The job burnout of caregivers for older adults with dementia is a phenomenon worthy of great attention. Focusing on the theme of "job burnout" among institutional and family caregivers for older adults with dementia, this paper adopts the three-dimensional theory of Maslach as the research perspective. Based on in-depth interviews with family and institutional caregivers for older adults with dementia in three cities of Anhui Province, it uses grounded theory to analyze their "job burnout" dilemmas. The study finds that caregivers' job burnout stems from stress accumulation in direct interaction environments, the fragility of social support networks, and deviations in socio-cultural cognition and occupational stigmatization. Accordingly, coping strategies are proposed from individual, social support, and organizational levels, aiming to provide theoretical reflections and practical experience for caregivers' self-perceptions and their roles in elderly care services.
