enhancing social skills in schizophrenia spectrum disorders - oxytocin as add-on to psychosocial treatment

Conditions: Schizophrenia Spectrum Disorders (SSD)

Summary: research on schizophrenia spectrum disorders (ssd) patients with social impairment is essential for improving treatment, enhancing the lives of affected individuals, reducing stigma, and advancing our understanding of this complex psychiatric disorder. a clinical trial focusing on the improvement of social skills in ssd has the potential to transform clinical practice and support systems to better meet the needs of those living with ssd. because of the role of oxytocin in regulating social behaviors and emotions, the investigator hypothesizes that it is beneficial in addressing the social cognition deficits observed in ssd when combined with psychosocial interventions.
