NEW SCALES FOR THE ASSESSMENT OF SCHIZOTYPY

This study reports the development of new scales for assessing schizot ypal traits. The four scales measure unusual experiences, cognitive di sorganisation, introvertive anhedonia and impulsive non-conformity. Th e scales were incorporated into a new questionnaire, the Oxford-Liverp ool Inventory of Feelings & Experiences (O-LIFE), in a form designed f or use in the normal population and including filler items as well as the STA scale (as a known referent). Norms for the scales on a fresh s ample of normal subjects (N = 508) are reported, including sex and age differences. All the scales were found to have adequate internal cons istency (coeff. alpha > 0.77). The items from the four new scales were submitted to factor analysis and a highly similar structure resulted. Their present and future use in psychosis-proneness research is discu ssed.
