Currently, diagnostic assessment tools for individuals with
ASD, even those that have been empirically validated, are based on the analysis
of social and behavioural criteria. However, scientific research in the area of
ASD has progressed significantly in developing hypotheses about
perceptual-cognitive functioning, which involves highly specific
psycho-neurological information processing. These factors, which are so
important for understanding how people with ASD interact with the world, are
not sufficiently operationalised for the assessment of the disorder in current
assessment scales and tests, which can give rise to significant errors in the
ASD diagnostic process. For this reason, a Perceptual-Cognitive-Behavioural
Integration Scale (PS-PC-ASD-R) was developed for the diagnostic assessment of
individuals with ASD. It systematically
integrates social and behavioural variables with factors that form part of the
particular mode of perceptual-cognitive processing of individuals with ASD from
the initial reception of the stimulus, source memory, the creation of neural
relationships or nodes to encoding information by working memory, access to
information in semantic and episodic memory, and the processes of retrieving
encoded content according to the exigencies of the context. The PS-PC-ASD-R has
been empirically validated through various specific quantitative experimental
analyses throughout the study. The sample comprised a total of 346
participants, with and without an ASD diagnosis, corresponding to the three
levels of intensity (APA, 2013), with a highly reliable level found in the
Cronbach's alpha reliability analysis, which is significantly high (a = .91),
which can be inferred to indicate a high degree of statistical reliability in
the study. The fundamental data that shaped the ASD diagnostic process are
indicated, as the direct scores from the observation dimensions (DS) are
transformed into their corresponding typical-score to continue the rest of the
study (ZS), which finally located each ZS for each participant within the
corresponding percentile (P), concluding the ASD diagnostic process.
Finally, located each ZS total for each participant within
the corresponding percentile (P), concluding the ASD' diagnostic process,
concluding, mild ASD (level 1) ranges between the 50th-55th and 65th
percentiles, which increases significantly to moderate intensity (level 2)
between the 70th and 80th percentiles, and finally, the equivalent score for
severe ASD ranges between the 85th and 100th percentiles.
