Abstract:
Objective To evaluate the reliability and validity of the Chinese version of European Five-dimensional Five-level Health Scale (EQ-5D-5L) for patients with Kaschin-Beck disease.Methods From May 2017 to September 2018,a total of 245 patients with Kaschin-Beck disease in Yongshou and Linyou counties,Shaanxi Province were interviewed face-to-face with the EQ-5D-5L.The health-related value score was used to calculate the overall health-related quality of life of patients with Kaschin-Beck disease.The higher the score,the better the overall health of the population,and vice versa (-0.391-1.000).The visual analogue system (VAS)score was used to calculate the individual health status,higher scores indicated that the health status of self-evaluation were better,and vice versa (0 to 100 points).Sixty-three patients were retested two weeks later.Evaluation was performed using internal consistency,test-retest reliability,structural validity and criterion validity.Results A total of 245 patients with Kaschin-Beck disease were investigated,including 127 males (51.8％) and 118 females (48.2％),aged (60.37 ± 7.10) years old.The medians and quartile ranges of EQ index and VAS of patients were 0.311 (0.504) and 42.5 (30.0) points,respectively.And the Cronbach coefficient of the five-dimensional score of the health description system was 0.828.The intra-class correlation coefficient (ICC) of each dimension of the health description system was 0.571-0.719.EQ index and VAS score showed that the two had a relatively stable correlation (rs =0.522,P ＜ 0.05),and the ICCs of EQ index and VAS score were 0.754 and 0.570,respectively;the EQ-5D-5L validity calculated by "Therapeutic Efficacy on Kaschin-Beck Disease" (WS/T 79-2011) was between 0.375-0.647 (P ＜ 0.05).Conclusions The overall health status of the Kaschin-Beck disease patient population and the health status of the individual self-evaluation measured by EQ-5D-5L are poor.The reliability test and validity test prove that the EQ-5D-5L is applied to the health status of patients with Kaschin-Beck disease.The EQ-5D-5L has good reliability and validity.
