Media Influence on Bystander Intervention for Health Protective Norms: The Integrative Model of Behavioral Prediction Perspective.

Drawing upon the Integrative Model of Behavioral Prediction (IM) and the Bystander Intervention Model, this study investigates the impact of media health information on individuals' intentions to address violations of health norms, specifically noncompliance with mask-wearing during the COVID-19 pandemic. Our survey results (n=1,426) indicate a positive correlation between seeking health information from the media and the intention to confront norm violators regarding mask-wearing. This correlation is mediated through three intermediary pathways: attitudes, normative beliefs, and perceived behavioral control. These discoveries address a previously unexplored area concerning pro-social health behaviors, bystander intervention, and contribute to the field of health communication by linking them to research on media influences. Combining media and peer interventions could lead to more effective health outcomes. The discussion covers both theoretical and practical implications.

Understanding Breast Cancer Images in Art History as a Form of Health Communication.

Can art and visual images meant for public consumption (museums, galleries, social media platforms) serve as a critical form of health communication for breast cancer patients? For their clinicians? For the population at large? Art history research methods are applied to a range of breast cancer images in western art in order to understand what the images communicate to us about patient experience, agency, and inequity in health care at the time of their construction. The following is a selective look at western art as it reflects and informs our understanding of breast cancer over time.

Public health communication professional development opportunities and alignment with core competencies: an environmental scan and content analysis. / Offres de perfectionnement professionnel en communication en santé publique et correspondance avec les compétences essentielles : analyse contextuelle et analyse de contenu.

INTRODUCTION: Communication is vital for effective and precise public health practice. The limited formal educational opportunities in health communication render professional development opportunities especially important. Competencies for public health communication describe the integrated knowledge, values, skills and behaviours required for practitioner and organizational performance. Many countries consider communication a core public health competency and use communication competencies in workforce planning and development. METHODS: We conducted an environmental scan and content analysis to determine the availability of public health communication professional development opportunities in Canada and the extent to which they support communication-related core competencies. Three relevant competency frameworks were used to assess the degree to which professional development offerings supported communication competency development. RESULTS: Overall, 45 professional development offerings were included: 16 "formalized offerings" (training opportunities such as courses, webinars, certificate programs) and 29 "materials and tools" (resources such as toolkits, guidebooks). The formalized offerings addressed 25% to 100% of the communication competencies, and the materials and tools addressed 67% to 100%. Addressing misinformation and disinformation, using current technology and communicating with diverse populations are areas in need of improved professional development. CONCLUSION: There is a significant gap in public health communication formalized offerings in Canada and many of the materials and tools are outdated. Public health communication professional development offerings lack coordination and do not provide comprehensive coverage across the communication competencies, limiting their utility to strengthen the public health workforce. More, and more comprehensive, professional development offerings are needed.

Meaningful Media Experiences and Vaccination Message Communication: An Experimental Study with Vaccine-Hesitant Individuals.

Guided by the eudaimonic media and the health persuasion literature, the current study explores how meaningful emotions elicited from entertainment media exposure decreases anti-vaccination attitudes among vaccine-hesitant individuals. Results of a between-subjects experiment (N = 409) showed that participants who viewed meaningful music videos (vs. neutral videos) and vaccination messages embedded in the user-generated comments reported more empathy, less reactance, and less anti-vaccination attitudes. Multigroup analysis revealed that this association was held for participants who were hesitant about whether they would get fully vaccinated, but not for participants who were determined to not get vaccinated. Theoretical and practical implications were discussed.

Exploring the Strategic Use of TikTok for Clinical Trial Recruitment: How audiences' Prior Short-Form Video Usage Influences Persuasive Effects.

Guided by the elaboration likelihood model and framing theory, this study explores the potential of short-form video platforms (e.g. TikTok), for targeted clinical trial recruitment. An online experiment compared doctor vs. peer-led videos addressing logistical or psychological barriers to participation, mimicking common TikTok communication tactics. Results indicate that high (vs. low) TikTok users are more persuaded by recruitment messages, and they exhibit stronger intentions to participate in clinical trials. Although doctor-sourced messages generate greater credibility and a more favorable message attitude, peer-sourced messages may be more effective in increasing participation intention. Lastly, doctor-sourced videos that address logistical barriers and peer-sourced videos that discuss psychological barriers result in higher self-efficacy for clinical trial participation. This study contributes to the growing body of research on new media's role in health communication and provides insights into how to strategically utilize TikTok and other short-form video platforms for clinical trial recruitment.

