Why is it that the MMPI-2 is the most widely accepted yet not the best clinical assessment tool on the market?
The MMPI or Minnesota Multiphasic Personality Inventory was first developed in the 1940's and revised to the new version MMPI-2 in the 1980's. Originally developed to help diagnose psychological disorders, the current version of the test is 567 questions which require true, false or cannot say answers. Since the 1980's, research has revealed much more about the brain which is not really reflected in the MMPI-2. The questions asked are often ambiguous, asked several times in the test, and depending on the person and how they INTERPRET the questions, can indicate problems which do not exist. The test also does not measure resiliency, or focus on the normal person as it was designed to find disorders. With so much brain research now saying that disorders are physically brain based, the MMPI-2 is not really the best instrument to assess people clinically.
