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.

摘要 大约一半的性侵犯涉及犯罪者，受害者或两者的酒精消费。自我- 对受害者和肇事者进行的调查报告提供了有关酒精作用的宝贵信息 在性侵犯;然而，因果关系不能建立从相关的设计。当参与者 在实验室研究中随机分配到饮酒条件下，可以得出关于 急性饮酒对行为的影响。实验者面临的主要挑战是 性侵犯的代理人，有很强的结构效度和实验现实主义。虚拟现实 环境（VRE）为参与者提供了沉浸在模拟环境中的机会。 因此，参与者的行为方式和做出的选择与他们的行为密切相关。 实验室外的行为。拟议研究的目标是建立在有希望的发现， PI最近的R21赠款（AA020876）开发了一种约会模拟作为一种新的实验范式， 研究酒精在男性对女性实施熟人性侵犯中的作用。的 所提出的研究的第一个具体目标涉及根据以下方面的见解增强VR约会模拟： 我们的经验发现和新技术的发展。更新后的模拟将是三维的， 参与者佩戴头戴式显示器，使他们与女性一起沉浸在虚拟世界中， 伴侣.将在焦点小组和与男性和女性的认知访谈中制定和评估变化。 女性参与者最大限度地提高生态效益。第二个具体目标涉及系统评估 在虚拟现实环境中操纵的情境线索的影响， “当下”的认知和感觉被假设为增加性行为的可能性 男性的性攻击倾向。第三个具体目标涉及审查 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（酒精条件：清醒与醉酒;目标BrAC = 0.08）× 2（高或低水平的提示， 影响参与者对女性性兴趣的看法）X2（影响女性性兴趣的高或低水平线索） 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 犯罪将在一个单独的会议进行评估，预计将与酒精和线索相互作用 条件，这样的醉酒男子谁是倾向于性侵犯（例如，更高预先存在水平 敌对的男性气质），并暴露于性兴趣和权利/愤怒的线索被假设为是最 很可能有性侵犯倾向未来的研究可以改变模拟的各个方面，以增加普遍性 不同的人群。申请人的长期目标是确定可改变的风险和保护因素， 可用于制定循证预防和治疗干预措施，以减少性暴力。
