An Empirical Comparison of Discrete Choice Experiment and Best-Worst Scaling to Estimate Stakeholders’ Risk Tolerance for Hip Replacement Surgery

Abstract

Background Previous studies have been inconclusive regarding the validity and reliability of preference elicitation methods. Objective The aim of this study was to compare the metrics obtained from a discrete choice experiment (DCE) and profile-case best-worst scaling (BWS) with respect to hip replacement. Methods We surveyed the general US population of men aged 45 to 65 years, and potentially eligible for hip replacement surgery. The survey included sociodemographic questions, eight DCE questions, and twelve BWS questions. Attributes were the probability of a first and second revision, pain relief, ability to participate in sports and perform daily activities, and length of hospital stay. ..
