What this trial studies

This project aims to evaluate the effectiveness of two innovative psychosocial interventions, Cognitive Enhancement Therapy (CET) and Enriched Supportive Therapy (EST), for treating persistent negative symptoms in individuals with schizophrenia. A total of 90 outpatients aged 18-60 with moderate-to-severe negative symptoms will be randomly assigned to receive either CET or EST over an 18-month period. The study will collect extensive data on symptoms, cognition, and functional outcomes at baseline and every six months to assess the efficacy of these therapies and their long-term effects.

Who should consider this trial

Good fit: Ideal candidates are outpatients aged 18-60 with a diagnosis of schizophrenia or schizoaffective disorder and persistent negative symptoms lasting at least three months.

Not a fit: Patients with acute exacerbations of schizophrenia or those with severe cognitive impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly improve the quality of life for patients with schizophrenia by reducing negative symptoms and enhancing cognitive function.

How similar studies have performed: Previous studies have shown promise in using psychosocial interventions for schizophrenia, suggesting potential success for this approach.
