ABSTRACT
Background: The COVID-19 pandemic caused by the novel SARS-CoV-2 virus represents an ongoing public health challenge that necessitates a heightened need to understand people's risk perceptions as well as their information-seeking behavior. Objective: The aim of this study is to explore the impact of different information-seeking behaviors on people's risk perceptions during the COVID-19 pandemic. Methods: We employed convenience sampling in order to administer questionnaires to 3048 residents in Hunan Province, China. After screening the questionnaires for inclusion in the study, multiple linear regressions were then used to analyze the impact of the characteristics of respondents' information-seeking behavior on their risk perceptions. Results: From the 3048 distributed 2611 were included. New media (80.20%) was the most frequently used source of information seeking, and traditional media were participants' most trusted source of COVID-19 information. Statistics of COVID-19 were the type of information most frequently queried by respondents, and approximately 30.0% of them reported that most or all of the COVID-19 information they sought was negative. Approximately one in five respondents reported that they sought COVID-19 information more than 10 times per day. The results of our multivariate linear regression analysis showed that "seeking information from new media ", "level of trust in new media and local propaganda", "information content being about protective behaviors and personal related information", "proportion of negative information", and "frequency of information seeking" were positively associated, and "seeking information from traditional media" and "level of trust in traditional media" were negatively associated with people's risk perception of COVID-19. Conclusion: We find that specific types of channels of information acquisition and public trust in these information channels, their informational content, and proportion of negative information, as well as a frequency of information seeking all had an impact on risk perception during COVID-19.
ABSTRACT
OBJECTIVE: Correctly understanding and evaluating the level of public risk perception toward public health emergencies not only helps experts and decision-makers understand the public's preventative health behaviors to these emergencies but also enhances their risk information communication with the public. The aim of this study was to develop a risk perception scale for public health emergencies and test its validity and reliability during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: Guided by the theoretical model of risk perception, an initial scale was generated through literature review, group meetings, resident interviews, and expert consultation. A pretest and item screening were then conducted to develop a formal risk perception scale for public health emergencies. Finally, the reliability and validity of the scale were validated through a questionnaire survey of 504 Chinese adults. RESULTS: The final scale had 9 items. The content validity index of the scale was 0.968, and the content validity index of individual items ranged from 0.83 to 1.00. Three common factors, dread risk perception, severe risk perception, and unknown risk perception, were extracted for exploratory factor analysis, and together they explained 66.26% of the variance in the score. Confirmatory factor analysis showed that the model had a satisfactory fit, where χ 2/df = 1.384, the goodness-of-fit index (GFI) = 0.989, root mean square error of approximation (RMSEA) = 0.028, root mean square residual (RMR) = 0.018, comparative fit index (CFI) = 0.995, normed fit index (NFI) = 0.982, and non-normed fit index (NNFI) = 0.990. The correlations between dimensions ranged from 0.306 to 0.483 (P < 0.01). Cronbach's α was 0.793 for the total scale and ranged between 0.687 and 0.801 for the individual dimensions. The split-half coefficient was 0.861 for the total scale and ranged from 0.727 to 0.856 for induvial dimensions. The test-retest coefficient was 0.846 for the total scale and ranged from 0.843 to 0.868 for induvial dimensions. CONCLUSION: The developed scale for the risk perception of public health emergencies showed acceptable levels of reliability and validity, suggesting that it is suitable for evaluating residents' risk perception of public health emergencies.
