The aim of this study was to examine the validity of the EuroQOL five dimensions questionnaire (EQ-5D) using a nationally representative data from the National Health Interview Survey (NHIS) through comparison with short-form 36 (SF-36).
Data for this study came from the 2009 NHIS in Taiwan. The study sample was the 4007 participants aged 20-64 years who completed the survey. We used SUDAAN 10.0 (SAS-Callable) to carry out weighed estimation and statistical inference. The EQ index was estimated using norm values from a Taiwanese study as well as from Japan and the United Kingdom (UK). The SF-36 score was standardized using American norm values.
In terms of concurrent validity, the EQ-5D met the five hypotheses. The results did not fulfill hypothesis that women would have lower visual analogue scale (EQ-VAS) scores. In terms of discriminant validity, the EQ-5D fulfilled two hypotheses. Our results approached but did not fulfill hypothesis that there would be a weak association between the physical and psychological dimensions of the EQ-5D and the mental component summary score of the SF-36. Results were comparable regardless of whether the Japanese or UK norm value sets were used.
We were able to fulfill many, not all of our validity hypotheses regardless of whether the established Japanese or UK norm value sets or the Taiwanese norm values were used. The EQ-5D is an effective and simple instrument for assessing health-related quality of life of general population in Taiwan.
本研究旨在通过与简短形式36项健康调查量表（SF - 36）进行比较，利用来自国民健康访问调查（NHIS）的具有全国代表性的数据，检验欧洲五维度健康量表（EQ - 5D）的有效性。
本研究的数据来自2009年台湾地区的国民健康访问调查。研究样本为4007名年龄在20 - 64岁之间且完成调查的参与者。我们使用SUDAAN 10.0（可调用SAS）进行加权估计和统计推断。EQ指数使用来自台湾地区以及日本和英国的研究的标准值进行估计。SF - 36得分使用美国标准值进行标准化。
在同时效度方面，EQ - 5D符合五个假设。结果未满足女性视觉模拟量表（EQ - VAS）得分较低这一假设。在区分效度方面，EQ - 5D符合两个假设。我们的结果接近但未满足EQ - 5D的身体和心理维度与SF - 36的心理成分汇总得分之间存在弱关联这一假设。无论使用日本还是英国的标准值集，结果都是可比的。
无论使用既定的日本或英国标准值集还是台湾地区的标准值，我们都能满足许多而非全部的效度假设。EQ - 5D是评估台湾地区普通人群健康相关生活质量的一种有效且简单的工具。
