Few studies have evaluated the effectiveness of sexual assault investigations training using experimental designs. Existing studies have not examined the impact of officers’ levels of impulsivity and education on training effectiveness. Using a Solomon four-group quasi-experimental design to assess pretesting effects, we examined the impact of training, impulsivity, and education on officers’ (N = 432) adherence to rape myths and knowledge of victim reporting behaviors. Ordinary least squares (OLS) models were estimated to examine main effects of training, and moderating effects of impulsivity and education on training for our outcome variables. Results demonstrated that training, impulsivity, and education predicted improvements in attitudinal and cognitive outcomes. However, neither impulsivity nor education moderated—or changed—the effectiveness of training. In addition, training effects held over time, and we did not detect evidence of pretesting effects. Findings from this study improve our understanding of police sexual assault investigations training and provide methodological advancements for police training evaluations.

很少有研究使用实验设计评估性侵犯调查培训的有效性。现有的研究并没有研究人员的冲动程度和教育水平对培训效果的影响。使用所罗门四组准实验设计来评估预测试效果，我们检查了培训、冲动和教育对军官（N= 432）坚持强奸神话和受害者报告行为的知识。估计普通最小二乘 (OLS) 模型来检查训练的主要影响，以及冲动性和教育对我们结果变量的训练的调节作用。结果表明，培训、冲动和教育可以预测态度和认知结果的改善。然而，冲动性和教育都没有缓和或改变培训的有效性。此外，训练效果随着时间的推移而保持，我们没有检测到预测试效果的证据。这项研究的结果提高了我们对警察性侵犯调查培训的理解，并为警察培训评估提供了方法上的进步。
