Background and Objectives Few studies have simultaneously compared caregivers in all stages of the adult life course. This study examined age differences in associations among primary stressors (caregiver burden which includes hours of provided care and number of activities of daily living and instrumental activities of daily living performed), secondary stressors (financial and employment strains), and caregiver outcomes (emotional strain and physical strain). Research Design Using Pearlin’s Stress Process Model (1990) and the Caregiving in the United States 2015 dataset, 1,156 caregivers were identified (including 278 young adults aged 18–39 years, 464 midlife adults aged 40–59 years, and 414 older adults aged 60–80 years). Results Post hoc analyses revealed that compared to older adults, young adults reported less caregiver burden, less physical strain, and greater financial strain. Linear regression analyses revealed associations between caregiver burden and financial strain with emotional and physical strain for all respondents. Discussion and Implications Findings emphasize the need for age-specific interventions.
