Study summary

This study aims to develop, evaluate, and commercialize an in-home supportive technology that is designed to alleviate anxiety, burden, and loneliness in spousal and familial caregivers of individuals with Alzheimer's disease, other dementias, or mild cognitive impairment in rural homes.

Read the detailed description

This study aims to develop, refine, evaluate, and commercialize a hardware/software system designed to integrate in-home sensors and devices, Internet-of-Things technologies (i.e., devices that can be controlled and communicated with via the internet), and social networking to create a more safe and supportive home environment for caregivers and people who have Alzheimer's disease, other dementias, or mild cognitive impairment. The system monitors troublesome behaviors in people with dementia or mild cognitive impairment (e.g., wandering), and targets mechanisms (e.g., worry, social isolation) thought to link behavioral symptoms in people with dementia or mild cognitive impairment with adverse caregiver outcomes (declines in health and well-being). The system is designed to minimize demands on caregivers' limited time and energy and to provide a platform for data collection that can be used by researchers and care professionals.

Hypotheses:

  1. Rural caregivers in the active treatment condition will have better health and well-being (i.e., less caregiver depression, anxiety, loneliness, and burden) and higher user satisfaction compared to those in the control condition.
  2. The magnitude of the difference in health and well-being and user satisfaction for rural caregivers in the active treatment condition compared to those in the control condition will increase over time (reflecting additional bot learning and ability to adjust to changing caregiver needs).
  3. In the active treatment condition, greater utilization of features (e.g., selecting and receiving warnings, obtaining daily reports, accessing social support services) will be associated with better caregiver health and well-being and higher user satisfaction.

Study arms

  • Experimental
    In-Home Technology System

    The full system \[(a) 1 advanced gateway with a dual-SIM cellular connection to communicate/control the equipment; (b) 5 indoor motion sensors; (c) 3 door/cabinet entry sensors; (d) 1 water leak sensor; (e) 1 "call for help" button; (f) 2 motion-activated LED night lights; (g) 2 Vayyar fall detection and sleep quality sensors\] will be self-installed by 60 rural caregivers in their homes. Monitoring of sensors, provision of warnings, messaging, and social networking features will be activated remotely for those participants who have been randomly assigned to this arm. Participation will extend over a 6 month period with questionnaires (e.g., health and well-being) administered 3 times (at the time of installation and every 3 months thereafter).

    Limited In-Home Technology System

    The full system \[(a) 1 advanced gateway with a dual-SIM cellular connection to communicate/control the equipment; (b) 5 indoor motion sensors; (c) 3 door/cabinet entry sensors; (d) 1 water leak sensor; (e) 1 "call for help" button; (f) 2 motion-activated LED night lights; (g) 2 Vayyar fall detection and sleep quality sensors\] will be self-installed by 60 rural caregivers in their homes. Only monitoring of the water leak sensor and associated warnings will be activated remotely for those participants who have been randomly assigned to this arm.

    Device: Limited In-Home Technology

Interventions

  • DeviceIn-Home Technology System

    Intelligent bots monitor the in-home sensors, learn typical patterns, and provide caregivers with text messages and alerts via cell phone when worrisome behaviors occur. Caregivers are able to: (a) select services (e.g., warnings for falls, wandering, late night activity); (b) access daily reports (summaries of daily activities that can also be shared with health care providers); and (c) obtain support (e.g. Caregiver Support Groups that connect caregivers with knowledgeable experts and other caregivers, Caregiver Events that provide virtual meetings about relevant topics, and Trusted Circle task management to distribute the caregiving work load).

What researchers measure

Primary outcomes

  1. 3 Months Assessment for Center for Epidemiological Studies Depression Scale (CES-D)

    Questionnaire to measure depression (Radloff, 1977). 20 items are rated on a 0-3 scale and summed (range = 0-60). There are no subscales. Higher scores represent worse outcomes. The clinical cut-off is usually set at a score of 16.

Results

Posted Jan 7, 2025
Limitations and caveats
Enrollment was challenging in this rural population. Thirty-eight caregivers initially expressed interest by completing a screening questionnaire but then were unreachable or declined participation before enrolling. Furthermore, 27 caregivers enrolled and completed the first questionnaire packet, but 12 of them discontinued from the study prior to being assigned to one of the two groups.
