SYNOPSIS A study is reported of a random sample of 170 normal men and 192 normal women who were given a 110-item questionnaire incorporating items intended to measure personality variables P (psychoticism), N (neuroticism), E (extraversion), and L (a lie and dissimulation scale). Factor analysis of the intercorrelations between items disclosed a clear-cut psychoticism factor, relatively independent of the others. The rationale and the psychiatric importance of this factor are discussed.
