Preventing Sexual Aggression among University

项目摘要

Sexual aggression, defined as sexual contact without consent, is a widespread problem among young people, with about one in five women and a lower, yet substantial proportion of men reporting victimization experiences. However, there is a lack of effective, evidence-based prevention programs. The proposed project will develop and evaluate an intervention to prevent sexual aggression perpetration and victimization among university students. By combining an experimental evaluation with a longitudinal design, it is possible not only to assess the efficacy of the intervention but also to evaluate hypotheses about the causal impact of the risk factors targeted by the intervention on the probability of sexual aggression victimization and perpetration. Based on past research on the prevalence of sexual aggression as well as risk factors of perpetration and vulnerability factors of victimization, the program will include first-year students starting university in the academic year 2018/19 and follow them over two follow-up data waves at the end of their first year (+ 8 months) and second year (+ 12 months) of study, covering a total of 20 months. The theory-based intervention centers on changing sexual scripts for consensual sex, as these cognitive representations have been shown to play a decisive role in predicting sexual aggression. Sexual scripts are considered risky to the extent that they contain factors linked to a heightened probability of sexual aggression perpetration and/or victimization. These factors include alcohol use, ambiguous communication pattern, and sexual contacts with casual partners, which inform sexual behavior. In addition, the intervention will target sexuality-related cognitions (sexual self-esteem, acceptance of sexual coercion) and behaviors (sexual assertiveness, use of pornography). These elements will be addressed in six modules presented at weekly intervals in an online format, with a baseline assessment, a post-intervention assessment a week after the intervention, and two follow-ups at the end of the first and second year of study. The intervention group will be compared to a non-treated control group at each wave. Reduced odds of sexual aggression victimization and perpetration in the intervention group are the critical outcome variables. The project adopts a gender-inclusive approach by considering males and females in both victim and perpetrator roles and tailoring the intervention to participants’ gender and sexual experience background (opposite and/or same-sex sexual contacts).

性侵犯被定义为未经同意的性接触，是年轻人中的一个普遍问题，大约五分之一的女性和比例较低但比例较高的男性报告了受害经历。然而，缺乏有效、基于证据的预防措施。拟议的项目将开发和评估预防大学生性侵犯和受害的干预措施，通过将实验评估与纵向设计相结合，不仅可以评估干预措施的有效性，还可以评估假设。关于干预措施所针对的风险因素对性侵犯受害和实施的可能性基于过去对性侵犯发生率以及实施的风险因素和受害脆弱性因素的研究，该计划将包括 2018/19 学年开始大学的一年级学生，并遵循以下原则：他们在第一年（+ 8 个月）和第二年（+ 12 个月）研究结束时进行了两次后续数据波，总共覆盖 20 个月。基于理论的干预以改变性脚本为中心。自愿的性行为，因为这些认知表征已被证明在预测性侵犯方面发挥着决定性作用，因为它们包含与性侵犯和/或受害的惊人可能性相关的因素，这些因素包括酒精。此外，干预措施还将针对与性相关的认知（性自尊、接受性强迫）和行为（性自信、性行为的使用）。这些要素将通过每周以在线形式呈现的六个模块进行讨论，其中包括基线评估、干预后一周的干预后评估以及第一年和第二年末的两次后续行动。干预组将在每一波中与未接受治疗的对照组进行比较，干预组中性侵犯受害和实施的几率降低是该项目采用性别包容的方法，考虑了男性和女性。女性同时扮演受害者和施暴者的角色，并定制对参与者的性别和性经历背景（异性和/或同性性接触）进行干预。
