Self-centrality, basic symptoms model and psychopathology in schizophrenia.

The study's aim was to empirically derive the psychopathological constellation associated with self-centrality (i.e. non-delusional self-referential attitude) by seeking an interpretation in the light of the 'Basic Symptoms Model' of schizophrenic psychopathology. Eighty-four patients with an established schizophrenic illness receiving maintenance treatment at the Psychiatry Section of the Parma University Neuroscience Department were examined. The Scales for the Assessment of Positive and Negative Symptoms, the Calgary Depression Scale and the Toronto Alexithymia Scale were administered to all subjects to determine levels of positive, disorganized, negative and depressive symptoms, as well as alexithymia. Subjective experiences, including non-delusional self-centrality, were explored by means of the Bonn Scale for the Assessment of Basic Symptoms. Logistic regression detected three different psychopathological domains (delusional, alexithymic, and basic body symptoms) strongly associated with self-centrality. Among these the most influential independent variable was basic body symptoms. These results suggest that impaired lived body experience (i.e. protopathic body disattunement) is a psychopathologic condition concomitant with the emergence of autocentric polarization of experience (i.e. self-centrality).
