Which stage is NOT part of the Transtheoretical Model of Behavior Change?

The Transtheoretical Model of Behavior Change consists of several key stages that capture the progression individuals typically go through when modifying behavior. These stages include:

• Precontemplation: Individuals are not yet considering change.
• Contemplation: Individuals are thinking about making a change but have not yet committed.
• Preparation: Individuals are planning for change and may be making small steps toward it.
• Action: Individuals actively engage in behaviors to change.

Assessment, while an important concept in understanding an individual's readiness and motivation for change, is not a formal stage within this model. Instead, it often refers to evaluating an individual's current behavior and readiness to move through the stages but does not fit into the defined sequence of behavioral change stages identified by the model. Therefore, recognizing the specific stages is crucial for applying the framework effectively in interventions aimed at facilitating behavior change.
