Introdução: A população mundial encontra-se crescentemente envelhecida e entre as queixas mais comuns daqueles que são encaminhados para avaliação neuropsicológica, destacam-se as referentes à memória. A memória associativa, especificamente, tem-se revelado uma área promissora para avaliações mais sensíveis, caracterizando-se pela capacidade de interligar informações previamente não associadas, um processo conhecido como binding. Até ao momento, há poucas provas de memória associativa consideradas exigentes e ecologicamente válidas para a população portuguesa. Neste contexto, surge um paradigma considerado Face-Nome (paradigma multimodal; visual-verbal). Com base neste surgiram diversas provas de memória associativa consideradas promissoras, as quais têm vindo a ser adaptadas e validadas para várias populações. Contudo, em Portugal verifica-se uma escassez de provas de memória associativa exigentes, não havendo até à data nenhuma prova validada baseada no paradigma FaceNome para a população portuguesa. Metodologia: A amostra de conveniência deste estudo transversal foi composta por 58 adultos, sem suspeita de deterioração cognitiva. Aplicou-se uma prova de memória associativa, outras provas cognitivas e questionários de caracterização: MoCA, GDS-15, IADL, TMT A e B, prova de Iniciativa Verbal semântica e fonémica e FNMT. Realizaram-se testes ao coeficiente de correlação Pearson, testes de diferenças, análise dos itens, a análise psicométrica à prova FNMT e um modelo de regressão linear. Resultados: Foram encontradas diferenças entre as várias fases da prova FNMT. A FNMT apresentou validade convergente apropriada, validade divergente parcialmente adequada e boa consistência interna (global). Foi averiguada uma correlação negativa com a idade em várias fases da prova. O modelo de regressão linear refere que a Evocação espontânea diferida da prova pode ser explicada pelo preditor idade. Conclusão: As análises indicam que a construção e as propriedades psicométricas da prova são adequadas, destacando o seu potencial para a avaliação neuropsicológica da memória associativa.
Introduction: The world population is increasingly aging, and among the most common complaints of those referred for neuropsychological assessment are those related to memory. Associative memory, in particular, has been shown to be a promising area for more sensitive assessments, characterized by the ability to link previously unassociated information, a process known as binding. To date, there are few tests of associative memory that are considered demanding and ecologically valid for the Portuguese population. In this context, a paradigm called Face-Name (multimodal paradigm; visual-verbal) emerged. Based on this, various tests of associative memory have emerged which are considered promising, and which have been adapted and validated for various populations. However, in Portugal there is a shortage of demanding associative memory tests, and to date there has been no validated test based on the Face-Name paradigm for the Portuguese population. Methodology: The convenience sample for this cross-sectional study consisted of 58 adults with no suspicion of cognitive deterioration. An associative memory test, other cognitive tests and characterization questionnaires were applied: MoCA, GDS-15, IADL, TMT A and B, semantic and phonemic Verbal Initiative test and FNMT. Pearson correlation coefficient tests, difference tests, item analysis, psychometric analysis of the FNMT test and a linear regression model were carried out. Results: Differences were found between the various phases of the FNMT test. The FNMT showed adequate convergent validity, partially adequate divergent validity and good internal consistency (overall). There was a negative correlation with age at various stages of the test. The linear regression model shows that deferred spontaneous recall of the test can be explained by the predictor age. Conclusion: The analyses indicate that the construction and psychometric properties of the test are adequate, highlighting its potential for the neuropsychological assessment of associative memory.
