OBJECTIVES: The EQ Health and Wellbeing (EQ-HWB) is a novel measure which conceptually overlaps with the five-level EQ-5D (EQ-5D-5L) while capturing broader dimensions of health and wellbeing. This study aims to explore the extent to which the EQ-HWB and EQ-5D-5L capture overlapping or complementary constructs, as well as to explore the discriminative ability of the short-form EQ-HWB (EQ-HWB-S) as a multi-attribute utility instrument (MAUI) in the Australian setting. METHODS: A secondary analysis of data from a nationally-representative cross-sectional survey of 2,002 Australian adults was performed. The survey included socioeconomic questions and health characteristics, as well as the EQ-HWB and EQ-5D-5L instruments. Convergent and known-group validity were evaluated through Spearman rank correlation and multivariable regression analyses, respectively. An exploratory factor analysis (EFA) was also performed to explore the underlying constructs of the two measures. RESULTS: Correlation coefficients varied from moderate to strong (rs ≥ 0.40) between the EQ-5D-5L and the corresponding EQ-HWB dimensions (all P<0.001). Based on the EFA, both instruments measure similar underlying constructs, with the EQ-HWB capturing broader aspects of wellbeing. The known-group analysis demonstrated the relative discriminative ability of the EQ-HWB-S in capturing broader aspects of health and wellbeing. CONCLUSIONS: The EQ-HWB was at least moderately correlated with the EQ-5D-5L in overlapping domains/dimensions and demonstrated greater sensitivity in participants with mental health problems versus the EQ-5D-5L. Our findings support future research exploring the value of the EQ-HWB-S as a MAUI for the general Australian population.
