The CDC and State Health Department Facebook Messages: An Examination of Frames and the Extended Parallel Processing Model

摘要

Public health organizations such as the Centers for Disease Control and Prevention (CDC) and state and local health departments are increasingly using social media in health education and promotion. Guided by the Extended Parallel Processing Model and framing theory, this study analyzed the Facebook messages of both the CDC and state health departments in 2017 to examine the extent to which such messages used these theories of social influence. All messages posted by the CDC in 2017 were downloaded. A multi-stage random sampling method was used to identify state-level health departments' posts. Differences were found in the CDC and state health organizations' Facebook messages in terms of the four EPPM variables. The CDC's Facebook posts were more likely to include severity, susceptibility, self-efficacy, and response efficacy than those posted by state health departments. In addition, while the state health departments were more likely to use gain frames, the CDC was more likely to use both gain and loss frames simultaneously.
