What this trial studies

This project aims to evaluate the effectiveness of cognitive behavioral therapy for insomnia (CBT-I) in patients with treatment-resistant schizophrenia who also experience sleep disturbances. Participants will be randomly assigned to receive either CBT-I focused on sleep issues or standard cognitive behavioral therapy addressing their overall psychopathology. The study will assess changes in sleep quality, psychotic symptoms, and quality of life over a 12-week period. The primary analysis will compare the outcomes between the two groups using repeated measure ANOVA.

Why it matters

Potential benefit: If successful, this approach could significantly improve sleep quality and reduce psychotic symptoms in patients with treatment-resistant schizophrenia.

How similar studies have gone: Other studies have shown promising results using cognitive behavioral therapy for insomnia in various populations, suggesting potential success in this novel application.
