There are unique challenges that arise from participating in remote clinical trials. Broadly, findings suggest that participants enrolled in digital intervention trials are more likely to disengage or prematurely dropout than participants in face-to-face trials. Thus, optimizing contact with participants via video-conferencing platforms to build rapport and encourage commitment to the study is critical. Still, challenges with video-conferencing visits can pose challenges. Some of these challenges include a lack of clarity about study requirements, difficulties demonstrating staff engagement and building rapport, and the technical challenges of using video-conferencing software. These challenges can affect participant retention, study validity, and the willingness of underserved groups to participate in research. In the context of a remote randomized clinical trial evaluating a digital intervention for prenatal insomnia, we discuss strategies used to counteract these challenges, including the use of virtual orientation sessions, and practical recommendations to improve staff engagement with participants. These findings are relevant to research teams conducting remote clinical trials, especially those seeking to recruit and retain participants from populations currently and historically underrepresented in research.
