“…The Kappa coefficient was 0.90. The assessment of the M-CHAT's reliability was conducted by Castro-Souza 15 using the translation proposed by Losapio and Pondé 21 , and it showed a satisfactory Cronbach's alpha (0.95) for the overall score of the 20 items of the scale. Internal consistency was lower for the ATA, being 0.71 for the overall score of its 23 items 17 .…”

Objective: To systematically review the scientific literature on the psychometric properties of international instruments for the assessment of autism spectrum disorder (ASD) in the Brazilian population. Methods: A search of bibliographic references was conducted in six electronic databases: PsycINFO, PubMed, IndexPsi, Lilacs, Capes (theses and dissertations) and SciELO. The studies were selected by two independent researchers. results: The procedure identified 11 studies of the Brazilian population that encompassed six ASD assessment tools. Given the information provided, the adaptation of the M-CHAT, a screening instrument, was the best conducted. All steps of the adaptation process were described and the changes made to the final version of the instrument were presented, which was not addressed in other studies. In terms of reliability, all of the instruments that assessed internal consistency showed adequate values. In addition, the ADI-R and the CARS adaptations also satisfactorily contemplated inter-rater reliability and test-retest indices, respectively. Finally, all studies aiming to validate instruments showed evidence of validity and sensitivity, and specificity values above 0.90 were observed in the ASQ, ADI-R and ABC. Conclusion: Considering both the psychometric aspects and the copyright information, the screening instrument that currently appears to be best indicated for clinical and research use is the M-CHAT. It was also noticed that there are still no specific ASD diagnostic tools available for use in Brazil. This lack of diagnostic instruments consists in a critical situation for the improvement of clinical practice and the development of research in this area. reSuMOObjetivo: Revisar sistematicamente a literatura científica acerca das propriedades psicomé-tricas de instrumentos internacionais para a avaliação do transtorno do espectro do autismo (TEA) na população brasileira.

Dadas as informações fornecidas, a adaptação do M-CHAT, um instrumento de rastreamento, foi a melhor realizada. Todas as etapas do processo de adaptação foram descritas e as alterações feitas para a versão final do instrumento foram apresentadas, o que não foi explicitado em outros estudos. Em termos de fidedignidade, todos os instrumentos que avaliaram a consistência interna apresentaram valores adequados. A ADI-R e a CARS também contemplaram satisfatoriamente a fidedignidade entre avaliadores e os índices de teste-reteste, respectivamente. Finalmente, todos os estudos que objetivaram a validação de instrumentos apresentaram evidências de validade e sensibilidade, e valores de especificidade acima de 0,90 foram observados no ASQ, ADI-R e...

“…Instruments developed in a different culture should therefore be translated into and adapted for the population in which they will be used 92 . According to our review, few of the published articles fell into this category, which is considered essential for scientific research: only nine articles and nine dissertations tested the psychometric properties of screening instruments such as the ASQ, CARS, and ABC [94][95][96][97][98][99][100][101] . According to a PubMed search, over 70 foreign studies published during the review period tested the validity, reliability, specificity, and sensitivity of ASD assessment instruments.…”

ABSTRACTobjectIve. This systematic review sought to conduct a general analysis of the Brazilian scientific output on autism spectrum disorders (ASD) published between 2002 and 2009. Methods. A literature search was conducted in the scientific databases PubMed, SciELO, and LILACS and in the CAPES portal, using keywords such as "autism" and "pervasive developmental disorders". results. A total of 93 articles were identified, most of which were authored by researchers from Southeast Brazil and affiliated with public universities. Approximately one-third of all articles were published in journals with an impact factor ranging from 0.441 to 3.211; most were based on small sample sizes. Furthermore, 140 theses and dissertations were identified, 82.1% of which were master's theses. Interventions for ASD were the predominant research topic. conclusIon. Brazilian researchers are clearly interested in the topic of ASD; however, a substantial portion of their scientific output is limited to doctoral dissertations or master's theses. A minority of articles was published in journals with a high impact factor. These findings suggest the need for studies with larger sample sizes, which could produce higher-impact findings and thus increase visibility of the Brazilian scientific output in the field of ASD research.

“…Na última década, aumentou no Brasil o número de pesquisas destinadas à tradução e adaptação de instrumentos para rastreamento e auxílio no diagnóstico dos TEA [27][28][29][30][31][32] . Por outro lado, estudos sobre a ocorrência familiar do transtorno são praticamente inexistentes no país, assim como são escassas as pesquisas de cunho epidemiológi-co. Dessas últimas, apenas dois estudos epidemiológicos foram divulgados até o momento 33,34 .…”

“…Assim, avaliações diagnósticas desse tipo, realizadas pelas equipes de saúde, poderiam ser ampliadas para familiares de primeiro grau. Sugere-se, para isso, o uso de instrumentos adaptados culturalmente no país [28][29][30][31][32] . Desta forma, o objetivo deste estudo foi identificar sinais e sintomas de TEA em irmãos de indivíduos previamente diagnosticados com o transtorno.…”

ResumoOs 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. Descritores: Irmãos, genética, transtornos do espectro do autismo. AbstractPervasive 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.
