Taking Repeated Exposure into Account: An Experimental Study of Direct-To-Consumer Prescription Drug Television Ad Effects.

Journal Article (Journal Article)

Introduction: Little is known about how repeated exposure to direct-to-consumer prescription drug promotion can impact consumers' retention and perceptions of drug information. The study described here tested the effects of varied ad exposure frequency on these outcomes. Methods: In an in-person experiment, participants with seasonal allergies (n = 616) were randomized to view a mock prescription drug television ad either once, twice, or four times within 1 h of television programming, embedded with six commercial breaks. Respondents then answered a 20-min survey administered via computer. Results: Those who viewed the ad more frequently were better able to recall both risk (X2 = 20.93, p < .001) and benefit information (X2 = 9.34, p = .009) and to recognize risk (F(2,597) = 11.89, p = .001) and benefit information (F(2,597) = 3.17, p = .043) than those who viewed the ad one time. Ad exposure frequency was not associated with perceptions about the magnitude or likelihood of risks or benefits. In general, risk information seemed to require more repetitions than benefit information to be accurately remembered. The recall was mediated by elaborate processing. Discussion: Effects on memory were small; retention of both risks and benefits remained low overall even after four exposures.
