Group psychotherapy is common and useful disorder treatment process, especially using in outpatient system. The situation in stationary system such as mental hospitals and their acute departments is quite different, because it is more exacting work environment for group and therapists. The clinical observations shows that for great part of stationary system patients the psychodynamic group therapy is new experience. Hence it is very important to prepare therapeutic program which is well thought out and contains realistic goals. As the research shows, patients suffering for deeper pathology needs more safety and more compact therapeutic environment. Then they can make some substantial changes. Presented statistics of patients which was participating in this therapy (n 53) shows that although they have different diagnosis, more of them (64,2%) accomplished this process. Providing group psychotherapy in mental hospital department is exacting but possible task. Furthermore it is practicable and efficient method. Benefits both are strong for patients and for hospital (better realization of government schedule).
