A relação entre memória de trabalho e competência leitora em crianças em risco de transtorno de aprendizagem do Projeto Acerta: um estudo exploratório

Reading and writing are essential rights, which involve individual and social aspects; in addition, these skills are important when it comes to socio economic and political development, critical thinking and an active participation in society (UNESCO 2005). From a neurobiological standpoint, our brain is not prepared for reading, and this practice must be deliberately acquired via instructional guidance (DEHAENE 2009). However, reading disorders and deficits within executive functions, such as low working memory capacity, can make reading arduous. The aim of this study is to investigate the development of reading skills within 45 third grade students from public schools in the city of Natal – RN and its connection to working memory capacity, through information gathered from the Provinha Brasil, data generated from working memory tasks (Portuguese version of AWMA - Automated Working Memory Assessment) and fluid intelligence measures RAVEN. Based on this main objective, we attempted to answer the following research questions: (a) What are the correlations between working memory and reading scores?; (b) What characterizes the relationship between working memory capacity and the risk of reading disabilities amongst the participants in this study?; Following a quantitative research methodology, the Provinhas Brasil from 3rd grade students belonging to the six public schools members of Project ACERTA - Avaliação de Crianças em Risco de Transtornos de Aprendizagem (CAPES/OBEDUC)- were analyzed and compared to the scores from the working memory tests and the fluid intelligence ones. Results indicate that reading skills within children at risk of reading disabilities are directly linked to working memory capacity, especially with regards to the phonological component. It is also evident that the participants with less working memory capacity show more difficulties in the reading abilities that demand interpretation skills. Thus, we intend to contribute to the discussion regarding the diagnosis of reading disabilities and possible intervention strategies.

PERSONALIDADE, ESTILOS PARENTAIS E COGNIÇÃO EM MENINOS VÍTIMAS DE ABUSO SEXUAL

Há um consenso na literatura de que a vivência do abuso sexual na infância ocasiona uma série de consequências, tanto físicas quanto psicológicas, às vítimas. O cenário de violência contra crianças e adolescentes está cada vez mais frequente na sociedade contemporânea, tornando-se um problema de saúde pública, de modo a ser necessário um olhar mais atento dos profissionais e elaboração de políticas públicas tanto para a prevenção dos casos como para o tratamento dos problemas deles decorrentes. Nas crianças, há uma associação do aumento de problemas comportamentais e psicológicos, que podem se estender até o período da idade adulta. Outros estudos enfatizam alterações em áreas cerebrais e as relacionam com o surgimento de transtornos mentais na população de crianças vítimas de violência sexual, dentre outros tipos de violência. O objetivo deste trabalho foi verificar a presença de traços de personalidade, os estilos parentais desenvolvidos e o desempenho cognitivo, especificamente as funções executivas, em meninos com histórico de abuso sexual. Foram avaliadas 62 crianças e adolescentes (32 com histórico de abuso sexual e 30 sem), sendo que no grupo de abuso a idade média dos integrantes é de 11,7 anos de idade e seus genitores majoritariamente divorciados, diferentemente do grupo controle, no qual os genitores são, na maior parte, casados. O método constou de questionário sociodemográfico, testes neuropsicológicos que avaliam as funções executivas (Wisconsin Card Sortint Test, Figuras de Ray e Escala de Inteligência Wechsler para Crianças - Terceira Edição (WISC-III)- Semelhanças, Arranjo de Figuras, Compreensão, Cubos, Dígitos e Vocabulário), Questionário de Personalidade para Crianças e Adolescentes (EPQ-J) e Inventário de Estilos Parentais (IEP). Não houve resultados significativos entre o abuso e as funções executivas, tanto nos subtestes dos Escala de Inteligência Wechsler para Crianças - Terceira Edição (WISC-III) quanto no do Wisconsin; porém o grupo apresentou dados significativamente menores na memória do Figuras Complexas de Rey. Com relação ao EPQ-J, os resultados demonstraram maiores índices de neuroticismo, os quais podem ser associados com sintomas de depressão, e apresentaram menores índices em extroversão, trazendo possíveis dificuldades nas relações sociais. Com relação aos estilos parentais, o grupo apresentou dificuldades e prejuízos nas percepções sobre os genitores, especialmente com relação ao genitor, que é o maior abusador estatisticamente. Os dados mostraram uma correlação entre neuroticismo e vocabulário, estilos parentais e vocabulário, e neuroticismo e estilos parentais. Observou-se a importância de maiores estudos com o público masculino, para que possam ser elucidadas, de forma mais abrangente, as questões de abuso sexual e suas interferências nos aspectos neuropsicológicos, estilos parentais e traços de personalidade, visto que a maior parte dos estudos é relacionada ao público feminino. É necessário o desenvolvimento de políticas públicas para o atendimento específico do público masculino que sofre abuso, e que o profissional da saúde esteja preparado para ajudar, fortalecendo os aspectos psíquicos e emocionais.

