目的探讨生活质量评估量表（Assessment of Quality of Life，AQoL-8D）的信度和效度。方法采用澳大利亚和美国的多量表比较调查数据，对生活质量评估量表的信度、效度和效度进行了检验。以EQ-5D、SF-6D、健康效用指数（HUI）3、15 D和幸福感质量（QWB）等5个多属性效用（MAU）工具以及SF-36和3个主观幸福感（SWB）指标等4个非效用工具作为比较工具，对预测效度和内容效度进行比较。一个单独的三部分澳大利亚调查被用来评估重测信度。结果结果表明，AQOL-8D相关性更高的SWB工具和SF-36的心理社会维度，它是类似于其他MAU工具的收敛和预测效度。第二次澳大利亚调查显示了较高的重测信度。结论结果表明，AQoL-8D是一种可靠且有效的工具，为目前用于经济评估研究的MAU工具提供了替代方案，并且特别适合当心理社会因素对健康至关重要时。
Objective The purpose of this paper was to report tests of the validity and reliability of a new instrument, the Assessment of Quality of Life (AQoL)-8D, which was constructed to improve the evaluation of health services that have an impact upon the psychosocial aspects of the quality of life.Methods Australian and US data from a large multi-instrument comparison survey were used to conduct tests of convergent, predictive and content validity using as comparators five other multi-attribute utility (MAU) instruments-the EQ-5D, SF-6D, Health Utilities Index (HUI) 3, 15D and the Quality of Well-Being (QWB)-as well as four non-utility instruments-the SF-36 and three measures of subjective well-being (SWB). A separate three part Australian survey was used to assess test-retest reliability.Results Results indicate that AQoL-8D correlates more highly with both the SWB instruments and the psychosocial dimensions of the SF-36, and that it is similar to the other MAU instruments in terms of its convergent and predictive validity. The second Australian survey demonstrated high test-retest reliability.Conclusions The results indicate that the AQoL-8D is a reliable and valid instrument which offers an alternative to the MAU instruments presently used in economic evaluation studies, and one which is particularly suitable when psychosocial elements of health are of importance.
