Abstract: Objective: To understand the experience of using mobile health technology in the older adults with cognitive frailty in the community, so as to provide a reference for the promotion and usage of mobile health technology in the cognitive frailty population. Methods: From November 2023 to January 2024, based on the phenomenological research design, we adpoted the purposive sampling method according to the principle of maximum differentiation to enroll, 16 seniors with cognitive frailty from 3 communities in Beijing. Then semi-structured one-on-one in-depth interviews were conducted to collect data, which was analyzed by means of Colaizzi's seven-step method. Results: The participants' experience of using mobile health technology in the community was summarized into 3 themes which could be classified into 9 sub-themes: actively embracing new technology (enjoying technological well-being, conforming to current life, and placing health demands); harvesting emotional gains (maintaining independence, strengthening health beliefs and a sense of gains, positive feedback of family support); technology application gap (technology alienation, lack of elderly-oriented technology design, privacy concerns). Conclusion: Community-dwelling older adults with cognitive frailty have a positive willingness to use mobile health technologies, but there is a technological application gap that needs to be bridged. Medical workers and related health technology developers should pay more heed to elderly-oriented design in the process of development and promotion of such technology, so as to cater more to the actual living situations of the target population.
