Dr. DiTomasso in the News:


Dr. DiTomasso graduated with a BA in psychology magna cum laude in 1973 from La Salle University and then pursued and completed an MS degree in general-experimental psychology from Villanova University in 1975, where he was the recipient of a research assistantship. This was a rigorous program that provided a solid foundation in scientific psychology and, later, an empirical focus for his clinical work. It was at Villanova where Dr. DiTomasso took his first course in Behavior Therapy and discovered an area of study devoted exclusively to helping people through the use of empirically-derived techniques based upon learning principles - a perfect match for his interests.

The next year he entered the PhD program in professional-scientific psychology at the University of Pennsylvania and over the next four years he refined his interest in behavior therapy, cognitive therapy, and research methods. While at Penn he was awarded a teaching fellowship and was mentored in the art of teaching. Subsequently, he attended the June Institute in Behavior Therapy and completed an internship under the direction of Joseph Wolpe, MD at the Behavior Therapy Unit, Eastern Pennsylvania Psychiatric Institute, Temple University School of Medicine, Department of Psychiatry. Upon graduation from the University of Pennsylvania, he was awarded the William E. Arnold Dean's Award in recognition of outstanding leadership and scholarship. He later obtained postdoctoral training and supervision in cognitive-behavioral therapy and family therapy and completed a certificate in cognitive therapy under the direction of Arthur Freeman, EdD, ABPP.


Dr. DiTomasso's major areas of interest are cognitive-behavioral assessment, therapy, and consultation, anxiety and anxiety-related disorders, primary care psychology, patient non-adherence, developing assessment instruments for health risk behaviors, and research design, measurement, methodology and program evaluation. Over the past several years, Dr. DiTomasso and his dissertation students have been developing and studying a variety of new measures including The MAD-AS, an anger questionnaire, The Inventory of Cognitive Distortions (ICD), and the HABIT (Health Adherence Behavior Inventory.

He has mentored over 75 dissertation students during his tenure at PCOM. He has published 59 book chapters and articles and has delivered 45 professional presentations locally, regionally, national and internationally. He has also published four books including Specialty Competencies in Clinical Psychology. New York: Oxford University Press; The Handbook of Cognitive Behavioral Approaches in Primary Care.
