Accurately assessing the needs of elders and their families is critical to developing an effective elderly service program or successful aging policy. In China and other Asian countries, such as Japan and South Korea, where the aging population is rapidly growing, this need is particularly apparent. Using case examples collected from a pilot study in urban China, we explore challenges in using the interview method for conducting needs assessments among elders and their family caregivers, including socio-cultural, cognitive, and conceptual limitations. To address these limitations, strategies are discussed to improve the use of interview methods for accurate assessments of needs among elders and their family caregivers, especially among those in developing countries, like China.
