Some of the studies conducted to explain COVID-19 vaccination intention have drawn on behavioural theories, such as the Theory of Planned Behavior (TPB) and the Health Belief Model (HBM). In light of the notion that COVID-19 vaccination is an innovative behaviour, the present study draws on Diffusion of Innovations (DOI) Theory to explain how this behaviour will be adopted in the early phase and gradually become diffused as a common practice. The DOI proposes 4 factors that would explain the uptake of innovative behaviour: (i) attributes of the innovation (perceived efficacy of the COVID-19 vaccine); (ii) communication channel (social media use for COVID-19-vaccine-related information); (iii) characteristics of the adopters (open

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.
