Title: Evaluation of the Effectiveness of a Web-based Treatment Program for Depression (Deprexis) for the Reduction of Depressive Symptoms in Patients With Multiple Sclerosis and Epilepsy. A Randomized Controlled Trial
Brief Summary: 200 persons (100 with multiple sclerosis and 100 with epilepsy) with depressive symptoms are recruited via the multiple sclerosis clinics of the University Medical Center Hamburg-Eppendorf and the epilepsy centre Alsterdorf and 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 a six month delay.

At three time points (1. prior to intervention, 2. after completion of the intervention nine weeks later and 3. at follow-up six month 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 (IIT analysis for pre versus post). 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 nine weeks and will be maintained in a six month follow-up.
