This test was first developed in 1939 by clinical psychologist Starke Hathaway and neuropsychiatrist J.C. The MMPI is probably the most widely used multidimensional tool to help diagnose mental health disorders. This test has multiple versions, contains hundreds of questions, and has been around for decades. It is administered by a trained psychologist or mental health professional who relies upon a series of 10 clinical scales in order to diagnose a patient with mental health or other clinical issues. The Minnesota Multiphasic Personality Inventory (MMPI) is a psychological tool used to assess personality traits and different forms of psychopathology. Scholars have observed unfair racial disparities in scoring the test, and others argue that some of the scales are not scientifically valid. Nevertheless, it does not come without its criticisms. The MMPI-2 is one of the most widely used psychological tools – from treatment plans and the hiring process to law enforcement and marital counseling.

However, there is also a content scale to help provide insight into specific types of symptoms and many other supplemental scales to help increase the validity of this tool.
