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. '
The next phase, supported by a R33 grant will compare the VR social skills training with a control condition. This new protocol includes a control condition for the exposure to computerized training across the 10 sessions and incidental exposure to social interactions (i.e. interactions with experimenters twice a week for 5 weeks) by including a control condition, which involves computerized brain fitness training for 10 sessions.

Schizophrenia Schizo Affective Disorder Social Skills | Behavioral: VR social skills training Behavioral: Cognitive training | Not Applicable |
The effectiveness of the social VR training (n=20) at an optimal dose will be compared with an active control condition (computerized cognitive training) (n=20) in improving social attention (social engagement latency: SEL) and social brain network in a pilot RCT.
Participants with schizophrenia will undergo a baseline assessment of cognition, social functioning, symptoms and social brain network functioning. These behavioral, clinical and neuroimaging (fMRI of social imitation task, and resting state connectivity analyses of the social brain network) methods will be used to assess changes.
Individuals with schizophrenia will be randomized to either the social skills training or the computerized cognitive training at baseline. They will then participate in 10 sessions of social skills VR training or computerized cognitive training (1 hour per session, twice a week for 5 weeks).
In addition, long-term social outcome will be assessed approxinately 2 months after the end of training with the Social Functional Scale (Birchwood, 1991) and the SANS and SAPS for clinical symptoms. For the long-term outcome assessment, no imaging or behavioral assessments will be conducted because the primary goal of the follow-up is to assess broad levels of social functioning in the real world and because there is not sufficient time within the R33 mechanism.
16 matched control participants will be recruited to obtain behavioral and neuroiaging 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 adaptive VR technology shows that it can improve social attention, which in turn improves 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.

Arm | Intervention/treatment |
---|---|
Active Comparator: VR Social Skills Training
Participants will undergo a virtual reality social skills training program for 10 sessions. Each session takes about an hour. Participants visit the lab twice a week. Therefore, the training duration is 5 weeks.
|
Behavioral: VR social skills training
Social skills game that we developed in the R21 phase will be used across 10 sessions of training in the lab. Each session is about 1 hour long. Participants come to the lab twice a week for 5 weeks.
|
Cognitive training game
If there is a significant improvement in social skills for the active treatment condition, the reason might be that the participants were exposed to social environment by coming to the lab and interacting with the research staff twice a week for 5 weeks and/or they used a computerized training tool twice a week for 5 weeks. In order to control for these potential confounds, we included a cognitive training arm. Participants will undergo a commercially available brain fitness program (Posit Science) for ten 1-hour sessions (twice a week for 5 weeks).
|
Behavioral: Cognitive training
Commercially available brain fitness training program will be used to control for the time spent in the lab and associated social interactions as well as the total exposure to computerized games.
|
No Intervention: Healthy Controls
Healthy controls are recruited to yield comparison data. They do not undergo training.
|
SANS is a 25-item clinical symptom rating scale. It consists subscales of alogia, affective blunting, avolition-apathy, anhedonia-asociality, and attentional impairment. (Andreasen, 1983). Each subscale has a single item global score for overall severity of each symptom domain. Each item is rated for severity from least (0) to most severe (5).

SAPS has 34-items that evaluate hallucinations, delusions, formal thought disorder and bizarre behavior (Andreasen, 1984). Each subscale has a single global score item to rate the overall severity of each symptom domain.
