A Follow-up of Classroom Services to Prevent Drug Use

说明（由申请人提供）：本R01申请一项为期五年的预防服务项目，以：1)通过三年级测试一年级课堂干预在两个队列中的影响，这两个队列是第一队列的系统重复，2)检查干预影响的变化，以确定什么对哪些儿童在哪些条件下有效，特别关注反应者与无反应者，3)加强对持续实践和规模的多层次模型的测试。全天一年级计划（WD）针对两个相关的和确认的药物滥用和其他共病障碍的早期前例，早期攻击性，破坏性行为和不良成就。WD关注教师的课堂行为管理、家庭/课堂在作业和纪律方面的合作关系，以及教师的教学实践，特别是在阅读方面。一个随机的，基于流行病学的实验设计，同时，一个全天一年级计划（WD）的有效性试验和一个多层次支持结构的效用测试，以维持和传播WD，如数据证明。12所学校的教师和一年级学生被随机分配到干预或标准项目教室。我们已经完成了对第一组（2003-04学年）一年级学生为期一年的有效性试验，并将跟踪该组学生至三年级。我们还跟踪了一年级教师，因为他们教了随后的两组一年级学生，以测试这种多层次的培训和支持结构是否能维持高水平的WD实践，以及它是否可以用于培训非WD教师。这个独立的R01需要资金来收集随后两个一年级学生队列的数据，他们将作为队列1的系统重复。数据将在一年级和三年级春季收集。我们还寻求保留第2组和第3组的关键干预人员，以加强项目传播的多层次模式。该应用程序建立在当前工作的基础上，以最大限度地提高开发、复制和扩展到全系统使用的循证预防方案的成本和时间效率。

DESCRIPTION (provided by applicant): This R01 is to request a five-year prevention services project to: 1) test the impact, through third grade, of a first-grade cLassroom-based intervention in 2 cohorts which are systematic replicates of a 1st cohort, 2) examine the variation in intervention impact to determine what works for which children under which conditions with a specific focus on the responders versus non-responders, and 3) strengthen the test of multi-level model for sustaining practices and going-to-scale. The Whole Day First Grade Program (WD) is directed at two correlated and confirmed early antecedents of drug abuse and other co-morbid disorders, early aggressive, disruptive behavior and poor achievement. WD focuses on teachers' classroom behavior management, family/classroom partnerships regarding homework and discipline, and teachers' instructional practices, particularly around reading. A randomized, epidemiologically-based, experimental design addresses, in parallel, an effectiveness trial of the Whole Day First Grade Program (WD) and a test of the utility of a multi-level support structure to sustain and disseminate WD, as the data warrant. Teachers and 1st graders within each of 12 schools were randomized to an intervention or standard program classroom. We have completed one year of an effectiveness trial with 1st graders in Cohort 1 (school year 2003-04) and are following this cohort to 3rd grade. We are also following the 1st grade teachers as they teach 2 subsequent cohorts of 1st graders to test whether the multi-level structure of training and support sustains high levels of WD practice and if it can be used to train non-WD teachers. This independent R01 requests funds to collect data on the 2 subsequent cohorts of 1st grade students, who will serve as systematic replicates of Cohort 1. Data will be collected in 1st grade and in spring of 3rd grade. We also seek to retain key intervention staff over Cohorts 2 and 3 to strengthen the multi-level model of program dissemination. The application builds upon current work to maximize efficiency of both costs and time in developing, replicating and extending to system-wide use evidence-based prevention programs.
