Carlo C. DiClemente (Psychologist)

Carlo C. DiClemente is an American psychologist best known for his work in understanding behavior change, particularly regarding addiction and personal motivation. He developed the Transtheoretical Model (TTM), which outlines how people move through stages when changing behaviors, such as quitting smoking or improving health. The model identifies five stages: precontemplation, contemplation, preparation, action, and maintenance. DiClemente's research emphasizes that change is a gradual process and not a linear journey, helping therapists and individuals understand and facilitate effective behavioral changes. His work has had a significant impact on counseling and health promotion practices.
