Overview
A randomised, controlled, double-blind clinical trial will be carried out to evaluate the effectiveness of a VR assisted treatment for negative symptoms in people with schizophrenia. Patients with a standardised diagnosis of schizophrenia meeting the inclusion criteria will receive 12 weekly sessions of VR assisted therapy plus treatment as usual (TAU). A control group will be exposed to a neutral VR environment plus TAU. The hypothesis is that patients who are treated with active VR assisted therapy will have less negative symptoms as rated by the PANSS-N scale, compared to the control group.
The protocol was approved by the hospital ethics committee of the Servicio de Salud Metropolitano Suroriente. Patients sign an informed consent form, from which they may withdraw at any point during the intervention.
