Brief Integrative Alcohol Interventions for Adolescents

描述（由申请人提供）：这一修订后的竞争性继续申请的主要目的是测试以人际咨询（Consult）、父母沟通（parent）和联合策略（combined）形式的创新、简短的酒精滥用预防策略的有效性，这些策略将积极的青少年发展信息和健康风险信息整合在不同的高中环境中使用物质的青少年。第二个目的是检查这些策略作为干预和再干预（即助推器）的各种组合，以便随着时间的推移维持或增强行为改变的效果。这些策略建立在一个名为“行为-形象模型”的新兴概念框架之上，该框架源自我们最近检查多种健康行为干预结果的试验结果。该项目的长期目标是减少目前使用酒精或其他药物但在预防研究和服务中经常被忽视的年长高危青少年的酒精滥用和问题。我们建议进行一个初步的形成性研究阶段，然后是两个单独的试验阶段。第一项试验是一项随机试点研究，旨在评估两种增强策略（咨询与父母）和联合策略（咨询与父母）的可行性和有效性，这两种策略构成了第二代综合、多重行为预防干预项目SPORT II，针对使用高风险物质的青少年。第二项试验是对来自不同高中环境（包括城市、郊区和农村环境）的吸毒青少年进行的作为初始干预以及使用各种组合进行再干预的策略的效果、成本和成本效益的随机纵向评估。我们还将研究作用机制，看看预防干预对酒精消费的任何影响，包括当前使用、重度使用和酒精相关问题，以及对运动习惯、吸烟和大麻使用的影响，是否由各种基于理论的认知、社会和环境风险和保护因素介导。

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.
