Experimental: Mindfulness Meditation (MM)

8-week mindfulness meditation program is based on Kabat-Zinn's MBSR program and will be led by MBSR-trained facilitators. The program has been modified to make it more accessible to caregivers. Weekly sessions will be 120-minutes long (instead of original 150-180-minute sessions). Formal meditation practices described in the original MBSR program (i.e., body scan, sitting meditation, mindful movement, mindful eating and walking) will be taught, in addition to loving kindness meditation (LKM). Participants will be given guided meditation recordings and compliance with home practice will be monitored with a practice log. The prescribed home practice has been modified to accommodate the needs of the caregiver: each practice is offered in 5- to 10-minute intervals (5 min, 10 min, and 20 min practice) to accommodate the caregiver's schedule.

Active_comparator: Psychoeducation

Psychoeducation (PSY) condition will be similar to MM with respect to number and duration of weekly sessions and daily homework. PSY is a lecture-based program based on the 10 KeysTM to Healthy Aging Course, an evidence-based program for older adults. Each session focuses on a specific topic related to wellness (e.g., nutrition, physical activity, medical screening) and caregiver-specific topics (e.g., understanding dementia and neurodegenerative disease, legal and financial issues).

Active_comparator: Respite control

Participant allocated to RC will not be exposed to a program, but will be offered 120-minutes of weekly respite care. Caregivers will be asked to record how they spend respite hours each week.
