Scoping Review of COVID-19 Health Communication Research Authored by CHRC Student and Director

This article reports a scoping review of emerging research on COVID-19 health communication. We reviewed and analyzed 206 articles published in 40 peer-reviewed communication journals between January 2020 to April 2021. Our review identified key study characteristics and overall themes and trends in this rapidly expanding field of research. Our review of health communication scholarship during the early stages of the COVID-19 pandemic suggests that health communication scholars have risen to the challenges and interrogated important issues in COVID-19 communication at the individual, group, organizational, and societal levels. We identified important gaps that warrant future research attention including experimental research that seeks to test the causal effects of communication, studies that evaluate communication interventions in under-served populations, research on mental health challenges imposed by the pandemic, and investigations on the promise of emerging communication technologies for supporting pandemic mitigation efforts.

CHRC Assistant Co-Authors Study About COVID-19 Vaccine Twitter Discourse

Evidence-based health communication is crucial for facilitating vaccine-related knowledge and addressing vaccine hesitancy. To that end, it is important to understand the discourses about COVID-19 vaccination and attend to the publics’ emotions underlying those discourses. We collect tweets related to COVID-19 vaccines from March 2020 to March 2021. In total, 304,292 tweets from 134,015 users are collected. We conduct a Latent Dirichlet Allocation (LDA) modeling analysis and a sentiment analysis to analyze the discourse themes and sentiments. This study identifies seven themes of COVID-19 vaccine-related discourses. Vaccine advocacy (24.82%) is the most widely discussed topic about COVID-19 vaccines, followed by vaccine hesitancy (22.29%), vaccine rollout (12.99%), vaccine facts (12.61%), recognition for healthcare workers (12.47%), vaccine side effects (10.07%), and vaccine policies (4.75%). Trust is the most salient emotion associated with COVID-19 vaccine discourses, followed by anticipation, fear, joy, sadness, anger, surprise, and disgust. Among the seven topics, vaccine advocacy tweets are most likely to receive likes and comments, and vaccine fact tweets are most likely to receive retweets. When talking about vaccines, publics’ emotions are dominated by trust and anticipation, yet mixed with fear and sadness. Although tweets about vaccine hesitancy are prevalent on Twitter, those messages receive fewer likes and comments than vaccine advocacy messages. Over time, tweets about vaccine advocacy and vaccine facts become more dominant whereas tweets about vaccine hesitancy become less dominant among COVID-19 vaccine discourses, suggesting that publics become more confident about COVID-19 vaccines as they obtain more information.

CHRC Research Group Publishes Study on Visual Framing of Disasters

The present study seeks to systematically describe how humanitarian aid organizations use visuals in their natural disaster-related social media messages and to analyze their effects on social media engagement. Using Rodriguez and Dimitrova’s (2011) four levels of visual framing, we performed a content analysis of 810 tweets from 38 aid organizations. The results showed that, overall, the organizations’ visuals had an emphasis on victims and on disaster relief efforts. The most effective types of visual framing, however, were not those the aid organizations most commonly used. We discuss the theoretical and practical implications.

Sharing the stories of people whose lives are impacted by Opioid Use Disorders (OUDs) can be a promising strategy to reduce stigma and increase support for beneficial public policies. Since a story can be told from a first-person or third-person point of view (POV), this study sought to (1) determine the relative persuasive effects of narrative POV and (2) identify the underlying psychological mechanisms, including character identification and psychological reactance, of such narratives. A one-way between-subjects experiment was conducted among a college student sample (N = 276). Narrative POV was manipulated by describing a college student’s OUD experience from either the first- or third-person POV. Findings demonstrated that POV did not influence identification but had a significant effect on reactance. Specifically, the first-person (vs. third-person) POV narrative led to lower reactance, which was associated with participants’ decreased desire to socially distance themselves from people with OUDs and stronger support for public health-oriented policies regarding OUDs. This study sheds light on the mixed findings revealed in the literature and has practical importance in health message design in the current opioid epidemic.

CHRC Alum, Student, and Faculty Publish New Article in Mobile Media & Communication

Qin, Y., Wang, X., & Kang, N. (2021). A meta-analysis of the overall effect of mHealth physical activity interventions for weight loss and the moderating effect of behavioral change theories, techniques, and mobile technologies. Mobile Media & Communication, 20501579211054929

Mobile technologies offer the potential for efficacious and cost-effective lifestyle interventions for weight loss. Extant research indicates that mobile health (mHealth) lifestyle interventions are potentially effective and practical methods of weight loss, but it is less known what intervention characteristics are associated with weight loss effects. This meta-analysis examined the effectiveness of mHealth physical activity interventions for weight loss compared with non-technology/usual care interventions and the moderating effects of behavioral change theories, techniques, and mobile technologies. A total of 24 studies were identified based on inclusion criteria. Weight loss was the primary outcome. The results showed a medium significant effect size (d = 0.395; 95% CI= 0.243, 0.546; Z = 5.107, p < 0.001; N = 5146) favoring mHealth interventions. Interventions were significantly more effective when wearable devices were used (QB = 4.102, df = 1, p < 0.05) and when feedback was employed (QB = 4.566, df = 1, p < 0.05). The implications for future mHealth intervention design are discussed.

ABSTRACT
Research on health misinformation has grown rapidly as concerns about the potential harmful effects of health misinformation on individuals and society intensify amid a “post-truth” era. In this chapter, we provide a broad overview of current research and evidence concerning the many facets of health misinformation, including its sources, prevalence, characteristics (both content and diffusion features), impact, and mitigation. We conclude that health misinformation originates from many sources, most notably mass and social media; is fairly prevalent, both in interpersonal and mediated settings; and tends to feature negative sentiments, anecdotal evidence, and anti-science narratives. Although there is no conclusive evidence that health misinformation spreads more broadly than scientific information, health misinformation reliably leads to misperceptions on health issues. Efforts to mitigate the impact of health misinformation show early promise in correcting misperceptions. We offer several directions for future research.

ABSTRACT
Health literacy, commonly defined as the degree to which individuals can obtain, process, and understand health information, serves as an important determinant of healthy decisions and is central to the work of health communication researchers and practitioners. This chapter outlines the state of the field of health literacy: its definitions, models, measurements, and central debates at the intersection of health communication, medicine, and public health. The chapter includes an example of an applied intervention where a health literacy campaign was implemented in a community. It considers future research directions to position health communication scholars at the front lines of health literacy research, with the hopes of encouraging scholarship that inspires social change, community approaches, and attention to digital media contexts.
