The aim of this study was to investigate the effectiveness of using a virtual reality (VR) continuous performance test (CPT) (i.e., Nesplora Aula) to evaluate various aspects of attention and executive functioning, compared to current assessment tools and diagnostic criteria. The study assessed the validity and reliability of the VR CPT in measuring attentional abilities, and examined whether VR CPT can provide complementary/supplementary information to existing assessment methods. Data was collected from children aged 6-16 with a known or suspected diagnosis of Attention-Deficit/Hyperactivity Disorder (ADHD). In addition to the VR CPT, the battery included standard measures of attention and executive functioning, general cognitive function, and comprehensive corroborating reports completed by their families. Domain correlations were then conducted to determine the convergent and construct validity. Data was also correlated with general functioning domains to attempt to replicate past studies. The study found that results demonstrated moderate-to-strong convergent validity, suggesting acceptable construct validity for VR CPT. Overall, the results were consistent enough to support the concept. Furthermore, post-hoc tests explored convergent and construct validity for each subtype of ADHD, including combined, primarily inattentive, and primarily hyperactive-impulsive. In conclusion, VR CPT (Nesplora Aula) remains a viable tool for assessing ADHD symptoms, particularly in the hyperactive-impulsive subtype. Our findings support the use of VR technology in neuropsychological assessment, as it shows moderate to strong convergent validity with established assessment tools. However, further research is needed to fully evaluate the practicality of using VR CPT as a stand-alone diagnostic tool.