Which messages about healthy and sustainable eating resonate best with consumers with low socio-economic status?

Consumers with low socioeconomic status (SES) eat less healthy and sustainable diets than consumers with higher status. This is attributed, at least in part, to inequalities in health communication. An online survey with 134 socioeconomically disadvantaged consumers in Italy was conducted to test the effectiveness of tailor-made communication material (infographics) about healthy and sustainable eating (HSE). Participants were recruited at two social supermarkets by a social service organisation as well as via a crowdsourcing platform. Participants found information about HSE delivered through infographics moderately effective in increasing motivation, capability, and opportunity for HSE, and moderately useful and likely to impact their behaviour. Certain messages were more effective than others for native consumers, while migrants showed more indifferent responses to the various messages and manifested lower motivation to shift towards HSE, limited access to and seeking of nutrition-related information, and lower trust in information sources. Selecting which messages to deliver strategically, while also considering differences between segments of the target audience and their preferred sources and channels for communication, is promising; yet, structural changes related to food's affordability and availability are also needed to facilitate an effective communication.

Veterans' Exposure to News Portrayals of Military-Related Posttraumatic Stress and Support for Government Health Interventions: Influences of Stigma and Halo Communication.

This study interrogates the nature by which media perpetuates and potentially preempts stigma about military-related posttraumatic stress. Indeed, addressing the stigma of mental illness is critical to facilitating veteran comfort in seeking needed mental health care. Therefore, the authors explored how media messages about veterans experiencing posttraumatic stress (PTS) influenced how veterans viewed themselves, other veterans experiencing PTS and overall support for government policy and intervention. An experimental design was used to assess how veterans' perceptions are affected by messages adhering to the principles of the model of stigma communication, as well as its more prosocial counterpart, what the authors coin as halo communication. Findings reveal evidence that stigma messages more potently influence outcome perceptions relative to comparable halo messages in the current context. Additionally, interactive effects of message exposure (i.e. conditioned by perceived association with PTS identity) were observed on views that government health intervention is warranted for veterans managing PTS. Practical and theoretical implications are discussed.

Should Communication Campaigns Promoting Vaccination Address Misinformation Beliefs? Implications from a Nationally Representative Longitudinal Survey Study among U.S. Adults.

Public health communication campaign planners must carefully consider whether misinformation beliefs are important to target and, ideally, correct. Guided by the reasoned action approach, we hypothesized that behavior-specific beliefs regarding COVID-19 vaccination would account for any observed relationship between general coronavirus misinformation beliefs (misinformation beliefs that are not specific to the anticipated consequences of COVID-19 vaccination) and subsequent vaccine uptake. To test our hypothesis, we used panel data from a two-wave nationally representative sample of U.S. adults pre- and post-vaccine availability (T1: July 2020, T2: April/June 2021, analytic sample: n = 665). Contrary to our hypothesis, we find a residual observed relationship between general coronavirus misinformation beliefs and subsequent vaccine uptake (AOR = 0.40, SE = 0.10). Intriguingly, our post-hoc analyses do show that after also adjusting for T2 behavioral beliefs, this association was no longer significant. With this and other justifications, we recommend that messages promoting vaccination prioritize targeting relevant behavioral beliefs.

COVID-19 vaccination communication: Effects of vaccine conspiracy beliefs and message framing among black and white participants.

BACKGROUND: The importance of vaccination in combating the COVID-19 pandemic is widely acknowledged. The aim of this study was (1) to understand how one's vaccine conspiracy beliefs would influence their public health news processing, (2) to examine how specific public health news features (i.e., news frame) would influence message processing, and (3) to examine if there were any differences between Black and White participants in their message processing. METHODS: A nationwide online experiment (N = 821) with a 3 (vaccine conspiracy beliefs: high vs. moderate vs. low) × 2 (participants' race: Black vs. White) × 2 (news frames: gain vs. loss) mixed-factorial design was conducted in the United States. RESULTS: Participants' level of vaccine conspiracy beliefs was predictive of their responses to outcome measures. Additionally, Black participants reported higher perceived message effectiveness, more favorable attitudes toward the message, and higher vaccination intentions than White participants. Furthermore, health news that emphasized vaccination benefits produced more favorable attitudes than those emphasizing losses associated with non-vaccination, especially for White participants. Lastly, participants reported more favorable attitudes toward gain-framed health news regardless of their vaccine conspiracy beliefs. CONCLUSION: It is crucial for health officials to work to find effective media message strategies to combat COVID-19 vaccine conspiracy theories and misinformation. Furthermore, this study supports the significance of health organizations' ongoing efforts to tailor public health messaging to specific racial groups, as evidenced by considerable variations in perceptions among Black and White Americans.

