Brief Summary:
This study aims to develop and evaluate new 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.

Detailed Description:

This study aims to develop, refine, and evaluate a new 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. Caregivers in the full operation condition will have fewer negative effects of caregiving (lower burden, better mental and physical health, higher well-being) than those in the control condition.
  2. Greater use of the social networking features of the system will be associated with fewer caregiver depressive symptoms.
  3. Greater utilization of the home safety features of the system will be associated with fewer caregiver anxiety symptoms.

Arm Intervention/treatment
Experimental: In-Home Technology System
Participants will receive and install the full system (sensors for entry, activity, temperature, water leak; voice control; digital display; local router) in their homes. Remote assistance will be provided to help with the installation. Sensors, warnings, messaging, and social networking features will be activated remotely. Participation will extend over a six month period with questionnaires (e.g., health and well-being) administered 3 times (at the time of installation and every 3 months thereafter).
Device: In-Home Technology System and Questionnaires
Participants self-install the in-home technology system in their homes after enrollment in the study (i.e., consent procedures and initial questionnaire). Intelligent bots monitor the in-home sensors, learn typical patterns, and provide caregivers with text messages via cell phone and alerts via the tablet when worrisome behaviors occur. Social contact is encouraged using caregiver resources and a trusted circle of friends and family who are encouraged to stay in contact with the caregiver and person with dementia or mild cognitive impairment.

Waiting Control
Participants will be assigned a date for receiving and installing the full system (sensors for entry, activity, temperature, water leak; voice control; digital display; local router) six months after they enter the study. During that six-month period, questionnaires (e.g., health and well-being) will be administered 3 times (at the start of the study and every 3 months thereafter). At the end of the six-month period, participants will receive and install the full system (sensors for entry, activity, temperature, water leak; voice control; digital display; local router) in their homes. Remote assistance will be provided to help with the installation. Sensors, warnings, messaging, and social networking features will be activated remotely. Participation will extend over an additional six-month period with questionnaires (e.g., health and well-being) administered 2 times (every 3 months following installation).

Primary Outcome Measures :
  1. 3 Months Assessment for Center for Epidemiological Studies Depression Scale (CES-D) [ Time Frame: 3 months after baseline ]
    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.

  2. 6 Months Assessment for Center for Epidemiological Studies Depression Scale (CES-D) [ Time Frame: 6 months after baseline ]
    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.

  3. 3 Months Assessment for Zarit Burden Interview-Short Form [ Time Frame: 3 months after baseline ]
    Questionnaire to measure caregiver burden (Zarit, Reever, & Bach-Peterson, 1980). 12 items are rated on 0-4 scale. Range: 0-48. No subscales. Higher scores represent worse outcomes.

  4. 6 Months Assessment for Zarit Burden Interview-Short Form [ Time Frame: 6 months after baseline ]
    Questionnaire to measure caregiver burden (Zarit, Reever, & Bach-Peterson, 1980). 12 items are rated on 0-4 scale. Range: 0-48. No subscales. Higher scores represent worse outcomes.

  5. 3 Months Assessment for Beck Anxiety Inventory (BAI) [ Time Frame: 3 months after baseline ]
    Questionnaire to measure anxiety (Beck, Epstein, Brown, & Steer, 1988). 20 items are rated on a 0-3 scale and summed (range= 0-60). Higher scores indicate worse outcomes. There are no subscales. A score greater than 36 is considered to be clinically significant.

  6. 6 Months Assessment for Beck Anxiety Inventory (BAI) [ Time Frame: 6 months after baseline ]
    Questionnaire to measure anxiety (Beck, Epstein, Brown, & Steer, 1988). 20 items are rated on a 0-3 scale and summed (range= 0-60). Higher scores indicate worse outcomes. There are no subscales. A score greater than 36 is considered to be clinically significant.

  7. 3 Months Assessment for Satisfaction With Life Scale [ Time Frame: 3 months after baseline ]
    Questionnaire measuring overall life satisfaction and well-being (Diener, Emmons, Larsen, & Griffin, 1985). 5 items scored on a 1-7 scale and summed (Range = 5-35). Lower scores indicate worse outcomes. A score of 20 is considered neutral with higher scores considered increasingly more satisfied and lower scores considered increasingly more dissatisfied.
