- Registration Number
- NCT07111390
- Lead Sponsor
- NYU Langone Health
- Brief Summary
This pilot study evaluates the feasibility, safety, and preliminary efficacy of home-based 60Hz intermittent light therapy in adults with a major depressive episode (MDE). Participants will be randomized in a 2:1 ratio to receive either active or sham 60Hz intermittent light stimulation for 30 minutes daily (Monday through Friday) over three weeks. The light is delivered through a wearable headset. Clinical assessments will be conducted remotely at baseline, mid-point, post-treatment, and follow-up to measure changes in depressive symptoms.
- Detailed Description
This pilot study will evaluate the tolerability, usability, and preliminary impact of a novel wearable device delivering 60Hz intermittent light for treatment of depressive symptoms in adults with MDD. All procedures are conducted remotely.

- Primary Outcome Measures
Name Time Method Proportion of Participants who Complete all Scheduled Sessions Up to Week 3 Measure of retention; 15 sessions scheduled in total.
Proportion of Participants who Discontinue due to Adverse Effects Up to Week 3 Measure of tolerability.
Average Percentage of Completed Sessions Up to Week 3 Measure of adherence; 15 sessions scheduled in total.
- Secondary Outcome Measures
Name Time Method Change in Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR) Score Baseline, Week 3 The QIDS-SR is a 15-item scale assessing depressive symptoms over the previous 7 days. Each item is rated on a 4-point Likert scale from 0 to 3. The total score is the sum of responses and ranges from 0-45; higher scores indicate greater prevalence of depressive symptoms.
Adverse Events Week 3 Incidence of spontaneously reported adverse events during the intervention period. Incidence and type will be reported in the "Adverse Events" section of the results.
Change in Work and Social Adjustment Scale (WSAS) Score Baseline, Week 3 The WSAS is a 5-item scale assessing the impact of mental health on daily activities. Each item is rated on a 9-point Likert scale from 0 to 8. The total score is the sum of responses and ranges from 0-40; higher scores indicate more severe impairment on daily activities.
Change in Generalized Anxiety Disorder (GAD-7) Score Baseline, Week 3 The GAD-7 is a 7-item scale assessing the severity of generalized anxiety disorder. Each item is rated on a scale from 0 to 3. The total score is the sum of responses and ranges from 0-21 with higher scores indicating more severe anxiety.
System Usability Scale (SUS) Score Week 3 The SUS is a 10-item assessment of the usability of the intervention; the items are rated on a scale from 1-5. The total score is the sum of responses and ranges from 10 to 50; higher scores indicate greater usability of the intervention.
Change in Montgomery-Åsberg Depression Rating Scale (MADRS) Score Baseline, Week 3 The MADRS is a 10-item assessment of depression; each item is rated on a 7-point scale from 0 to 6. The total score is the sum of responses and ranges from 0 to 60; higher scores indicate greater severity of depression.
Change in Hamilton Depression Rating Scale (HDRS-17) Score Baseline, Week 3 The HDRS-17 is a 17-item scale assessing the severity of depression. Most items are rated on a 5-point scale (0-4), with some using a 3-point scale (0-2). The total score is the sum of responses and ranges from 0-52; higher scores indicate greater severity of depression.
Change in Patient Health Questionnaire (PHQ-9) Score Baseline, Week 3 The PHQ-9 is a 9-item scale assessing the prevalence of depressive symptoms. Each item is rated on a 4-point Likert scale from 0 to 3. The total score is the sum of responses and ranges from 0-27; higher scores indicate greater prevalence of depressive symptoms.
Net Promoter Score (NPS) Week 3 The NPS is a single-item questionnaire asking participants how likely they are to recommend the intervention to a colleague. The total score ranges from 1-10; higher scores indicate greater likelihood of promoting the intervention.
Brief Blinding Questionnaire (BBQ) Score Week 3 After completing the intervention phase of the study, effectiveness of participant blinding will be assessed using a 3-item questionnaire. The outcome will be scored as the percentage of participants who correctly guess their blinding assignment.
Post-Study System Usability Questionnaire (PSSUQ) Score Week 3 The PSSUQ assesses the overall usability of the intervention; each of the 16 items is rated on a scale from 1-7. The total score is the sum of responses and ranges from 16 to 112; higher scores indicate greater usability of the intervention.
