Detailed analysis of the Childhood Autism Spectrum Test CAST allows to differentiate clinical subtypes with difficulties in social communication
Main Article Content
Abstract
The Childhood Autism Spectrum Test-CAST (Scott et al., 2012) is a screening test for Asperger syndrome or autism spectrum disorder-grade 1 (ASD1). This study aims to analyze its different dimensions. Methodology: CAST was applied to 254 patients from the Neuropediatric Unit, aged 5 to 16 years, affected by: ASD1 (n = 17); social communication disorder (n = 43); procedural learning disorder (n = 60); attention-deficit/hyperactivity disorder (n = 44); intellectual disability (n = 30) and intellectual disability and epilepsy (n = 60). Results and discussion: with the traditional use of CAST in our clinical sample, 47.1% and 33.75% of false negatives and positives were obtained. A factor analysis of the 31 items of the questionnaire is carried out. A good fit of the data (KMO = 0.65 and MSA = 0.47-0.88), 7 factors are obtained, which explain 63% of the total variance. Reliability and validity are adequate. The discriminant analysis indicates that this new correction and interpretation allows classifying correctly 86.7% of the sample with or without difficulties in the social use of language. The most frequently altered dimensions in each clinical group are detailed. Conclusion: this analysis of CAST provides relevant information for the differential diagnosis of neurodevelopmental disorders.
