James O. Prochaska, PhD

Director of the Cancer Prevention Research Center

Professor of Clinical and Health Psychology
University of Rhode Island

James O. Prochaska, PhD, is Director of the Cancer Prevention Research Center and Professor of Clinical and Health Psychology at the University of Rhode Island. Prochaska is internationally recognized as co-creator (with Carlo DiClemente, PhD) of the Transtheoretical Model of Change, a model that identifies stages of change and other factors that predict treatment outcomes and allows many more people to enter cessation programs at earlier stages of readiness.

The Transtheoretical Model recognizes that behavior change involves a process; previous theories saw change as equaling action, and only measured success if someone stopped smoking or abusing alcohol. The model has revolutionized substance abuse prevention and treatment and has been adopted around the world.

Prochaska is the author of more than 200 publications including three books: Changing for Good, Systems of Psychotherapy, and The Transtheoretical Approach. He is the principal investigator on more than $60 million in research grants for the prevention of cancer and other chronic diseases. He has served as a consultant to the American Cancer Society, Centers for Disease Control and Prevention, National Health Service of Great Britain, health maintenance organizations, major corporations and numerous universities and research centers.

Prochaska has won numerous awards including the Top Five Most Cited Authors in Psychology from the American Psychology Society, an Honorary Chair of Medicine from the University of Birmingham, England, and the Society of Prospective Medicine L.C. Robbins Award for Career Contributions to Health Promotion. He has been cited by the American Psychology Society as the most influential author in clinical and health psychology. He is a fellow of the American Psychological Association and the Society of Behavior Medicine.

Prochaska received his BA in Psychology and Sociology and both his MA and PhD in Clinical Psychology from Wayne State University in Detroit, Michigan. He was a US Public Health Service Predoctoral Clinical Fellow while completing his Masters at Wayne State, and a Woodrow Wilson Fellow at Clark University (Worcester, Massachusetts), where he studied immediately after receiving his BA.

A Professor of Psychology at the University of Rhode Island (URI) since 1969, Prochaska holds a number of additional URI appointments including: Director of the President's Health Promotion Partnership; Director of the Cancer Prevention Research Consortium; and Director of the Self-Change Laboratory. He currently chairs Pro-Change Behavior Systems, LLC, and until recently had a private practice in clinical psychology in Kingston, RI.

Prochaska is one of five individuals selected to receive The Robert Wood Johnson Foundation's Innovators Combating Substance Abuse award in 2002.
