Student mental health during Summer 2022 research experiences for undergraduates (REUs): Mentorship, remote engagement, and COVID-19.

We examined how mentorship, remote participation, and COVID-19 challenges were associated with the mental health of college students participating in summer research programs. : Participants were students participating in 78 National Science Foundation (NSF) Research Experiences for Undergraduate (REU) Sites during Summer 2022 ( = 516 students). : We used multivariable generalized estimating equations that account for clustering by REU Site. : Students with more competent mentors had reduced depression severity. Students who spent ≥25% of their time doing remote research or ≥25% of their time in remote meetings and workshops had greater depression severity. Remote research was also associated with anxiety severity. Having a COVID-19 challenge that impacted students' research experience was associated with increases in depression and anxiety severity. : Results suggest potential interventions: implement strategies to boost mentor competency and scaffold a support system into summer research programs to enhance student wellbeing. Additional research on remote engagement is needed.