Avaliação das Funções Executivas em Dependentes Químicos

The aim of this study was to investigate possible alterations in attentive functions and mental flexibility in individuals diagnosed with Addiction. The sample (n=40) was located for convenience, and included 20 individuals with addiction behaviors (G1), and 20 individuals who do not use harmfully psychoactive substances (G2). Assessment instruments used were: Experimental and Computerized Test of Continuous Performance, and the Wisconsin Card Sorting Test. It was concluded that individuals in the G1 group had a poorer performance in all categories analyzed on the Wisconsin Card Sorting Test and in reaction time on the Experimental and Computerized Test (p<0,05), showing a deficit in mental flexibility and attentive functions, which may have direct implications on addictive behaviors and treatment.

On-line puzzle game based assessment & training for ADHD

Attention-deficit hyperactivity disorder (ADHD) is the most prevalent and impairing neurodevelopmental disorder, with worldwide estimates of 5.29%. ADHD is clinically characterized by hyperactivity-impulsivity and inattention, with neuropsychological deficits in executive functions, attention, working memory and inhibition. These cognitive processes rely on prefrontal cortex function; cognitive training programs enhance performance of ADHD participants supporting the idea of neuronal plasticity. Here we propose the development of an on-line puzzle game based assessment and training tool in which participants must deduce the ‘winning symbol’ out of N distracters. To increase ecological validity of assessments strategically triggered Twitter/Facebook notifications will challenge the ability to ignore distracters. In the UK, significant cost for the disorder on health, social and education services, stand at £23m a year. Thus the potential impact of neuropsychological assessment and training to improve our understanding of the pathophysiology of ADHD, and hence our treatment interventions and patient outcomes, cannot be overstated.

Putting together phylogenetic and ontogenetic perspectives on empathy.

The ontogeny of human empathy is better understood with reference to the evolutionary history of the social brain. Empathy has deep evolutionary, biochemical, and neurological underpinnings. Even the most advanced forms of empathy in humans are built on more basic forms and remain connected to core mechanisms associated with affective communication, social attachment, and parental care. In this paper, we argue that it is essential to consider empathy within a neurodevelopmental framework that recognizes both the continuities and changes in socioemotional understanding from infancy to adulthood. We bring together neuroevolutionary and developmental perspectives on the information processing and neural mechanisms underlying empathy and caring, and show that they are grounded in multiple interacting systems and processes. Moreover, empathy in humans is assisted by other abstract and domain-general high-level cognitive abilities such as executive functions, mentalizing and language, as well as the ability to differentiate another's mental states from one's own, which expand the range of behaviors that can be driven by empathy.

