The Revised Junior Eysenck Personality Questionnaire (JEPQ-R): Dutch replications of the full-length, short, and abbreviated forms

This study examines the full-length, short and abbreviated forms of the Revised Junior Eysenck Personality Questionnaire (JEPQ-R) in a Dutch sample of 215 boys and 207 girls, aged 12–14. The reliability and concurrent validity of the scales of the full-length form (JEPQ-R, 81 items), short form (JEPQR-S, 48 items) and abbreviated form (JEPQR-A, 24 items) are satisfactory. Results indicate that the short and abbreviated forms can be recommended as functional equivalents to the 89-item full-length JEPQ-R when the research context does not permit the application of the longer instrument. The need for further examination and development of the short and abbreviated Psychoticism scale is emphasized and other recommendations for future research are given.
