Differences in the prevalence of psychosensory features among schizophrenic, schizoaffective, and manic patients.
The purpose of the study was to test the sensitization model for mood disorder by comparing the prevalence of psychosensory features in bipolar, schizoaffective-manic, and schizophrenic patients. We evaluated 66 patients (13 schizophrenics, 13 schizoaffective bipolar types, and 40 bipolars) for the presence of psychosensory features and psychopathology. Schizoaffective manics had the highest prevalence of recent (F = 6.9(2,32), P = < .001) and past (F = 3.7(2,32), P = < .05) psychosensory features. We conclude that psychosensory features are markers of severity of affective rather than nonaffective psychosis.
