This article analyzes the opportunities and limitations of working with a life scripts within the framework of an integrative approach in transactional analysis. This is illustrated and shown by the example of a practical case of working with a client. The integrative approach in transactional analysis claims to be a comprehensive and in-depth study of the life scripts, including the body level, and is consistent with the latest research in neuroscience, in the field of building contact and therapist-client relationships. Using this approach, the script is worked through gently and deeply at four possible levels: survival reactions, implicit and explicit memory, and introjects. Script cure happens in four directions: cognitive, affective, bodily, and behavioral. The script with this approach is carefully and deeply worked out at four possible levels: survival reactions, implicit and explicit memory, introjects. The healing of the script takes place in four directions: cognitive, affective, bodily and behavioral. The script system as a tool in practice allows psychologists and psychotherapists in practice to approach life script healing systematically and at all the levels simultaneously, to better understand the intrapsychic functions of the script and begin to heal through the relationship from the very first meetings with a client. The article will compare and analyze the classical Keyhole model, which brings together all the methods of the integrative approach and the sequence of the therapy process, and its adapted version intended to be used with the Brainspotting method, in order to show by example the limitations of the integrative approach methods when applying the classic model and how they can be overcome in practice.
