Folk Concepts and Jung: The Relationship between the California Personality Inventory (CPI) and the MBTI

Abstract

A total of 383 participants (aged 19 to 66 yrs) completed the Myers-Briggs Type Indicator (MBTI) (Myers & McCaulley, 1985) and the California Psychological Inventory-434 (CPI-434) (Gough & Bradley, 1996). The aim was to investigate the relationship between these two measures; the one extremely popular (MBTI) and the other now much less commonly used (CPI). Correlational and regression analysis showed a modest overlap between the two measures. We also explored the higher-order factor structure of the two measures and their relationship. The results seem to indicate that the two tests were measuring different aspects of personality. Limitations are acknowledged.
