As predicted there were many signi®cant correlations which add to the concurrent validity of the EPP. When the overlap of the EPP with the MBTI and LSQ is compared with the overlap of the NEO-PI with the MBTI and LSQ (derived from Furnham, 1996a,b) it appears that the EPP has greater similarity with the LSQ, but the NEO-PI has greater similarity with the MBTI. # 2001 Elsevier Science Ltd.

Introduction This study looks at the concurrent validity of the Eysenck Personality Pro®ler (EPP; Eysenck & Wilson, 1991) which measures traits at both the primary factor and super-factor level. The factor structure of the EPP has been investigated by Eysenck, Barrett, Wilson and Jackson (1992), Costa and McCrae (1995) and Jackson, Furnham, Forde and Cotter (2000). We compare the EPP with the Myers±Briggs Type Indicator (MBTI) and the Learning Styles Questionnaire (LSQ). The Jungian-based MBTI is widely used in occupational psychology and has been the subject of extensive research (Davito, 1985; Haley & Stumpf, 1989; Pittenger, 1993). Carlson (1985) notes its generally favourable validity although others disagree (Hicks, 1984; Furnham & 0191-8869/01/$ - see front matter # 2001 Elsevier Science Ltd. All rights reserved.
