Which stage in the Transtheoretical Model involves an individual taking concrete steps toward behavior change?

In the Transtheoretical Model, the Action stage is characterized by an individual actively engaging in specific, overt efforts to change their behavior. This stage follows the Preparation stage, where the person has made plans and is ready to implement those plans. During the Action stage, individuals implement their intention to change, demonstrating behaviors that align with their goal.

For example, someone trying to quit smoking would not only plan to do so but would also begin the process of tapering off nicotine, seeking support, or using cessation aids. This stage is crucial because it reflects the transition from intent to real behavioral change.

The other stages focus on differing aspects of behavior change: Precontemplation involves a lack of awareness or interest in changing, Contemplation signifies awareness and consideration of change but without taking action, and Preparation represents planning and strategizing for change but not yet executing the specific behaviors. Thus, the Action stage is specifically involved with the commitment to and execution of behavior change.
