This dictionary provides definitions of key terms, concepts and major treatment techniques associated with Rational Emotive Behaviour Therapy (REBT). Though it will be of most use to practicing REBT therapists, cognitive-behavioural therapists, and trainees in REBT and CBT, it will also be of interest to the more general reader. Providing a concise but comprehensive explanation of the theory and practice of REBT, the dictionary is best used as an essential adjunct to more general texts on REBT. However, the authors also hope that the book will be valuable in itself as a summary of current REBT wisdom.
