Comparative Study
Validation and comparison of the psychometric properties of the EQ-5D-3L and EQ-5D-5L instruments in Greece.
To validate and compare the psychometric properties of the EQ-5D-3L with the EQ-5D-5L classification systems in Greece. ⋯ Both EQ-5D versions demonstrated good construct validity and had consistent redistribution. The EQ-5D-5L system may be preferable to the EQ-5D-3L, as it exhibited superior performance in terms of lower ceiling effects, higher absolute and relative informativity, and improved convergent and known-groups validity efficiency.
