Environment Alcohol Abuse Prevention--Drug Abuse Effect

描述（申请人提供）：0 大麻和其他非法药物使用与酒精和烟草的共同发生模式已经确立。 尽管如此&尽管有证据表明酒精和烟草可能成为非法物质使用的入门药物，但人们对预防计划对各种物质的影响知之甚少。具体来说，我们不知道是否有年轻人接触到成功的酒精滥用预防计划的药物使用下降，或者是否受这些计划影响的年轻人转向药物时，酒精变得更难获得和更难接受。这项研究测试了大麻和其他药物使用模式是否在大学青年中下降，这些青年暴露于成功的环境酒精滥用预防计划，减少了消费和危害。具体目标是：1）描述大麻，非法药物使用的趋势，以及参与社区范围内4年环境酒精滥用预防计划的10所大学的学生中大麻使用的获取或摄取; 2）比较10所干预学生中大麻和其他非法药物使用的趋势与32所比较大学; 3）评估那些学生报告随着时间的推移毒品使用显著下降的大学是否是那些酒精使用和危害显著下降的大学; 4）评估非法药物使用的下降是否与针对酒精滥用和危害实施的环境与个人导向的预防策略相对应。重复测量面板数据来自哈佛大学酒精研究和哈佛公共卫生学院学位项目评估，该项目在参与国家阿莫德示范的10所CAS学院进行了密集的行为监测研究，并收集了有关其酒精相关预防工作的观察数据。纵向多站点设计是单机构和/或横断面研究的一个重大进步，并有望扩大我们对影响大学青年药物使用的因果过程和保护机制的理解，以改善这种情况下的预防。

DESCRIPTION (provided by applicant):0 Co-occurring patterns of marijuana & other illicit drug use with alcohol & tobacco are well established. Despite this & despite evidence that alcohol & tobacco may serve as gateway drugs for illicit substance use little is known about the impacts of prevention programs across substances. Specifically, we do not know whether there are declines in drug use among young people exposed to successful alcohol abuse prevention programs or alternatively whether young people affected by such programs turn toward drugs when alcohol becomes harder to obtain & less acceptable. This study tests whether patterns of marijuana & other drug use decline among college youth exposed to a successful environmental alcohol abuse prevention program that has reduced consumption & harm. Specific aims are to: 1) Describe trends in marijuana, illicit drug use, & acquisition or uptake of marijuana use among students from 10 colleges that participated in a community wide 4 year environmental alcohol abuse prevention program; 2) Compare trends in marijuana & other illicit drug use among students at 10 intervention with 32 comparison colleges; 3) Evaluate whether colleges whose students report significant declines in drug use over time are those with significant declines in alcohol use & harms; 4) Assess whether declines in illicit drug use correspond to exposure to environmental versus individually oriented prevention strategies implemented for alcohol abuse & harms. Repeated measure panel data are drawn from the Harvard College Alcohol Study and Harvard School of Public Health A Matter of Degree program evaluation which conducts intensive behavioral surveillance studies at 10 CAS colleges participating in the national AMOD demonstration & collects observational data about their alcohol-related prevention efforts. The longitudinal multi-site design is a significant advance over single institution and/or cross-sectional studies, & promises to expand our understanding about causal processes & protective mechanisms affecting drug use among college youth to improve prevention in this setting.
