These studies agree that the instrument has reasonable construct validity. Four of the studies examined construct validity, but their varying methods did not permit pooling for meta-analysis. This comprehensive literature search identified 221 potential studies, of which seven met our inclusion criteria. No systematic review of the literature or meta-analysis of its validity and reliability has occurred. The Myers-Briggs Type Indicator is frequently used by health professions and educational programs to address the diversity of personalities that exist.
