Background: This study reports short scales for measuring several dimensions of schizotypy in the normal population based on a large twin sample. Methods: The four short scales use items drawn from a longer instrument, the Oxford-Liverpool Inventory of Feelings and Experiences. Using concordance estimates from MZ and DZ pairs, the items were selected both to have a high heritability and to offer broad coverage of each trait domain. Results: Preliminary descriptive statistics are reported for the short scales and suggest adequate reliability. Conclusions: New scales offer a time efficient and reliable method of studying proneness to psychosis in large N designs. (c) 2005 Elsevier B.V All rights reserved.
