Join research study on delayed sleep-wake phase disorder

Do you have trouble falling asleep before 1 a.m.? Do you find it difficult to wake up early in the morning for your commitments? Does your high schooler have a hard time falling asleep before 1 a.m. and waking up early in the morning/for high school? 

The Sleep and Chronobiology Laboratory is looking for people with delayed sleep-wake phase disorder or people with late bedtimes—or healthy people with typical bedtimes. 

Eligibility

Researchers are looking for males and females, ages 16–40, to participate in a 6.5-weeklong study with six in-person visits. You may be eligible for this study if you:

  • Have a diagnosis of delayed-sleep wake phase disorder or have late bedtimes after 1 a.m., an inability to fall asleep and difficulty awakening when required for school/work
  • Or are healthy with typical bedtimes and no sleep concerns 

What should you expect during the study? 

  • Health screening
  • Monitor on separate occasions your sleep, mood, eating times for one or two weeks and blood sugar levels while living at home
  • Live in the sleep laboratory on two separate occasions for 51–66 hours (approximately 4.87 days in total) 
  • Blood and saliva sampling 
  • A few blood samples and more frequent saliva sampling 
  • Testing on reaction time, mood and ability to think 

Compensation is up to $2,009. If you have any other questions, please email sleep.study@colorado.edu and ask about the Circadian Rhythms and DSWPD study, or call 303-735-1923.
