From: Towards improved uptake of malaria chemoprophylaxis among West African travellers: identification of behavioural determinants

Figure 1

Behavioural model for obtaining pre-travel advice, buying anti-malarial tablets and starting anti-malarial tablets. Experience includes experience of disease, of the use of chemoprophylaxis and previous travel. Personality variables include demographics and travel details. Social includes social support and model behaviour. Determinants were structured based on three behavioural models. The Theory of Planned Behaviour (TPB) includes external variables (demographics, personality traits and environmental influences), attitudes (whether people regard a given behaviour positively or negatively), subjective norms (what the social environment thinks about the behaviour and how it acts) and perceived behaviour control (PBC) (expected personal performance of behaviour) as determinants. These determinants influence intention to perform behaviour, and intention predicts whether behaviour is performed. In the Health Belief Model (HBM), motivation to perform behaviour, perceived health threat and perceived reduction of this threat determine whether a given behaviour is performed. The Protection Motivation Theory (PMT) includes perceived severity of a threatening event, vulnerability of individuals (the chance that the health threat will occur), efficacy of recommended preventive behaviour and self-efficacy (defined as PBC in the TPB). This theory includes previous behaviour as an additional determinant.
