Direct-to-consumer (DTC) television ads must disclose a drug's most important risks. Currently, the risks must be in audio at a minimum. Studies have shown that presenting information with both audio and superimposed risk text (dual-modality) improves recall beyond that of using audio alone. However, distracting elements in DTC ads may draw attention away from the superimposed risk text. This study combined eye-tracking data with questionnaire data to examine whether distracting elements decrease attention to the risk text in DTC ads, in turn affecting risk retention and risk perceptions. The authors randomly assigned 300 U.S. opt-in panel members to view either a low-distraction or a high-distraction DTC television ad. The authors found that distracting elements during risk presentation drew attention away from the risk text and, in turn, reduced retention of drug risk information. Risk perceptions were not affected. These results suggest that even if dual-modality is used to increase consumer's comprehension of drug risk information, distracting visuals should still be avoided in order to help consumers focus on key information in the ad.
直接面向消费者(DTC)的电视广告必须披露药品的最重要风险。目前,这些风险至少必须通过音频形式呈现。研究表明,同时通过音频和叠加风险文本(双模式)呈现信息,能够提高记忆效果,比仅使用音频的方式更佳。然而,DTC广告中的干扰元素可能会分散对叠加风险文本的注意力。本研究将眼动追踪数据与问卷调查数据相结合,以检验干扰元素是否会降低对DTC广告中风险文本的关注度,进而影响风险记忆和风险认知。作者随机分配300名美国选择加入的小组成员观看低干扰或高干扰的DTC电视广告。作者发现,在风险呈现过程中的干扰元素会分散对风险文本的注意力,进而降低药品风险信息的记忆。风险认知未受影响。这些结果表明,即使采用双模式来提高消费者对药品风险信息的理解,为帮助消费者专注于广告中的关键信息,仍应避免使用干扰性的视觉元素。
