EuroQol data for assessment of population health needs and instrument evaluation (EQ-DAPHNIE)
The EQ-DAPHNIE project represents a significant advancement in generating large, representative, and comparable population health datasets across multiple countries. By employing precise sampling strategies, robust recruitment and data collection methods, and rigorous quality control measures, the project aims to provide a valuable resource for assessing and understanding population health and evaluating various health-related quality of life (HR…
Design and implementation of data quality controls in the EQ-DAPHNIE study
The quality control measures implemented throughout the EQ-DAPHNIE project effectively addressed common issues such as bot responses, speeding, and missing data, resulting in generally high-quality and representative datasets. However, variability across countries underscores the need to account for quality indicators when using the data for norm-setting or cross-country comparisons
Psychometric testing of two respiratory bolt-on items to EQ-5D-5L in patients with obstructive airway diseases
The performance relationship between the EQ-5D-5L composite “Anxiety/Depression” dimension and anxiety and depression symptoms in a large, general population sample
The A/D dimension captures symptoms of anxiety, depression or both equally well. Performance is worse in the younger population. Interpretation in those with a self-reported anxiety or depression disorder should be further investigated. This is the first-of-its-kind large population sample performance analysis, where we present evidence that the performance of the A/D dimension differs between ages, and thus intra-age comparative results may be f…
The relationship between healthcare access and change in health-related quality-of-life among the general population of five countries during the Covid-19 pandemic
Healthcare access was not associated with cumulative differences in change in HRQoL over a 1-year period in strata of age, gender, SES, and chronic disease status
Socio-demographic indicators of self-reported health based on EQ-5D-3L
Background: Generic health-related quality of life instruments, such as the EQ-5D, are increasingly used by countries to monitor population health via general population health surveys. Our aim was to demonstrate analytic options to measure socio-demographic differences in self-reported health using the EuroQol Group's archive of EQ-5D-3L population surveys that accumulated over the past two decades. Methods: Analyses captured self-reported EQ-5D…
Time perspective profile and self-reported health on the EQ-5D
This study identified response heterogeneity stemming from psychological characteristics in self-reported health on the EQ-5D-5L. TP seems to play a double role in self-reported health, firstly as affecting underlying health and secondly as a factor influencing one's response behavior. These findings increase our understanding of the non-health-related factors that affect self-reported health on standardized health status measures
Hungarian population norms for the 15D generic preference-accompanied health status measure
This study provided 15D population norms of the Hungarian general population; furthermore, this is the first study to provide population norms for the 15D in any country. The values established in this study can serve as benchmarks for evaluating efficacy outcomes in clinical trials, quantifying disease burden and identifying unmet needs
What is measured by the composite, single-item pain/discomfort dimension of the EQ-5D-5L? An exploratory analysis
Feasibility and validity of the EQ-5D-3L in the elderly Europeans
With item non-response of less than 3%, good discriminatory, and construct properties, the EQ-5D-3L showed to be a feasible and valid measure in the elderly Europeans
Criteria for developing, assessing and selecting candidate EQ-5D bolt-ons
The criteria generated can be used to guide the development of bolt-ons across different health areas. They can also be used to assess existing bolt-ons, and inform their inclusion in studies and patient groups where the EQ-5D may lack content validity
Psychometric properties of the EQ-5D-5L
Health Inequality Analysis in Europe
Objective: This study explored the additive value of the multi-item EuroQol 5-Dimension 5-Level (EQ-5D-5L) as an outcome measure in health inequality analyses, relative to the single-item EuroQol visual analog scale (EQ VAS). Methods: A sample comprising the general population from Italy, the Netherlands, and United Kingdom (UK) completed the EQ-5D-5L and the EQ VAS. The level of education was selected as a proxy for socio-economic status (SES). …
Health-related quality of life and mental well-being of healthy and diseased persons in 8 countries
The stringency of government response is inversely related to HRQoL and mental well-being with a small positive relation with HRQoL and strong negative relation with mental well-being. The magnitude of effects differed for healthy and diseased persons and by age but was most favourable for diseased and older persons
