title: Evaluation of the psychometric performance of the SCOFF questionnaire in a Mexican young adult sample.
abstract: OBJECTIVE
  To examine the psychometric performance of the SCOFF, a brief screening instrument for eating disorders (ED).
  
  
  METHODS
  Mexican university applicants (n= 3594, 55.7% female, M age= 18.1 years) completed self-report measures and a health screen.
  
  
  RESULTS
  Confirmatory factor analyses revealed one factor for females. However a bifactor model fits better for males and females. Reliability was lower for females (KR20 = .49) than males (KR20 = .59). More females (24.2%) presented risk for ED (SCOFF > 2) than males (11.2%). Nomological validity indicated that risk for ED in young women was associated with demographic (e.g., parental education), psychological (e.g., depression, weight management efficacy), physical (e.g., BMI), and social (e.g., family conflict) indicators in conceptually coherent ways. Fewer variables were significant for males.
  
  
  CONCLUSIONS
  Although the SCOFF may be a useful ED screen in Mexico, further research must examine its criterion validity, sensitivity, and specificity.
