In this paper, we describe the DSM-5 approach to the diagnosis and
description of schizophrenia and discuss the rationale for changes made
from DSM-IV. As with other disorders in DSM-5 (Regier et al., 2009), a
conservative approach towards revisions was utilized. Changes were
made only if they substantially improved clinical utility or enhanced
validity and increased concordancewith the International Classification
of Diseases (ICD,World Health Organization, 1992; Gaebel et al., 2013)
definition of schizophrenia.
