A checklist for judging preference‐based measures of health related quality of life: Learning from psychometrics
改编心理测量学中的实用性、信度和效度概念，为判断基于偏好的健康相关生活质量测量工具提供一份清单，帮助设计或评审以健康变化为主要效益指标的经济评价。
There have been a number of published reviews of measures of health related quality of life, but most of this work has been undertaken within a tradition of psychometrics outside of economics. This situation has often resulted in health status measures designed specifically for the purposes of economic evaluation being neglected and portrayed as ‘invalid’. This paper utilizes and adapts the traditional psychometric concepts of practicality, reliability and validity for judging preference-based measures of health related quality of life. The psychometric and economic approaches are most different in relation to validity because they are seeking to measure different concepts. The former seeks to measure health change as perceived by patients, whilst economic evaluation requires a measure of the value or strength of preference for the health change. A checklist is presented to provide guidance in the design or review of economic evaluations using changes in health as the main measure of benefit.Copyright © 1999 John Wiley & Sons, Ltd.
