![]() La versión mexicana del CARS es un instrumento válido y confiable para el diagnóstico del autismo en niños y adolescentes mexicanos. El análisis discriminante mostró que el CARS clasificó correctamente al 97% de los niños con autismo, al 70% con trastornos generalizados del desarrollo no especificados de otra manera (PDD-NOS) y al 12.5% con el síndrome de Asperger. La concordancia con el DSM-IV y el DSM-5 fue de 71% y 84.5% la sensibilidad fue de 58.1% y 46-7% y la especificidad de 76.6% y 90.5%, respectivamente. La validez convergente con el ADI-R mostró correlaciones moderadas, r s =. La validez concurrente entre el CARS y el diagnóstico según el DSM-IV con el coeficiente de correlación de Spearman fue r s =. La consistencia interna del total de ítems del CARS fue α =. Inferimos el diagnóstico según los criterios del DSM-5 seleccionando algunos reactivos sensoriales atípicos de la escala ABC. Los padres completaron el M-CHAT, el ABC, el ADI-R, y la entrevista clínica semiestructurada según criterios del DSM-IV. Los participantes (N = 137), 78.8%, fueron del sexo masculino, con un rango de edad de entre 2 y 18 años, media = 8.5. Es la herramienta más utilizada para el diagnóstico del autismo en México.Įstudiar sus propiedades psicométricas en la población Mexicana utilizando los criterios del DSM-IV y del DSM-5.Įl estudio fue observacional y transversal. La Escala de Evaluación del Autismo Infantil (CARS) es un instrumento observacional para evaluar el autismo. Keywords: Autism+ autism spectrum+ validity+ reliability+ CARS. The Mexican version of the CARS is a valid and reliable instrument for diagnosing autism in Mexican children and adolescents. The discriminant analysis showed that the CARS correctly classified 97% of children with autism, 70% with pervasive developmental disorders not otherwise specified (PDD-NOS), and 12.5% with Asperger’s syndrome. The concordance with the DSM-IV and DSM-5 was 71% and 84.5%, sensitivity was 58.1% and 46-7%, and specificity 76.6% and 90.5%, respectively. The convergent validity with the ADI-R showed moderate correlations, r s =. ![]() The concurrent validity of the CARS and the DSM-IV criteria showed a Spearman coefficient of correlation of r s =. The internal consistency for the total CARS items was α =. We inferred DSM-5 criteria by selecting atypical sensory items from the ABC. ![]() Parents completed the M-CHAT, the ABC, the ADI-R, and semi-structured clinical interviews with DSM-IV. Participants (N = 137) were 78.8% male, with an age range between 2 and 18 years, mean 8.5. This is an observational, cross-sectional study. ![]() To study the psychometric properties in the Mexican population using DSM-IV and DSM-5 criteria. It is the most widely used instrument for the diagnosis of autism in Mexico. © 2017 International Society for Autism Research, Wiley Periodicals, Inc.The Childhood Autism Rating Scale (CARS) is an observational instrument for assessing autism. © 2017 International Society for Autism Research, Wiley Periodicals, Inc.ĪSD CAST Spanish population psychometric properties. The data show that the CAST can be a valid and reliable questionnaire for ASD screening in Spanish clinical and community populations. Like previous adaptation studies, a two-factor structure was found. 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. Factorial and convergent validity is also assessed. 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). 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.
