Experimental: Home visit intervention by community health workers

The caregiver-centered, culturally and language specific home visit intervention with wearable devices (smartwatch/ring) will be delivered by trained bilingual community health workers (CHW) for Latino, Vietnamese, Korean, non-Hispanic White caregivers of PWD. The home visit intervention components will include (1) stress reduction techniques; mindful breathing and compassionate support/listening and (2) weekly education on dementia caregiving skills to handle difficult behaviors of PWD and knowledge of resources available for dementia care. The duration of the intervention will be 12 weeks that include 6 home visits (4 times for the first month and then once a month for two months) carried out in the participant's home. The on-site home visit intervention delivered by CHWs will focus on stress reduction techniques and caregiving skills education for 4 weeks and two monthly caregiver-driven topics for the following two sessions.

Active_comparator: Attention Control with wearable smartwatch/ring

The caregivers randomly assigned to the Attention Control (AC) group will be asked to wear smartwatch during the day time and smart ring during the night for 3 months in order to monitor their physiological measures (heart rate variability, heart rate, activities, sleep quality). CHW will give AC participants an overview of WIOT instruction at the baseline home visit. Caregivers will also receive resource information regarding Alzheimer's association and local social service information. CHWs will contact them monthly via phone for 6 months asking about the WIoT technology and answering general questions from participants. CHW will also visit participants' home at baseline, 3 months, and 6 months to administer survey assessments.

Placebo_comparator: Usual Care Group

The caregivers randomly assigned to Usual Care (UC) group will receive resource information regarding Alzheimer's association and local social service information at the baseline home visit by CHW. At recruitment, the participants will be told that at the end of the 6 months they will receive a smartwatch and a smartring for their participation. CHWs will contact them monthly for 6 months by phone answering only general questions from participants. CHW will also visit participants' home at baseline, 3 months, and 6 months to administer survey assessments.
