Dr. Steven Zarit has done considerable research as regards how the stress experienced by family caregivers can best be managed. His recent research focuses upon the benefits that caregivers derive when their elder attends a day care facility. This arrangement allows them a valuable respite from their caregiving efforts. His studies indicate that having this support even results in caregivers' level of stress hormones decreasing. 

Dr. Zarit developed the Zarit Burden interview that measures the extent to which caregiving might be placing a "burden" upon those who accept this "responsibility." It has been used extensively in both therapeutic and research settings.
