Background: Interpersonal violence against children and adolescents can affect their mental health and functioning in the long term. To reduce mental health problems in children and adolescents, school-based mental health interventions have been shown to be beneficial. A review of school-based interventions designed to mitigate posttraumatic symptoms after interpersonal violence is lacking to date. Methods: We searched for original studies published in English or German until November 2019 in 6 electronic databases. Supplementary search strategies to reduce publication bias were implemented. Peer-reviewed original studies assessing school-based interventions for children and adolescents under the age of 21 after interpersonal violence were included. Relevant data was extracted, synthesised and assessed qualitatively. The methodological quality of included studies was assessed. Results: Of 5,021 unduplicated publications, 15 studies met eligibility criteria. The included studies were almost exclusively conducted in the USA; over half utilised a randomised-controlled design. Studies mainly focussed on Posttraumatic Stress Disorder (PTSD) or depression. In all studies, implemented interventions partially or fully mitigated posttraumatic symptoms. Nine school-based interventions, five of which were based on cognitive behavioural therapy (CBT), were identified. School staff were often involved in intervention implementation besides mental health professionals. Conclusions: School-based interventions can be beneficial to reduce mental health problems in children and adolescents after interpersonal violence. Trained school staff aided by mental health professionals can implement trauma-informed practices at school. While school-based interventions may be a feasible way to provide children and adolescents with accessible mental health care, further research on school-based trauma interventions outside the USA is necessary.

背景：针对儿童和青少年的人际暴力会长期影响他们的心理健康和功能。为了减少儿童和青少年的心理健康问题，以学校为基础的心理健康干预已被证明是有益的。迄今为止，缺乏对旨在减轻人际暴力后创伤后症状的基于学校的干预措施的审查。方法：我们在 6 个电子数据库中搜索了截至 2019 年 11 月以英语或德语发表的原始研究。实施了减少发表偏倚的补充搜索策略。同行评议的原始研究评估了人际暴力后 21 岁以下儿童和青少年的学校干预措施。提取、综合和定性评估相关数据。评估纳入研究的方法学质量。结果：在 5,021 篇不重复的出版物中，15 项研究符合资格标准。纳入的研究几乎全部在美国进行；超过一半的人采用了随机对照设计。研究主要集中在创伤后应激障碍（PTSD）或抑郁症。在所有研究中，实施的干预措施部分或完全减轻了创伤后症状。确定了九项基于学校的干预措施，其中五项基于认知行为疗法（CBT）。除心理健康专业人员外，学校工作人员还经常参与干预实施。结论：基于学校的干预有助于减少人际暴力后儿童和青少年的心理健康问题。在心理健康专业人员的帮助下，训练有素的学校工作人员可以在学校实施创伤知情实践。虽然以学校为基础的干预措施可能是为儿童和青少年提供可获得的心理保健的可行方式，但有必要对美国以外的以学校为基础的创伤干预措施进行进一步研究。
