Prevention of Adolescent Driving Under the Influence

该项目的目的是调查以学校和社区为基础的毒品预防计划的有效性，该计划名为MVP(中西部预防项目)，在减少青少年酒后驾车(DUI)和与司机酒后驾车(RWDUI)方面的有效性。MPP是一项以社会影响力为基础的初级预防计划，旨在改变与青少年使用毒品(烟草、酒精和大麻)有关的因素。MPP计划自1984年以来在堪萨斯州堪萨斯城和密苏里州堪萨斯城实施了6年，自1987年以来在印第安纳州印第安纳波利斯复制。堪萨斯城的42所初中和初中以及印第安纳波利斯的57所学校参与了该项目。无论是纵向研究还是横向研究，都对参与者进行了测量。根据纵向数据，堪萨斯城的1335名学生和印第安纳波利斯的2519名学生平均每年接受跟踪调查。在横断面数据收集方面，堪萨斯城平均每年有6373名学生进行测量，印第安纳波利斯平均有6067名学生接受测量。先前对MPP计划在减少青少年入门药物使用方面的效果进行的研究表明，在短期和长期的后续评估中，吸烟的成功减少，大麻使用的相似减少，酒精使用的减少较小。本项目建议评估MPP计划在减少青少年酒后驾车和RWDUI方面的效果，进行中介分析以确定MPP计划如何可能减少DUI和RWDUI，进行适度分析以确定该计划最有效或最不有效的亚群，并调查青少年DUI和RWDUI的病因，以确定这些行为的前驱因素。包括潜在增长模型、混合模型、多水平模型、缺失数据模型和处理数据非正态分布的广义线性模型在内的高级统计方法将跨多个波应用。此外，将使用更常见的统计方法从这些数据中提取最多的信息。一个项目站点的调查结果将在另一个站点交叉验证。

The purpose of this project is to investigate the effectiveness of a school- and community-based drug prevention program, entitled MVP (Midwestern Prevention Project), in reducing adolescent driving under the influence (DUI) and riding with a driver under the influence (RWDUI). MPP is a social influence-based primary prevention program aimed at modifying the factors related to adolescent gateway drug (tobacco, alcohol, and marijuana) use. The MPP programs were implemented in Kansas City, Kansas, and Kansas City, Missouri, for six years since 1984 and replicated in Indianapolis, Indiana, since 1987. Forty-two middle and junior high schools in Kansas City and 57 schools in Indianapolis participated in the project. The participants were measured either for the longitudinal study or for the cross- sectional study. On average, 1,335 students in Kansas City and 2,519 students in Indianapolis were followed-up each year providing the longitudinal data. For the cross-sectional data collection, an average of 6,373 students in Kansas City and an average of 6,067 students in Indianapolis were measured each year. Prior studies examining the MPP program effects in reducing adolescents' gateway drug use showed successful reduction in smoking, similar reduction in marijuana use, and smaller reduction in alcohol use at both short-term and long-term follow-up assessments. The present project proposes to evaluate the MPP program effects in reducing adolescent DUI and RWDUI, to conduct mediation analysis to determine how the MPP program may have reduced DUI and RWDUI, to conduct moderation analysis to identify subgroups where the program is most or least effective, and to investigate etiology of adolescent DUI and RWDUI to identify the precursors to these behaviors. Advanced statistical methods including latent growth models, mixture models, multilevel models, missing data models, and generalized linear models handling non-normality of data will be applied across multiple waves. In addition, more common statistical methods will be used to extract the maximum information from these data The findings in one project site will be cross-validated in the other site.
