Abstract

Ojea (2023) has published a Perceptual-Behavioural Precision Scale (PS-PC-ASD) for the diagnosis of individuals with autism spectrum disorder (ASD), which are made up of three main domains weighted based on the number of items 
that each domain contains: 1) the perceptual-cognitive domain, 2) the social domain, and 3) the practical domain, in the aim of incorporating the measurement of cognitive values that involve the level of neuropsychological and biological processing of information, starting from the input of information of the sensory-perceptual memory into the semantic and episodic memory if possible, as well as the interconceptual relationships developed by the coding processes, which provide this access through working memory.

This study compared the data resulting from the ASD' diagnosis, found in accordance with the PS-PC-ASD Scale, in relation to the Autism Diagnostic Interview Revised (ADI-R) (Rutter et al., 2003), which is based mainly on the basic criteria of the currently official International Classification of the American Psychiatric Association (APA) (2013).

The main aim of this study is therefore to observe whether there're statistically significant differences in the diagnosis of people with ASD between the two Scales, the ADI-R Scale and the PS-PC-ASD Scale.

The comparative levels, found through the Wilcoxon statistical test, showed that there were significant differences in the diagnostic results of the participants, according to diagnostic Scale applied (sig: .00).

Furthermore, the Kruskal-Wallis non-parametric test found the variables of 'gender' and 'age' of the participants were interdependent for both Scales. Results didn't were shown significant differences in the variable ‘gender’ for the ADI-R Scale, non-significant critical levels were obtained (sig: .27), nor for the PS-PC-ASD Scale (sig: .81). However, when the PS-PC-ASD Scale was used, significant critical levels were observed for the variable ‘age’ (sig: .01), whereas in the ADI-R Scale, no statistically significant levels were found for ‘age’ variable (sig: .09).

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.
