Health controversies involve complex exchanges of disagreements over health and medicine. They unfold differently in different parts of the world, and they often extend over long periods of time. In contemporary argumentation theory, proposals have recently been emerging for "disagreement management at large scale" and for an explicit focus on design of disagreement management methods. Lewiński and Aakhus characterize large-scale disagreement as polylogic: formed of complex networks of players holding contrasting positions that are attacked and defended in multiple places. Large-scale disagreements such as health controversies are important sites for emergence of new disagreement management methods, including new ways of arriving at conclusions about questions of fact (affecting positions) and new formats for coming to decisions about questions of policy (affecting places). The controversy over myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), spanning a period of very rapid change in reasoning about health, has been deeply entangled with the design of new institutional places for managing disagreements about health. It serves well to illustrate both the large, multi-scale structure of health controversies and the importance of long-term disagreement management strategies.

Public health campaigns addressing COVID-19 vaccination beliefs may be effective in changing COVID-19 vaccination behaviors, particularly among people who remain vaccine hesitant. The "We Can Do This" COVID-19 public education campaign (the Campaign) was designed to increase COVID-19 vaccine confidence and uptake. This study aims to evaluate whether Campaign dose was associated with changes in vaccination beliefs related to COVID-19 vaccine concerns and perceived risks, the importance of COVID-19 vaccines, the perceived benefits of COVID-19 vaccination, normative beliefs about COVID-19 vaccination, and perceptions about general vaccine safety and effectiveness. The study linked data from four waves of a nationally representative longitudinal panel of U.S. adults (January 2021-March 2022) with Campaign paid digital media data (April 2021-May 2022). We used mixed-effects linear regressions to examine the association between Campaign paid digital impressions and changes in vaccination beliefs. The results provide evidence that Campaign digital impressions were significantly associated with changes in respondent beliefs regarding COVID-19 vaccine concerns and perceived risks, perceived benefits of COVID-19 vaccination, and perceptions about general vaccine safety and effectiveness. Findings suggest that public education campaigns may influence vaccine confidence and uptake by increasing positive vaccination beliefs and reducing vaccine concerns.

While pre-exposure prophylaxis (PrEP) has demonstrated efficacy in preventing HIV transmission, disparities in access persist in the United States, especially among Hispanic/Latinx sexual minority men (SMM). Language barriers and differences in how Latinx SMM obtain information may impact access to PrEP and HIV prevention. This study used data from the 2021 American Men's Internet Survey (AMIS) to examine differences in communication networks and PrEP use among Latinx SMM by primary language (Spanish vs. English). We examined the associations between Latinx SMM's individual- and meso-level communication networks and PrEP-related outcomes using modified Poisson regression with robust variances. Spanish-speaking Latinx SMM in the study were less likely to test for HIV, be aware of PrEP, and use daily PrEP, compared to English-speaking participants. Sexuality disclosure to a healthcare provider was positively associated with PrEP uptake among all participants and predicted STI testing over the past 12 months among English-speaking Latinx SMM. Findings highlight disparities in PrEP awareness and uptake among Latinx SMM, especially among those whose primary language is Spanish. Addressing these disparities through targeted interventions, including improved communication with healthcare providers, may help facilitate PrEP access and use in this population.

Asian, Pacific Islander, African, and Caribbean communities in the U.S. are heavily impacted by chronic hepatitis B (HBV) and hepatocellular carcinoma (HCC). Educating these groups about the link between the two diseases is imperative to improve screening rates and health outcomes. This study aims to identify and incorporate preferred mediated communication methods into community-specific educational campaigns which emphasize the connection between the conditions, to promote uptake of prevention and management behaviors for HBV and HCC. Fifteen focus groups and two key informant interviews were conducted with Micronesian, Chinese, Hmong, Nigerian, Ghanaian, Vietnamese, Korean, Somali, Ethiopian, Filipino, Haitian, and Francophone West African communities. Data were analyzed using thematic coding and analysis. Findings demonstrate that all communities preferred materials be offered in both English and native languages and requested that materials highlight the connection between HBV and HCC. Delivery channel preferences and messaging themes varied by group. This study provides insight into community-specific preferences for learning about HBV and HCC. The findings can be used to design culturally and linguistically tailored, multi-platform, health education campaigns to facilitate improved HBV screening and vaccination rates and increase knowledge about HCC risk among highly impacted communities in the U.S.

This study examines perceived source credibility of health information in a moment of TGD health disinformation. Through thematic analysis of in-depth interviews with 30 transgender and gender diverse (TGD) individuals, findings suggest health information is marred by anti-TGD legislation, a sociopolitical force that bleeds into health information spaces. Disinformation and TGD health communication are intertwined in complex ways, whereby disinformation can undermine trust in healthcare institutions, lead to harmful behaviors, and contribute to the spread of diseases. Health communication practitioners need to center the safety and humanity of TGD people, addressing TGD health disinformation.

