: test). Reliability testing was performed by calculating Cronbach's alpha. Floor and ceiling effects were assessed by calculating the number of minimum and maximum scores in the cohort. RESULTS: < .001) Age at surgery, body mass index, and sex were not correlated with either ACL-RSI scale. Cronbach's alpha values of the 12- and 6-item ACL-RSI scales in this population were 0.959 and 0.897, respectively. For both the 12- and the 6-item ACL-RSI scales, no floor or ceiling effects were found as the minimum score (0) was not observed in either version, and the maximum score (100) was only observed twice (3.9%) in both versions. CONCLUSION: The ACL-RSI scale is valid to use with pediatric and adolescent patients. The 6-item scale may be a better choice because it has fewer redundancies and minimizes the risk of questionnaire fatigue.
