EPQ-R examines basic personality dimensions according to Eysenck’s theory.
EPQ-R in the standard version contains 106 questions to be answered with Yes or No. Results are presented in 6 scales. Three of them – Psychoticism (P), Extraversion (E), Neuroticism (N) concern the main personality traits. Control scale – Lie (L) assesses the tendency to present oneself in a favorable way. Two additional scales – Addiction scale (A) and Criminality scale (C) help to identify persons with some disorders.
EPQ-R short version contains 48 items from the full EPQ-R. Results are presented in four scales: Psychoticism (P), Extraversion (E), Neuroticism (N), and Lie (L).

EPQ-R(S): Satisfactory stability of scores in all the scales, satisfactory internal consistency of Extraversion, Neuroticism, and Lie, low of Psychoticism.
Validity
EPQ-R: confirmed factor validity, correlations with other personality measures (MMPI-2, ACL, STAI) and Rokeach Value Survey. Criterion validity assessed by analyzing clinical groups’ results (neurotics, alcoholics, drug addicts, prisoners) plus results of job groups and unemployed people.
EPQ-R(S): Confirmed factor validity, correlations with other personality measures – MMPI-2, ACL, STAI and IVE Impulsiveness Questionnaire.
