RANDOMIZED TRIAL OF A STAGE-BASED PRIMARY CARE PROGRAM

本研究的主要目的是测试 针对高危青年的酒精滥用预防战略 初级卫生保健设施。这些预防战略将基于 创新的多成分动机阶段（McMOS）理论 模型具体来说，我们建议评估三种药物的疗效- 名为STARS计划（开始服用 酒精危害严重）。这种干预将涉及：1）青年自我- 教学模块和相应的录音带; 2）简要的健康 医生和护士提供的咨询;和3）[6] 护士提供的后续咨询。 本研究将采用实验设计来测试 建议进行初级卫生保健干预。本研究旨在 审查可复制的、以卫生保健为基础的预防战略。主 将审查的结果措施包括酒精消费模式， 酒精使用的获得和改变的阶段。中学，中介 结果指标将包括其他药物的使用，包括 香烟、无烟烟草、大麻和可卡因;使用频率 避免饮酒的自我控制策略;认知 社会因素包括期望信念、自我效能、 影响力感知的使用流行度，以及使用意图;以及 与酒精有关的健康信念和避免饮酒的动机。 短期（3个月）、中期（1年）和长期（2年）结局 将确定预防战略。纵向研究 在青少年酗酒问题上， 预防滥用（Coodstadt，1986年;汉森，1992年;莫斯科维茨，1989年）。的 拟议的两年后续行动将提供以下方面的宝贵信息： 干预成分的潜在长期持续影响， 和时间的作用，各种成因的运动， 青少年通过酒精使用的获得和改变的阶段。

The primary purpose of this research is to test the effectiveness of alcohol abuse prevention strategies targeting high-risk youth in a primary health care setting. These prevention strategies will be based on an innovative Multi-Component Motivational Stages (McMOS) theoretical model. Specifically, we propose to evaluate the efficacy of a three- component prevention intervention titled the STARS program (Start Taking Alcohol Risks Seriously). This intervention will involve: 1) youth Self- Instructional Modules and corresponding audio-tapes; 2) brief Health Consultations provided by physicians and nurses; and 3) [six Extended Follow-Up Consultations provided by nurses.] This study will employ an experimental design to test the effects of the proposed primary health care intervention. This study is designed to examine replicable, health care-based prevention strategies. The primary outcome measures to be examined include alcohol consumption patterns, and the stages of alcohol use acquisition and change. Secondary, mediating outcome measures will include the use of other drugs including cigarettes, smokeless tobacco, marijuana and cocaine; frequency of use of self-control strategies for avoiding alcohol consumption; cognitive and social factors including expectancy beliefs, self-efficacy, influenceability perceived prevalence of use, and intentions to use; and alcohol-related health beliefs and motivation to avoid alcohol use. Short-term (3 months), mid-term (1 year) and long-term (2 year) outcomes will be determined for the prevention strategies. Longitudinal studies such as the one proposed are much needed in the area of youth alcohol abuse prevention (Coodstadt, 1986; Hansen, 1992; Moskowitz, 1989). The proposed two year follow-up will provide invaluable information regarding the potential long-term sustained effects of the intervention components, and the temporal role of various causative factors in the movement of youth through the stages of alcohol use acquisition and change.
