          Abstract

          Purpose: The purpose of this study was to translate and cross-culturally adapt the Western Aphasia Battery - Revised (WAB-R) screening test, thus contributing to future applications of the instrument with Brazilian adults. Methods: The adaptation was based on a universalist perspective. The steps for conceptual, item, semantic and operational equivalence were strictly followed, resulting in a short version used in the pretest. The study participants were 30 individuals, between 18 to 89 years old; all were Brazilian speakers, with Portuguese as their first language. However, only 28 volunteers met the criteria for inclusion in the study. Two participants were excluded because they had low scores on the mini-mental state examination and were referred to geriatric assessment. Results: The short version of the WAB-R screening test, used in the pretest, allowed us to observe the behavior and language of the individuals during interactions, to collect impressions of overall communication, and to quantify communication ability by calculating the aphasia quotient and the language quotient, according to parameters of the original instrument. Conclusion: When adapting an instrument, it is important to maintain its original characteristics. However, the properties of measurement may not be in accordance with the psychometric properties of Brazilian culture. Therefore, we propose further analyses of the reliability and validation of the instrument in question in Brazil, which will occur by means of measurement and functional equivalence.

          Objetivo: A proposta deste estudo foi traduzir e adaptar transculturalmente o Teste de Rastreamento Western Aphasia Battery - Revised (WAB-R), colaborando para futura aplicação do instrumento em adultos brasileiros. Métodos: O roteiro de adaptação foi baseado na perspectiva universalista. As etapas de equivalência conceitual e de itens, semântica e operacional foram cumpridas rigorosamente, chegando-se a uma versão síntese usada no pré-teste. Participaram do estudo 30 indivíduos, dos 18 aos 89 anos, todos apresentando o Português Brasileiro como primeira língua. No entanto, apenas 28 voluntários preencheram os critérios de inclusão na pesquisa. Dois participantes foram excluídos, porque apresentaram pontuação baixa no Mini-Exame do Estado Mental, e foram encaminhados para avaliação geriátrica. Resultados: A versão síntese do Teste de Rastreamento WAB-R, usada no pré-teste, permitiu observar o comportamento e a linguagem dos sujeitos em interações, coletar impressões do quadro geral de comunicação e quantificar a habilidade comunicativa de acordo com o cálculo do quociente de afasia e do quociente de linguagem, com parâmetros do instrumento original. Conclusão: Ao se adaptar um instrumento, é importante manter suas características originais. Contudo, as propriedades de medidas podem não estar de acordo com as propriedades psicométricas da cultura brasileira. Sendo assim, propõe-se a análise da confiabilidade e validação no cenário brasileiro, que ocorrerão na equivalência de mensuração e funcional.

          What is right-hemisphere contribution to phonological, lexico-semantic, and sentence processing? Insights from a meta-analysis.

          To evaluate the relative role of left and right hemispheres (RH) and describe the functional anatomy of RH during ortholinguistic tasks, we re-analyzed the 128 papers of a former left-hemisphere (LH) meta-analysis (Vigneau et al., 2006). Of these, 59 articles reported RH participation, providing 105 RH language contrasts including 218 peaks compared to 728 on the left, a proportion reflecting the LH language dominance. To describe inter-hemispheric interactions, in each of the language contrasts involving both hemispheres, we distinguished between unilateral and bilateral peaks, i.e. having homotopic activation in the LH in the same contrast. We also calculated the proportion of bilateral peaks in the LH. While the majority of LH peaks were unilateral (79%), a reversed pattern was observed in the RH; this demonstrates that, in contrast to the LH, the RH works in an inter-hemispheric manner. To analyze the regional pattern of RH participation, these unilateral and bilateral peaks were spatially clustered for each language component. Most RH phonological clusters corresponded to bilateral recruitment of auditory and motor cortices. Notably, the motor representation of the mouth and phonological working memory areas were exclusively left-lateralized, supporting the idea that the RH does not host phonological representations. Right frontal participation was not specific for the language component involved and appeared related to the recruitment of attentional and working memory areas. The fact that RH participation during lexico-semantic tasks was limited to these executive activations is compatible with the hypothesis that active inhibition is exerted from the LH during the processing of meaning. Only during sentence/text processing tasks a specific unilateral RH-temporal involvement was noted, likely related to context processing. These results are consistent with split-brain studies that found that the RH has a limited lexicon, with no phonological abilities but active involvement in the processing of context.

            Mini-Exame do Estado Mental: características psicométricas em idosos ambulatoriais

            OBJETIVO: Avaliar as características de medida do Mini-Exame do Estado Mental em idosos atendidos em um ambulatório geral. MÉTODOS: O total de 303 indivíduos (>65 anos) foi submetido à avaliação geriátrica com vários instrumentos, inclusive o Mini-Exame do Estado Mental. Foram calculadas a sensibilidade, a especificidade, os valores preditivos positivo e negativo e a curva ROC. RESULTADOS: A sensibilidade, a especificidade, os valores preditivos positivo e negativo e a área sob a curva ROC foram 80,8%, 65,3%, 44,7%, 90,7% e 0,807, respectivamente (ponto de corte 23/24). O melhor ponto de corte para indivíduos analfabetos foi 18/19 (sensibilidade =73,5%; especificidade =73,9%), e para aqueles com instrução escolar foi 24/25 (sensibilidade =75%; especificidade =69,7%). CONCLUSÕES: Para o rastreamento cognitivo de idosos atendidos em ambulatórios gerais pelo Mini-Exame do Estado Mental, a escolaridade deverá ser considerada para a adoção do ponto de corte mais adequado.
