EQ-VT v2 (EuroQol Valuation Technology Protocol, Version 2)
EQ-VT v2 is a standardized protocol used to collect data on how people value different health states described by the EQ-5D-5L questionnaire. It helps generate quality-of-life weights used in health economic evaluations.
At a glance
Use when
Developing country-specific EQ-5D-5L value sets; conducting multinational valuation studies; improving comparability of health state utilities
Avoid when
Rapid or low-resource valuation is needed without capacity for complex survey design; when non-preference-based measures are sufficient
Inputs
Health state descriptions using EQ-5D-5L dimensions and levels; representative population samples; time trade-off and VAS responses
Outputs
Country-specific or pooled EQ-5D-5L value sets; utility scores for health states; methodological guidance for valuation studies
How it works
The EQ-VT v2 (EuroQol Valuation Technology Protocol, Version 2) provides a standardized methodology for conducting valuation studies of EQ-5D-5L health states using time trade-off (TTO) and visual analog scale (VAS) methods. It includes detailed guidance on sampling, survey design, data collection procedures, and modeling approaches to derive value sets for use in cost-utility analyses. Version 2.1 builds on lessons from earlier studies to improve consistency, validity, and cross-country comparability.
- HTA domains
- Patient and Social Aspects
- Categories
- HRQoL
- Assumptions
- Respondents can understand and consistently value hypothetical health states; TTO and VAS methods elicit valid preferences; population samples are representative
- Strengths
- Standardized approach enables cross-national comparisons; improved reliability over earlier versions; supports generation of preference-based quality-adjusted life year (QALY) metrics
- Limitations
- Valuation of hypothetical states may not reflect real-world experience; cultural and linguistic differences may affect responses; complex modeling required to derive value sets
- Also known as
- EQ-5D-5L Valuation Protocol v2, EQ-VT 2.1, EuroQol Valuation Technology Protocol Version 2
