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（由申请人提供）：我们的目的是评估绿色点在蓝草中的长期影响，这是一项在肯塔基州26所高中进行的基于旁观者的随机干预试验，旨在减少老年人过渡到年轻人时的约会和性暴力。我们的中心问题是：绿色点是否继续在改变暴力接受文化和减少暴力犯罪的学生接触绿色点相对于那些没有接触，因为这个队列进入青年成年？在这个大约7,500名学生的前瞻性队列中，我们将测量绿色点计划的个人水平暴露，并进入青年期，使我们能够估计约会和性暴力受害和犯罪的风险。很少有研究前瞻性地估计了随机分配到一级预防干预并随访至青年期的队列中的约会和性暴力风险。这个R 01也是独一无二的，因为队列成员将被独立于他们是否上大学。单独跟踪这批老年人是一个重要的增值和时间敏感的机会，因为绿色点的全面实施始于2011年底。只有现在（2013-15年），我们才能看到绿色点在老年人中的作用，改变旁观者的地位，并可能减少暴力。目标1.普罗维登斯决定是否以及如何绿色点干预减少率的青少年约会和性暴力进入年轻的成年人（a）改变社会规范的暴力接受，（B）增加积极的旁观，（c）通过同伴网络扩散的干预。随机分配到绿色点干预学校（n~3750）或对照学校（n ~ 3750）的约7500名就读于肯塔基州高中的高中毕业生将被随访42个月，直至成年。目标2.确定参与者高中后生活经历对接触绿色点干预与旁观行为、青少年约会和性暴力发生率之间关联的潜在修正作用。高中后的经历将被归类为参加任何形式的学院或大学与没有额外的教育。具体的生活压力，如关系状况，怀孕，军事部署，家庭和同伴暴力，药物滥用也将进行探讨。这项队列研究具有适当的把握度（约90%）来解决这两个目标。将每隔6个月进行一次比较，并在42个月的随访期间进行比较，并评价干预与时间的相互作用。将使用广义估计方程检验绿色点随时间的影响，同时考虑高中的聚类和个体学生之间重复测量的相关性，并调整混杂因素。这一前瞻性队列建立在一个庞大的人口为基础的和有前途的初级预防干预，旨在减少高中生之间的约会和性暴力，并提供了一个重要的测试，该计划的长期功效进入青年成年。
