Study of Bedroom Environment Sleep Intervention at Home for Older Adults Living Alone With Memory Concerns

Summary

This is an eight-week pilot research study designed to test whether simple changes to the bedroom environment along with brief sleep hygiene strategies, can improve sleep in older adults who live alone, have memory concerns, and experience insomnia symptoms. Older adults may be eligible to participate. The intervention will take 8 weeks, which includes 1-2 in-person visits from the research team at the participant's residence (evaluate the bedroom environment, install participant-agreed bedroom changes, deliver target sleep hygiene strategy) and 2 virtual or telephone calls (support environmental and sleep hygiene strategies) over 8 weeks. Sleep and environment data will be collected at screening/baseline, mid-intervention (4-week) and post-intervention (8-week)

Conditions

• Subjective Cognitive Decline (SCD)
• Mild Cognitive Impairment (MCI)
• Insomnia

Interventions

BEHAVIORAL

Bedroom Environment Tailoring

Within two weeks of completing the parent study and consent, participants begin the personalized bedroom sleep environment program. During in one or two in-home visits, a research team member will review baseline sensor and actigraphy data and install low-cost environmental modifications (e.g., blackout shades, white-noise device, air purifier, thermostat adjustments). Participants collaborate with the coach to set stimulus-control goals and receive individualized sleep-hygiene guidance. A 30-45-minute virtual follow-up in Weeks 2-3 reviews progress and addresses barriers, with a brief Week 6 check-in to reinforce goals. Ongoing support includes daily self-practice, optional between-visit contact, automated reminders, and passive sensor monitoring to promote adherence and confidence in managing sleep.

BEHAVIORAL

Sleep Health Education

The control group receives a single in-person or virtual session that provides participants with printed and online sleep health education materials. This introductory session aims to equip participants with foundational knowledge about sleep hygiene. Following this initial session, participants will engage in eight weeks of self-directed practice, allowing the participant to apply the information learned at the participant's own pace.
