QLU-C10D 测量属性验证：与 EQ-5D-5L 的比较研究

In this study, the measurement properties of QLU-C10D were well validated. The ceiling effects of the dimensions of C10D were lower than those of the dimensions of 5L, which is related to the design of the questionnaire itself. C10D has a better structural width compared to 5L. In this study, even patients who were completely healthy when using EQ-5D-5L reported problems when using disease-specific measurements. Among the 5L, 25 patients chose '1111', but 17 of them did not choose it in C10D (Table 3). In C10D, there were more issues in the dimensions of Physical, Social, and Fatigue. Unlike the study by Norma B. Bulamu et al., we also found differences in the results generated by the two scales in the Physical dimension when patients answered the questions. This is related to the fact that the Physical dimension in C10D contains more content from 5L (mobility, self-care, usual activities). Therefore, there is a considerable overlap in the content of these two scales, and our convergent validity results also indicate higher correlations between theoretically corresponding domains and an overall good association between the index scores.
