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

项目摘要 五分之一的本科女性在大学生涯中经历过性侵犯（SA），最常见的是 在急性酒精中毒的影响下一个关键的机制，通过中毒增加 SA的风险是感知SA风险线索的能力降低，部分原因是注意力能力降低， 发生在中毒期间。虽然实验室研究一致观察到SA风险的更大降低 醉酒与非醉酒妇女之间的感知，状态情绪对SA的潜在影响 急性酒精中毒时的风险感知仍未被探索。这是一个关键的差距， 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的情绪状态和急性酒精的作用 中毒对SA风险感知（目标1）以及识别主观（例如，自我报告）和目标（例如， 皮肤电反应[EDA]，心率变异性[HRV]）的情绪状态的指标，这些指标是 急性酒精中毒期间的SA风险感知（目的2）。在单个实验会话中，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，积极的， 消极的，或中性的），然后完成SA风险感知任务。参与者被分配到急性酒精 将对中毒状况施用酒精以达到0.08的目标BAC（即，一剂酒精 相当于四种标准酒精饮料）。积极、消极或中性的情绪状态将被 使用经过验证的具体情绪诱导任务实现。SA风险感知将使用 假设的SA小插曲，旨在评估不适的情况，并决定何时离开 假设的场景将通过自我报告评估状态情绪的主观强度和调节 测量前和后情绪诱导以及后SA的风险知觉任务。EDA和 HRV将分别捕获状态情绪的客观唤醒和调节，并将被测量 在使用BIOPAC MP36的实验阶段期间连续进行。这项研究是第一次利用一个 以实验室为基础的多方法方法来解释状态情绪和急性酒精中毒的作用 对SA风险的认知。根据NIAAA战略计划，调查结果将有助于制定和改进 减少和预防酒精相关伤害的策略，例如本科女生中的SA。此外，本发明还 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 与状态情绪研究相关的实验范例（例如，生物标志物的使用）， 醇（例如，酒精施用），和SA风险感知（例如，小插图方法）。 2
