  1. An Overview of Prochaska and DiClemente’sStages of Change Model Developed by Catherine Segan for the Victorian Smoking and Health Program September, 1999 The Victorian Smoking and Health Program is a joint initiative of the Anti-Cancer Council of Victoria, the Department of Human Services, the National Heart Foundation and the Victorian Health Promotion Foundation.  The Quit logo is a registered trademark of the Anti-Cancer Council of Victoria.

  2. Key Features of the Stages of Change Model • Deals with intentional behaviour change • Views change as a process rather than an event • The change process is characterised by a series of stages of change • In attempting to change a behaviour a person typically cycles through these stages of change

  3. What are the Stages of Change? The stages describe a person’s motivational readiness or progress towards modifying the problem behaviour Precontemplation: not considering quitting in the next 6 months Contemplation: seriously considering quitting in the next 6 months

  4. What are the Stages of Change? (Cont’d) Preparation: planning to quit in the next 30 days Action: the first 6 months of staying quit Maintenance: quit for more than 6 months Relapse: transition to an earlier stage

  5. Termination Maintenance Relapse Action Contemplation Preparation Precontemplation Figure 1: Prochaska and DiClemente’s Wheel of Change

  7. What helps people move forward through the Stages of Change? • Processes of Change • Decisional balance • Self-efficacy

  8. 10 Processes of Change • Coping activities or strategies used by people in their attempts to change • Each change process is a broad category of coping activities which encompasses multiple techniques, methods and interventions

  9. Two Main Types of Change Processes Cognitive change processesInvolve changes in the way people think and feel about their smoking Behavioural change processesInvolve people making changes to their smoking behaviour

  10. 5 Cognitive Processes Consciousness raisingIncreasing information about yourself and smoking e.g. - thinking about health effects of smoking - a doctor asking whether you smoke - thinking about how you’re running out of breath - reading the Quit book - watching the Quit TV ads

  11. 5 Cognitive Processes Dramatic reliefExperiencing strong emotional reactions to events associated with smoking e.g. - deciding to do something about your smoking after your grand mother is diagnosed with lung cancer - seeing the effect of blowing smoke through a white handkerchief

  12. 5 Cognitive Processes (Cont’d) Environmental reevaluationBecoming aware of the impact of the problem behaviour on others e.g. - thinking about the effects of smoking around the kids - noticing cigarette butts on the street

  13. 5 Cognitive Processes (Cont’d) Self-reevaluationAffective and cognitive reexperiencing of one’s self and problems e.g. - thinking that you’re no longer happy being a smoker - imagining yourself as a non-smoker

  14. 5 Cognitive Processes (Cont’d) Social liberationNoticing and using social conditions that support personal changes e.g. - noticing the non-smoking areas around you - joining a quit smoking course

  15. 5 Behavioural Processes Self-liberationBelief in your ability to change and commitment to act on that belief e.g. - telling yourself that you can quit smoking - setting a quit day - telling others you’re quitting

  16. 5 Behavioural Processes (Cont’d) Helping relationshipsTrusting others and accepting their support in quitting e.g. - asking a friend who used to smoke for help - calling the Quitline

  17. 5 Behavioural Processes (Cont’d) Counter conditioningReplacing smoking with more positive behaviours and experiences e.g. - “Do something else”

  18. 5 Behavioural Processes (Cont’d) Reinforcement managementRewards for staying quit e.g. - the family showering you with praise- buying yourself a magazine, CD, flowers - telling yourself how wonderful you are

  19. 5 Behavioural Processes (Cont’d) Stimulus controlAvoiding or countering stimuli that elicit the problem behaviour e.g. - cleaning up ashtrays before your quit day - not going to the pub the day after you quit - putting up no smoking signs

  20. Relationship between Processes and Stages of Change Cognitive change processes help people to move through the early stages of change i.e. from not thinking about quitting to deciding to quit Behavioural change processes help people to move through the later stages of change i.e. from making a quit attempt to staying quit

  21. Decisional Balance • Decisional balance is the importance a person gives to the perceived advantages (pros) and disadvantages (cons) of smoking, and of quitting • An individual’s motivation to change is affected by his/her decisional balance

  22. Decisional Balance (Cont’d) • Decisional balance changes across the stages of change • Use of cognitive change processes can help tip the decisional balance in favour of quitting

  23. Figure 3. Decisional Balance Across the Stages of Change From Prochaska, Velicer, Rossi et al. 1994 pg.43

  24. Self-efficacy • Self-efficacy is a person’s confidence in his/her ability to quit, and to resist temptations • Confidence to resist temptations to smoke varies across the stages of change, being lowest in Precontemplation and highest in Maintenance • Self-efficacy is a strong predictor of success in the Action and Maintenance stages

  25. How is the Model Useful? • Provides a framework for understanding the process of how people change • Recognises that people in different stages of change need different types of interventions to help them progress. • Quit Victoria has developed goals and strategies for counselling clients at each of the stages of change
