“…However, in each case, where EFA identified the conceptualized “Pain” and “Disability” subscales, the demarcation between them was also found to be quite unclear. The different contexts, sample sizes, and techniques characterizing previous studies exploring the scale structure of the SPADI and most recently, a Persian version of the OSS36 (which used different analytic techniques and presented broadly similar findings) underline the importance of this study’s findings, where a direct comparison of these two measures was made possible within one large-scale study. The techniques used (based on recommended polychoric correlations) to surmise the optimal number of underlying domains, use of oblique rotation in EFA, and additional assessment of the fit of resulting hypothesized models represent a comprehensive and meticulous assessment, which gives confidence to the findings.…”

BackgroundTo explore and compare the factor structure of the 12-item Oxford shoulder score (OSS) and 13-item shoulder pain and disability index (SPADI).MethodsExploratory factor analysis (EFA) and confirmatory factor analysis (CFA) of data from 660 patients attending 46 hospitals in the UK. Complete OSS and SPADI data were available for 648 (98.2%) and 628 (95.2%) participants, respectively.ResultsFor both instruments, either one or two factors were indicated, depending on the extraction method. On EFA, most OSS items loaded saliently on either of two “Pain” (4 items) and “Function” (8 items) factors, although some items cross-loaded. Cronbach’s alphas were 0.75, 0.90, and 0.91 for “Pain” and “Function” subscales, and all 12 OSS items, respectively. CFA suggested marginally better fit for two factors, with neither one- nor two-factor models rejected. EFA indicated two factors for the SPADI, with three of the eight “Disability” items contributing to an 8-item “Pain factor”, with 2 items within the 5-item “Disability factor” cross-loading. Cronbach’s alpha was 0.87 and 0.93 for the original 5- and 8-item pain and disability scales; 0.94 for all 13 SPADI items, respectively. CFA suggested marginally better fit for the two-factor (original conceptualization) model of the SPADI, with neither one- nor two-factor models rejected.ConclusionEFA and CFA demonstrated that, in addition to single summary scales usage, separate information on pain and self-reported disability/function can be extracted in a meaningful way, as subscales, from both the OSS and the SPADI. This information can help researchers in choosing primary study endpoints appropriately.

“…Floor and ceiling effects were found in 1.2% and 5.1% of patients with rotator cuff diseases and in 2% and 9.3% of patients with shoulder instability in one study (172); floor and ceiling effects were found in 21% and 6.1% of patients in a study of people with rotator cuff disease (172); and ceiling effects were found in 15.3% of patients who had undergone shoulder arthroplasty, but no floor effects were found (173). No floor or ceiling effects were found in Iranian patients with a variety of shoulder disorders (169), whereas 1.8% floor and 13.6% ceiling effects were observed among Dutch patients with various shoulder disorders (166).…”

BackgroundThe Oxford Shoulder Score (OSS) is a simple and reliable, joint-specific, self-reported outcome measure. It can be applied in patients with shoulder disease other than instability. The purpose of this study was to perform a translation, cultural adaptation of the Polish version of the OSS and to evaluate its selected psychometric properties in patients after arthroscopic rotator cuff repair.MethodsSixty-nine subjects participated in the study, with a mean age 55.5 (ranging from 40 to 65 years). The OSS has been translated using the widely accepted guidelines. All patients completed the Polish version of OSS (OSS-PL), the short version of the Disabilities of Arm, Shoulder and Hand Questionnaire (QuickDASH), the Short Form-36 v. 2.0 (SF-36) and the 7-point Global Rating of Change Scale (GRC).ResultsHigh internal consistency of 0.96 was found using Cronbach’s alpha coefficient. Reliability of the OSS resulted in Intraclass Correlation Coefficient (ICC) = 0.99, Standard Error of Measurement (SEM) = 1.14 and Minimal Detectable Change (MDC) = 3.15. The validity analysis showed a moderate (General health r = 0.34) to high (Physical role functioning r = 0.82) correlation between the OSS-PL and SF-36 and a high correlation between the OSS-PL and the QuickDASH (r = − 0.92).ConclusionsThe Polish version of OSS is a reliable and valid, self-reported questionnaire, which can be applied in patients with a rotator cuff tear undergoing reconstruction surgery. The very good psychometric properties of the Polish version of the OSS indicate that it can be used in clinical practice and scientific research.
