Survey Fraud and the Integrity of Web-Based Survey Research

Abstract: Compared to traditional paper surveys, online surveys offer a convenient, efficient, and socially distant way to conduct human subjects research. The popularity of online research has grown in recent decades. However, without proper precautions, false respondents pose a serious risk to data integrity. In this paper, we describe our research team’s own encounter with survey fraud, steps taken to preserve the integrity of our study, and implications for future public health research.

“…Fraudulent surveys include duplicate responses from the same participant using different email addresses, providing response patterns, or reaccessing the survey with false responses after being deemed ineligible in the first attempt. To minimize these risks, we implemented a series of combined red flags based on previous literature [ 39 , 40 , 48 , 49 ] and our own team’s experience. Once data collection for the baseline (T2) survey was completed, we downloaded all the data from Qualtrics.…”

“…As part of routine, monthly quality control procedures, we cross-checked all enrolled participants with WIC agencies to confirm WIC participation (a criteria for inclusion). We identified numerous ineligible participants likely created by bots hacking the survey, which the authors describe in detail elsewhere [ 15 ]; all false survey responses ( n = 228) were identified and removed.…”

“…In other instances, researchers who described experiencing an overwhelming number of fraudulent respondents proposed several data-based screening tools, which may be used to flag respondents in existing data (Griffin et al, 2022; Pozzar et al, 2020; Xu et al, 2022). Common data-based screening tools described in the literature include (a) evaluating qualitative responses for duplicate phrasing or illogical answers, (b) identifying discrepancies to verifiable items, and (c) identifying identical response patterns to quantitative surveys (Griffin et al, 2022; Levi et al, 2021; Pozzar et al, 2020; Simone, 2019). Given that bots have the propensity to improve their capacity to pass many question- and data-based screening tools due to algorithmic learning, we considered using common behavioral and cognitive psychological tasks (e.g., anagrams) as an avenue to examine the efficacy of task-based bot screening tools.…”

“…Notably, most bot detection research has been conducted in response to an unexpected encounter with bots, and thus no known study has used experimental methods to investigate the prospective effectiveness of distinct bot screening tools. All known existing contributions to this line of work are case studies that detail how the authors mitigated threats to data integrity when bots attacked their online surveys (Griffin et al, 2022; Levi et al, 2021; Pozzar et al, 2020; Simone, 2019; Storozuk et al, 2020). By using an experimental approach that replicates the features of data collection in extant case studies that report bot intrusions (i.e., health- and social-focused research, posting survey links on social media) and only varying the incentive amount offered, the present study may uncover how incentives affect the proportion of bots detected in online survey research and how incentives affect the effectiveness of bot screening tools.…”
