The Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE): Further description and extended norms

Abstract

Background: The Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE) was introduced in 1995 as a four-scale questionnaire for measuring psychosis-proneness, principally schizotypy. Its items were deliberately chosen to make it suitable for tapping psychotic characteristics in healthy individuals. Since its inception the O-LIFE has been used in a wide variety of experimental and clinical studies, establishing its reliability and validity. Methods: Data was pooled from 1926 participants together with available demographic information from several research institutions. Results: Extensive norms are presented by age and gender. Inter-correlations and regression equations based on age and gender are also presented. Conclusions: The theoretical background and implications of work on using the O-LIFE are briefly discussed. © 2005 Elsevier B.V. All rights reserved.
