Objective: The virtual classroom (VC) is a head-mounted display immersive system for the assessment of attention. A meta-analysis was performed to examine the use of the VC to assess attention in children and adolescents. Method: We conducted a systematic literature search to select articles up to December 2017. Results: Thirteen studies using the VC to assess attention were included. Studies reporting comparisons between patients with various clinical conditions and healthy controls were included in the meta-analysis. The meta-analysis results revealed significant differences between groups for the percentage of identified targets (nine studies; total combined N = 431), for commission errors, and reaction time (eight studies; total combined N = 399) in favor of the nonclinical group. Conclusion: Preliminary evidence establishes the validity of the VC and suggests that this task has the potential to serve as a useful and enjoyable ecological assessment tool for the diagnosis of attention deficits in children and adolescents.