Le profil des récidivistes en matière de conduite avec capacités affaiblies par l’alcool : une étude des caractéristiques neuropsychologiques et psychologiques des contrevenants selon leur sexe

Durant les dernières décennies, les différences intersexes en matière de conduite avec les capacités affaiblies par l’alcool (CCAA) ont suscité l’attention, alors que le comportement est en augmentation chez les femmes tandis qu’il diminue chez les hommes. Les données suggèrent que, chez les femmes, la CCAA s’associe à des caractéristiques psychologiques différentes de celles qui se retrouvent chez les contrevenants masculins (c.-à-d. davantage de problèmes liés à l’alcool et aux drogues et de psychopathologies, mais moins de recherche de sensations et de comportements délinquants). Malgré ce profil différentiel, les femmes contrevenantes de la CCAA demeurent une population hautement méconnue, particulièrement en ce qui a trait au profil des récidivistes. Alors que chez les hommes, des données émergentes indiquent que des limitations cognitives sont présentes chez les récidivistes et qu’elles constituent potentiellement un mécanisme sous-jacent au comportement, le profil cognitif des femmes récidivistes demeure inexploré. Des données exploratoires obtenues chez les contrevenantes et la documentation de champs de recherche connexes suggèrent que les femmes se distinguent notamment en ce qui concerne leur fonctionnement exécutif qui pourrait être préservé, alors que leur fonctionnement visuospatial serait déficitaire en comparaison de leurs vis-à-vis masculins. L’objectif de la présente thèse est d’approfondir les connaissances sur les caractéristiques des femmes récidivistes, ce qui permettra de mieux comprendre l’hétérogénéité de cette population et de générer des hypothèses au regard des mécanismes cognitifs sous-jacents à la répétition du comportement de CCAA. Plus spécifiquement, la thèse a pour objectif premier d’étudier les différences entre les sexes en matière de fonctionnement visuospatial et de mémoire visuelle, d’attention et de fonctionnement exécutif (c.-à-d. flexibilité cognitive, abstraction, inhibition). L’objectif secondaire consiste à comparer ces contrevenants au regard de leurs caractéristiques psychologiques (problèmes liés à l’alcool et aux drogues, impulsivité, recherche de sensations, traits antisociaux, anxiété et dépression). L’hypothèse examinée soutient que les femmes et les hommes récidivistes de la CCAA performent moins bien que les femmes et les hommes non-contrevenants en termes de fonctionnement visuospatial, attentionnel et exécutif. En outre, il est attendu que les femmes récidivistes présentent des performances inférieures à celles des hommes récidivistes en ce qui a trait aux fonctions visuospatiales. Par ailleurs, l’hypothèse prévoit que les hommes récidivistes aient des performances inférieures à celles des femmes récidivistes sur le plan exécutif et attentionnel. En matière de caractéristiques psychologiques, il est attendu que les femmes et les hommes récidivistes présentent significativement plus de problèmes liés à l’alcool et aux drogues, d’impulsivité, de recherche de sensations et d’indices de psychopathologies (tendance antisociale, dépression, anxiété) que les non-contrevenants. En outre, il est attendu que les femmes récidivistes présentent plus de problèmes liés à l’alcool et aux drogues et d’indices de dépression et d’anxiété que les hommes récidivistes. Enfin, il est attendu que les hommes récidivistes présentent significativement plus d’impulsivité, de recherche de sensations et de traits antisociaux que les femmes récidivistes. Ces hypothèses se confirment partiellement, alors que les hommes récidivistes (n = 39) présentent des performances inférieures à celles des hommes non-contrevenants (n = 20) et des femmes récidivistes (n = 20) sur le plan attentionnel et exécutifs. Toutefois, les femmes récidivistes ne se distinguent pas des femmes non-contrevenantes (n = 20) en matière de fonctionnement neuropsychologique. En ce qui a trait aux caractéristiques psychologiques, les résultats soutiennent partiellement les hypothèses. La discussion met en lumière que les femmes et des hommes récidivistes présentent des caractéristiques similaires, hormis en ce qui a trait au fonctionnement attentionnel et exécutif qui semble jouer un rôle dans la récidive au masculin, alors que cela n’apparaît pas être le cas chez les femmes chez qui le comportement pourrait être davantage situationnel. La nécessité que des études futures soient réalisées au moyen de devis expérimentaux, de même que les difficultés inhérentes au recrutement des femmes récidivistes sont discutées.

