rion A.
C. The disturbance is not better explained by a psychotic disorder that is not substance/
medication-induced. Such evidence of an independent psychotic disorder could in-
clude the following: 
The symptoms preceded the onset of the substance/medication use; the symptoms
persist for a substantial period of time (e.g., about 1 month) after the cessation of
acute withdrawal or severe intoxication; or there is other evidence of an indepen-
dent non-substance/medication-induced psychotic disorder (e.g., a history of recur-
rent non-substance/medication-related episodes).
D. The disturbance does not occur exclusively during the course of a delirium.
E. The disturbance causes clinically significant distress or impairment in social, occupa-
tional, or other important areas of functioning.
Note: This diagnosis should be made instead of a diagnosis of substance intoxication or
substance withdrawal only when the symptoms in Criterion A predominate in the clinical
picture and when they are sufficiently severe to warrant clinical attention.
