Designing a Web App to Promote Teen Vaccination Uptake

Designing a Web App to Promote Teen Vaccination Uptake

Ms. Julia Berteletti, KB Research Program Manager, is presenting a poster on formative research from the BeVaccinated Project at the 39th Annual Meeting and Scientific Sessions of the Society of Behavioral Medicine, April 11-14, 2018 in New Orleans, Louisiana.

While vaccination rates for young children in the United States currently meet recommended standards, the Centers for Disease Control and Prevention reports adolescent vaccines uptake to be less than optimal, and in the case of the Human Papillomavirus (HPV) vaccine, seriously below desired uptake levels. To address this deficit, a web-browser application prototype, BeVaccinated, was developed to test reactions to and feasibility of delivering adolescent vaccine information via smartphone. The BeVaccinated app prototype was developed from formative research with 26 focus group participants and guided by an Expert Advisory Board comprised of vaccination experts and clinicians.

Usability testing on one module, about deciding to vaccinate, was conducted iteratively with nine parent and teen pairs in New Mexico and seven parent and teen pairs in Colorado. Pairs were comprised of one teen (ages 13-17) and their accompanying parent or guardian. Usability testing was conducted individually with the parent and teen by trained research staff. During the testing, participants used the app prototype, answering questions as prompted. At the conclusion of testing, participants completed the 10-item Bangor System Usability Scale (SUS). Parents and teens rated the app as very easy to use. SUS data also indicated that participants could quickly learn to use the app and that they would be confident using it.

A Specifications Document outlines the planned design of the full-scale app based on testing results. Findings included in the specifications document are: 1) provide tailored learning experiences to teens (i.e., game-based) and parents (i.e., didactic) within the same app; 2) integrate individualized information (e.g., clinic preferences); and 3) provide a vaccination record tracking feature. The planned app could improve dissemination of vaccine information, enhance parent/teen communication around health behavior choices, and ultimately, improve the uptake of vaccinations.

This research was funded by a grant from the Eunice Kennedy Shriver National Institute of Child Health and Human Development (R41HD082901; Dr. Gill Woodall, KB Senior Scientist, PI) Research collaborators included Dr. Randall Starling and Dr. Lance Chilton from the University of New Mexico, Dr. Gregory Zimet from Indiana University, Dr. Nathan Stupiansky from the University of Arizona, and Sophia Strickfaden from KB.
