Diffusion of Drug Prevention Curricula Nationwide

描述(由申请人提供)： 这项拟议研究的目的是调查全国中学预防药物使用实践的进展情况。这项研究将建立在早些时候的一项研究(NIDA R01 DA11492)的基础上，该研究于1999年调查了中学-学区二元领导预防教师和学区协调员。回到我们最初的样本，并使用基于网络的数据收集策略，我们将在2004年和2007年从我们的受访者二人组管理另外两轮数据。我们将收集信息，阐明在学校范围内传播循证课程的三个主要过程。这些过程是：(1)采用，这是指一个组织选择一个创新计划的初步决定；(2)实施，它涉及该计划在特定背景下如何实际实施，包括计划的保真度，或计划按预期管理的程度；以及适应，它指的是对该计划的内容或教学方法的修改；(3)可持续性，它涉及该计划随着时间的推移在其主办组织中的嵌入程度。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普及率随时间的变化；(2)循证药物使用预防课程实施质量随时间的变化；(3)国家两大循证药物使用预防课程项目ALERT和LST的忠实实施程度，以及它们如何在课堂上适应，以及(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。研究结果将揭示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机会，将分配给安全和无毒品学校的资金中高达50%的资金转移到其他优先事项。

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.
