There is an interest in the consequences of deriving a single index measure of health for validity and sensitivity. This paper presents the results of testing a recent example of a general health measure designed to derive a single index, the Euroqol (EQ), and presents a comparison with a new, influential profile measure, the Short Form 36 (SF-36) Health Survey Instrument. The EQ and an anglicised version of the SF-36 health survey, both designed for self-completion, were included in a postal survey of a random sample of 1980 patients from two practice lists in Sheffield, UK. The response rate for the EQ questionnaire was 83%, and the rate of completion over 95%. Evidence was found for the construct validity of the EQ dimension responses and the derived total EQ health score in terms of distinguishing between groups with expected health differences. Considerable agreement was found between EQ responses and the total EQ score, and the UK SF-36 profile scores. There was substantial evidence of EQ being less sensitive at the ceiling (i.e. low levels of perceived ill-health) and throughout the range of health states. A recent restructuring of the EQ, may help overcome some of the problems with the physical dimensions by reducing their skewness.
人们对得出单一健康指数衡量指标在有效性和敏感性方面的后果颇感兴趣。本文呈现了对一项旨在得出单一指数的通用健康衡量指标——欧洲五维度健康量表（EQ）的最新示例进行测试的结果，并与一项新的、有影响力的概况衡量指标——简明健康调查问卷（SF - 36）进行了比较。EQ和SF - 36健康调查问卷的英文版本均设计为可自行填写，被纳入对英国谢菲尔德两个诊所名单中随机抽取的1980名患者的邮政调查。EQ问卷的回复率为83%，完成率超过95%。在根据预期健康差异区分不同群体方面，发现了支持EQ维度反应和得出的EQ总体健康得分的结构效度的证据。在EQ反应与EQ总分以及英国SF - 36概况得分之间发现了相当程度的一致性。有大量证据表明，EQ在上限（即低水平的感知健康不佳）以及整个健康状态范围内的敏感性较低。EQ最近的一次结构调整，可能通过减少其偏态性来帮助克服身体维度方面的一些问题。
