This pre-registered study evaluated an intervention designed to reduce sexual aggression perpetration and victimization by changing risky scripts for consensual sexual interactions and corresponding risky sexual behavior, and by improving sexual self-esteem, refusal assertiveness, and initiation assertiveness. In a four-wave longitudinal study covering 23 months, 1181 university students in Germany (762 female) were randomly assigned to an intervention and a no-intervention control group. The intervention group completed six weekly modules addressing the targeted theory-based risk and vulnerability factors of sexual aggression perpetration and victimization. Controlling for baseline levels (T1), the intervention group showed less risky sexual scripts one week post-intervention (T2), which predicted less risky sexual behavior nine months later (T3), which predicted lower odds of sexual aggression perpetration and victimization 12 months later (T4). No direct intervention effects on rates of sexual aggression perpetration and victimization at T3 and T4 were found. No indirect intervention effect on sexual aggression was found via sexual self-esteem and sexual assertiveness. However, sexual self-esteem at T2, which was higher in the intervention group, predicted lower odds of sexual aggression victimization at T3 via higher initiation assertiveness at T3. Implications for reducing sexual aggression and conceptualizing risk and vulnerability factors of sexual aggression are discussed.
这项预先注册的研究评估了一项干预措施，该措施旨在通过改变对双方同意的性互动的风险脚本和相应的风险性行为，以及通过提高性自尊、拒绝自信和主动自信，来减少性侵犯的实施和受害。在一项为期 23 个月的四波纵向研究中，德国的 1181 名大学生（762 名女性）被随机分配到干预组和无干预对照组。干预组完成了六个每周模块，针对性侵犯实施和受害的有针对性的基于理论的风险和脆弱性因素。在控制基线水平（T1）的情况下，干预组在干预后一周表现出较少的风险性行为脚本（T2），这预测了九个月后更具风险的性行为（T3），这预测了 12 个月后性侵犯实施和受害的几率较低（T4）。在 T3 和 T4 时，没有发现对性侵犯实施率的直接干预效果。没有通过性自尊和性自信发现对性侵犯的间接干预效果。然而，在干预组中更高的 T2 性自尊通过更高的 T3 启动自信预测了 T3 时性侵犯受害的几率降低。讨论了减少性侵犯和概念化性侵犯的风险和脆弱性因素的含义。
