The IDRlabs 3 Minute Introversion Test (IDR-3MIT) was developed by IDRlabs. The IDR-3MIT is based on the work of Dr. Robert McCrae and Dr. Paul Costa Jr., who created the Big 5 Personality Inventory. The IDR-3MIT is not associated with any specific researchers in the field of personality psychology or any affiliated research institutions.

The IDRlabs 3 Minute Introversion Test was informed by the Big 5 Personality Inventory criteria for introversion, as published in Costa, Paul & McCrae, R.R. (1999). A five-factor theory of personality. The Five-Factor Model of Personality: Theoretical Perspectives. 2. 51-87. Nordin, M.S. (2012). Confirmatory factor analysis on the big 5 personality test inventory. Southeast Asia Psychology Conference. Laros, J.A., Peres, A.J.S., Andrade, J.M. et al. Validity evidence of two short scales measuring the Big Five personality factors. Psicol. Refl. Crít. 31, 32 (2018).

The work of Dr. McCrae and Dr. Costa has also informed some of the diagnostic criteria in the form of the widely used psychological instrument, the Big 5 Personality Inventory, for clinical use, especially by qualified mental health professionals. The present test is intended for educational purposes only. IDRlabs and the present IDRlabs 3 Minute Introversion Test are independent of the above researchers, organizations, and their affiliated institutions.
