About this study

The proposed study aims to establish the feasibility of light therapy for postpartum depression delivered via Re-Timer, demonstrate its preliminary efficacy, and illuminate relationships between circadian shifts and mood changes using a novel, home-based circadian biomarker assessment paradigm (salivary dim light melatonin onset; DLMO).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline Score of the Hamilton Depression Rating Scale-Seasonal Affective Version (SIGH-SAD) at 5 Weeks

    Clinician-rated depression symptom severity measure; Hamilton Depression Rating Scale-Seasonal Affective Version (SIGH-SAD) (29 item version) measures depressive symptoms on a continuous scale. Higher scores indicate worse outcomes. Scores can range from 0 -73, where 0 means no depression, and 73 is the greatest possible depression. Generally scores of 20 or higher represent clinical depression

    Measured: After five weeks of light therapy

  2. Change From Baseline Score of the Edinburgh Postnatal Depression Scale (EPDS) at 5 Weeks

    Self-report of depression symptoms. The Edinburgh Postnatal Depression scale is scored from 0 to 30 where 0 is no depression and 30 is most severe depression.

    Measured: After five weeks of light therapy

  3. Change From Baseline Time of Dim Light Melatonin Onset (DLMO) at 5 Weeks

    Onset of melatonin in dim light conditions as measured in saliva (also called DLMO) Time of DLMO is measured in clock time, so a positive number in change would represent a later onset of melatonin and a negative number represents an earlier onset of melatonin

    Measured: After five weeks of light therapy

Questions about this trial

What is this clinical trial studying?

A study testing Light therapy in people with Depression, Postpartum, run by University of Michigan at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 22 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Dec 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change From Baseline Score of the Hamilton Depression Rating Scale-Seasonal Affective Version (SIGH-SAD) at 5 Weeks (time frame: After five weeks of light therapy). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02769858, which also lists 1 linked publication.

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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Apr 2021.
