Sleep problems are common in children and adolescents, particularly those with Neurodevelopmental Disorders. With the changes in daily habits resulting from the COVID-19 pandemic, we have analyzed sleep characteristics, during social isolation, in Brazilian children and adolescents aged between 4 and 12 years with Autism Spectrum Disorder (N = 267), Down Syndrome (N = 74), and typical development (N = 312). The ASD group presented with worse indicators of sleep habits in the Children's Sleep Habits Questionnaire (CSHQ-BR) and fell asleep later during the pandemic. The entire group started fall asleep and waking up later during the pandemic - as well as waking up more often during the night. These results may contribute to parental guidance and sleep habit-related interventions during and after the COVID-19 pandemic.

To translate to Brazilian Portuguese, culturally adapt and confirm the psychometric parameters of validity and reliability of the Children's Sleep Habits Questionnaire (CSHQ-BR) in children.A sample of 314 typically developing children, 51% girls, mean age 7.12 years (SD = 2.04 years) were assessed, comprising 227 from São Paulo and 87 from the Amazon region. Translation, back translation, cultural adaptation, a pilot study and item review were carried out, yielding the final version of the CSHQ. Psychometric parameters were determined based on content validity coefficient (CVC), test-retest, internal consistency, evidence of convergent validity and internal structure.The final CVC for the scale was 0.88. Intraclass correlation was 0.98 for the overall questionnaire and ranged from 0.88 to 0.98 for subscales. CSHQ-BR internal consistency was α = 0.81 for the CSHQ-BR total score (95% CI) and from 0.51 to 0.75 for subscales. Exploratory factor analysis suggested a novel 4-factor structure. A positive correlation was found between the CSHQ and the Questionnaire on Sleep Behavior. Mean total CSHQ score in Brazilian children was 46.85 (SD = 9.43), and boys had a higher mean total score than girls, although not statistically significant.The CSHQ-BR exhibited satisfactory equivalence for the original English abbreviated form and the Brazilian Portuguese version, proving a useful sleep screening instrument for identifying sleep problems in Brazilian children aged 4-10 years.

Given the importance of the environment for the development of the theory of mind (ToM) in childhood, as well as the scarcity of studies in low-income Latin American countries, we aimed to investigate the relation between family environment characteristics and performance in ToM tasks in a group of Brazilian children. A total of 49 children participated, whose ages ranged between 3 and 5 years (

Some children with Autism Spectrum Disorder (ASD) experience the loss of previously acquired abilities, especially that of using words, a phenomenon that is still poorly understood. This study aimed to investigate parents’ perceptions of the age of word acquisition and word loss in individuals with ASD as compared to children with Down Syndrome (DS) and those with typical development (CG). Parents of 77 individuals with ASD, 33 with DS, and 63 from CG completed an inventory on the loss of words and developmental abilities. The median age of acquisition of the first words was 14 months for the ASD group, approximately 4 months after those in CG, and 23 months for the SD group. Word loss occurred only in the ASD group (36.4%). The median age of loss was 18 months. Parents’ perception of word loss can contribute to the understanding of this phenomenon as a potential early ASD indicator. Resumo Algumas crianças com Transtorno do Espectro Autista (TEA) apresentam perda de habilidades previamente adquiridas, especialmente a de utilização de palavras, fenômeno ainda pouco compreendido. O objetivo deste estudo foi investigar a percepção dos pais sobre a idade de aquisição e perda de palavras em indivíduos com TEA, comparados a crianças com Síndrome de Down (SD) e desenvolvimento típico (GC). Pais de 77 indivíduos com TEA, de 33 com SD e 63 do GC preencheram um inventário sobre perda de palavras e habilidades de desenvolvimento. A mediana da idade de aquisição das primeiras palavras foi 14 meses no TEA, em torno de quatro meses após o GC, e 23 meses no grupo SD. A perda de palavras ocorreu apenas no grupo TEA (36,4%). A mediana da idade da perda foi 18 meses. A percepção dos pais sobre a perda de palavras pode contribuir para o entendimento desse fenômeno como um potencial indicador precoce do TEA.

