Diffusion of Drug Prevention Curricula Nationwide

描述（由申请人提供）： 本研究的目的是调查全国中学物质使用预防实践的进展情况。该研究将建立在早期研究（NIDA R 01 DA 11492）的基础上，该研究于1999年调查了中学-学区二元结构中的主要预防教师和学区协调员。回到我们最初的样本，并使用基于Web的数据收集策略，我们将管理另外两轮的数据，在2004年和2007年，从我们的受访者二对。我们将收集信息，以阐明三个主要过程，是关键的循证课程在学校环境中的传播。这些过程是：（1）采用，指组织对选择一项创新方案的最初决定;（2）实施，指方案如何在特定环境中实际实施，既包括忠实性，即方案按预期管理的程度，也包括适应性，即对方案内容或教学方法的修改;以及（3）可持续性，这涉及到随着时间的推移，该计划在其主办组织中嵌入的程度。利用1999年、2004年和2007年的三轮数据，我们将调查：（1）全国中学和学区采用循证药物使用预防课程的流行率随时间的变化，（2）循证药物使用预防课程实施质量随时间的变化，（3）全国两个杰出的循证课程-ALERT项目和LST-的忠实实施程度，以及它们在课堂上的适应情况;（4）与这些课程和一般循证预防课程的可持续性有关的因素。研究结果将有助于了解2002年年中颁布的“不让一个孩子掉队”立法的效果，该立法为地方教育当局提供了机会，可将分配给安全无毒学校的资金的50%转用于其他优先事项。

DESCRIPTION (provided by applicant): The purpose of the proposed study is to investigate progress in the state of substance use prevention practice in the nation's middle schools. The study will build on an earlier study (NIDA R01 DA11492) that surveyed, in 1999, lead prevention teachers and school district coordinators in middle school - school district dyads. Returning to our original sample and using a Web-based data collection strategy, we will administer two additional rounds of data, in 2004 and 2007, from our respondent dyads. We will collect information to elucidate three major processes that are key to the dissemination of evidence-based curricula in school contexts. These processes are: (1) adoption, which refers to an organization's initial decision to select an innovative program; (2) implementation, which concerns how the program is actually implemented in a particular context and which encompasses both fidelity, or the degree to which programs are administered as intended, and adaptation, which refers to modifications to the program's content or didactic methods; and (3) sustainability, which concerns the degree to which the program becomes embedded in its host organization over time. Using the three rounds of data from 1999, 2004, and 2007, we will investigate: (1) changes over time in the prevalence with which evidence-based substance use prevention curricula have been adopted by the nation's middle schools and school districts, (2) changes over time in the quality of implementation of evidence-based substance use prevention curricula, (3) the degree to which the nation's two preeminent evidence-based curricula, Project ALERT and LST have been implemented with fidelity, and how they have been adapted in the classroom, and (4) factors related to the sustainability of these curricula and of evidence-based prevention curricula in general. Study results will shed light on the effects of the "No Child Left Behind" legislation, enacted in mid-2002, which provides local education authorities the opportunity to transfer to other priorities up to 50 percent of funds allocated to Safe and Drug-Free Schools.
