简要总结
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).

主要结局
Change of eating attitudes and behaviors
时间窗: 16 days
Eating Disorder Inventory-3 (EDI-3; Garner, 2004; Italian version by Giannini et al., 2008): a self-report questionnaire assessing eating disorders core features made up of 91 items on a 6-point Likert scale (from always to never), with higher scores indicating higher eating disorder symptoms. It contains three primary subscales: Drive for Thinness (score range = 0-28; higher scores indicating higher drive for thinness), Bulimia (score range = 0-32; higher scores indicating higher bulimic symptoms), and Body Dissatisfaction (score range = 0-40; higher scores indicating higher body dissatisfaction). These subscales compose the Eating Disorder Risk Composite (EDRC) score. The other nine additional scales are Low Self-Esteem, Personal Alienation, Interpersonal Insecurity, Interpersonal Alienation, Interoceptive Deficits, Emotional Dysregulation, Perfectionism, Asceticism, and Maturity Fears.

Assessed with the Questionario sul Dismorfmismo Corporo (Questionnaire about Body Dysmorphic Disorder; QDC; Cerea et al., 2017), a self-report questionnaire assessing body dissatisfaction and body dysmorphic disorder symptoms made up of 40 items. Items are rated on a 7-point Likert scale (from 1 = strongly disagree to 7 = strongly agree; score range: 40-280), with higher scores indicating extreme body dissatisfaction and body dysmorphic disorder symptoms. Individuals who score above the cut-off of the questionnaire (QDC total score = 130) should be referred for further assessment because they might present extreme body dissatisfaction/body dysmorphic disorder symptoms or may be at risk of developing body dysmorphic disorder