RESUMO Tendo em vista que o desempenho acadêmico é um dos fatores associados ao bom prognóstico no Transtorno do Espectro Autista (TEA), este estudo avaliou diferentes aspectos cognitivos da leitura em oito meninos com TEA, entre 10 e 13 anos (M=10,87; DP=1,12), de escolas públicas e privadas. Avaliou-se o reconhecimento de palavras (TCLPP II), a fluência (TFL) e a compreensão de leitura (TCCL), bem como o Quociente de Inteligência (QI) Estimado (Vocabulário e Raciocínio Matricial do WASI). Os resultados demonstram frequência maior de desempenhos abaixo da média em compreensão de leitura e maior frequência de desempenhos na média tanto no reconhecimento de palavras quanto na fluência de leitura. Em relação ao tempo nas tarefas de fluência e compreensão, houve maior frequência de classificações na média. Não houve correlação significativa entre Vocabulário do WASI e o QI com os testes de leitura. Entretanto, houve correlação positiva, significativa e de alta magnitude entre reconhecimento de palavras com os escores em fluência e compreensão. Uma tendência de magnitude moderada foi observada entre essas duas últimas variáveis. Conhecer o perfil de leitura do aluno com TEA, a partir da avaliação do reconhecimento de palavras, da fluência e da compreensão, possibilita orientar adaptações escolares, com impacto no seu desenvolvimento acadêmico e prognóstico. ABSTRACT Considering that academic performance is one of the factors associated with a good prognosis in the Autism Spectrum Disorder (ASD), this study evaluated different cognitive aspects of reading in 8 boys with ASD, between 10 and 13 years old (M=10.87; SD=1.12), of public and private schools. Word recognition (TCLPP II), fluency (TFL) and reading comprehension (TCCL) were evaluated, as well as Estimated IQ (Vocabulary and Matrix Reasoning of the WASI). The results demonstrate a higher frequency of below-average performances in reading comprehension skills, higher frequency of performances on average in word recognition and reading fluency. Regarding the time on fluency and comprehension tasks, there was a higher frequency of average classifications. There was no significant correlation between the Vocabulary and the IQ with the reading tests. However, there was a positive, significant and high magnitude correlation between word recognition with fluency and comprehension scores. A trend of moderate magnitude was observed between these last two variables. The knowledge about the reading profile of students with ASD obtained from the assessment of word recognition, fluency and comprehension makes it possible to guide school adaptations, with an impact on their academic development and prognosis.

Background: This study developed a photo and video database of 4-to-6-year-olds expressing the seven induced and posed universal emotions and a neutral expression. Children participated in photo and video sessions designed to elicit the emotions, and the resulting images were further assessed by independent judges in two rounds.Methods: In the first round, two independent judges (1 and 2), experts in the Facial Action Coding System, firstly analysed 3,668 emotions facial expressions stimuli from 132 children. Both judges reached 100% agreement regarding 1,985 stimuli (124 children), which were then selected for a second round of analysis between judges 3 and 4.Results: The result was 1,985 stimuli (51% of the photographs) were produced from 124 participants (55% girls). A Kappa index of 0.70 and an accuracy of 73% between experts were observed. Lower accuracy was found for emotional expression by 4-year-olds than 6-year-olds. Happiness, disgust and contempt had the highest agreement. After a sub-analysis evaluation of all four judges, 100% agreement was reached for 1,381 stimuli which compound the ChildEFES database with 124 participants (59% girls) and 51% induced photographs. The number of stimuli of each emotion were: 87 for neutrality, 363 for happiness, 170 for disgust, 104 for surprise, 152 for fear, 144 for sadness, 157 for anger 157, and 183 for contempt.Conclusions: The findings show that this photo and video database can facilitate research on the mechanisms involved in early childhood recognition of facial emotions in children, contributing to the understanding of facial emotion recognition deficits which characterise several neurodevelopmental and psychiatric disorders.

