| Popis: | This study contrasted the amount of food eaten in the absence of vomiting by normal weight bulimia nervosa patients and matched normal controls. Another purpose was to compare food consumption in test meals with eating records at home and with questionnaires of psychological distress and eating disturbance. Subjects were instructed to eat as much food as they comfortably could without vomiting afterwards in three standardized test meals: complete dinner eaten in a laboratory situation and spaghetti and candy eaten at home. Bulimia nervosa subjects ate a very small amount of food in each test meal when compared with the consumption of food by control subjects. Bulimia nervosa subjects also reported greater anxiety and urge to vomit after eating. A content analysis of tape recorded thoughts showed that bulimia nervosa subjects were more preoccupied with eating and emitted more negative food related thoughts. In addition, bulimia nervosa patients who ate little or nothing in test meals had a more severe pattern of binge-eating and vomiting at home and for the entire sample, the amount eaten in test meals, when vomiting was prevented, was negatively correlated with scores on questionnaires of eating and psychological disturbance. The results support the hypothesis that women with bulimia nervosa are unable to eat normal amounts of ‘frightening’ foods when they do not plan to vomit. This behavioral test of eating behavior appears to be useful for the assessment of bulimia nervosa. |
