这项研究的目的是评估质量的长期影响 旨在防止吸烟的媒体宣传活动通过 青少年。这些运动，在行为科学理论和 前提是它们应该具有成本效益，关注后果 期望来自吸烟行为和同伴参与的刺激。 来自美国东南部的标准大都会统计区(SMSA) 不到50万居民的10个将被随机分配到 接受强度和费用递增的治疗：1.4 SMSA将不会收到活动(控制)，2.两个将收到无线电 关注吸烟和不吸烟的预期后果的信息 吸烟，3.两人将收到无线电信息，外加一个组件，以 促进同伴参与，4.两个人将收到消息和同伴 通过广播和电视的参与部分。基准数据将为 收集了每个SMSA的223名青少年及其母亲的数据 六个月的大众媒体宣传活动。吸烟行为，预期的后果 以及前置变量和中介变量将被测量。 竞选活动一年后，这些措施将以同样的方式重复 研究对象。每个SMSA抽样调查50人的暂行办法 将在活动结束后一个月内进行评估，以了解 并提供对早期竞选效果的估计。在……里面 除了试验组和控制组的比较，以及比较 在试验组中，分析将确定竞选效果是否有所不同 根据中介变量。调查结果将在 预防青少年吸烟的背景。

The purpose of this research is to evaluate the long-term influence of mass media campaigns designed to prevent the initiation of cigarette smoking by adolescents. The campaigns, guided by behavioral science theory and the premise that they should be cost effective, focus on the consequences expected from smoking behavior and the stimulation of peer involvement. From Standard Metropolitan Statistical Areas (SMSAs) in the Southeast U.S. with fewer than 500,000 inhabitants, 10 will be randomly allocated to receive treatments which reflect increments in intensity and cost: 1. four SMSAs will not receive the campaign (controls), 2. two will receive radio messages which focus on selected expected consequences of smoking and not smoking, 3. two will receive the radio messages plus a component to facilitate peer involvement, and 4. two will receive the messages and peer involvement component via both radio and television. Baseline data will be collected from 223 adolescents and their mothers in each SMSA before the six month mass media campaign. Smoking behavior, the expected consequences of that behavior, and antecedent and mediator variables will be measured. One year after the campaign the measures will be repeated with the same subjects. Interim measures for a subsample of 50 subjects in each SMSA will be taken within one month after the campaign to assess awareness of the campaign and to provide estimates of early campaign effects. In addition to comparisons of experimental and control groups, and comparisons of experimental groups, analyses will determine if campaign effects vary according to mediating variables. The findings will be considered in the context of preventing the onset of adolescent smoking.
