Abstract

Latinx populations have unique barriers to HPV vaccination. In the current study, we assessed the effectiveness of an online intervention to increase HPV vaccination intentions among patients of clinics that principally serve a Latinx population (n = 85%) as part of a randomized control trial (RCT). Participants viewed on an iPad either an individually tailored educational website (CHiCOS) or untailored information derived from the Vaccine Information Sheet (VIS) for HPV. Vaccination intention and related covariates were assessed via survey items administered before (pre-test) and after (post-test) viewing the material. No statistically significant differences were seen in changes of intention to vaccinate between groups (N = 1294). However, 16% of all (tailored and untailored combined) participants increased in their intention to vaccinate, while 7% decreased in intention. Overall 72% of participants had high intentions to vaccinate, yet far fewer actually received a vaccine dose. The current study explores implications of the demonstrated intention-behavior gap. As such, it presents opportunities to improve future interventions—specifically those that employ tailored messaging.
