Journal ArticleDOI
Development and preliminary testing of the new five-level version of EQ-5D (EQ-5D-5L)
Michael Herdman,Claire Gudex,Andrew Lloyd,Mathieu F. Janssen,Paul Kind,David Parkin,Gouke J. Bonsel,Xavier Badia +7 more
TL;DR: A 5-level version of the EQ-5D has been developed by the EuroQol Group and further testing is required to determine whether the new version improves sensitivity and reduces ceiling effects.
Journal ArticleDOI
Interim Scoring for the EQ-5D-5L: Mapping the EQ-5D-5L to EQ-5D-3L Value Sets
Ben A. van Hout,Mathieu F. Janssen,You-Shan Feng,Thomas Kohlmann,Jan J. Busschbach,Dominik Golicki,Andrew B. Lloyd,Luciana Scalone,Paul Kind,A. Simon Pickard +9 more
TL;DR: The nonparametric model was preferred for its simplicity while performing similarly to the other models, and being independent of the value set that is used, it can be applied to transform any EQ-5D-3L value set into EQ- 5D-5L index values.
Journal ArticleDOI
Measurement properties of the EQ-5D-5L compared to the EQ-5D-3L across eight patient groups: A multi-country study
Mathieu F. Janssen,A. Simon Pickard,Dominik Golicki,Claire Gudex,Maciej Niewada,Luciana Scalone,P. Swinburn,Jan J. V. Busschbach +7 more
TL;DR: 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.
Journal ArticleDOI
Comparing the standard EQ-5D three-level system with a five-level version.
TL;DR: The EQ-5D five-level version appears a valid and reliable extension of the three-level system and is particularly useful for describing mild health problems and monitoring population health.
Journal ArticleDOI
Is EQ-5D-5L Better Than EQ-5D-3L? A Head-to-Head Comparison of Descriptive Systems and Value Sets from Seven Countries
TL;DR: 5L provides more precise measurement at individual and group levels, both in terms of descriptive system data and utilities, which is likely to be generalisable to longitudinal studies, including economic evaluation, clinical and public health studies.
