This note reports on a 2000 study of the content validity of the EQ-5D's representation of health for 66 Măori (New Zealand's indigenous people, comprising 14.5% of the population) accessed through cultural networks. Also examined was the construct validity of the health state valuation instrument and its test-retest reliability based on repeated valuations for the two extreme health states. The possibility that the EQ-SD fails to capture what Măori regard as 'health' derives from the so-called 'Măori health model' that augments biological health with mental, spiritual and family well-being. Seventy six percent of respondents considered the EQ-5D's representation of health to be adequate. This proportion is not statistically significantly different from the rates for non-Măori and Măori respectively in an earlier study and might suggest the EQ-5D has content validity for Măori. However, the high prevalence of missing valuations, particularly for dead, and logical inconsistencies suggests that the health state valuation instrument lacks construct validity, although there is evidence of test retest reliability.
本报告介绍了2000年一项关于EQ-5D健康状况表征内容效度的研究，该研究通过文化网络对66名毛利人（新西兰原住民，占人口的14.5%）进行了调查。同时还检验了健康状态评估工具的结构效度及其基于两种极端健康状态重复评估的重测信度。EQ-5D未能涵盖毛利人所认为的“健康”，这种可能性源于所谓的“毛利人健康模式”，该模式在生物健康的基础上增加了心理、精神和家庭幸福感。76%的受访者认为EQ-5D对健康的表征是充分的。这一比例与早期一项研究中非毛利人和毛利人的比例相比，在统计学上没有显著差异，这可能表明EQ-5D对毛利人具有内容效度。然而，缺失评估的高发生率，尤其是针对已故者的评估，以及逻辑不一致性表明，尽管有重测信度的证据，但健康状态评估工具缺乏结构效度。
