In contrast, the theory of planned behaviour distinguishes between behavioural intention and actual behaviour.
Nevertheless, many interventions were found to be successful in changing behaviour or behavioural intention.
Attitude direct, subjective norm, anticipated consequences, habitual behaviour and past behaviour significantly predicted behavioural intention.
This theory implies that the three predictors influence subsequent behaviour indirectly through behavioural intention.
This attitude toward the behaviour has an impact on behavioural intention, which in turn, affects behaviour.
It is purported that these beliefs predict behavioural intention to perform the behaviour, and performing the behaviour.
This research has highlighted the relative importance of the TPB constructs upon behavioural intention and subsequent behaviour.
Ajzen [ 3] suggests that a behavioural intention can find expression in behaviour only if the behaviour is under volitional control.
Based on the theory of planned behaviour, a model extending the predictors of behavioural intention was proposed in this study.
In other words, it is possible to use behavioural intention as a proxy for actual behaviour.
This is conceptually close to the behavioural intention construct in the theory of planned behaviour.
