ObjectiveTo derive a US-based value set for the EQ-5D-5L questionnaire using an international, standardized protocol developed by EuroQol Group.MethodsRespondents from US adult population were quota-sampled on basis of age, sex, ethnicity, and race. Trained interviewers guided participants in completing composite time trade-off (cTTO) discrete choice experiment (DCE) tasks Valuation Technology software routine quality control measures. Data modeled Tobit model cTTO data, mixed logit DCE hybrid that combined data. Model performance was compared logical ordering coefficients, statistical significance, parsimony, theoretical considerations.ResultsOf 1134 respondents, 1062, 1099, 1102 respondents provided useable cTTO, DCE, or responses, respectively, criteria interviewer judgment. Respondent demographic characteristics health status similar to 2015 Census. The selected as preferred generate set. Values ranged −0.573 (55 555) 1 (11 111), with 20% all predicted states scores less than 0 (ie, worse dead).ConclusionsA societal can be used economic evaluations decision making systems. internationally established, develop this recommended Group facilitate cross-country comparisons.
