Background: Effective interventions to promote human papillomavirus (HPV) vaccination are needed, particularly among populations at increased risk of HPV-related disease. We developed and pilot tested a web-based intervention, Outsmart HPV, to promote HPV vaccination among young gay and bisexual men (YGBM). Methods: In 2016, we recruited a national sample (n = 150) of YGBM ages 18–25 in the United States who had not received any doses of HPV vaccine. Participants were randomized to receive either standard HPV vaccination information (control) or population-targeted, individually-tailored content (Outsmart HPV intervention). We assessed between group differences in HPV vaccination attitudes and beliefs immediately following the intervention using multiple linear regression. Results: There were no differences in HPV vaccination attitudes, beliefs and intentions between groups at baseline. Compared to participants in the control group, intervention participants reported: greater perception that men who have sex with men are at higher risk for anal cancer relative to other men (b = 0.34); greater HPV vaccination self-efficacy (b = 0.15); and fewer perceived harms of HPV vaccine (b = −0.34) on posttest surveys (all p <.05). Overall, intervention participants reported high levels of acceptability and satisfaction with the Outsmart HPV intervention (all > 4.4 on a 5-point scale). Conclusions: Findings from this study provide preliminary support for a brief, tailored web-based intervention in improving HPV vaccination attitudes and beliefs among YGBM. An important next step is to determine the effects of Outsmart HPV on HPV vaccine uptake. Clinical trials registration: ClinicalTrials.gov identifier NCT02835755.
