COVID-19 Impacts Mental Health Outcomes and Ability/Desire to Participate in Research Among Current Research Participants.

OBJECTIVE: This study aimed to examine the impact of coronavirus disease 2019 (COVID-19) on current research participants' mental health outcomes, ability to adhere to behavioral intervention recommendations, and desire to participate in research. METHODS: A quantitative/qualitative cross-sectional survey was used among adults currently enrolled in health-related research (N = 250; 85% women; > 50% currently enrolled in behavioral weight loss intervention). RESULTS: COVID-19 was perceived as a severe threat by most (62.3%). Related to COVID-19, 29.6% of participants reported moderate/severe symptoms of anxiety/depression, and 68.4% reported moderate/severe posttraumatic stress disorder (PTSD) symptomatology, with women more likely to demonstrate moderate/severe anxiety/depression (P = 0.047) and PTSD symptomatology (P = 0.028) relative to men. Those with moderate/severe levels of anxiety/depression (P = 0.0154) and distress (P = 0.0330) were more likely to report a decreased desire to participate in research. Among those in behavioral interventions, individuals perceiving COVID-19 as a moderate/severe threat or experiencing moderate/severe depression or PTSD symptomatology were 4 to 19 times more likely to report that COVID-19 affected their ability to adhere to behavioral recommendations. Qualitative analysis identified four themes describing COVID-19's impact on research experiences: transition, remote intervention delivery, ability to adhere to program goals, and research participation interest. CONCLUSIONS: These data suggest that participants engaged in health-related research perceive COVID-19 as a significant threat, affecting mental health, desire to participate in research, and ability to adhere to intervention recommendations.
