Interventions

  • Informational Animation Video — BEHAVIORAL
    The informational animation video will also take several minutes and will cover human papillomavirus (HPV) disease, address specific concerns when identified, and the importance and safety of HPV vaccines.
  • Personal Narrative Video — BEHAVIORAL
    Personal narrative videos will consist of someone describing the person's own personal experience with HPV. The investigators have a collection of videos of personal narratives from different people that the investigators have cut to approximate several minutes in length so the investigators can tailor the personal narratives to match each study participant's race/ethnicity and gender as closely as possible.

Study Details

This study will compare the use of informational videos only, personal story videos only, and the combination of both, to see which is most effective in increasing vaccination among older adults.
