Raymond A. DiGiuseppe
Who They Are
Raymond A. DiGiuseppe is a clinical psychologist, major REBT theorist, and trainer with over 47 years of involvement in teaching REBT. He was trained directly by Albert Ellis and worked closely with him, making him one of the foremost authorities on REBT theory and practice.
DiGiuseppe holds advanced training credentials in REBT and has been instrumental in codifying REBT skills, conducting research on irrational beliefs, and developing deliberate practice exercises for REBT training.
Key Contributions
- Irrational belief research: Conducted research demonstrating that certain irrational beliefs (e.g., global evaluation of self) stand alone as independent and particularly powerful belief constructs (DiGiuseppe et al., 2020)
- Training expertise: Co-leads training at the Albert Ellis Institute; develops curriculum and supervises trainee therapists
- Deliberate practice in REBT: Co-authored Deliberate Practice in Rational Emotive Behavior Therapy, translating decades of REBT training experience into structured practice exercises
- Emphasis on procedural fluency: Advocates for trainees developing automatic, flexible access to REBT skills under stress—not just intellectual understanding
Clinical Orientation
DiGiuseppe emphasises:
- Precision in identifying beliefs: Careful distinctions between inferences and evaluative beliefs
- Strategic sequencing: Teaching REBT skills in a purposeful order that builds from foundational to advanced
- Practice and repetition: Moving skills from declarative to procedural knowledge through deliberate practice
- Flexibility and personal style: Encouraging trainees to integrate REBT principles into their own authentic therapeutic voice
Influence on Integrative Practice
DiGiuseppe’s work helps integrative practitioners by:
- Clarifying what distinguishes REBT from other CBT approaches (especially the emphasis on evaluative beliefs and philosophy)
- Providing empirical support for core REBT constructs through research
- Demonstrating how REBT training can be systematic and skill-based
- Showing how REBT aligns with and complements other frameworks
