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 GGON app for 15 days are, at the primary level: decrease in the degree of ascription to dysfunctional beliefs associated with ON; and at the secondary level: decrease in orthorexia nervosa symptomatology, in eating symptomatology and in obsessive beliefs; increase in self-esteem; and no changes in drepessive symptomatology. 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., conditionsModule conditions: Orthorexia Nervosa, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: CROSSOVER, interventionModelDescription: All participants were requested to complete web-based assessment, with questionnaires relating to maladaptive beliefs associated with ON, ortorexia, eating and depressive symptomatology, obsessive belifs and self-esteem at baseline (T1).The experimental group started using the app for 15 days, and later completed the following assessment (T2).
