: The Western Ontario Shoulder Instability Index (WOSI) is a disease-specific self-administered questionnaire which is designed to measure health-related quality of life for patients with shoulder instability. The objective of this study was to translate and adapt the WOSI questionnaire for the Lithuanian-speaking population and investigate the psychometric properties of the Lithuanian version of the WOSI questionnaire (WOSI-LT): validity, reliability, and responsiveness. : The WOSI scale was translated into Lithuanian using D. E. Beaton's systematic and standardized guidelines for cross-cultural adaptation of patient-administered scales. Subsequently, the psychometric properties of the Lithuanian version of the scale (WOSI-LT) were investigated. The study involved 40 patients who reported shoulder instability and underwent surgical treatment. All patients completed the WOSI-LT, QuickDASH, and SF-12 scales. A subset of 10 patients was selected for the reproducibility and responsiveness evaluation. Based on the obtained data, the reliability, validity, and responsiveness of WOSI-LT were examined using statistical analysis methods. : The Lithuanian adaptation of the WOSI questionnaire exhibited a high degree of internal consistency, evidenced by a Cronbach's alpha of 0.93. Its reproducibility was commendable with an intraclass correlation coefficient (ICC) value of 0.90. When assessing correlations, WOSI-LT demonstrated a stronger relationship with QuickDASH (r = 0.64) than with SF-12 (physical component score (PCS) 0.61, mental component score (MCS) 0.33). Six months post-operation, the responsiveness of the WOSI-LT was particularly notable, with a standardized response mean (SRM) of 0.91, the highest among the three scales. Furthermore, no floor or ceiling effects were identified in the scores of the Lithuanian WOSI. : WOSI-LT is a valid, reliable, and responsive questionnaire that correlates excellently with the original English version of the scale. This scale can be used in Lithuanian medical institutions to assess the severity of patients' shoulder instability and evaluate their progress during treatment.
: 安大略西部肩关节不稳定指数（WOSI）是一种特定于疾病的自我管理问卷，旨在衡量肩关节不稳定患者的健康相关生活质量。本研究的目的是翻译和改编适用于讲立陶宛语的人群的 WOSI 问卷，并研究 WOSI 问卷的立陶宛语版本（WOSI-LT）的心理测量特性：有效性、可靠性和响应能力。 : WOSI 量表是按照 D.E. Beaton 用于跨文化改编患者管理量表的系统和标准化指南翻译成立陶宛语的。随后，研究了该量表的立陶宛语版本（WOSI-LT）的心理测量特性。该研究涉及 40 名报告肩关节不稳定并接受手术治疗的患者。所有患者均完成了 WOSI-LT、QuickDASH 和 SF-12 量表。选择了 10 名患者进行可重复性和响应能力评估。基于获得的数据，使用统计分析方法检查了 WOSI-LT 的可靠性、有效性和响应能力。 : 立陶宛语版 WOSI 问卷具有高度的内部一致性，克朗巴赫α系数为 0.93。其可重复性良好，组内相关系数（ICC）值为 0.90。在评估相关性时，WOSI-LT 与 QuickDASH 的相关性更强（r=0.64），而与 SF-12 的相关性较弱（生理成分评分（PCS）为 0.61，心理成分评分（MCS）为 0.33）。术后 6 个月，WOSI-LT 的响应能力尤为显著，标准化反应均值（SRM）为 0.91，在三个量表中最高。此外，立陶宛语版 WOSI 的评分未出现地板或天花板效应。 : WOSI-LT 是一种有效的、可靠的、有响应能力的问卷，与原始英语版本的量表高度相关。该量表可在立陶宛医疗机构中用于评估患者肩关节不稳定的严重程度，并在治疗期间评估其进展。
