Brief Summary:
Social impairments are core features of schizophrenia that lead to poor outcome. Social skills and competence improve quality of life and protect against stress-related exacerbation of symptoms, while supporting resilience, interpersonal interactions, and social affiliation. To improve outcome, it is necessary to remediate social deficits. Existing psychosocial interventions are moderately effective but the effort-intensive nature (high burden), low adherence, and weak transfer of skills to everyday life present significant hurdles toward recovery. Thus, there is a dire need to develop effective, engaging and low-burden social interventions for people with schizophrenia that will result in better compliance rates and functional outcome.
In a previous pilot study, the investigators tested the effectiveness of a novel adaptive virtual reality (VR) intervention in improving targeted social cognitive function (social attention, as indexed by eye scanning patterns) in individuals with schizophrenia. 10 sessions of 1-hour VR intervention were sufficient to engage the target mechanism of social attention and improve negative symptoms. Acceptability and compliance were very high among the participants. In fact, improvements were seen at about 4-5 sessions. Therefore, we used 8 sessions for the R33 phase.
The next phase, supported by a R33 grant compares the VR social skills training with a control condition. This new protocol includes a control condition for the exposure to computerized training across the 8 sessions and incidental exposure to social interactions (i.e. interactions with experimenters twice a week for 4-5 weeks). The control condition consists of commercially available cognitive video games played on the same computer for the same duration as the social VR training condition. This control condition is called Cognitive training game condition.

Detailed Description:
The effectiveness of the social skills VR training at an optimal dose will be compared with an active control condition (computerized cognitive training game) in improving social attention (Social Engagement Latency: SEL), symptoms and social cogitive functioning in a pilot randomized cross-over trial.
Participants with schizophrenia will undergo a baseline assessment of social cognitive functioning, and clinical symptoms. Potential changes after Social skills VR training compared with cognitive game training will be examined.
Individuals with schizophrenia will be randomized to either the social skills VR training or the cognitive training at baseline. They will then participate in 8 sessions of social skills VR training or cognitive training (1 hour per session, twice a week for 4-5 weeks). After completion of the 8 sessions per training condition, they will cross over and participate in the other condition.
Social engagement latency (SEL) will be used as a measure of social attention which is the primary target. The Social Functional Scale (Birchwood, 1991), the the Scale for the Assessment of Negative Symptoms (SANS) and the Scale for the Assessment of Positive Symptoms (SAPS) will be used to assess social functioning and symptoms. Emotion perception will be assesed by the Bell-Lysaker Emotion Recognition Task (BLERT-A).
Matched healthy control participants will be recruited to obtain comparison data for optimal performance levels but these healthy control participants will not undergo social skills training.
Lastly, at the end of the R33 project, if this VR social skills VR training shows that it can improve social attention, which may improve social outcome in schizophrenia, it will be possible to refine the protocol to make the method more accessible, less burdensome and widely available in the future by moving towards a mobile application.
