[Purpose/significance] Focusing on the main factors that affect the satisfaction of elderly users with infor⁃mation disclosure in public health emergencies, this research explores the impact and relationship between them to re⁃veal the mechanism of elderly user satisfaction, in order to provide reference for governments at all levels to optimize the form of information disclosure work and improve information disclosure services in public health emergencies, in or⁃der to better meet the information needs and expectations of elderly users. [Method/process] The elderly population is the specific research subjects in the article, conducting a systematic analysis of the survey data obtained using structur⁃al equations. Based on hypothesis verification, a model of factors affecting the satisfaction of elderly users with public health emergencies information disclosure is constructed. [Result/conclusion] The model, with trust level, subjective ability, demand expectations, and social support as independent variables and perceived accessibility, perceived quali⁃ty, and perceived value as intermediate variables, reveals that the satisfaction of elderly users with information disclo⁃sure in public health emergencies is a chain reaction process result of multiple complex factors, revealing the informa⁃tion psychology and behavioral characteristics of the elderly population in this area.
