What this trial studies

This clinical trial aims to evaluate the effectiveness of light therapy in reducing symptoms of obsessive-compulsive disorder (OCD) in young adults who have late bedtimes. Participants will wear light therapy glasses for one hour each morning over a five-week period and track their sleep patterns using a wearable monitor and electronic diary. The study will also assess the impact of different doses of light therapy on symptom reduction and circadian rhythm adjustments. Self-report measures of OCD symptoms will be collected multiple times throughout the study to gauge changes in severity.

Who should consider this trial

Good fit: Ideal candidates for this study are young adults aged 18-35 with a primary diagnosis of OCD and late bedtimes of 1am or later.

Not a fit: Patients who are currently participating in other research studies or have certain medical conditions or lifestyle factors may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a novel, non-invasive treatment option for young adults suffering from OCD.

How similar studies have performed: While light therapy has been explored for various conditions, this specific application for OCD in young adults is relatively novel and has not been extensively tested.
