School-Based Disordered Eating Prevention Education Program
The intervention consisted of three student modules and one parent module. The first module focused on body image, body satisfaction, body acceptance, and the prevention of weight- and body-related peer bullying. It was delivered by a psychologist specializing in adolescent psychology and included scenarios, videos, and positive peer feedback activities. The second module addressed social media literacy, unrealistic appearance ideals, dieting myths, online information reliability, screen time, and family meals. The third module covered healthy and balanced nutrition, food groups, the balanced plate model, and physical activity, including a classroom-based plate activity. Previous session topics were briefly reviewed at the beginning of each module. Six weeks after the intervention, a 10-minute refresher session was delivered by the researcher, a dietitian. The parent session addressed eating disorders, their symptoms and risk factors, and healthy nutrition principles.
