This is the Third Edition of the best-selling self help psychotherapy program for lay people and students of psychotherapy since first publication in 1990. The book is based upon Cognitive Analytic Therapy, a focused short term intervention pioneered and researched at Guy's and St. Thomas' Hospitals in London since the early 1980's by Dr. Anthony Ryle, and now taught and practiced throughout the UK and abroad. The book describes in ordinary language how learned patterns of responses to relating and thinking contribute to psychological problems such as depression, anxiety, phobia, and relationship difficulty. The book shows the reader how they can identify their own different inner dialogues, and the traps, dilemmas, snags, and unstable states of mind that lead to things going wrong. It offers help with the creation of written narrative and diagrams based upon the readers' own self reflection. Mindfulness-based experiential exercises are incorporated throughout the text to help nourish self awareness and change. The new edition offers a therapeutic dialogic relationship between reader and author. It includes the most recent development in CAT practice and places greater emphasis upon the transformation of unhelpful learned reciprocal role procedures that underlie relationship to oneself and to others. Change in symptoms occur when new and beneficial reciprocal roles are created. The book covers many areas of emotional distress, and the Third Edition also includes new chapters on unstable states of mind seen in people given a borderline personality diagnosis, on dissociation, eating problems, and stress.
