PCR172 Communicating Challenging Concepts in Preference Research: Developing and Testing a Discrete Choice Experiment (DCE) Survey in Metastatic Castration-Resistant Prostate Cancer (MCRPC)

Abstract

DCE preference research can assist in revealing patient preferences for defined treatments. However, DCEs that incorporate challenging decision contexts can create a cognitive burden for respondents, especially those from vulnerable populations. Limited comprehension of the survey contents can lead to incorrect respondent interpretations and/or unreliable and inaccurate responses. Using a case study specific to mCRPC, we present the survey design process we used to improve respondents’ comprehension and engagement.
