Originally published in 1984, this was the first book by a British author on this subject and it brings together all the author’s previous work in this area. Its unique character is that it presents both the fundamentals, based on the work of Ellis, and innovations, developed in part by the author, extending this work. The book therefore combines theory and practice and will be of interest to those in counselling, clinical psychology, psychiatry and social work, as well as those in nursing and occupational therapy.
