iFighDepression is an online self-help programme for mild to moderate depression that has been developed in the context of the European project Preventing Depression and Improving Awareness through Networking in the European Union (PREDI-NU) which is managed by the European Alliance Against Depression (EAAD). It involves the most complete integration of the cognitive-behavioral online programs available to date, which is a format of intervention that has been proven effective in reducing depressive symptoms in several randomized controlled trials. IFightDepression is currently in pilot phase in 7 European Union countries, including Spain.
