Robert J. Gatchel PhD, ABPP

Robert J. Gatchel received his BA in Psychology, Summa Cum Laude, in 1969 from the State University of New York at Stony Brook, and his Ph.D. in Clinical Psychology in 1973 from the University of Wisconsin. A 2017 winner of the Gold Medal for Life Achievement in the Application of Psychology, he is also a Diplomate of the American Board of Professional Psychology (ABPP). Dr. Gatchel is currently the Chair and Distinguished Professor of the Department of Psychology, College of Science, at The University of Texas at Arlington, as well as the Nancy P. & John G. Penson Endowed Professor of Clinical Health Psychology. In addition, he is a Clinical Professor at The Eugene McDermott Center for Pain Management, Department of Anesthesiology & Pain Management, at The University of Texas Southwestern Medical Center at Dallas, as well as the Director of Biopsychosocial Research at the University of North Texas Health Sciences Center, Ft. Worth. Before joining The University of Texas at Arlington faculty in 2004, he was the Elizabeth H. Penn Professor of Clinical Psychology, Professor in the Departments of Psychiatry, Anesthesiology & Pain Management, and Rehabilitation Psychology, all at The University of Texas Southwestern Medical Center at Dallas, for 15 years. Dr. Gatchel has always been involved in new “cutting edge” areas of science and medicine. Three specific examples should be noted. First, he published the initial text in Health Psychology with Dr. Andy Baum (An Introduction to Health Psychology). In the Foreword of the text’s second edition, Dr. Jerome Singer described their efforts as follows: “…they had the opportunity to help structure a new field. To the extent that textbooks now copy the format of previous successful books, texts that follow theirs would adopt their organization, and, in pragmatic fashion, the field would be defined by what was in their textbooks.” The fourth edition of the text is now in preparation. The second example concerns the functional restoration approach to chronic pain and disability. Along with Dr. Tom Mayer at the Productive Rehabilitation in Dallas for Ergonomics (PRIDE), they were the first to introduce this interdisciplinary functional restoration approach. Functional restoration has been shown to be therapeutically effective in numerous independent clinical studies, and is now widely used, both nationally and internationally, for chronic pain management. Finally, Dr. Gatchel has been a major advocate for the biopsychosocial approach to chronic pain. This approach is now viewed as the most heuristic model for better understanding the etiology, assessment, treatment and prevention of chronic pain. Dr. Gatchel has conducted extensive evidence-based clinical research, much of it continuously funded for the past 30 years by grants from the National Institutes of Health (NIH). He was also the recipient of consecutive Research Scientist Development Awards from NIH, and a prestigious Senior Scientist Award from NIH. His major areas of clinical and research expertise involve the following: the biopsychosocial approach to the etiology, assessment, treatment and prevention of chronic stress and pain behavior; the comorbidity of physical and mental health disorders; and clinical health psychology. He has published over 240 journal articles, 100 book chapters and has authored or edited 23 books, including Psychological Approaches to Pain Management: A Practitioners Handbook, 2nd Edition (with D. Turk), Occupational Musculoskeletal Disorders: Function, Outcomes and Evidence (with T. Mayer & P. Polatin), The Psychology of Spine Surgery (with A. Block, W. Deardorff & R. Guyer), Clinical Health Psychology and Primary Care: Practical Advice and Clinical Guidance for Successful Collaboration (with M. Oordt), and Clinical Essentials of Pain Management. Dr. Gatchel is also featured in the Assessment of Pain, which is part of the APA Psychotherapy Videotape Series III, “Behavioral Health and Health Counseling” (2002). Dr. Gatchel has also received numerous awards and honors associated with his work in pain assessment and management, including the following: the Volvo Award for Low-Back Pain Research in 1986 from the International Society for the Study of the Lumbar Spine (which is the preeminent international research society for the study of painful spinal disorders); a 1994 Research Award from the North American Spine Society (NASS); the Award for Significant Contributions to Health Psychology, APA Division 38, 1997; the first psychologist to be honored with NASS’ 2001 Henry Farfan Award for Outstanding Contributions to the Field of Spine Care; Award for Outstanding Contributions to the Academy of Behavioral Medicine Research, 2002; the Award for Significant Contributions to the Field of Temporomandibular Joint and Occlusion Research, 2003; Visiting Scholar Program Awardee, Liberty Mutual Research Center for Safety and Health, Summer 2003; the 2003 Award for Outstanding Contributions to Science from the Texas Psychological Association; the 2004 Award for Distinguished Professional Contributions to Applied Research from the American Psychological Association; and the 2006 John Liebeskind Pain Management Research Award from the American Academy for Pain Management. The citation of one of his recent awards (the 2004 Award from the American Psychological Association) best summarizes his impact in the fields of pain and medicine: “For exceptional and pioneering research and training in clinical psychology. Robert J. Gatchel’s research has strengthened the biopsychosocial approach to physical and mental health disorders and made possible the early identification and successful treatment of patients at risk for the development of chronic pain. He has led many in the medical profession to carefully consider salient psychological and social factors. His tireless leadership in the area of health psychology has inspired his colleagues in the field of psychology and numerous medical specialties. Most important, his work has led to the amelioration of suffering and disability of thousands of people.” Finally, Dr. Gatchel has been a major participant in science and pain management education. To date, he has trained and mentored 65 Ph.D. graduate students, 6 postdoctoral Fellows, 32 Masters level students, and numerous junior faculty members. Many of these have gone onto prestigious careers in academia and pain management.
