The Power Down Pilot Study: A Novel Bedtime Manipulation Protocol

Powering Down: A Pilot Study of a Bedtime Manipulation to Support Sleep for Autistic Children

• Status: Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 10 (estimated)
• Sponsor: University of Pittsburgh · Academic / Other
• Sex: All
• Age: 6 Years – 10 Years
• Healthy volunteers: Not accepted

Summary

The goal of this pilot intervention study is to examine the feasibility and acceptability of a novel bedtime manipulation protocol called "The Power Down" for autistic youth, ages 6-10. The main questions it aims to answer are: 1. Is the Power Down feasible for caregivers to do each night? 2. Do the families find the Power Down an acceptable intervention to address their child's difficulties settling down to fall asleep?

Detailed description

Interested participants will contact the research team and complete screening to determine eligibility (see Screener document). For eligible participants, the informed consent form will be sent and a consent call or video call will be scheduled. The study team will complete the consent process with eligible caregivers (on phone or via video call) and a consent form will be sent via DocuSign for the caregiver to sign. Following the consent process, questionnaires (below) will be sent via REDCap to complete and a in-lab training meeting will be scheduled. During the in-lab training meeting, the PI (Hartman) will complete the bedtime manipulation training (details found in the Power Down Protocol document found in the Basic Study Information section of this IRB). After the education training, the caregiver(s) will be instructed in the "Power Down massage" and they will practice with their child in the lab and receive feedback on their delivery of the massage. The caregiver(s) and their child will also be given an activity monitor and instructed on the use and care of the device. The caregiver(s) will also review the morning and evening diaries to be completed throughout the study with a study team member. Following the training session, the caregiver(s) and their child will complete the power down massage nightly, just prior to the time the child would start to try to fall asleep (e.g., after caregiver says "good night", when caregiver leaves the room), for two weeks. They will also complete a morning and evening diary entry, which will be sent virtually. At the end of the two weeks, the activity monitor will be returned to the study team. The participants will connect with the study team to complete an exit interview about their participation in the study and questionnaires about the treatment acceptability.

Interventions

Type	Name	Description
BEHAVIORAL	Power Down bedtime manipulation	The Power Down is a bedtime manipulation protocol targeting elevated arousal level at bedtime due to a hypothesized effect of sensory over-responsivity (a common experience for autistic children). The Power Down incorporates sensory-based tools (gentle tactile pressure and auditory cues) to support nervous system regulation prior to attempting sleep onset. Participants (caregivers and their child) will be educated in the Power Down protocol and data collection methods for the 2 week intervention trial. Caregivers will lead a nightly gentle massage with guided relaxation script just prior to the child trying to fall asleep. The child will also wear a watch-like activity monitor (ActiGraph GT9x) for the 2 week period throughout the day and night to measure changes in sleep and activity patterns. Caregivers will complete daily diary questions in the morning and evening reporting their child's emotions and sleep timing.