RESUMO Objetivo: investigar as propriedades psicométricas de um teste de desempenho para avaliação de reconhecimento de palavras e de um checklist de autorrelato de dificuldades de leitura/indicadores de dislexia, em uma amostra de adultos. Métodos: foram avaliados 54 sujeitos, idades entre 18 e 57 anos (M=24,16; DP = 7,34), com Ensino Médio completo ou cursando a graduação. As avaliações foram realizadas utilizando o Teste Computadorizado de Competência de Leitura de Palavras para Adultos (TCLP-2) e o questionário de autorrelato Adult Dyslexia Checklist (ADC). Resultados: não foram observadas diferenças de desempenho em função da escolaridade e do gênero. O tempo de resposta foi menor no julgamento dos itens Corretos do TCLP-2 em relação aos itens incorretos (inversão, troca fonológica, erro ortográfico e pseudopalavra homófona). 18,5% dos participantes relataram dificuldades mais severas no ADC. Análise de grupos extremos mostrou que participantes com maiores pontuações/dificuldades no ADC tiveram pior desempenho nos itens Corretos do TCLP-2. Análise fatorial retornou solução com fator único para tipos de itens do TCLP-2. Dados de precisão se mostraram adequados para ambos os instrumentos, com valores de Spearman-Brown e alfa de Cronbach maiores que 0,70. Relações de baixa a moderadas foram observadas entre os dois instrumentos, provendo evidências de validade a ambos. Conclusão: o estudo apresentou dados psicométricos de dois instrumentos para avaliação de leitura em adultos. Ambos mostraram índices satisfatórios de precisão e evidências de validade por relação com outras variáveis. Frente à carência de instrumentos padronizados para avaliação de leitura em adultos no contexto nacional, o estudo estende sua contribuição à futura instrumentalização desta área. ABSTRACT Purpose: to investigate the psychometric properties of a performance test for assessment of word recognition and a self-report checklist for reading difficulties/ dyslexia indicators in adults. Methods: a total of 54 subjects aged 18-57 years (M = 24.16, SD = 7.34) who had complete high school or were enrolled in college were investigated. The following instruments were used: the Word Reading Competency Test for Adults (WRCT-2), and the self-report questionnaire Adult Dyslexia Checklist (ADC). Results: there were no differences in the participants' performance in terms of educational level or gender. Response time of WRCT-2 items was shorter for the Correct Word items than for the incorrect ones (Inversion, Phonological Exchange, Misspelling, and Pseudo-homophone). Of the 54 participants, 18.5% reported greater difficulties on the ADC. Analysis of the extreme groups showed that the participants with higher scores or difficulties on the ADC had poorer performance on the Correct Word items of the WRCT-2. Factor analysis resulted in a one-factor solution for the WRCT-2 items. Spearman-Brown and Cronbach's alpha values greater than 0.70 indicated good reliability of the instruments used. Low to moderate correlation between the instruments provided evidence of validity to both of them. Conclusion: this study presents psychometric data from two adult reading assessment instruments. Both instruments had satisfactory validity and reliability. Given the lack of national standardized instruments for adult reading assessment, the present study contributes to the development of future instrumentation for this field.

Resumo O estudo investigou a relação de variáveis ambientais (nível socioeconômico, ambiente familiar e frequência à pré-escola) com vocabulário em pré-escolares e desempenho posterior em leitura/escrita. Participaram 68 crianças (Idade média = 4,4 anos) de uma escola pública de Educação Infantil e suas respectivas famílias. Utilizou-se o Teste de Vocabulário Auditivo; pais responderam a um questionário de identificação e à escala ABEP. O inventário HOME foi utilizado para a coleta de informação sobre o ambiente familiar. Seis meses depois, o Teste de Leitura e Escrita foi aplicado. Houve melhor desempenho em vocabulário e em leitura/escrita com a progressão escolar e relação moderada entre essas variáveis. Escolaridade materna relacionou-se ao vocabulário e o tempo de frequência à pré-escola com a escrita. Aspectos específicos do ambiente familiar, como os estilos de interação e variedade de estimulação, associaram-se com vocabulário receptivo. O estudo colabora com a investigação sobre como variáveis do meio podem associar-se ao desenvolvimento linguístico infantil.

