The construct validity and responsiveness of the EQ-5D-5L, AQL-5D and a bespoke TTO in acute asthmatics.

ABSTRACT:

Purpose

Measuring quality of life in acute asthmatics is challenging, especially when asthma attacks can occur sporadically. Several questionnaires can be used to measure quality of life in this patient group; however, psychometric testing is limited on questionnaires that can be used to estimate Quality Adjusted Life years. The objective of this study is to assess the construct validity (convergent and discriminative validity) and responsiveness of the EuroQol-5-Dimensions 5-Level (EQ-5D-5L), Asthma Quality of Life Utility Index-5 Dimensions (AQL-5D) and Time Trade-Off (TTO) in acute asthma patients.

Methods

Data from a prospective cohort study were used to test the validity and responsiveness of the EQ-5D-5L, AQL-5D and TTO in asthma patients who were recruited from UK acc
