ABSTRACT
Introduction: the Childhood Autism Rating Scale is a behavioral scale considered as a detection tool to be applied in children older than 2 years, in more specialized tests, and it is also useful in autistic spectrum disorder cases as a diagnostic tool, but it seems more suitable for the evaluation of patients with low cognitive performance.Objective: to identify the advantages of the Childhood Autism Rating Scale for the evaluation of patients with autistic spectrum disorder of low and high cognitive performance.
Methods: a cross-sectional study was conducted in 20 patients aged 7 to 15 years, who were classified according to their scores in Weschler Intelligence Scale for Children-Third Edition (WISC-III): 12 had high performance index (total intelligence quotient equal to or higher than 80) and 8 children with low performance index (total intelligence quotient below 80).
Results: of 20 patients with the autistic spectrum disorder (18 children, mean age of 10.05 years), the total mean score in the Childhood Autism Rating Scale was similar between the groups (high and low performance), that is, 34.8 (± 2.3 SD) and 35.6 (± 2.6 SD) respectively. The comparisons with the Mann-Whitney´s test did not show statistically significant differences between the groups in any of the items; additionally, there were no statistically significant differences between the two groups neither in the false belief task performance nor in the total intelligence quotient and the total value of CARS in the linear regression analysis.
Conclusions: the Childhood Autism Rating Scale seems to be useful for the diagnosis and evaluation of the severity of the autistic spectrum disorder regardless of the individual´s cognitive performance.
