Virtual reality (VR) offers a novel approach for psychological treatment of serious mental illness (SMI). Through a headset that renders 3D images on a screen, users are fully immersed in a virtual world that looks and feels very real. By simulating clinically relevant scenarios in highly controlled virtual environments, mental health professionals can observe and guide individuals to learn and adapt to relevant situations in real time, under safe supervision. This webinar will provide an overview of VR treatments for a range of SMIs with a focus on psychosis and anxiety-based conditions. Topics will include a background and history of VR treatments, current findings from high quality randomized controlled trials across clinical conditions, practical examples of VR treatments using case studies, as well as implementation and clinical issues including common side effects.
