In the context of public service advertisements promoting human papillomavirus (HPV) vaccination, the current research examines 1) the relative persuasiveness of narrative vs. non-narrative messages and 2) the influence of narrative perspective (first- vs. third-person) and modality (text-based vs. audio-based) on message effectiveness. Results of a controlled experiment (N = 121) suggested that both a non-narrative message and a first-person narrative message led to greater perceived risk of getting HPV than a third-person narrative message. There was no difference in risk perception between the non-narrative and first-person narrative conditions. These findings were confined to the text-based condition, however. When the messages were audio-based, no differential message effects were detected. The analysis also provided partial evidence for an indirect effect of narrative perspective on intentions to vaccinate against HPV through HPV risk perception. Theoretical and practical implications of the findings are discussed.
Past research involving the persuasive impact of entertainment narratives on health attitudes and behavior has largely been limited to dramatic narratives. The current research focuses on humorous narratives related to unprotected sex. We conducted an experiment (N = 161) in which female viewers were exposed to a humorous story line about unprotected sex, an identical story line with humor edited out, or a story line unrelated to unprotected sex. Our findings suggested that humor increased perceived severity of unintended pregnancy, while having no effect on counterarguing. Also, the presence of humor reduced behavioral intentions to engage in unprotected sex. Implications of the findings for safe sex communication are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
