A Follow-up of Classroom Services to Prevent Drug Use

描述（由申请人提供）：本R 01申请一项为期五年的预防服务计划，以：1）在2个队列中测试一级基于教室的干预的影响，直到三年级，这2个队列是第一队列的系统复制，2）检查干预影响的变化，以确定在何种条件下对哪些儿童有效，特别关注响应者与非响应者，3）加强多层次模型的检验，促进实践的可持续性和规模化。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疾病，早期侵略性，破坏性行为和成绩差的早期前因。WD侧重于教师的课堂行为管理，家庭/课堂伙伴关系有关的家庭作业和纪律，教师的教学实践，特别是围绕阅读。一个随机的，流行病学为基础的，实验设计地址，在平行，全天一年级计划（WD）的有效性试验和测试的效用的多层次的支持结构，以维持和传播WD，作为数据保证。12所学校的教师和一年级学生被随机分配到干预或标准课程教室。我们已经完成了一年的有效性试验，一年级学生在队列1（2003-04学年），并遵循这一队列到三年级。我们还跟踪一年级教师，因为他们教2个一年级学生的后续队列，以测试培训和支持的多层次结构是否维持高水平的WD实践，如果它可以用来培训非WD教师。这个独立的R 01要求资金收集数据的2个后续队列的一年级学生，谁将作为队列1的系统复制。数据将在一年级和三年级春季收集。我们还寻求保留第2和第3组的关键干预人员，以加强计划传播的多层次模式。该应用程序建立在目前的工作，以最大限度地提高成本和时间的效率，在开发，复制和推广到全系统使用循证预防方案。

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.
