Purpose: This study examined how the amount of informal care received by disabled elders changes when they are receiving publicly paid home care, and whether formal service use, disability, caregiving arrangements, and demographic characteristics of older adults predict changes in the amount of informal care. Design and Methods: Hierarchical linear models were estimated, using 3-year data (12 repeated observations) collected from elderly participants (N = 888) in Michigan's Home- and Community-Based Medicaid Waiver Program.
