ENGAGE: Virtual Reality-based Psychotherapy for Negative Symptoms in Schizophrenia

The primary goal of this pilot study is to examine the feasibility and acceptability of a new Virtual Reality-based intervention against negative symptoms in schizophrenia spectrum disorders (SSD). The main questions it aims to answer are: 1. Is Virtual Reality-based therapy a feasible and acceptable treatment for negative symptoms in SSD? 2. Are there indications that the treatment is effective in reducing negative symptoms, improving daily functioning, and enhancing quality of life? Researchers will compare the new Virtual Reality-based treatment to standard psychiatric care to evaluate therapy effectiveness. Participants will be allocated to receive either 10 sessions of Virtual Reality-based therapy or Treatment as usual. All participants will undergo a thorough assessment at baseline and at follow-up after 12 weeks.
