School based programs have been implemented to combat the onset of eating disorders, but most prevention programs have failed to demonstrate effectiveness (Binford & Fulkerson, 2000). For example, in a long-term, well-controlled study by Killen et al. (1993), 931 junior high school girls were randomly assigned to an intervention group or a no-treatment control group. The prevention program consisted of 18 lessons with 3 goals: understand the harmful consequences of dieting, learn to balance nutrition and exercise, and learn coping skills to combat the societal pressures to be thin. Lessons centered around the stories of 7 girls, plus writing assignments in a workbook. Participants were assessed 4 times over a 2-year follow-up. The intervention resulted in improved knowledge related to eating disorders, but there were no improvements on scores of actual disordered eating.
