The IDRlabs Multiphasic Personality Test (IDR-MPT©) was developed by IDRlabs International. The IDR-MPT was based on the famous scales known from Minnesota Multiphasic Personality Inventory-2 (MMPI-2), a scientifically validated instrument for the assessment of personality pathologies and traits. The test is based on a classic instrument measure developed by the University of Minnesota and is a protected intellectual property not freely available to researchers. IDR-MPT is not associated with any researchers who contributed to the MMPI-2 or their affiliated research institutions. Nor is the IDR-MPT the equivalent of the MMPI-2.

The IDRlabs Multiphasic Personality Test was informed by the personality assessment tool created by Starke R. Hathaway and J. C. McKinley at the University of Minnesota. Though there are numerous comprehensive and well-researched personality inventories in psychological literature, the MMPI-2 is regarded as a classic and well-researched measure with scales that have achieved fame and widespread use; it is generally regarded as possessing good scientific validity. The present test assesses for the presence of eleven different personality domains: Hypochondriasis, Depression, Hysteria, Psychopathic Deviate, Paranoia, Psychasthenia, Schizophrenia, Hypomania, Social Introversion, Masculine Identity, and Feminine Identity. IDRlabs International and the present IDRlabs Multiphasic Personality Inventory have no affiliation with any of the above researchers or their related organizations or academic institutions.

This online personality quiz is based on a valid and reliable tool for the assessment of the psychological traits mentioned above. It is important to keep in mind, however, that free online tests such as this are only preliminary considerations of the multiphasic scales being examined and do not deliver complete assessments of your personality, character, or any unique components of your psychological state. As the publishers of this free online test, which allows you to screen yourself for the presence of eleven functional and dysfunctional domains of personality, we have endeavored to make the test as reliable, valid, and complete as possible by subjecting it to statistical controls and validation.
