FAQS | EQ-5D-Y-5L

A mapping study has been commissioned the results of which will allow EQ-5D-Y-5L outcomes to be mapped to existing EQ-5D-Y-3L value sets.

At present, value sets for the EQ-5D-Y-5L are not available. The use of adult EQ-5D-5L value sets to generate EQ-5D values for EQ-5D-Y-5L health states is not recommended. The EQ-5D-5L and EQ-5D-Y-5L descriptive systems differ somewhat and preferences for child health may differ from preferences for adult health, which means that a value set for…

All EQ instruments, including the EQ-5D-Y-5L are copyrighted. Without the prior written consent of the EuroQol Office, it is not permitted to alter, amend, convert, translate, publish or make available in whatever way (digital, hard-copy etc.) the EQ-5D-Y-5L and related proprietary materials.

A considerable number of studies have shown that the EQ-5D-Y-5L is a psychometrically sound instrument which performs at least as well as the EQ-5D-Y-3L, and sometimes better. It has been approved for use by the EuroQol Research Foundation after a long period of development and testing which is described in several publications. Of course, researchers…

Deciding whether to use the EQ-5D-Y-3L or the EQ-5D-Y-5L in any given context depends on many factors, including a study’s characteristics and aims, and the study population. The EQ-5D-Y-3L may be more appropriate in some instances, for example in younger populations, those with low literacy, or where interviewer-administration is required, as it is likely somewhat…

It is currently recommended to use the self-complete EQ-5D-Y-5L in children aged 8-15 years, i.e. the children should complete the questionnaire themselves. Proxy (parent or caregiver) versions are the preferred mode of administration for children aged 4-7 years and can be used in older children if needed. These recommendations are therefore identical for the EQ-5D-Y-5L…

The EQ-5D-Y-3L and EQ-5D-Y-5L include the same dimensions (Mobility, Looking after myself, Doing Usual Activities, Having Pain or Discomfort, Feeling Worried, Sad or Unhappy) but the EQ-5D-Y-5L has five response options (or levels of severity) per dimension compared to the EQ-5D-Y-3L’s three levels. The level structure of the EQ-5D-Y-5L and the adult EQ-5D-5L are quite…

Translation timelines are based on multiple factors (the language, availability of source files, dependencies on other projects etc.). However, given that language versions of EuroQol instruments are produced following a very rigorous translation process, we generally operate with a default timeline of 4/5 months for new language versions.

A number of EQ-5D-Y-5L paper self-complete and digital language versions are available, with more in development. Other modes of administration (proxy versions, interviewer-administered versions, etc) will be available for some of those country/language pairs, and more will be added on an on-going basis. Please check on the EuroQol website  for the latest list of available…

The psychometric properties of the EQ-5D-Y-5L have been published in 18 studies to date.1 Most of these studies have compared the performance of the EQ-5D-Y-5L to the EQ-5D-Y-3L. Noteworthy results include reduced ceiling effects, and evidence for improved construct validity and responsiveness on the EQ-5D-Y-5L compared to the EQ-5D-Y-3L in some populations and conditions. The…
