- Attitude - you beileve giving up smoking will improve your health, save money, that it will be differcult and you may suffer withdrawal symtoms.
- Subjective norms - most of your friends have given up and would be supportive of you. Your flatmate still smoker and ridcules people who are trying to quit and parents still smoke.
- Perceived behavioural control - very important component. Explains intention- behaviour gap linked to self efficacy. Behavioural intention - attitudes you have toward giving up. combined with subjective norms and preceived control will inflence and predict behaviour.
- Rise et al found that an affective attitude and descriptive norm were the most powerful predictors of behaviour.
- Model are criticiized for being to rational and ingorning the role of emotion, irrational throughs etc.
- intention/behaviour gap - predicts intention rather the actual behaviour change. Qusetionaire used to measure aspects of the model measure the intention rather than the behaviour,leading to a compromise of vailidity.
- This model focuses on where the main problems lie, which need taking care of first. It can be the patients attitude toward quit or family and friend or precived behavioual control.
