Brief Summary

The primary aim of this study is to evaluate the safety and efficacy of AVATAR therapy, developed to address residual auditory hallucinations persisting despite medication in schizophrenia spectrum disorder. The intervention aims to reduce the intensity and frequency of these symptoms, as well as alleviate associated depressive and anxiety symptoms, using a virtual reality (VR)-assisted intervention developed for this purpose by the Danish company HEKA VR. The study will be a pre-post non-invasive, waiting list-controlled study, enrolling 30 patients from three clinical sites (Hungary, Spain, Poland). The study centers around administering therapy based on VR over a 12-week period, comprising a total of 7 sessions. These sessions are conducted individually and last 50 minutes each. The psychotherapist leading the sessions adheres to a strict protocol defined by the method's developers. During the intervention, VR technology is used to simulate the source of distressing auditory hallucinations. The therapist facilitates coping with these experiences externalized in this way through simulated conversations, supporting the development of more adaptive responses. Patients undergo a comprehensive cross-sectional evaluation of their condition before and after the intervention, including assessments of symptom severity, quality of life, and their experience with the method. The intervention is conducted with constant monitoring for possible adverse effects.
