A Mobile-App Training to Reduce Body Image Disorder Symptoms and Associated Features in Female University Students

Body dissatisfaction represents a prevalent condition in young women, and it is associated with low self-esteem, depression, and symptoms of Body Dysmorphic Disorder (BDD) and Eating Disorders (EDs). The aim of the trial is to test the effect of a mobile health application called "GGBI: Positive Body Image" in reducing body dissatisfaction, body dysmorphic disorder/eating disorder symptoms, and associated psychological features in female university students considered at high-risk of developing Body Image Disorders (BIDs). Hypothesis: Participants using "GGBI: Positive Body Image" immediately following baseline assessment (Time 0; T0) (immediate-use App group: iApp) would exhibit greater reduction in body dissatisfaction, body dysmorphic disorder/eating disorder symptoms, and associated psychological features than participants who did not use "GGBI: Positive Body Image" in this phase of the study (delayed-use App group: dApp). Following crossover (Time 1; T1), the investigators expect that participants gains in the iApp group would be maintained at follow-up (Time 2; T2).
