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

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)
