| Abstract: | Established 3 criteria by which the concepts of schizophrenia in Diagnostic and Statistical Manual of Mental Disorders, 2nd edition (DSM-II) could be analyzed: reliability, coverage, and overlap. 71 artificial patients were generated to uniformly represent a behavioral measurement space. 55 clinical psychologists and psychiatrists diagnosed the artificial patients using the DSM-II classificatory concepts of schizophrenia. Results concerning the criteria show that: (a) an empirical representation of overlap provided a new hierarchical representation of the DSM-II classification of schizophrenia; (b) reliability and coverage varied inversely; and (c) the DSM-II failed to serve as an adequate nomenclature.
