O teste de simulação de problemas de memória (TOMM)

: um estudo na população portuguesa saudável

Abstract

Introduction: Subjective memory complaints are common in older adults and can be a symptom of neurodegenerative processes. In order to assess the presence of these processes, it is essential to carry out a neuropsychological assessment, but its results are sensitive to simulation. One of the most widely used tests to assess simulation is the TOMM (Test of Memory Malingering), but there is still no normative data for the older Portuguese population. On the other hand, one of the most widely used tests to assess memory is the Logical Memory test, a story recall test. Therefore, the main objective is to study the relationship between these two tests, to see if the TOMM is a good measure for assessing simulation. If it is, it won't correlate with the results of the Logical Memory test. Methodology: A normative sample of the Portuguese population was assessed, consisting of 41 older adults. The assessment protocol included the following instruments: Sociodemographic Questionnaire; Montreal Cognitive Assessment (MoCA); Logical Memory Test; Test of Memory Malingering (TOMM); Subjective Memory Complaints Scale (SMC); Geriatric Depression Scale (GDS-15); and Instrumental Activities of Daily Living Scale (IADL). Results: A statistically significant correlation was found between the TOMM results and the Logical Memory results. Conclusions: Although a relationship was found, there were no scores below the cut-off point on the TOMM, unlike the Logical Memory. In this way, the TOMM seems to be an effective measure for assessing simulation because, otherwise, there would have been scores below the cut-off point in individuals who had scores below the cut-off point in Logical Memory, which meant that they were simulating these deficits. In this sense, the relationship found has little practical significance.
