Objective: In May 2021, U.S. states began implementing "vaccination lotteries" encouraging COVID-19 vaccination. Drawing from Prospect Theory and math cognition research, we tested several monetary lottery structures and their framing to determine which would best motivate unvaccinated adults. Method: In two online experiments, U.S.…

Objective: To examine correlates of and barriers to COVID-19 vaccine initiation and intention among college students. Participants: 1,171 students attending a public university in the South. Methods: Multivariate logistic regression was used to assess the correlates of vaccine intention and initiation. Reasons for pursuing or foregoing vaccination…

Misinformation has been a pressing issue since the beginning of the COVID-19 pandemic, threatening our ability to effectively act on the crisis. Nevertheless, little is known about the actual effects of fake news on behavioural intentions. Does exposure to or belief in misinformation about COVID-19 vaccines affect people's intentions to receive…

Objective: The Theory of Planned Behavior has been applied to COVID-19 protective behaviors, but evidence suggests this theory may be less predictive over time and less valid in individualistic societies. The current study applied this theory among American college students as vaccines became available and added perceived risk. Participants: 242…

On college campuses, effective management of vaccine-preventable transmissible pathogens requires understanding student vaccination intentions. This is necessary for developing and tailoring health messaging to maximize uptake of health information and vaccines. The current study explored students' beliefs and attitudes about vaccines in general,…

Objective: The study tested potential factors that differentiated the COVID-19 vaccine-hesitant and -inclined college students and, based on these factors, identified subgroups of the vaccine-hesitant students. Participants: Participants were 1,183 U.S. college students attending four-year universities or community colleges recruited through…

In January 2020, the World Health Organization declared the 2019 novel coronavirus (COVID-19) outbreak to be a public health emergency. More than 500 million cases and more than 6 million deaths have been reported, with these numbers growing each day. A major public health initiative for controlling the COVID-19 pandemic was vaccine development…

Objective: We investigated the preliminary efficacy of a tailored human papillomavirus (HPV) vaccination on-line intervention designed to increase HPV vaccination intention. Participants: Female college students (N = 101; 18-26 years), who have not received the HPV vaccine. Methods: Participants were randomized to either a control group to read…

Objective: This systematic mixed studies review aims to summarize the results of available research on knowledge of the human papillomavirus (HPV) and HPV vaccine, the intention to vaccinate, and HPV vaccination uptake among male college students. Methods: PubMed, ProQuest, EBSCO, PsycINFO, JSTOR, MEDLINE, and Google Scholar searches were…

Objective: Objective: Sexual promiscuity stigma constitutes a significant barrier which prevents young women from receiving catch-up human papillomavirus (HPV) vaccinations. Our objective was to explore how this stigma may be particularly detrimental to women in cultures of honor, where women are expected to maintain a reputation of sexual purity.…

The gap in knowledge and information-seeking between high and low socioeconomic status (SES) has been well documented. This study extends this knowledge gap hypothesis to narrative persuasion in the context of parents' knowledge and information-seeking intention concerning adolescents' COVID-19 vaccination. It specifically tests if the gap is…

To examine mental health status, COVID-19 vaccine intention and barriers among college students in the U.S. Participants: Students (n = 337) registered at a large public university in 2021. Methods: Cross-sectional survey data were collected online and analyzed using independent samples t test, chi-square test, and one-way ANOVA. Results: Compared…

Background: Pregnant women are at increased risk of complications from flu, but uptake of flu vaccination is below 75% targets. Evidence suggests that changing illness risk appraisals may increase vaccination behaviour. In 2018-2019, researchers, public health specialists, and pregnant women co-designed a short animation targeting (unhelpful)…

Background: Vaccine misinformation has been widely spread on social media, but attempts to combat it have not taken advantage of the attributes of social media platforms for health education. Methods: The objective was to test the efficacy of moderated social media discussions about COVID-19 vaccines in private Facebook groups. Unvaccinated U.S.…

Objective: The purpose of this study was to compare the effect of text and video formats of an online theory-based Meningitis B (MenB) health message intervention on college students. Participants: College freshmen and transfer students admitted at a Southern U.S. University. Methods: In a 2-arm randomized study, knowledge, perceptions, and…
