Resumo
O teste Memoria Logica da Bateria Wechsler Memory Scale- Revised (WMS-R), constituido de duas estorias que devem ser recordadas, e um teste amplamente utilizado na pratica clinica como instrumento de avaliacao da memoria episodica verbal. O principal objetivo desse estudo foi analisar as propriedades psicometricas iniciais de seis estorias alternativas desenvolvidas a partir das estorias originais da referida bateria. A importancia da validacao de versoes alternativas deve-se a necessidade de teste-reteste em pacientes pre e pos-cirurgicos. Assim, as estorias originais e as alternativas foram aplicadas em 655 jovens saudaveis, entre 18 e 35 anos de idade, de instituicoes de ensino superior. As estorias foram aplicadas nas salas de aula, sendo requisitada recordacao imediata e tardia de cada estoria. Foi realizada analise do conteudo da recordacao a fim de estabelecer uma tabela apropriada para a correcao das estorias. Paralelamente, o desempenho dos participantes foi comparado a fim de analisar a equivalencia das versoes alternativas e aplicado o metodo de Analise de Teoria de Resposta ao Item (TRI). Os resultados indicaram que quatro estorias se mostraram equivalentes as estorias originais, se aplicadas individualmente, mas se aplicadas em pares todas as estorias alternativas formam pares equivalentes ao par original. A TRI permitiu destacar quais itens possuem maior indice discriminativo. O presente estudo oferece uma alternativa quanto ao uso de testes de memoria, pois as estorias poderao ser aplicadas repetidamente sem os efeitos da pratica, propiciando dados robustos tanto na pratica clinica como para futuros estudos de normatizacao.
The Logical Memory Test Battery Wechsler Memory Scale -Revised (WMS -R), consisting of two stories that should be remembered, is a widely used test in clinical practice as a tool for assessment of verbal episodic memory. The main objective of this study was to analyze the psychometric properties of the initial six stories alternatives developed from the original stories of that battery. The importance of validation of alternative versions due to the need for test-retest reliability in patients before and after surgery. Thus, the original stories and the alternatives were applied in 655 healthy young , between 18 and 35 years of age, higher education institution. The stories were applied in classrooms, and required immediate and delayed recall of each story. We performed content analysis of memory in order to establish an appropriate table to correct the stories. In parallel, participants' performance was compared in order to examine the equivalence of alternate versions and applied the method of analysis of Item Response Theory (IRT). The results indicated that four stories proved equivalent to the original stories, if applied individually, but if applied in pairs all stories alternative form pairs equivalent to the original pair. The ITR underscored what items are more discriminating index. This study offers an alternative to the use of memory tests, because the stories may be applied repeatedly without practice effects, providing robust data both in clinical practice and for future studies on regulation.
