Aim: Despite efforts to revise the traditional long‐term care (LTC) model, informal caregivers continue to provide a substantial amount of support to older adults as front‐line care providers. The present study aimed to understand the effect of informal caregiving on caregivers’ well‐being in Singapore with respect to different types of patient–caregiver relationships. Second, this study examined the association between formal LTC service use and caregivers’ well‐being.
