OBJECTIVE
Drug efficacy can be measured by composite scores, which consist of two or more symptoms or other clinical components of a disease. We evaluated how individuals interpret composite scores in direct-to-consumer (DTC) prescription drug advertising.
METHODS
We conducted an experimental study of seasonal allergy sufferers (n=1967) who viewed a fictitious print DTC ad that varied by the type of information featured (general indication, list of symptoms, or definition of composite scores) and the presence or absence of an educational intervention about composite scores. We measured composite score recognition and comprehension, and perceived drug efficacy and risk.
RESULTS
Ads that featured either (1) the composite score definition alone or (2) the list of symptoms or general indication information along with the educational intervention improved composite score comprehension. Ads that included the composite score definition or the educational intervention led to lower confidence in the drug's benefits. The composite score definition improved composite score recognition and lowered drug risk perceptions.
CONCLUSION
Adding composite score information to DTC print ads may improve individuals' comprehension of composite scores and affect their perceptions of the drug.
PRACTICE IMPLICATIONS
Providing composite score information may lead to more informed patient-provider prescription drug decisions.
目的
药物疗效可通过综合评分来衡量，综合评分由疾病的两种或更多症状或其他临床成分组成。我们评估了个体如何解读直接面向消费者（DTC）的处方药广告中的综合评分。
方法
我们对季节性过敏患者（n = 1967）进行了一项实验研究，这些患者观看了一则虚构的印刷DTC广告，该广告因所展示信息的类型（一般适应症、症状列表或综合评分的定义）以及是否存在关于综合评分的教育干预而有所不同。我们测量了综合评分的识别和理解，以及对药物疗效和风险的认知。
结果
（1）仅包含综合评分定义的广告，或（2）包含症状列表或一般适应症信息以及教育干预的广告，提高了综合评分的理解。包含综合评分定义或教育干预的广告导致对药物益处的信心降低。综合评分定义提高了综合评分的识别，并降低了对药物风险的认知。
结论
在DTC印刷广告中添加综合评分信息可能会提高个体对综合评分的理解，并影响他们对药物的认知。
实践意义
提供综合评分信息可能会使患者和医生在处方药决策时更加明智。
