| Sumario: | BackgroundThe aim of this study was to test the usefulness of the Cognitive and Language scales Bayley-III in the early assessment of cognitive and language functions in the context of an autism spectrum disorder (ASD) diagnosis. This paper focuses on the application of the Bayley-III and studies the predictive value of the test result in children with ASD with different levels of verbal ability. MethodA sample of 135 children (121 boys, 14 girls) with a confirmed ASD diagnosis at age 4years were assessed with the Bayley-III before 42months of age (m=36.49, s=4.46) and later with other rating scales of different psychological and psycholinguistic functions as part of a longitudinal study [McCarthy Scales of Children's Abilities (MSCA) (n=48, 90% boys), Kaufman Assessment Battery for Children (K-ABC) (n=38, 87% boys) or Illinois Test of Psycholinguistic Abilities (ITPA) (n=44, 89% boys)]. Age assessment in months: MSCA (m=48.80, s=3.33), K-ABC (m=51.80, s=7.17) and ITPA (m=54.48, s=3.34). ResultsLower scores on the cognitive and language Bayley-III scales before 3.5years of age predicted lower cognitive and oral language levels at 4years of age. A significant correlation was found between the Cognitive Bayley-III Scale and the General Cognitive MSCA Scale, and with the Compound K-ABC Mental Processing. An association between the nonverbal cognitive level and oral language level acquired at 4years of age was found. ConclusionsThe Bayley-III is a useful instrument in cognitive and language assessment of ASD. |
