Confiabilidade do Teste dos Cinco Dígitos em adultos brasileiros

Abstract

RESUMOObjetivo: O presente estudo analisou a confiabilidade do Teste dos Cinco Dígitos (FDT), um instrumento de avaliação dos processos atencionais baseado no paradigma Stroop. O teste usa números e quantidades para avaliação do efeito de interferência atencional. Métodos: Avaliamos 49 adultos brasileiros por meio do FDT. Os participantes realizaram o teste em dois momentos, com aproximadamente duas semanas de intervalo. A confiabilidade do teste foi estimada pela consistência interna (método das metades) e pela avaliação da estabilidade teste-reteste (coeficiente de correlação intraclasse e teste de Wilcoxon para amostras repetidas). Resultados: O tempo de resposta médio dos participantes apresentou discreta melhora nas etapas mais simples do teste e mais acentuada nas etapas mais complexas. A consistência interna do teste foi superior a 0,9. A estabilidade teste-reteste variou em função da etapa do teste, e todas as correlações foram significativas (p < 0,01) e explicaram entre 60% e 90% da variância encontrada. Conclusão: O FDT apresenta evidências robustas de confiabilidade na amostra avaliada. Esse foi o primeiro estudo brasileiro a avaliar essa propriedade pelo método de teste-reteste. Os resultados propiciam melhor aplicabilidade do FDT nos contextos de clínica e pesquisa. ABSTRACTObjective: This study examined the reliability test of the Five Digits (FDT), an assessment tool of attentional processes based on Stroop paradigm. The test uses numbers and quantities for the assessment of attentional interference effect. Methods: We assessed 49 Brazilian adults through FDT. Participants performed the test on two occasions, about two weeks apart. The test reliability was estimated by internal consistency (split-half method) and the evaluation of test-retest stability (intraclass correlation coefficient and Wilcoxon test for repeated measures). Results: The mean response time of the participants showed a slight improvement in the simpler test measures and more pronounced in the more complex ones. The internal consistency of the test was 0.9. The test-retest stability varied depending on the test stage, where all correlations were significant (p < 0.01) and explained between 60% and 90% of the explained variance. Conclusion: FDT provides robust evidence of reliability of the sample investigated. This was the first Brazilian study to evaluate this property by test-retest method. The results provide a better applicability of FDT in clinical and research settings. ARTIGO ORIGINALJ Bras Psiquiatr. 2016;65(2):135-9.Campos MC et al.

Brazilian version of the European Cross-Cultural Neuropsychological Test Battery (CNTB-BR): diagnostic accuracy across schooling levels

“…The score is the time in seconds required to complete each condition in the test. 30 Serial threes is similar to the serial sevens subtest from the MMSE. Participants are required to count down from 20 by threes.…”

“…Table 3 presents the scores of the tasks that make up the FDT, which assesses aspects of executive functioning, such as flexibility and inhibition. The Z-scores of each participant were calculated with reference to the normative data of the Brazilian population (Campos et al, 2016). The only significant difference was the reduction of errors in the counting task, regardless of group (p = 0.029, time factor).…”

“…Another is the fact that different tests were employed, although with the same objective. Seinfeld et al (2013) employed the Stroop Test while, in this study, the researchers opted for the FDT, appropriate for people of any language and reliable for the Brazilian population (Campos et al, 2016). Perhaps the FDT proved to be less sensitive than the Stroop Test.…”
