As Cited in the Textbook, One Reason to Use Categories

As cited in the textbook, one reason to use categories in diagnosing psychopathology is that they:

A) aid in identification of possible treatments
B) allow psychologists to see if the person has a mild or an extreme form of the disorder
C) reflect the way the disorder actually works-either a person has the disorder or does not have it
D) create a highly unique case study of the person's illness