Identifying promising themes and messages for youth vaping prevention: A national study.

Use of e-cigarettes and vapes among adolescents continues to be a major public health concern. Health communication efforts can discourage e-cigarette use among adolescents by influencing beliefs and behavior. However, to do so, studies need to identify the most promising themes and messages based on the latest evidence about the harms of e-cigarettes and vaping. Participants were a nationally representative sample of 1,603 US adolescents aged 13-17 years, recruited in the summer of 2022. Adolescents were randomly assigned to view 7 vaping prevention statements (one from each theme: nicotine addiction, chemical harms, health symptoms, mental health, organ effects, cosmetic effects, and monetary cost) and 1 control statement (vape litter theme) from a pool of 46 statements that were developed through a systematic process. Participants rated each statement on perceived message effectiveness (PME), awareness, and believability. Results of linear mixed models indicated that all vaping prevention themes out-performed control messages on PME, with chemical harms and organ effects having the largest effects, followed by nicotine addiction and then other themes. For most message themes, PME effects were stronger for youth susceptible to vaping compared to non-susceptible youth and users. Both awareness and believability predicted higher levels of PME. In secondary analyses, we found that statements specifying the target ("you") and longer statements were also rated higher on PME. Results suggests that the most potent vaping prevention messages for adolescents are those that focus on vape chemicals and the potential of vaping to damage organs and increase disease risk.

Mechanisms of mental illness anti-stigma messaging matter: Leveraging mental health communication inequities among Latinx populations to understand what works and what we can do better.

BACKGROUND: Since 1950, public communication about the neurobiological-psychosocial basis of mental illness from the diathesis-stress model has promoted reception to treatment yet violent/dangerous stereotypes have increased during this period. Moreover, public mental health communication efforts have predominantly diffused in English-language media, excluding Spanish/Latinx media and its consumers from these efforts. To inform future mental health communication strategies, this study leverages high versus low diffusion of public mental health communication across English and Spanish/Latinx media to examine public mental health communication effects on stigma and treatment beliefs via neurobiological-psychosocial beliefs. METHODS: A quota sample of 2058 U.S.-based Latinx residents ages 13-86 with diverse language/cultural media preferences was recruited to self-complete a survey about mental health information acquisition in 2021. Assessments ascertained frequency of Spanish/Latinx and English media use and mental health content scanning and seeking (α = 0.86-0.94); and items from the General Social Survey about mental illness neurobiological-psychosocial causal beliefs (α = 0.72)-genetics, brain chemistry, environment, stress; treatment beliefs-mental illness improves with treatment or on its own; and stigma beliefs-violent/dangerous and bad character stereotypes and unwillingness to socialize with a person with mental illness. Structural equation models estimated total, direct, and indirect effects of Spanish/Latinx and English media exposures on treatment and stigma beliefs via neurobiological-psychosocial beliefs, net individual/family factors. RESULTS: Spanish/Latinx media reduced, while English media increased, neurobiological-psychosocial beliefs (p < 0.01). Neurobiological-psychosocial beliefs, in turn, increased treatment and stigma beliefs (p < 0.01), simultaneously. Indirect pathways were also significant (p < 0.05). Proportion mediated on treatment beliefs was one-third for Spanish/Latinx and two-thirds for English media. Proportion mediated on stigma beliefs for all media exposures averaged ≥1. CONCLUSIONS: While consumers of Spanish/Latinx media report lower neurobiological-psychosocial knowledge that impedes treatment beliefs, consumers of English media report greater neurobiological-psychosocial and treatment knowledge and, consequently, more stigma. Innovation in public mental health communication is needed to counter stigma and health inequity.

US Nationwide Multi-City Media Coverage of COVID-19 Responses: Community Structure Theory, Belief System, and a "Violated Way of Life".

