Social media promotion, risk perception, and parental support for adolescent girls' HPV vaccination: Taking consideration of future consequences and sexual attitudes as moderators.

HPV vaccine hesitancy in Asia is unique compared to western countries. Concerning whether social media promotion about HPV vaccine will be related with parental support for Chinese adolescent girls, we investigated the correlation among social media promotion, risk perception of HPV vaccine and parental support. Through the theoretical lens of Health Action Process Approach model (HAPA), we found that social media promotion could reduce the risk perception of HPV vaccine and promoted parental supportive decision, and risk perception played a mediation role between social media information exposure to vaccine and parental support. Consideration of future consequences has been found to play a moderating role between social media promotion and risk perception, and parents' sexual attitudes moderated the effect of social media promotion on parental support. Implications of the findings are discussed.

Social Media as Online Shelter: Psychological Relief in COVID-19 Pandemic Diaries.

The pandemic diary on social media is a special form of online communication. Studying individual narratives in social networks during the pandemic and post-pandemic periods can help us generate valuable knowledge about the behaviors of media users and the function of social media in a public health crisis. This research focuses on psychological relief in virtual public spaces and explores how social media individual narratives affect people's psychological health in a state of emergency from the perspective of narrative theory. Based on 19 in-depth interviews with Chinese diary writers, it has been found that the narrative genres of the pandemic diary were mainly Restitution and Quest narrative, while a few were categorized as "Restrained chaos" narrative. The purpose of editing pandemic diaries is to communicate both inwardly and outwardly. The pandemic diary can promote self-relief, public communication, emotional drive, meaning connection, and identity construction in public spaces, thus helping shape a sense of unity and belonging, and facilitating the psychological reconstruction of people who are vulnerable to potential mental health crises.

Exploring the Mediating Role of Situation Awareness and Crisis Emotions Between Social Media Use and COVID-19 Protective Behaviors: Cross-Sectional Study.

Background: In an outbreak of an infectious disease especially, online media would usually be an important channel for people to get first-hand knowledge and evaluate risks of the specific emergency. Although there has been increasing attention to the effect of social media use during epidemics and outbreaks, relatively little is known about the underlying mechanism by which social media plays a role in people's cognitive, affective and preventive responses. Objective: With an objective to advance current knowledge surrounding social media effects on people's cognition, affection and health protective behaviors during epidemics, we aim to examine the associations between social media exposure to COVID-19 risks related information and preventive behavior of the public, and also the role that situation awareness and crisis emotions including anxiety and fear played. Methods: An online cross-sectional survey was conducted in China a total of 632 participants were recruited. Measures included exposure to COVID-19 information through social media, situation awareness, anxiety, fear and protective behaviors that participants have taken. We have performed the descriptive statistical analysis, correlation and mediation analysis to test the research hypotheses. Results: Findings indicated that situation awareness was positively associated with social media use (B = 0.54, p < 0.001), anxiety (B = 0.95, p < 0.001) and fear (B = 0.87, p < 0.001), and preventive behavior (B = 0.68, p < 0.001). Social media use would also have an indirect effect on anxiety (indirect effect = 0.40; 95% CI = [0.34, 0.46]) and fear (indirect effect = 0.35; 95% CI = [0.29, 0.42]) through situation awareness. The serial mediation effect of situation awareness and fear in the correlation between social media use and preventive behavior has been testified (indirect effect = 0.04, 95% CI = [0.01, 0.08]). Conclusions: Social media use might influence the adoption of preventive behaviors through triggering situation awareness and fear. Therefore, health communication regarding COVID-19 prevention should target people with less internet access and low eHealth literacy. Understanding the positive role of negative crisis emotions during outbreaks could also help communicators and policymakers develop appropriate strategies to make people proactive to avoid the remaining health hazard.
