  Purpose
Delayed Sleep Phase Disorder (DSPD) is a sleep disruption that commonly occurs in teens and manifests as a difficulty in waking up in the morning, going to sleep early enough at night, and daytime disturbances such as depression, fatigue, and restlessness. The purpose of this study is to determine if brief flashes of light, that are scheduled to occur during sleep, are effective in treating DSPD.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Treating Sleep Disruption in Teens With Millisecond Light Exposure During Sleep

Arms Assigned Interventions
Experimental: Light
three hours of a sequence of light flashes (4000 lux, 3 msec, every 30 seconds); occurs during three hours immediately prior to desired waketime
Device: Flashes
three hours of a sequence of light flashes (4000 lux, 3 msec, every 30 seconds); occurs during three hours immediately prior to desired waketime
Placebo Comparator: Fake light
during three hours immediately prior to desired waketime, subjects will receive no light (light flash device will be disabled)
Device: Flashes
three hours of a sequence of light flashes (4000 lux, 3 msec, every 30 seconds); occurs during three hours immediately prior to desired waketime
