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或受害者饮酒，或两者兼而有之。自我- 对受害者和肇事者进行的报告调查提供了关于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。当参与者是 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。对于实验者来说，主要的挑战是开发出 具有较强的结构效度和实验现实主义的性侵指标。虚拟现实 环境(VRE)为参与者提供沉浸在模拟环境中的机会 因此，参与者应该以与他们的行为密切相关的方式和做出选择 在实验室外的行为。拟议研究的目标是建立在以下有希望的发现的基础上 PIS最近的R21拨款(AA020876)开发了一个测年模拟作为一种新的实验范例 研究酒精在男性对女性犯下的熟人性侵行为中的作用。这个 拟议研究的第一个具体目标是基于以下方面的见解来增强VR约会模拟 我们的经验发现和新技术发展。更新的模拟将是3维的， 参与者戴着头盔显示器，与他们的女性沉浸在虚拟世界中 同伴。将在焦点小组和与男性和 女性参与者以最大限度地提高生态有效性。第二个具体目标包括系统地评估 在虚拟现实环境中操纵的情景线索的影响，预计会唤起 “在当下”的认知和感觉被认为会增加性行为的可能性 有性攻击性倾向的男性的攻击性。第三个具体目标涉及检查 在虚拟现实模拟中，急性饮酒对男性性攻击性反应的影响。 根据与特定目标2相关的研究结果，情景因素将被操纵 导致2(酒精状态：清醒与醉酒；目标Brac=0.08)X 2(高或低水平的提示 影响参与者对女性性兴趣的感知)X 2(影响 参与者的权利感和拒绝后的愤怒)设计。与性侵犯相关的危险因素 犯罪行为将在单独的会议上进行评估，预计将与酒精和线索相互作用 条件，如醉酒的男子容易受到性侵犯(例如，先前存在的高水平) 指充满敌意的男子气概)，并暴露在性兴趣和权利/愤怒暗示中 很可能是性侵犯。未来的研究可以改变模拟的各个方面，以增加泛化能力 给不同的人群。申请者的长期目标是确定可修改的风险和保护因素 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。
