title: [Lack of assertiveness in patients with eating disorders].
abstract: BACKGROUND
  Low self-assertion has been noted as an important feature among patients with eating disorders.
  
  
  OBJECTIVE
  To verify, in a female population, if assertiveness is related or has a predictive capacity for the development of eating disorders.
  
  
  METHODS
  An structured clinical interview, the Eating Attitudes Test (EAT-40) and the Rathus Assertiveness Scale (RAS) were administered to 62 patients that fulfilled the DSM-IV diagnostic criteria for eating disorders and to 120 female students without eating problems.
  
  
  RESULTS
  Patients with eating disorders ranked significantly higher on the EAT-40 and its factors (p <0.001) and showed a lower level of assertiveness on the RAS (p <0.001). Assertiveness measured by RAS and its factors was inversely related to EAT-40 and its items (r= -0.21). The predictive capability of the lack of self-assertion in the development of an eating disorder reached 53%, when patients with eating disorders and subjects at risk were considered together and compared to students without such disorder.
  
  
  CONCLUSIONS
  Lack of assertiveness is a significant trait in patients with eating disorders; it may worsen its outcome and even perpetuate symptoms. Low self-assertion may be considered a predictive factor in the development of an eating disorder and must be managed from a preventive or therapeutic point of view.