Scales with evidence of validity and reliability are important to evaluate child development. In Brazil, there is a lack of standardized instruments to evaluate young children. This study investigated the psychometric properties of the Bayley Scales of Infant Development, Third Edition (Bayley-III). It was translated into Brazilian Portuguese, culturally adapted and tested on 207 children (12-42 months of age). Evidence of convergent validity was obtained from correlations of the Bayley-III with the: Peabody Developmental Motor Scale 2, Leiter International Performance Scale-R, Expressive Vocabulary Assessment List and Peabody Picture Vocabulary Test. Exploratory factor analyses showed a single component explaining 86% of the variance, supported by goodness-of-fit indexes in confirmatory factor analysis. The Bailey-III demonstrated good internal consistency with alpha coefficients greater than or equal to .90 and stability for fine motor scale only. These robust psychometric properties support the use of this tool in future national studies on child development. Resumo Escalas com evidências de validade e precisão são importantes para avaliação do desenvolvimento infantil. No Brasil, há escassez de instrumentos padronizados e normatizados para a primeira infância. Este estudo investigou as propriedades psicométricas da Bayley Scales of Infant and Toddler Development, terceira edição (Bayley-III) que foi traduzida, adaptada para o português e testada com 207 crianças (12-42 meses). Evidências de validade convergente foram observadas entre a Bayley-III e: Peabody Developmental Motor Scale-2, Escala Internacional de Inteligência Leiter-R, Lista de Avaliação de Vocabulário Expressivo e Teste de Vocabulário por Imagens-Peabody. Análise fatorial exploratória indicou componente que explica 86% da variância, corroborado por bons índices de ajustes na análise fatorial confirmatória. A Bayley-III apresentou boa consistência interna com coeficientes alfa a partir de 0,90 e boa estabilidade teste-reteste apenas para a escala motora fina. Estas adequadas propriedades psicométricas podem contribuir para o avanço nas pesquisas em contexto nacional na área de avaliação do desenvolvimento infantil.

Eye movements help to infer the cognitive strategy that a person uses in fluid intelligence tests. However, intelligence tests demand different relations/rules tokens to be solved, such as rule direction, which is the continuation, variation or overlay of geometric figures in the matrix of the intelligence test. The aim of this study was to understand whether eye movements could predict the outcome of an intelligence test and in the rule item groups. Furthermore, we sought to identify which measure is best for predicting intelligence test scores and to understand if the rule item groups use the same strategy. Accordingly, 34 adults completed a computerized intelligence test with an eye-tracking device. The toggling rate, that is, the number of toggles on each test item equalized by the item latency explained 45% of the variance of the test scores and a significant amount of the rule tokens item groups. The regression analyses also indicated toggling rate as the best measure for predicting the score and that all the rule tokens seem to respect the same strategy. No correlation or difference were found between baseline pupil size and fluid intelligence. Wiener Matrizen-Test 2 was demonstrated to be a good instrument for the purpose of this study. Finally, the implications of these findings for an understanding of cognition are discussed.

