title: Digit Memory Test: unequivocal cerebral dysfunction and suspected malingering.
abstract: The Digit Memory Test (DMT) (Hiscock & Hiscock, 1989), a forced-choice test for detecting malingering, was administered to 27 patients with unequivocal cerebral dysfunction, 5 patients with postconcussional syndrome, 6 suspected malingerers and 10 normal controls. Results indicate that, even in patients with severe, but static cerebral dysfunction and unequivocal memory disorder, DMT performance is between 95% to 100% correct. By contrast, the 6 patients in whom malingering was seriously considered performed at a level much below the other three groups (74% correct) but not significantly below chance. The DMT may be helpful in evaluating patients suspected of malingering even when they do not score significantly below chance.
