Understanding the Effects of News-Finds-Me Perception on Health Knowledge and Information Seeking During Public Health Crises.

News-finds-me (NFM) perception is a belief that, in the era of social media, individuals can remain adequately well-informed about current events even if they do not actively seek news. While it has been examined in the context of general and political news, NFM perception has not been explored in the context of other genres of news. Through an online survey involving 1,001 Singaporeans, with the Planned Risk Information Seeking Model, this study examines how NFM perception is related to information seeking and COVID-19 knowledge. An issue-specific NFM perception was also proposed and tested in order to determine whether NFM perception and its associated effects differ when operationalized as general news exposure or issue-specific news relating to COVID-19. The negative relationship between general NFM perception and knowledge and the mediating role of information seeking on social media in this relationship are detected. It is also found that when the NFM perception is issue-specific (i.e. COVID-NFM perception), information insufficiency and intentions of information seeking on social media fully mediated the relationship between NFM perception and knowledge. Theoretical and practical implications are discussed.

The Rise and Development of Public Health Communication.

Public health communication as a socio-cultural practice can trace its lineage to the dawn of human civilization and the earliest attempts to warn, educate and influence behaviors of individuals and communities facing public health problems. But public health communication in the sense that it is understood today required contemporaneous advancement and innovations in the allied disciplines of public health and social sciences as well as in the communication industries. This essay reviews a largely forgotten history of public health communication that coincides with the onset of the "modern era" of public health in the late 1800s and continues through the 1960s. Four key developments are identified as influential in the evolution of what eventually would come to be known as public health communication: (1) the early use of mass communication for public health campaigns, (2) the search for effects, (3) the search for explanation from interdisciplinary perspectives, and (4) the formal recognition of health communication as a distinct and valuable field of practice and research.

The Use of Social Networking Sites (SNSs) in Health Communication Campaigns: Review and Recommendations.

The past decade has witnessed a rapid increase in the use of Social Networking Sites (SNSs) in health communication campaigns seeking to achieve an ambitious range of health-related impacts. This article provides a review of 40 studies and research protocols, with a focus on two key factors that differentiate SNSs from more traditional health communication approaches of the past. The first is the potential dualism between message sender and receiver, in which receivers become receiver-sources who forward and amplify the content and reach of health messages. The second is the potential dualism between message and message impact, in which the act of forwarding and modifying messages by receiver-sources itself becomes a measure of message impact. Each of these dualisms has implications for the design and evaluation of contemporary health communication campaigns. The review concludes with a series of observations and recommendations for future health communication research.

Identifying Opinion Leaders to Promote Organ Donation on Social Media: Network Study.

BACKGROUND: In the recent years, social networking sites (SNSs, also called social media) have been adopted in organ donation campaigns, and recruiting opinion leaders for such campaigns has been found effective in promoting behavioral changes. OBJECTIVE: The aim of this paper was to focus on the dissemination of organ donation tweets on Weibo, the Chinese equivalent of Twitter, and to examine the opinion leadership in the retweet network of popular organ donation messages using social network analysis. It also aimed to investigate how personal and social attributes contribute to a user's opinion leadership on the topic of organ donation. METHODS: All messages about organ donation posted on Weibo from January 1, 2015 to December 31, 2015 were extracted using Python Web crawler. A retweet network with 505,047 nodes and 545,312 edges of the popular messages (n=206) was constructed and analyzed. The local and global opinion leaderships were measured using network metrics, and the roles of personal attributes, professional knowledge, and social positions in obtaining the opinion leadership were examined using general linear model. RESULTS: The findings revealed that personal attributes, professional knowledge, and social positions predicted individual's local opinion leadership in the retweet network of popular organ donation messages. Alternatively, personal attributes and social positions, but not professional knowledge, were significantly associated with global opinion leadership. CONCLUSIONS: The findings of this study indicate that health campaign designers may recruit peer leaders in SNS organ donation promotions to facilitate information sharing among the target audience. Users who are unverified, active, well connected, and experienced with information and communications technology (ICT) will accelerate the sharing of organ donation messages in the global environment. Medical professionals such as organ transplant surgeons who can wield a great amount of influence on their direct connections could also effectively participate in promoting organ donation on social media.

