Designing for Decisions: Practical Strategies to Improve DCE Response Quality

Speaker:

Assoc Prof Alison Pearce leads the Health Economics team at the University of Sydney Daffodil Centre – a partnership with the Cancer Council NSW. She uses patient preference studies to improve cancer care by providing relevant, reliable information for decision making.

Dr. Amber Salisbury works as a Health Economics Researcher at the University of Manchester. Her current research centres on patient preference studies that aim to support the implementation of cancer screening within the UK.

Join Associate Professor Alison Pearce (University of Sydney Daffodil Centre) and Dr Amber Salisbury (University of Manchester) as they share findings from a series of studies involving almost 4,000 participants across six discrete choice experiments (DCEs). As DCEs become increasingly popular in health research, concerns remain about participant engagement, comprehension, and the growing challenge of bot responses. This webinar will explore practical strategies commonly used to improve response quality—including encouraging messages, instructional videos, and hidden bot-detection questions—and examine whether they actually make a difference. Drawing on empirical evidence, Alison and Amber will discuss what worked, what didn’t, and where researchers should focus their efforts to maximize the quality and reliability of DCE data. This session will be of interest to health economists, preference researchers, implementation scientists, and anyone designing or analyzing DCEs.
