Findings
depression, behavioral difficulties
In this cohort study of 7250 UK students not exposed (12 schools; n = 864 students) and exposed (72 schools; n = 6386 students) to the pandemic during assessment, greater risk for depression; social, emotional, and behavioral difficulties; and deteriorations in mental well-being were associated with the pandemic. Risk and resilience were associated with individual, home, friendship, and school characteristics.
