In this new edition published by Sage, An Introduction to Transactional Analysis introduces the theory and practice of Transactional Analysis (Ta) which integrates cognitive behavioral and psychodynamic theories within a humanistic philosophy. While most Ta books focus on one field, this approach demonstrates the benefits of Ta across a wide variety of settings, business and management, education and coaching as well as counseling. Case studies from a variety of contexts bring Ta to life for practitioners in any of these disciplines, and the accessible, engaging writing style makes difficult concepts understandable for undergraduates and postgraduates. Bringing their book into the twenty-first century, the authors provide a brief history of Ta followed by individual chapters on the concepts and techniques used with detailed definitions and descriptions, and suggestions for application in practice.
