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. ⋯ The EQ-5D-5L and AQL-5D showed stronger construct validity and responsiveness compared to the TTO. Therefore, both the EQ-5D-5L and AQL-5D should be considered for use in future economic evaluations.
