About this study

Official title: A Circadian Medicine Light-based Intervention for Obsessive-compulsive Disorder (OCD)

The purpose of this study is to examine the effect of a light-based circadian treatment on OCD symptoms in adults with OCD and late bedtimes. This study will have important implications for understanding the role of circadian rhythms in the etiology and treatment of OCD.

Read the detailed description

Prior to the start of this study, there are screening procedures to ensure participants meet the criteria for the study. At the first consent screening appointment, participants will learn more about the study and answer questionnaires. All of the results of the screening procedures are confidential and will only be used by the study staff to determine eligibility for the study.

This study is 5 weeks long and involves 4 in-person lab visits at the Sleep and Chronobiology Lab. Participants will be randomly assigned to either an active or placebo light therapy treatment condition. Visit 1 will involve additional screening to determine eligibility, including questionnaires and interviews. If eligible, participants will then track their sleep for 2 weeks at home with a wrist-worn activity monitor and a sleep diary. Visit 2 will take place in the lab from 5:30pm until 1 hour after participants typical bedtime. The investigators will ask participants to provide saliva samples hourly to measure melatonin and complete questionnaires. The investigators will provide treatment instructions at this visit. Investigators will then ask participants to engage in the treatment at home for 3 weeks. Investigators will schedule 1 in-person visit (Visit 3) and 1 phone call to assess adherence to the treatment during these 3 weeks. Visit 4 will take place in the lab after the treatment is finished. Visit 4 will last from 5:30pm until 1.5 hours after participants typical bedtime and will involve hourly saliva samples to measure melatonin, questionnaires, and interviews.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Obsessive-Compulsive Inventory-Revised score (time frame: 3 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