Objective: In schizophrenia, scores reflecting deficits in different cognitive processes are strongly correlated, making it difficult to establish a solid relationship between different cognitive mechanisms and other features of this disorder. The objective of this study was to explore whether three frequently postulated executive functions (updating, shifting, and inhibition) could be compared between groups and considered independently in terms of their respective roles in functional outcome. Methods: This study relied on confirmatory factor analysis of schizophrenia patients (n=141) and healthy controls (n=119). The main analyses examined the degree to which three executive functions (updating, set-shifting, and inhibition) could be separated in schizophrenia and compared this model among groups. Structural equation modeling analysis was also performed to examine the extent to which executive function components contribute to functional outcome in schizophrenia. Results: Multiple-group confirmatory factor analysis with unconstrained model parameters indicated that the full three-factor model may fit the data in both groups (χ2 = 61.48, degrees of freedom = 34, p < 0.001, comparative fit index = 0.95; standardized root mean square residual = 0.037; root mean square error of approximation = 0.04; Akaike’s information criteria = 169.49; normed fit index = 0.90), although there was also a good data fit for the patient group with a two-factor model. In the patient group, structural equation modeling suggested that shifting and (principally) updating were associated with the general measure of functional outcome (regression path coefficients: 0.34, p < 0.005; 0.39, p < 0.005, respectively), although when combined the mechanisms fail to contribute. Conclusion: This data suggests that the factor structure may be similar but not identical between groups, and both updating and shifting may play an important role in functional outcome in schizophrenia.

The family environment may impact child development. However, investigating the family environment in Brazil can be a challenge due to the lack of appropriate instruments. To systematize the study of family environment the Home Observation for Measurement of the Environmen. In ventory (HOME) was developed. The executive functions (EF), important for the control of thinking, behavior and emotion are among the skills affected by variables of the family environment. This study investigated reliability and validity evidences of the Brazilian Early Childhood version of the HOME (EC-HOME). Participants were 63 preschoolers (M=4.41y, SD=0.66), and their respective families. Children were evaluated in EF tasks. Parents responded to an identification and socioeconomic status (SES) questionnaire. Home visits were conducted to apply the EC-HOME, with independent scoring by two evaluators for 20 of them. There was a high interrater agreement and satisfactory Cronbach's alpha coefficient for the total scale. Correlation analysis suggested that the domains of the HOME contain relatively independent contents of the family context. Significant correlations of the HOME domains with SES variables, as well as with children performance in EF tasks, were found. Findings provided some preliminary evidences of validity and reliability of the EC-HOME in a Brazilian sample. Resumo O ambiente familiar pode impactar o desenvolvimento infantil. Porém, investigar o ambiente familiar no Brasil pode ser um desafio devido à falta de instrumentos adequados. Para sistematizar o estudo do ambiente familiar foi desenvolvido o Home Observation for Measurement of the Environment Inventory (HOME). Dentre as habilidades afetadas por variáveis do ambiente familiar estão as funções executivas (FE), importantes para o controle do pensamento, comportamento e emoção. Este estudo investigou evidências de validade e fidedignidade da versão Early Childhood (EC-HOME) brasileira do HOME. Participaram 63 pré-escolares (M=4,41 anos, DP=0,66), e suas respectivas famílias. As crianças foram avaliadas em tarefas de FE. Os pais responderam um questionário de identificação e de nível socioeconômico (NSE). Visitas domiciliares foram realizadas para aplicar o EC-HOME, com a pontuação independente por dois avaliadores para 20 delas. Observou-se alta concordância entre avaliadores e coeficiente Alpha de Cronbach satisfatório para a escala total. Análise de correlação sugeriu que os domínios do HOME contemplam conteúdos relativamente independentes do contexto familiar. Correlações significativas entre domínios do HOME com variáveis de NSE, assim como com desempenho das crianças nas tarefas de FE, foram encontradas. Achados fornecem algumas evidências preliminares de validade e fidedignidade do EC-HOME em amostra brasileira. Resumen El entorno familiar puede afectar el desarrollo infantil.