Community structure analysis compared city characteristics and newspaper coverage of state/local government responses to COVID-19 in 25 major U.S. cities, sampling all 250+ word articles from 4/4/20 to 7/6/20. The resulting 588 articles were coded for "prominence" and "direction" (favorable/unfavorable/balanced-neutral coverage), then combined into each newspaper's composite "Media Vector" (range=0.3552 to -0.5197, or 0.8749). Twenty-one of 25 newspapers (84%) displayed unfavorable coverage of local COVID-19 responses. Pearson correlations and regression analysis confirmed a muscular "violated way of life" pattern, when a community perceives itself as threatened by a "biological threat or a threat to a cherished way of life." Political and belief system polarization (in particular percent Evangelical and percent voting Republican) were strongly associated with unfavorable coverage of local pandemic responses, compared to more favorable responses linked to percent voting Democratic or percent Catholic. Vulnerability (percent uninsured) was also linked to negative coverage. Conversely, two different measures of access to healthcare (percent municipal spending on health and welfare, and physicians/100,000) were significantly linked to favorable coverage of the same local government efforts. Community structure theory's grass roots "bottom up" expectations linking community demographics to variations in reporting on critical issues were robustly confirmed.

Effects of message framing and risk perception on health communication for optimum cardiovascular disease primary prevention: a protocol for a multicenter randomized controlled study.

Background: Although several guidelines for cardiovascular disease (CVD) management have highlighted the significance of primary prevention, the execution and adherence to lifestyle modifications and preventive medication interventions are insufficient in everyday clinical practice. The utilization of effective risk communication can assist individuals in shaping their perception of CVD risk, motivating them to make lifestyle changes, and increasing their willingness to engage with preventive medication, ultimately reducing their CVD risks and potential future events. However, there is limited evidence available regarding the optimal format and content of CVD risk communication. Objective: The pilot study aims to elucidate the most effective risk communication strategy, utilizing message framing (gain-framed, loss-framed, or no-framed), for distinct subgroups of risk perception (under-perceived, over-perceived, and correctly-perceived CVD risk) through a multi-center randomized controlled trial design. Methods: A multi-center 3 × 3 factorial, observer-blinded experimental design was conducted. The participants will be assigned into three message-framing arms randomly in a 1:1:1 ratio and will receive an 8-week intervention online. Participants are aged 20-80 years old and have a 10-year risk of absolute CVD risk of at least 5% (moderate risk or above). We plan to enroll 240 participants based on the sample calculation. The primary outcome is the CVD prevention behaviors and CVD absolute risk value. Data collection will occur at baseline, post-intervention, and 3-month follow-up. Discussion: This experimental study will expect to determine the optimal matching strategy between risk perception subgroups and risk information format, and it has the potential to offer health providers in community or clinic settings a dependable and efficient health communication information template for conducting CVD risk management.Clinical trial registration: https://www.chictr.org.cn/bin/project/edit?pid=207811, ChiCTR2300076337.

How Do Gain-Loss Frames and Cultural Arguments Persuade? Designing Effective Messages to Weaken College Students' Binge-Drinking Intentions.

To design effective health messages, this study investigates the effects of gain-loss framing and relevant moderating effects in the context of college students' alcohol use. Specifically, based on an online experiment, we tested the moderation effects of message-sidedness and binge-drinking behaviors using a mediation model in which the association between gain-loss framing and behavioral intentions is mediated by attitudes toward binge-drinking. Four hundred thirty-four Korean college students participated in this study. Hayes' PROCESS Macro for SPSS was employed for the analysis. The results show that loss-framing significantly increased participants' unfavorable attitudes toward binge-drinking in the one-sided message condition. Moreover, attitudes toward binge-drinking were more significantly associated with behavioral intentions to binge-drink among heavy drinkers than among non-heavy drinkers. Our findings suggest important theoretical and practical implications for the development of message-framing strategies in health campaigns designed to prevent college students' binge-drinking in collectivistic societies where the cultural meaning of drinking extends beyond the individual realm to the larger social context.

Is Vaccination Approaching a Dangerous Tipping Point?

This Viewpoint discusses declining vaccination rates in the US, specifically against COVID-19, and the ways in which clinicians and the Food and Drug Administration can counter the current large volume of vaccine misinformation.

