摘要: Purpose: The advent of online task distribution has opened a new avenue for efficiently gathering community perspectives needed utility estimation. Methodological consensus estimating pediatric utilities is lacking, with disagreement over whom to sample, what perspective use (patient vs parent) and whether instrument induced anchoring bias significant. We evaluated methodological factors potentially impact estimates vesicoureteral reflux.Materials Methods: Cross-sectional surveys using time trade-off were conducted via the Amazon Mechanical Turk® (https://www.mturk.com) interface. Respondents randomized answer questions from child, parent or dyad on reflux health state 1 3 “warm-up” scenarios (paralysis, common cold, none) before scenario. Utility potential predictors fitted generalized linear model determine most impacted utilit...
