Reliability, Validity, and Responsiveness of the Chinese Version of the Knee Injury and Osteoarthritis Outcome Score (KOOS) in Patients with Anterior Cruciate Ligament Reconstruction in Mainland China.

Abstract:

OBJECTIVE:The aim of this study was to perform a cross-cultural adaption of the KOOS into Chinese and to evaluate its psychometric properties in patients with anterior cruciate ligament reconstruction (ACL reconstruction) in mainland China. DESIGN:A cross-sectional study. SETTING:Patients completed the Chinese version of the KOOS and the SF-36 questionnaire three times. We evaluated the reliability, checked the validity, and assessed the responsiveness. PARTICIPANTS:A total of 42 patients who had undergone ACL reconstruction. MAIN OUTCOME MEASURES:The results of the questionnaire survey. RESULTS:The Chinese version of the KOOS was well accepted, with ideal test-retest reliability and internal consistency. The test-retest reliability was significant, with high ICC values ranging from 0.888 to 0.941. Additionally, we found that the internal consistency was adequate, with Cronbach's alpha coefficient ranging from 0.740 to 0.975. All a priori hypotheses were supported by a high correlation between the KOOS and SF-36. Furthermore, responsiveness was demonstrated since the ES and SRM between subscales following ACL reconstruction was found in the expected pattern. CONCLUSIONS:The Chinese version of the KOOS showed psychometric properties demonstrating acceptable reliability and validity similar to the original version. We conclude that the Chinese version is a reliable and valid instrument for research and clinical assessments of ACL reconstruction patients in mainland China. ZIELSETZUNG:Ziel dieser Studie war die Durchführung einer interkulturellen Adaptation des KOOS ins Chinesische und die Auswertung der psychometrischen Eigenschaften des Fragebogens bei Patienten mit Rekonstruktion des vorderen Kreuzbandes (VKB-Rekonstruktion) in Festlandchina. DESIGN:Querschnittsstudie. SETTING:Die Patienten füllten die chinesische Version der Fragebögen KOOS und SF-36 dreimal aus. Wir untersuchten die Reliabilität, überprüften die Validität und beurteilten die Änderungssensitivität. TEILNEHMER:Insgesamt 42 Patienten, bei denen eine VKB-Rekonstruktion durchgeführt worden war. HAUPTZIELKRITERIEN:Die Ergebnisse der Fragebogenerhebung. ERGEBNISSE:Die chinesische Version des KOOS wurde gut aufgenommen und zeigte eine ideale Test-Retest-Reliabilität sowie interne Konsistenz. Die Test-Retest-Reliabilität war signifikant und es wurden hohe ICC-Werte zwischen 0,888 und 0,941 ermittelt. Des Weiteren wurde eine adäquate interne Konsistenz mit einem Cronbach-Alpha-Koeffizienten zwischen 0,740 und 0,975 festgestellt. Alle A-priori-Hypothesen wurden durch eine hohe Korrelation zwischen KOOS und SF-36 untermauert. Außerdem wurde eine Änderungssensitivität nachgewiesen, da die Kennwerte ES und SRM zwischen den Subskalen nach VKB-Rekonstruktion dem erwarteten Muster folgten. SCHLUSSFOLGERUNGEN:Die chinesische Version des KOOS zeigte psychometrische Eigenschaften, die auf eine mit der Originalversion vergleichbare akzeptable Reliabilität und Validität schließen lassen. Daraus folgern wir, dass es sich bei der chinesischen Version um ein zuverlässiges und valides Instrument für Forschungszwecke und zur klinischen Beurteilung von Patienten mit VKB-Rekonstruktion in Festlandchina handelt.
