ABSTRACT
O teste Memória Lógica da Wechsler Memory Scale - Revised (WMS-R) é amplamente utilizado na prática clínica como instrumento de avaliação da memória verbal. O objetivo deste estudo foi analisar as propriedades psicométricas iniciais de versões alternativas das histórias traduzidas e livremente adaptadas da WMS-R empregadas no Brasil: três histórias equiparáveis à história Ana Soares e três à de Roberto Mota. A amostra foi constituída de 655 universitários, com idades entre 18 e 35 anos. Foi solicitada a recordação livre imediata e tardia (após 30 min) de cada história, original e alternativas. A análise de equivalência entre a recordação imediata e tardia das histórias alternativas e originais mostrou que cinco histórias foram memorizadas de forma equiparável às histórias originais se aplicadas individualmente. A recordação de três pares dessas histórias alternativas também foi equivalente à recordação do par original. Uma análise utilizando a Teoria de Resposta ao Item apontou os itens com melhor índice discriminativo. Assim, propõe-se histórias alternativas às do WMS-R que poderão ser usadas em estudos de normatização.
The Logical Memory test of the Wechsler Memory Scale - Revised (WMS-R) is widely used in clinical practice as a tool for verbal memory assessment. The aim of this study was to examine the initial psychometric properties of alternative versions of the stories translated and freely adapted from WMS -R used in Brazil: three stories comparable to Ana Soares' and three to Roberto Mota's stories. The sample consisted of 655 adults aged between 18 and 35 years. Immediate and delayed free recall of each original and alternative story was requested. The analysis of equivalence between the recall of alternative and original stories showed that five stories proved equivalent to the original stories, if applied individually. Recall of three pairs of these alternative stories was also equivalent to that of the original pair. An analysis using Item Response Theory (IRT) showed the items with best discriminative index. Therefore, the alternative stories proposed here can be used in normalization studies.

The Psychopathology of schizophrenia is composed of many heterogeneous symptom complex, and multifaceted approaches have been done on this subject. It is so simplified a method that the complex symptoms of schizophrenia are classified into only positive and negative symptoms. Preceded studies of other researchers said cognitive deficit of the schizophrenics played important roles in the symptom formation. The purpose of this study is the evaluation of the relationship between the symptoms of schizophrenia and the memory function and low level of cognitive function. In this study, 30 subacute and chronic schizophrenic patients were included. PANSS(Positive and Negative Symptom Scale) was applied to evaluate the clinical symptoms in each subject. The memory function and low level cognitive function were evaluated using WMS-R(Wechsler Memory Scale-revised version) and Decision-reaction timer. The results showed negative correlations between cognitive factor of PANSS(5 factor model) and delayed recall of WMS-R. These results suggest the possibility that symptom evaluation using PANSS can be a preliminary estimation of cognitive function in schizophrenia.
