A Video-Based Behavioral Intervention Associated with Improved HPV Knowledge and Intention to Vaccinate.

The aim of this study was to design, develop, and evaluate the feasibility of a theory- and evidence-based intervention to improve human papillomavirus (HPV) and HPV vaccine knowledge and intention to vaccinate, among parent-daughter dyads. A theory- and evidence-based online behavioral intervention, "", was developed to improve HPV and HPV vaccine knowledge and intention to vaccinate. Knowledge, intention to vaccinate, and feasibility of the intervention were evaluated in a prospective, randomized, controlled feasibility trial. A total of 49 parent-daughter dyads completed the baseline knowledge assessment ( = 24 control, = 25 intervention), and 35 dyads completed the knowledge assessment at week 2 ( = 17 control, = 18 intervention). The intervention resulted in a statistically significant increase in HPV and HPV vaccine knowledge and intention to vaccinate. All intervention participants found the video interesting, while 96% found it useful. This intervention was found to be useful, effective, safe, and acceptable in this feasibility study.
