Summary
The Myers-Briggs Type Indicator (MBTI) and Sixteen Personality Factor Questionnaire (16PF) show strong correlations, particularly in Extraversion/Introversion. This validates the MBTI against an alternative personality assessment.
Area of Science:
- Psychology
- Medical Education
Background:
- Family practice residency programs frequently utilize the Myers-Briggs Type Indicator (MBTI) for resident advising.
- The MBTI is a widely used personality assessment tool in various professional development contexts.
Purpose of the Study:
- To validate the Myers-Briggs Type Indicator (MBTI) by comparing its results with an alternative personality evaluation instrument.
- To assess the psychometric properties of the MBTI in the context of medical resident personality assessment.
Main Methods:
- A cohort of 44 residents was evaluated using both the Myers-Briggs Type Indicator (MBTI) and the Sixteen Personality Factor Questionnaire (16PF).
- Correlation coefficients were computed to quantify the relationships between the personality dimensions measured by the two instruments.
Main Results:
- A high correlation (r = -.71) was observed between the Extraversion/Introversion dimensions of the MBTI and the 16PF.
- Significant correlations were also found between MBTI items and the 16PF factors of Tough Poise, Independence, and Superego/Control.
- The Anxiety dimension of the 16PF did not show significant correlations with the MBTI.
Conclusions:
- The Extraversion/Introversion variables measured by the MBTI and 16PF are highly correlated, suggesting construct validity.
- Several other personality variables assessed by the 16PF and MBTI also demonstrate significant correlations, supporting their comparability.
