Abstract Approximately half of all sexual assaults involve alcohol consumption by the perpetrator, victim, or both. Self- report surveys conducted with victims and perpetrators have provided valuable information about alcohol's role in sexual assault; however, causality cannot be established from correlational designs. When participants are randomly assigned to drink conditions in laboratory studies, causal conclusions can be made regarding the effects of acute alcohol consumption on behavior. The major challenge for experimentalists is to develop proxies for sexual assault that have strong construct validity and experimental realism. Virtual reality environments (VRE) provide the opportunity for participants to become immersed in the simulated environment; thus, participants are expected to behave in ways and to make choices that closely relate to their behavior outside the laboratory. The goal of the proposed research is to build on the promising findings from the PIs recent R21 grant (AA020876) that developed a dating simulation as a new experimental paradigm for examining alcohol's role in acquaintance sexual assault perpetration committed by men against women. The first specific aim of the proposed research involves enhancing the VR dating simulation based on insights from our empirical findings and new technological developments. The updated simulation will be 3-dimensional, with participants wearing head mounted displays that immerse them in the virtual world with their female companion. Changes will be developed and evaluated in focus groups and cognitive interviews with male and female participants to maximize ecological validity. The second specific aim involves systematically evaluating the impact of situational cues manipulated within the virtual reality environment which are expected to evoke the "in the moment" cognitions and feelings that are hypothesized to increase the likelihood of sexual aggression among men predisposed to be sexually aggressive. The third specific aim involves examining the effects of acute alcohol consumption on men's sexually aggressive responses in the virtual reality simulation. Based on the findings from the studies associated with Specific Aim 2, situational factors will be manipulated resulting in a 2 (alcohol condition: sober vs. intoxicated; target BrAC = .08) X 2 (high or low level of cue that affects participants' perceptions of the woman's sexual interest) X 2 (high or low level of cue that affects participants' sense of entitlement and anger after a refusal) design. Risk factors associated with sexual assault perpetration will be assessed in a separate session and are expected to interact with alcohol and cue conditions, such that intoxicated men who are predisposed to sexual aggression (e.g., high pre-existing levels of hostile masculinity) and exposed to sexual interest and entitlement/anger cues are hypothesized to be most likely to be sexually aggressive. Future studies can alter aspects of the simulation to increase generalizability to different populations. The applicants’ long-term goal is to identify modifiable risk and protective factors that can be used to develop evidence-based prevention and treatment interventions to reduce sexual violence.

抽象的 大约一半的性侵犯涉及犯罪者、受害者或两者的饮酒。 报告对受害者和罪犯进行的调查提供了有关酒精作用的宝贵信息 在性侵犯中；然而，因果关系不能从相关设计中建立。 在实验室研究中随机分配给饮酒条件，可以得出因果结论 急性饮酒对行为的影响对实验者来说主要的挑战是发展。 具有很强的结构有效性和实验现实性的性侵犯代理。 环境（VRE）为参与者提供了沉浸在模拟环境中的机会 因此，人们应该以与其自身密切相关的方式行事并做出选择。 拟议研究的目标是建立在实验室外的有希望的发现的基础上。 PI 最近的 R21 资助（AA020876）开发了约会模拟作为新的实验范式 研究酒精在男性对女性实施熟人性侵犯中的作用。 拟议研究的第一个具体目标是根据以下方面的见解增强 VR 约会模拟 我们的实证研究结果和新技术发展将是 3 维的，具有 参与者佩戴头戴式显示器，与女性一起沉浸在虚拟世界中 将在焦点小组和对男性和同伴的认知访谈中制定和评估变化。 女性参与者的第二个具体目标是系统地评估生态有效性。 在虚拟现实环境中操纵的情景线索的影响预计会引起 有兴趣增加性可能性的“当下”认知和感受 第三个具体目标是检查有性攻击倾向的男性之间的攻击行为。 在虚拟现实模拟中，急性饮酒对男性性攻击反应的影响。 根据与具体目标 2 相关的研究结果，将操纵情境因素 导致 2（酒精状况：清醒与醉酒；目标 BrAC = .08）X 2（高或低水平的提示，表明 影响参与者对女性性兴趣的看法） 参与者的权利感和拒绝后的愤怒）设计与性侵犯相关的风险因素。 犯罪行为将在单独的会议中进行评估，并预计与酒精和提示相互作用 条件，例如容易发生性侵犯的醉酒男性（例如，先前存在的高水平 敌对的男性气质）和暴露于性兴趣和权利/愤怒线索被认为是最重要的 未来的研究可以改变模拟的各个方面以提高普遍性。 申请人的长期目标是确定可改变的风险和保护因素。 可用于制定基于证据的预防和治疗干预措施，以减少性暴力。
