Transactional Analysis Psychotherapy is the first advanced textbook for psychotherapists and counsellors who use the theory and techniques of Transactional Analysis in their practice. Clarkson provides a comprehensive guide to goal-setting and clinical planning for every stage of treatment; problems of technique are illustrated throughout by clinical vignettes and case material. At the theoretical level, the author represents Transactional Analysis as contemporary psychotherapy based on the classical work of Eric Berne and predecessors such as Federn, Fairbairn, and Klein, which integrates humanistic/existential philosophy with behavioural pragmatism. This is not only a practical textbook relevant to modern developments in supervision but one which makes a new and original contribution to ways of thinking about transference and countertransference, the theory of self, and the process of psychotherapeutic change. It is intended as a bridge between Transactional Analysis and other theories of psychotherapy and is of particular relevance in today's climate of interdisciplinary communication.
