Aims of the study were to: (1) compare the performance of children with ADHD on a CPT embedded within a virtual reality classroom (VR-CPT) to the currently used Test of Variables of Attention (TOVA) CPT, and (2) assess how the VR environment is experienced. Methods: Thirty-seven boys, 9 to 17 years, with (n = 20) and without ADHD (n = 17) underwent 3 CPT’s: VR-CPT, the same CPT without VR (No VR-CPT) and the TOVA. Immediately following CPT, subjects described their subjective experiences on the Short Feedback Questionnaire. Results were analyzed using analysis of variance with repeated measures. Results: Children with ADHD performed poorer on all CPT’s. The VR-CPT showed similar effect sizes to the TOVA. Subjective feelings of enjoyment were most positive for VR-CPT. Conclusion: The VR-CPT is a sensitive and user-friendly assessment tool to aid diagnosis in ADHD. © 2009 Lippincott Williams & Wilkins, Inc.
