Does the proposed intervention need to be tested across the entire Aging Continuum?

No, the proposed intervention(s) do not need to be tested across the entire continuum, but it needs to address at least one of the domains (e.g., (a) Maintain function and independence, (b) Facilitate chronic disease management, (c) Support individuals with significant functional impairment, and (d) Reduce caregiving burden and improve quality of life.) However, it is possible for an intervention to address multiple domains.
