The SCOFF questions*:

  1. Do you make yourself Sick because you feel uncomfortably full?
  2. Do you worry you have lost Control over how much you eat?
  3. Have you recently lost more than One stone in a 3 month period?
  4. Do you believe yourself to be Fat when others say you are too thin?
  5. Would you say that Food dominates your life?
*One point for every "yes"; a score of 2 indicates a likely case of anorexia nervosa or bulimia

 

Setting the threshold at two or more positive answers to all five questions provided 100% sensitivity for anorexia and bulimia, separately and combined (all cases, 95% confidence interval 96.9% to 100%; bulimic cases, 92.6% to 100%; anorectic cases, 94.7% to 100%), with specificity of 87.5% (79.2% to 93.4%) for controls The false positive rate of 12.5% is an acceptable trade off for very high sensitivity.
