Introduction: Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmentaldisorder that usually begins in childhood. Inconsistent with one’s developmental stage, thiscondition is marked by attention deficit, impulsivity, and hyperactivity. The present studyaimed to investigate the effect of virtual reality intervention (VRI) on impulsivity, sustainedattention, and divided attention in children with ADHD.Methods: This is a quasi-experimental study with a pretest-posttest control group design. Thestudy population consisted of 103 boys and girls diagnosed with ADHD seeking treatmentat Baqiyatullah Hospital in Tehran in 2021. Thirty children who met the inclusion criteriawere purposefully selected and allocated to two groups: a control group (only taking Ritalin)and an intervention group (n=15 per group). The intervention group received VRI (twelve60-minute sessions held three times weekly). The research instrument included the integratedvisual and auditory continuous performance test. Data analysis was conducted using analysisof covariance (ANCOVA).Results: The results revealed that VRI improved impulsivity, sustained attention, and dividedattention in children diagnosed with ADHD (P<0.001).Conclusion: Based on the findings, VRI can improve sustained attention, divided attention,and impulsivity in children with ADHD.
