The success of psychotherapy does not depend on luck or chance. According to Walther Cormann, there is an inner logic, a structure to successful therapeutic approaches. He describes step by step how the complex processes in systemic-integrative psychotherapy or counseling are structured, aligned with the five factors of effectiveness, and implemented in the form of the "counseling loop." Based on this, interventions can then be made creatively, playfully, vividly, emotionally, and humorously. The goal is to collaboratively develop new perspectives and better attitudes with the client and to promote a lasting positive sense of life. The five factors of effectiveness are: 1. The therapist's personality 2. The setting 3. The therapy and counseling loop 4. The methods 5. The shared responsibility of the clients. This is a training and further education book on systemic-integrative therapy and counseling.
