Prochaska DiClemente Stages

The Prochaska DiClemente stages of change model evolved in a study of smokers who quit on their own, as opposed to smokers who required further treatment. The five stages of change are defined as precontemplation, contemplation, preparation, action, and maintenance. The sixth stage of change, adopted later, is defined as either relapse or termination. Thus, relapse or termination is less frequently used in the application of the stages of change model for health-related behaviors.

In the Prochaska DiClemente Stages, the therapist offers specific intervention strategies to move a person through each of the five stages of change. The ultimate goal is to achieve ongoing maintenance, the ideal stage of behavioral change. In teen substance abuse treatment, this translates as long-term sobriety.
