“…However, the Dutch translation we used was made by another independent institution using international translation guidelines. 49 Furthermore, the results obtained in each of the diagnostic groups are comparable with previously (but separately) published average scores, 18 SDs,7,18,37,40,42 Cronbach as, 18,48 correlations with the CS 21,40,48 and DASH, 26,48 and ICCs 18,26 of the original WORC in patient groups with similar diagnoses. Therefore, we think this study can be considered to be the first to extensively assess the validity of the WORC according to the Scientific Advisory Committee guidelines in a strictly defined patient group covering a broad spectrum of rotator cuff conditions.…”

“…Internal consistency was measured through Cronbach's α, which yielded a value of 0.96 for the total WORC index score. This is comparable to results obtained in other versions of the WORC index and in the original English version (1,2,3,4,5,6,7,8). However, this high result could be influenced by the similarity between questions.…”

Background: The Western Ontario Rotator Cuff Index (WORC) is an assessment tool developed to evaluate quality of life in patients with rotator cuff disease (RCD). The purpose of this study is to translate the WORC index into Spanish and to evaluate its reproducibility and internal consistency in patients with RCD. Methods: Following guidelines from literature, the WORC index was translated. Sixty patients with RCD were asked to complete the questionnaire. To evaluate reliability, they were asked to answer it for a second time within the next 14 days. The Cronbach’s α (CA) and the intraclass correlation coefficient (ICC) were calculated to determine test-retest reliability and internal consistency. Bland-Altman plot and reliable change index (RCI) were used to evaluate measurement error. Results: Cronbach’s α was 0.96 for the total WORC score (ranges 0.85-0.94 for the five domains).Excellent test-retest reliability was seen with an ICC of 0.98, with the domains ranging between 0.91-0.97. The Bland-Altman plot showed no systematic differences, and the RCI for the total WORC index was 7.6%. Conclusion: The Spanish version of the WORC index is a valid and reliable tool for evaluating quality of life in patients with RCD and may be used in Spanish speaking countries like Colombia. Level of evidence: Basic Science Study, Development or Validation of Outcomes Instruments/Classification Systems.

“…The 14 versions represent 11 different languages/cultures; Chinese [15], Dutch [16][17][18], French-Canadian [13], Japanese [19], Norwegian [20], Persian [21], Polish [22], Portuguese-Brazilian [23,24], Spanish [25], Swedish [26] and Turkish [27]. There was more than one study reporting clinimetric testing of the Dutch [16][17][18] and Portuguese-Brazilian [23,24]. All Dutch versions were conducted independently; Wiertsema et al reported on the reproducibility and translations of the WORC [16], Wessel et al…”

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.
