Translation, cross-cultural adaptation and validation of the polish version of the Oxford Shoulder Score in patients undergoing arthroscopic rotator cuff repair

Abstract

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.

Cross-cultural adaptation, validity, and reliability of the Nepali version of the Exercise Adherence Rating Scale: a methodological study

“…The correlation between the total score of 6-item adherence behavior and 10-item reasons for adherence/ non-adherence demonstrated the validity of the N-EARS. The strength of correlation has been used in describing validity in patient-reported outcome measures [6,21]. The 6-item adherence scale demonstrated a strong correlation (0.6-0.8) with items 1, 2, 4, 6, 7, and 10 of 10-item reasons for adherence/non-adherence in the present study.…”

Measures of Adult Shoulder Function

“…The OSS has been translated and culturally adapted in Dutch (176), Italian (170,185), German (187), Brazilian Portuguese (188), Korean (183), French (189), Turkish (40), Chinese (190), Persian (169), Spanish (30), Romanian (184), Danish (191), and Polish (192).…”

“…Cronbach’s α = 0.92 for shoulder problems in Turkish patients (40), Cronbach’s α = 0.93 for in French patients (189), and Cronbach’s α = 0.93 in Chinese patients (190). Cronbach’s α = 0.96 post rotator cuff surgery in Polish patients (192). Cronbach’s α = 0.91 for degenerative or inflammatory shoulder conditions in Korean patients (183) and Cronbach’s α = 0.90 in Brazilian patients (186).…”

Cross-cultural adaptation, validity, and reliability of the Nepali version of the Exercise Adherence Rating Scale: A methodological study

“…The correlation between total score of 6-item adherence behavior and 10-item reasons for adherence/non-adherence demonstrated a validity of the N-EARS. The strength of correlation has been used in describing validity in patient-reported outcome measures [6,21]. The 6-item adherence scale demonstrated strong correlation (0.55 to 0.84) with items 1, 2, 4, 6, 7, and 10 in present study.…”
