To determine whether providing corrective health information can reduce the tendency of consumers to believe that the implied marketing message that two "potentially reduced exposure products" (PREPs) are safer than regular cigarettes.
Face-to-face interviews with smokers assigned to one of four conditions, which varied in terms of the presence or absence of health information that qualified claims made in advertising for two PREPs.
A convenience sample of 177 smokers in Boston area.
Health information detailed the extent to which exposure to toxins and health risks of the brands were unknown.
Respondents' assessments of the health risks and toxicity of the two combustible PREPs, Advance and Eclipse.
The health information had a modest but significant effect on ratings of health risk, and reduced perceptions that switching to the new brands would lower a smoker's risk of cancer (OR 0.75; p<0.05). The health information had no effect on perceptions of toxicity.
A small dose of corrective information was effective in tempering smokers' perceptions. A higher dose of public health campaigns would be needed to affect misperceptions likely to follow a full-scale tobacco marketing effort.
确定提供纠正性健康信息是否能降低消费者认为两种“潜在低暴露产品”(PREPs)比普通香烟更安全这一隐含营销信息的倾向。
对被分配到四种情况之一的吸烟者进行面对面访谈,这四种情况在是否存在使两种PREPs广告中的声明具有资格的健康信息方面有所不同。
波士顿地区177名吸烟者的便利样本。
健康信息详细说明了品牌接触毒素的程度和健康风险未知的情况。
受访者对两种可燃PREPs(Advance和Eclipse)的健康风险和毒性的评估。
健康信息对健康风险评级有适度但显著的影响,并降低了认为改用新品牌会降低吸烟者患癌风险的认知(比值比0.75;p<0.05)。健康信息对毒性认知没有影响。
小剂量的纠正性信息有效地缓和了吸烟者的认知。需要更高剂量的公共卫生运动来影响可能伴随全面烟草营销努力而产生的误解。
