Investing in Prevention Infrastructure: Economic Evaluation of the PROSPER System

项目摘要 拟议的研究将评估由NIDA资助的主要预防、提供和支助的经济影响 称为Prosper(促进)的循证预防干预系统(EBPI) 学校/社区-大学伙伴关系以增强复原力)。这项研究将建立在现有的 Prosper的随机试验，为农村社区超过12,000名青年提供EBPI，时间为18至20年 并培育了持续的高质量的地方预防工作。这些社区预防小组被选为 并对6、7年级的初中生实施了以家庭为中心的校本EBI。首字母 评估跟踪学生从测试前(6年级)到12年级(干预后5年)。 先前资助的研究指出，在干预中减少物质滥用的一致发现 参与者。这些较早的发现需要对经济影响进行进一步调查。因此， 拟议的研究将使我们能够评估干预的长期影响将如何转化为经济 从成年到成年都会受益。除了估计繁荣系统的全部经济影响外，我们还将 评估当地计划执行情况和支持性系统因素可能如何影响 普遍的预防努力，提供关于如何建立有效的药物滥用的必要信息 预防工作。 这项研究的具体目的是：(1)评估繁荣模型对经济的影响 防止物质滥用；(2)模拟当地预防基础设施的变化如何影响 经济影响；以及(3)评估个别风险因素如何影响预防效率。前期工作 演示了计划交付所需的资源如何在 预防交付系统，培养可持续的资金流，以支持长期传播。这个 拟议的研究将通过评估这些提高的效率如何改进来跟踪这项调查 干预效果产生正经济效益的可能性。重要的是，这次调查 将在计划实施因素不同的情况下检查预期经济结果的范围 交付，利用评估这一点的独特的详细数据。此外，对经济影响的调查可能 由于参与者特征的不同，将进一步向政策制定者通报可能的结果范围 预期中。因此，这项研究提供了一个独特的机会来确定 有效的预防交付系统对减少药物滥用和危险行为的影响 青少年。

Project Summary The proposed study will evaluate the economic impact of a major NIDA-funded prevention delivery and support system for evidence-based preventive interventions (EBPIs) known as PROSPER (PROmoting School/community-university Partnerships to Enhance Resilience). This research will build on the existing randomized trial of PROSPER that delivered EBPIs to over 12,000 youth in rural communities 18 to 20 years ago and cultivated sustained high-quality local prevention efforts. These community prevention teams selected and implemented family-focused and school-based EBIs for middle school students in 6th and 7th grade. Initial assessments followed students from pretest (6th grade) through 12th grade (five years post-intervention). Prior funded research pointed to consistent findings for reduced substance misuse among intervention participants. These earlier findings warrant further investigation of the economic implications. Consequently, the proposed study will allow us to assess how long-term effects of the intervention will translate into economic benefits through adulthood. Beyond estimating the full economic impact of the PROSPER system, we will also assess how local program implementation and supportive systemic factors may influence the efficiency of universal prevention efforts, providing needed information around how to build efficient substance abuse prevention efforts. The specific aims of this study are to: (1) Evaluate the economic impact of the PROSPER model for preventing substance misuse; (2) Model how variation in local prevention infrastructure influences economic impact; and (3) Assess how individual risk factors impact prevention efficiency. Prior work demonstrated how the resources necessary for program delivery can be managed more efficiently within a prevention delivery system that cultivates sustainable funding streams to support long-term dissemination. The proposed research would follow this investigation by evaluating how these increased efficiencies can improve the likelihood for positive economic benefit resulting from intervention effectiveness. Importantly, this inquiry will examine the range of expected economic outcomes given variation in implementation factors for program delivery, leveraging unique detailed data assessing this. Further, investigations of how economic impact may vary due to participant characteristics will further inform policy makers of the range of outcomes that could be expected. Thus, this research provides a unique opportunity to determine the long-term economic benefit from an efficient prevention delivery system’s impact on reduced substance misuse and risky behavior among adolescents.