Sorting Test, Tower Test, and BRIEF-SR do not predict school performance of healthy adolescents in preuniversity education

Executive functions (EF) such as self-monitoring, planning, and organizing are known to develop through childhood and adolescence. They are of potential importance for learning and school performance. Earlier research into the relation between EF and school performance did not provide clear results possibly because confounding factors such as educational track, boy-girl differences, and parental education were not taken into account. The present study therefore investigated the relation between executive function tests and school performance in a highly controlled sample of 173 healthy adolescents aged 12–18. Only students in the pre-university educational track were used and the performance of boys was compared to that of girls. Results showed that there was no relation between the report marks obtained and the performance on executive function tests, notably the Sorting Test and the Tower Test of the Delis-Kaplan Executive Functions System (D-KEFS). Likewise, no relation was found between the report marks and the scores on the Behavior Rating Inventory of Executive Function—Self-Report Version (BRIEF-SR) after these were controlled for grade, sex, and level of parental education. The findings indicate that executive functioning as measured with widely used instruments such as the BRIEF-SR does not predict school performance of adolescents in preuniversity education any better than a student's grade, sex, and level of parental education.

Non-pharmacological interventions for cognitive impairment due to systemic cancer treatment (Review)

Background

It is estimated that up to 75% of cancer survivors may experience cognitive impairment as a result of cancer treatment and given the increasing size of the cancer survivor population, the number of affected people is set to rise considerably in coming years. There is a need, therefore, to identify effective, non-pharmacological interventions for maintaining cognitive function or ameliorating cognitive impairment among people with a previous cancer diagnosis.
Objectives

To evaluate the cognitive effects, non-cognitive effects, duration and safety of non-pharmacological interventions among cancer patients targeted at maintaining cognitive function or ameliorating cognitive impairment as a result of cancer or receipt of systemic cancer treatment (i.e. chemotherapy or hormonal therapies in isolation or combination with other treatments).
Search methods

We searched the Cochrane Centre Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PUBMED, Cumulative Index of Nursing and Allied Health Literature (CINAHL) and PsycINFO databases. We also searched registries of ongoing trials and grey literature including theses, dissertations and conference proceedings. Searches were conducted for articles published from 1980 to 29 September 2015.
Selection criteria

Randomised controlled trials (RCTs) of non-pharmacological interventions to improve cognitive impairment or to maintain cognitive functioning among survivors of adult-onset cancers who have completed systemic cancer therapy (in isolation or combination with other treatments) were eligible. Studies among individuals continuing to receive hormonal therapy were included. We excluded interventions targeted at cancer survivors with central nervous system (CNS) tumours or metastases, non-melanoma skin cancer or those who had received cranial radiation or, were from nursing or care home settings. Language restrictions were not applied.
Data collection and analysis

Author pairs independently screened, selected, extracted data and rated the risk of bias of studies. We were unable to conduct planned meta-analyses due to heterogeneity in the type of interventions and outcomes, with the exception of compensatory strategy training interventions for which we pooled data for mental and physical well-being outcomes. We report a narrative synthesis of intervention effectiveness for other outcomes.
Main results

