China25 participantsStarted 2023-09-06
Plain-language summary
Cross-sectional evidences suggest a relationship between early childhood sleep and cognitive as well as socio-emotional functions. However, the casual relation has not been fully revealed. The current study aims to perform a randomized lab-based crossover nap restriction study on preschoolers, to determine the effects of sleep restriction on preschoolers empathy, prosocial behaviors as well as executive functions.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This study looked at how restricting daytime naps affects preschoolers' empathy and self-control — if my child has been skipping naps, could that be contributing to challenges we're seeing with their behavior or emotional responses?
2The trial measured specific brainwave signals called N2 and Late Positive Potential to track emotional processing — what do these kinds of measurements tell us about how sleep affects my child's developing brain, and is there anything similar we should be watching for in my child?
3Since this study is now completed, has enough evidence come out of research like this to change any recommendations about nap schedules for preschool-aged children, and what would you suggest for my child specifically?
4Could the findings from a study like this apply to my child if they have other factors affecting their sleep, or would those factors change how relevant this research is to our situation?
5Are there any established guidelines or next steps you'd recommend — like a sleep evaluation — based on what studies like this one are finding about the importance of naps for emotional development in young children?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
