the exclusionary criterion for conduct diso rder has been removed. The criteria for conduct

more specific criteria defining  frequency needed to meet the criteria and specifies that the
aggressive outbursts ar e impulsive and/or anger based in nature, and must cause marked
distress, cause impairment in occupational or interpersonal functioning, or be associated
with negative financial or legal consequences. Furthermore, a minimum age of 6 years (or
equivalent developmental level) is now required.

An important departure from past diagnostic ma nuals is that the chapter on substance-related
disorders has been expanded to include gambling disorder. Another key change is that

where relevant. Within substance use disorders,  the DSM-IV recurrent substance-related legal
problems criterion has been dele ted from DSM-5, and a new criter ion—craving, or a strong de-
sire or urge to use a substance—has been adde d. In addition, the thre shold for substance use
disorder diagnosis in DSM-5 is set at two or more  criteria, in contrast to a threshold of one or
