To assess the relationship between youth's exposure to the Food and Drug Administration's national tobacco public education campaign, The Real Cost, and changes in campaign-targeted beliefs.
Longitudinal design with baseline survey and 2 postcampaign follow-up surveys.
Youth from 75 US media markets (N = 1680) who completed all 3 surveys and had experimented with or were susceptible to future cigarette smoking.
Exposure was measured by self-reported frequency of ad exposure and media market-level target rating points. Agreement with 30 self-reported tobacco-related beliefs was assessed in 3 categories: (1) beliefs specifically targeted by campaign messages (campaign-targeted belief), (2) beliefs not targeted by the campaign (nontargeted beliefs), and (3) beliefs corresponding to other media campaigns on air concurrent with The Real Cost (ambiguous beliefs).
Descriptive analyses of aggregate changes in beliefs and logistic regressions to examine the association between campaign exposure and beliefs.
The Real Cost.
Agreement with campaign-targeted beliefs increased from baseline to first and second follow-ups, with a mean relative increase of 10.4% and 11.5%, respectively. Nontargeted beliefs did not change substantially. Both measures of campaign exposure were positively associated with increased odds of agreeing with 5 of 8 campaign-targeted beliefs. Exposure was not significantly associated with 12 of 14 nontargeted tobacco-related beliefs.
A sustained national tobacco public education campaign can change population-level perceptions of tobacco-related harms among youth.
评估青少年接触美国食品药品监督管理局的全国烟草公共教育活动“真实成本”与活动目标信念变化之间的关系。
采用纵向设计,包括基线调查和两次活动后的随访调查。
来自美国75个媒体市场的青少年(N = 1680),他们完成了所有三项调查,并且已经尝试吸烟或未来有吸烟倾向。
通过自我报告的广告接触频率和媒体市场层面的目标收视率来衡量接触情况。对30种自我报告的与烟草相关的信念进行评估,分为三类:(1)活动信息专门针对的信念(活动目标信念),(2)活动未针对的信念(非目标信念),以及(3)与“真实成本”同时播出的其他媒体活动相对应的信念(模糊信念)。
对信念的总体变化进行描述性分析,并进行逻辑回归分析,以检验活动接触与信念之间的关联。
“真实成本”活动。
与活动目标信念的一致性从基线到第一次和第二次随访有所增加,平均相对增加分别为10.4%和11.5%。非目标信念没有实质性变化。两种活动接触测量方法都与同意8项活动目标信念中的5项的几率增加呈正相关。接触与14项非目标烟草相关信念中的12项没有显著关联。
持续开展的全国烟草公共教育活动可以改变青少年群体对烟草相关危害的认知。
