title: [Validation of the Eating Attitudes Test as a screening instrument for eating disorders in general population].
abstract: OBJECTIVE
  To validate the best cut-off point of the Eating Attitudes Test (EAT-40), Spanish version, for the screening of eating disorders (ED) in the general population.
  
  
  METHODS
  This was a transversal cross-sectional study. The EAT-40 Spanish version was administered to a representative sample of 1.543 students, age range 12 to 21 years, in the Region of Madrid. Six hundred and two participants (probable cases and a random sample of controls) were interviewed.
  
  
  RESULTS
  The best diagnostic prediction was obtained with a cut-off point of 21, with sensitivity: 88.2%; specificity: 62.1%; positive predictive value: 17.7%; negative predictive value: 62.1%.
  
  
  CONCLUSIONS
  Use of a cut-off point of 21 is recommended in epidemiological studies of eating disorders in the Spanish general population.