Objective This study describes the development of two updating measures of working memory (WM): Letter Updating Test (LUT) and Word Updating Test (WUT). Methods In stage 1, items were created and the instruments were assessed by experts and laymen. In stage 2, tests were given to 15 patients with schizophrenia and 15 paired controls. All were able to understand and respond to the instruments. In stage 3, 141 patients with schizophrenia and 119 healthy controls aged 18 to 60 took part; they were assessed on WM, processing speed (PS) and functional outcome. Results The results showed adequate rates of internal consistency for both measures developed, for both the total sample and each group separately, as well as evidence of convergent validity, discriminant validity and sensitivity to differentiate performance among the groups. Principal component analysis yielded two components, one for updating tests and other for PS measures, indicating factorial validity. Positive and significant, yet low, correlations were found with functionality measures. Conclusion These results provide adequate psychometric parameters for the measures developed, applicable to cognitive research settings in schizophrenia. Objetivo O estudo descreve o desenvolvimento de duas medidas de atualização da memória de trabalho (MT): Teste de Atualização de Letras (TAL) e Teste de Atualização de Palavras (TAP). Métodos Na etapa 1 foram criados itens e os instrumentos foram analisados por experts e leigos. Na etapa 2, os testes foram aplicados em 15 pacientes com esquizofrenia e 15 controles pareados. Todos foram capazes de compreender e responder aos instrumentos. Na etapa 3, participaram 141 pacientes com esquizofrenia e 119 controles saudáveis com idades entre 18 e 60 anos, avaliados em MT, velocidade de processamento (VP) e funcionalidade. Resultados Os resultados revelaram bons índices de consistência interna para ambas as medidas desenvolvidas, tanto para a amostra total como para cada grupo separadamente, bem como evidências de validade convergente com medidas de MT, validade discriminante com medidas de VP e sensibilidade para discriminar o desempenho entre os grupos. Análise de componentes principais revelou que os testes de atualização apresentaram altas cargas e um fator separado das medidas de VP. Relações positivas, significativas, porém baixas, foram encontradas com medidas de funcionalidade. Conclusão Esses resultados fornecem bons parâmetros psicométricos para as medidas desenvolvidas, aplicáveis em contextos de pesquisa cognitiva da esquizofrenia.

Adaptive behavior refers to conceptual, social and practical skills, which allow adaptating to the environment. This study aims to do a scientific literature...

This study aims to evaluate the effectiveness of an intervention program for preschool children in an area where educational standards are poor. The participants, 129 children aged between 3 and 6 years, belonging to a public kindergarten in a Brazilian state with the second lowest human development index were involved in this research. The children were divided into an experimental intervention group and control group, where intelligence, memory, vocabulary, rapid automatized naming, and phonological awareness were evaluated before and after an intervention. The results show improvements in receptive vocabulary and rapid automatized naming in the experimental group after intervention. The level of intelligence prior to intervention was able to predict 25% of the vocabulary performance after intervention. Phonological awareness was predictive to nearly 26% of the performance in vocabulary after intervention only in the experimental group.

Studies have suggested that reading speed (RS) or fluency should be a component of reading comprehension models. There is also evidence of a relationship between RS and reading comprehension. However, some questions remain to be explored, as the changes in such a relationship may be a function of development. In addition, while there are studies published with English speakers and learners, less evidence exists in more transparent orthographies, such as Portuguese. This study investigated the relationship between reading comprehension and RS in typical readers. Objectives included elucidating the following: 1) the contribution of RS to reading comprehension controlling for intelligence, word recognition, and listening and 2) the differential relationships and contributions of RS to comprehension in different school grades. The sample of participants comprised 212 students (M = 8.76; SD = 1.06) from 2nd to 4th grade. We assessed intelligence, word recognition, word RS, listening, and reading comprehension. Performance in all tests increased as a function of grade. There were significant connections between reading comprehension and all other measures. Nonetheless, the regression analysis revealed that word RS has a unique contribution to reading comprehension after controlling for intelligence, word recognition, and listening, with a very modest but significant improvement in the explanatory power of the model. We found a significant relationship between RS and reading comprehension only for 4th grade and such relationship becomes marginal after controlling for word recognition. The findings suggest that RS could contribute to reading comprehension in Portuguese beyond the variance shared with listening and, mainly, word recognition, but such a contribution was very small. The data also reveal a differential relationship between RS and reading comprehension in different school grades; specifically, only for the 4th grade does RS begins to relate to reading comprehension. The findings add a developmental perspective to the study of reading models.

