Summary of the limitations in the current literature on virtual reality (VR)–based psychosocial interventions for individuals with psychosis and recommendations for future research.

Limitations in the current literature	Recommendations for future research	Impact of recommendation for future research
Limited number of studies comparing VR-based psychosocial interventions to traditional psychosocial interventions.	Perform RCTsa that compare a VR-based intervention to traditional psychosocial intervention.	Efficacy of VR-based interventions could be compared with traditional psychosocial interventions for improving cognitive, social, and vocational skills as well as auditory verbal hallucinations or paranoia.
No studies included a VR control condition.	Perform RCTs that compare a VR experimental intervention to a VR control condition.	Isolate the impact of the intervention in VR vs the effects of using VR recreationally.
Inconsistency in the number and duration of VR-based sessions across studies.	Including various numbers and durations of VR-based sessions.	Determine the optimal number and duration of VR sessions to impact rehabilitation outcomes.
Sample sizes of the included studies were relatively small.	Use larger sample sizes.	More accurate results on the impact of VR-based interventions for individuals with psychosis.
Limited number of studies featuring follow-up assessments of the skills gained during the VR intervention.	Perform follow-up assessments.	Ensure that skills gained during the VR-based interventions are maintained and transferred into the real world.
