Abstract
This study evaluates changes in bullying before (2009-2019) and after the onset of the novel coronavirus (COVID-19) pandemic (2021-2023) in grades 9-12.
A repeated cross-sectional study analyzed data (2009-2023) from the Youth Risk Behavior Surveillance System. An interrupted time series analysis was conducted to estimate changes in the level of and the trend of bullying.
School bullying (n = 123,952) decreased by 5.14 percentage-points following the pandemic, most pronounced among females (-8.76 percentage-points) and non-Hispanic Whites (-6.82 percentage-points). However, school bullying resurged as the pandemic subsided. While online bullying (n = 107,853) had no notable change during the mid-pandemic period, a stratified analysis revealed a 4.55 percentage-point increase among males and a 3.72 percentage-point decrease among females.
Bullying prevention efforts should move beyond individual-level interventions to address the structural features of school environments. The variations in trends across student populations suggest that targeted strategies that account for subgroup-specific vulnerabilities may be beneficial.
The COVID-19 pandemic was associated with short-term reductions in the level of bullying on school property. Future studies are warranted to further our understanding of the specific reasons for these changes, particularly regarding attitudes and behaviors.
