Guided by stress process and life course theory, the purpose of this study was to examine adult child caregivers’ psychological and physical health trajectories and how their multiple family (caregiving, marital, and parenting) and nonfamily (employment) roles contributed to these health outcomes over time. Seven waves of data from the Health and Retirement Study were analyzed for 1,300 adult child caregivers using latent growth curve models. Adult child caregivers have distinct psychological and physical health trajectories that are related to their roles over time. The importance of any given role varies by the type of health outcome and timing in the life course. Caregiving alone does not contribute to adult child caregivers’ psychological and physical health; marital and employment roles also contribute significantly to caregivers’ life courses.
