What Is the EPQ-RS?
The Eysenck Personality Questionnaire Revised Short (EPQ-RS) measures three core dimensions of personality: Extraversion, Neuroticism, and Psychoticism -- plus a Lie scale to catch socially desirable responding.
Eysenck believed these three dimensions had biological roots. Extraversion links to cortical arousal, Neuroticism to the limbic system, and Psychoticism to testosterone and serotonin levels.
