A video-based behavioural intervention associated with improved HPV knowledge and intention to vaccinate

Abstract

AimsThe aim of this study was to design, develop and evaluate a theory and evidence-based intervention to improve human papillomavirus (HPV) and HPV vaccine knowledge, and intention to vaccinate, among parent-daughter dyads. MethodsA theory and evidence-based online behavioural intervention, "Is the HPV vaccine for me?" was developed to improve HPV and HPV vaccine knowledge, and intention to vaccinate. The impact and feasibility of the intervention was evaluated in a prospective randomised controlled feasibility trial. ResultsA total of 49 parent-daughter dyads completed baseline knowledge assessment (n=24 control, n=25 intervention), and 35 dyads completed knowledge assessment at week 2 (n=17 control, n=18 intervention). The intervention was associated with 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. ConclusionsThis intervention was found to be affordable, practicable, effective (cost-effective), acceptable, safe, and equitable, in this feasibility study.