present study investigated the cognitive profiles of dyslexic adults on the Wechsler Adult Intelligence Scale (WAIS-III, Brazilian version). A total of 31 adults with dyslexia and 31 control readers who were matched by age and education level performed a phonological awareness and word reading test. They also completed the WAIS-III. The outcomes of the tests showed that dyslexics underperformed on Verbal IQ and the Picture Completion, Coding, Matrix Reasoning, Similarities, Letter-Number Sequencing, and Vocabulary subtests. No differences were found between groups in the index scores. The analysis of cognitive profiles showed that dyslexics had a lower Verbal IQ compared with Performance IQ. The index score analysis showed poorer skills in Working Memory than in Verbal Comprehension, and the best performance was observed in Perceptual Organization. These results show the importance of cognitive assessment in understanding the difficulties faced by adults with dyslexia.

The literature shows that children with autism spectrum disorders (ASD) demonstrate a heterogeneous pattern of cognitive abilities, including nonverbal abilities. However, there is a need for better cognitive characterization of this population for both research and intervention purposes. The present study aims to verify the Leiter-R performance profile for 40 children between the ages of 3 and 8 years old with ASD. The performance of the ASD children in each subtest and their total scores were compared to those of a control group of typically developing children, and intragroup analysis was conducted to verify the strengths and weaknesses of the children with ASD. The results show that individuals with ASD have difficulties with abstract reasoning related to fluid intelligence as well as selective attention and inhibition. Conversely, their visuo-spatial abilities are their strength. Cluster and comparative intra-group analyses indicate that nonverbal cognitive abilities are heterogeneous among the individuals within the ASD group. Performance in nonverbal tasks is positively correlated with adaptive functioning in communication and daily skills domains and inversely correlated with symptom severity as measured by the Autism Behavior Checklist. These results corroborate the literature associating cognition and functionality in ASD.

http://dx.doi.org/10.5902/1984686X9779A importância da avaliação de inteligência nos Transtornos do Espectro do Autismo se deve ao fato de alterações cognitivas estarem relacionadas com a severidade dos sintomas, funcionamento adaptativo, prognóstico e com o planejamento de intervenções mais eficazes. Sendo assim, o objetivo do presente estudo foi verificar a adequação do teste não-verbal de inteligência SON-R2 ½ - 7 [a] para avaliação de um grupo de crianças com TEA. Participaram 18 meninos com idades entre 4 e 7 anos, diagnosticados com base nos critérios do DSM-IV-TR e que pontuaram em instrumentos de rastreamento. Foram utilizados o teste de inteligência SON-R2 ½ - 7 [a], o Inventário de Comportamentos Autísticos (ICA), o Questionário de Comportamento e Comunicação Social (SCQ) e a Escala de Comportamento Adaptativo de Vineland (VABS). Os resultados mostraram que 55,6% do grupo obteve QI inferior à média, e houve diferença significativa entre o desempenho do grupo TEA e da amostra normativa nos quatro subtestes que compõem o instrumento. Análises intra grupo indicaram diferenças estatisticamente significativas entre os subtestes, embora tenham sido obtidas correlações positivas e significativas entre si. Correlações negativas e significativas foram observadas entre QI Total no SON-R2 ½ - 7 [a] com o ICA e o QCS; assim como foram observadas correlações positivas, significativas do QI Total com os escores obtidos na VABS. Os resultados obtidos corroboram achados prévios que indicam relações moderadasentre inteligência, severidade dos sintomas e funcionalidade, bem como a presença de perfil específico de desempenho não-verbal de crianças com TEA.

