This study evaluated the impact of psychodynamic inpatient psychotherapy on patients' psychological distress and interpersonal problems during the course of treatment and 1 year later. A total of 156 patients were assessed with the Symptom Checklist-90-Revised and the Inventory of Interpersonal Problems at intake, 4 weeks later, and at the end of therapy. The follow-up assessment was conducted 1 year later. Results support psychodynamic approaches as well as the phase model, which stresses that the goals to be achieved by psychotherapeutic interventions are not only improvement of well-being and symptoms but also changes in interpersonal behavior. Consequently, on a long-term basis, the first 4 weeks of therapy seem to be insufficient, especially for adequate changes on the interpersonal level.
