The test has 10 different scales, which are numbered 0 through 9. Nor are all of these practitioners qualified they must have undergone specific training before being certified to administer the MMPI. A psychiatrist or clinical psychologist must administer and interpret the test. These latter uses have proven to be highly controversial.Ĭurrently the test consists of 567 questions. It is also used in criminal defense cases and to screen candidates for certain high-risk jobs. The MMPI may be the most frequently given test in the field of psychology. It was developed at the University of Minnesota. The test is designed to determine the structure of a person's personality and to identify psychopathology. If a psychological test could be used in your case, it’s crucial you work with an attorney who has the experience and background to challenge the validity of that test, if necessary, or to contextualize the results.The Minnesota Multiphasic Personality Inventory, or MMPI, is a personality test that was developed by Dr. Those brochures used to tout the scientific validity of the tests they were advertising, but “by the end of the 1990s those numbers had disappeared.” But this isn’t happening, the researchers concluded.Ī Stanford University law professor who was not involved in the study told the Associated Press that he commonly receives unsolicited advertising catalogs for new psychological tests. Courts are responsible for ensuring that any evidence used to convict someone is scientifically valid. Lawyers are supposed to help the courts weed out junk science and keep it from being admitted as evidence. Unfortunately, lawyers only challenged the validity of a psychological test in less than 3% of all the cases. Almost a quarter were deemed by the manuals to be unreliable as evidence. Of those that had been reviewed in the manuals, only 40% ended up being reviewed favorably. Of those, a third had never been reviewed in the field’s leading manuals, meaning that they probably are not widely accepted in their field. Indeed, the researchers found hundreds of different psychological tests being used in courtrooms across the U.S. Not such good news, the second most common psychological test being admitted into evidence in those cases was the Rorschach “ink blot” test, which is widely considered dangerously ambiguous and subjective, according to the researchers. The most commonly used psychological test in those cases was the MMPI, which is good news. From the MMPI to the Rorschach and beyondįor the study, researchers pored over 876 court cases that took place in the United States between 20. That is unfortunate, because the results of a courtroom psychological test could affect the outcome of a criminal or family law case. Yet, according to a study earlier this year, courts often don’t filter out psychological tests that lack sufficient scientific underpinnings and wide acceptance in the field. By law, courts are only supposed to allow scientific and technical evidence that is 1) widely accepted within the field and 2) backed up by science - not pseudoscience. If you said you’d prefer to see the scientifically valid test used in court, you’re right. They’re generally not developed by psychologists and have no scientific underpinnings. On the other end of the spectrum, you might think about the kinds of personality tests you find on Facebook. ![]() First developed in the 1940s, the test is widely considered to be scientifically valid. This is a standardized test that is routinely used to help determine if someone is suffering from a diagnosable psychological problem. ![]() You may have heard of the Minnesota Multiphasic Personality Inventory, or MMPI.
