It was only after Dr Eric Berne''s Games People Play became in international bestseller in 1964, that transactional analysis, his highly original and innovative approach to psychotherapy, attained wide recognition outside the United States. Over the past forty-five years, however, the principles and practice of ''t.a.'' have intrigued not only professional therapists but all those who seek to understand human personality and the peculiarities of human relationships.Transactional Analysis in Psychotherapy, the book in which he first laid out the principles of his method, has become a classic in its field and is now available to a new generation of readers.
