Relationship between the MBTI and FIRO-B in a large British sample

Over 4,000 British adults completed two widely used personality-type tests at an Assessment Centre, the Myers-Briggs Type Indicator and the Fundamental Interpersonal Relations Orientation-Behavior. Both correlational and regressional analyses showed modest overlap. Inclusion was related to Introversion-Extraversion and Control to the Thinking-Feeling Dimension. The Sensing-Intuition and Judging-Perceiving dimensions of the Myers-Briggs Type Indicator had only weak correlations with the Fundamental Interpersonal Relations Orientation-Behavior scores (all values below .08). The difference scores between Wanted and Expressed on the Fundamental Interpersonal Relations Orientation-Behavior indicated that the Thinking, Perceiving, Extraverts had the highest differences between Perceived and Wanted scores.
