Assessing State Emotions and Acute Alcohol Intoxication on Sexual Assault Risk Perception

项目摘要 五分之一的本科生女性在大学生涯中经历过性侵，这是最常见的 在急性酒精中毒的影响下。醉酒增加的一个关键机制 对SA来说，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减弱， 发生在醉酒期间。虽然实验室研究一直在观察到SA风险的更大降低 醉酒与未醉酒女性的知觉，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未被探索。从理论上讲，这是一个严重的差距 有证据表明，SA风险知觉可能同时受到消极和积极状态情绪的影响。 因此，这项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 醉酒对SA风险感知(目标1)以及识别主观(例如，自我报告)和客观(例如， 电皮肤反应[EDA]，心率变异性[HRV])情绪状态的指数，是 急性酒精中毒期间的SA风险感知(目标2)。在单个实验会话中，参与者(即， 21岁及以上饮酒的本科生女性)将被随机分配到两种酒精中的一种 条件(即，酒精或不酒精)和三个具体情绪诱导条件之一(即，积极的， 在完成SA风险感知任务之前)。被分配到急性酒精组的参与者 在醉酒的情况下，给予酒精以达到0.08的目标BAC(即一剂酒精 大约相当于四种标准酒精饮料)。积极、消极或中性的情绪状态将是 使用经过验证的具体情绪诱导任务实现。SA风险感知将使用 假想的SA小插曲旨在评估不适的情况和决定何时离开 假设的情景。状态情绪的主观强度和调节将通过自我报告进行评估 采用情绪诱导前后和SA后风险感知任务的测量。EDA和 心率变异性将分别捕捉客观唤醒和状态情绪调节，并将被测量 在使用Biopac MP36进行实验的过程中不断进行测试。这项研究是第一次利用 以实验室为基础的多方法解释状态情绪和急性酒精中毒的作用 关于SA风险认知。与NIAAA战略计划保持一致，调查结果将有助于发展和改进 减少和预防与酒精有关的伤害的战略，例如在本科生女性中的SA。另外， 拟议的项目将为申请者提供培训，为她未来对 SA和酒精的交叉，包括通过开发进行尖端操作所需的技能 与状态情绪研究相关的实验范式(例如，使用生物标记物)，急性影响 酒精(如饮酒)和SA风险认知(如Vignette方法)。 2.

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
