Drug manufacturers are intensely promoting their products directly to consumers, but the impact has not been widely studied. Consumers' awareness and understanding of, attitudes toward, and susceptibility to direct-to-consumer (DTC) drug advertising were examined.
Random-digit dialing telephone survey with a random household member selection procedure (completion and response rates, 58% and 69%, respectively).
Respondents were interviewed while they were at their residences.
Complete data were obtained from 329 adults in Sacramento County, California.
Outcome measures included awareness of advertisements for 10 selected drugs, misconceptions about DTC advertising, attitudes toward DTC ads, and behavioral responses to such promotions. The influence of demographic characteristics, health status, attitudes, beliefs, and media exposure on awareness and behaviors was examined. On average, respondents were aware of advertisements for 3.7 of the 10 drugs; awareness varied from 8% for Buspar (buspirone) to 72% for Claritin (loratadine). Awareness was associated with prescription drug use, media exposure, positive attitudes toward DTC advertising, poorer health, and insurance status. Substantial misconceptions were revealed; e.g., 43% thought that only "completely safe" drugs could be advertised. Direct-to-consumer advertisements had led one third of respondents to ask their physicians for drug information and one fifth to request a prescription.
Direct-to-consumer advertisements are reaching the public, but selectively so, and affecting their behaviors. Implications for public policy are examined.
药品制造商正在大力向消费者直接推销其产品,但这种影响尚未得到广泛研究。对消费者对直接面向消费者(DTC)药品广告的知晓度、理解、态度及易感性进行了调查。
采用随机数字拨号电话调查,通过随机选择家庭成员的程序(完成率和回复率分别为58%和69%)。
在受访者家中进行访谈。
从加利福尼亚州萨克拉门托县的329名成年人中获取了完整数据。
结果指标包括对10种选定药品广告的知晓度、对DTC广告的误解、对DTC广告的态度以及对此类促销活动的行为反应。研究了人口统计学特征、健康状况、态度、信念和媒体曝光对知晓度和行为的影响。平均而言,受访者知晓10种药品中3.7种的广告;知晓度从布斯帕(丁螺环酮)的8%到开瑞坦(氯雷他定)的72%不等。知晓度与处方药使用、媒体曝光、对DTC广告的积极态度、较差的健康状况和保险状况相关。发现了大量误解;例如,43%的人认为只有“完全安全”的药品才能做广告。DTC广告导致三分之一的受访者向医生询问药品信息,五分之一的受访者要求开处方。
DTC广告正在面向公众,但具有选择性,并且正在影响他们的行为。探讨了对公共政策的影响。
