Since its launching in 1955, rational-emotive therapy (RET) has become one of the most influential forms of counseling and psychotherapy used by literally thousands of mental health practitioners throughout the world. From its beginnings, RET has dealt with problems of human disturbance. It presents a theory of how people primarily disturb themselves and what they can do, particularly with the help of a therapist or counselor, to reduce their disturbances. The evident popularity and clinical utility of RET in different cultures and its increasing application to contemporary problems of living indicate that rational-emotive therapy continues to be vital and dynamic.
Albert Ellis was an American psychologist who in 1955 developed Rational Emotive Behavior Therapy (REBT). He held M.A. and Ph.D. degrees in clinical psychology from Columbia University and American Board of Professional Psychology (ABPP). He also founded and was the President of the New York City-based Albert Ellis Institute for decades. He is generally considered to be one of the originators of the cognitive revolutionary paradigm shift in psychotherapy and the founder of cognitive-behavioral therapies. Based on a 1982 professional survey of USA and Canadian psychologists, he was considered as the second most influential psychotherapist in history (Carl Rogers ranked first in the survey; Sigmund Freud was ranked third).
