Objective: Depression and anxiety have been identified as growing concerns for many populations in the United States, including young adults. We investigated how internalizing symptoms may have changed throughout the COVID-19 pandemic among students transitioning to college. Participants: Participants were incoming undergraduates in Fall 2020, 2021, and 2022 at Northeastern Universities (N=263). Methods: Participants completed self-reports of mood, repetitive thinking, and social satisfaction within two weeks of beginning their first college semester. Results: Depression and anxiety symptoms appear to differ by year, such that both have increased over time. These results seem to be co-occurring with an increase in repetitive negative thinking -- a known predictor of depression and anxiety. Conclusions: These preliminary results suggest that mental health concerns in young adults may be worsening despite the resumption of in-person activities post-initial pandemic onset. This highlights the need to monitor and intervene on mental health in students transitioning to college.
