Abstract: In order for a cognitive test to be reliable and clinically useful, it ought to have validity parameters that will detect subjects who are exaggerating their deficits. This is the first study of which we are aware to systematically evaluate the problem of invalid response patterns in a computerized test battery (CNT) that is widely used in research and clinical practice. We conclude that validity indicators embedded in the CNT computerized test battery can identify “non-credible responders”, i.e., malingerers. Used in conjunction with other tests, the CNT test battery is a quick and efficient way to identify patients who may be malingering cognitive dysfunction. The validity indicators can also be used to exclude invalid test data when the test battery is used in research.
