Brief Summary

200 persons with depression are recruited via internet depression forums devoted to depression and are randomly assigned either to the online program deprexis or to a wait-list control condition. All participants receive free-of-charge online access to deprexis either immediately or with an eight week delay. Prior to intervention and eight weeks later, both groups are assessed via an anonymous online survey which was implemented using the software package OPST®. The survey consists of different questionnaires. The Beck Depression Inventory (BDI) represents the primary outcome. It is assumed that the severity of depressive symptoms will improve to a significantly greater extent in the deprexis than in the wait-list control condition in the course of eight weeks.
