Validation of the French version of the EPQ-Junior
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: This study aimed to investigate the validity of the Eysenckian personality dimensions in 1,368 children and adolescents who completed the Greek Eysenck Personality Questionnaire-Junior (EPQ-J). Exploratory and confirmatory factor analyses were employed. Controversial issues regarding the Lie and Psychoticism scales were also investigated. Finally, the predictive validity of the EPQ-J was assessed using Goodman’s Strengths and Difficulties Questionnaire. Confirmatory factor analytic results supported the four-factor structure of the scale. Results provide support for the appropriateness of the EPQ-J with Greek speaking samples and add to the international literature regarding the three-factor model of personality in children and adolescents.

- "For the measurement of personality traits in children the junior version of the EPQ (EPQ-J: Eysenck and Eysenck, 1975) was applied, which is comprised of 81 items. Our group has previously established and validated its French translation (Rothen et al., 2008). Validation was based on confirmatory factor analysis, which revealed a sufficient fit of an oblique factor solution testing the three original EPQ dimensions as well as the Lie scale. "

ABSTRACT: Using family study data, the following questions regarding the mechanisms of association between personality traits and mood disorders were addressed: 1) Is there an association between unipolar and bipolar mood disorders and personality traits in probands? 2) Are personality traits associated with depression in their 9 to 17 year-old children? 3) Is there an association between parental mood disorders and personality traits in offspring? 4) Are parental personality traits associated with the risk of depression in offspring?
The study included 50 probands with bipolar and 37 with unipolar mood disorder, 34 healthy controls as well as 178 of their children between 9 and 17 years. Diagnoses were made according to a best-estimate procedure based on a semi-structured interview (DIGS), medical records and family history information. Personality traits were assessed using the Eysenck Personality Questionnaire in adults and the Eysenck Personality Questionnaire Junior in offspring.
Personality traits, and in particular Neuroticism, were found to be associated with mood disorders in currently affected as well as remitted probands and offspring. However, there was no association between mood disorders in parents and personality traits in their children, and conversely, parental personality traits were not associated with the risk of depression in offspring.
1) Relatively small proportion of offspring who were still unaffected but likely to subsequently develop mood disorders; 2) cross-sectional design.
The findings were best compatible with the complication or scar hypothesis, which assumes the occurrence of abnormal personality traits as a consequence of previous depressive episodes.