RESUMO Este estudo verificou os parâmetros psicométricos da escala não-verbal de inteligência Leiter-R. Esta foi administrada em 213 crianças com idade entre 6 e 8 anos. Análise fatorial exploratória e índices de ajustes confirmatórios mostraram adequação da estrutura interna para dois fatores conforme a versão original do instrumento. Foi verificada estabilidade temporal, com correlações de magnitude moderada a alta entre teste e re-teste. Coeficientes de Kuder-Richardson e Spearman-Brown variaram entre os subtestes em função das diferentes idades. Maiores valores foram observados nos subtestes Sequências e Padrões Repetidos para todas as idades. Aumento significativo dos escores ocorreu apenas dos 6 para os 7 e 8 anos. Foram verificadas evidências de validade convergente com a WISC-III e as Matrizes Progressivas Coloridas de Raven. ABSTRACT This study verified psychometric parameters of the Leiter-R, a nonverbal intelligence scale. The scale was administered to 213 children between 6 and 8 years. Exploratory factor analysis and confirmatory indexes showed adequacy for a two factor structure according to the original version. Moderate and high correlations between test-retest measures indicated the stability of the test scores. The values of Kuder-Richardson and Spearman-Brown coefficients varied between subtests according to the age of the children. In all age groups the highest values were observed for the subtests Sequential Order and Repeated Patterns. Significant increase in scores occurred only from 6 to 7 and 8 years. Evidence of convergent validity was obtained between the Leiter-R with the WISC-III and the Raven Colored Progressive Matrices.

Os transtornos globais do desenvolvimento (TGD) são caracterizados por anormalidades qualitativas e abrangentes em três domínios do desenvolvimento: interação social recíproca, comunicação e presença de um repertório comportamental de interesses restritos, repetitivo e estereotipado. Estudos genéticos têm identificado a recorrência de TGD numa mesma família. O presente estudo teve por objetivo rastrear a ocorrência de sinais e sintomas de TGD em irmãos de indivíduos com esse diagnóstico. Participaram do estudo 25 sujeitos provenientes de 19 famílias. A coleta de dados foi realizada mediante a utilização da versão brasileira do Autism Screening Questionnaire (ASQ), ou Questionário de Comportamento e Comunicação Social. Foram confirmados dois casos de irmãos com TGD (10,52% dos casos), sendo um irmão gêmeo monozigótico e um irmão de um probando com diagnóstico de síndrome de Asperger. Os dados apontam para taxas mais elevadas do que aquelas descritas na literatura (2-6%) e se aproximam dos achados que relatam 10% de recorrência familiar em gêmeos dizigóticos. Esse resultado fornece evidências de possíveis fatores neurogenéticos para explicar a ocorrência de TGD nos familiares dos probandos estudados e salienta a necessidade de efetuar o rastreamento desse transtorno não só na criança avaliada, mas também em seus irmãos.Pervasive developmental disorders (PDD) are characterized by comprehensive and qualitative abnormalities affecting three areas of development: reciprocal social interaction, communication, and a repetitive, stereotyped behavioral repertoire, of limited interests. Genetic studies have identified the recurrence of PDD in the same family. The present study aimed to trace the occurrence of signs and symptoms of PDD in the siblings of patients with this diagnosis. The study included 25 subjects from 19 families. Data collection was performed using the Brazilian version of the Autism Screening Questionnaire (ASQ). Two cases of PDD in siblings were confirmed (10.52% of cases): a monozygotic twin brother and the brother of a proband with a diagnosis of Asperger syndrome. Our data indicate higher rates of PDD in siblings than described in the literature (2-6%), close to the findings that suggest a 10% rate of familial recurrence in dizygotic twins. This result provides evidence of possible neurogenetic factors to explain the occurrence of PDD in relatives of the probands assessed and underscores the need to screen not only the child under evaluation, but also their siblings.
