The DSM-5 effect: psychological characteristics of new patients affected by Binge Eating Disorder following the criteria of the DSM-5 in a sample of severe obese patients.

PURPOSE: The current study evaluated whether or not there were significant differences in psychopathological traits between three groups of individuals. The first was a group of patients seeking bariatric surgery diagnosed as being affected by Binge Eating Disorder (BED), according to the new criteria of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. This group (NEW BED group) did not meet BED diagnosis following the previous criteria listed in the DSM-IV-TR. The second group of individuals was composed of severely obese patients seeking bariatric surgery not affected by an eating disorder, according to the diagnostic criteria of the DSM-5 (OB group). The third group was composed of individuals within a healthy weight range (Control group).

METHODS: 94 severely obese patients (33 in the NEW BED group and 61 in the OB group) were compared to the Control group including 41 participants on depression, anxiety and eating habits.

RESULTS: The NEW BED scored significantly higher than the OB group on the Beck Depression Inventory, both the subscales of the State Trait Anxiety Inventory, on disinhibition and hunger subscales of the Three-Factor Eating Questionnaire and on many subscales of the Eating Disorders Inventory.

CONCLUSIONS: The new, less restrictive diagnostic criteria for BED of the DSM-5 are useful in identifying obese patients affected by severe psychopathology and dysfunctional eating habits.
