Alcohol's Role in Sexual Assault: Development of Virtual Reality Simulation Proxy

描述（由申请人提供）：大约一半的性侵犯涉及犯罪者、受害者或两者都饮酒。这项研究的目标是开发一种虚拟现实模拟，可以用作酒精管理研究中性侵犯行为的代理。对受害者和施暴者进行的自我报告调查提供了大量关于酒精在性侵犯中的作用的重要信息；然而，因果关系不能从相关设计中建立。在酒精管理研究中，参与者可以随机分配饮酒条件，从而允许得出因果结论。实验工作者面临的主要挑战是开发具有较强构效度和实验现实性的性侵犯代理。虚拟现实环境为参与者提供了沉浸在模拟环境中的机会；因此，期望参与者的行为方式和做出的选择与他们在实验室之外的行为密切相关。拟议研究的具体目标包括开发一个虚拟现实模拟，其中有一个虚拟的女人（一个具体化的女性代理），男性参与者认为这是真实的和参与的。交互的脚本

DESCRIPTION (provided by applicant): Approximately half of all sexual assaults involve alcohol consumption by the perpetrator, victim, or both. The goal of the proposed research is to develop a virtual reality simulation that can be used as a proxy for perpetration of sexual aggression in alcohol administration studies. Self-report surveys conducted with victims and perpetrators have provided a wealth of important information about alcohol's role in sexual assault; however, causality cannot be established from correlational designs. In alcohol administration studies, participants can be randomly assigned to drink conditions, thereby allowing causal conclusions to be made. The major challenge for experimentalists is to develop proxies for sexual assault that have strong construct validity and experimental realism. Virtual reality environments 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 Specific Aims of the proposed research involve developing a virtual reality simulation with a virtual woman (an embodied female agent) that male participants rate as realistic and involving. The script of the interaction will follow that of a prototypic acquaintance sexual assault situation, allowing male participants to make choices about sexual activities in which they want to engage and (if they choose) to repeatedly try to make the female agent engage in sexual activity despite her protests. Most participants will be young, single, sexually active, heterosexual men to correspond to the demographics of most perpetrators. Focus groups and an iterative series of pilots that include cognitive interviews will be conducted with men and women to develop the simulation. Then a preliminary assessment of construct validity will be conducted by comparing self-reports of past sexual aggression, common risk factors, and responses to another proxy with participants' responses during the simulation. Also, an initial evaluation of the simulation's usefulness in alcohol administration research will be conducted by comparing the responses and actions of intoxicated and sober participants during the simulation. The findings from this study will serve as pilot data for a R01 proposal that will formally evaluate the paradigm's construct validity and usefulness in identifying men predisposed to commit sexual assault while intoxicated. Future studies can also alter various aspects of the simulation to increase generalizability to different populations. The long-term goal is to develop prevention and treatment interventions, thereby reducing rates of sexual aggression and addressing Healthy People 2020 goals. PUBLIC HEALTH RELEVANCE: Sexual assault occurs at extremely high rates and more than half involve alcohol consumption. The goal of the proposed research is to develop a virtual reality simulation of a potential sexual assault situation that can be used in experimental research. This will allow the effects of alcohol consumption on sexual aggression to be examined under controlled conditions, thereby increasing confidence that differences found between drinkers and nondrinkers are due to alcohol, not other factors.
