James Prochaska

James Prochaska is a psychologist best known for developing the Transtheoretical Model of Change, which outlines how people progress through stages when modifying behavior, such as quitting smoking or adopting healthier habits. His model identifies five stages: Precontemplation, Contemplation, Preparation, Action, and Maintenance. This framework helps understand that change is often a gradual process and varies for each individual, emphasizing the importance of tailoring interventions to fit a person's current stage in order to facilitate successful behavioral change. Prochaska's work has significantly influenced health psychology and behaviors related to wellness.
