Abstract

The appropriate use of pharmaceuticals, as well as their hazards, are not commonly known to most people. In fact, the only information available to consumers at the time of consumption is usually the material found on the product label. Unfortunately, people often have difficulty with the labels because the print on the label is too small for them to read. Two alternative (tag and fold-out) designs were developed to increase the available surface area on a fictitious prescription drug label. The alternative label designs, with and without pictorials depicting instructions and warnings, were compared to a standard control label. In Expt. l, 84 undergraduates rated the labels on several preference dimensions, including: ease of reading the labels, likelihood of noticing the warnings, likelihood of reading the warnings, preference for each of the labels, and likelihood that they would recommend each label for use by a friend or family member. Across all dimensions, undergraduates preferred the alternative labels, especially the tag labels, and labels with pictorials. In Expt. 2, the ratings of 58 older adults (mean age = 73 years) showed a similar pattern of results. Implications of these results and recommendations for future research in this area are discussed.

    In particular, Boelhouwer, Davis, Franco-Watkins, Dorris, and Lungu (2013) showed that the addition of pictograms to safety data sheets and product labels may improve the communication of safety information for both naïve and expert users. Dowse and Ehlers (2005) found that incorporating pictograms on medicine labels contribute positively to both understanding and adherence to safety rules, and in their study on pharmaceutical labels, Kalsher, Wogalter, and Racicot (1996) found that both undergraduates and older adults preferred labels with pictograms. However, different studies have reported that many pictograms currently in use are poorly understood (Duarte & Rebelo, 2005; Liu, Zhong, & Xing, 2005; Rubbiani, 2010).
