La información que ofrecen los maestros sobre los problemas psicológicos suele ser frecuentemente muy útil dado que éstos pueden comparar el desarrollo del niño con su grupo de iguales. Conclusions: The EDUTEA could be useful in ASD screening protocols in schools. Moderate correlations were found with the severity score of the Autism Diagnostic Observation Schedule (ADOS-2) and the child pragmatic competence. We propose using a cut-off score of 10, which gives high values of sensitivity (87%), specificity (91.2%) and positive predictive value (.87). The ROC curve showed that the area under the curve was highly predictive (.90). Results: The EDUTEA showed a two-factor structure with high internal reliability: Social communication impairments (α=.95) and Restricted behaviour patterns (α=.93). Method: It was designed according to DSM-5 criteria and validated in a sample of 2,660 Spanish schoolers. The EDUTEA questionnaire aims to provide clinicians and researchers with a brief tool that can be used to screen autism spectrum disorders and social communication disorders in school settings. Bolton and C.Teacher's reports about child psychopathology are often useful because they make it possible to compare children's development within their normative peer group.

This also showed that the CAST can be used as a screening instrument in epidemiology research and has been translated into many languages, for comparative prevalence studies. Importance: This showed that autism is far more common than was previously thought. This means that there are autistic individuals who remain undetected through the school years who may benefit from support and intervention. This study also found for the first time that for every 3 known cases of autism, there are 2 undiagnosed cases. Results: We confirmed recent studies from other prevalence studies that autism affects approximately 1% of the population. Method: We used the CAST as a screening instrument in a large population study of 20,000 primary school age children in Cambridgeshire. The CAST discriminates autistic children from typical children well, and CAST scores show strong heritability in a twin study, suggesting it is a reflection of the underlying genetic liability for the number of autistic traits a person has. The change of name reflects that it was originally designed for a prevalence study of Asperger Syndrome in childhood but is useful for screening all children who may be autistic. Aims: To determine the prevalence of autism in a UK sample.īackground: We developed the CAST, formerly known as the Childhood Asperger Screening Test but renamed as the Childhood Autism Spectrum Test.
