"Protect their Future": Evaluating the Effectiveness of a Brief Video Intervention to Improve Adolescent Immunization

Mon, May 25, 12:00 to 13:15, Caribe Hilton, Auditorium

Abstract

Rates of HPV and influenza vaccination remain low in poor, medically underserved Appalachian communities. This study will present the results of the first video efficacy study of the Rural Cancer Prevention Center's "Protect Their Future” intervention. The intervention was designed to improve adherence to age-appropriate adolescent vaccination outcomes in a medically underserved community. The intervention was delivered by video by iPads to parents of adolescents.

99 parents in the intervention completed pre- and post-test surveys via custom-developed audio-assisted iPad interview software. Evaluation of the video’s strong perceived message effectiveness was evaluated with high reliability (alpha = .93). After watching the video, parents who had at least one adolescent child who had not been vaccinated with HPV, were 6.25 times more likely to intend to have their adolescent male child receive HPV vaccination, compared to parents who did not (p <.001). Similarly, parents who had at least one adolescent child who had not been vaccinated against HPV, were 1.38 times more likely to intend to have their adolescent female child receive HPV vaccination (p <.001). Parents’ beliefs in the vaccine’s efficacy also improved after viewing the video (t = 1.88, p = .06). Parents of adolescents were also significantly more likely to intend to have their adolescents immunized for influenza (t = 2.516, p = .014) after watching the video. The “Protect their Future” video intervention demonstrates an approach to improving adolescent immunization education that can be appropriately scaled and culturally-tailored to improve intention to complete all age appropriate vaccinations in other populations.
