Overview
The goal of this study is to examine the relationship between sensory responsivity, bedtime arousal levels, sleep disturbances, and daytime emotion dysregulation for autistic children (ages 6-10). In a subset of children with elevated sensory responsivity, a sensory-based bedtime manipulation targeting bedtime arousal levels will be tested.
Description
This study is a cross-sectional study with a pilot pre-post intervention trial with a subset of participants. A total of 60 autistic children and caregivers will be recruited to complete questionnaires, one lab visit during which sensory responsivity to standardized sensory stimuli will be measured, and two weeks home-based data collection using daily diaries and actigraphy devices (both caregiver and child).
In a subset of 30 participants with elevated sensory over-responsivity and bedtime resistance, participants will be invited to complete the second part of the study- a open pilot study. These participants will complete a baseline interview and a lab-based training session to learn the caregiver-mediated Power Down protocol. The Power Down protocol is a standardized gentle pressure massage with a mindfulness script that aims to decrease autonomic arousal through proprioception and tactile input. Caregivers will complete the Power Down and a home-based data collection protocol for 2 weeks. During this time, caregivers and child will also wear actigraphy devices and complete daily diaries. Upon completion of the study, participants will complete exit questionnaires and an exit interview.