Five RCTs describing six interventions (comprising a total of 235 participants) met the eligibility criteria for the review. Two trials of computer-assisted cognitive training interventions (n = 100), two of compensatory strategy training interventions (n = 95), one of meditation (n = 47) and one of physical activity intervention (n = 19) were identified. Each study focused on breast cancer survivors. All five studies were rated as having a high risk of bias. Data for our primary outcome of interest, cognitive function were not amenable to being pooled statistically. Cognitive training demonstrated beneficial effects on objectively assessed cognitive function (including processing speed, executive functions, cognitive flexibility, language, delayed- and immediate- memory), subjectively reported cognitive function and mental well-being. Compensatory strategy training demonstrated improvements on objectively assessed delayed-, immediate- and verbal-memory, self-reported cognitive function and spiritual quality of life (QoL). The meta-analyses of two RCTs (95 participants) did not show a beneficial effect from compensatory strategy training on physical well-being immediately (standardised mean difference (SMD) 0.12, 95% confidence interval (CI) -0.59 to 0.83; I2= 67%) or two months post-intervention (SMD - 0.21, 95% CI -0.89 to 0.47; I2 = 63%) or on mental well-being two months post-intervention (SMD -0.38, 95% CI -1.10 to 0.34; I2 = 67%). Lower mental well-being immediately post-intervention appeared to be observed in patients who received compensatory strategy training compared to wait-list controls (SMD -0.57, 95% CI -0.98 to -0.16; I2 = 0%). We assessed the assembled studies using GRADE for physical and mental health outcomes and this evidence was rated to be low quality and, therefore findings should be interpreted with caution. Evidence for physical activity and meditation interventions on cognitive outcomes is unclear.
Authors' conclusions

Overall, the, albeit low-quality evidence may be interpreted to suggest that non-pharmacological interventions may have the potential to reduce the risk of, or ameliorate, cognitive impairment following systemic cancer treatment. Larger, multi-site studies including an appropriate, active attentional control group, as well as consideration of functional outcomes (e.g. activities of daily living) are required in order to come to firmer conclusions about the benefits or otherwise of this intervention approach. There is also a need to conduct research into cognitive impairment among cancer patient groups other than women with breast cancer.

Caracterização e Factores que Influenciam o Desempenho dos Bombeiros Profissionais: estudo exploratório

É indubitável que a decisão está presente no dia-a-dia de todos nós, independentemente do tipo de actividade em que estamos envolvidos. Na vida organizacional, enfrentamos muitas situações que exigem uma resposta momentânea, aqui denominadas de imediatas, as quais não permitem uma recolha de informação adequada, tempo para reflexão, discussão e troca de ideias, entre outras restrições. Além das limitações já citadas por outros autores, como a própria capacidade cognitiva do indivíduo, faculdade de processamento, há outros elementos que influenciam o processo de tomada de decisão, especialmente em ambientes sob pressão e em constante mutação, como é o dos bombeiros. O presente trabalho procura conhecer quais os factores que influenciam a tomada de decisão de bombeiros profissionais com funções de chefia, em ocorrências de incêndios urbanos e acidentes de viação. Neste contexto, foram abordados alguns enquadramentos para a tomada de decisão, como o Modelo da Tomada de Decisão da Primeira Opção Identificada (TDPOI) de Gary Klein, entre outros. No sentido de aprofundar a nossa investigação, foram realizados dois estudos exploratórios através de entrevistas presenciais. A amostra é constituída por 14 profissionais do sector, entre eles bombeiros com funções de chefia, comandantes e delegados sindicais. Os resultados obtidos mostraram que a experiência e a formação são os factores que se evidenciam, e influenciam a decisão dos bombeiros. Constatamos que nos Bombeiros Portugueses a experiência é uma característica dos decisores, pois são eles que farão as opções de alto risco. Por outro lado, apesar de a formação visar a aquisição de competências profissionais, nomeadamente na área da decisão, esta carece de actualização, porque não satisfaz as necessidades dos bombeiros. Apresentam-se também as principais limitações do estudo e sugestões para investigações futuras. / Undoubtedly, the decision is present in day-to-day for us all, regardless of the type of activity we are involved. In organizational life, we face many situations that require a momentary response, here called the immediate, which do not allow collection of adequate information, time for reflection, discussion and exchange of ideas, among other restrictions. Besides the limitations already mentioned by other authors, as the individual's cognitive capacity, processing power, there are other factors that influence the decision-making process, especially in environments under pressure and constantly changing, as is the Fire. This paper seeks to know which factors influence the decision making of professional firefighters with leadership roles in urban fire occurrences and accidents. In this context, we discuss some frameworks for decision making, as the Recognition-Primed Decision (RPD) Model by Gary Klein, among others. In order to further our investigation, two exploratory studies were conducted through personal interviews. The sample consists of 14 professionals, including firefighters with executive functions, commanders and union representatives. The results showed that the experience and training are factors that are evident, and influence the decision of the firefighters. We note that the Portuguese Firemen experience is a characteristic of decision-makers because they are options that will make high-risk. On the other hand, although the training to aim at the acquisition of professional skills, particularly in the area of decision, it needs updating, because it meets the needs of firefighters. We present also the main limitations of the study and suggestions for future investigations.

