Virtual Reality Training for Social Skills in Schizophrenia

Study 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, we must 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. The investigators will test 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. VR technology offers a flexible alternative to conventional therapies, with several advantages, including a simplified and low-stress social interaction environment with targeted opportunities to simulate, exercise and reinforce basic elements of social skills in a very wide range of realistic scenarios, and to repeat exposure to naturalistic situations from multiple angles.

Primary Outcome

Social Engagement Latency (SEL), defined as the time taken to select an avatar by fixating eye gaze at the chosen avatar's face to initiate a new social 'mission'. This is an ecologically valid index that corresponds to one's readiness to initiate a social interaction. To start a social 'mission', the participant must choose an avatar by fixating on a semi-transparent green patch that covers the avatar's face. When the participant fixates on the avatar's face, the green patch disappears to reve
