Popis:	Objectives: We conducted the cross-cultural adaptation and validation of the Leeds Satisfaction Questionnaire (LSQ) for patients with rheumatoid arthritis (RA) in Korea. Methods: 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). Results: 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. Conclusion: 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.
