What is psychotherapy about? What are the similarities and differences of its many forms? What are the most recent developments in the field? Introduction to Psychotherapy has been an essential reference book since its publication in 1979, and is regularly included in reading lists for trainee psychotherapists, psychiatrists and other professionals. It is often recommended to interested lay people and prospective patients. This third edition takes into account recent changes in psychotherapy theory, practice and research. The authors are all psychoanalysts. The first edition arose from the experiences of Dennis Brown and Jonathan Pedder working and teaching together as Consultant Psychotherapists at St Mary's Hospital and Medical School, London.
