 For Veterans, the intervention will target Caregiver participation in home-based Veteran mobility activities. MS Caregivers report high burden, stress, and depression involved in caring for their loved ones, especially as mobility declines and these outcomes are related to physical and emotional health status of the patient. For Caregivers, the intervention will focus on improving Caregiver coping and on managing MS-related problems. Outcomes for both will be measured at baseline, 3 months, and 6 months.