Étude comparative de la mémoire de source et des faux souvenirs dans la maladie d’Alzheimer et la maladie de Parkinson avec et sans démence

Dans les dernières années, les études sur les maladies neurodégénératives telles que la maladie d’Alzheimer (MA) et la maladie de Parkinson sans démence (MP) et avec démence (MPD) ont été nombreuses, mais la différenciation de ces patients sur la base de leur profil cognitif doit être encore améliorée. Effectivement, l’évaluation clinique peut s’avérer difficile en raison du peu de spécificité dans la présentation de leurs déficits neuropsychologiques. Ceci s’explique par la variabilité et le chevauchement des processus cliniques et pathologiques affectant essentiellement les mêmes régions/fonctions, soit celles liées aux lobes temporaux médians (LTM)/Mémoire (fonction LTM/Mémoire) et aux lobes frontaux (LF)/Fonctions exécutives (fonction LF/Exécutive). Toutefois, il existerait une distinction critique au niveau de l’intégrité relative de ces fonctions dans ces maladies neurodégénératives, ce qui permettrait d’identifier des déficits cognitifs spécifiques à la MA, la MP et la MPD. La présente thèse s’inscrit dans cette volonté de caractériser les profils cognitifs propres à la MA, la MP et la MPD, plus précisément par l’étude novatrice de la mémoire de source et des faux souvenirs. Les quatre chapitres qui composent cette thèse servent donc à documenter la nature de ces mécanismes mnésiques, leurs patrons de performance spécifiques dans la MA, la MP et la MPD, et leur sensibilité aux atteintes des fonctions LTM/Mémoire et LF/Exécutive. Ainsi, le Chapitre I démontre la pertinence d’étudier la mémoire de source et les faux souvenirs dans la MA, la MP et la MPD, en décrivant leurs interactions avec les fonctions LTM/Mémoire et LF/Exécutive, toutes les deux atteintes dans ces maladies. Le Chapitre II, présenté sous forme d’article, révèle des déficits en mémoire de source chez des patients MP, mais seulement dans l’une des tâches employées. Également, malgré des atteintes des fonctions LF/Exécutive et LTM/Mémoire, il est démontré que seule la fonction LTM/Mémoire est liée à l’altération de la mémoire de source chez les patients MP. Le Chapitre III, également sous forme d’article, illustre un taux anormal de faux souvenirs chez des patients MA, tandis que chez des patients MP et MPD, il est démontré qu’ils ont un taux de faux souvenirs comparable à celui des participants contrôles. Il est également rapporté que malgré l’atteinte de la fonction LF/Exécutive chez les patients MA, MP et MPD, elle est seulement liée à l’augmentation des faux souvenirs chez les patients MA. Finalement, dans le dernier Chapitre (IV), les résultats obtenus sont discutés dans leur ensemble à la lumière des prédictions et connaissances actuelles, tout en identifiant les limites afin d’orienter les perspectives de recherche.

