This meta-analysis quantitatively summarizes the effect of workplace safety training interventions on safety performance antecedents (safety motivation, knowledge, and climate) and safety performance (safety compliance and participation). One hundred unique samples from 90 published reports representing a wide variety of industries were included in this meta-analysis. While we found that safety training improved all the studied outcomes (d statistics ranging from 0.25 for safety participation to 0.87 for safety knowledge), the effect of industry risk-level was not consistent across the outcomes assessed. In high-risk industries (compared to low-risk industries), safety performance saw smaller gains (in line with Homeostasis Theory), but safety climate and motivation saw larger gains after safety training (contrary to the predictions of Homeostasis Theory) compared to low-risk industries.

该元分析定量总结了工作场所安全培训干预措施对安全绩效前因（安全动机、知识和气候）和安全绩效（安全合规和参与）的影响。该元数据包含来自 90 份已发表报告的代表各种行业的一百个独特样本-分析。虽然我们发现安全培训改善了所有研究结果（d 统计量从安全参与的 0.25 到安全知识的 0.87），行业风险水平的影响在评估的结果中并不一致。在高风险行业（与低风险行业相比），安全绩效的收益较小（符合稳态理论），但与低风险行业相比，安全氛围和动机在安全培训后（与稳态理论的预测相反）获得了更大的收益——风险行业。
