Mapping e-cigarette communication and dissemination on social media
Drawing upon the infodemiology and issue-attention cycle frameworks, we examined communication and information diffusion of electronic cigarettes (e-cigarettes) on social media. We analyzed 83,527 Facebook posts and 14,985 Instagram posts using machine learning algorithms and manual content analysis to identify how topics, sentiments, and Key Opinion Leaders (KOLs) evolve throughout various stages of the issue-attention. Regression models were em…
Living in the Trust Nexus
Citizens' trust in the news and the government can affect the success of governments' strategic intervention in the news media to advance their positions. To sustain healthy trust levels in both sources, it is important to ensure that they can enhance their subjective well‐being. Through a survey, this study puts forth a trust‐nexus framework examining how the interplay of government and media trust impacts well‐being in a liberal‐authoritarian m…
Examining media’s coverage of Covid-19 vaccines and social media sentiments on vaccine manufacturers’ stock prices
Introduction: The COVID-19 pandemic caused a widespread public health and financial crisis. The rapid vaccine development generated extensive discussions in both mainstream and social media, sparking optimism in the global financial markets. This study aims to explore the key themes from mainstream media's coverage of COVID-19 vaccines on Facebook and examine how public interactions and responses on Facebook to mainstream media's posts are associ…
Linking Pathways from Perceived Absolute and Comparative Risk to Colorectal Cancer Screening Intention
Digital media platforms are crucial in providing health information to the public, including learning about cancer prevention strategies. Although the Cognitive Mediation Model (CMM) is a sound theoretical framework for explaining the underpinning process of health knowledge acquisition, one important remaining gap is how individuals are motivated to process health information through different discussion-generated elaboration strategies. To bett…
Examining Covid-19 Tweet Diffusion Using an Integrated Social Amplification of Risk and Issue-Attention Cycle Framework
in our corpus of tweets across the issue-attention cycle. The negative binomial regression results showed that at the pre-problem stage, topics on President Trump, speculation of origins, and initiatives to fight COVID-19 by non-government entities were most likely to be amplified, underscoring the inherent politicization of COVID-19 and erosion of trust in governments from the start of the pandemic. We also found that while tweets with negative …
Examining Theoretical Frameworks and Antecedents of Health Apps and Wearables Use
The advancement of health apps and wearables has garnered substantial academic attention, particularly in examining why individuals decide to use or not use them. In response to the extensive body of research on this topic, we conducted a scoping review of 61 articles published from 2007 to 2022, aiming to examine the dominant theoretical frameworks and antecedents of health apps and wearables use. The findings demonstrated that the dominant theo…
Examining the roles of social media information exposure and seeking on Covid-19 vaccination through the S-O-R model
Examining the antecedents and health outcomes of health apps and wearables use
While health apps and wearables are often touted to promote individuals’ physical and mental health, a fundamental question that remains unanswered is how individuals from low socioeconomic status (SES) groups benefit from using these digital health technologies. This study draws upon two theoretical frameworks – an extended technology acceptance model and communication inequality to answer this research question. A nationally representative samp…
Toward an Extended Infodemiology Framework
This study aims to extend the infodemiology framework by postulating that effective use of digital data sources for cancer communication should consider four components: (a) content: key topics that people are concerned with, (b) congruence: how interest in cancer topics differ between public posts (i.e., tweets) and private web searches, (c) context: the influence of the information environment, and (d) information conduits. We compared tweets (…
Social media may hinder learning about science; social media's role in learning about Covid-19
Examining the Role of Distrust in Science and Social Media Use
Trust in scientific actors and institutions in the United States is at an all-time low. At the same time, studies show that people use social media for science information and become increasingly vulnerable to COVID-19-related misinformation. Yet, we do not know whether low levels of trust cause people to turn to social media in the first place. We argue that if people do not trust the scientific information provided by scientists, they are likel…

Perceived Information Distortion about Covid-19 Vaccination and Addictive Social Media Use among Social Media Users in Hong Kong
During the COVID-19 pandemic, distorted information about the COVID-19 vaccination is widely disseminated through social media. The present study examined the association between perceived information distortion about COVID-19 vaccination on social media, individuals' functional and critical literacy, and addictive social media use (SMU), as well as the moderating roles of functional and critical literacy in the association between perceived info…
Measuring What Matters
The ways in which we collect health and social data, particularly data on vulnerable and underprivileged populations, is enormously influential over the quality and content of science and health communication. Data absenteeism-the absence or limits of data on groups experiencing social vulnerability-is endemic; and as a result, inferences drawn from studies with absentee data are questionable. Reasons for data absenteeism include tendencies towar…

Toward Data Sense-Making in Digital Health Communication Research
The rapidly increasing volume of health data generated from digital technologies have ushered in an unprecedented opportunity for health research. Despite its promises, big data approaches in understanding human behavior often do not consider conceptual premises that provide meaning to social and behavioral data. In this paper, we update the definition of big data, and review different types and sources of health data that researchers need to gra…
We Need the Lens of Equity in Covid-19 Communication
providing fertile ground for the spread of information, misinformation and disinformation. With limited gatekeeping, an immense amount of unprocessed scientific information is being put forward to publics not trained in science. In this commentary, we offer some propositions on how disinformation on COVID-19 has become mainstreamed through social media's spiral of amplification and what role public communication has in an emergency from a lens of…
Negative emotions shape the diffusion of cancer tweets
Purpose Drawing on the cognitive-functional model of emotions and emotional contagion, the authors aim to examine the role of negative emotions in the diffusion of cancer tweets. Design/methodology/approach Using an integrated approach of social network and text analytics, the authors analyzed 142,883 cancer tweets from February to March 2018. The roles of negative emotions, emotional contagion, cancer themes and user influence on the diffusion o…
Explicating problematic social network sites use
The prevalence of social network sites (SNSs) has sparked a growing interest in understanding the development of problematic SNSs use among adolescents. Yet, this nascent area of research is marked by some deficiencies in existing theoretical paradigms. This article seeks to review the state of research in problematic SNSs use—broadly with a specific focus on adolescents—and identify key areas of research for future scholarly work. First, we summ…
Extending the Cognitive Mediation Model
This research—a pilot study on the cognitive mediation model (CMM) in Singapore—seeks to revisit and test the applicability of an extended CMM in the context of nanotechnology by examining perceived familiarity as a separate outcome variable in addition to factual knowledge. A cross-sectional survey was administered to a nationally representative sample of 719 adult Singaporeans. Results demonstrated partial support for the hypothesized CMM. Firs…
Social Network Sites, Friends, and Celebrities
This study applies the social comparison theory to examine the effects of adolescents' engagement in comparison with friends and celebrities on social network sites (SNSs) on (a) their body image dissatisfaction (BID) and (b) their drive to be thin (DT) or muscular (DM). The study also examines celebrity involvement as an antecedent of the outcome variables. Data were collected through a survey of 1,059 adolescents in Singapore. Regression analys…
Seeking Information About Climate Change
This study replicates and extends the planned risk information seeking model (PRISM) in the context of impersonal risk by incorporating media use as an antecedent of risk information seeking intention. Results indicate that the model applies equally well to Singaporeans’ climate change information seeking intention as it does in the context of personal health information, suggesting that the model is generalizable across different risk and cultur…
Communication and knowledge as motivators
As breast cancer is the most prevalent cancer among women in Singapore, encouraging them to engage in preventive measures becomes increasingly important. This study aims to take a closer look at the influence of attention to media, interpersonal communication, news elaboration, and knowledge on women’s (aged between 30 and 70) perceived risks of breast cancer and their intentions to engage in preventive measures in Singapore. Attention to media, …
