BACKGROUND: Contemporary psychopathological research has shown that some qualitative anomalies of the first-person experiential givenness qualify the subjective experience of schizophrenia. Such essential clinical features of schizophrenia have recently been condensed into 7 phenomenologically coherent clusters derived from the Bonn Scale for the Assessment of Basic Symptoms (BSABS). The experimental intent of this study was to test whether subapophanic self-centrality (i.e. a protopathic nondelusional form of intersubjective spatial disattunement) empowers the discriminant capacity of such a set of subjective experiential disturbances among different diagnostic groups. METHOD: Three comparably sized samples of outpatients with schizophrenia, obsessive-compulsive or mood disorders were examined with the BSABS. Logistic regression analysis was performed with diagnosis as the outcome variable. RESULTS: Elevated scores in self-perceived cognitive disorders and abnormal self-centrality were associated with DSM-IV diagnosis of schizophrenia. Self-centrality increased the discriminant capacity of the 7 designed a priori dimensions. CONCLUSIONS: These findings confirm the previously reported aggregation of some subtle qualitative alterations of subjective experience in schizophrenia, and suggest that a careful consideration of autocentric disturbances of intersubjectivity might enrich current heuristics on schizophrenic experiential vulnerability.
