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.

Notes: I undertook with John Brazier a review of the relevant literature and adapted a number of key ideas from the psychology literature that could help inform economists about the performance of qulaity of life instruments in undertaking economic evaluations. This paper helps in the design of quality of life instruments and in the design of evaluations alongside clinical trials. To date (2.7.07) this paper has been cited 31 times.
