Study Summary
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.
Primary Outcome
Each parent will be asked to respond to this question. The response will be scaled from 1-10 in terms of parental intent regarding vaccination, with higher scores meaning greater parental intent to vaccinate children.
