Using a multiple baseline design, this study examined the effect of preferred items in increasing medication knowledge among individuals diagnosed with a mental illness. Participants were asked questions regarding their Haldol medication. After baseline, participants received the answers and a pharmacy-generated medication profile. During the Repeated Trials intervention, participants were given only verbal feedback. Those who had not reached criterion after 4 weeks entered the Preferred Trials intervention. In this phase, participants received a high, medium, or low preferred item contingent on the number of correct answers. All participants increased their number of correct answers. Although the effects of a contingent preferred item were mixed, this study showed that information regarding medications can be learned with minimal staff intervention.
