title: Is decision making really impaired in eating disorders?
abstract: OBJECTIVE
  Decision making has been reported to be reduced in eating disorders. However, studies are sparse and have been carried out in various selected populations. In the current study we arranged to confirm previous observations and to assess the relationship between decision making and dimensions relevant to eating disorders.
  
  
  METHODS
  Patients suffering from anorexia nervosa (n = 49), bulimia nervosa (n = 38), and healthy controls (n = 83) were assessed using the Iowa Gambling Task (IGT). All patients were euthymic and free of psychotropic medication. Self-questionnaires (Eating Disorder Inventory-2; Gardner, 1991; and Eating Attitude Test; Garner & Garfinkel, 1979) were used to assess clinical dimensions relevant to eating disorders.
  
  
  RESULTS
  No significant differences in IGT performance were observed between patients and healthy controls or between restrictive and purging types of anorexia nervosa. No correlations were found between IGT performance and eating disorder questionnaires.
  
  
  CONCLUSIONS
  These results do not support reduced decision making in patients with eating disorders, and suggest that previously reported alterations could be related to other clinical characteristics. This should stimulate new topic-related studies designed to reach a firm conclusion.
