The present study provides an implementation fidelity, process, and immediate outcomes evaluation of Project Towards No Drug Abuse (TND), a drug prevention program targeting continuation high school youth (n=1426) at risk for drug abuse. A total of 24 schools participated in three randomized conditions: TND Only, TND and motivational interviewing follow-up, and no treatment control. Fidelity was high: across program schools the curriculum was implemented as intended and was received favorably by students. Relative to controls, intervention conditions produced effects on hypothesized mediators, including greater gains in program related knowledge, greater reductions in drug use intentions, and positive changes in motivation. However, few generalizations to attitudes and intentions regarding risky sexual behavior were found. The pattern of results suggests that the experimental manipulations worked as intended.
本研究对“无药物滥用计划”（TND）进行了实施保真度、过程及即时结果评估。该计划是一项针对有药物滥用风险的延续高中青年（n = 1426）的药物预防项目。共有24所学校参与了三种随机分组情况：仅TND组、TND与动机性访谈随访组以及无治疗对照组。保真度很高：在所有参与项目的学校中，课程均按预期实施，并受到学生好评。相对于对照组，干预组对假设的中介变量产生了影响，包括与项目相关知识的更大提升、药物使用意图的更大降低以及动机的积极变化。然而，在对危险性行为的态度和意图方面几乎没有发现普遍规律。结果模式表明实验操作按预期发挥了作用。
