The development of an abbreviated form of the revised Junior Eysenck Personality Questionnaire (JEPQR-A) among 13–15 year olds

An abbreviated form of the Junior Eysenck Personality Questionnaire (JEPQR), consisting of four scales of six items each, is developed from the short-form JEPQR. The internal reliability and concurrent validity of the scales of this abbreviated questionnaire are established among 1597 13–15-year-olds in Wales. The 24-item abbreviated JEPQR (JEPQR-A) is recommended as a good functional equivalent to the 48-item short-form JEPQR (JEPQR-S) in situations where it may be inappropriate to employ the longer instrument.
