Family members--whether people related by birth and marriage or friends and neighbors (sometimes called a "family of choice")--are the main caregivers for millions of older Americans. These family caregivers assist those they care for with activities of daily living such as bathing and dressing, with instrumental activities of daily living such as transportation and management of finances, and with health care such as medication administration. Usually, family caregivers assume these responsibilities with little preparation. Nurses and social workers can do much to educate family caregivers about their roles and to support them as chronic care providers. Fifty-five nurses, social workers, advocates, and other leaders in family caregiving met on January 29 and 30, 2008, in Washington, DC, for an invitational symposium. The collaborative consensus symposium was a joint project of the AARP Foundation, the "American Journal of Nursing," the Council on Social Work Education, and the Family Caregiver Alliance. Attendees explored the state of the science concerning nurses' and social workers' interventions with family caregivers. In addition, brainstorming sessions with small groups of about seven symposium participants each brought diverse backgrounds and perspectives to the table. At the end of each small-group work session, each group presented its conclusions to the group as a whole. This article presents the work of the groups at the symposium.
