A Follow-up of Classroom Services to Prevent Drug Use

描述(由申请人提供)：本R01要求一个为期五年的预防服务项目：1)通过三年级，在2个队列中测试一年级课堂干预的影响，这两个队列是第一个队列的系统复制；2)检查干预影响的变化，以确定在哪些条件下什么对哪些儿童有效，并特别关注响应者和非响应者；以及3)加强多层次模式的测试，以维持实践和进入规模。全天一年级计划(WD)针对的是两个相互关联和确认的早期药物滥用和其他共病障碍的前驱因素，早期攻击性、破坏性行为和成绩不佳。WD的重点是教师的课堂行为管理，家庭/课堂上关于家庭作业和纪律的合作伙伴关系，以及教师的教学实践，特别是围绕阅读的教学实践。一项基于流行病学的随机实验设计同时进行了全天一年级计划(WD)的有效性试验，并根据数据保证测试了维持和传播WD的多层次支持结构的效用。12所学校中的教师和一年级学生被随机分配到干预或标准课程课堂。我们已经完成了第一组(2003-04学年)一年级学生的一年有效性试验，并正在跟踪这一组到三年级。我们还跟踪了一年级教师，因为他们在教授随后的两批一年级学生时，测试多层次的培训和支持结构是否能够维持高水平的WD实践，以及它是否可以用于培训非WD教师。这个独立的R01申请资金来收集随后的两个一年级学生的数据，他们将作为第一个队列的系统复制。数据将在一年级和三年级的春季收集。我们还寻求保留关键干预人员超过队列2和3，以加强方案传播的多层次模式。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计划的成本和时间效率。

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.
