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

BackgroundThe 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.MethodsData was pooled from 1926 participants together with available demographic information from several research institutions.ResultsExtensive norms are presented by age and gender. Inter-correlations and regression equations based on age and gender are also presented.ConclusionsThe theoretical background and implications of work on using the O-LIFE are briefly discussed.
