We present an overview of self-report scales for measuring schizotypy
and a review of factor-analytical studies of these scales. These studi
es show that schizotypy is a multidimensional construct consisting of
three or four factors. Positive Schizotypy, Negative Schizotypy, Nonco
nformity, and possibly Social Anxiety/Cognitive Disorganization. Clini
cal and external validation studies provide support for the construct
validity of the Positive Schizotypy and Negative Schizotypy factors, b
ut as yet fail to support the Nonconformity and Social Anxiety/Cogniti
ve Disorganization factors. In accordance with this multidimensional s
tructure, the stales for measuring schizotypy can be classified as fac
tor-specific scales. We consider the striking similarities between the
multidimensionality of schizotypal traits and the multidimensionality
of schizophrenic symptoms. We also look at the similarities and diffe
rences between schizotypy and normal personality traits. Some practica
l and theoretical implications of these relationships are discussed.
