Estimating quality weights for EQ-5D health states with the time trade-off method in South Korea.
OBJECTIVE To estimate quality weights of EQ-5D health states with the time trade-off (TTO) method in the general population of South Korea. METHODS A total of 500 respondents valued 42 hypothetical EQ-5D health states using the TTO and visual analog scale. The quality weights for all EQ-5D health states were estimated by a random effects model and compared with those from studies in other cou...
متن کاملLearning effects in time trade-off based valuation of EQ-5D health states.
OBJECTIVES In EuroQol five-dimensional questionnaire valuation studies, each participant typically assesses more than 10 hypothetical health states by using the time trade-off (TTO) method. We wanted to explore potential learning effects when using the TTO method, that is, whether the valuations were affected by the number of previously rated health states (the sequence number). METHODS We in...
متن کاملLogical inconsistencies in time trade-off valuation of EQ-5D-5L health states: Whose fault is it?
INTRODUCTION Inconsistency in the time trade-off (TTO) task in EQ-5D-5L occurs when a respondent gives a higher value to a logically worse health state, the occurrence of inconsistency compromises the quality of the data. It is not yet clear which factors are associated with individual level inconsistency. Relating inconsistency to the characteristics of the respondent, interviewer, and the int...
متن کاملTime trade-off derived EQ-5D weights for Australia.
BACKGROUND Cost-utility analyses (CUAs) are increasingly common in Australia. The EuroQol five-dimensional (EQ-5D) questionnaire is one of the most widely used generic preference-based instruments for measuring health-related quality of life for the estimation of quality-adjusted life years within a CUA. There is evidence that valuations of health states vary across countries, but Australian we...
متن کاملImproving valuation sampling of EQ-5D health states
BACKGROUND The original valuation exercise which formed the basis of the UK EQ-5D time trade-off social tariff of health states, employed a sampling scheme involving 43 health states. Neither that study, nor other published international valuations studies have used explicit quantifiable criteria to justify the choice of sampled states. New criteria are proposed and methods described to aid res...
