[Psychodynamically oriented inpatient psychotherapy of depressive disorders - First findings from a naturalistic, multicenter study].

Objectives: While the general effectiveness of psychodynamic psychotherapy in both outpatient and inpatient treatment has been proven, few studies document the effectiveness of clinical inpatient treatment of depression through psychodynamic psychotherapy.

Methods: This paper presents first results of a naturalistic multicenter intervention study. Included were female inpatients suffering from depressive symptoms who had been admitted to 15 psychodynamically oriented psychosomatic hospital units (N = 487). The mean duration of treatment was 61.8 days. Data were acquired at admission (T1) and discharge (T2).

Results: Our findings support previous evidence and show that psychodynamically oriented inpatient psychotherapy of depressive disorders is efficient. High pre-post effect sizes were documented in all psychometric instruments used (BDI, HAM-D, SCL-90-R, BSS, GAF). Initial subgroup comparisons reveal that the benefits for patients with comorbid personality disorder are significantly lower than for depressed patients without comorbid personality disorder.

Conclusion: Psychodynamic inpatient psychotherapy, as practiced under naturalistic conditions, is an effective treatment of depression. Predictors of therapeutic effects within different therapeutic settings, however, remain unclear. The sustainability of the therapeutic effects found and their impact on psychodynamic relevant constructs have still to be proven.
