O objetivo deste estudo é apresentar o processo de desenvolvimento e validação de conteúdo do Instrumento de Avaliação Neuropsicológica Breve Infantil NEUPSILIN-INF, que avalia, de modo breve, componentes de oito funções neuropsicológicas em crianças em idade escolar: orientação, atenção, percepção visual, memória, habilidades aritméticas, linguagem, habilidades visuoconstrutivas e funções executivas. O processo envolveu: 1) análise do instrumento original NEUPSILIN e definição das funções e tarefas a serem adaptadas para avaliação neuropsicológica infantil; 2) desenvolvimento de novas tarefas consideradas fundamentais para a avaliação na infância; 3) estudo piloto 1 com a versão preliminar do instrumento; 4) análise de juízes especialistas; 5) estudos piloto 2 e 3, nova reformulação de tarefas do instrumento e elaboração de sua versão final. O instrumento apresentou adequada validade aparente e de conteúdo.The aim of this study is to present the development process and content validation of Child Brief Neuropsychological Assessment Battery NEUPSILIN-INF, which briefly assesses the components of eight neuropsychological functions in school-aged children: orientation, attention, visual perception, memory, arithmetic abilities, language, visuoconstructive abilities and executive functions. The process comprised: 1) the analysis of the original NEUPSILIN instrument and definition of the functions and tasks to be adapted for the child neuropsychological assessment; 2) the development of new tasks considered as fundamental for the assessment in children; 3) pilot study 1 with the preliminary version of the instrument; 4) analysis by specialist judges; 5) pilot studies 2 and 3, new reformulation of the instrument's tasks and preparation of its final version. The instrument presented appropriate face and content validity.

The umbrella-term ‘executive functions’ (EF) includes various domain-general, goal-directed cognitive abilities responsible for behavioral self-regulation. The influential unity and diversity model of EF posits the existence of three correlated yet separable executive domains: inhibition, shifting and updating. These domains may be influenced by factors such as socioeconomic status (SES) and culture, possibly due to the way EF tasks are devised and to biased choice of stimuli, focusing on first-world testees. Here, we propose a FREE (Free Research Executive Function Evaluation) test battery that includes two open-access tasks for each of the three abovementioned executive domains to allow latent variables to be obtained. The tasks were selected from those that have been shown to be representative of each domain, that are not copyrighted and do not require special hardware/software to be administered. These tasks were adapted for use in populations with varying SES/schooling levels by simplifying tasks/instructions and using easily recognized stimuli such as pictures. Items are answered verbally and tasks are self-paced to minimize interference from individual differences in psychomotor and perceptual speed, to better isolate executive from other cognitive abilities. We tested these tasks on 146 early adolescents (aged 9–15 years) of both sexes and varying SES, because this is the age group in which the executive domains of interest become distinguishable and in order to confirm that SES effects were minimized. Performance was determined by Rate Correct Scores (correct answers divided by total time taken to complete blocks/trial), which consider speed-accuracy trade-offs. Scores were sensitive to the expected improvement in performance with age and rarely/inconsistently affected by sex and SES, as expected, with no floor or ceiling effects, or skewed distribution, thus suggesting their adequacy for diverse populations in these respects. Using structural equation modeling, evidence based on internal structure was obtained by replicating the three correlated-factor solution proposed by the authors of the model. We conclude that the FREE test battery, which is open access and described in detail, holds promise as a tool for research that can be adapted for a wide range of populations, as well as altered and/or complemented in coming studies.

O objetivo do presente estudo foi traduzir e adaptar, para o português, o BRIEF. O processo de tradução e adaptação seguiu os passos recomendados na literatura internacional. Além disso, foi realizada uma análise inicial das propriedades psicométricas. A versão final foi administrada numa amostra constituída por 277 pais e 282 professores de crianças entre 5 e 11 anos de idade, 112 adolescentes entre 11 e 18 anos da Cidade do Rio de Janeiro. Os valores dos Alfas de Cronbach oscilaram entre 0,901 e 0,957, considerando as 3 formas. A análise de componentes principais identificou duas dimensões. Os valores de adequada consistência interna encontrados na versão brasileira se assemelham aos da versão original, assegurando boa qualidade do processo de tradução e adaptação.The aim of this study was to translate and adapt the BRIEF into Portuguese. The process of translation and adaptation followed the steps recommended in the international literature. Besides that, an initial analysis of psychometric properties was performed. The final version was administered in a sample of 277 parents, 282 teachers of children between 5 and 11 years old, and 112 adolescents between 11 and 18 years old from the city of Rio de Janeiro. The Cronbach Alphas ranged between .901 and .957 considering the three forms. The main component analysis extracted two dimensions. The internal consistency values found in the Brazilian version resembled the original version, ensuring good quality in the process of translation and adaptation.
