Which stage of the Transtheoretical Model is associated with actively changing behavior to sustain change?

• A. Precontemplation
• B. Contemplation
• C. Preparation
• D. Action

Answer: (D)

In this model, the stage where you are actively making and implementing changes to your behavior is the Action stage. That’s when you’ve moved beyond simply thinking about or planning change and you’re actually doing new behaviors and using strategies to make the change happen. It’s the period of tangible change—you’re cutting back or stopping the old behavior, adopting new routines, finding ways to cope, and applying the plan you’ve prepared. The goal during this stage is to solidify these new behaviors and keep them going as you continue toward longer-term change.

Maintenance, by contrast, comes after the initial change has been made, focusing on sustaining the new behavior over time and preventing relapse. Precontemplation and contemplation are earlier stages where change isn’t yet being pursued, and preparation is about planning to take action.
