The M-FAST is a 25-item, doctor-administered, brief structured interview designed to identify individuals who may be over-reporting, exaggerating, or fabricating psychological symptoms. However, the M-Fast is not a psychological test in the sense that it presents any physical material that is administered to a patient. Clearly, the results of the M-Fast are based on the doctor’s subjective observations, rather than the patient’s objective responses and therefore, this measure is not capable of presenting any non-interview objective data to the court. When you find that the doctor discussed the M-Fast in their report you should ask the doctor if the M-Fast has any demonstrably effective methods for measuring the individual’s test-taking attitudes and credibility.

The Minnesota Multiphasic Personality Inventory (MMPI) is a psychological test that is considered the gold standard of test batteries used in medical legal evaluations. The MMPI-2 was published in 1989 and has many proponents who depend on the test’s validity scales to provide information about the individual’s test-taking attitudes and credibility. In fact, the MMPI-2 is the most commonly used version of the MMPI by psychologists and psychiatrists. Every validity and clinical scale performance is described with a T-Score on the MMPI-2 which all have a mean of 50 and a standard deviation of 10. Further, it is well known and universally accepted that T-Scores of 65 or larger are clinically significant or interpretable. In this regard, the K Scale is one of the validity scales of the MMPI-2. T-Scores 65 or higher on the K Scale are associated with the exaggeration of physical disability and distorting the individual’s true psychological condition.
