Transactional Analysis (TA) - an explanation

TA is a therapy modality used to create growth and change. The late Eric Berne developed the concepts and tools of TA and introduced them to the public in his book "Games People Play." Berne referred to TA as social psychiatry, meaning a form of therapy or counseling used by every day people. The concepts of TA are simple to understand, straight forward and user-friendly but above all not full of medical terminology or psycho-babble. When applied, the tools and understanding provided by TA can create positive change to people, relationships, and the work environment (QWL or quality of work life).

The name of the modality really describes at the simplest level what TA is, the analysis of a transaction. Of course, to understand the concept fully, you need to know that a transaction is a communication between two or more people. TA is a theory of communications and interpersonal interaction. Sometimes the communications between two people have a hidden message, meaning and agenda. The result of this hidden message is a game. The purpose of the game is to get a need met, without asking directly for what we need or want. We learned how to play these games to get our needs met as children, and they worked then. But as adults, they can become the source of problems in our every-day relationships with ourselves and those around us.

TA is also a theory on personality and psychological structure. The concept of the PARENT, ADULT, and CHILD ego states also originated in TA. These ideas help us to understand, explain and change our behavior and have better relationships with others. Through these ideas, we begin to understand ourselves and how we operate, as well as others.
