Applying the theory of planned behavior to predict COVID-19 booster vaccination intentions of college students.

Objective: The purpose of this study was: (a) to determine COVID-19 vaccination rates among college students, (b) to assess what proportion of college students self-report currently or previously having COVID-19, and (c) to test theory of planned behavior (TPB)-based constructs in predicting the COVID-19 booster vaccination behavioral intentions. Methods: A non-experimental, cross-sectional study design was applied. Participants: The sample consisted of 288 college students ages 18 years and older. Results: The stepwise multiple regression revealed that attitude (β = .329; p < .001) and subjective norm (β = .244; p < .001) were statistically significant predictors of intention to receive the COVID-19 booster, accounting for 86.7% (Adjusted R² = .867, F (2, 204 = 673.002, p < .001) of the variance. Conclusions: College students are at high risk for more severe complications of COVID-19 infection due to low vaccination rates. The instrument designed for this study may be used to design TPB-based interventions to increase COVID-19 vaccination and booster intentions of college students.
