Ojea (2023) has published the Precision Scale Perceptivo- Cognitive (PS-PC-ASD), with the aim of determining the diagnosis of people with autism spectrum disorder (ASD), which consists of three main weighted domains: 1) the perceptual-cognitive domain, 2) the social domain, and 3) the practical domain, in order to incorporate the measurement of cognitive neural values, which involve the level of neuropsychological and biological processing of information, from the input of information through perceptual sensory memory to semantic memory and its related episodic memory, as well as the development of interconceptual relationships that develop throughout the processes of information coding through working memory.

In this study, the PS-PC-ASD scale has been validated for a total of N: 346 participants, which is a significantly broad sample, being a highly specific group, of which 112 don’t have any specific diagnosis, 140 have a level 1 autism diagnosis, 67 have level 2, and 27 have level 3, as the International Classification of the American Psychiatric Association (APA, 2013).

The comparative data, obtained using a one-way ANOVA test, as well as the subsequent transformation of all direct scores (DS) found in the observation questionnaire into typical scores (Z), were used to construct the three categorical dimensions with typified scores: 1) processing category, 2) social category, and 3) behavioural category, whose typical sum provides a highly accurate analysis of explanatory variance, analysed using stepwise linear regression analysis, in which the three dimensions exhibit significant critical levels explaining the diagnostic data within the three categories (sig: .00).

Finally, the correspondence of the total sum of typical scores found in accordance with the corresponding percentile, in intervals of five, the 50th percentile has corresponded to the typical average sum of -1.38, from which point a diagnosis compatible with autism can be definitively considered. From this percentile onwards, an increase in intensity implies greater severity in the diagnostic group for this disorder.

In essence, the initial data found for the construction of the Scale has been corroborated, concluding that the Diagnostic Precision scale is a highly effective and positive instrument for the specific diagnostic precision of individuals with ASD.
