Studies suggest that exposure to televised electronic cigarette (e-cigarette) advertising contributes to the recent increase in e-cigarette use among youth. This study examines the relationship between perceptions of e-cigarette advertisements and attitudes toward and intentions to use e-cigarettes among youth who had never used e-cigarettes.
In May 2014, we conducted an online survey of 5020 youth aged 13 to 17. Participants were randomly assigned to answer questions about their attitudes toward and intentions to use e-cigarettes before or after viewing e-cigarette advertisements. Perceived effectiveness (PE) of advertisements was measured after ad exposure. Ordinary least squares models were used to assess the relationship between PE and study outcomes.
Among never e-cigarette users, greater PE was associated with more positive attitudes toward e-cigarettes (b = 0.74, P < .001) and intentions to use e-cigarettes (b = 0.16, P < .001). Findings suggest that PE is predictive of outcomes controlling for study condition, youth demographics, and media use variables.
After ad exposure, youth who have never used e-cigarettes previously perceive e-cigarettes as cooler, more fun, healthier, and more enjoyable. Youth who thought the ads were more effective were more likely to have a positive attitude toward e-cigarettes and greater intention to try e-cigarettes in the future. Restricting televised e-cigarette advertising may reduce e-cigarette initiation among youth.
Previous studies demonstrate that, among adults, PE is antecedent to actual ad effectiveness across a range of behaviors. To our knowledge, this is the first study to document the relationship between PE and advertising effectiveness among youth. It provides evidence that PE may be a useful tool to quantify the potential influence of advertising on youth-advertising that, in this case, is designed to market a consumer good that may be harmful to youth but that may also be used to develop public health campaigns.
研究表明,接触电视电子烟广告是近期青少年电子烟使用量增加的原因之一。本研究探讨了从未使用过电子烟的青少年对电子烟广告的认知与对使用电子烟的态度及意图之间的关系。
2014年5月,我们对5020名13至17岁的青少年进行了一项在线调查。参与者被随机分配在观看电子烟广告之前或之后回答有关他们对使用电子烟的态度和意图的问题。广告曝光后测量广告的感知效果(PE)。使用普通最小二乘法模型评估PE与研究结果之间的关系。
在从未使用过电子烟的人群中,较高的PE与对电子烟更积极的态度(b = 0.74,P <.001)和使用电子烟的意图(b = 0.16,P <.001)相关。研究结果表明,PE可预测在控制研究条件、青少年人口统计学和媒体使用变量后的结果。
广告曝光后,从未使用过电子烟的青少年认为电子烟更酷、更有趣、更健康、更令人愉悦。认为广告更有效的青少年对电子烟更可能持积极态度,并且未来尝试电子烟的意愿更强。限制电视电子烟广告可能会减少青少年开始使用电子烟的情况。
先前的研究表明,在成年人中,PE是一系列行为中实际广告效果的前提。据我们所知,这是第一项记录青少年中PE与广告效果之间关系的研究。它提供了证据表明,PE可能是量化广告对青少年潜在影响的有用工具——在这种情况下,广告旨在推销一种可能对青少年有害但也可用于开展公共卫生运动的消费品。
