摘要
Purpose To assess the construct validity of the CHU9D in an adolescent general population sample. The CHU9D is a new generic preference-based measure of health-related quality of life developed specifically for application in the economic evaluation of health care treatments and interventions for young people. Methods A web-based survey was developed including the CHU9D and HUI2 instruments and administered to a community-based sample of consenting adolescents (n = 710) aged 11-17 years. The practicality, face and construct validity of the CHU9D was examined. The relationship between the CHU9D and HUI2 instruments was assessed by a comparison of responses to similar dimensions and the utility scores derived from the two instruments. Results The CHU9D demonstrated high completion rates. CHU9D was able to discriminate between respondents according to their self-reported general health (Kruskal-Wallis P value <0.001). The mean CHU9D adolescent population utilities were similar to those generated from the HUI2 [Mean (SD) CHU9D utility 0.844 (0.102) and HUI2 utility 0.872 (0.138)], and the intra-class correlation coefficient indicated good levels of agreement overall (ICC = 0.742). Conclusion The findings from this study provide support for the practicality, face and construct validity of the CHU9D for application with adolescents aged 11-17 years.