Cultural tightness-looseness and normative social influence in eight Asian countries: Associations of individual and collective norms with vaccination intentions.

RATIONALE: Countries worldwide faced the same public health crisis that required promoting the same health behavior-vaccinations-during the COVID-19 pandemic. Thus, scholars have a unique opportunity to test behavioral change theories across countries with different cultural backgrounds. OBJECTIVE: Employing the extended theory of social normative behavior, this study examines the influence of individual and collective norms on COVID-19 vaccination intention across eight Asian countries. We examine how cultural tightness-looseness, defined as the degree of a culture's emphasis on norms and tolerance of deviant behavior, shapes normative social influence on COVID-19 vaccination intention. METHODS: We conducted a multicountry online survey (N = 2676) of unvaccinated individuals in China, Indonesia, Japan, Malaysia, Singapore, South Korea, Thailand, and Vietnam in May and June 2021, when COVID-19 vaccination mandates had not yet been implemented in those countries. We conducted hierarchical regression analyses with interaction terms for the total sample and then re-categorizied the eight countries as either "tight" (n = 1102) or "loose" (n = 1574) to examine three-way interactions between individual norms, collective norms, and cultural tightness-looseness. RESULTS: Perceived injunctive norms exerted the strongest impact of all normative factors on vaccination intention. Collective injunctive norms' influence depended on both perceived injunctive and descriptive norms, which was larger when norms were lower (vs. higher). The interactive pattern between perceived and collective norms was more pronounced in countries with greater cultural tightness. CONCLUSION: Our findings reveal nuanced patterns of how individual and collective social norms influence health behavioral decisions, depending on the degree of cultural tightness-looseness.

A portrait of food and drink in commercial TV series.

This study examines the content and presentation of food and drink on fictional, commercial television. It provides the first comparison of food and drink consumption across different television program genres designated for different age groups. Data originated with a random sample of 50 taped episodes of children's shows, 50 episodes of "tween" programs (shows targeted for 9- to 14-year-olds), 40 episodes of afternoon soaps, and 50 episodes of prime time shows. The choice of TV series was based solely on the strength of Nielsen audience ratings. The study coded the foods for nutritional content and the drinks for alcoholic/nonalcoholic content, how they were used, and in what context. Findings indicate that foods were more commonly offered and consumed on children's shows, and that problematic foods (defined as oils, solid fats, and foods with added sugars) were significantly more prevalent in youth-oriented shows than in adult-oriented shows. Although there was only a negligible presence of alcohol on children's shows, the average hourly use of alcohol on the tween shows matched that of the adult programs; therefore, alcohol was as common in the shows directed at young audiences as in shows for adults. Negative outcomes were largely absent from food and drink behaviors on these TV series.

The contextual effects of gender norms, communication, and social capital on family planning behaviors in Uganda: a multilevel approach.

This study hypothesized a multilevel model to examine the contextual effects of gender norms, exposure to health-related radio programs, interpersonal communication, and social capital on family planning behavior in Uganda. The results of hierarchical linear modeling showed that all of the four variables were significant predictors of family planning behavior. The authors found that gender norms as a contextual factor significantly interacted with the individual-level perceived benefit. The significant cross-level interaction effect was also observed between individuals' interpersonal communication and contextual variation in listening to a health-related radio program. Practical implications for family planning communication campaigns are discussed.

Improving Psychosocial Well-Being of Older Adults Through Exergaming: The Moderation Effects of Intergenerational Communication and Age Cohorts.