How to measure fluctuating impairments in people with MS
The newly developed one-week AA of the EQ-5D-5L captures within-day and day-to-day health fluctuations in people with MS. From the patients' perspective, it is a feasible and face valid way to provide important information beyond what is captured by the standard EQ-5D-5L
Does the EQ-5D-5L benefit from extension with a cognitive domain
Adding a cognitive domain to the EQ-5D-5L slightly improved measurement properties and better captured change in health status for trauma patients with TBI and PTSD. Inclusion of the cognitive domain in the EQ-5D-5L when measuring in populations with cognitive problems should be considered
US population norms for the EQ-5D-5L and comparison of norms from face-to-face and online samples
The availability of US EQ-5D-5L norms facilitates interpretation and understanding of general population and patient health
The added value of the EQ-5D with a cognition dimension in injury patients with and without traumatic brain injury
Psychometric performance in general of both the EQ-5D and EQ-5D + C was better in TBI patients. Adding a cognitive bolt-on slightly improved the psychometric performance of the EQ-5D-3L
Health-related quality of life in injury patients
The addition of the cognition dimension increased the explanatory power of the EQ-5D-3L. Although the increase in explanatory power was relatively small after the cognition dimension was added, the decrease of HRQoL (measured with the EQ-VAS) resulting from cognitive problems was comparable to the decreases resulting from other EQ-5D dimensions
Assessment of Health-Related Quality of Life between People with Parkinson’s Disease and Non-Parkinson’s
Background : This study aims to assess the specific difference of the health-related quality of life between people with Parkinson's and non-Parkinson's. Methods : A total of 1710 people were drawn from a prospective study with a smartphone-based survey named '100 for Parkinson's' to assess health-related quality of life. The EQ-5D-5L descriptive system and the EQ visual analogue scale were used to measure health-related quality of life and a lin…
Validity of EQ-5D-5L in stroke
Results support the validity of the EQ-5D-5L descriptive system as a generic health outcome measure in patients with acute stroke, demonstrating some psychometric advantages in comparison with EQ-5D-3L
Comparing responsiveness of the EQ-5D-5L, EQ-5D-3L and EQ VAS in stroke patients
The EQ-5D-5L index, based on the crosswalk value set, seems to be appropriately responsive in patients with stroke, 4 months after disease onset. As far as EQ-5D-5L index is scored according to crosswalk approach, the EQ-5D-3L index appears to be more responsive in stroke population
Evaluating Equivalency Between Response Systems
Vol. 45, No. 9, pp. 812–819. In the article cited above, Table 3 showing EQ-5D United Kingdom utility weights (coefficients) for pain/discomfort should be switched with anxiety/depression weights in columns 4 and 5. A corrected Table 3 appears below.TABLE 3: Transformation of United Kingdom and Dutch EQ-5D Algorithms to 5 L System
Interim Scoring for the EQ-5D-5L
Measurement properties of the EQ-5D-5L compared to the EQ-5D-3L across eight patient groups
The EQ-5D-5L appears to be a valid extension of the 3-level system which improves upon the measurement properties, reducing the ceiling while improving discriminatory power and establishing convergent and known-groups validity

Evaluating the discriminatory power of EQ-5D, HUI2 and HUI3 in a US general population survey using Shannon’s indices
Performance in terms of absolute and relative informativity of the common dimensions of the three instruments varies over dimensions. Several dimensions are suboptimal: Pain/Discomfort (EQ-5D) seems too crude with only 3 levels, and the level descriptions of Ambulation (HUI3) and Self-Care (HUI2) could be improved. In absence of a formal measure, Shannon's indices provide useful measures for assessing discriminatory power of utility instruments
Evaluating Equivalency Between Response Systems
BACKGROUND: Expansion of the EQ-5D health state classifier to 5 levels (EQ-5D-5L) has been proposed to improve discriminative and evaluative properties, but current preference-based algorithms were developed for a 3-level (EQ-5D-3L) structure. The objectives were to examine equivalency of meaning between 3L and 5L response systems, and to psychometrically derive a system of weights that facilitate conversion of 3L preference-based algorithms to a…
Quantification of the level descriptors for the standard EQ-5D three-level system and a five-level version according to two methods
The level descriptors have similar distributions across comparable dimensions within each system, but the pattern differs between 3L and 5L. This methodological study provides evidence of increased descriptive power and a broadened measurement continuum that encourages the further development of an official five-level EQ-5D
