EQ-5D工具提供了质量调整生命年（Qs）的质量调整权重，该权重基于量化英国公众偏好的调查。然而，这种英国价值观在多大程度上适用于其他国家，特别是非欧洲国家，目前还不清楚。本研究的目的是（a）比较在日本和英国获得的估值，（B）探索日本当地的价值集。采用了缩减研究设计，其中评估了17种假设的EQ-5D健康状态，而英国研究中为42种。该工具的官方日语版本和时间权衡方法被用来采访543名公众。其结果是：首先，在[-1，+1]尺度上，日本和英国获得的评价平均相差0.24，用英国值集预测日本偏好的平均绝对误差（MAE）为0.23。第二，可比较的回归表明，两个民族有系统的不同偏好结构（p
Quality adjustment weights for quality-adjusted life years (QALYs) are available with the EQ-5D Instrument, which are based on a survey that quantified the preferences of the British public. How ever, the extent to which this British value set is applicable to other, especially non-European, countries is yet unclear. The objectives of this study are (a) to compare the valuations obtained in Japan and Britain, and (b) to explore a local Japanese value set. A diminished Study design is employed, where 17 hypothetical EQ-5D health states are evaluated as opposed to 42 in the British study. The official Japanese version of the instrument and the Time Trade-Off method are used to interview 543 members of the public. The results are: firstly, the evaluations obtained in Japan and those from Britain differ by 0.24 on average on a [-1, +1] scale, and mean absolute error (MAE) in predicting the Japanese preferences with the British value set is 0.23. Secondly, comparable regressions suggest that the two peoples have systematically different preference structures (p
