DIFFERENTIAL EFFECTIVENESS IN DRUG PREVENTION PROGRAMS

描述：（申请人提供） 本建议的目的是调查一个有效的， 针对高危青少年的药物滥用预防计划， 国家药物滥用研究所呼吁新一代的 药物滥用预防研究。该提案利用了刚刚完成的 重新联系青年（RY）预防计划的复制研究 由教育部资助（DOE #S184F970055）。 这项DOE研究提供了890名高危青少年的样本， 分配给控制条件或RY预防程序。的 这项研究得到了严格的实施，并有广泛的基线， 参与者的纵向措施，包括计划后和5个月 后续行动;广泛的进程评价数据衡量了 RY计划包括41项基于小组的干预措施。 建议进行约30个月的长期随访，以评价 的长期疗效的RY计划，并提供详细的 定量分析干预的理论基础。的 后者直接解决了指定的干预组件如何发挥作用， 达到预期的结果（减少药物参与和增加情绪 管理和学校绩效）。分析还提供了详细的评估 RY干预机制和小组的特点 特征影响实验结果。最后，详细 定量和定性分析，根据重新抽样100 个人进行深入采访，探讨青年谁是类别 成功或未能取得预期成果的人，特别是 关于毒品问题。该研究应告知具体情况， RY干预措施的有效性，并更普遍地促进预防 科学界理解干预战略的组成部分的能力 成功地减少了药物参与和相关的并发症 问题行为

DESCRIPTION: (provided by the applicant) The purpose of this proposal is to investigate the components of an effective, indicated drug abuse prevention program for high risk youth and directly address the National Institute on Drug Abuse's call for a new generation of drug abuse prevention studies. The proposal takes advantage of a just completed replication study of the Reconnecting Youth (RY) indicated prevention program funded by the Department of Education (DOE # S184F970055). This DOE study provides a sample of 890 at-risk youth who were randomly assigned to either a control condition or to the RY prevention program. The study has been rigorously implemented and has extensive baseline and longitudinal measures for participants, including post-program and a 5 month follow-up; extensive process evaluation data measures the implementation of the RY program across 41 group-based interventions. A long-term follow-up, at approximately 30 months, is proposed to evaluate the long-term efficacy of the RY program, and to provide for a detailed quantitative analysis of the theoretical underpinnings of the intervention. The latter directly addresses how the specified intervention components act to achieve the desired outcomes (reduced drug involvement and increased mood management and school performance). Analyses also provide detailed evaluation of how characteristics of the RY intervention mechanisms and group characteristics influence the experimental outcomes. Finally, a detailed quantitative and qualitative analysis, based on a re-sampling of 100 individuals for in-depth interviews, explores categories of youth who were successful or who failed to achieve the desired outcomes, particularly with respect to drug involvement. The study should inform the specificity and efficacy of the RY intervention and promote, more generally, prevention sciences' ability to understand what components of intervention strategies are successful in obtaining reductions in drug involvement and related co-occurring problem behaviors.
