West 2005

Question 3

What did West 2005 say about TTM?

Answer 3

West states that

• The model is flawed with the most basic tenet the stages of change
• Boundaries of stages are merely lines in the sand
• Classifying individuals in stages assumes everyone has stable plans - people might just stop
• Decision making and process planning draws attention away from reward and punishment
• To much power - people who want to change are more likely to do it
• No evidence shows that moving someone closer to action results in a sustained change in behaviour at a later date

Question 4

Example backing up West 2005 critique..

‘the measurements between the stages are merely arbitrary lines in the sand’

Answer 4

someone who plans to quit smoking in 30 days will be in the prep stage

Question 5

DiClementes Response to West 2005..

Answer 5

Wests critique focuses more on the stages of change rather than the entire model

TTM offer a framework that makes element to human intentional behaviour process not just stages

Stages are considered states not traits

Readiness to change is not a single construct, but a compilation of tasks and accomplishments that can produce momentary and sustained change.
