Abstract: 

Aim The aim of the study was to explore correlations between self-disorders (SDs), other measures of psychopathology (perceptual disturbances, formal thought disorders, and positive and negative symptoms), IQ, and extrinsic illness characteristics in a sample of young first admission patients. Method A sample of 100 diagnostically heterogeneous, first-admitted in-patients underwent comprehensive psychiatric interviews. SDs were assessed by means of the EASE scale. An experienced psychiatrist conducted all the interviews and patients were diagnosed according to DSM-IV. All interviewed subjects were IQ-tested. Correlations were tested with Spearmans correlations coefficient. Results SDs aggregated significantly within the schizophrenia spectrum disorders. Moreover, significant positive correlations between SDs, positive and negative syndromes, formal thought disorders and disturbances of perception. We found no correlation between the SDs and DUP, DUI or IQ. Conclusion and implications The results document that SDs aggregate significantly in schizophrenia spectrum disorders but not in other mental illnesses, a finding consistent with previous studies. The correlations with the well-known schizophrenia symptoms correoborate the notion that SDs constitute fundamental features of schizophrenia spectrum psychopathology. This has great implications for early intervention and early differential diagnosis. We suggest to include screening for SDs in standard assessment of psychiatric patients as it may enable more accurate and earlier identification of at-risk mental states tagged with a propensity to unfold into manifest schizophrenia or schizotypal disorder. The lack of correlations between SDs and DUP or DUI may indicate that SDs form more basic vulnerability traits. Our results also suggest that the SDs are not IQ depended.
