Assumptions and beliefs, dieting, and predictors of eating disorder-related symptoms in young women and young men.
O'Connor M., Simmons T., Cooper M.
Differences between assumptions and beliefs related to eating disorders were investigated in young women and young men, with and without a history of dieting. The unique predictive power of these assumptions and beliefs was also assessed, compared to generic assumptions and beliefs. Both women and men with a history of dieting scored more highly than those who had never dieted on assumptions related to weight, shape, and eating, but did not differ from this group in negative self-beliefs. Assumptions and beliefs related to eating disorders, as well as female gender, but not body mass index (BMI), history of dieting, or generic assumptions and beliefs, predicted eating disorder-related symptoms. The findings add to knowledge about the relationship between assumptions and beliefs, gender, dieting, and eating disorder-related symptoms. They also support the usefulness of the Eating Disorder Belief Questionnaire (EDBQ), a new measure of eating disorder-specific assumptions and beliefs.
