Depression
Conditions
Brief summary
The purpose of this study is to determine the acceptance and efficacy of the online self-help program deprexis® for depressed patients in reducing the clinical symptoms of their depression. The patients of the experimental group use deprexis® for 90 days, the patients of the placebo group receive weekly online information about depression for 90 days as well. Both groups receive their treatment in addition to their regular inpatient psychosomatic treatment and as an aftercare intervention.The investigators hypothesize that the online self-help group achieves a greater reduction of depression compared to the control group.