OBJECTIVE: Exergaming is one way to foster social interaction among older adults and to improve their psychosocial well-being, which is a crucial component of healthy aging. This study examined how exergaming affects older adults' social anxiousness, sociability, and loneliness, and it further analyzed differences in the exergaming effects across different types of game play and between different aging cohorts. METHOD: A 2 (pre-test vs. post-test) × 2 (young-old vs. old-old) × 3 (play alone vs. play with elderly vs. play with youths) mixed quasi-experiment (N = 89) was conducted in Singapore, and three-way MANOVAs were executed. RESULTS: Results showed a significant three-way interaction effect among exergaming, play type, and age group on older adults' psychosocial well-being. There was a significant decline in social anxiousness and an increase in sociability for young-old participants playing with youths. The sociability improved significantly for old-old participants playing with their peers. There was also a significant decrease in loneliness after exergaming, but little differences were found across different play types or age groups. DISCUSSION: The findings made contributions to aging research and shed light on our understanding about how to foster social interaction among older adults and, thus, promote healthy and active aging.

Media exposure and smoking intention in adolescents: a moderated mediation analysis from a cultivation perspective.

The study tested a moderated mediation model to examine the mechanisms underlying the link between media exposure and adolescent smoking intention by utilizing a modification of cultivation theory. A total of 12,586 non-current smoker adolescents in California were included in the analysis. Results showed that media exposure was positively related to smoking intention via perceived prevalence of peer smoking when friend disapproval of cigarette use was low. This study contributes to a better understanding of the mechanisms regarding the media effects on smoking intention, but the findings should be interpreted with caution due to the small effect size.

Fear appeals for individuals in different stages of change: intended and unintended effects and implications on public health campaigns.

This study represents an initial attempt to examine the intended and unintended effects of fear appeals among individuals in different stages of change. Toward this end, a pilot study investigated the effects of fear appeals promoting skin cancer preventive behavior among college students. After being exposed to fear appeals, individuals who were in the precontemplation stage indicated a greater likelihood of thinking defensively and fatalistically regarding the facts on health risk than those who had intended to engage in or who had previously engaged in preventive behavior. Concurrently, after being exposed to fear appeals, those who were in the precontemplation stage reported less favorable attitudes toward message recommendations, weaker intentions to engage in recommended behavior, and less performance of preventive behavior than those who had contemplated or had previously engaged in preventive behavior. Implications of these results on future public health campaigns are discussed.

Guilt, fear, stigma and knowledge gaps: ethical issues in public health communication interventions.

Public health communication campaigns have been credited with helping raise awareness of risk from chronic illness and new infectious diseases and with helping promote the adoption of recommended treatment regimens. Yet many aspects of public health communication interventions have escaped the scrutiny of ethical discussions. With the transference of successful commercial marketing communication tactics to the realm of public health, consideration of ethical issues becomes an essential component in the development and application of public health strategies. Ethical issues in public health communication are explored as they relate to eight topics: 'targeting' and 'tailoring' public health messages to particular population segments; obtaining the equivalence of informed consent; the use of persuasive communication tactics; messages on responsibility and culpability; messages that apply to harm reduction; and three types of unintended adverse effects associated with public health communication activities that may label and stigmatise, expand social gaps, and promote health as a value. We suggest that an ethical analysis should be applied to each phase of the public health communication process in order to identify ethical dilemmas that may appear subtle, yet reflect important concerns regarding potential effects of public health communication interventions on individuals and society as a whole.

Optimistic bias and perceptions of bioterrorism in Michigan corporate spokespersons, fall 2001.

The notion that individuals believe that they are more likely than others to experience positive events and avoid negative ones is a well-documented phenomenon in the combined literatures of social psychology and health communication. The current study focuses on Michigan corporate spokespersons' perceptions of their company's risk and potential for optimistic bias. Beginning on September 10, 2001, and continuing through October 2001, telephone surveys were conducted by a professional survey research firm to assess spokespersons' awareness of and preparedness for a bioterrorism attack at their corporation, as well as to ascertain perceived self-risk relative to that of other, similar corporations. The results offer evidence of a robust optimistic bias, and provide an unusually timely snapshot of levels of corporate awareness of bioterrorism during a critical period of time in which the U.S. experienced its first anthrax attack.
