The concept of self-efficacy is integral to understanding behavior change, but it is not classified as one of the Stages of Change in the Transtheoretical Model. Instead, self-efficacy refers to an individual's belief in their ability to succeed in specific situations or accomplish tasks, and it plays a supportive role throughout the stages of change.

The Stages of Change in the Transtheoretical Model include precontemplation, contemplation, preparation, action, and maintenance. These stages represent the various steps individuals go through when modifying behavior. For example, in precontemplation, individuals are not yet considering change, while in action, they are actively making the change, and in maintenance, they work to sustain that change over time. Recognizing that self-efficacy influences how people progress through these stages can be valuable, but it does not belong to the stages themselves.
