How does the cognitive approach explain bulimia?
According to the cognitive view of bulimia nervosa, these extreme concerns, described by Russell as “a morbid fear of becoming fat” and the American Psychiatric Association as the “persistent overconcern with body shape and weight”, are a central feature of the psychopathology of the disorder.
