Bright Light: A Novel Treatment for Anxiety
NCT01064700 · View on ClinicalTrials.gov ↗
Study Summary
The primary aim of this research was to examine the influence of bright light on anxiety in high-anxious young adults. In an acute exposure study, participants were randomly assigned to 45 min of either (1) bright light (3,000 lux) or (2) a placebo inactivated negative ion generator. Treatments were initiated ≤1 hr after awakening. At 10 min before and 30 min after the treatments, state anxiety, mood, and blood pressure were assessed. Following the acute exposure study, participants performed a 5-week study. Following a a 1-week baseline, participants were randomly assigned to four weeks of daily exposure to either (1) bright light (45 min/day; 3,000 lux) or (2) placebo inactivated negative ion generator, which were initiated ≤1 hr after awakening. Before and after the experiment, clinical ratings were conducted with the Hamilton Anxiety Scale, the Hamilton Depression Scale, and the Clinical Global Impressions scale (CGI). Following baseline, and following each week of treatment, blood pressure, as well as questionnaires for state anxiety, depression, mood, sleep, and side effects were assessed.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01064700
The ClinicalTrials.gov registry entry for NCT01064700 describes a study currently listed as completed. It is categorized as Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 33 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of South Carolina, which has 88 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Depression appearing as the primary indexed condition, and to 2 interventions — of which Litebook Bright Light Box is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01064700 reports 1 study location spanning 1 distinct geographic area — top geographies include South Carolina. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
