Sleep Extension and Behavior of Young Children

Not Applicable

Completed

• Conditions: Attention Deficit Hyperactivity Disorder
• Interventions: Behavioral: Sleep Extension

• Registration Number: NCT03446716
• Lead Sponsor: University of Massachusetts, Amherst

Brief Summary

This pseudo-randomized intervention study examined change in inhibitory control following a sleep manipulation in which children with and without ADHD were instructed to advance their bedtime by 90 minutes for five days.

Detailed Description

Objective: To evaluate the efficacy of a sleep extension intervention in young children with ADHD and determine whether sleep extension improves inhibitory control, a primary deficit in ADHD.

Design: Children with and without ADHD completed two 5-day assessments: a baseline condition in which children followed their normal bedtime routine and a sleep extension condition in which children were instructed to go to bed 90 minutes earlier than their habitual bedtime. Sleep was assessed with actigraphy and, on the final night, polysomnography. A Go/No-Go task was used to assess inhibitory control.

Setting: Participants slept in their home on nights 1-4 and in the sleep laboratory on night 5 of each condition.

Main Outcomes and Measures: Of interest is actigraph measurement of total sleep time for the baseline compared to the sleep extension condition. Polysomnography will be used to compared changes in sleep physiology. The primary behavioral outcome is inhibitory control, indexed by accuracy on No-Go trials in the Go/No-Go task.

Arm && Interventions

Group	Intervention	Description
EXTENSION	Sleep Extension	During the extension condition, caregivers were instructed to put their child to bed 90 minutes earlier than their habitual bedtime for five consecutive nights. Caregivers were provided a list of tips to aid in implementing the earlier bedtime.

Primary Outcome Measures

Name	Time	Method
total sleep time	5 days (actigraph watch is worn for 5 days in each condition and overnight sleep time is identified and averaged across these 5 days)	average nightly across 5 nights

Secondary Outcome Measures

Name	Time	Method
inhibitory control	measured before and after sleep - about 12 hrs	measured with the Go/NoGo task
