The authors review the important changes in the three sections of DSM-
III-R that include only psychotic disorders (schizophrenia, delusional
disorder, and psychotic disorders not elsewhere classified), outline the
rationale for these changes, and, where available, review their empirical
basis. In addition, they review two proposed changes that were not
incorporated into DSM-III-R. They conclude by calling for an increasingly
rigorous and data-based process of nosologic revision.Abstract Teaser
