Psychometric appraisal of Eysenckʹs revised Psychoticism scale: a cross-cultural study

Psychometric characteristics of Eysenckʹs revised P scale were studied in a cross-cultural research. The Spanish version of the Eysenck Personality Questionnaire-Revised (EPQ-R) was administered to a Spanish sample of 527 males and 583 females. Maximum-likelihood factor analyses of the item intercorrelations and Direct Oblimin rotations of the extracted factors were carried out separately for males and females. The results revealed four factors identified as psychoticism (P), extraversion (E), neuroticism (N) and dissimulation/conformity (L). Internal consistency and test–retest reliability coefficients were satisfactory and very similar to the ones found in the original study. Skewness and kurtosis of the P scale distribution were closer to normal than on the original British revised P scale.
