BACKGROUND
The Western Ontario Shoulder Instability index (WOSI) is a questionnaire designed to measure health-related quality of life in patients with shoulder instability. The aim of the current study was to translate the WOSI into Hebrew and assess its psychometric properties.
METHODS
The WOSI was translated into Hebrew according to World Health Organization guidelines. Twenty-five patients completed the WOSI and the Disabilities of Arm, Shoulder, and Hand (DASH) questionnaire 2 weeks and 2 months after surgical shoulder stabilization. Internal consistency (Cronbach's α), criterion validity (Pearson's correlation coefficient with DASH), responsiveness, and floor and ceiling effects were assessed.
RESULTS
Cronbach's α was 0.88-0.95 for total WOSI (range 0.68-0.95 for different sections). Strong correlation with DASH score (r = 0.76-0.84) indicated good criterion validity. Changes between baseline and follow-up for WOSI and DASH scores were moderately correlated (r = 0.68), suggesting moderate responsiveness. Some items demonstrated floor and ceiling effects, especially at baseline, but no floor or ceiling effects were observed for total WOSI or for the WOSI sections.
CONCLUSIONS
The results of the current study demonstrate that the Hebrew version of the WOSI is a valid instrument that can be used to assess disability in patients with shoulder instability. Additional studies are warranted to assess its psychometric properties among various subpopulations.
TRIAL REGISTRATION
The study was pre-registered at the ClinicalTrials.gov website, registration number NCT02978365 .
背景
安大略西部肩部不稳定指数（WOSI）是一种旨在衡量肩部不稳定患者健康相关生活质量的问卷。本研究的目的是将 WOSI 翻译成希伯来语，并评估其心理测量学特性。
方法
根据世界卫生组织的指南，将 WOSI 翻译成希伯来语。25 名患者在接受肩部稳定手术 2 周和 2 个月后完成了 WOSI 和手臂、肩部和手部残疾问卷（DASH）。评估内部一致性（Cronbach's α）、效标效度（与 DASH 评分的 Pearson 相关系数）、反应度以及地板和天花板效应。
结果
WOSI 总分的 Cronbach's α 为 0.88-0.95（不同部分为 0.68-0.95）。与 DASH 评分具有很强的相关性（r=0.76-0.84），表明具有良好的效标效度。WOSI 和 DASH 评分在基线和随访之间的变化中度相关（r=0.68），表明具有中度反应度。一些项目表现出地板和天花板效应，尤其是在基线时，但在 WOSI 总分或 WOSI 各部分均未观察到地板或天花板效应。
结论
本研究结果表明，希伯来语版的 WOSI 是一种有效的工具，可用于评估肩部不稳定患者的残疾程度。需要进一步研究来评估其在各种亚人群中的心理测量学特性。
