Cross-Cultural Adaptation and Measurement Properties of the Arabic Version of the Modified Cinccinati Knee Rating System (MCKRS)
Journal Title: Journal of Surgery Research and Practice - Year 2020, Vol 1, Issue 1
Abstract
Objectives: The Modified Cincinnati Knee Rating System (mCKRS) was designed as an outcome measure to help clinicians gather information about the clinical and functional outcomes of patients after knee surgery. It applies to various knee conditions. Design: Our goal was the translation of the mCKRS to the Arabic language followed by the investigation of its psychometric properties as well as test of its floor/ceiling effects, validity, reliability, and internal consistency. Method: Fifty-seven patients participated in two occasions at the baseline and the follow-up after 2 weeks. We tested for internal consistency with Cronbach’s α. We calculated Spearman’s correlation as a means of estimating construct validity in comparison to the Arabic Knee injury and Osteoarthritis Outcome Score (KOOS). Also, the responsiveness of the mCKRS questionnaire was measured by calculating the standardized response mean (SRM). Results: Overall, the Arabic mCKRS at the baseline had a Cronbach’s α of 0.792, and 0.820 at the follow-up, which was very high and internally consistent. Intra Class correlations (ICC) indicated that the mCKRS questionnaire is reliably reproducible, while Standardized Response Mean (SRM) of the questionnaire with 1.30. This illustrates a high degree of sensitivity regarding the change. Also, we observed a strong correlation with Arabic KOOS (r = 0.760, p < 0.001), indicating that the construct validity was good. Also, all the subscales, except swelling, proved to have a high correlation with Arabic KOOS (r > 0.70). We did not observe any major floor and ceiling effect among all responses. Conclusion: From the results of the study, we can confidently say that the Arabic version of the mCKRS is reliable for diagnosis of knee injuries and produces results similar to those of the original English version.
