Transtheoretical Stages of Change

If a client answers either question between 1-4, assume they are in pre-contemplation and consider the following steps:

•Acknowledge the client’s control of decision•Give your opinion on the medical benefits of weight loss.•Explore concerns from the client’s view•Acknowledge possible feelings of being pressured to change•Validate that they are not ready and that it is solely their decision•State that, at this time they are not ready, but that it is possible they may feel differently at a future time.

Answers between 5-7 indicate some continued ambivalence, assume clients are in contemplation.•Validate client’s experience•Restate that the decision to change is still completely their own•Clarify pros and cons of changing behavior•Leave opportunity for continued movement toward change

If answers are between 8-10, assume they are ready to take action and help prepare them for behavior change.•Praise decision to change behavior•Identify and assist in problem solving regarding obstacles•Encourage small initial steps•Help identify social supports•Provide future follow-up appointments to assist with adherence

• Based on dysfunctional cognitions and beliefs• Modify behaviors by changing

antecedents and

consequences
