In this article, we explore the psychological process through which Vietnamese family caregivers adjust to their role as primary caregivers for their relatives with dementia. The study adopted a constructivist grounded theory approach to collect data with 30 face-to-face, semi-structured interviews with 20 self-identified primary caregivers of older adults with dementia in Vietnam. The core adjustment process, consisting of four stages (Experience, Acknowledgment, Experiment, and Acceptance [EAEA]), to caregiving role emerged from the data.
