Continuous performance tasks (CPT) are popular in the diagnostic process of attention deficit hyperactivity disorder (ADHD), providing an objective measure of attention for a disorder with otherwise subjective criteria.
The study aimed to: 1) examine whether the VR-CPT is sensitive to methylphenidate (MPH); 2) assess how the virtual reality (VR) environment is experienced.
Twenty boys, 9-17 years, with ADHD underwent 3 CPTs: VR-CPT, the same CPT without VR (no VR-CPT) and the Test of Variables of Attention (T.O.V.A.). Subsequently, those with ADHD repeated the tests 1 hour following MPH ingestion. Immediately following the CPT, the subjects described their subjective experiences on the Short Feedback Questionnaire. Results were analyzed using ANOVA with repeated measures.
MPH reduced the omission and commission errors on all tests to a similar degree. Subjective feelings of enjoyment were most positive for VR-CPT.
The VR-CPT is a sensitive and user-friendly assessment tool for evaluating the effectiveness of MPH treatment in boys with ADHD.
持续性操作任务（CPT）在注意力缺陷多动障碍（ADHD）的诊断过程中很常用，为这种诊断标准较为主观的疾病提供了一种客观的注意力测量方法。
本研究旨在：1）检验虚拟现实持续性操作任务（VR-CPT）对哌甲酯（MPH）是否敏感；2）评估虚拟现实（VR）环境的体验情况。
20名9至17岁患有ADHD的男孩接受了3项CPT测试：VR-CPT、无VR的相同CPT测试（非VR-CPT）以及注意力变量测试（T.O.V.A.）。随后，患有ADHD的男孩在摄入MPH 1小时后重复进行测试。在CPT测试结束后，受试者立即在简短反馈问卷上描述他们的主观体验。使用重复测量方差分析对结果进行分析。
MPH在所有测试中均以相似程度减少了遗漏和错误。VR-CPT的主观愉悦感最为积极。
VR-CPT是一种敏感且用户友好的评估工具，可用于评估MPH治疗对患有ADHD男孩的有效性。
