Portuguese abstract O objetivo deste estudo é descrever como a Childhood Autism Rating Scale (CARS) se comporta em relação à Autism Diagnostic Observation Schedule (ADOS) e ao diagnóstico clínico baseado nos critérios definidos pelo Manual Diagnóstico e estatístico dos Transtornos Mentais (DSM-IV - 4ª Edição) do em crianças filhas de imigrantes. Foram avaliadas 49 crianças cujos pais imigraram para o Canadá. Nessa amostra os resultados das avaliações pelo ADOS e DSM-IV foram totalmente concordantes. Usando o ponto-de-corte padrão de 30, a CARS mostrou elevada especificidade e baixa sensibilidade. Esse estudo propõe um ponto de corte para a CARS que possa incluir o transtorno invasivo do desenvolvimento não especificado. A redução do ponto de corte para 20/21 aumentou a especificidade do instrumento para esse grupo de crianças, sem reduzir significativamente a sensibilidade.
English abstract The objective of this study was to describe how the Childhood Autism Rating Scale (CARS) behaves in relation to the Autism Diagnostic Observation Schedule (ADOS) and to clinical diagnosis based on the criteria defined in the Diagnostic and Statistical Manual of Mental Disorders, 4 th Edition (DSM-IV) for children of immigrant parents. Forty-nine children of parents who had immigrated to Canada were evaluated. In this sample, the ADOS and the DSM-IV showed complete agreement. Using the standard cut-off point of 30, the CARS showed high specificity and poor sensitivity. The study proposes a cut-off point for the CARS that would include pervasive developmental disorder – not otherwise specified (PDD-NOS). Reducing the cut-off point to 20/21 increased the specificity of the instrument for this group of children without significantly reducing its sensitivity.
