 Women in general and young girls in particular are constantly exposed to unhealthy body and appearance ideals through media that contribute to body dissatisfaction and unhealthy behaviors such as rigid dieting, which in interaction with genes and other factors increase the risk of developing eating disorders such as anorexia nervosa and bulimia nervosa. The investigators aim is to investigate the extent to which an interactive prevention program, delivered through Internet, called the Swedish Body Project sBody Project can decrease the emergence of eating disorders among young females. The sBody Project is based on a Dissonance-Based Intervention: DBI that has shown very promising results. The adaptations and changes in the format of delivery accomplished in this study might help to disseminate the program on a broad basis, and consequently affect the health of young females on a much larger scale the ever before.
