The objective of this paper is to report on the origin of the EQ VAS and current understanding of the EQ VAS conceptual framework via a literature search based on the snowball approach.
A review was conducted in two steps: (1) a citation search and (2) a search of the EuroQol group's grey literature.
The findings indicate that the EQ VAS was originally designed as a warm-up task for valuing hypothetical health states. The characters of the EQ VAS reflect its valuation origin, such as drawing a line (the previous version), vertical orientation, and choice of end labels. None of these design elements of the EQ VAS were chosen for the purpose of measuring self-reported overall health. Despite this, the EQ VAS proves to be a valid self-reported health status measure with its psychometric properties demonstrated in various general and clinical populations. We found a dearth of literature addressing the conceptual framework of EQ VAS as a measure of self-rated overall health.
With its potential as a powerful measure of overall health, further research into EQ VAS design, conceptual framework and empirical function is warranted.
本文旨在通过基于滚雪球方法的文献检索，报告欧洲五维度健康量表（EQ - VAS）的起源以及目前对其概念框架的理解。
分两步进行综述：（1）引文检索；（2）检索欧洲生活质量研究组的灰色文献。
研究结果表明，EQ - VAS最初被设计为评估假设健康状态的热身任务。EQ - VAS的特征反映了其评估起源，如绘制线条（早期版本）、垂直方向以及端点标签的选择。EQ - VAS的这些设计元素均不是为测量自我报告的总体健康状况而选择的。尽管如此，EQ - VAS已被证明是一种有效的自我报告健康状况测量工具，其心理测量特性在各种普通人群和临床人群中得到了证实。我们发现，关于将EQ - VAS作为自我评定总体健康状况测量工具的概念框架的文献匮乏。
鉴于EQ - VAS作为总体健康状况有力测量工具的潜力，有必要对其设计、概念框架和实证功能进行进一步研究。
