Use of a Personal Sleep Self-Monitoring Device for Sleep Self-Management: A Feasibility Study.
Maral Torossian, Raeann G LeBlanc, Cynthia S Jacelon
PMID 33377982WHAT IT FOUND
Older adults wearing a sleep tracker for four weeks showed high adherence and retention, but no significant changes in sleep quality, duration, or health scores.
The device was feasible for self-monitoring and goal setting, but did not improve sleep outcomes in this small pilot.
Key findings
01Participants had high adherence to wearing the device, with data available for 94.79% of the monitoring period, and 92% completed the study.
02There were no statistically significant changes in total sleep time, restful sleep time, sleep quality, or physical and mental health scores after the intervention.
03Participants in the intervention groups used the device data to set specific sleep goals, such as establishing a set bedtime routine or limiting alcohol before bed.

What it does not show
The sample size was small (26 participants) and not powered to detect clinical changes, which explains the null results for sleep outcomes. The study did not achieve its target sample size of 35 participants due to time-bound recruitment. The device used (Misfit Shine) had frequent battery failures, which required additional support and may affect real-world usability. The study did not assess potential health-related anxiety caused by monitoring sleep data.
The easy way to misread this
Do not conclude that personal sleep monitoring devices improve sleep quality or health outcomes in older adults. The study was a feasibility trial with a small sample size and explicitly found no statistically significant changes in any sleep or health measures.
