Brief Summary
This is a cluster randomized controlled trial with two assessment points (baseline and 24-week follow-up) comparing the Claudia Carraro prevention program to a no-intervention control group. The intervention group was also assessed at post-intervention. To ensure that all students benefit from the intervention, the control group received the intervention after the 24 weeks. Randomization was performed at the school level, not the student level.

Outcome Measures
Primary Outcomes (1)
Eating Disorder Examination Questionnaire
The Eating Disorder Examination Questionnaire (EDE-Q) (Calugi et al., 2017; Fairburn et al., 2008) is a validated Italian version that assesses the severity of eating disorder psychopathology over the past 28 days. The EDE-Q assesses eating disorder psychopathology with a global score and four subscales (restraint, eating concern, weight concern, shape concern) and eating disorder behaviours (objective binge-eating, self-induced vomiting, laxative misuse, excessive exercise). Scores range from 0 to 6. Higher scores indicate higher eating disorder psychopathology.
Baseline and 24-week follow-up. The intervention group was also assessed at post-intervention
Secondary Outcomes (2)
Short Form of the International Physical Activity Questionnaire
Baseline and 24-week follow-up. The intervention group was also assessed at post-intervention
Mediterranean Diet Adherence Questionnaire
Baseline and 24-week follow-up. The intervention group was also assessed at post-intervention
Study Arms (2)
Intervention
EXPERIMENTALThe intervention arm, includes studed who attended the "Claudia Carraro" prevention program. It is grounded in a cognitive-behavioral conceptualization of the development of eating disorders or disordered eating. The program was designed to address specific and non-specific risk factors that appear relevant: body dissatisfaction and unhealthy weight control behaviors. Its dual objective is to help participants reduce the importance they place on body weight and shape in self-evaluation while simultaneously promoting healthy weight regulation through adherence to Mediterranean dietary guidelines and an active lifestyle. The strategies and procedures used are derived from cognitive behavioral therapy protocols for eating disorders (Dalle Grave \& Calugi, 2020). The intervention is delivered by psychologists specialized in eating and weight disorders using an interactive, rather than didactic, format, involving small group activities and assigned homework tasks between sessions.
Control
NO INTERVENTIONNo intervention. The control group received the intervention after the 24 weeks
