Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate mother's attitudes about vaccinating their 11-14 year old children against the human papillomavirus (HPV). Among mothers who do not plan to vaccinate their child, the investigators will assess the influence of brief videos tailored to mothers' questions and concerns. Mothers will be randomized to one of three arms: 1. General video message about vaccination; 2. General message plus a brief video addressing the mother's primary concern; or 3. General message plus videos address all of mother-indicated concerns. The outcome of interest is intention to vaccinate. Our hypothesis is that the tailored videos will lead to increased intention to vaccinate.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Attitudes will be assessed through a Web-based survey administered by Survey Sampling International (SSI). The projected sample size is approximately 3,500, comprising mothers or female guardians of at least one child aged 11-14 who live in the United States. The survey will take no more than 20 minutes to complete. Mothers who indicate that they do not plan to vaccinate their children in the next year will be randomized to view brief videos tailored to their questions or concerns about HPV vaccination. The outcome of interest is intention to vaccinate. Mothers who have vaccinated their child or intend to vaccinate their child will be asked a separate set of questions relevant to this information.

Mothers who indicate that they do not intend to vaccinate their child against HPV will be asked about their questions or concerns regarding HPV vaccination (from a pre-populated list of common concerns). Mothers will be randomized to one of three arms: 1. A general information video; 2. The general video plus a video addressing their top concern; or 3. The general video plus one or more videos addressing all of their concerns. Each video is less than 50 seconds in length.

Participants Investigators
Intervention videos delivered via anonymous online surveys through Survey Sampling International. Randomization to condition is built into the online survey. Participants will not know to which condition they will be randomized. Investigators are blinded by virtue of the built in randomization and anonymity of the survey.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

General Vaccine Information

Brief (47 second) animated informational video about vaccines recommended for all young adolescents.

Group Type NO_INTERVENTION

No interventions assigned to this group

Top Concern Tailored Intervention

Intervention includes the General Vaccine Information video plus a brief (\< 50 sec) animated video address the parent's top ranked question or concern from the provided list of possible concerns: 1. "I need more information about the vaccine"; 2. "My child is too young"; 3. "I am concerned about the long-term health effects or safety of the vaccine"; 4. "My child's health care provider did not recommend it or said my child could wait"; 5. "The vaccine is not required for school"; 6. "Other / none of the above". For those indicating #6, they will receive the same video as those indicating #1 (need more information).
