Summary

Many preschoolers with neurodevelopmental disorders struggle with sleep, which can worsen behavior and stress at home. This Hong Kong trial compares two ways of teaching parents sleep strategies: group sessions in person and a self-help mobile app, both added to usual care, against usual care alone. Researchers will track sleep, daytime behavior, and parent well-being over 12 months in 150 children aged 2 to 7.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Parent-led sleep training delivered in person or through a mobile app
What this could lead to
If it works, families could get a flexible, low-cost way to improve sleep for preschoolers with neurodevelopmental disorders, with benefits that may extend to daytime behavior and parent stress.
What could go wrong
This is a behavioral trial, not a cure, and sleep habits are hard to change. Some families may drop out, and results in Hong Kong may not apply elsewhere.
