Brief Integrative Alcohol Interventions for Adolescents

描述(由申请人提供)：这项修订的竞争延续申请的主要目的是测试创新的简短酒精滥用预防策略的有效性，这些策略的形式包括人际咨询(咨询)、家长沟通(家长)和综合策略(综合)，这些策略将积极的青年发展信息和对不同高中环境中使用药物的青少年的健康风险信息结合在一起。第二个目标是以不同的组合检查这些策略，作为干预和再干预(即助推器)，以维持或增强随时间推移的行为改变效果。这些策略是建立在一个名为行为-图像模型的新兴概念框架上的，该框架源于我们最近对多种健康行为干预结果进行的试验结果。该项目的长期目标是减少酒精滥用和老年高危青少年中的问题，这些青少年目前正在使用酒精或其他药物，但在预防研究和服务中往往被忽视。我们建议进行初步的形成研究阶段，然后是两个单独的试验阶段。第一项试验是一项随机先导性研究，旨在评估两种增强策略(咨询与家长)和组合策略(咨询+家长)的可行性和有效性，该策略构成了针对青少年使用高危物质的第二代综合性、多行为预防干预项目SPORT II。第二个试验是对来自不同高中环境(包括城市、郊区和农村)的使用物质的青少年进行随机纵向评估，评估作为初始干预措施的策略以及使用各种组合的再干预措施的效果、成本和成本效益。我们还将研究作用机制，看看预防性干预对饮酒的任何影响，包括目前的饮酒、过度饮酒和与酒精相关的问题，以及对锻炼习惯和吸烟和大麻使用的影响，是否受到各种基于理论的认知、社会和环境风险和保护因素的调节。

DESCRIPTION (provided by applicant): The primary aim of this revised competing continuation application is to test the efficacy of innovative, brief alcohol abuse prevention strategies in the form of an interpersonal consultation (Consult), parent communication (Parent), and combined strategy (Combined), which integrate positive youth development messages and health risk messages for substance using adolescents in diverse high school settings. A secondary aim is to examine these strategies in various combinations as interventions and re-interventions (i.e., boosters) for sustaining or enhancing behavior change effects over time. These strategies are founded upon an emerging conceptual framework titled the Behavior-Image Model emanating from findings of our recent trials examining multiple health behavior intervention outcomes. The long-term objective of this project is to reduce alcohol abuse and problems among older high-risk adolescents who currently use alcohol or other drugs, but are often ignored in prevention research and services. We propose to conduct an initial formative research phase, followed by two separate trial phases. The first trial is a randomized pilot study to evaluate the feasibility and efficacy of two enhanced strategies (Consult vs. Parent) and a Combined strategy (Consult plus Parent) constituting the second generation integrative, multiple behavior preventive intervention Project SPORT II for high-risk substance using adolescents. The second trial is a randomized longitudinal evaluation of the effects, cost, and cost-effectiveness of the strategies as initial interventions, as well as re-interventions using various combinations, among substance using adolescents from diverse high school environments, including urban, suburban, and rural settings. We will also examine mechanisms of action to see whether any effects of the preventive intervention on alcohol consumption, including current use, heavy use, and alcohol-related problems, as well as on exercise habits and cigarette and marijuana use, were mediated by various theory-based cognitive, social, and environmental risk and protective factors.
