Background: Human papillomavirus is responsible for most sexually transmitted diseases globally.
Men who have sex with men have a higher incidence of human papillomavirus infection and related
health problems due to the nature of sexual risk activities. Vaccination is the most effective way to
prevent the transmission of virus strains, but the rate of human papillomavirus vaccination among
men who have sex with men remains low. Intention is the primary determinant of individuals’ behavior.
The extended Theory of Planned Behavior has been widely utilized as a theoretical framework to
examine vaccination intention and behavior in various populations and contexts worldwide.

Objective: This paper aims to examine the factors influencing human papillomavirus vaccination
intention of men who have sex with men.

Methods: This review was guided by Whittemore and Knafl’s five-step integrative review methodology,
which included problem identification, literature search, data evaluation, data analysis, and presentation. The
literature was searched from Cumulative Index to Nursing and Health Literature, Google Scholar, ProQuest,
PubMed, ScienceDirect, and Scopus databases. This review included articles based on the extended Theory of
Planned Behavior published in peer-reviewed journals and written in English or Thai between the years of 2000
and 2023.

Results: Factors influencing human papillomavirus vaccination intention of men who have sex
with men included attitudes towards getting a vaccination, subjective norms to get a vaccination,
perceived behavioral control to get a vaccination, sexual behaviors, and human papillomavirus
knowledge.

Conclusion: This review offers insights into the influential factors influencing human papillomavirus
vaccination intention of men who have sex with men that can be manipulated in nursing interventions
for improving human papillomavirus vaccination intention in this population.

Keywords: human papillomavirus, vaccination, intention, men who have sex with men, extended the-
ory of planned behavior
