Virtual Environments Using Video Capture for Social Phobia with Psychosis

摘要

A novel virtual environment (VE) system was developed and used as an adjunct to cognitive behavior therapy (CBT) with six socially anxious patients recovering from psychosis. The novel aspect of the VE system is that it uses video capture so the patients can see a life-size projection of themselves interacting with a specially scripted and digitally edited filmed environment played in real time on a screen in front of them. Within-session process outcomes (subjective units of distress and belief ratings on individual behavioral experiments), as well as patient feedback, generated the hypothesis that this type of virtual environment can potentially add value to CBT by helping patients understand the role of avoidance and safety behaviors in the maintenance of social anxiety and paranoia and by boosting their confidence to carry out “real-life” behavioral experiments.
