In Hong Kong, human papillomavirus (HPV) vaccination, which can prevent genital warts and some cancers, is very low among males, and previous studies have reported zero uptake among a group vulnerable to HPV infection: men who have sex with men (MSM). This randomised controlled trial (RCT) evaluated the relative efficacies of 2 web- and theory-based interventions with and without brief motivational interviewing (MI) over the phone. MI is a client-centred, nondirective, goal-oriented counseling technique that can help clients explore and resolve any ambivalence that might have to change. The goal was to determine how best to increase the completion of HPV vaccination within a 24-month follow-up period among unvaccinated Hong Kong Chinese MSM compared with a control group.
