Performance Validity Tests (PVTs) are specifically designed to assess a lack of effort and the possible simulation of cognitive impairment. In order to ensure the proper allocation of care and resources to this clinical group, it is necessary to correctly distinguish between simulated versus bona-fide cognitive deficits typical of dementia. The rising demographic of older adults worldwide has led to an increase in dementia cases. 4Psychology Department, Campus Duques de Soria, University of Valladolid, Valladolid, Spain.3Centro de Investigação Interdisciplinar Egas Moniz (CiiEM), Instituto Universitário Egas Moniz (IUEM), Caparica, Portugal.2CICPSI, Faculdade de Psicologia, Universidade de Lisboa, Lisbon, Portugal.1Faculdade de Psicologia, Universidade de Lisboa, Lisbon, Portugal.Young (1954) Comparison of the Grassi block substitution test with the Wechsler-Bellevue in the diagnosis of organic brain damage.Ī.M.A.Sandra Fernandes 1,2 * † Inês Ferreira 1 † Luís Querido 1,3 Julia C.

The findings of many studies would support the use of a digit span task for the diagnosis of brain damage (BD) in adult nonpsychotic patients.1-3,6-14 Only one study in which the digit span test could be independently evaluated showed a failure to discriminate between BD Ss and non-BD Ss.5 Despite the rather convincing evidence that digit span performance permits some degree of prediction, a clinician wishing to utilize this test needs more specific information. This study concerns itself with the latter inference. When defective performance on this immediate memory task is observed, the most frequent diagnostic inferences are those of anxiety-induced interference or of impairment associated with a cerebral disorder. The Digit Span Test and the Prediction of Cerebral Pathology The Digit Span Test and the Prediction of Cerebral PathologyĪbstract The use of the auditory-vocal digit span test in clinical examination procedures is based on the assumption that it usefully reflects the status of an important area of intellectual functioning.
