以学校为基础的毒品预防课程是国家预防青少年吸毒的最普遍战略。我们评估了一个这样的课程，项目ALERT，对青少年物质使用的影响。特别是，我们试图确定是否可以在1年后检测到对30天酒精使用的单一影响，即在2年计划完成后不久注意到的影响。我们还研究了对其他感兴趣结果的延迟效应，即终生饮酒，以及30天和终生使用香烟，大麻和吸入剂。我们采用随机对照试验，以学校为单位的分配。来自11个州的34所6-8年级的学校完成了这项研究。71名ALERT项目教师向六年级学生讲授了11门核心课程，向七年级学生讲授了3门助推课程。在干预开始之前，作为六年级学生，在完成2年的课程之后，作为七年级学生，并在一年后再次作为八年级学生对学生进行评估。本文对前测和后测的数据进行了检验。使用分层非线性模型，我们发现我们对30天酒精使用的早期影响并没有持续下去。此外，我们继续发现终生饮酒以及终生和30天使用香烟，大麻和吸入剂没有影响。我们的研究结果不支持项目ALERT的长期有效性，当交付给六年级学生。
School-based drug prevention curricula constitute the nation's most prevalent strategy to prevent adolescent drug use. We evaluated the effects of one such curriculum, Project ALERT, on adolescent substance use. In particular, we sought to determine if a single effect on 30-day alcohol use, noted shortly following the completion of the 2-year program, could be detected 1 year later. We also looked for delayed effects on other outcomes of interest, namely lifetime alcohol use, and 30-day and lifetime use of cigarettes, marijuana, and inhalants. We employed a randomized controlled trial that used school as the unit of assignment. Thirty-four schools with grades 6-8 from 11 states completed the study. Seventy-one Project ALERT instructors taught 11 core lessons to sixth graders and 3 booster lessons to seventh graders. Students were assessed prior to the onset of the intervention, as sixth graders, after the completion of the 2-year curriculum, as seventh graders, and again 1 year later as eighth graders. This paper examines data from the pretest and final posttest. Using hierarchical nonlinear modeling, we found that our earlier effect on 30-day alcohol use did not persist. Further, we continued to find no effects for lifetime alcohol use and both the lifetime and 30-day use of cigarettes, marijuana, and inhalants. Our findings do not support the long-term effectiveness of Project ALERT, when delivered to sixth graders.
