Abstract
The perceptual-Cognitive-Behavioural
Diagnostic Precision Scale for Autism Spectrum Disorder allows to
complement the analysis of the autism diagnosis through the measurement of
variables the neuropsychological processing of human information to avoid high
errors over ASD diagnosis currently existing, derived from unilateral analysis
of the behaviour criteria component of the actual Scales. The empirical scoring
of the Scale has been verified to N= 75, being 38 participants belonging to the
TEA-1 level, 24 to TEA-2 and 13 to TEA-3, has allowed find a statistical
reliability of Cronbach's Alpha average greater to .91 in the ten dimensions of
the Scale: 1) comprehension,
2) significant, 3) categories, 4) intercategorical 5) relationships-neural-nodes,
6) semantic recovery, 7) social interaction, 8) social communication, 9)
stereotyped behaviours, and 10) restrictive behaviours. These ten dimensions have
been statistically grouped around three great categories to analysis: 1)
perceptual-cognitive processing, 2) social interaction, and 3) behaviour. The
conclusive statistical analyses indicate that perceptual-cognitive process
category explains 88.52% of total accumulated explicative variance, social
category: 10.19% and behaviour: 1.28%; which shows the importance of the
perceptual-cognitive dimensional factor analysis, in order to conclude with the
mean percentiles of the diagnostic conclusion regarding each ASD´ level,
according to International Classification of the American Psychiatric
Association DSM-5 (APA, 2023).
