Mobile App for Eating Disorders in Adolescents

This study aims to evaluate the effectiveness of GGTCA-AD to decrease the maladaptive beliefs associated with eating disorders (ED) in non-clinical adolescent population. Specifically, a randomized controlled trial with parallel design and two groups (experimental and control) will be carried out in adolescents aged 13-15 years to assess the changes pre and post use of the app. It is expected that after the use of the GGTCA-AD app for 14 days, at the primary level, a: decrease in the degree of ascription to dysfunctional beliefs associated with ED; and at the secondary level: increase in body satisfaction and self-esteem; decrease in eating symptomatology; and no changes in emotional symptomatology. These results are also expected to be maintained in subsequent follow-up at 1 month.
