Study of the Efficacy of GGED: a Cognitive Training App for Eating Disorders.

The intervention will be done through an app named GGED, which is used to work on the dysfunctional beliefs that are associated with eating disorders. The app is made up of a series of levels comprising the topics that are normally worked on in CBT in relation to eating disorders. At each level, affirmations in the form of beliefs appear on the screen, and the person must accept them if they are functional, adaptive and positive; or reject them if they are dysfunctional, maladaptive and negative.
