Information-Seeking Behavior for COVID-19 Boosters in China: A Cross-Sectional Survey

As China launches its second COVID-19 booster campaign and races to bring new vaccine technologies to protect against severe COVID-19 infections, there is limited research on how Chinese residents search for vaccine-related information. This study examined the factors influencing Chinese residents' information-seeking behaviors regarding COVID-19 boosters with a sample of 616 respondents with a mean age of 31.53 from a research panel. Structural equation modeling was used to report factors that influenced respondents' seeking intent. The results indicated that seeking-related subjective norms ( = -0.55, < 0.001), negative affect ( = 0.08, < 0.05), positive affect ( = 0.18, < 0.001), and perceived knowledge insufficiency ( = 0.10, < 0.001) are strong predictors of one's seeking intent. We also discovered that there was an inverse relationship between risk perception and positive affect ( = -0.55, < 0.001) and between negative and positive affect ( = -0.19, < 0.01), while all measurements were either directly or indirectly related to information-seeking intent. A few more indirect but important relationships were also included in our discussion. In conclusion, the present study helps understand what motivates Chinese residents to seek COVID-19 booster information when limited information is available.
