What this trial studies

This clinical trial investigates the effectiveness of group-based treatment for Delayed Sleep-Wake Phase Disorder (DSWPD) in patients with comorbid psychiatric illnesses. Participants will receive bright light therapy at gradually advanced timings, with some also using blue-blocking glasses to enhance treatment efficacy. The study aims to assess both sleep and psychiatric symptoms through a randomized controlled trial format, leveraging an established sleep-school model at Bjørgvin District Psychiatric Hospital. Individual consultations will ensure participants meet eligibility criteria before joining the group sessions.

Who should consider this trial

Good fit: Ideal candidates are patients referred to the sleep-school who meet DSM-V criteria for DSWPD and have moderate to severe psychiatric illness.

Not a fit: Patients who work night shifts or do not meet the diagnostic criteria for DSWPD may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve sleep quality and psychiatric symptoms in patients with DSWPD.

How similar studies have performed: Previous studies have shown promising results for similar interventions in treating sleep disorders in psychiatric populations, indicating potential for success.
