WHAT THE TEST MEASURES

About This Assessment

Eysenck's Children's Questionnaire, JEPI Test

Junior Eysenck Personality Inventory (JEPI) Test - Symptoms and Signs

type of temperament

In pediatric psychological assessment, a brief self-report can support initial characterization of personality traits and emotional adjustment. The Junior Eysenck Personality Inventory (JEPI) is designed for use with youth and uses a simple yes/no response format.

Developed by Sybil B. G. Eysenck, it consists of 57 items and typically requires about 7 minutes to complete. The measure is intended to assess core personality dimensions commonly described as Extraversion-Introversion and Neuroticism, and it includes a response validity (lie) scale to aid interpretation of response style.

The Junior Eysenck Personality Inventory (JEPI) may be administered individually or in groups and is commonly used as part of a broader evaluation to inform case formulation, screening, and monitoring over time. Results should be interpreted in the context of the referral question, developmental level, and other available clinical information.
