The increase in prevalence of dementia over the last 50 years has resulted in a concomitant rise in the number of families facing the physical, emotional, and psychological stress associated with caregiving. Behavioral symptoms that occur in persons with dementia (PWD) lead to negative mental and physical health outcomes for caregivers and predict caregiver decisions to institutionalize PWD. Resources to Enhance Alzheimer's Caregiver Health - VA (REACH VA), has demonstrated its ability to improve caregiver burden, emotional and physical well-being, social support and management of behavioral symptoms. Although REACH VA represents one of the best available approaches to help caregivers, treatment non-response and modest treatment effects remain significant issues. A variety of factors may be associated with non-response to behavioral intervention - one particularly robust predictor of non-response is interpersonal skill and communication.
