Popularly abbreviated as MMPI, the Minnesota Multiphasic Personality Inventory is a psychological test that assesses personality traits and psychopathology. It was developed by psychologist Donald O. Hebb and his colleagues in the year 1937. The MMPI consists of 550 True/False questions and takes about 60-90 minutes to complete. It also helps in diagnosing conditions like depression, anxiety, and post-traumatic stress disorder (PTSD). It has also been used to screen for things like substance abuse problems.

This 60 item sub-scale evaluates your stress response to both physical and mental factors. It also factors in an individual’s emotional release when exposed to high pressure.

This 50 item measure aspect weighs the intensity of your antisocial behaviors. A higher score on this test may require further assessment for a personality disorder.


Originally, the 56 items in this sub-scale were used to interpret people’s sexuality. Today, it assesses how an individual identifies with societal gender norms.

What To Expect From MMPI?

As such, it’s important, to be honest when taking the test. If you’re not sure about an answer, it’s better to choose “False” than to guess.

Another important thing to remember is that the MMPI does not provide for an official diagnosis of any disorder. If you score higher in any sub-category, your administrator may recommend you for further tests to assess the possibility of a clinical disorder.

How Does It Work?

The MMPI is a true/false test, which means there are no right or wrong answers. Rather, your responses generate a profile of your personality. This happens either through a computer or pen-paper. It takes about 25-40 minutes to administer and evaluate. A clinical psychologist or psychiatrist is in charge of the interpretation of the scoring.
