Abstract 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).

摘要 拟议的MERIT项目五年延期的目的是继续进行纵向、受控的 对一项普遍的、多方面的干预措施进行研究，最初是在农村青年和家庭中实施的。的 一个提议的计划是在成年后期跟踪我们的样本，这是一个对我们的研究至关重要的阶段。 确定影响健康成人的物质使用和物质相关问题的持久模式 功能 MERIT项目迄今为止的研究已经解决了几个典型的关键方法问题， 以社区为基础的预防性干预研究--部分是通过使用多方法、多知情人 测量程序.尽管有研究的干预和测量要求， 从随机选择的一组学校中成功招募了36所学校，并随机分配 一个多方面的家庭和学校为基础的干预，一个学校为基础的干预， 条件;所有学校都通过12年级数据收集点保留。基于观测 评估证实，家庭和学校干预部分的实施情况非常真实。八十- 6%的预测试样本仍然通过最后一波数据分析后高中;有 在高中后的样本中没有损失样本量。该研究还解决了 以家庭和学校为基础多方面干预措施的长期影响的知识基础， 研究不足的人群;在所有具体的研究目标方面都取得了实质性进展， 原创提案值得注意的是，积极的长期物质启动结果已被证明， 成年早期，在高风险参与者中具有更强的影响， 通过减少物质使用机会的保护屏障介导的影响，沿着证据表明 经济效益总体初步进展的一个关键指标是完成了46份手稿， 自1993年以来，通过更大的研究计划，它是其中的一部分，产生了150多份手稿。 这项拟议中的研究将评估一个普遍的、多成分的中学的长期影响。 对成年期后期参与者的干预;特别是对物质使用和 相关成人功能（犯罪和反社会行为，心理健康，身体健康，关系质量 性行为（目标1）。此外，它将研究长期多组分的调解机制， 干预对新出现的成人物质使用和相关成人功能的影响，复制和扩展 早期研究经验支持的模型（目标2）。最后，该项目还将审查 与青少年早期风险和问题行为改变相关的长期干预效果 与上大学和其他人生历程变化相关的轨迹（目标3）。
