Bulimia nervosa and dietary restraint

Patients with bulimia nervosa were compared with non-bulimic restrained and unrestrained eaters on several questionnaire and interview measures related to eating patterns, preoccupation with dieting and food, and general psychopathology. Bulimic subjects did not differ significantly from non-bulimic restrained eaters on measures of fear of weight gain, dietary restraint, and the Eating Disorders Inventory (EDI) subscales of Drive for Thinness and Body Dissatisfaction, although both groups scored significantly higher on these measures than unrestrained eaters. Subjects with bulimia nervosa differed significantly from both restrained and unrestrained eaters on the Eating Habits Checklist, the Beck Depression Inventory, the EDI total score and Interoceptive Awareness, Introversion and Bulimia subscales, the Three Factor Eating Questionnaire (TFEQ), Disinhibition subscale and the Symptom Checklist 90-revised version. These findings show that bulimic patients may be quite similar to their restrained, non-bulimic counterparts on dietary concern and ideals of slenderness and suggest the importance of including a restrained control group in attempts to isolate the variables that differentiate individuals with the clinical eating disorder from their peers who demonstrate normative discontent about body weight and shape.
