Abstract In current health information behavior research, the pressing focus is on persuading the public to adopt good health behaviors through health information dissemination or education. Following the elaboration likelihood model (ELM), this study divided the persuasive routes into central and peripheral routes, employing a short-term longitudinal design. A diary experiment spanning 10 days was used continuous health information use data from 30 college students (total 377 datapoints). To explore the persuasive mechanism of health information on health behavior willingness, a hierarchical linear model (HLM) was established at the individual, information clue, and time levels. Results indicate that clues mainly depend on a mixed persuasion route of information quality and source credibility. Additionally, over a seven-day period, the persuasive effect gradually strengthened. Information quality exhibited a more stable persuasive effect, while the effect of source credibility is diminished over time. Moreover, the persuasion route of health information is contingent on individual characteristics and usage time. Health awareness is time-dependent and moderates the effect of source credibility and information relevance. Involvement also moderates the effect of information quality and source credibility on persuasion, with no time dependency. This study sheds light on the persuasive mechanisms in health information for health behavior change and provides suggestions for developing “people-oriented” personalized health information dissemination and education programs.
