title: [Clinical characteristics and gender identity among eating disordered patients subtypes].
abstract: BACKGROUND
  Gender identity is a relevant issue in the approach to eating disorders.
  
  
  OBJECTIVE
  To compare psychological and behavioural characteristics and traits of gender identity among women with eating disorders and its subtypes and non eating disordered female subjects.
  
  
  METHODS
  An structured clinical interview based on the DSM-IV diagnostic criteria for eating disorders, the EAT-40 (Eating Attitudes Test), the Eating Disorders Inventory (EDI) and the Bem Sex Role Inventory (IBRS) were administered to 58 compulsive-purgative anorectics (AN/BN group), 15 restrictive anorectics (AN group), 33 patients suffering from eating disorder not otherwise identified, 33 purgative bulimics and to 82 female students without eating disorders.
  
  
  RESULTS
  Patients with eating disorders ranked significantly higher on the EAT-40 and EDI and all its items (p < 0.001). The AN/BN group ranked significantly higher on the EDI (p < 0.001) and on Drive for thinness, Perfectionism and interpersonal distrust (p < 0.001). The AN group ranked higher on Maturity fears (p < 0.001). The BN group ranged higher on Body dissatisfaction, Ineffectiveness and Interoceptive awareness (p < 0.001). Patients with eating disorders were significantly identified with Feminine category and subjects without eating disorders with Androgynous and Undifferentiated categories on the IBRS (p = 0.002). The AN group showed the highest percentage on Feminine category and the lowest on Androgynous and Undifferentiated categories. All the groups rejected and approved feminine, masculine and neutral qualities.
  
  
  CONCLUSIONS
  Femininity emerged as the main trait of gender identity in patients suffering from eating disorders, in contrast to androgyny, showed by healthy women.
