Considerable attention has been afforded to analyzing the content of and assessing consumers' reaction to print direct-to-consumer drug ads, but not so for televised ads.
To determine whether advertisements with different risk severity and risk presentation would significantly affect viewers' (1) recall of information contained in the advertisement, (2) evaluation of the advertisement, and (3) perceptions of the advertised product's risks.
Data were collected from a sample of 135 first-year pharmacy students at a Midwestern college of pharmacy. After viewing 1 of the 6 advertisements designed for this study, participants were asked to complete a self-administered survey. Chi-square and analysis of variance were used to analyze the data. A 2x3 between subjects design was used to test the effects of 2 levels of risk severity (high- vs low-risk severity) and 3 levels of risk presentation (original ad containing integrated risk message, deintegrated risk message/dual modality using male voice-over, deintegrated risk message/dual modality using female voice-over).
Results of analysis of variance procedures revealed that deintegrating risk information by placing it at the end of the advertisement and the use of captions in addition to oral messages (dual modality) (1) improved the recall of general and specific side effect information, (2) led to a perception that the advertisement had greater informational content, (3) resulted in lower Advertisement Distraction, and (4) lessened cognitive and affective aspects of information overload for the advertisement containing the high-risk severity medication. However, this pattern of findings was not found for the low-risk severity medication.
Alternative methods for presenting risk information in direct-to-consumer ads affected some aspects of information recall and advertisement evaluation, but were not shown to affect risk perceptions regarding the advertised products.
分析印刷品直接面向消费者的药品广告内容并评估消费者对其的反应已受到相当多关注,但电视广告方面却并非如此。
确定具有不同风险严重程度和风险呈现方式的广告是否会显著影响观众:(1)对广告中所含信息的回忆;(2)对广告的评价;(3)对所宣传产品风险的认知。
从一所中西部药学院的135名一年级药学专业学生样本中收集数据。观看为本研究设计的6则广告中的1则后,参与者被要求完成一份自我管理的调查问卷。使用卡方检验和方差分析来分析数据。采用2×3被试间设计来测试2个风险严重程度水平(高风险严重程度与低风险严重程度)和3个风险呈现方式水平(包含整合风险信息的原始广告、使用男性画外音的分离风险信息/双模态、使用女性画外音的分离风险信息/双模态)的效果。
方差分析程序的结果显示,通过将风险信息置于广告末尾进行分离以及除口头信息外使用字幕(双模态):(1)提高了对一般和特定副作用信息的回忆;(2)使人们认为广告具有更多信息内容;(3)降低了广告干扰度;(4)减轻了包含高风险严重程度药物广告的信息过载在认知和情感方面的影响。然而,对于低风险严重程度药物,未发现这种结果模式。
在直接面向消费者的广告中呈现风险信息的替代方法影响了信息回忆和广告评价的某些方面,但未显示会影响对所宣传产品的风险认知。
