Purpose: This study aimed to identify the actor and partner effects of human papillomavirus (HPV) vaccination knowledge, health beliefs, and self-efficacy on parental intentions to vaccinate adolescent sons against HPV. Methods: The participants were 191 couples who met the eligibility criteria. Data were collected from June 2024 through internet communities in Gyeongsangnam Province. The actor-partner interdependence model was used to analyze the parent's actor and partner effects of HPV vaccination knowledge, health beliefs, and self-efficacy on parents' intentions to vaccinate their adolescent sons against HPV. Results: The actor effects of fathers' intentions to vaccinate their adolescent sons against HPV were perceived benefits and self-efficacy; however, the partner effect was not significant. The actor effects of mothers' intentions to vaccinate their adolescent sons against HPV were perceived susceptibility, perceived severity, perceived benefits, and self-efficacy, and the partner effects were fathers' perceived severity and benefits. Conclusion This study indicates that fathers' intentions to vaccinate their adolescent sons against HPV may play an essential role in increasing HPV vaccination rates among adolescent sons.
