Abstract

This paper presents a study to estimate a preference-based single index from the Asthma Quality of Life Questionnaire (AQLQ). Based on the AQL-5D which is a health classification system directly derived from AQLQ, 98 health states were valued by a sample of 307 members of the UK general population. Models were estimated to predict all possible 3125 health states defined by the AQL-5D and compared using a set of criteria. The mean model of main effects was recommended of preferable prediction ability and logically consistent and significant coefficients for levels of dimensions. However, there are concerns over condition-specific valuation issues, such as presenting asthma information to the general public and the choice of condition specific full health as the upper anchor for TTO valuation.
