Treatments tested in this trial

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.
