Apart from imaging and physical examination for shoulder instability (SI), medical history with patient feedback should be considered to assess the patient's condition and recovery. The aim of this study was to evaluate psychometric properties of the Polish version of Western Ontario Shoulder Instability Index (WOSI)-one of the most frequently used patient-reported outcome measures for SI. During examination 1, 74 patients after arthroscopic repair for SI (age x¯ = 30.01 ± 8.98) were tested. Examinations 2 and 3 involved 71 and 51 patients, respectively. They completed the Polish version of the WOSI, the shortened version of the Disabilities of Arm, Shoulder and Hand Questionnaire (QuickDASH), the Short Form-36 version 2.0 (SF-36 v. 2.0) and 7-point Global Rating Change scale (GRC). The WOSI-PL demonstrated high internal consistency (Cronbach's alpha for total = 0.94), and test-retest reliability (Total ICC = 0.99). High construct validity was found (89%) as the a priori hypotheses were confirmed. All domains and total scores of WOSI-PL showed a moderate to strong degree of responsiveness (ES = 0.37-0.44; SMR = 0.87-1.26). Minimal clinically important difference (MCID) for the Total WOSI-PL was 126.43 points/6% (95%CI 67.83-185.03) by the anchor-based method and 174.05 points/8% (95%CI 138.61-233.98) by the distribution-based method. The Polish version of the WOSI can be considered a reliable, valid and responsive PROM. It is recommended for assessing the quality of life in patients after arthroscopic repair for SI and can be applied in research and in the clinical setting for monitoring treatment and facilitating patient-centred therapeutic decisions.
除了肩关节不稳定（SI）的影像学和体检外，还应考虑患者的病史和反馈，以评估患者的病情和恢复情况。本研究的目的是评估波兰版 Western Ontario Shoulder Instability Index（WOSI）的心理测量特性——这是最常用于评估 SI 的患者报告结果测量之一。在检查 1 中，对 74 名接受关节镜修复 SI 后的患者（年龄 x¯=30.01±8.98）进行了测试。检查 2 和 3 分别涉及 71 名和 51 名患者。他们完成了波兰版 WOSI、简化版 Disabilities of Arm, Shoulder and Hand Questionnaire（QuickDASH）、Short Form-36 version 2.0（SF-36 v. 2.0）和 7 分整体变化量表（GRC）。WOSI-PL 表现出较高的内部一致性（总 Cronbach's alpha 为 0.94）和测试-重测信度（总 ICC=0.99）。高结构效度（89%）得到验证，即先验假设得到确认。WOSI-PL 的所有领域和总分均表现出中度至高度的反应性（ES=0.37-0.44；SMR=0.87-1.26）。基于锚定的方法，总 WOSI-PL 的最小临床重要差异（MCID）为 126.43 分/6%（95%CI 67.83-185.03），基于分布的方法为 174.05 分/8%（95%CI 138.61-233.98）。波兰版 WOSI 可视为一种可靠、有效且反应灵敏的 PROM。它推荐用于评估关节镜修复 SI 后患者的生活质量，可应用于研究和临床环境，以监测治疗并促进以患者为中心的治疗决策。