This study investigated how the online health information behaviors of U.S. adults with illnesses unrelated to COVID-19 virus infection affected their coping with health problems and concerns during the COVID-19 pandemic. Guided by the cybercoping model (Kim & Lee, 2014), the study examined associations between these patients' online information behaviors (information seeking and information forwarding) and coping outcomes (health problems and affective states). The study further explored the mediating roles of health coping processes (problem-and emotion-focused) in the associations between these information behaviors and coping outcomes. Survey data from 687 participants were analyzed using structural equation modeling. The results highlighted the significance of information forwarding in enhancing both coping processes and outcomes, while information seeking enhanced problem-focused coping and health-problem coping outcomes alone. These associations were more pronounced among U.S. adults without chronic conditions than among those with chronic illnesses. These findings' implications, the study's limitations, and suggestions for future research were also addressed.

While research on youth vaping prevention has begun to grow, little work has examined language choice in vaping prevention messages. This study examined adolescents' responses to vaping prevention statements that varied on three features: behavioral framing, linguistic certainty, and target specification. We conducted a 2 (behavioral framing) by 2 (linguistic certainty) by 2 (target specification) by 3 (risk type) plus control condition between-subjects experiment using a national probability sample. Adolescents (N = 1,603) were randomly assigned to one of 25 conditions in which they viewed a vaping prevention statement (or a control statement about vape litter) followed by measures of perceived message effectiveness (PME), perceived severity and susceptibility of vaping risks, message trustworthiness, message relevance, and intentions to seek more information about vaping risks. Results showed main effects of behavioral framing, such that a declarative frame ("Vaping can … ") led to higher PME, higher perceived severity, and greater information seeking intentions than a contingent frame ("If you vape, it can…"), while an interaction revealed that most declarative frame effects were driven by adolescents who were susceptible to vaping. There were also main effects of linguistic certainty, such that the word "can" ("Vaping can … ") led to higher PME, higher perceived susceptibility and severity, and greater information seeking intentions than the word "could" ("Vaping could … "). No main effect of target specification ("you" vs. "teens") was observed. Overall, findings suggest that vaping prevention messages that communicate greater certainty have greater behavior change potential.

Per- and polyfluorinated substances (PFAS) contamination is an emerging environmental and health risk facing the world. This study examines the impact of conflicting information on Americans' attitude toward PFAS regulation and intention to engage in mitigation behaviors through a one-way, between-subjects experiment. Participants were 1,062 U.S. adults recruited from CloudResearch. Results showed that compared to participants exposed to consistent information, those exposed to conflicting information displayed less favorable attitude toward existing regulation, which led to lower intention to support related policies and to engage in mitigation behaviors. Political ideology moderated these relationships, with stronger experimental effects among conservatives. These findings underscore the importance of conveying consistent risk messages, especially when multiple stakeholders are involved.

Masspersonal communication has emerged as a compelling alternative persuasive approach in response to the widespread use of social media. It is crucial to comprehend how observing online interpersonal interactions regarding the fear appeal of climate change can foster pro-environmental behaviors among users. This study examines the effects of vicarious message interactivity in promoting actions against climate change and the underlying mechanisms behind this effect. The results of an online experiment conducted in China (N = 236) revealed that psychological reactance and message elaboration mediated the effects of vicarious message interactivity on behavioral intention in a serial indirect effect. In comparison to static fear appeal, interactive fear appeal proves effective in reducing psychological reactance, promoting message elaboration, and ultimately increasing intention to take actions against climate change. Our findings not only contribute to the literature on interactive communication but also provide insights for environmental-health campaigns on social media.

Over the past sixty years, scientists have been warning about climate change and its impacts on human health, but evidence suggests that many may not be heeding these concerns. This raises the question of whether new communication approaches are needed to overcome the unique challenges of communicating what people can do to slow or reverse climate change. To better elucidate the challenges of communicating about the links between human activity, climate change and its effects, and identify potential solutions, we developed a systems map of the factors and processes involved based on systems mapping sessions with climate change and communication experts. The systems map revealed 27 communication challenges such as "Limited information on how individual actions contribute to collective human activity," "Limited information on how present activity leads to long-term effects," and "Difficult to represent and communicate complex relationships." The systems map also revealed several themes among the identified challenges that exist in communicating about climate change, including a lack of available data and integrated databases, climate change disciplines working in silos, a need for a lexicon that is easily understood by the public, and the need for new communication strategies to describe processes that take time to manifest.
