ABSTRACT
Basic characteristic of Autism Spectrum Disorder (ASD) are the particularities of information processing owing to limitations over development of neural nodes between informational stimulus, while objectifiablebehaviors are resultant observable secondary consequences that people with ASD can present in greater or lesser rank and even not present it. For this reason, it´s necessary adjust the diagnostic scales to psychological principles of perceptual-cognitive processing for reduce diagnostic errors possibles of behavior test, especially when it corresponding to level-1 ASD. This research aims determine the specific level of ASD according the integrated principles, both behavior and belonging to cognitive processing. A total of 124 kids with ASD have participated. Analysis was found relating 6 dimensions, which are made up by 24 variables, relating to ASD level variable. Data found through the lineal regression analysis show that interactional and perceptual-cognitive dimensions are greatly predicitvefor the specific ASD level diagnosis. In synthesis, psychometric statistics summative means conclusive with the diagnosis to ASD level in percentiles are following: 5.77-7.88 belong to ASD level-1, between 7.88-9.01 to ASD level-2 and a score ≥ 9.02 would correspond to ASD level 3.
