DESCRIPTION (provided by applicant): The purpose of this proposed five-year MERIT project extension is to continue a longitudinal, controlled study of a universal, multicomponent intervention initially implemented with rural youth and families. The proposed plan is to follow our sample during late emerging adulthood, a phase critically important to the establishment of enduring patterns of substance use and substance-related problems affecting healthy adult functioning. The MERIT project research to date has addressed several key methodological problems typical in community-based preventive intervention research-in part, through the use of multimethod, multi-informant measurement procedures. Intervention and measurement demands of the study notwithstanding, the targeted schools (N = 36) were successfully recruited from a randomly selected set of schools and randomly assigned to a multicomponent family- and school-based intervention, a school-based intervention alone, and control conditions; all schools were retained through the 12th grade data collection point. Observation-based assessment confirmed high fidelity implementation of both family and school intervention components. Eighty- six percent of the pretest sample remained through the last wave of data analyzed post high school; there has been no loss of sample size in the post high school sample. The study also has addressed major gaps in the knowledge base on long-term effects of multicomponent family and school-based interventions in understudied populations; substantial progress has been achieved on all of the specific research aims in the original proposal. Notably, positive long-term substance initiation outcomes have been demonstrated through early emerging adulthood, with stronger effects among higher-risk participants and empirical verification of mediated effects through a protective shield of reduced substance use opportunities, along with evidence of economic benefits. A key indicator of initial progress overall is the completion of 46 manuscripts, among a total of over 150 manuscripts produced since 1993 through the larger program of research of which it is a part. The proposed study will evaluate long-term effects of a universal, multicomponent middle school intervention on participants in the late emerging adulthood phase; specifically, effects on substance use and related adult functioning (criminal and antisocial behavior, mental health, physical health, relationship quality and sexual behavior-Aim 1). In addition, it will examine mediating mechanisms of long-term multicomponent intervention effects on emerging adult substance use and related adult functioning, replicating and extending models empirically supported by earlier research (Aim 2). Finally, the project also will examine moderation of long-term intervention effects associated with early adolescent risk and the alteration of problem behavior trajectories associated with attending college and other life course changes (Aim 3). PUBLIC HEALTH RELEVANCE: The proposed study examines how preventive interventions designed for general populations can have substantial public health impact. It extends earlier outcome research that already has demonstrated practically significant relative reduction rates for a number of substances, including prescription drug misuse (relative reduction up to 50%), stronger effects among higher-risk participants, and evidence of economic benefits (e.g., over $9 estimated return for every dollar invested). Further potential public health and economic benefits will be evaluated by studying long-term effects of interventions-originally implemented in understudied rural middle schools-among participants when they are in their late 20s.

描述（由申请人提供）：拟议的五年优异项目扩展的目的是继续对最初与农村青年和家庭实施的通用多组分干预措施进行纵向，对照研究。拟议的计划是在成年后期遵循我们的样本，这对于建立持久的药物使用模式和影响健康成人功能的物质问题至关重要。 迄今为止，优异的项目研究通过使用多方法，多信息测量程序来解决基于社区的预防性干预研究中的几个关键方法论问题。尽管对研究的干预和衡量要求，但目标学校（n = 36）还是从随机选择的一组学校中成功招募，并随机分配给多组分家庭和基于学校的干预措施，仅基于学校的干预措施和控制条件；所有学校均通过12年级的数据收集点保留。基于观察的评估证实了家庭和学校干预组件的高保真实施。预测试样本中有80％是通过高中分析的最后一波数据浪潮保留的；高中样本中没有损失样本量。该研究还解决了知识基础上关于多组分家庭和基于学校干预措施的长期影响的主要差距。在原始提案中，所有具体研究的目的都取得了重大进展。值得注意的是，通过新兴的成年早期证明了积极的长期物质起始成果，在高风险的参与者中产生更强的影响，并通过保护性减少的物质使用机会的保护性以及经济利益的证据，对中介作用的经验验证。最初进步的关键指标总体上是完成了46份手稿，在自1993年以来通过更大的研究计划生产的总共150多个手稿中，它是其中的一部分。 拟议的研究将评估普遍的多组分中学干预对新兴成年阶段参与者的长期影响；具体而言，对药物使用和相关成人功能的影响（犯罪和反社会行为，心理健康，身体健康，关系质量和性行为-AIM 1）。此外，它将研究长期多组分干预对新兴成人物质使用和相关成人功能的影响，复制和扩展模型在较早的研究经验上得到验证（AIM 2）。最后，该项目还将研究与早期青少年风险相关的长期干预效应的适度，以及与上大学和其他生活课程变化相关的问题行为轨迹的改变（AIM 3）。 公共卫生相关性： 拟议的研究研究了为普通人群设计的预防干预措施如何对公共卫生产生重大影响。它扩展了较早的结果研究，这些研究已经显示出许多物质的实际相对降低率，包括处方药滥用（相对降低高达50％），高风险参与者的效果更强以及经济利益的证据（例如，每笔投资的估计收益率超过9美元）。将通过研究20多岁时，在研究不足的农村中学参与者中实施干预措施的长期影响，将评估进一步的公共卫生和经济益处。
