Many surveys, including health preference studies, collect data through web-based instruments. The risk of online data collection fraud is growing, and researchers need to understand the threat and ways to reduce risks to data collection. The workshop will identify commonly encountered sources of fraudulent responses (eg, bots, coordinated attacks by individuals) and the risks of data collection fraud for different online recruitment methods (eg, panels, social media, members of organizations).
We will discuss recruitment strategies and metrics to identify and minimize the risk of fraudulent respondents and share ideas for designing preference surveys that reduce fraud risk. We will also suggest methods for real-time fraud screening, as well as analysis algorithms that identify, and could help likely fraudulent responses post-data collection. We will present examples from several case studies from health preference assessment surveys covering how the fraud occurred, how it was discovered, statistical techniques to identify patterns in discrete-choice data that might indicate fraudulent responses, and lessons learned. Each speaker will present for approximately 13 minutes, leaving about 20 minutes for discussion.
The specific examples will pertain to health preference surveys, however, anyone who utilizes online data collection for their studies may find the workshop of interest. The workshop will use real-time polling to understand the audience’s experiences with data collection fraud online and the methods used to prevent and identify data collection fraud. We will encourage audience members to share their own strategies, learnings, and challenges.
- Identify situations where data collection fraud might be a problem in online survey research
- Learn how to design survey instruments and data collection strategies to reduce the risk of fraudulent respondents, with examples from health preference studies
- Learn techniques to help identify fraudulent data from health preferences surveys and other types of surveys
