The aim of this study was to evaluate the effectiveness of a school-based e
ating disorder prevention program designed to reduce dietary restraint and
concern about shape and weight among adolescent girls. Method: A total of 4
74 girls aged 13-14 years received the program as part of their normal scho
ol curriculum. An assessment-only control group included 386 pupils. Measur
es of eating disorder features, self-esteem, and knowledge were administere
d before and after the intervention and at 6-month follow-up. Results: Imme
diately following the intervention, there was a small reduction in dietary
restraint and attitudes to shape and weight in the index group, whereas the
re was no change in the control group. This reduction was not maintained at
6-month follow-up although the dietary restraint scores of the index group
remained lower than those of the control group. Discussion: This preventio
n program achieved change in eating attitudes and behavior, although the ch
ange was modest in size and not sustained. Focusing on a high-risk subgroup
of dieters might be a more fruitful primary prevention strategy. (C) 2001
