Discrete choice experiments are an increasingly common method to quantitatively elicit patient preferences for health care. However, these surveys are often complex, and there are concerns about understandability and irrational preferences. Debriefing questions (such as “how difficult was it to understand the choices in this survey?”) are one way to assess participant understanding of a discrete choice experiment, although there is no consensus on the best debriefing questions to ask or how to use the responses in analysis or interpretation. Our current project surveyed health economists and pooled discrete choice experiment data to investigate how debriefing questions are being used and what they can tell us about participants’ understanding of healthcare discrete choice experiments.

Learning objectives:

  • Understand the principals of rational decision making
  • Consider how we can assess understanding and rational decision making in the context of discrete choice experiments
