The nature of schizotypy.

The matrix of intercorrelations between scales of schizotypy presented by Kendler and Hewitt in 1992 was reanalyzed, and results rather different from those reported by the original authors were found. The new structure shows good agreement with the theory of personality disorder published by Eysenck in 1987. In all, the different scales seem to fall into three groups or factors, identified as Neuroticism (N), Extraversion (E), and Psychoticism (P). It is doubtful if there is a common element left over once these three groups have been eliminated.
