Channel selection and knowledge acquisition during the 2009 Beijing H1N1 flu crisis: a media system dependency theory perspective

Abstract

This study uses secondary data from a four-wave repeated cross-sectional survey to examine communication channel usage patterns and their effects on health knowledge acquisition during the different phases of the 2009 H1N1 crisis in Beijing, China. The results suggest that channel choice, particularly for mobile phone and interpersonal communication, varies as a function of different levels of threat during a crisis. Moreover, social groups like students, retirees, and professionals differed in their channel selection. The study concludes that television users have more H1N1 knowledge than non-users and that in most cases, interpersonal communication does not contribute to knowledge gains. The theoretical implications are discussed at the end.
