NCT03715465

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
