Description
T RANSTHEORETICAL M ODEL (Prochaska et al., 1992) - Sometimes called stages of change ASSUMPTIONS OF TTM (Prochaska et al., 2008) 1. No single theory can account for all behaviour change 2. Behaviour change unfolds over time through stages 3. Stages are stable and open to change 4. No inherent motivation to progress through stages of change o There must be some intervention 5. Majority will not be served effectively by traditional action-oriented behaviour change programs o Example; smoking – if someone was told to go “cold turkey,” the program will not work. Immediate changes do not happen immediately, it must be done in stages 6. Specific processes & principles of change need to be applied at specific stages o Need something to keep moving you along 7. Stage-matched interventions have been designed mainly to enhance self-control 8. Behaviour change typically consists of several attempts where individual may progress, backslide, and cycle and recycle through changes a number of times o You will relapse, but we have something in place to minimize that BACKGROUND OF TTM - Stages of change - Why “transtheoretical” - Origins of smoking o Because of its success in smoking it was used in other areas; anorexia, obesity THE STAGES OFC HANGE 1. P RECONTEMPLATION : o No intention to take action in the near term, usually measured as within the next 6 months 2. C ONTEMPLATION : o Intends to take action within next 6 months 3. P REPARATION: o Intends to take action soon (usually within next 30 days) and has taken some steps in this direction  May have gone to see a physician, checked out a gym membership, found a friend (buddy system), etc. 4. A CTION: o Changed behaviour for less than 6 months o What counts? They aren’t merely being active, they are actually meeting the standards. They meet the criteria.  Ex: Yes I’m physically active and I’m getting 150 minutes of moderate activity a week 5. M AINTENANCE : o Changed behaviour for more than 6 months o Critical that relapse is minimized  “5 years,” it is a habit, it’s common 6. T ERMINATION : o No temptation to relapse, and 100% confident that you will do this behaviour PROCESSES OF C HANGE 1. C ONSCIOUSNESS RAISING: o Finding and learning new facts, ideas, and tips that support the healthy behaviour change  I.e. benefits of eating more dairy products, as well as negatives  New information can change behaviour 2. D RAMATIC R ELIE: o Increased emotions about unhealthy behaviours, followed by decreased affect if appropriate
