The study investigated body figure preferences, eating disorder symptomology, and role concerns in 142 Australian caucasian adolescent girls in two different school environments, both of medium to high socioeconomic status. Girls at a private single-sex school nominated a thinner ideal figure and displayed more eating disorder patterns than their counterparts at a private coeducational school. Although the schools did not differ in role concerns, these had a differential impact on prediction of the ideal figure. In particular, the importance placed on professional success predicted the choice of ideal figure for the single-sex but not for the coeducational school. It was concluded that what motivates the wish for thinness differed between the schools.
