The Eysenck Personality Questionnaire-Revised (EPQ-R) measures three major dimensions of personality that account for most of the variance in personality. The EPQ-R is an excellent choice when you are administering a test battery and need a brief instrument representing the personality domain. This measure has proven useful for numerous applications in human resources, career counseling, clinical settings and research. Scales measured by the EPQ-R are Extraversion-Introversion, Neuroticism and Toughmindedness with the addition of a Lie Scale. The long form of the EPQ-R was developed in 1993, the short form in 2001.(PsycTests Database Record (c) 2022 APA, all rights reserved)
