Hashtag HPV: HPV Vaccine Twitter Education Program

Parents use social media as an important parenting tool and source for health information. Using social media data to examine public opinion has had an early impact in public health and in cancer control and prevention efforts, including about the human papillomavirus (HPV) vaccine. A next step in this area of research is to develop and share messages on social media with parents to help inform and educate them about the HPV vaccine - ultimately assisting them with their decision to vaccinate their child. This study will evaluate the efficacy of social media messages through Twitter, using a randomized controlled trial to determine what types of messages resonate with parents. The investigators will examine differences between two types of messages - narrative messages (i.e., stories) and non-narrative messages (i.e., numbers and facts).
