In this validation study, the CAST was distributed to 1925 children aged 5-11 in. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. The Childhood Asperger Syndrome Test (CAST) is a parental questionnaire to screen for autism spectrum conditions. The Childhood Autism Spectrum Test (CAST Scott, Baron-Cohen, Bolton & Brayne, 2002) has proved to be a good test for screening autism spectrum disorders (ASD) and social communication problems. ASD can be hard to diagnose, and screening may not find milder cases in early childhood. It helps find out which children need more testing to see if they have ASD. © 2017 International Society for Autism Research, Wiley Periodicals, Inc.ĪSD CAST Spanish population psychometric properties. Autism spectrum disorder screening is most often used to check for signs of autism spectrum disorder (ASD) in children age 2 and under. The data show that the CAST can be a valid and reliable questionnaire for ASD screening in Spanish clinical and community populations. All age groups (toddlers / children / adults) The questions were developed by recognised experts. The quiz presented is not a scientific - diagnostic test. Like previous adaptation studies, a two-factor structure was found. Our autism spectrum test determines the initial presence of elements of autism spectrum disorder. Correlations were high between the Spanish full and reduced versions of the CAST, and ADI-R (Autism Diagnostic Interview Revised) and ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition). Some items showed low discriminating power and these results led us to propose a reduced version with 28 items and a cut-off score of 13, which presented a high sensitivity (85.7%) and specificity (91.16%), a PPV of. The full Spanish version with a cut-off score of 15 presented a high sensitivity (83.9%) and specificity (92.5%), a positive predictive value (PPV) of. However, free online tests and quizzes such as this one are solely first glances and cannot provide an accurate assessment of. Factorial and convergent validity is also assessed. The Autism Spectrum Test is based on a famous and well-regarded inventory for the assessment of the clinical concept of autism spectrum disorders, which is regarded as a range of interlinked neurodevelopmental disorders. The diagnostic agreement was 92.7, but with a fair Kappa value (0.247). This study provides evidence on its psychometric properties, describe its validity for screening and provides data on its discriminative capabilities in a Spanish sample of 4-12 year-old children from community and clinical settings (N = 1460 and 36, respectively). This study aimed to compare symptoms of autism spectrum disorder using the Childhood Autism Rating Scale (CARS) and the Social Responsiveness Scale (SRS-2) and to investigate their influencing factors. The Childhood Autism Spectrum Test (CAST Scott, Baron-Cohen, Bolton & Brayne, 2002) has proved to be a good test for screening autism spectrum disorders (ASD) and social communication problems.
