What this trial studies

This study evaluates the safety and efficacy of AVATAR therapy, a virtual reality-based intervention designed to reduce the intensity and frequency of auditory hallucinations in patients with schizophrenia spectrum disorder. Over a 12-week period, participants will undergo seven individual therapy sessions lasting 50 minutes each, guided by a trained psychotherapist following a strict protocol. The study will enroll 30 patients from three clinical sites located in Hungary, Spain, and Poland, and will compare outcomes against a waiting list control group.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older diagnosed with schizophrenia spectrum disorder who experience auditory hallucinations and are stable on their medication.

Not a fit: Patients who may not benefit include those with severe visual impairments, significant cognitive disabilities, or those who are averse to virtual reality technology.

Why it matters

Potential benefit: If successful, this therapy could significantly improve the quality of life for patients experiencing persistent auditory hallucinations despite medication.

How similar studies have performed: While the use of virtual reality in therapeutic settings is gaining traction, this specific approach to AVATAR therapy for auditory hallucinations is relatively novel and has not been extensively tested in prior studies.
