Violence in the workplace represents a pressing social problem, drawing attention to the need for both public and private prevention interventions. Workplace violence and workplace violence prevention serve as a crucial topic globally, given the context of violence and victimization in the workplace across a range of industries, and in the context of the Covid-19 pandemic. The objective of this article is to carry out a systematic review and meta-analysis of the effects of the full range of approaches to prevent workplace violence. Following PRISMA guidelines, this review uses rigorous criteria for the inclusion of studies, comprehensive search strategies to identify eligible studies, and a detailed protocol for coding study characteristics. Meta-analytic techniques are used to assess the impact of prevention interventions (at the employee- and organizational-levels) on workplace violence. Ten studies met the inclusion criteria. The weighted mean effect sizes for employee and organizational-level studies were positive and moderate, yet non-significant: d = 0.50 (95% CI = −0.05, 1.06) and d = 0.22 (95% CI = −0.62, 1.07), respectively. Variability of intervention modalities, the promising nature of some prevention interventions, and the need for consideration of a broader range of measures of workplace violence offer some directions for future research to help inform policy and practice.

工作场所的暴力是一个紧迫的社会问题，引起人们对公共和私人预防干预的必要性的关注。鉴于一系列行业的工作场所暴力和受害情况以及 Covid-19 大流行的背景，工作场所暴力和预防工作场所暴力是全球的一个重要话题。本文的目的是对预防工作场所暴力的各种方法的效果进行系统回顾和荟萃分析。遵循 PRISMA 指南，本综述使用严格的研究纳入标准、全面的搜索策略来识别符合条件的研究，以及对研究特征进行编码的详细协议。元分析技术用于评估预防干预（在员工和组织层面）对工作场所暴力的影响。十项研究符合纳入标准。员工和组织层面研究的加权平均效应量为正且中等，但不显着：d  = 0.50 (95% CI = -0.05, 1.06) 和d  = 0.22 (95% CI = -0.62, 1.07)。干预方式的可变性、一些预防干预措施的前景以及考虑更广泛的工作场所暴力措施的需要为未来的研究提供了一些方向，以帮助为政策和实践提供信息。
