Examining Antecedents of Factual Knowledge and Perceived Familiarity of COVID-19 Contact Tracing App: A Modified Cognitive Mediation Model.

This study employs a modified cognitive mediation model to investigate the role of health valuation and fear in shaping media attention, factual knowledge, and perceived familiarity with COVID-19 contact tracing apps. Data were collected from a national survey of 906 Singaporeans, and structural equation modeling was used to analyze the results. Findings indicated that both fear of COVID-19 and health valuation were positively associated with newspapers, television, and social media attention, with health valuation demonstrating a stronger association with each media type. This suggests that health valuation, as an intrinsic motivation, is more critical in information-seeking behavior related to emerging health technologies. However, media attention on all platforms did not correlate with factual knowledge of COVID-19 contact tracing apps, whereas attention to social media was positively associated with perceived familiarity with these apps. This result highlights the potential influence of social media in shaping public perceptions, warranting further investigation into the quality and accuracy of the information disseminated. News elaboration was found to have a positive association with both factual knowledge and perceived familiarity with COVID-19 contact tracing apps. This underscores the need for effective communication strategies to promote accurate understanding of health technologies and emphasizes the role of individual motivations in shaping media consumption and information processing.
