∗ Its authors call the MMPI a “Psychometric instrument designed ultimately to provide in a single test, scores on all the more important phases of personality.” The test consists of 550 statements printed on separate cards which are sorted by the patient into three categories: True, False and Cannot Say. The scorable items are tabulated on a basic record sheet used to score the different syndromes. The raw scores of a measured trait are translated into a standard score (the T-score), and plotted on a profile chart, the configuration of which is more important than the presence of any one trait to an abnormal degree.Google Scholar
