One indication of his range of clinical and research experience is his Fellow status with the American Psychological Association in not one but four divisions: Psychotherapy, Clinical, School, and Family Psychology.

His distinguished career has spanned nearly five decades. He has promoted the recognition of anger as a form of psychopathology, and studies the diagnosis, assessment, and treatment of persons with anger problems. He has developed standards for identifying anger diagnostic disorders. Professor DiGiuseppe has published more than 120 scientific papers and book chapters and is a co-editor of the Journal of Rational-Emotive and Cognitive-Behavior Therapy as well as two psychological tests assessing dysfunctional anger:

  • the Anger Disorders Scale (ADS) for adults and
  • the Anger Regulation and Expression Scale (ARES) for children and adolescents.

He works on the development of the theory, practice, and empirical research support of Rational Emotive Behavior Therapy and Cognitive Behavior Therapies. He is presently developing measures of Ellis’ concept of irrational and rational beliefs and their relationship to other cognitive behavior constructs and emotional disturbance.

A popular conference speaker, Professor DiGiuseppe pioneered popular presentation formats, such as the Master Clinician Series and World Rounds.
