Eating pathology in bulimia nervosa



Degree of eating pathology in bulimia nervosa was assessed using the Eating Behavior Rating Scale (EBRS) across three videotaped eating sessions. Twelve bulimic and 12 non-eating disordered subjects participated in this study. All subjects were filmed during a baseline meal (ad libitum), a high-calorie meal, and a low-calorie meal (both fixed amounts). Mean EBRS scores were significantly higher for bulimics (12.6 ± 1.7) than for controls (3.9 ± 0.9), suggesting a higher degree of eating pathology in these patients. Affect during eating was significantly more negative in the bulimic patients. EBRS and affect scores were significantly correlated [r (11) = .813, p < .01]. Bulimics had a slower rate of eating than controls and took significantly longer to initiate eating. Scores of pathological eating correlated with scores on the Eating Attitudes Test and the Bulimic Investigatory Test-Edinburgh, indicating a relationship between objective measures of pathological eating and self-report measures of eating disorder symptoms. © 1993 by John Wiley & Sons, Inc.
