Correlations of the Myers-Briggs Type Indicator with other Personality and Achievement Variables

Abstract

This study determined correlations among the four scales of the Myers-Briggs Type Indicator and among these and other personality and achievement variables, and predictors of academic performance from personality and aptitude variables. 98 physician assistants and 61 pediatric nurse practitioners completed the Internal-External Locus of Control Scale, Intolerance of Ambiguity Scale, and Myers-Briggs Type Indicator on admission to and graduation from their respective programs. The Otis-Lennon Mental Ability Test and Nelson-Denny Reading Test were also given at admission to the physician assistant program. Grades at admission and graduation were available for both groups, and certifying examination scores were available for physician assistants who reported their scores. IQ, college science grades, and reading-rate predicted final grades at the end of the program and performance on the certifying examination for physician assistants. The Internal-External Locus of Control Scale and Intolerance of Ambiguity Scale predicted final grades at graduation for nurse practitioners.
