Medical decision-making with tables and graphs: The role of cognition, emotions, and analytic thinking

The shift from one-way to two-way communication in healthcare decision-making has heightened the need to understand the role of display formats including tables and graphs as decision aids. In this paper, we investigate cognitive and affective influences on decision-making involving display formats. We find that a display format's impact on decision quality is mediated by two distinct components of cognition (verbatim and gist knowledge), and that tables compared to bar graphs improve decision quality. We also find evidence that analytic thinking and lower negative affect can improve decision quality. Implications for marketers, better engaging patients, and encouraging improved decision-making are discussed.

The Effectiveness of Nonprescription Drug Labels in the United States: Insights from Recent Research and Opportunities for the Future

Despite providing a consistent and comprehensible format for over-the-counter (OTC) drug communication, research suggests important limitations in the communication effectiveness of the Drug Facts Label required on OTC drugs in the United States. This literature is reviewed and some of these critical limitations of the Drug Facts Label (DFL) highlighted. These include difficulty communicating complex information that requires integration of multiple pieces of label information and limited adaptability to serve the unique needs of individual populations (e.g., low literacy or older consumers). Potential ways to improve the DFL's communication effectiveness are identified along with complementary opportunities to improve OTC drug communication by leveraging the role of pharmacists and use of adjunctive technologies.

The influence of need for cognition and principal display panel factors on over-the-counter drug facts label comprehension

Nearly all work aimed at optimizing the ability of labeling to communicate over-the-counter (OTC) drug information has focused on back-of-the-package characteristics, such as the Drug Facts label. The effects of front of the package, or principal display panel (PDP) factors, have largely been neglected by researchers. Similarly, heterogeneity in consumers' approach to new information has received scant attention in the context of OTC drugs. This preliminary study tested the hypothesis that display of a drug's brand name on the PDP and individuals' need for cognition influence comprehension of Drug Facts label information. University students (n = 212) that had experienced heartburn but not used the drug class being studied constituted the primary analysis cohort. Students were randomly assigned to review one of two PDPs (brand name or generic), followed by a Drug Facts label and a series of questions related to selection and usage of the drug. Participants with low need for cognition were influenced by the brand name PDP, as those exposed to a PDP featuring a brand (vs. generic) spent less time reading the Drug Facts label and demonstrated lower comprehension of the label information on proper drug selection. These findings suggest that further research is needed to understand the impact of PDP contents and cognitive characteristics of consumers on the communication of OTC drug information. Health care providers should consider communication strategies that account for the challenges patients face in using OTC drugs properly.
