Abstract

The aim of this research was to examine the impact of Infrequency scales elevation on the personality inventory, which can refer to malingering, on the memory, visuoperceptual and visuoconstructional tests achievements: Auditory Verbal Learning Test (AVLT), subtest of Logical Memory from Wechsler Memory Scale (WMS), Rey-Osterrieth Complex Figure Test (CFT). In the study 203 participants were included (148 men and 55 women), divided into two groups based on diagnosis: the group with non-psychotic psychiatric disorders (N=110) and the group with brain lesions (N=93). The results on the Minnesota Multiphasic Personality Inventory (MMPI-2) Infrequency scale (F) were used as the base for classification of the participants into groups with valid or invalid profile of the personality inventory. The results show that participants with non-psychotic psychiatric disorder and invalid profile on MMPI-2 achieve statistically significant lower results on memory, visuoperceptual and visuoconstructional tests than participants with non-psychotic psychiatric disorders and valid profile on MMPI-2. Within the group with the brain lesion no significant differences in achievements on these tests between persons with valid and persons with invalid profile on MMPI-2 are found. These results show that in the group with brain lesion it is not justified to use the scale F as an indicator of suboptimal effort in performing cognitive tasks. Also, in the group of nonpsychotic psychiatric disorders lower scores on memory, visuoperceptual and visuoconstructional tests in those with invalid profile are not necessarily reflection of lower efforts in performing these tasks, but could be the consequence of the deeper regression and more acute distress which makes them less effecient on cognitive functions tests as well.
