Confirmatory Factor Analysis of the Myers-Briggs Type Indicator-Expanded Analysis Report

Abstract

The MBTI-Expanded Analysis is a new personality test based upon the Myers Briggs Type Indicator Form J, which provides 5 subscale scores for each of the four bipolar indices (E/I, S/N, T/F, and J/P) of the MBTI. Confirmatory factor analysis using LISREL 7.13 was performed on test scores from 500 participants in organizational development and career development workshops. Results were cross-validated on an independent sample of 500 from the same subject pool. All 20 subscales had high factor loadings on their respective dimensions, ranging from .44 to .81. Consistent with previous findings, the correlation between the S/N and J/P factors was found to be moderately high, with an estimated true correlation of .59. The E/I and S/N factors were also found to be significantly correlated, with an estimated true correlation of -.36. However, this result could be an artifact of the subject pool used for the analysis. In general, factor loadings were all sufficiently strong to regard all four factors as distinct, well-defined constructs. Although five of the subscales, Gregarious-Intimate, Auditory-Visual, Questioning-Accommodating, Systematic-Casual, and Methodical-Emergent, were shared indicators of other dimensions, all subscales were defined principally by the factor for which they had been constructed.
