Brief Summary
This study will test whether measuring the circadian clock during treatment of delayed sleep-wake phase disorder results in greater improvements in sleep compared to estimating the circadian clock.

Outcome Measures
Primary Outcomes (1)
Change From Baseline Time of Dim Light Melatonin Onset (DLMO) at 4 Weeks
Onset of melatonin in dim light conditions as measured in saliva (also called DLMO). Time of DLMO is measured in clock time and change in time of DLMO is measured in hours. The change score is calculated as time at 4 weeks minus baseline time. Thus, positive scores indicate a shift towards a later onset of melatonin and negative scores indicate a shift towards an earlier onset of melatonin.
After 4 weeks of melatonin therapy
Secondary Outcomes (13)
Change From Baseline Score on Wrist Actigraphy and Self-Report Diary Sleep Diary Parameters - Total Sleep Time at 4 Weeks
After 4 weeks of melatonin therapy
Change From Baseline Score on Wrist Actigraphy and Self-Report Diary Sleep Diary Parameters - Sleep Onset Time at 4 Weeks
After 4 weeks of melatonin therapy
Change From Baseline Score on Wrist Actigraphy and Self-Report Diary Sleep Diary Parameters - Sleep Offset Time at 4 Weeks
After 4 weeks of melatonin therapy
Change From Baseline Score on Wrist Actigraphy and Self-Report Diary Sleep Onset Latency at 4 Weeks
After 4 weeks of melatonin therapy
Change From Baseline Score on Epworth Sleepiness Scale at 4 Weeks
After 4 weeks of melatonin therapy
- +8 more secondary outcomes
Study Arms (2)
Estimated DLMO
ACTIVE COMPARATORFour weeks (28 days) of nightly melatonin 0.5 mg fast dissolve tablets timed to be administered 3 hours before estimated dim light melatonin onset.
Measured DLMO
EXPERIMENTALFour weeks (28 days) of nightly melatonin 0.5 mg fast dissolve tablets timed to be administered 3 hours before measured dim light melatonin onset.
Interventions
Test to determine the time of melatonin onset in saliva under dim light conditions
