Cognitive Intervention via Mobile App for Eating Disorders: An Exploratory Case Series in Remission-Phase Patients

Relapse following treatment is a frequent occurrence in individuals with eating disorders (EDs), highlighting the importance of developing preventive interventions. The GG Eating Disorders (GGED) module is designed to address dysfunctional beliefs that contribute to the development and maintenance of these disorders through its use within a mobile application. The aim of this exploratory case series study is to analyze the efficacy of GGED in reducing ED-related dysfunctional beliefs and eating symptomatology and increasing body satisfaction and self-esteem among three patients with EDs in remission. Following the use of GGED, patients showed a decrease in most dysfunctional beliefs and ED symptoms, accompanied by an increase in body satisfaction and self-esteem. However, these changes did not reach clinical significance in all patients. The GGED module has the potential to serve as a very useful tool in maintaining cognitive changes following cognitive behavioral therapy and thus preventing relapse.Clinical Trial Registration: This study was registered with ClinicalTrials.gov (Identifier NCT06842862).
