Purpose

The purpose of the questionnaire is to assess the personality of children and adolescents, based on Eysenck’s theory of the three major dimensions of personality. This tool aims to provide a brief but reliable evaluation of key personality traits.

Brief Description

The questionnaire consists of 24 items and is derived from the Revised Abbreviated Form of the Eysenck Personality Questionnaire. It represents a shortened version of the original 48-item questionnaire and is designed to measure three primary personality dimensions: neuroticism, extraversion, and psychoticism. Additionally, it includes a lie scale to help evaluate the honesty of the respondents’ answers.

Sample

The instrument was standardized on a sample of 551 elementary school students, of whom 269 were girls and 282 were boys. Participants were in the last three grades of primary school and ranged in age from 9 to 12 years old.

Scoring Method

Each item is scored based on the participant’s response. Specifically, a “yes” response is scored as 1 and a “no” response is scored as 0. In cases where reverse scoring is applied, a “no” is scored as 1 and a “yes” as 0.

Validity

The validity of the tool has been examined through the correlation between the neuroticism scale of the JEPQR-A and that of the JEPI, yielding a correlation coefficient of 0.49. This indicates a satisfactory level of convergent validity.

Reliability

Internal consistency reliability (Cronbach’s alpha) for the individual scales is moderate: 0.27 for extraversion, 0.60 for neuroticism, 0.42 for psychoticism, and 0.50 for the lie scale. Test-retest reliability coefficients are as follows: 0.42 for extraversion, 0.14 for neuroticism, 0.70 for psychoticism, and 0.56 for the lie scale.

Main Bibliographic Sources

The tool is based on the work of Alexopoulos, D., and Domikopoulou, S. (in preparation), who studied the psychometric properties of the Revised Abbreviated Junior Eysenck Personality Questionnaire for Greek youth. The theoretical and methodological foundation is also supported by the work of Francis, L. J. (1996), who developed the abbreviated English version of the JEPQR-A for children aged 13 to 15 years (Personality and Individual Differences, 21(6), 835–844).
