Attempt to improve our ability to predict and affect behaviour by addressing the gap between intention and behaviour.
Provide a step-by-step explanation for how someone develops intention and then carries the intention through to behaviour, both short and long-term.
Assessment of the costs associated with a course of action compared to the benefit of the individual’s health
Perception that a threat-reducing strategy will work
Gollwitzer. Posits that people who have an implementation plan are much more likely to engage in that behaviour.
Bagozzi. Similar to Gollwitzer's, but also considers a person's thoughts about the nature of the goal and the expression of intentions about the goal.
A hybrid theory of Reasoned Action with the addition of perceived behavioural control. Behaviour is preceded by intention and that intention is influenced not only by subjective norms and beliefs about efficacy of the behaviour, but also by the belief that one is actually capable of performing the behaviour.
Belief that a specific behaviour is within one’s control
Behaviour is preceded by intentioned and that our intention is influenced by beliefs about the behaviour and subjective norms
