The COVID-19 pandemic had significant impacts on adolescents’ mental health and social interactions; however, little is known about cyber-victimization and mental health concerns from before to during the pandemic. The current study addressed this gap, while also examining how social media use and disagreements with friends during the pandemic were associated with cyber-victimization and mental health outcomes. Participants included 272 youth in the U.S. (56% female; 32% White), surveyed in fall 2019 (M_age = 11.75, SD = 0.68) and spring 2021 (M_age = 13.11, SD = 0.75). Adolescents reported increases in mental health symptoms and decreases in cyber-victimization. Experiencing more cyber-victimization before the pandemic was associated with significant increases in anxiety, depression, and social stress. The results suggest bolstering violence prevention programming in schools to reduce the likelihood of cyber-victimization and associated mental health outcomes.

COVID-19 大流行对青少年的心理健康和社会交往产生了重大影响；然而，人们对大流行之前到期间的网络受害和心理健康问题知之甚少。当前的研究解决了这一差距，同时还研究了大流行期间社交媒体的使用和与朋友的分歧如何与网络受害和心理健康结果相关联。参与者包括 272 名美国青年（56% 为女性；32% 为白人），调查时间为 2019 年秋季（M_年龄 = 11.75，SD = 0.68）和 2021 年春季（M_年龄 = 13.11，标准差 = 0.75）。青少年报告心理健康症状增加，网络受害减少。在大流行之前经历更多的网络受害与焦虑、抑郁和社会压力的显着增加有关。结果建议加强学校的暴力预防计划，以减少网络受害的可能性和相关的心理健康结果。
