EQ-5D-Y (Youth) | About
The child-friendly EQ-5D version (EQ-5D-Y) was introduced by the EuroQol Group in 2009 as a more comprehensible instrument suitable for children and adolescents. The EQ-5D-Y is based on the EQ-5D-3L and essentially consists of 2 pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS).
The EQ-5D-Y descriptive system comprises the following five dimensions: mobility, looking after myself, doing usual activities, having pain or discomfort and feeling worried, sad or unhappy. Each dimension has 3 levels: no problems, some problems and a lot of problems. The younger patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the younger patient’s health state.
The EQ VAS records the younger patient’s self-rated health on a vertical visual analogue scale where the endpoints are labelled “The best health you can imagine” and “The worst health you can imagine”. The VAS can be used as a quantitative measure of health outcome that reflects the younger patient’s own judgement.
Main differences between the EQ-5D-Y and the EQ-5D-3L
The EQ-5D-Y differs from the EQ-5D-3L on the following points:
- The wording in the five dimensions was changed to be more suitable for children and adolescents.
- The most severe label for the mobility dimension was changed from “confined to bed” to “a lot of problems walking about” to increase the applicability and sensitivity of the mobility dimension.
- The instructions for the EQ VAS task were simplified, making the task easier to complete and to score.
EQ-5D-Y is available in more than 40 languages and in various modes of administration.
