Abstract:
Objective:To compare the psychometric properties of the EQ-5D-Y and CHU-9D in assessing utility values among Chinese children with general health aged 7-9 years.Methods:A total of 458 children in 4 primary schools in Guangxi and Guizhou were investigated by a questionnaire based on validated Chinese versions of the EQ-5D-Y and CHU-9D.The differences in the measurement results of these two scales were analyzed.Results:The ceiling effect of the EQ-5D-Y scale was significantly higher than that of the CHU-9D scale,both of which demonstrated acceptable internal consistency.The ICC and Bland-Altman scatter plots indicated poor agreement between the EQ-5D-Y and CHU-9D utility value measurements.Both scales exhibited good known-group validity and discriminatory ability,but the CHU-9D was better at distinguishing the health status of children across different ages and genders.Conclusion:The CHU-9D outperforms the EQ-5D-Y in terms of ceiling effect,internal consistency,and known-group validity.The two scales are not interchangeable,and researchers should make informed choices based on the strengths and characteristics of each scale when conducting studies on health-related quality of life in children.
