A prospective study of disordered eating among sorority and nonsorority women

The current study examined disordered eating prospectively among sorority and nonsorority women.

University women were surveyed during their first, second, and third undergraduate years. Disordered eating, depression, self-esteem, body mass index (BMI), and ideal weight were measured.

Disordered eating did not differ between the groups before women joined sororities. By Time 3, sorority women reported higher Eating Disorder Inventory (EDI) Drive for Thinness subscale scores than nonsorority women, but the EDI Bulimia and Body Dissatisfaction subscales did not differ. BMI, ideal weights, depression, and self-esteem did not differ.

Women who join sororities are similar to those who do not in their baseline levels of disordered eating, but they maintain more rigorous attitudes and behaviors regarding dieting over the course of their higher education.
