How to Inform: Comparing Written and Video Education Interventions to Increase Human Papillomavirus Knowledge and Vaccination Intentions in Young Adults

Abstract

OBJECTIVE: To compare the efficacy of 2 human papillomavirus (HPV) educational interventions on increasing HPV knowledge and vaccination intentions in college students. PARTICIPANTS: Male (n = 60) and female (n = 140) undergraduates (M (age) = 20.4, SD = 2.3) recruited from a university in Montreal, Quebec, Canada, from October 2009 to March 2010. METHODS: Using theory-based interventions, participants were randomly assigned to either a written HPV pamphlet, an HPV video, or a control. HPV knowledge and vaccination intentions were assessed pre and postintervention. RESULTS: Low baseline knowledge and intentions were found across groups. Postintervention, participants in the written and video interventions had significantly higher knowledge and intentions than the control. No differences were found between written and video interventions on knowledge or intentions. CONCLUSION: This study, a first in comparing HPV educational formats, suggests that both written and video interventions are equally effective in educating about HPV and increasing young adults' vaccination intentions.
