title: Do Prescription Drug Ads Tell Consumers Enough About Benefits and Side Effects? Results From the Health Information National Trends Survey, Fourth Administration.
abstract: Direct-to-consumer prescription drug advertising (DTCA) is a major source of consumer information about prescription drugs. The present study updates 2002 U.S. Food and Drug Administration phone survey questions that found that 44% and 61% of consumers thought that DTCA did not include enough information about benefits and risks, respectively. The present study was administered by mail using a nationally representative sample, and provides a more in-depth understanding of how these beliefs relate to demographic and health characteristics. Data collected from 3,959 respondents to the National Cancer Institute's 2011 Health Information National Trends Survey find results similar to the 2002 survey: 46% and 52% of respondents thought that DCTA did not include enough information about benefits and risks, respectively. Respondents fell into four groups: 23% agreed that DTCA tells enough about drug benefits and risks, 41% disagreed, 18% expressed no opinion, and 18% had discordant beliefs. DTCA attitudes were negatively associated with education, income, and whether respondents purchase prescription drugs; attitudes were positively associated with whether respondents understand prescription drug information. This study confirms that a plurality of Americans believe that DTCA does not include enough information about benefits and risks, suggesting that the educational effect of DTCA could be improved.
