Incremental Validity of the Myers-Briggs Type Indicator in Predicting Academic Major Selection of Undecided University Students

Abstract
This study examined the incremental validity of the Myers-Briggs Type Indicator (MBTI) as a predictor of academic major choice. Undecided university students were administered the MBTI and Strong Interest Inventory (SII). Their academic major choice was recorded at the end of their fourth semester and categorized as realistic, investigative, artistic, social, enterprising, or conventional. The authors conducted sequential discriminant analyses based on the (a) SII alone and (b) combined use of the SII and MBTI. The SII general occupational theme scales correctly predicted 45.4% of cases, which was significantly better than chance. The hit rate based on the combined use of the SII and MBTI was 48.3%, which was not a significantly higher predictive increment. Implications of these findings for career counselors are discussed.
