Applying the health belief model to understand college students' intention to vaccinate against the seasonal influenza: Opportunities for health promotion
Method: College students from across the U.S. were recruited through MTurk, an online system where surveys can be completed for payment. Participants completed a survey assessing perceived severity and susceptibility for the flu, perceived barriers and benefits of the flu vaccine, cues to action, and intention.
Results: Exploratory and confirmatory factor analyses, consistent with classical test theory, supported the new measures with good to excellent reliability (α=0.64–0.92) and adequate fit. Two subscales were identified for perceived barriers (potential risks and process barriers), cues to action (influential others and popular media), perceived severity (severity of the flu and complications of the flu), and perceived susceptibility (susceptibility to the flu and perceived exposure risk). The multiple linear regression analysis predicted 60.6% of the variance in intention to vaccinate, F(9, 751)=128.23, p<0.001, R2=0.606. The three strongest predictors included: cues to action - influential others (t(751)=8.96, p<0.001), severity of the flu (t(751)=8.31, p<0.001) and susceptibility to the flu (t(751)=7.34, p<0.001).
Conclusion: Engaging influential others (doctors, nurses) in providing college students cues to get vaccinated, and increasing knowledge and awareness of perceived severity and susceptibility, should be addressed in an effort to increase vaccination rates on college campuses.

Qualified on the content I am responsible for because: I was responsible for the design and analysis of the study being presented. I have substantial experience with scale development approaches with three peer-reviewed manuscripts detailing the development of measures for use with blood donors. Understanding college students' vaccination intention and behavior to identify opportunities for intervention is a current area of research interest for me.
