这项研究调查了一项旨在减少使用合成类固醇、改善营养和提高力量训练自我效能的计划效果的中介机制。俄勒冈州和华盛顿州的31支高中橄榄球队中的15支(N=1,506名基线球员)被分配接受干预。多组分计划涉及社会影响，促进麦角源性药物的使用，并让学生参与健康营养和力量训练的替代行为。尽管这三个因变量的结果不同，但该项目似乎通过改变团队规范来发挥作用。与其他药物的预防不同，知识的变化和感知的严重性是本研究中计划效果的中介因素。
This study investigated the mediating mechanisms responsible for the effects of a program designed to reduce intentions to use anabolic steroids, improve nutrition, and increase strength training self-efficacy. Fifteen of 31 high school football teams (N = 1,506 players at baseline) in Oregon and Washington were assigned to receive the intervention. The multicomponent program addressed the social influences promoting ergogenic drug use and engaging students in healthy nutrition and strength training alternative behaviors. Although the results differed across the three dependent variables, the program appeared to work by changing team norms. Unlike prevention of other drugs, changes in knowledge and perceived severity were mediators of program effects in this study.