La compétence sociale des enfants et des adolescents atteints de déficience motrice cérébrale

Les enfants atteints de déficience motrice cérébrale (DMC) intégrés en milieu scolaire ordinaire vivent davantage de difficultés relatives à la compétence sociale que les autres enfants. En lien avec le modèle SOCIAL de Beauchamp et Anderson (2010) (The socio-cognitive integration of abilities model), deux questions sont abordées afin de comprendre ces difficultés. Dans le premier article, les attributions d’intentions (AI) hostiles sont mesurées par le Home Interview with Child (HIWC), un ensemble de vignettes représentants des situations sociales ambigües. Les résultats montrent que l’acceptation sociale, plus que le statut de naissance, est associé à l’hostilité des AI à 15 ans. Les enfants rejetés et populaires ont un niveau d’AI hostiles supérieur aux enfants de la catégorie d’acceptation sociale moyenne. Il est proposé que l’acceptation sociale soit un médiateur important à considérer dans le développement d’un biais d’AI hostile chez les enfants atteints de DMC. Dans le deuxième article, la dominance sociale (i.e., une forme de leadership) est évaluée dans une situation de résolution de problème en équipe. Les comportements relatifs à la dominance sociale (i.e., les comportements prosociaux et coercitifs) sont codifiés à l’aide d’une grille créée et validée pour cette étude. Les résultats révèlent que, sans égard au score d’acceptation sociale, les enfants atteints de DMC effectuent significativement moins de comportements prosociaux et coercitifs que les enfants sans DMC au cours de la résolution de problème. De plus, leur équipe de travail émet un nombre de comportements prosociaux et coercitifs inférieur à celui observé dans l’équipe des deux enfants témoins. Les difficultés de compétence sociale observées chez les jeunes atteints de DMC pourraient être en partie expliquées par une faible dominance sociale lors d’activités sollicitant les fonctions exécutives. Enfin, les deux articles présentés permettent d’explorer de nouvelles avenues pour comprendre et soutenir le développement de la compétence sociale chez les enfants et les adolescents atteints de DMC. Les interventions auprès de cette clientèle devraient avoir lieu tôt et devraient cibler autant les habiletés motrices de ces jeunes que leur compétence sociale, avant que des signaux clairs ne compromettent déjà leur expérience sociale globale en milieu scolaire ordinaire.

Avaliação breve do défice executivo em pessoas idosas com Acidente Vascular Cerebral: Validação da Bateria de Avaliação Frontal

RESUMO Objetivos: O Acidente Vascular Cerebral (AVC) potencia o desenvolvimento de disfunção executiva, conduzindo a défice no desempenho das tarefas do quotidiano. A avaliação neuropsicológica das funções executivas é importante para desenvolver estratégias de reabilitação adequadas. Assim, são objetivos descrever os dados normativos, precisão de diagnóstico, propriedades psicométricas e análise fatorial da Bateria de Avaliação Frontal (FAB), instrumento breve e de rápida administração, numa amostra de idosos com AVC. Métodos: Inserida no projeto Trajetórias do Envelhecimento de Idosos em Resposta Social, esta investigação conta com uma amostra de 112 pessoas idosas com diagnóstico médico de AVC e 157 pessoas idosas de um subgrupo de controlo sem AVC. Os sujeitos apresentam idades compreendidas entre os 60 e os 100 anos (M = 78,20; DP = 7,57) sendo maioritariamente do sexo feminino (n = 194). A avaliação inclui entrevistas e testes neuropsicológicos agrupados em medidas de funcionamento executivo, medidas cognitivas de referência e medidas clínicas de controlo. Resultados: As variáveis idade e escolaridade interferiram nas pontuações obtidas na amostra clínica, não sendo verificado impacto da variável sexo. Para um ponto de corte de 7, a FAB teve uma sensibilidade de 83,4% e especificidade de 66,1 % (AUC = 0,64); revelou um alfa de Cronbach de 0,79 e correlações fortes com os testes executivos (teste de Stroop, Figura Complexa de Rey, fator Atencional-Executivo do Montreal Cognitive Assessment e Alternância nos testes de Fluência verbal). A análise fatorial confirmatória apontou uma estrutura com um fator. Conclusões: A FAB apresenta boa consistência interna, validade convergente e validade de constructo, aparentando ser uma escala útil para avaliar o défice executivo em pessoas idosas com AVC. Dadas algumas limitações do estudo, que poderão explicar a fraca precisão diagnóstica da FAB, são incentivadas investigações futuras pois a FAB revelou-se um instrumento com propriedades psicométricas promissoras. ABSTRACT Goals: Stroke potentiates the development of executive dysfunction, leading to impairment in performance of daily activities. The neuropsychological assessment of executive functions is important to develop adequate rehabilitation strategies. Thus, describing the normative data, diagnostic accuracy, psychometric properties and factor analysis of the Frontal Assessment Battery (FAB), a brief and easy to administer instrument, in a clinical sample with stroke are objectives of this study. Methods: Being part of the Aging Trajectories of Institutionalized Elderly, this research has a sample 112 elderly people with a medical diagnosis of stroke and a control subgroup of 157 elderly people. The subjects have ages between 60 and 100 years old (M = 78.20, SD = 7.57), mostly females (n = 194). The measurements used include interviews and neuropsychological tests grouped in executive functioning measures, cognitive measures of reference and clinical measures of control. Results: The variables age and education affect the scores obtained in the clinical subgroup, having the variable gender no impact on these. Using a cutoff score of 7, the FAB had a sensitivity of 83.4% and a specificity of 66.1% for screening stroke (AUC = 0.64); showed a Cronbach's α of 0.79, and strong correlations with executive tests (Stroop test, Rey Complex Figure, Attentional-Executive factor of Montreal Cognitive Assessment and Switching in the verbal fluency tests). The confirmatory factor analysis supported a one-factor structure. Conclusions: The FAB presents good internal consistency, convergent, and construct when used for elderly with stroke. Due to some limitations of the study, which may explain the weak discriminant validity, further investigations are encouraged because FAB has showed promising psychometric properties.

