Objectives: The study aimed to assess the reliability and validity of EQ-5D-5L-Y and to compare the performance of EQ-5D-5L-Y with EQ-5D-3L-Y in children and adolescents. Methods: The Spanish versions of the 3L and 5L of EQ-5D for youths, were administered to children and adolescents from the general population. Feasibility and reliability were determined for the EQ-5D-5L-Y. The EQ-5D-5L-Y and EQ-5D-3L-Y were evaluated in terms of ceiling effects, informativity, and correlations with other generic measurements of health-related quality of life. Results: A total of 714 healthy children and adolescents (10.7 ± 2.1 years old) from the general population participated in the study. Most of the sample reported full health status. The feasibility and reliability for the EQ-5D-5L-Y were acceptable, but the questionnaire showed a low convergent validity. Absolute informativity (Shannon index) showed a slight increase in all dimensions of the 5L compared with the 3L; nevertheless, there were only statistically significant differences between 5L and 3L in the dimension “feeling worried, sad, or unhappy” and also on the overall system. Relative informativity (Shannon evenness index) showed a decrease in the 5L compared with 3L for all dimensions, except for “looking after myself.” Correlations with other health measurements, in both 3L and 5L, showed similar results to those observed in the international EQ-5D-3L-Y validation study. Conclusion: The results show that EQ-5D-5L-Y is feasible, consistent, and reliable, but there are minor differences in the ceiling effect and informativity between the EQ-5D-5L-Y and EQ-5D-3L-Y versions in the general population.
