Does Self-Efficacy Mediate the Relationships Between Social-Cognitive Factors and Intentions to Receive HPV Vaccination Among Young Women?

Drawing upon health behavior change theories, the current study examined whether self-efficacy mediated relationships between social-cognitive factors (i.e., perceived risk, perceived benefits, perceived barriers, perceived severity, and cue to action) and human papillomavirus (HPV) vaccination intentions among college women. Unvaccinated women (N = 115) aged 18 to 25 years attending a Midwestern university completed an anonymous web-based survey assessing study variables. Correlational analyses and mediation analyses were conducted. Self-efficacy mediated relationships between two social-cognitive factors (i.e., perceived barriers to HPV vaccination-indirect effect = -.16, SE = .06, 95% confidence interval [CI] = [-.31, -.06]-and perceived risk of HPV-related conditions-indirect effect = .16, SE = .09, 95% CI = [.01, .37]) and HPV vaccination intentions but was unrelated to the other three social-cognitive factors. Based on these findings, future research should test whether increasing self-efficacy through education on risk of HPV-related conditions and reducing barriers to HPV vaccination improves vaccine uptake in college women.
