OBJECTIVE: The purpose is to provide more validity, reliability, and responsiveness testing of the anterior cruciate ligament-quality of life instrument (ACL-QOL), particularly in light of consensus-based standards for the selection of health status measurement instruments (COSMIN) guidelines. DESIGN: Prospective case series. SETTING: An orthopedic surgical practice for consultation. @entity1 : A convenience sample of 579 @entity942 @entity1 . INTERVENTION: Anterior cruciate ligament reconstructive surgery. MAIN OUTCOME MEASURES: @entity1 completed the ACL-QOL at initial visit and underwent reconstructive surgery. @entity1 were followed at 6, 12, and 24 months using the ACL-QOL to determine its validity and responsiveness. Cronbach's alpha was used to determine the unidimensionality of the ACL-QOL. A subset of @entity1 took the ACL-QOL twice in a test-retest reliability analysis (intraclass correlation coefficient or ICC 2,k). Another subset of 24-month postsurgical @entity1 measured the success of their surgery using a 7-point global rating scale of improvement as an anchor-based method of responsiveness. RESULTS: Cronbach's alpha coefficients = 0.93, 0.95, 0.96, and 0.98 at 6, 12, and 24 months, respectively. Intraclass correlation coefficient = 0.60, SEM = 6.16, and confidence interval of 12.1 (CI 95%). @entity6372 was measured by comparing the 4 serial time periods. @entity1 improved significantly at each time period (P < 0.05, ETA squared 0.61). A 24-month ACL-QOL was significantly correlated (P > 0.05) to being "significantly better" or "somewhat better." CONCLUSIONS: The results of this study added more validity, reliability, and responsiveness for the ACL-QOL. The ACL-QOL has completed 8 of 9 COSMIN criteria.
