Over 15 million family caregivers provide more than 85% of long-term care to older adults with Alzheimer's Disease and Related Disorders. Caregivers typically assume care responsibilities without training or support and may in turn experience multiple health risks including depression. Providing evidence-based caregiver supportive programs on a wide scale basis is identified by the National Alzheimer's Plan Act as a national priority. One approach is to augment existing community-based services for older adults with a caregiver evidence-based program. Adult day service (ADS) is one such growing and critical community-based option for older adults with Alzheimer's Disease and related disorders but which does not systematically address common caregiver challenges or burdens using evidence-based programs. The purpose of the study is to: 1) evaluate the effectiveness of Adult Day Services (ADS) Plus to improve caregiver well-being and reduce depressive symptoms compared to routine ADS use at 6 months; and 2) evaluate long-term maintenance effects of ADS Plus at 12 months on caregiver well-being and depressive symptoms. ADS Plus consists of 5 key components: care management, referral/linkage, education about dementia, situational counseling/emotional support/stress reduction techniques, and skills to manage behavioral symptoms (e.g., rejection of care, agitation, aggression). Based on care challenges identified by family caregivers, an "ADS Plus Prescription" is provided, a written document detailing easy-to-use strategies to address specified care challenges and caregivers are trained in their use. The proposed study will employ a practical trial design to assess the effectiveness and uptake of ADS Plus on a large scale. Thirty ADS programs throughout the U.S. varying in geographic location and staffing levels will be involved. A total of 300 diverse caregivers (150 in 15 ADS Plus sites; 150 in 15 ADS usual care sites) will be enrolled.
