American television viewers see as many as 16 hours of prescription drug advertisements (ads) each year, yet no research has examined how television ads attempt to influence consumers. This information is important, because ads may not meet their educational potential, possibly prompting consumers to request prescriptions that are clinically inappropriate or more expensive than equally effective alternatives.
We coded ads shown during evening news and prime time hours for factual claims they make about the target condition, how they attempt to appeal to consumers, and how they portray the medication and lifestyle behaviors in the lives of ad characters.
Most ads (82%) made some factual claims and made rational arguments (86%) for product use, but few described condition causes (26%), risk factors (26%), or prevalence (25%). Emotional appeals were almost universal (95%). No ads mentioned lifestyle change as an alternative to products, though some (19%) portrayed it as an adjunct to medication. Some ads (18%) portrayed lifestyle changes as insufficient for controlling a condition. The ads often framed medication use in terms of losing (58%) and regaining control (85%) over some aspect of life and as engendering social approval (78%). Products were frequently (58%) portrayed as a medical breakthrough.
Despite claims that ads serve an educational purpose, they provide limited information about the causes of a disease or who may be at risk; they show characters that have lost control over their social, emotional, or physical lives without the medication; and they minimize the value of health promotion through lifestyle changes. The ads have limited educational value and may oversell the benefits of drugs in ways that might conflict with promoting population health.
美国电视观众每年观看多达16小时的处方药广告,但尚无研究考察电视广告是如何试图影响消费者的。这些信息很重要,因为广告可能无法充分发挥其教育潜力,可能会促使消费者要求开具临床上不合适或比同等有效替代药物更昂贵的处方。
我们对晚间新闻和黄金时段播出的广告进行编码,分析它们对目标病症提出的事实性主张、它们试图吸引消费者的方式,以及它们如何描绘广告角色生活中的药物和生活方式行为。
大多数广告(82%)提出了一些事实性主张,并对产品使用进行了理性论证(86%),但很少描述病症原因(26%)、风险因素(26%)或患病率(25%)。情感诉求几乎无处不在(95%)。没有广告提及生活方式改变可替代产品,尽管有些广告(19%)将其描绘为药物治疗的辅助手段。一些广告(18%)将生活方式改变描绘为不足以控制病症。广告经常将药物使用描述为在生活的某些方面失去(58%)并重新获得控制(85%),以及获得社会认可(78%)。产品经常(58%)被描绘为医学突破。
尽管声称广告具有教育目的,但它们提供的关于疾病原因或哪些人可能有风险的信息有限;它们展示了没有药物就对自己的社交、情感或身体生活失去控制的角色;并且它们将通过生活方式改变促进健康的价值最小化。这些广告的教育价值有限,可能会以与促进公众健康相冲突的方式过度推销药物的益处。
