Persons with dementia will wear the tracking device (Care Companion) and the caregivers will be using the companion smartphone application.

Persons living with Alzheimer's Disease or Related dementias will wear the Care Companion smartwatch for approximately one month (stage I) or 6 months (stage 2). The Caretakers will utilize the smart phone application (app) to monitor the person wearing the watch and be alerted to elopements. The system will notify a caregiver if the person with dementia leaves a defined area (e.g., the home) via the application. In the tether mode (e.g., outside of the home), the system monitors the distance between the smartwatch and the caregiver's smartphone. When a separation distance exceeds a set threshold, the application will alert the caregiver and start tracking the location of the person with dementia by displaying the person's position on the caregiver's smartphone.

Caregivers will report the utility and perceptions system review checklist with 18 close-ended questions on a 5-point Likert scale (e.g., "Setting up the Care Companion system was easy") and 7 open-ended questions (e.g., "How do think the Care Companion system affected how you care for your relative?"). Scores can range from 18 to 90, with a higher score indicating higher acceptability and utility. Individual items will be reviewed for particular factor utility.

Caregiver burden will be assessed using the 19-item Benjamin Rose Institute Caregiver Strain Instrument. It is rated on a 4-point Likert scale. Scores greater than 8 for Mastery, greater than 10 for Relationship Strain or Health Strain, or greater than 5 for Social Isolation/Activity Restriction may indicate heightened risk and may warrant further clinical investigation.

Caregivers will use the 27-item Algase Wandering Scale-Version 2 (AWS-V2) measures ambulation patterns to indicate their care recipient's restlessness and inclination to wander and elopement frequency (e.g., boundary transgressions), which has been validated with community-dwelling persons with Alzheimer's Disease Related Dementias (ADRD). This scale will be modified to use the Likert scaling approach to reduce survey burden. The total score ranges from 23-92 with higher scores indicating more frequent wandering behaviors.

All Stage I participants will be asked to participate in a semi-structured interview to learn more about perceptions related cost, sensitivity of the geo-locating, appearance, and privacy or stigma concerns. This information will be summarized into codes and higher level themes using qualitative analysis approaches.

Number of crises and service utilization (including number of nursing home stays, number of bed days, assisted living stays in the past month, other residential care setting in the past month, overnight hospital stays in past month, and Emergency visits in past month) will be measured with five self-report items. Whether the event happened is a yes/no format, if yes, the study will sum the number of days or events.
