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. In children aged 4-7 years, researchers should consider using the proxy version of EQ-5D-Y-5L (i.e. a version in which a parent or other caregiver provides a rating of the child’s health) or an interviewer-administered version (for a self-rating by the child) . Both of these modes of administration can also 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 deciding which version of the instrument to use, and which mode of administration
