The present study tested the efficacy of motivational interviewing-based booster sessions for Project Toward No Drug Abuse (TND), a 12-session school-based curriculum targeting youth at risk for drug abuse. In addition, generalization of effects to risky sexual behavior was assessed. The 1-year outcomes evaluation of the project is presented.
A total of 24 schools were randomized to one of three conditions: standard care control (SCC), TND classroom program only (TND-only), and TND plus motivational interviewing booster (TND + MI). A total of 1186 participants completed baseline and 1-year follow-up surveys. Following the classroom program, youth in the TND + MI condition received up to 3 sessions of MI in person or by telephone. Effects were examined on 30-day cigarette, alcohol, marijuana, and hard drug use, as well as measures of risky sexual behavior (number of sex partners, condom use, having sex while using drugs or alcohol).
Collapsed across the 2 program conditions, results showed significant reductions in alcohol use, hard drug use, and cigarette smoking relative to controls. These effects held for an overall substance use index. The MI booster component failed to achieve significant incremental effects above and beyond the TND classroom program. No effects were found on risky sexual behavior.
While the program effects of previous studies were replicated, the study failed to demonstrate that an adequately implemented MI booster was of incremental value at 1-year follow-up.
本研究检验了基于动机访谈的强化课程对“远离毒品计划”（TND）的疗效，该课程是一项针对有药物滥用风险的青少年的 12 节学校课程。此外，还评估了效果向危险性行为的推广。本研究呈现了该项目的 1 年结果评估。
共有 24 所学校被随机分为三种条件之一：标准护理对照组（SCC）、仅 TND 课堂项目组（TND-only）和 TND 加动机访谈强化组（TND + MI）。共有 1186 名参与者完成了基线和 1 年随访调查。在课堂项目之后，TND + MI 条件下的青少年接受了多达 3 次面对面或电话进行的动机访谈。研究考察了 30 天内吸烟、饮酒、大麻和硬毒品使用情况，以及危险性行为的衡量指标（性伴侣数量、使用避孕套、在使用毒品或酒精时发生性行为）。
综合两个项目条件的结果显示，与对照组相比，酒精使用、硬毒品使用和吸烟量均显著减少。这些效果适用于整体物质使用指数。动机访谈强化组件未能在 TND 课堂项目之外产生显著的附加效果。在危险性行为方面没有发现效果。
虽然之前研究的项目效果得到了复制，但本研究未能证明充分实施的动机访谈强化在 1 年随访时具有额外的增量价值。