Propriedades psicométricas da versão Torga do Teste Stroop

RESUMO Objetivos: Uma nova versão portuguesa do teste Stroop é fundamental para a avaliação neuropsicológica. A versão portuguesa prévia incluía cores que muitas pessoas não conseguiam distinguir. Assim, é objetivo descrever as propriedades psicométricas de uma nova versão, designada versão Torga do Teste Stroop, numa amostra da população portuguesa. Métodos: Inserida no projeto Estudos Normativos de Instrumentos Neuropsicológicos, esta investigação conta com uma amostra global constituída por 544 participantes (241 homens e 303 mulheres) com idades compreendidas entre os 18 e os 97 anos. A avaliação foi realizada com recurso à versão Torga do Teste Stroop, à Figura Complexa de Rey-Osterrieth e à Bateria de Avaliação Frontal enquanto instrumentos de avaliação das funções executivas. Resultados: A versão Torga do Teste Stroop revelou uma consistência interna muito boa (α de Cronbach = 0,99). Revelou também adequada estabilidade temporal e validade convergente. Conclusão: A versão Torga do Teste Stroop aparenta ser um instrumento apropriado à avaliação neuropsicológica de adultos portugueses. Considerando a importância deste teste no contexto da avaliação neuropsicológica, incentivam-se estudos com novas amostras, incluindo amostras clínicas. ABSTRACT Goals: A new Portuguese version of the Stroop Test is essential for the neuropsychological assessment. The previous Portuguese version included colors that many people could not distinguish. Thus, it is aimed to describe the psychometric properties of a new version, called the Torga version of the Stroop Test in a sample of the Portuguese population. Methods: Being part of the Estudos Normativos de Instrumentos Neuropsicológicos/ Normative Studies of Neuropsychological Instruments, this research has a global sample of 544 subjects (241 men and 303 women) aged from 18 to 97 years. The assessment included the Torga version of the Stroop Test, the Rey-Osterrieth Complex Figure and the Frontal Battey Assessment, used as measures of executive functions. Results: The Torga version of the Stroop Test showed a very good internal consistency (Cronbach's α = 0.99). It also revealed an adequate temporal stability and convergent validity. Conclusion: The Torga version of the Stroop Test appears to be an adequate instrument for the neuropsychological assessment of Portuguese adults. Considering the importance of this test in the context of neuropsychological assessment, more studies with new samples, including clinical samples are encouraged.
