Interrelations between Perceptive-Cognitive Factors and Behavioural Variables to Level Diagnosis of People with Autism Spectrum Disorder

Abstract

Relationships analysis between perceptual-cognitive factors and behavioural variables it makes up autism spectrum disorder (ASD) differential specific diagnosis, constitute a fundamental recurrent of currently research, then found data allow the construction of integrated evaluation scales to validate more complete and reliable diagnosis of people with ASD. The interdimensional diagnostic Scale has been applied and coded for 10 dimensions: 1) conceptual units, 2) signifiers, 3) hierarchy, 4) nodal relationships, 5) categorical relationships, 6) Recovery, 7) social interaction, 8) social communication, 9) stereotypical behaviours, and 10) restrictive behaviours. A total of 75 participants with ASD have participated in this study of three ASD´ intensity levels and different age intervals, from 3 years old. Data analyses focused along study the factorial analysis determinant (KMO and Bartlett's test) statistic, as well as, bivariate correlations analysis for three dimensions calculated statistically: "processing", "social" and "behaviours", show significant critical inter-relational levels (sig: .00), which allows conclude to existence of highly relationships between both variables group and their practical applications for consequent, reliable and valid diagnosis process. Finally, the statistical data of your application to perform the level diagnostic analysis is completed, through corresponding statistical percentage, means and standard deviations, to facilitate the ASD level 1-2-3 diagnostic way.
