This note alerts the readers to the fact that QALYs (quality-adjusted-life-years) do not stem directly from the individual's utility function and thus, at best, only partly reflect an individual's true preferences. This might lead to the choice of the non-preferred alternative due to the misrepresentation of the individual's preference. This is illustrated by using a simple example from Mehrez and Gafni (1989).
本注释提醒读者注意，质量调整生命年（QALYs）并非直接源自个体的效用函数，因此，充其量仅能部分反映个体的真实偏好。这可能会因个体偏好的错误表述而导致选择非偏好的选项。梅雷兹和加夫尼（1989年）给出的一个简单例子说明了这一点。
