The research aimed to explore beliefs about influenza and influenza vaccination, and the social influences on decisions whether or not to accept the influenza vaccination in a sample of urban-dwelling Thai adults. It also aimed to test the effect of a Health Action Process Approach (HAPA)-based leaflet on influenza vaccination behaviours among these high-risk individuals, and to evaluate the impact of a HAPA-based leaflet on potential mediators of behavioural change. Additional aim was to examine the predictive utility of the HAPA model in relation to both intention and subsequent vaccination behaviour in a certain high risk group. Firstly, a qualitative study was carried out. In-depth interviews were conducted among 20 high-risk individuals who were either (i) aged 65 and over, or (ii) under 65 years with chronic diseases that had clinical indications requiring influenza vaccination. Findings indicate that most participants had insufficient knowledge about influenza and influenza vaccination. Their decisions whether or not to get vaccinated against influenza were based on a number of factors, including salience of risk, influence of others, perception of the need for preventive health care, and the availability of influenza vaccine. Secondly, a controlled before and after trial was conducted. Participants in the intervention (n = 99) received a HAPA-based leaflet and asking them to form an action plan identifying where, when and how they would seek vaccination. Those in the comparison condition (n = 102) received a standard government information leaflet. The HAPA intervention resulted in greater changes on measures of risk perception, outcome expectancies, self-efficacy, and intention than the comparison condition. No significant difference in vaccination rates was observed between two groups. Influenza vaccination was directly predicted by self-efficacy and intention.
