Treatment of Sleep Disturbances in School-age Children With Down Syndrome

The investigators long-term goal is to improve outcomes for children with Down syndrome (DS) and their caregivers. Towards that goal, the investigators propose a randomized clinical trial of a behavioral sleep treatment designed specifically for children with DS, documenting the impact not only on sleep, but also on the child\'s daytime inhibitory control and behavior problems, and the caregiver\'s sleep and stress levels. The investigators will randomize 80 families of children with DS ages 6-17 to receive either a 5-session behavioral sleep treatment (BST; targeting sleep education, behavioral principles and visual supports) or a general-education control condition (CON). The BST will cater to the unique needs of children with DS, adapting an intervention that successfully treats behavioral sleep disturbances in children with autism1. Pre- and post-intervention, children will undergo comprehensive assessments of cognitive, behavioral, and adaptive functioning involving direct testing and input from parents and teachers. Child and parent sleep will be monitored via actigraphy and parent-completed sleep diaries, and parents will report on their stress levels and mood.
