Project Summary One in five undergraduate women experience sexual assault (SA) during their college career, most commonly under the influence of acute alcohol intoxication. One critical mechanism through which intoxication increases risk for SA is a reduced ability to perceive SA risk cues due, in part, to the diminished attentional capacity that occurs during intoxication. While laboratory studies have consistently observed greater reductions in SA risk perception among intoxicated versus non-intoxicated women, the potential influence of state emotion on SA risk perception during acute alcohol intoxication remains unexplored. This is a critical gap given theoretical evidence to suggest that SA risk perception may be influenced by both negative and positive state emotions. Accordingly, the proposed study will assess the roles of negative and positive emotion states and acute alcohol intoxication on SA risk perception (Aim 1) as well as identify subjective (e.g., self-report) and objective (e.g., electrodermal response [EDA], heart rate variability [HRV]) indices of emotion states that underlie changes in SA risk perception during acute alcohol intoxication (Aim 2). In a single experimental session, participants (i.e., undergraduate women aged 21 and older who use alcohol) will be randomly assigned to one of two alcohol conditions (i.e., alcohol or no-alcohol) and one of three idiographic emotion induction conditions (i.e., positive, negative, or neutral) prior to completing a SA risk perception task. Participants assigned to the acute alcohol intoxication condition will be administered alcohol to achieve a target BAC of .08 (i.e., a dose of alcohol equivalent to approximately four standard alcohol drinks). Positive, negative, or neutral emotion state will be achieved using a validated idiographic emotion induction task. SA risk perception will be measured using a hypothetical SA vignette designed to assess instances of discomfort and decision of when to leave the hypothetical scenario. Subjective intensity and regulation of state emotion will be assessed via self-report measures administered pre- and post- emotion induction as well as post-SA risk perception task. EDA and HRV will capture objective arousal and regulation of state emotion, respectively, and will be measured continuously during the experimental session with the BIOPAC MP36. This study is the first to utilize a laboratory-based, multi-method approach to explicate the roles of state emotion and acute alcohol intoxication on SA risk perception. In alignment with the NIAAA strategic plan, findings will help develop and improve strategies to reduce and prevent alcohol-related harm, such as SA among undergraduate women. Additionally, the proposed project would provide the Applicant with training that will inform her future research on the intersection of SA and alcohol, including via the development of skills necessary for conducting sophisticated experimental paradigms relevant to the study of state emotions (e.g., use of biomarkers), acute effects of alcohol (e.g., alcohol administration), and SA risk perception (e.g., vignette methodology). 2

项目概要 五分之一的本科女性在大学生涯中经历过性侵犯（SA），最常见 在急性酒精中毒的影响下。中毒增加的一种关键机制 SA 的风险是感知 SA 风险线索的能力下降，部分原因是注意力能力下降 发生在中毒期间。虽然实验室研究一致观察到 SA 风险显着降低 醉酒与非醉酒女性的感知，状态情绪对 SA 的潜在影响 急性酒精中毒期间的风险感知仍有待探索。考虑到理论上，这是一个关键差距 有证据表明，SA 风险感知可能受到消极和积极状态情绪的影响。 因此，拟议的研究将评估消极和积极情绪状态以及急性酒精的作用 中毒对SA风险认知（目标1）以及识别主观（例如自我报告）和客观（例如， 皮肤电反应 [EDA]、心率变异性 [HRV]）是导致情绪变化的情绪状态指数 急性酒精中毒期间的 SA 风险感知（目标 2）。在一次实验中，参与者（即 21 岁及以上饮酒的本科女性）将被随机分配到两种酒精中的一种 条件（即酒精或无酒精）和三种特定情绪诱导条件之一（即积极、 在完成 SA 风险认知任务之前。参与者被分配到急性酒精组 中毒情况下将给予酒精以达到 0.08 的目标 BAC（即一定剂量的酒精） 相当于大约四杯标准酒精饮料）。积极、消极或中性的情绪状态将是 使用经过验证的具体情感诱导任务来实现。 SA 风险感知将使用 假设的 SA 小插曲，旨在评估不适情况并决定何时离开 假设场景。状态情绪的主观强度和调节将通过自我报告进行评估 测量情绪诱导前和情绪诱导后以及 SA 后风险感知任务。电子设计自动化和 HRV 将分别捕获状态情绪的客观唤醒和调节，并将进行测量 在使用 BIOPAC MP36 进行实验期间连续进行。本研究首次利用 基于实验室的多方法方法来阐明状态情绪和急性酒精中毒的作用 关于 SA 风险认知。根据 NIAAA 战略计划，调查结果将有助于开发和改进 减少和预防酒精相关伤害的策略，例如本科女性的 SA。此外， 拟议的项目将为申请人提供培训，为她未来的研究提供信息 SA 和酒精的交叉点，包括通过发展进行复杂的操作所需的技能 与状态情绪研究相关的实验范式（例如，生物标志物的使用）、情绪的急性影响 酒精（例如酒精管理）和 SA 风险认知（例如小插图方法）。 2
