Are the age ranges for use identical between the EQ-5D-Y-5L and EQ-5D-Y-3L?

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 and EQ-5D-Y-3L. Nevertheless, we advise that consideration be given to the schooling system and literacy level of the study population when de deciding which version of the instrument to use, and which mode of administration.
