The impact of different care dependencies on people's willingness to provide informal care: a discrete choice experiment in Germany.

Background: Informal care provided by family members, friends, or neighbors is a major pillar in the German long-term care system. As the number of care-dependent older adults grow, ensuring their future care still relies on the willingness of family members, friends, or neighbors to assume the role of an informal caregiver. This study aimed to investigate the impact on people's willingness to provide informal care to a close relative with predominately cognitive compared to physical impairments.
