The Theory of Planned Behaviour (TPB) suggests that behaviour is influenced by intention. Intention, in turn, is influenced by attitude, subjective norms, and perceived behavioural control (PBC). The researcher examined the role of the TPB constructs in affecting intention and gambling behaviour. They also wanted to know if past gambling behaviour and habit affected gambling behaviour. They recruited 250 university students and asked them to fill out questionnaires that assessed these variables. Of those students, 180 filled out another questionnaire about their gambling behaviour four weeks later. The researcher found that attitude, PBC, past behaviour, and habit were significant predictors of intention and of gambling behaviour. Importantly, past behaviour influenced gambling behaviour through PBC and habit. These results suggested that past gambling behaviour could lead to the development of gambling habit and decrease the perception of control over gambling. This could lead to future gambling behaviour.
