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 organisational development, or parenting and education. TA combines an accessible theory on the development of people and systems with a practical approach, centred on the possibilities of change, growth and development. Into TA is a comprehensive textbook of contemporary TA in theory and practice. The first section of the book focusses on theory, presented so that both beginning and experienced professionals will find much of value. TA theory is then further integrated with other current models of psychology, education, and organisational consultation. The second section provides rich and stimulating examples of TA in practice that bring the theory to life.
