The Western Ontario shoulder instability index (WOSI) is a disease-specific quality of life measurement tool with 21 items for patients with shoulder instability. Here, we report on translation and validation of the German version of the WOSI according to international guidelines.
A total of 86 patients in three groups were included in this study. In group I, 24 patients underwent surgical stabilization of the shoulder. Preoperatively and at 12 months post-operatively the WOSI, Rowe score, UCLA, Constant score, and the SF-36 were evaluated. In group II, 25 patients were evaluated 2.6 +/- 1.2 years after sustaining a primary traumatic shoulder dislocation. Group III consisted of 37 healthy men and women with normal, healthy shoulders. Evaluation of Pearson's correlation coefficient between WOSI and Rowe score, UCLA, SF-36 and Constant score and for test-retest reliability was made. Moreover, Cronbach's alpha and floor, and ceiling effects were analyzed.
Internal consistency was high (Cronbach's alpha 0.92).Test-retest reliability (Pearson correlation coefficient) was excellent (r = 0.92). The construct validity showed a significant correlation between the WOSI and the scores investigated. There were no floor or ceiling effects for the German WOSI score.
The German translation of the WOSI is a valid and reliable tool, applicable to outcome studies on patients with shoulder instability.
安大略西部肩关节不稳定指数（WOSI）是一种针对肩关节不稳定患者的特定疾病的生活质量测量工具，包含 21 个项目。在这里，我们根据国际准则报告 WOSI 的德文版的翻译和验证情况。
本研究共纳入三组 86 例患者。在第 I 组中，24 例患者接受了肩关节的手术稳定治疗。术前和术后 12 个月，评估了 WOSI、Rowe 评分、UCLA、Constant 评分和 SF-36。在第 II 组中，25 例患者在初次创伤性肩关节脱位后 2.6 ± 1.2 年接受了评估。第 III 组由 37 名肩部正常、健康的男女组成。评估了 WOSI 与 Rowe 评分、UCLA、SF-36 和 Constant 评分之间的 Pearson 相关系数以及测试-重测信度。此外，还分析了 Cronbach's alpha 和地板、天花板效应。
内部一致性很高（Cronbach's alpha 0.92）。测试-重测信度（Pearson 相关系数）非常好（r = 0.92）。结构有效性显示 WOSI 与所调查的评分之间存在显著相关性。德国 WOSI 评分没有地板或天花板效应。
WOSI 的德文翻译是一种有效且可靠的工具，适用于肩关节不稳定患者的结果研究。
