Measuring information overload and message fatigue toward COVID-19 prevention messages in USA and China

Abstract

SummaryCOVID-19 prevention messages are a crucial component of disease mitigation strategies and the primary driver of health decision-making during the global pandemic. However, the constant and repetitive nature of COVID-19 messaging may cause unintended consequences. Among the commonly observed phenomena are information overload and message fatigue, which might be experienced differently depending on cultural background. Using measurement invariance testing, this study compared how individuals from two countries—USA (n = 493) and China (n = 571)—experienced information overload and message fatigue toward COVID-19 prevention messages. Findings revealed that people in China showed significantly lower level of information overload and message fatigue than those in the USA. This study explores the extent of the unintended persuasive effects that people have experienced during the COVID-19 pandemic in different societies, a comparison which has never been studied before, even outside of the context of COVID-19. The study also provides much-needed practical insights to develop public health initiatives that improve COVID-19 prevention communication, which can further reduce these unintended effects in both countries, and has implications for other countries as well.
