Comprehensive Personality Assessment: Exploring Cattell, Eysenck, Edwards, MMPI & Kernberg

Test Summary

Cattell’s Theory

Cattell believed understanding personality allows us to predict a person’s behavior in specific situations. This contrasts with Freud’s theory, focusing on observable behaviors and correlating them through factor analysis to identify underlying traits.

Eysenck’s Theory

Eysenck’s theory, rooted in psychology and genetics, emphasizes temperament and the influence of heredity on personality. He focused on identifying superfactors, underlying dimensions that explain correlations between traits.

Dimensions

  • Extraversion/Introversion: Sociability and outward vs. inward focus.
  • Neuroticism/Stability: Emotional stability and control vs. instability and reactivity.
  • Psychoticism: Loss of reality contact, impulsivity, and antisocial tendencies.

Eysenck Personality Questionnaire (EPQ)

  • Two scales and four categories.
  • Measures Eysenck’s defined concepts.
  • Categorizes behavior.
  • Scales: Reliability, Neuroticism, Sociability, Psychoticism.

Other Tests

Domino Test

  • Deductive reasoning
  • Logical reasoning
  • Learning potential

Edwards Test

Based on Murray’s theory of needs, this test uses a 225-item questionnaire to assess individual needs and motivations.

Minnesota Multiphasic Personality Inventory (MMPI)

This test measures 19 scales, including clinical, reliability, and additional scales, to assess personality and psychopathology.

Psychometric Testing

Psychometrics aims to objectively measure personality variables and is used in clinical, educational, occupational, and research psychology.

Traits, Disorders, and Normality

This section discusses the difference between traits and disorders, criteria for normality and abnormality, and the distinction between neurosis and psychosis.

Otto Kernberg and Structural Diagnosis

Kernberg’s work focuses on borderline personality organization and structural diagnosis, emphasizing object relations and ego functioning.

DSM-IV

The DSM-IV provides diagnostic criteria for mental disorders, including personality disorders, using a multiaxial system.
