Personalysis Technical Report - 4 - Convergent and Discriminant Validity with the MBTI

Sep 17, 2026

The purpose of the Personalysis construct validation studies is to evaluate convergent and discriminant validity of Personalysis assessment scales relative to the well-established personality instruments Myers-Briggs Type Indicator (MBTI) and Sixteen Personality Factor Questionnaire (16PF). The report describes construct validity results using both confirmatory and exploratory analyses across Personalysis scales and targeted MBTI scales. Data were collected from 295 MTurkers who completed both instruments.

FAQs

What is the main purpose of the Personalysis construct validation studies?

To evaluate the convergent and discriminant validity of Personalysis assessment scales relative to established personality instruments MBTI and 16PF.

How was the study data collected?

Data were collected from 295 MTurkers who completed both instruments.

What did the report conclude about the Personalysis scales’ construct validity with the MBTI?

Ten of the Personalysis scales showed adequate construct validity with the MBTI, with the majority achieving correlations at or above .19 with theoretically related MBTI scales.
