About this study

Official title: Light and Negative Ion Treatment for Chronic Depression

This study investigates the potential efficacy of two nonpharmacologic treatments for nonseasonal depression, bright light exposure or high-density negative air ion exposure. Treatments are self-administered at home by the patient under close clinical supervision.

Read the detailed description

Bright light exposure and high-density negative ion exposure have been designed to mimic outdoor environmental conditions and are effective in relieving symptoms of seasonal (winter) depression, but their effectiveness in treating chronic depression has not been explored.

Participants in this 10-week study will have an interview, a complete physical exam, and six one-hour appointments for progress evaluations. They will be randomly assigned to either light or high- or low-dose negative ions. Each treatment must be taken consistently for five weeks at the same time every day, after which treatment is temporarily suspended to determine whether symptoms return. Participants will then have the opportunity to try the alternate active treatment to determine which works best for them. On two occasions, participants will provide saliva samples, used to determine the level of melatonin, a hormone that becomes active at night and indicates whether a person's internal circadian clock is "in sync" with the day-night cycle or is early or late. This diagnostic test for melatonin, which is not yet readily available in medical practice, provides our research participants with unique information that can be used to optimize the timing of future treatment.

Questions about this trial

What is this clinical trial studying?

A study testing Bright light box, High-output negative ion generator and Low-output negative ion generator in people with Mood Disorders and Depressive Disorders, run by New York State Psychiatric Institute at 2 sites 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 2 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. Some participants in this study may receive a placebo. 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?

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?

Depression scale score (time frame: 5 weeks). 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 NCT00006172, which also lists 2 linked publications.

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 1 Oct 2014.
