Factors Impacting Chinese Older Adults’ Intention to Prevent COVID-19 in the Post–COVID-19 Pandemic Era: Survey Study

Hovick et al [11] argued that personal perception factors, particularly in the face of risk, can further influence communication inequalities and should be considered. In particular, risk perception can influence information-seeking attitudes and outcomes by shaping affective responses [20]. When individuals perceive threats as serious, it triggers negative emotions, such as fear and anxiety, motivating them to seek and process information to mitigate those emotions [21].

A 4D Theoretical Framework for Measuring Topic-Specific Influence on Twitter: Development and Usability Study on Dietary Sodium Tweets

To address this gap, we reviewed existing measures of influence from literature to propose a consolidated framework capable of quantifying topic-specific influence on Twitter for public use. Many measures have been proposed to quantify influence on social media. Note that the definition of influence on social media is slightly different from the notion of influence in other interactions.

The Relationship Between Health Literacy, Knowledge, Fear, and COVID-19 Prevention Behavior in Different Age Groups: Cross-sectional Web-Based Study

The results of this study that health literacy, knowledge, and fear influence prevention behavior were similar to the previous studies. Health literacy was assessed using the CCHL, which was created to assess the public health literacy of the average citizen, and consists of higher-order communicative and critical health literacy rather than functional health literacy [25].

The Influence of Provaping “Gatewatchers” on the Dissemination of COVID-19 Misinformation on Twitter: Analysis of Twitter Discourse Regarding Nicotine and the COVID-19 Pandemic

Rather, the most influential users serve as “gatewatchers,” who lack absolute control over what passes through the gates but instead heavily influence whether information is channeled into high-traffic areas where it is likely to spread or low-traffic areas where its impact is diluted [28,29].

How Health Care Workers Wield Influence Through Twitter Hashtags: Retrospective Cross-sectional Study of the Gun Violence and COVID-19 Public Health Crises

How Health Care Workers Wield Influence Through Twitter Hashtags: Retrospective Cross-sectional Study of the Gun Violence and COVID-19 Public Health Crises

Additionally, the magnitude of the influence of tweets with health care–led hashtags is not characterized. Finally, our analysis did not account for the voice of patients and survivors, who have previously been shown to have a powerful role on Twitter. Historically, health care professionals play defining roles in social justice and public health movements. Health care–led hashtag campaigns are positive, actionable, and portray a united front in developing solutions to pressing public health issues.

Impact of Trump's Promotion of Unproven COVID-19 Treatments and Subsequent Internet Trends: Observational Study

Previous studies have shown that individuals with high influence (ie, individuals with large social capital or political power) [2] can affect public decisions and purchasing power [3]. Moreover, many of these individuals have the ability to affect content, sentiment, and public attention by using social media to disseminate information [4].
