      Abstract

      Resumo O objetivo do estudo foi traduzir, adaptar e investigar propriedades psicométricas da Childhood Executive Functioning Inventory (CHEXI) em uma amostra de crianças brasileiras. Após tradução, adaptação transcultural, retrotradução e equivalência semântica, realizada por juízes da área, a versão brasileira da CHEXI foi respondida por pais e professores de 408 crianças, idades entre 4 e 7 anos, também avaliadas com a Escala de Maturidade Mental Colúmbia e SNAP-IV. Elevados índices de consistência interna foram encontrados. A análise fatorial exploratória gerou dois fatores para a versão brasileira: um fator mais geral de funções executivas e um específico de inibição. As pontuações nas subescalas de planejamento, regulação e, marginalmente, memória de trabalho da CHEXI explicaram de modo significativo o indicador de desatenção da SNAP-IV, enquanto a pontuação na subescala de inibição explicou o indicador de hiperatividade/impulsividade. Os resultados fornecem bons parâmetros psicométricos para a CHEXI, além de contribuir para a realização de estudos com funções executivas e indicadores de TDAH no país.

      Resumen El objetivo del estudio fue traducir, adaptar e investigar las propiedades psicométricas del Childhood Executive Functioning Inventory (CHEXI) en una muestra de niños brasileños. Después de la traducción, adaptación transcultural, retro-traducción y equivalencia semántica realizada por jueces del área, la versión brasileña de la CHEXI fue respondida por padres y maestros de 408 niños de edad comprendida entre 4 y 7 años, también evaluados con la Escala de Madurez Mental Columbia y SNAP-IV. Se encontraron altos índices de consistencia interna. El análisis factorial exploratorio generó dos factores para la versión brasileña: un factor más general de las funciones ejecutivas y un factor específico de inhibición. Las puntuaciones en las subescalas de planificación, regulación y marginalmente memoria de trabajo de la CHEXI explicaron significativamente el indicador de falta de atención de la SNAP-IV, mientras que la puntuación en la sub-escala de inhibición explicó el indicador de hiperactividad / impulsividad. Los resultados proporcionaron buenos parámetros psicométricos para la CHEXI, además de contribuir para la realización de estudios con funciones ejecutivas e indicadores de TDAH en el país.

      Abstract The aim of the study was to translate, adapt and investigate psychometric properties of Childhood Executive Functioning Inventory (CHEXI) for a sample of Brazilian children. After translation, cultural adaptation, back-translation and semantic equivalence performed by area judges, the Brazilian version of CHEXI was answered by parents and teachers of 408 children aged between 4 and 7 years, also evaluated with the Columbia Mental Maturity Scale and SNAP-IV. High internal consistency indices were found. Exploratory factor analysis yielded two factors for the Brazilian version: a more general factor of executive functions and one specific factor of inhibition. The scores on the subscales of planning, regulation and marginally working memory in CHEXI explained significantly the inattention indicator of SNAP-IV, while the score on the inhibition subscale explained the indicator of hyperactivity/impulsivity. The results provide good psychometric parameters for CHEXI, besides contributing to the studies with Executive functions and ADHD signs in Brazil.

      The unity and diversity of executive functions and their contributions to complex "Frontal Lobe" tasks: a latent variable analysis.

      This individual differences study examined the separability of three often postulated executive functions-mental set shifting ("Shifting"), information updating and monitoring ("Updating"), and inhibition of prepotent responses ("Inhibition")-and their roles in complex "frontal lobe" or "executive" tasks. One hundred thirty-seven college students performed a set of relatively simple experimental tasks that are considered to predominantly tap each target executive function as well as a set of frequently used executive tasks: the Wisconsin Card Sorting Test (WCST), Tower of Hanoi (TOH), random number generation (RNG), operation span, and dual tasking. Confirmatory factor analysis indicated that the three target executive functions are moderately correlated with one another, but are clearly separable. Moreover, structural equation modeling suggested that the three functions contribute differentially to performance on complex executive tasks. Specifically, WCST performance was related most strongly to Shifting, TOH to Inhibition, RNG to Inhibition and Updating, and operation span to Updating. Dual task performance was not related to any of the three target functions. These results suggest that it is important to recognize both the unity and diversity of executive functions and that latent variable analysis is a useful approach to studying the organization and roles of executive functions.

        Validity of the executive function theory of attention-deficit/hyperactivity disorder: a meta-analytic review.

        One of the most prominent neuropsychologic theories of attention-deficit/hyperactivity disorder (ADHD) suggests that its symptoms arise from a primary deficit in executive functions (EF), defined as neurocognitive processes that maintain an appropriate problem-solving set to attain a later goal. To examine the validity of the EF theory, we conducted a meta-analysis of 83 studies that administered EF measures to groups with ADHD (total N = 3734) and without ADHD (N = 2969). Groups with ADHD exhibited significant impairment on all EF tasks. Effect sizes for all measures fell in the medium range (.46-.69), but the strongest and most consistent effects were obtained on measures of response inhibition, vigilance, working memory, and planning. Weaknesses in EF were significant in both clinic-referred and community samples and were not explained by group differences in intelligence, academic achievement, or symptoms of other disorders. ADHD is associated with significant weaknesses in several key EF domains. However, moderate effect sizes and lack of universality of EF deficits among individuals with ADHD suggest that EF weaknesses are neither necessary nor sufficient to cause all cases of ADHD. Difficulties with EF appear to be one important component of the complex neuropsychology of ADHD.
