Authors' objectives: Our study aimed to investigate any additional domain more specific to Asian countries while retaining the existing domains of EQ-5D centered on Western society.
Authors' recomendations: We organized candidate domains that could be included in the preference-based HRQoL instrument after reviewing the HRQoL measures and conducted focus group discussion (FGD) targeting the general public, and the questionnaire items were determined through consultation with experts. To examine the practicality of the HRQoL measure, we conducted the survey with nationally representative 1,000 adults aged 19 to 69 in Korea. As the result of FGD, vision, hearing, speaking, memory, sleep, vitality, happiness, and close relationship were established as additional measurement domains. Through survey, the mean EQ-VAS score regarding the health state on the day of the survey was 80.11 (standard deviation 12.84). Among those who did not have problems in the EQ-5D's 5 domains, the number of people who reported problems in vitality was 244 (37.2%), happiness 130 (19.8%), and sleep 71 (10.8%). Among them, the number of people who described their self-rated health from "good (level 3)" to "poor (level 5)" was as high as 76 (11.6%). In the quantile mixed regression model, pain/discomfort and anxiety/depression from the EQ-5D domains and vision, sleep, vitality, and happiness from the additional domains showed statistical significance. Also, the explanatory powers increased. Among the additional 8 domains, the group with vitality had a higher probability of having good self-rated health and also showed statistical significance. Additionally, sleep and happiness demonstrated significance when "good" self-rated health was used as a dependent variable. Vitality, sleep and happiness were significant additional factors for new HRQoL domains. However, since many other factors may exist outside of HRQoL domains, various aspects should be considered when developing a new tool that can more accurately evaluate Asian quality of life.
