I have been scammed in my qualitative research

We have been scammed in our online qualitative study by some fraudulent participants who falsely claimed to be pharmacists or community health workers. These participants were interviewed before we discovered that they were not who they claimed to be.In this commentary, we describe key indicators of potential imposters, such as the number of emails received in a short period of time, emails with similar content and address structure, participants having a keen interest in the reimbursement, camera switched off during the interview, and inconsistency in the participants' responses.We provide recommendations on how to prevent future fraud, such as promoting the study to a closed network or groups on social media, encouraging participants to provide sources that verify their identity, ensuring that the camera is switched on during the entire interview, discouraging the use of artificial intelligence (AI) to answer questions or generate content, unless when AI-based language tools are used to facilitate translation, understanding or communication, providing reimbursements with local vouchers rather than international ones, and where the participants are healthcare professionals, checking their registration number prior to the interview.It is important for Human Research Ethics Committee members to consider genuine measures to assess participant authenticity and reduce the risk of fraudulent participation. Additionally, universities and research institutions should develop guidance to educate researchers in this area. Published protocols, guidelines and checklists for online qualitative studies, and participant information statements and consent forms should be adapted to prevent and address potential fraud. For example, the COREQ checklist should be updated so that researchers report the actions undertaken to prevent and detect fraud and their experiences and actions if there was fraud.Fraud in online research impacts the integrity and quality of online research. Urgent actions are needed to raise awareness of this issue within the research community and prevent further occurrences of scams.
