Intervention model description: All participants were requested to complete web-based assessment, with questionnaires relating to maladaptive beliefs associated with ED, eating and emotional symptomatology, body satisfaction and self-esteem at baseline (T1). The experimental group started using the app for 15 days, and later completed the following assessment (T2). The control group also completed the T2 in the same date but started to use the app after this second assessment.15 days and one month later, both groups completed T3 and T4.
Primary purpose: PREVENTION

Brief summary: The aim of the present study is to evaluate the efficacy of GGTCA to decrease the maladaptive beliefs associated with eating disorders (ED) in non-clinical adult population. Specifically, a randomized controlled trial with crossover assignment design and two groups (experimental and control) will be carried out in adults aged 18-65 years to assess the changes pre and post use the app. It's expected that after the use of the GGTCA app for 15 days are, at the primary level: decrease in the degree of ascription to dysfunctional beliefs associated with ED; and at the secondary level: increase in self-esteem; decrease in eating symptomatology; and no changes in emotional symptomatology, since the pilot study did not find. These results are also expected to be maintained in subsequent follow-ups, at 15 days and a month after to finish the app in experimental group, and 15 days after to finish the app in control group.

Detailed description: There is a digital platform called GGtude, which is composed of different modules, each of them aimed at working with different mental health problems. The goal is to provide an easy-to-use tool as a CBT complement to work on the self-dialogue that relates to the core beliefs associated with the psychological problem in particular. To achieve this target, a cognitive training exercise is performed: different sentences appear in the form of beliefs, and the person must identify and accept those beliefs that are functional, adaptive and positive, dragging them to the lower part of the screen; and reject those that are dysfunctional, maladaptive and negative dragging them to the upper part of the screen.

There are different modules, for example, to work self-esteem, depression, body image or obsessive-compulsive disorder, that have proven their effectiveness.
