Five new personality scales: their location in the factor space of personality measures.
Five scales from a picture-preference test (PPT; Auld, 1981) and a sixth, provisional scale from this test, along with some of the best established factorial tests of personality and ability, were administered to 182 university students. The marker tests included the Eysenck Personality Questionnaire, Cattell's 16 Personality Factor Questionnaire, the Hakstian-Cattell Comprehensive Ability Battery, and measures of authoritarian personality traits, obsessionality, and Machiavellianism. In order to determine the factorial composition of the five PPT scales, we computed the correlations among the 53 variables, extracted the 12 significant factors by the principal axes method, and did a direct oblimin rotation. It was shown that three of the PPT scales loaded on a single factor, which was identified as P, Eysenck's "psychoticism." We concluded that the three PPT scales may prove useful as a non-questionnaire approach to measurement of P.
