项目摘要

PROJECT SUMMARY During young adulthood, an estimated one in five women experience sexual assault. We seek to reduce this violence by motivating young adults to intervene with their peers to prevent sexual assault—an approach known as bystander intervention. Current bystander training is conducted in group sessions involving education about how to recognize and intervene in response to sexual risk situations. Although successful in changing knowledge and attitudes about sexual assault prevention, evaluations of these programs have rarely focused on changing actual bystander behaviors. Further, while bystander alcohol use is common in sexual risk situations, and undermines intervention attempts, alcohol consumption by bystanders is not explicitly targeted in existing intervention training programs. To address these gaps, we will conduct a RCT comparing the efficacy of: 1) our recently developed bystander intervention, Motivate-the-Bystander (MTB), 2) MTB with an MI alcohol component (MTB+ALC), and 3) an attention control condition for reducing alcohol use and increasing bystander behaviors in response to sexual risk. Bystander behaviors will be assessed observationally during a virtual reality-based house party at 2 months post intervention. Participants’ bystander behaviors, alcohol use, and relevant contextual variables will be assessed with a measurement burst design using electronic daily diaries at baseline and 3, 6, and 9 months post intervention. We expect that, compared to MTB alone and the control condition, MTB+ALC will produce significantly greater reductions in overall drinking and increases in prosocial bystander behaviors in a diverse sample of 450 young adults who are heavy drinkers. If our hypotheses are confirmed, results will support the use of our combined MI-based bystander-alcohol intervention as an effective means of reducing drinking and motivating bystander behaviors among those at highest risk for sexual violence.

项目总结据估计，在年轻的成年时期，五分之一的女性经历过性侵。我们寻求减少这种暴力通过激励年轻人与他们的同龄人进行干预来防止性侵犯--一种方法被称为旁观者干预。目前的旁观者培训是以小组形式进行的，包括教育如何识别和干预性风险情况。虽然在改变了对性侵犯预防的知识和态度，对这些项目的评估很少专注于改变实际的旁观者行为。此外，虽然旁观者饮酒在性行为中很常见危险情况，并破坏干预企图，旁观者的饮酒行为不明确在现有的干预培训计划中有针对性。为了解决这些差距，我们将进行RCT比较 1)我们最近开发的旁观者干预，激励旁观者(MTB)，2)MTB与 MI酒精成分(MTB+ALC)，以及3)用于减少酒精使用的注意力控制条件和因应性风险而增加旁观者的行为。旁观者的行为将通过观察来评估在基于虚拟现实的家庭聚会上，在干预后2个月。参与者的旁观者行为，酒精使用，以及相关的背景变量将使用测量突发设计进行评估干预后3个月、6个月和9个月的电子日记。我们预计，与MTB相比单独和控制条件下，MTB+ALC将显著更大地减少总饮酒量和在450名酗酒的年轻人中，亲社会旁观者行为的增加。如果我们的假设得到证实，结果将支持使用基于MI的联合旁观者酒精干预是减少饮酒和鼓励旁观者行为的有效手段性暴力风险最高。
