Samenvatting

Abstract (The content of this research paper is written in Dutch)
The development of the Dutch and second version of the Alloway Working Memory Assessment (AWMA-2-NL) demands analysis of the validity and reliability to the extent of integrating the assessment as a standard neuropsychological tool for screening of the working memory functioning. The verification of validity and reliability for a psychological instrument is a necessity prior to applying the instrument in clinical practice. Especially when a clinical practitioner encounters certain patients with divergent psychological dysfunctions, such as an autism spectrum disorder (ASD), the application of an instrument is a delicate task. The verified validity and reliability of the instrument will assure the professional that he/she is working with a proper method to measure the construct, which the professional wishes to measure. The state of functioning of the working memory in children and adolescents with an autism spectrum disorder (ASD) diagnosis is point of discussion. The current neuropsychological literature seems to point in different directions, which makes it hard to interpret the literature in an unambiguous fashion. To intensify the confusion surrounding the connection between ASD and working memory models, recent research indicates that working memory has a major connection with the construct of intelligence, which also is closely related to the differential diagnosis within the group of ASD pathologies (such as Asperger’s Syndrome, Pervasive Developmental Disorder – Not Otherwise Specified [PDD-NOS] and Rett’s Syndrome).   
The results of this research indicate medium to high correlations between the individual sub-categories specified within the AWMA-2-NL, which points towards a certain degree of overlap between the individually defined constructs. In measuring a construct such as working memory a certain degree of overlap between different constructs is to be expected. One could interpret the medium to high correlations found between the different constructs within the AWMA-2-NL as a necessity to successfully measure the construct of working memory. It does however raise the question as to what degree of overlap is acceptable. When overlap is large enough, a point of discussion could be if the separate tasks actually measure distinct constructs rather than measuring two constructs that are actually the same. However, these findings remain to be a point of discussion and cannot offer evidence towards nor against construct validity in the AWMA-2-NL.
Comparison of performance between children with and without ASD, show significant differences. Compared to their non-ASD peers, children with ASD show to perform significantly worse in tasks related to verbal working memory, where as performance in tasks regarding visuospatial working memory is relatively equal. Even though these findings defy evidence found in recent research papers, the distinctions in performance does show the AWMA-2-NL’s ability to differentiate between two separate groups of children. According to COTAN this ability to differentiate can be seen as evidence towards construct validity of the AWMA-2-NL. In conclusion, the evidence found in regards to construct validity of the AWMA-2-NL is moderately positive yet insufficient: further research is necessary to fully cover the process of validation of the AWMA-2-NL.
