Objectives: To measure the quality of life in patients according to virtual cerebral palsy severity by using the Korean version of EQ-5D-Y proxy, Visual Analogue Scale (VAS), and Time Trade-Off method (TTO).
Methods: The study was conducted in parents of children and adolescents aged 4 to 15 years in Seoul. We analyzed the difference in the utility value according to five levels of cerebral palsy severity in the Gross Motor Function Classification System (GMFCS) and test-retest reliability.
Results: 1. There were significant differences in VAS, TTO, and EQ-5D-Y proxy according to the cerebral palsy severity (p<.001). 2. VAS was significantly different according to the respondent's visit to the medical institution, the presence of disease in the respondent, a visit to the child's medical institution, the age of the child, and the sex of the child. The value of TTO was significantly different according to the respondent's visit to the medical institution, respondent's sex, and the age of the child. Also, EQ-5D-Y proxy was significantly different according to the age of the child. 3. Intraclass correlation coefficient values were more than 0.6 for both VAS and TTO at all stages. But for the EQ-5D-Y proxy, the value was less than 0.6 at all stages.
Conclusions: The quality of life assessment using EQ-5D-Y proxy showed significant differences in the severity of cerebral palsy. However, large-scale studies using EQ-5D-Y proxy are needed because of low test-retest reliability.