Sourcing UK COVID-19 News: An Analysis of Sourcing Patterns of 15 UK News Outlets Reporting on COVID-19 Across Facebook, Twitter, and Instagram.

How a health emergency is defined and presented through the news media matters for public understanding and health outcomes. Previous studies have endeavored to identify the patterns of news sourcing in crisis coverage, specifically the interplay between political sources and health expert sources, but yielded inconclusive results. This study analyses the types and roles of actors (those entities mentioned in a story) and sources cited in news coverage of COVID-19 by surveying social media posts published by 15 UK news outlets coverage across Facebook, Twitter, and Instagram between 1 January to December 31 2020. Overall, the findings show the prominence of political sources in UK news and that the most frequently named sources were representatives of the UK government. Moreover, when stories involved political actors, they were more likely to be given a voice as a source. This demonstrates how COVID-19 was a generalized crisis for the UK, which cascaded beyond health and into other economic, social, and cultural domains. The data show some variations in sourcing patterns between the different social media platforms. The analysis suggests that this may reflect the conventions of presenting news on each platform, with some tending toward the model of consensus by prioritizing political and government sources, and others contributing to a sphere of legitimate controversy by giving voice to a wider range of sources. This is distinctive and opens up the possibility for further research on how journalists adapt stories for social media and the consequences for public health communication.

An Exploratory Content Analysis of the Use of Health Communication Strategies and Presence of Objectification in Fitness Influencer Social Media Posts.

Health and fitness content intended to inspire people to live healthy lives (e.g. "fitspiration") has been linked to negative body image among girls and young women. Fitness influencers purport wanting to motivate healthy behaviors. This study seeks to examine the presence of strategies known to positively influence health behaviors (e.g. attitudes, self-efficacy) as well as of content known to have a negative influence (e.g. objectification) among fitness influencers. We conducted a content analysis (N = 441) of a random sample of one year of posts from four Instagram fitness influencers popular with girls and young women in the United States. The main analysis consisted of codes related to objectification, health promotion strategies, health-related content, and social engagement (i.e., likes). We found that fitness influencers included content that conveyed constructs previously found to positively influence health behaviors (e.g., attitudes and self-efficacy), but objectification was frequently present, in more than half of the posts. Additionally, we found that the presence of objectification in posts was negatively associated with likes, a form of social endorsement. We suggest health communicators aim to work in tandem with fitness influencers to include content that may motivate positive health behaviors and improve media literacy and that influencers aim to reduce the amount of objectifying content included in their posts. Our findings shed light on content being conveyed and possible insights into the negative effects associated with viewing such content.

Mapping breastfeeding and COVID-19 related content and engagement on Facebook: Results from an online social listening study.

ISSUE ADDRESSED: The COVID-19 pandemic has seen evidence and advice evolve quickly. Since the start of the pandemic there has been confusion and concern about breastfeeding and COVID-19, and advice for this group has at times been contradictory. The volume of information on social media has exacerbated this. This study aimed to understand breastfeeding-related COVID-19 information sharing on social media during the global and Australian vaccine roll-out. METHODS: The CrowdTangle platform was used to source data from December 2020 to December 2021. Posts were categorised to intent and source and mapped to a timeline of pandemic-related events and announcements. Descriptive analysis was used to understand data distribution patterns and qualitative analysis for post-intent. RESULTS: A total of 945 posts were included. Post-interactions ranged from 0 to 6500. Vaccine-related posts were the highest in number and increased over time. Non-profit organisations shared the highest number of posts (n = 241), but interactions were highest with personal and government accounts. Peaks in posts and interactions mapped to key pandemic-related announcements and events. CONCLUSION: These results describe the breastfeeding and COVID-19 related content shared on Facebook over 13 months, and the associated interactions. Breastfeeding is an important public health issue and breastfeeding women have experienced conflicting and confusing breastfeeding-related information during the COVID-19 pandemic. Better understanding of social media usage, and the monitoring of changes in usage, as an emergency unfolds, can help target communications. This article adds to the evidence in understanding user reactions to COVID-19 related breastfeeding information on social media. SO WHAT?: Social listening is an important part of health communication and infodemic management. Understanding how users react to and engage with COVID-19 related breastfeeding information on social media can help to understand how the general public perceives and responds to health advice and other information being shared.
