The Theory of Planned Behaviour. (Azjen I, (2002)

The Theory of Planned Behaviour suggests that behaviour is driven by behavioural intentions. These are a function of: Attitude Towards the Behaviour — beliefs about the consequences of the behaviour and an appraisal of the positive and negative aspects of making a change. Subjective Norms - (do people important to the individual think that the behaviour should be performed). What ‘significant others’ do and expect and the degree the person wants to conform and be like others. Perceived Behavioural Control - (perception of how easy or difficult it would be to perform the behaviour). This is often described as self-efficacy.
