Transactional Analysis (TA) has continued to grow and develop ever since its inception by the Canadian-American psychiatrist Dr. Eric Berne over a half century ago. It has proven itself to be an extremely useful model for human relations professionals working in a variety of contexts and fields, such as psychotherapy, coaching and counselling, management and organizational development, or parenting and education. This book is for anyone who wants to further deal with the theory and practice of TA knowledge. The book also provides a lot of information for professionals who already use TA. Because of the many examples and the layering of each chapter both beginners and experienced professionals will find much of interest and use in this textbook.
