Implication

This methodological study compares level descriptors of the EQ-5D 3L and 5L systems, revealing differences in distributions and implications for health measurement.

Key Points

The study aims to compare the quantitative positions of level descriptors between the EQ-5D 3L and 5L systems.
N=82 respondents participated in the study.
Used a direct method with a visual analog scale for nonextreme level descriptors.
Applied an indirect method where respondents scored 15 health scenarios using both 3L and 5L.
Equidistance was rejected for 3L and 5L without transformation but satisfied for 5L after transformation.
Isoformity showed mixed results across 3L and 5L.
Consistency between dimensions was satisfied for both instruments and methods.
