DESCRIPTION (provided by applicant): Our purpose is to evaluate the longer-term impact of Green Dot across the Bluegrass, an active bystanding-based randomized intervention trial in 26 high schools across Kentucky designed to reduce dating and sexual violence in a cohort of seniors as they transition into young adulthood. Our central question is: Does Green Dot continues to have an effect in changing the culture of violence acceptance and reducing violence perpetration among students exposed to Green Dot relative to those not exposed as this cohort enters young adulthood? In this prospective cohort of approximately 7,500 students, we will measure the individual level exposure to the Green Dot program and into young adulthood allowing us to estimate the risk of dating and sexual violence victimization and perpetration. Very few studies have prospectively estimated the risk of dating and sexual violence among a cohort randomized to a primary prevention intervention and followed into young adulthood. This R01 is also unique because cohort members will be followed independent of whether they do or do not attend college. Individually following this cohort of seniors represents a significant value-added and time-sensitive opportunity because the full implementation of Green Dot began in late 2011. Only now (2013-15) would we anticipate seeing an effect of Green Dot among rising seniors on changing bystanding and potentially reducing violence. Aim 1. Prospectively determine whether and how the Green Dot intervention reduces rates of teen dating and sexual violence into young adulthood by (a) changing social norms of violence acceptance, (b) increasing active bystanding, and (c) diffusing the intervention through peer networks. Approximately 7500 high school seniors who attended Kentucky high schools randomized to the Green Dot intervention (n~3750) or control schools (n~3750) will be followed 42 months into young adulthood. Aim 2. To determine the potentially modifying effects of participants' post-high school life experience on the association between exposure to the Green Dot intervention and bystanding actions, teen dating and sexual violence incidence. Post-high school experience will be categorized as attending any form of college or university versus no additional education. Specific life stressors such as relationship status, pregnancy, military deployment, family and peer violence, and substance abuse will also be explored. This cohort study is appropriately powered (¿90%) to address both aims. Comparisons will be made at 6-month intervals and across the 42-month follow-up and the interaction of intervention by time will be evaluated. Generalized Estimating Equations will be used to test the impact of Green Dot over time while taking clustering of high schools and correlation among repeated measurements among individual students into account and adjusting for confounders. This prospective cohort builds upon a large population-based and promising primary prevention intervention, designed to reduce dating and sexual violence among high school students and provides an important test of the longer-term efficacy of this program into young adulthood.

描述（由适用提供）：我们的目的是评估绿色点在蓝草中的长期影响，这是肯塔基州26个高中的一项积极的基于腰果的随机干预试验，旨在减少老年人在过渡到年轻人的老年人中的约会和性暴力。我们的中心问题是：绿点是否继续在改变暴力接受文化并减少暴露于绿色点的学生中相对于那些没有暴露于这个队列的年轻成年的学生的暴力持续影响？在这个大约7,500名学生的这一预期队列中，我们将衡量个人对绿点计划的个人水平，并进入年轻的成年，使我们能够估算约会和性暴力胜利和犯罪的风险。很少有研究前瞻性地估计了随机分配给初级预防干预措施的队列中约会和性暴力的风险，并进行了成年。该R01也是独一无二的，因为遵循队列成员会独立于他们是否上大学。在这一老年人队列中，单独地代表了一个重大的增值和时间敏感的机会，因为绿点的全部实施始于2011年底。只有现在（2013-15），我们是否会看到，我们是否会看到上升的老年人对改变旁观者的兴趣，并潜在地减少暴力。目标1。前瞻性确定绿点干预是否以及如何通过（a）改变暴力接受社会规范的青少年约会和性暴力的年轻人的成年率，（b）增加积极的胜利，以及（c）通过同伴网络扩散干预措施。大约有7500名高中生在肯塔基高中随机参加绿点干预（N〜3750）或对照学校（N〜3750）的高中，将在成年后42个月进行。目标2。确定参与者高中生生活经验对绿点干预与胜利行动，青少年约会和性暴力事件之间的关联的潜在修改影响。高中后的经验将被归类为参加任何形式的大学或大学，而没有其他教育。还将探索特定的生活压力，例如关系状况，怀孕，军事部署，家庭和同伴暴力以及滥用毒品。这项队列研究的功率是适当的（90％），以解决这两个目标。比较将以6个月的间隔和42个月的随访进行，并将评估干预的相互作用。一般的估计方程将用于测试绿点随时间的影响，同时考虑了高中的聚类，并考虑到各个学生之间的重复测量以及对混杂因素的调整。这一前瞻性队列建立在大型基于人群和承诺的主要预防干预措施的基础上，旨在减少高中生的约会和性暴力，并对年轻成年的长期有效性进行了重要的考验。
