The diagnostic accuracy of Wisconsin Card Sorting Test–the Short Computerized Version (WCST-64:CV2) for children with Autism Spectrum Disorder

This study aimed to evaluate the diagnostic accuracy of Wisconsin Card Sorting Test–The Short Computerized Version (WCST-64:CV2) for children with Autism Spectrum Disorder (ASD), and differences based on gender (males and females) and classification (typically developing-TD and with ASD). The sample consisted of (<i>N</i> = 96) TD and (<i>N</i> = 48) ASD, Saudi children (aged 7–9 years). The diagnostic accuracy results showed that most (WCST-64:CV2) indicators have discrimination ability between TD and ASD children, for males and females. Accuracy differences based on gender were on three indicators (3, 4 &amp; 5). There were no significant differences (<i>p</i> &gt;.05) on indicators based on gender, however, there were significant differences (<i>p</i> &lt; .01) based on classification on all indicators, except indicators (3 &amp; 4). Interaction between gender and classification was significant (<i>p</i> &lt; .05) for one indicator (5). It is recommended to use (WCST-64:CV2) to diagnose ASD children (7–9 years), based on eight indicators for males (1, 2, 3, 4, 6, 7, 8, &amp; 9) and seven indicators for females (1, 2, 5, 6, 7, 8, &amp; 9), and to take differences based on gender and classification into account, when using (WCST-64:CV2). The (WCST-64:CV2) could be relied on for clinical/neuropsychological assessment of ASD children.
