"The main theoretical and practical applications of Rational Emotive Behavior Therapy (REBT) and Cognitive Therapy (CT) are examined and found to be similar to each other in most respects, but REBT bases its concepts of improved treatment of neurotic disorders and of severe personality dysfunctioning largely on philosophical, existential, and humanistic bases, while CT tends to align them with empirical results of outcome studies. Both REBT and CT, however, use philosophic and empirical outcome studies to construct and validate their theories." (Ellis, A. Similarities and Differences Between Rational Emotive Behavior Therapy and Cognitive Therapy. Journal of Cognitive Psychotherapy;Fall2003, Vol. 17 Issue 3, p225).
"REBT works more on the nature of B rather than on the mere content of B as does CT. This leads to greater generalization of therapeutic gains including insight, awareness, feeling, and behavioral change. For instance, if, as in CT, you focus on the content of the B rather than on the nature of the B, then you must approach each B individually and you learn only to dispute similar Bs from disputing one particular B. However, if, as in REBT, you focus on the nature of the B, then you can approach any B with the same fundamental tests for rationality, for helpfulness, for logic, for reality. Tests such as flexibility, extremeness, and demandingness can be applied generally. While such tests also are developed in CT, they are developed less efficiently, effectively, and forcefully because they are side effects rather than goals when challenging Bs."

"Cognitive Therapy and RET have a lot in common both in theory and practice but have some major differences as well. My view is no doubt biased, but RET appears to rely on the therapist confronting the client and convincing the client that his or her beliefs are irrational. It often sounds as though RET believes that rational thinking will eliminate all problems. In Cognitive Therapy we try to work with the client to help them to look critically at their perceptions and beliefs and help them to identify and modify the perceptions and beliefs which contribute to their problems. We also focus on much more than just cognition. It is often important to help clients master the skills they need to cope with problematic situations, to help them cope with intense emotions, and to help them change (or leave) dysfunctional relationships."

"REBT advocates an early focus on irrational cognitive schemas whereas other approaches to CBT will tend to focus on more surface cognitions before dealing with underlying schemas." (Neenan & Dryden, http://www.sagepub.com/upm-data/36870_Neenan_&_Dryden_(REBT)_2e_CH_01.pdf)
"Here is a practical example to understand the difference:
Think about a guy who avoids going out socially because he is afraid that he might not fit in and people won’t like him. In CBT, the therapist asks questions like how do you know you won’t fit it or be liked? Can you think of similar situations where you were liked or you did fit in? Maybe this time things will be different? What are some of your strengths that people would notice and like?” etc. As you can begin to see, the focus is getting the client to believe that if he did go out, he would likely be successful in that at least some people would probably like him.
In REBT, the client would be asked, “So let’s suppose that you did go out and you didn’t fit in that well and no one liked you. What is so AWFUL about that? Do you need to base how you feel about yourself on what others think about you? Could you imagine just being disappointed rather than a major catastrophe if your worst concerns about going out turned out to be true? As you can begin to see, REBT seeks to attack the underlying negative core beliefs associated with the individual’s sense of self worth."
