“…In addition, the advantage of rotator-cuff measures has not been proven to date in the shoulder-related literature. [19][20][21] Although the main value of the multiple-domain measures is in their ability to document the impact of disease on each QOL domain, we do not have supporting evidence for the specificity of information from each domain or sub-scale. 22,23 Several other shortcomings specific to the WORC can be noted.…”

Purpose: The objective of this study was to develop and examine the measurement properties of a shortened version of the Western Ontario Rotator Cuff Index (WORC), the SHORTWORC, in individuals with rotator-cuff pathology. Methods: The study occurred in two stages, both using secondary analysis of existing data sets. The first stage used cross-sectional data from candidates for rotator-cuff surgery to develop the SHORTWORC. The second stage examined various measurement properties of the SHORTWORC by analyzing scores from the WORC, the American Shoulder and Elbow Surgeons questionnaire, and the Constant-Murley score obtained from patients before and after rotator-cuff surgery. Approaches to validating the SHORTWORC included calculating the standard error of measurement (SEM) at an instant in time, performing a confirmatory factor analysis, correlating findings among the questionnaires, and examining differences between men and women. Sensitivity to change was investigated using standardized response mean and relative efficiency. Results: Data for 712 patients were used to develop the SHORTWORC, the final version of which consisted of 7 questions. Data for 166 patients (86 men, 80 women; mean age 57 e 11 years) were used for validation. The SEM based on internal consistency (SEM IC ) was calculated as 7.43 SHORTWORC points. The SHORTWORC had similar convergent validity (r ¼ 0.72 À 0.82) and sensitivity to change (SRM ¼ 1.20 vs. 1.25, p > 0.05) to the longer version. The relative efficiency of the SHORTWORC was 3.19 times that of the WORC (95% CI, 1.50-71.51) in discriminating men's from women's level of disability. Conclusions: The SHORTWORC has indicators of validity, relative efficiency, and sensitivity to change comparable to those of the original version but has a smaller response burden.Key Words: outcome measures; reliability of results; shortened version; validity of results; WORC.

“…2 The Upper Extremity Functional Index (UEFI) is a patient-reported outcome measure (PROM) for quantifying UE function 3 that has been used in several studies of people with musculoskeletal UE problems. [4][5][6][7][8] Recently, we performed a Rasch analysis of the tool that informed its modification to a 15-item interval-level PROM (UEFI-15). 9 Psychometric properties of the UEFI-15 have not been compared to the original version, nor has the positive minimal clinically important difference (pMCID) been determined for either measure.…”

Purpose: To examine the reliability, validity, and sensitivity to change of the 20-item version and the Rasch-refined 15-item version of the Upper Extremity Functional Index (UEFI-20 and UEFI-15, respectively) and to determine the impact of arm dominance on the positive minimal clinically important difference (pMCID). Methods: Adults with upper-extremity (UE) dysfunction completed the UEFI-20, Upper Extremity Functional Scale (UEFS), Pain Limitation Scale, and Pain Intensity Scale at their initial physiotherapy assessment (Time 1); 24-48 hours later (Time 2); and 3 weeks into treatment or at discharge, whichever came first (Time 3). Demographics, including working status, were obtained at Time 1. Global ratings of change (GRC) were provided by the treating physiotherapist and patient at Time 3. The UEFI-15 was calculated from relevant items in the UEFI-20. The intra-class correlation coefficient (ICC) and minimal detectable change (MDC) quantified test-retest reliability (Time 1-Time 2). Cross-sectional convergent validity was determined by the association (Pearson's r) between Time 1 measures of function and pain. Known-groups validity was evaluated with a one-way ANOVA across three levels of working status. Longitudinal validity was determined by the association (Pearson's r) between function and pain change scores (Time 1-Time 3). Receiver operating characteristic (ROC) curves estimated the pMCID using Time 1-Time 3 change scores and average patient/therapist GRC. Results: Reliability for the UEFI-20 and UEFI-15 was the same (ICC ¼ 0.94 for both measures). MDC values were 9.4/80 for the UEFI-20 and 8.8/100 for the UEFI-15. Crosssectional, known-groups, and longitudinal validity were confirmed for both UEFI measures. pMCID values were 8/80 for the UEFI-20 and 6.7/100 for the UEFI-15; pMCID was higher for people whose non-dominant arm was affected. Conclusions: Both UEFI measures show acceptable reliability and validity. Arm dominance affects pMCID. The UEFI-15 is recommended because it measures only one dimension: UE function.
