Continuing our occasional series of free practice questions based upon the DSM. Here's one that comes from the Feeding and Eating Disorders chapter. There are eight diagnoses included in the chapter (including Unspecified Feeding or Eating Disorder). How many of the other seven can you name? They're listed below, after the question. First, here the practice question:
A woman seeks help from a social worker for an eating disorder. She reports regularly eating large amounts of breakfast cereal right before bedtime, leaving her feeling uncomfortable and miserable. She often takes laxatives in order to flush out the unwanted food. What is the MOST likely diagnosis for this client?
A) Bulimia Nervosa
B) Binge-Eating Disorder
C) Night Eating Syndrome
D) Anorexia Nervosa Binge/Purging Type
What do you say?
In the DSM-5, binge-eating disorder has leapt from "for further study" to a full-fledged diagnosis. What is described here, however, is not binge-eating disorder. The woman's laxative use is what's called a "compensatory behavior" in the DSM-5 (like purging, fasting, or exercising excessively). In binge-eating disorder, there are no compensatory behaviors. Night eating syndrome is diagnosed when criteria for the other Feeding or Eating Disorders aren't met. Anorexia nervosa no longer includes a binge/purging type as it did in DSM-IV-TR. The best answer here is A) bulimia nervosa.
Here are those eight diagnoses from the Feeding and Eating Disorders chapter of DSM-5:
- Pica (eating nonnutritive food, e.g., dirt)
- Rumination Disorder (regurgitation of food)
- Avoidant/Restrictive Food Intake Disorder (what it sounds like--avoiding and restricting food intake)
- Anorexia Nervosa (restrictive energy intake that leads to low body weight)
- Bulimia Nervosa (recurrent binge eating with compensatory behaviors, e.g., self-induced vomiting)
- Binge-Eating Disorder (recurrent binge eating without compensatory behaviors)
- Other Specified Feeding or Eating Disorder (e.g., purging disorder (purging without binge eating); night eating syndrome)
- Unspecified Feeding or Eating Disorder (symptoms cause distress but don't meet full criteria of any of the above)
