DESCRIPTION: (adapted from Investigator's abstract) The purpose of this continuation proposal is to continue to complete and publish the evaluation of a prospective, randomized, study of the effects of the school-based anabolic steroid and other drug use prevention program, entitled ATLAS (Adolescents Training and Learning to Avoid Steroids). ATLAS is a social-influences based primary prevention program aimed at modifying those factors that increase the desire of young athletes to use anabolic steroids. In addition, nutrition and strength training alternatives to anabolic steroids are provided. The program uses peer leaders and coaches in a team-centered approach to exert positive peer pressure and role modeling. After one year, positive effects on self-reported steroid use, intentions to use steroids, nutrition behaviors, and many mediators of program effects were observed. 31 Portland, Oregon-area high school football teams were randomized to receive the ATLAS program (15 high schools) or a standard pamphlet on steroid use. Starting in the summer of 1994 with cohort 1, a total of four cohorts of all football players at these 31 high schools were measured for four years-- the last data collection was November, 1997. Over 4000 subjects are in this multiple wave longitudinal data set that includes questionnaire and anthropometric (e.g., height, weight, body fat, strength) measures. The data for the project were collected, cleaned and merged five months after funding for the grant expired. No new data collection is planned for this continuation proposal. We will apply recently developed statistical methods and software in the evaluation of program effects, mediation analysis to determine how the ATLAS program worked, moderator analysis to identify subgroups where the program is most or least effective, and etiological analysis to identify the precursors to steroid and other drug use. Advanced statistical methods including growth curve models, mixture models, multiple mediator models, hierarchical linear models, missing data models, and models for categorical data will be applied across multiple waves and across each of the four cohorts. The overall purpose of the grant is to use advanced as well as more common statistical methods to extract the maximum important information from these data and publish the results.

描述：（改编自研究者摘要） 继续建议继续完成和出版的评价， 一项前瞻性的随机研究，研究以学校为基础的合成代谢 名为ATLAS（青少年）类固醇和其他毒品使用预防方案 培训和学习避免使用类固醇）。ATLAS是一个基于社会影响的 一级预防计划，旨在改变那些增加 年轻运动员使用合成代谢类固醇的愿望。此外，营养和 提供了合成代谢类固醇的力量训练替代物。程序 以团队为中心的方法，使用同侪领导者和教练， 同伴压力和榜样作用。一年后，积极影响 自我报告的类固醇使用，使用类固醇的意图，营养行为，以及 观察到许多程序效应的介质。31波特兰，俄勒冈州-区域高 学校足球队被随机接受ATLAS计划（15高 学校）或类固醇使用的标准小册子。从1994年夏天开始 与队列1，总共四个队列的所有足球运动员在这些31高 学校被测量了四年--最后一次数据收集是在11月， 1997.超过4000名受试者在这个多波纵向数据集中， 包括问卷调查和人体测量（例如，身高体重体脂 强度）措施。收集、清理和合并项目数据 五个月后，资助到期。没有新的数据收集 为这一延续提案而规划。 我们将应用最近开发的统计方法和软件， 评估方案效果，调解分析，以确定如何ATLAS 程序工作，主持人分析，以确定亚组的程序是 最有效或最不有效的，和病因分析，以确定的前兆， 类固醇和其他药物使用。先进的统计方法，包括增长曲线 模型，混合模型，多中介模型，分层线性模型， 缺失数据模型和分类数据模型将应用于 多个波和跨越四个队列中的每一个。的总体目的 格兰特将使用先进的以及更常见的统计方法来提取 从这些数据中获取最重要的信息，并公布结果。
