deprexis is a web-based software program intended to help patients with unipolar depression or depressive disorders to better cope with their depression or depressive disorder by offering them therapeutic methods and exercises in form of a self-application as a supplement to care-as-usual. deprexis uses the services of GAIA’s proprietary software platform broca® and can be used according to the user‘s preferences with any computer, laptop, smartphone or tablet with internet access and with an up-to-date version of one of the supported browsers. Users need an access code to register in deprexis. Users will enter the access code, and then set a password for subsequent logins. Once registered, deprexis guides users through the program in a dynamic dialogue. No special computer skills are required to use deprexis. The program will track progress and continue to guide the patient through the modules. Each module informs the patient when the session is completed. All information entered is private to the user. The user will additionally receive emails or text messages encouraging an active use of the presented information and exercises, and encouraging practice and integration of them into daily routines.
