“…The overall scale and all subscales of the C-RC-QOL were validated with good or excellent test-retest reliability (ICC = 0.824–0.954), and this result was also consistent with other similar studies (ICC = 0.77–0.97) [ 13 , 20 , 43 ]. Specifically, the lifestyle subscale demonstrated the highest ICC (0.954), in part because the daily lives of patients probably did not change much in one week.…”

“…To date, there has been no disease-specific scale available in China that can be used to evaluate patients with RC disorders, a common problem that imposes a considerable burden on the affected person and society. The RC-QOL is a widely used scale to evaluate the functioning status of patients with RC disorders; it has been translated into multiple languages and its reliability, validity and responsiveness have been well established [ 11 , 13 , 20 , 21 , 43 ]. It is meaningful to translate the RC-QOL into Chinese to serve the largest population in the world.…”

BackgroundThe Rotator Cuff Quality of Life Index (RC-QOL) is a scale designed to evaluate the impact of rotator cuff (RC) disorders on the general quality of life of patients. Our study aims to adapt the RC-QOL into Chinese and to assess its reliability, validity and responsiveness in Chinese patients with RC disorders.MethodsFirst, we developed the Chinese version of RC-QOL (C-RC-QOL) through a five-step procedure. Next, the recruited patients gave three rounds of responses to the C-RC-QOL, Medical Outcomes Study Short Form 36 (SF-36) and Oxford Shoulder Score scales (OSS). Then, we calculated the Cronbach’s alpha, standard error of measurement (SEM), minimally detectable change (MDC), intra-class correlation coefficient (ICC), Pearson's correlation coefficient (r), effect size (ES) and standardized response mean (SRM) to evaluate the reliability, validity and responsiveness of the C-RC-QOL respectively. The unidimensionality of each subscale was assessed by principal component analysis (PCA) of the residuals.ResultsOverall, 124 patients with RC disorders successfully completed the first two rounds of the scales, and 108 patients completed the last round of the scales. Good or excellent internal consistency (Cronbach’s alpha = 0.953) was found in the overall scale and subscales of the C-RC-QOL, and good or excellent test-retest reliability (ICC = 0.854) was found as well. The SEM and MDC values of the C-RC-QOL were 4.6 and 12.8 respectively. Moderate, good or excellent correlations (r = 0.452–0.839) were obtained between the physical subscales of the C-RC-QOL and the OSS, as well as the physical subscales of the SF-36; similar results were obtained between the emotion subscale of the C-RC-QOL and the mental subscales of the SF-36 (r = 0.490–0.733), which, illustrated the good validity of the C-RC-QOL. In addition, high responsiveness was observed in the overall scale and subscales of the C-RC-QOL (ES = 1.77, SRM = 1.98). The unidimensionality of five subscales was respected according to PCA of the residuals.ConclusionsThe C-RC-QOL scale is reliable, valid and responsive for the evaluation of Chinese-speaking patients with RC disorders and it would be an effective instrument.

“…The RC-QOL focuses on more physically demanding activities such as mopping the floor, carrying 10lbs etc. unlike the WORC [37]. Furthermore, the scoring for both outcome measures differ as the RC-QOL rates from 0 to 100, with a lower score meaning a lower quality of life, which is the inverse for the WORC [5,37].…”

Background: To evaluate the translations, cross-cultural adaptation procedures and measurement properties of the Western Ontario Rotator Cuff Index (WORC), when it is adapted for different cultures. Methods: A systematic review was performed, considering different cultural adaptions of the WORC accessible through MEDLINE, CINAHL, EMBASE and/or Google Scholar. Included were prospective cohort studies that used an adapted version of the WORC to measure QoL in patients with rotator cuff disorders. All studies were evaluated according to the current guidelines for cross-cultural adaptations and measurement properties. Results: The search retrieved 14 studies that met the inclusion criteria. According to the recommended guidelines for cross-cultural adaptations, 8 studies performed 100% of the steps, 2 studies performed 80% of the steps and 4 studies used previously translated measures. When evaluating the studies' psychometric properties based on the quality criteria, none of the studies reported all recommended measurement properties. All of the studies reported the measurement property of reliability, but none of the studies reported agreement. Internal consistency was fully reported by 15% of studies. Construct validity was reported by 43% of studies. Only one study reported 100% of the cross-cultural adaption guidelines and 83% of the quality criteria. Conclusions: Although the majority of studies demonstrated proper adaptation procedures, testing of the measurement properties were inadequate. It is recommended that the current adapted versions of the WORC undergo further testing before use in clinical practise, and researchers continue to adapt the WORC for different cultures as it proves to be an appropriate instrument for assessing rotator cuff pathology.
