Transactional analysis (TA) is a theory of personality, a language of behavior, and an organized system of interactional therapy. It is grounded on the assumption that we make current decisions based on our early experiences. Early in life we may have felt powerless or even experienced ourselves as struggling for survival. Decisions made then about how to behave may not be valid, useful, or empowering today. These early decisions may, in fact, be self-sabotaging. The TA therapist focuses on helping clients rethink and redecide these early decisions in light of present circumstances. TA emphasizes the cognitive and behavioral aspects of the therapeutic process. Within TA there are three recognized schools—classical, Schiffian (or reparenting), and redecisional and unofficial schools identified as self-reparenting and restructuring or corrective parenting. The redecisional school has gained in prominence and is the focus of this chapter.
