BACKGROUND
The shift towards online recruitment methods, accelerated by the COVID-19 pandemic, has brought to the forefront the growing concern of encountering fraudulent participants in healthcare research. The increasing prevalence of this issue poses a serious threat to the reliability and integrity of research data and subsequent findings.
OBJECTIVE
This study aimed to explore the experiences of healthcare researchers (HCRs) who have encountered fraudulent participants while using online recruitment methods and platforms. The primary objective was to gain insights into how researchers detect and mitigate fraudulent behavior in their work and provide prevention recommendations.
METHODS
A multimethod sequential design was employed for this pilot study, comprising a quantitative arm involving an online survey, followed by a qualitative arm featuring semi-structured interviews. The qualitative description approach framed the qualitative arm of the study. Sample size determination was based on information power and data redundancy, with content analysis used to analyze open-ended survey questions and interview data.
RESULTS
A total of 37 HCRs participated with 13 of them engaging in qualitative interviews. Online platforms such as Facebook, email, Twitter, and online newsletters were the most used methods for recruitment. 84% of fraudulent participation occurred in studies that mentioned incentives in their recruitment communications, with 71% of HCRs offering physical or electronic gift cards as incentives. Researchers identified several indicators of suspicious behavior, including email surges, discrepancies in contact or personal information, geographical inconsistencies, and suspicious responses to survey questions. HCRs emphasized the need for a comprehensive screening protocol that extends beyond eligibility checks and is seamlessly integrated into the study protocol, grant applications, and Research Ethics Board (REB) submissions.
CONCLUSIONS
This study sheds light on the intricate and pervasive problem of fraudulent participation in healthcare research using online recruitment methods. The findings underscore the importance of vigilance and proactivity among HCRs in identifying, preventing, and addressing fraudulent behavior. To effectively tackle this challenge, researchers are encouraged to develop a comprehensive prevention strategy and establish a community of practice, facilitating real-time access to solutions, support, and the promotion of ethical research practices. This collaborative approach will enable researchers to effectively address the issue of fraudulent participation, ensuring the conduct of high-quality and ethically sound research in the digital age.
