The Western Ontario Rotator Cuff Index (WORC) is a joint specific outcome tool that assesses the quality of life in patients with various rotator cuff problems. Our purpose was to evaluate selected psychometric characteristics (internal consistency, validity, reliability and agreement) of the Polish version of WORC in patients undergoing rotator cuff repair.
Sixty-nine subjects took part in the study with a mean age 55.5 (range 40-65). All had undergone arthroscopic rotator cuff repair in 2015-2016. Data from 57 patients in whom symptoms in the shoulder joint had not changed within 10-14 days were analyzed in a WORC test-retest using the Intraclass Correlation Coefficient (ICC), Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC). WORC was compared to the short version of the Disabilities of Arm, Shoulder and Hand Questionnaire (QuickDash) and the Short Form-36 v. 2.0 (SF-36).
High internal consistency of 0.94 was found using Cronbach's alpha coefficient. Reliability of the WORC resulted in ICC = 0.99, agreement assessed with SEM and MDC amounted to 1.62 and 4.48 respectively. The validity analysis of WORC showed strong correlations with QuickDash and SF-36 PCS (Physical Component Summary), while moderate with SF-36 MCS (Mental Component Summary). WORC had no floor or ceiling effect.
The Polish version of the WORC is a reliable and valid tool with high internal consistency for assessing the quality of life in patients undergoing arthroscopic rotator cuff repair.
西安大略肩袖指数（WORC）是一种针对特定关节的结局评估工具，用于评估各种肩袖问题患者的生活质量。我们的目的是评估波兰语版WORC在接受肩袖修复手术患者中的某些心理测量学特征（内部一致性、效度、信度和一致性）。
69名受试者参与了本研究，平均年龄55.5岁（范围40 - 65岁）。所有受试者均在2015 - 2016年接受了关节镜下肩袖修复手术。在WORC重测中，使用组内相关系数（ICC）、测量标准误（SEM）和最小可检测变化（MDC）对57例肩关节症状在10 - 14天内未改变的患者的数据进行了分析。将WORC与手臂、肩部和手部功能障碍问卷简版（QuickDash）以及简明健康状况调查简表第2.0版（SF - 36）进行了比较。
使用Cronbach's alpha系数发现内部一致性较高，为0.94。WORC的信度结果为ICC = 0.99，用SEM和MDC评估的一致性分别为1.62和4.48。WORC的效度分析显示与QuickDash和SF - 36身体成分总结（PCS）有很强的相关性，而与SF - 36心理成分总结（MCS）有中等相关性。WORC没有地板效应或天花板效应。
波兰语版WORC是一种可靠且有效的工具，具有较高的内部一致性，可用于评估接受关节镜下肩袖修复手术患者的生活质量。
