A Tailored, Health Communication Intervention for HPV Vaccine Hesitant Families

HPV-Related Carcinoma, Human Papilloma Virus, Parents, Program, Communication, Vaccine Refusal

The human papillomavirus (HPV) causes 90% of cervical cancers and is implicated in multiple other cancers. The HPV vaccine can prevent the vast majority of these cancers, but it is underused in adolescents, especially among those within vaccine hesitant (VH) parents. The proposed research is to develop and pilot test a tailored, health communication intervention aimed to increase HPV vaccination among VH parents. The proposed research is innovative because no evidence-based health communication interventions target HPV VH parents, and we will use stakeholder engagement throughout this study. The research will add knowledge on how tailored education provided before a doctor's visit can play a role in improving HPV vaccination rates among underserved, VH parents.

The goal of this K01 application is to develop and pilot test an individually tailored, pre-visit health communication intervention targeting HPV-VH parents. The partnering clinic is Meharry Medical College Pediatric Group (MMC Pediatrics), a safety-net clinic serving primarily publicly-insured and uninsured patients. The study has three specific aims. Aim 1. To develop a tailored, health communication intervention targeting HPV-VH parents prior to clinic visits. The tailored intervention will be delivered to VH parents via mobile phones. Investigators will draft initial content based on the Theory of Reasoned Action and Health Belief Model, previous VH research,14 and preliminary data. Then semi-structured interviews will be conducted with 25-30 VH parents who previously declined the HPV vaccine and 10 physicians to elicit feedback on draft content. Qualitative data will be collected and analyzed iteratively, informing successive modifications to the intervention to cover a range of potential concerns for VH parents, enhance message relevance, and refine the intervention delivery process. Next, investigators will work with MMC Pediatrics to develop and refine the study protocol. Investigators will pre-test and get feedback on the protocol from 16 VH parents and 3 physicians to maximize acceptance and feasibility. Aim 2. Conduct a pilot study of the intervention and study protocol to demonstrate feasibility for the future full-scale randomized control trial (RCT). Based on Aim 1, investigators will conduct a small, pilot RCT with 70 VH parents with scheduled clinic visits. Feasibility indicators are recruitment rates, retention rates, and ability to ascertain patients' post-visit HPV vaccine status in the clinical record. VHealth software will be used to extract information from the EHR to identify potentially eligible patients with a previous HPV vaccine refusal and to determine the whether an HPV vaccine dose was received during the scheduled visit. Aim 3. Examine acceptability of the intervention and protocol among parents and providers. Parents participating in the pilot study will complete a post-visit survey to measure acceptability of the intervention and protocol, provider trust/rapport, and satisfaction with provider-patient communication. In addition, investigators will conduct semi-structured debriefing interviews with a subset of 20-30 parents and 3 providers to gather qualitative data about their experiences (e.g., unforeseen problems and barriers) and their perceptions of acceptability of the intervention and protocol (e.g., ease of use, content, graphics). The findings will be used identify needs for any additional modifications to the intervention and protocol prior to the RCT.
