The mental health impact of the coronavirus disease 2019 (COVID-19) pandemic on PK–12 youth is likely an urgent and enduring concern, yet research on this topic is still emerging. To synthesize current knowledge, the researchers conducted a systematic review of empirical studies exploring the mental health impacts of COVID-19. Five themes emerged across 104 included studies: (a) the pandemic proved widely disruptive to PK–12 youth; (b) there was a clear connection between the mental health of caregivers (e.g., parents) and children; (c) the pandemic broadly increased levels of stress, anxiety, and depression in PK–12 youth; (d) students were particularly affected on the basis of age, gender, race/ethnicity, socioeconomic status, and previous mental health or disability diagnosis; and (e) youth demonstrated negative and positive coping strategies and even saw some positive mental health outcomes during the pandemic. Implications for research, practice, and policy are discussed.

2019 年冠状病毒病 (COVID-19) 大流行对 PK-12 青年的心理健康影响可能是一个紧迫而持久的问题，但有关该主题的研究仍在不断涌现。为了综合现有知识，研究人员对探索 COVID-19 对心理健康影响的实证研究进行了系统回顾。104 项研究中出现了五个主题：(a) 大流行证明对 PK-12 青年具有广泛的破坏性；(b) 看护者（例如父母）的心理健康与儿童之间存在明显的联系；(c) 大流行广泛增加了 PK-12 青年的压力、焦虑和抑郁程度；(d) 学生因年龄、性别、种族/族裔、社会经济地位和先前的心理健康或残疾诊断而受到特别影响；(e) 青年表现出消极和积极的应对策略，甚至在大流行期间看到了一些积极的心理健康成果。讨论了对研究、实践和政策的影响。
