Creating Persuasive Messages Advocating Organ Donation

Most people state that they would be willing to be organ donors, however only a small percentage of the population has actually signed an organ donor card. These studies focused on persuasive messages that encourage people to sign organ donor cards. In the first study, people reported their attitudes and knowledge involving organ donation. Results indicated that donor card signing was related to overall knowledge about donation. When only considering those people with positive attitudes toward organ donation, their overall knowledge about donation explained their willingness to sign organ donor cards. In the second study, people read a message involving organ donation before they were asked to sign an organ donor card. The content of the message (i.e., narrative vs. statistics) and the affect of the message (i.e., humorous vs. sad) were manipulated. Results indicated that narrative messages were more effective than statistical messages. Additionally, humorous messages were more effective than sad messages.
