Comparative performance of EQ-5D-5L bolt-ons in China and the Netherlands: results from the EQ-DAPHNIE project.

ABSTRACT:

Purpose

This study compares the psychometric properties of eight EQ-5D-5L bolt-ons in the general populations from two culturally distinct countries: China (CN) and the Netherlands (NL).

Methods

As part of the EQ-DAPHNIE project, cross-sectional online surveys were conducted in 2024 with quota-based samples approximating the adult population from CN and the NL. Participants completed EQ-5D-5L, eight bolt-ons (vision, hearing, breathing, sleep, tiredness, social relationships, self-confidence, and cognition/memory), and sociodemographic and health-related questions. Psychometric assessments included ceiling, convergent/divergent validity, structural validity, known-groups validity, and explanatory power.

Results

The ceiling of the EQ-5D-5L was higher in CN (45%) than N
