Sleeping Late Teens (SLATE) Study – Ages 18 & 19
STUDY BASICS
Are you 18-19 years old and currently enrolled in 11th or 12th grade? If so, you may be eligible to participate in a research study to help find out if sleep timing affects teens’ mood and behavior. Study involves at-home sleep tracking, 1-2 overnight sleep lab visits, 1-2 fMRI scans, and other assessments. Compensation provided.
STUDY PURPOSE
Sleep is important for teenagers’ physical and mental health, but early wake times during the school year can make it difficult for teens to get enough sleep. The purpose of this study is to learn more about how teens’ sleep schedules affect their mood and behavior. Researchers hope their findings will lead to better ways to prevent and treat sleep-related problems in teens in the future.
COULD THIS STUDY BE RIGHT FOR YOU?
- Age 18 or 19
- Currently enrolled in 11th or 12th grade
- Not currently diagnosed with any unstable, chronic health conditions
- Willing and able to undergo fMRI scanning (not claustrophobic, no non-removal metal in the body, not pregnant)
WHAT PARTICIPANTS CAN EXPECT
Participation involves a two-part screening period that includes a website survey or telephone interview and a 2-hour in-person screening visit. If eligible after screening, you will be randomly assigned (like the flip of a coin) to one of two groups. Participants in both groups will track their sleep at home for 7 days, have 1-2 overnight visits to the sleep lab, have fMRI brain scans, and have brief bi-monthly online follow-up assessments for up to 4 years. One group of participants will be asked to change their sleep schedule and the other group will sleep as they normally do.
