MASS MEDIA AND PREVENTION OF ADOLESCENT SMOKING

本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， 青少年。 这些运动以行为科学理论为指导， 前提是他们应该是成本效益，重点放在后果 预期从吸烟行为和同伴参与的刺激。 美国东南部标准大都市统计区（SMSA） 如果居民少于50万，将随机分配10人， 接受反映强度和成本增量的治疗：1.四 SMS将不会接收活动（控件），2.两个将接收无线电 这些信息侧重于选定的吸烟预期后果， 吸烟，3。两个将接收无线电信息，另一个将 促进同伴参与; 4.两个将接收消息并对等 通过广播和电视参与。 基线数据将是 收集了223名青少年和他们的母亲在每个SMSA之前， 为期六个月的大众媒体宣传活动。 吸烟行为，预期后果 将测量该行为的前因变量和中介变量。 运动一年后，这些措施将重复， 科目 每个SMSA中50例受试者子样本的中期测量 将在运动结束后一个月内进行评估， 并提供对早期活动影响的估计。 在 除了实验组和对照组的比较， 分析将确定活动效果是否会因 根据中介变量。 研究结果将在 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.
