Assessing the Psychometric Properties of the Dynomight™ MBTI: A Comparative Analysis with the Original Myers-Briggs Type Indicator

Abstract

This study evaluates the validity and reliability of the Dynomight™ MBTI, an innovative adaptation of the Myers-Briggs Type Indicator (MBTI), in comparison with the original MBTI. Employing a quantitative research design, the study involved administering both the original MBTI and the Dynomight™ MBTI to participants from the Tulua institution. The primary objective was to assess the criterion concurrent validity and test-retest reliability of the Dynomight™ MBTI over a 6-week period. Results indicated a high degree of correlation between the two instruments across all personality axes, demonstrating the Dynomight™ MBTI's strong alignment with established MBTI constructs. Notably, the Dynomight™ MBTI's expanded categorization system, which includes a borderline category, addresses key critiques of the original MBTI's binary classification system and reliability concerns. The study found that the Dynomight™ MBTI effectively captures the spectrum and fluidity of personality traits, offering a more inclusive and adaptable approach to personality assessment. The study concludes that the Dynomight™ MBTI represents a significant advancement in personality assessment tools, providing valuable insights for personal development, team dynamics, and psychological research.
