title: Short scales for measuring schizotypy.
abstract: 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.
