Light Flashes to Treat Delayed Sleep Phase Disorder (DSPD)

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.

ArmDescriptionAssigned Intervention
Experimental
Light 		one hour of a sequence of light flashes (4000 lux, 3 msec, every 30 seconds); occurs during hour immediately prior to desired waketime
  • Device: Flashes
    one hour of a sequence of light flashes (4000 lux, 3 msec, every 30 seconds); occurs during the hour immediately prior to desired waketime
Placebo Comparator
Fake light 		during hour immediately prior to desired waketime, subjects will receive one light flash (insufficient to cause phase shift)
