Abstract

Two hundred and fifty-five psychiatric inpatients with a definite diagnosis of DSM-IV schizophrenic disorder were examined by means of the Structured Clinical Interview and rated on the 30 main items of the Positive and Negative Syndrome Scale (PANSS). Patients’ scores were subjected to a cluster analysis, using Ward’s method. Cluster analysis indicated the existence of five groups. The first group (n = 46) comprised patients with overall psychopathology of minimal severity, the second group (n = 39) patients with severe positive symptoms along with symptoms of psychomotor excitement, the third group (n = 58) patients with severe positive psychopathology only, the fourth group (n = 34) patients with severe positive negative depressive and cognitive symptoms and, finally, the fifth group (n = 78) patients with severe negative symptoms only. Patients in the first and third groups were older and their illnesses were of longer duration compared to those of the remaining groups. With respect to DSM-IV clinical types of schizophrenic disorders, the paranoid type predominated in the second and the third groups, whereas the disorganized and catatonic types were markedly overpresented in the fifth group.
