PURPOSE: This descriptive study identified factors influencing high school students' intentions to receive human papillomavirus (HPV) vaccination using Ajzen's theory of planned behavior as the guiding framework. METHODS: Participants were 192 male and female high school seniors aged 18 years or older who could express their opinions independently. In April 2023, participants completed structured, self-administered questionnaires assessing HPV vaccination intention, HPV knowledge, attitudes toward HPV vaccination, subjective norms, and perceived behavioral control. Data were analyzed using independent t-tests, one-way analysis of variance with the Scheffé post hoc test, Pearson correlation coefficients, and hierarchical multiple regression. RESULTS: Intention to receive HPV vaccination was significantly predicted by subjective norms (β=.31, p<.001), perceived behavioral control (β=.31, p<.001), attitudes (β=.22, p<.001), and school gender composition (β=.19, p=.005). Subjective norms and perceived behavioral control exerted the greatest influence and together explained 54% of the variance in intention (adjusted R2=.54). CONCLUSION: These findings provide fundamental evidence for developing effective interventions to enhance high school students' intentions to receive HPV vaccination. Efforts should focus on fostering positive perceptions of HPV vaccination by providing accurate information about its benefits and potential adverse effects, supported by credible public messaging.
