Dr. Reiter's research addresses cancer prevention and control through two main thematic areas, cancer screening and vaccination. Both health behaviors are effective strategies for reducing disease burden, yet remain underutilized. He is particularly interested in examining the determinants of engaging in these behaviors and then applying that information to develop and test behavioral interventions that can reduce health disparities.

For the current study, Dr. Reiter and his collaborators will test a theoretically informed mobile health HPV vaccine intervention for young sexual minority men. Sexual minority men have high rates of HPV infection and HPV-related disease, yet many remain unvaccinated against HPV. To address this issue, Dr. Reiter and his collaborators recently developed and pilot tested an HPV vaccine intervention for young sexual minority men. The current study will extend this line of research by comprehensively evaluating the intervention and providing an evidence base on its efficacy, mediators, and moderators. Findings will provide a sophisticated understanding of the intervention that is needed to effectively and efficiently disseminate it in the future.
