Study Title

Health Beliefs, Behaviors, and Healthcare Experiences among a National Sample of United States Young and Mid-Age Adults


The study will provide important insight into current HPV vaccine knowledge/awareness, health beliefs, affect, vaccine discussions, decision preparedness, and vaccine intentions and behaviors among those ages 18-45, while examining potential differences in responses between those ages 18-26 and those ages 27-45 and vaccinated and unvaccinated individuals. In addition, the study will illuminate gaps in knowledge and awareness as well as the education intervention preferences (e.g., intervention platform, source of information, timing of intervention) of individuals ages 18-45. Among those ages 27-45, shared clinical decision-making is recommended. Compared to individuals ages 18-26, individuals ages 27-45 may need to be supported uniquely so that they are prepared to engage in shared clinical decision-making about HPV vaccination with their healthcare provider. Thus, among unvaccinated individuals ages 27-45, for whom shared clinical decision-making is recommended, preparedness for engagement in shared clinical decision-making will be assessed and explored. The study also will allow investigators to identify how best to target information to young adults and mid-adults both for themselves, and among those with children, for their children.


Aim 1: To describe HPV/HPV vaccine knowledge, health beliefs, health behaviors, attitudes, health-related emotions, information sources, health literacy, health care experiences, discussions about HPV and the HPV vaccine, and HPV vaccine uptake and intentions and examine relationships between these variables among a national sample of U.S. adults (N=4,000) ages 18-45 years. Aim 2: Among the subset of participants ages 18-45 with at least one child, to examine the associations between sociodemographics, knowledge, health beliefs, individuals own HPV vaccination status and intentions, and intentions and behaviors to vaccinate at least one child who is age 9 and older. Aim 3: To characterize HPV-related educational intervention preferences among a national sample of U.S. adults ages 18-45. Aim 4: To examine the impact of the COVID-19 pandemic on receipt of healthcare and HPV vaccination receipt intentions among a national sample of U.S. adults ages 18-45.
