"Facts Tell… and With Stories Sell?" Combining Viewer-tailored Personal Human Papillomavirus (HPV) Narrative Video With HPV Vaccine Information Video to Improve HPV Vaccine Uptake
What this study is about
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 HPV vaccination.
View original scientific description
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 HPV vaccination.
Interventions
BEHAVIORAL
Informational Animation Video
The informational animation video will also take several minutes and will cover HPV disease, address specific concerns when identified, and the importance and safety of HPV vaccines.
BEHAVIORAL
Personal Narrative Video
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.
Primary outcome measures
Number of participants who receive HPV vaccination
Time frame: 9-month follow-up
HPV vaccination will be a binary variable (received vs not received)

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
