Background. Logical inconsistency for health states preferences occurs when one logically worse health state, in terms of quality of life, is ranked higher than a logically better health state. Objective. This study explores the presence of inconsistent responses for the EQ-5D health states valuations in a Brazilian population survey. It compares the level of inconsistency in 3 preference-based methods: ranking, visual analog scale (VAS), and time tradeoff (TTO). The influence of EQ-5D health…

Estimating an EQ-5D-5L Value Set for China.
Similar responses to EQ-5D-3L by two elicitation methods: visual analogue scale and time trade-off
VAS and TTO can generate similar responses under certain conditions, suggesting that the two valuation methods could be equivalent intrinsically.
Transforming Latent Utilities to Health Utilities: East Does Not Meet West
Results suggest that regional transformation functions could potentially be used to derive health utilities from DCE data, and less variation in the function that transformed latent utilities to health utilities in the western countries than in the eastern countries.

Inconsistencies in TTO and VAS Values for EQ-5D Health States
The aim of this study was to assess the effect of inconsistently valued EQ-5D health states on mean visual analog scale (VAS) and time trade-off (TTO) values.

Canadian Valuation of EQ-5D Health States: Preliminary Value Set and Considerations for Future Valuation Studies
A preference-weight algorithm for Canadian studies that include the EQ-5D is developed, which yields a good fit with observed TTO values, and insights into potential issues for conducting valuation studies in countries as large and diverse as Canada are gained.
Social valuation of EQ-5D health states: the Chilean case.
Valuation of EQ-5D health states in Poland: first TTO-based social value set in Central and Eastern Europe.
This is the first EQ-5D value set based on TTO in Central and Eastern Europe so far and should be recommended for studies in Poland because the values differ considerably from those elicited in Western European countries.
Argentine valuation of the EQ-5D health states.
This study provides an Argentine value set that could be used locally or regionally, with meaningful and significant differences with that of the United States.
Logical inconsistencies in survey respondents' health state valuations -- a methodological challenge for estimating social tariffs.
There is no simple, generalisable 'rule' to guide exclusions and therefore researchers ought to explore the sensitivity of their estimated tariffs to alternative treatments of logically inconsistent responses, and reports equations for two tariffs that arise from contrasting approaches.
