Formatted Abstract/Summary
Background:
Individuals with schizophrenia have more minor physical anomalies ŽMPAs. and altered craniofacial measurements compared to well controls. However, closer examination of the range of beliefs and experiences in well controls suggests that there is a continuum of sub-syndromal quasi-psychotic experiences in well controls. In this study we hypothesised that well individuals who had more MPAs and craniofacial features typical of schizophrenia would score higher on instruments designed to assess quasi-psychotic phenomena.

Methods:
Craniofacial MPAs and quantitative measures related to head size, facial heights and depths were examined in 303 well controls screened to exclude psychotic disorders. Several instruments were used to examine the presence of quasi-delusional beliefs ŽPeter Delusional Inventory, Paranormal Belief Inventory., quasi-hallucinatory experiences ŽPerceptual Aberration Scale. psychosis- proneness Žselected Chapman and Chapman items., and disorganized communication ŽCommunication Awareness Scale..

Results:

There was a significant correlation between Ža. higher total MPA scores and Žb. higher scores on the Paranormal Belief Inventory Ž ps0.03. and on the Psychosis Proneness items Ž ps 0.02.. Paradoxically, those with higher scores on the Psychosis Proneness items had craniofacial features characterized by smaller skull bases and longer lower facial heights Ž ps0.02., features opposite to that associated with schizophrenia.

Discussion:

The genetic andror environmental factors that account for the association between MPAs and psychosis may also influence the presence of quasi-psychotic phenomena in well individuals. However, the association between these phenomena and craniofacial measures requires further clarification. The Stanley Foundation supported this project.
