Transactional Analysis (TA) is a theory of personality and psychotherapy to achieve personal growth and autonomy, developed by Eric Berne (Jones in Steward, 2015). TA can be used where we want to understand the human psyche, communication and relationships between people. It is applied in the treatment of various psychological problems (anxiety, depression, personality disorders, etc.).  Transactional analysis integrates psychoanalytic and cognitive-behavioural therapy within the framework of the humanistic existential orientation. Transactional Analytical Psychotherapy has a long history, and its latest model is developmental relational, meaning that the key focus is on dealing with what is happening at the interpersonal level between the therapist and the client here and now (Clarkson, 2013).

Working with a child through process diagnostics is aimed at establishing a secure relationship that enables the child to satisfy important relational needs which were not recognized and adequately met in previous relationships. An individual gets a new experience of a secure relationship. The essence is the construction of the child's and adolescent's self-awareness and autonomy (Hargaden and Sills, 2014).
