ABSTRACT
The 15-year follow-up study (Bar, Chassin & Dionne, 2017) suggests of the Dance School Ecological Prevention Program (Piran, 1999) that it may have had long-term effects on the prevention of bulimia. This pattern of findings is in line with the results of the older cohort in the original outcome evaluation study. If the results of the follow up study hold when the 15-year outcome evaluation study is compared to a control group from a similarly competitive ballet school, this would reinforce the cause of prevention in the field of sports and dance, if not beyond. It will further support the implementation of systemic changes in the social and educational environments of children towards the prevention of eating disorders.
