Introdução: As queixas subjetivas de memória são frequentes em adultos mais velhos e podem ser um sintoma de processos neurodegenerativos. Para avaliar a presença desses processos, é essencial a realização de uma avaliação neuropsicológica, porém, os seus resultados são sensíveis à simulação. Um dos testes mais utilizados para avaliar a simulação é o TOMM (Teste de Simulação de Problemas de Memória), mas ainda não existem dados normativos do mesmo para a população portuguesa mais velha. Por outro lado, uma das provas mais utilizadas para avaliar a memória é a prova Memória Lógica, uma prova de memória de histórias. Assim, o principal objetivo é estudar a relação entre estas duas provas, para perceber se o TOMM é uma boa medida de avaliação da simulação. Se for, não se correlacionará com os resultados da prova Memória Lógica. Metodologia: Foi avaliada uma amostra normativa da população portuguesa, constituída por 41 adultos mais velhos. O protocolo de avaliação incluiu os seguintes instrumentos: Questionário Sociodemográfico; Montreal Cognitive Assessment (MoCA); Teste Memória Lógica; Teste de Simulação de Problemas de Memória (TOMM); Escala de Queixas Subjetivas de Memória (QSM); Escala de Depressão Geriátrica (GDS-15); e Escala de Atividades Instrumentais de Vida Diária (AIVD). Resultados: Foi encontrada uma relação estatisticamente significativa entre os resultados no TOMM e os resultados na Memória Lógica. Conclusões: Apesar de ter sido encontrada uma relação, não houve resultados abaixo do ponto de corte no TOMM, ao contrário do que aconteceu na Memória Lógica. Desta forma, o TOMM parece ser uma medida eficaz para avaliar simulação porque, caso contrário, teria havido pontuações abaixo do ponto de corte nos indivíduos que tiveram pontuações abaixo do ponto de corte na Memória Lógica, o que significava que estavam a simular esses défices. Neste sentido, a relação encontrada tem pouco significado na prática.
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.
