[Day-clinic and Inpatient Psychotherapy of Depression (DIP-D)--Secondary Outcomes and Follow-up Results of a Randomized-Controlled Pilot Trial].

Depressions are frequent disorders in psychosomatic medicine and psychotherapy. However, there are only few controlled studies comparing different levels of care for depressed patients. Especially the efficacy of day-clinic psychotherapy for depression remains understudied. The pilot study aims to close this gap by examining the feasibility of a randomized-controlled trial comparing day-clinic and inpatient psychotherapy for depression in a routine hospital setting. The current paper adds the secondary outcome measures on patient self-reported symptoms and interpersonal problems. In addition, findings of a 6-month follow-up are analyzed. Overall, 44 patients were recruited and randomly allocated to either day clinic or inpatient psychotherapy for 8 weeks. Depressive symptoms and interpersonal problems decreased during treatment, and follow-up scores stayed below intake scores. There were no differences between the treatment groups in this pilot study. For the future, it is desirable to compare randomized patients with those patients who received their preferred treatment option. Although the findings need to be replicated in larger samples, they appear promising for day-clinic psychotherapy. The better understanding of differential effectiveness of different levels of care of patient subgroups remains an important goal.
