comparable to those produced by the substa nce use disorders. Other excessive behavioral
patterns, such as Internet gaming, have also been described, but the research on these and
other behavioral syndromes is less clear. Thus, groups of repetitive behaviors, which some
term behavioral addictions,  with such subcategories as “sex addiction,” “exercise addiction,”
or “shopping addiction,” are not included becaus e at this time there is insufficient peer-re-
viewed evidence to establish the diagnostic criteria and co urse descriptions needed to
identify these behaviors as mental disorders. 
The substance-related disorder s are divided into two groups: substance use disorders
and substance-induced disorders. The followi ng conditions may be classified as sub-
stance-induced: intoxication, withdrawal, an d other substance/medication-induced men-
tal disorders (psychotic disord ers, bipolar and related disorders, depressive disorders,
anxiety disorders, obsessive-compulsive and re lated disorders, sleep disorders, sexual dys-
functions, delirium, and neurocognitive disorders). 
The current section begins with a general di scussion of criteria sets for a substance
use disorder, substance intoxication and withdrawal, and other substance/medication-
induced mental disorders, at  least some of which are a pplicable across classes of sub-
stances. Reflecting some unique  aspects of the 10 substance classes relevant to this chapter,
the remainder of the chapter is  organized by the class of substance and describes their
unique aspects. To facilitate differential diagnosis, the text and criteria for the remaining
substance/medication-induced mental disorder s are included with disorders with which
they share phenomenology (e.g ., substance/medication-induced depressive disorder is in
the chapter “Depressive Disorder s”). The broad diagnostic cate gories associated with each
specific group of substances are shown in Table 1.
