ABSTRACT The objective of the present paper was to validate a French version of the Eysenck Personality Questionnaire-Junior (EPQ-J), which, in accordance with the corresponding questionnaire for adults, was postulated to have a four-factor structure including Neuroticism, Extraversion, Psychoticism and a Lie Scale. We tested the factor structure and internal reliability of the French translation in a sample of 465 school children (mean age: 12 years) recruited from the general population. Confirmatory factor analysis revealed the original orthogonal four-factor structure to have an unsatisfactory fit. However, by removing the constraint of orthogonality, a satisfactory fit could be achieved. Internal reliability estimates were 0.84 for Neuroticism, 0.74 for both Extraversion and the Lie scale and 0.69 for Psychoticism. These results based on a sample of young adolescents provide evidence for the validity of the French translation and further support for the stability of the four major personality dimensions across the lifespan.

    ABSTRACT: Construct validation was introduced in order to specify types of research required in developing tests for which the conventional views on validation are inappropriate. Personality tests, and some tests of ability, are interpreted in terms of attributes for which there is no adequate criterion. This paper indicates what sorts of evidence can substantiate such an interpretation, and how such evidence is to be interpreted." 60 references.

    ABSTRACT: The adult version of the Psychoticism scale has recently been revised in an attempt to rectify three major psychometric deficiencies. An inspection of the EPQ manual indicates that these faults can also be found in the junior version. In an attempt to improve the junior scale, 1325 school children (491 male and 834 female) completed a revised version of the junior EPQ. The reliability and range of scoring on the revised P scale is now higher than on the original scale. Results of item factor analyses are reported and a revised short form of the junior EPQ is also presented.
