Social-contextual factors interact with masculinity to influence college men's HPV vaccination intentions: The role of descriptive norms, prototypes, and physician gender.

Men's low HPV vaccination uptake and HPV-related disease incidence are public health issues; gendered social-contextual factors likely play a role. In Study 1, college men (N = 130; M age  = 19.55; white = 58.1%) reported their social cognitions (male-referent descriptive norms and prototypes), self-reliance masculinity ideology, and vaccination intentions. In Study 2, college men (N = 106; M age  = 19.32; white = 61.3%) were randomly assigned to receive HPV vaccination information from a man or woman physician-avatar. Descriptive norms and favorable prototypes (bs ≥ .337; ps ≤ .016) were associated with higher HPV vaccination intentions. Men with higher self-reliance masculinity had higher HPV vaccination intentions with a man physician and when they perceived greater vaccination among men (ps ≤ .035). Men with higher self-reliance masculinity are more sensitive to gendered social-contextual effects in HPV vaccination decision-making. Gendered social-contextual factors should be integrated into public health interventions to increase college men's HPV vaccination uptake.
