We conducted the cross-cultural adaptation and validation of the Leeds Satisfaction Questionnaire (LSQ) for patients with rheumatoid arthritis (RA) in Korea.
The adaptation of the LSQ from English into Korean was based on guidelines for cross-cultural adaptation for self-report measures. Patients with RA were recruited from an outpatient clinic of a university hospital in South Korea. Validation of the Korean-LSQ with Rasch models was carried out using WINSTEPS. Model fit was determined by Infit and Outfit statistics (≥0.50 and ≤1.50), including the separation index (≥2.00) and reliability index (≥0.80).
The data set comprised 125 patients (82.4% female), with median (interquartile range) age 49.0 (37-57) years, and disease duration of 2.5 (1.2-3.8) years. The total and subscale scores of the Korean-LSQ demonstrated excellent or good test-retest reliability (0.88 for total, 0.71-0.82 for subscales), and items in the scale also revealed a high internal consistency (α = 0.93). The six subscales of the Korean-LSQ were found to have a good fit to the Rasch model and good reliability (Person separation index = 2.63 and reliability index = 0.87; item separation index = 37.03 and reliability index >0.99). In addition, the unidimensionality of the scale was confirmed by the principal component analysis based on the Rasch residuals.
Fit to the Rasch model confirmed that the construct validity, reliability, and unidimensionality of the LSQ were preserved following the adaptation into Korean. The Korean-LSQ is a valid and reliable tool for measuring satisfaction with care in Korean patients with RA.
我们对韩国类风湿关节炎（RA）患者的利兹满意度问卷（LSQ）进行了跨文化调适和验证。
将 LSQ 从英文翻译成韩文是基于自我报告量表的跨文化适应指南。RA 患者从韩国一家大学医院的门诊招募。使用 WINSTEPS 通过 Rasch 模型对韩国-LSQ 进行验证。模型拟合通过 Infit 和 Outfit 统计量（≥0.50 和≤1.50），包括分离指数（≥2.00）和可靠性指数（≥0.80）来确定。
数据集包括 125 名患者（82.4%为女性），中位（四分位间距）年龄为 49.0（37-57）岁，疾病持续时间为 2.5（1.2-3.8）年。韩国-LSQ 的总分和分量表得分具有极好或良好的重测信度（总分 0.88，分量表 0.71-0.82），量表中的项目也显示出较高的内部一致性（α=0.93）。韩国-LSQ 的六个分量表与 Rasch 模型拟合良好，可靠性良好（个体分离指数=2.63，可靠性指数=0.87；项目分离指数=37.03，可靠性指数>0.99）。此外，基于 Rasch 残差的主成分分析证实了量表的一维性。
Rasch 模型的拟合证实，LSQ 在翻译成韩语后保留了结构有效性、可靠性和一维性。韩国-LSQ 是一种有效的、可靠的工具，可用于测量韩国 RA 患者对护理的满意度。
