研究概览
简要总结
There is evidence that some of the circadian photoreceptors, the intrinsically photosensitive retinal ganglion cells (ipRGCs), project directly to the amygdala, an area of the brain implicated in PTSD. Thus, a self-administered morning light treatment at home (shifts clock earlier and stimulates ipRGCs) may be a potentially efficacious adjunctive strategy for reducing PTSD symptoms. This study will test a 4 week daily 1 hour morning light treatment (active vs placebo) in individuals with PTSD. Outcome measures include measures of PTSD and depression.

结局指标
主要结局
Change in PTSD Checklist for DSM-5 (PCL-5) Scores Over 4 Weeks of Treatment
时间窗: Week 2 and Week 6
The PTSD Checklist for DSM-5 (PCL-5) is the gold standard measure of PTSD symptom severity. Range: 0-80. Higher scores indicate worse outcomes. We will assess change in PCL-5 scores over 4 weeks of treatment \[Week 2 through Week 6 of the study\].
次要结局
- Change in Patient Health Questionnaire - 9 (PHQ-9) Scores Over 4 Weeks of Treatment(Week 2 and Week 6)
