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.

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.

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.

Lead Researcher: Jiyoun Kim

Summary: This project features experimental studies of online message processing for effective public communication and engagement in issues related to controversial (and sometimes unfamiliar) science and technology. As humans are by nature social animals, for example, this projects examines how social cues expressed in online content stimulate individuals’ cognitive processing and online news engagement intention. One of the goals of this project is empowering the public to make informed decisions. Since people’s rational responses could be impaired or interfered with by emotional arousal and/or mental agitation and most science- or health-related topics involve information under conditions of stress, this project seeks to understand what makes communication the most effective in situations of high concern or controversy.

Summary: The 2014 President’s Cancer Panel called underuse of HPV vaccines “a serious, but correctable threat to progress against cancer.” The Cancer Moonshot Blue Ribbon Panel, more recently, identified expanding the use of HPV vaccines as a top priority for cancer prevention, especially in medically underserved populations. Effective communication is crucial to widespread adoption of preventive measures against cancer like the HPV vaccines. Built upon recent advances in communication and behavioral sciences, the proposed project seeks to to develop and evaluate a novel, theory-based message framing intervention to accelerate HPV vaccine uptake among African American adolescents. This project aims to 1) develop culturally appropriate messages framed in gains and losses and pretest these messages through community engagement; 2) determine whether/how the effects of message framing (gain vs. loss) on African American parents’ acceptance of the HPV vaccine are moderated by their prior beliefs about HPV and the HPV vaccine; and 3) evaluate the efficacy of a message framing intervention rooted in message targeting principles through a clinic-based randomized trial. Addressing a critical aspect of health disparities disadvantaging the African American community, this research represents a systematic and timely effort to address the national urgency of optimizing communication strategies for promoting HPV vaccination among key stakeholders.

Summary: The overarching purpose of the proposed research is to harness new developments in psychological and communication sciences to address a key obstacle in communication-based smoking cessation efforts – the tendency for smokers to react defensively toward smoking risk information – and apply relevant knowledge to the promotion of smoking cessation among African American smokers. The proposed project seeks to evaluate an innovative approach based on self-affirmation theory to supressing smokers’ defensive processing of smoking risk information in a laboratory-based randomized trial involving African American smokers. Specifically, this project aims to 1) determine whether self-affirmation (vs. no self-affirmation) reduces defensive responses toward graphic cigarette warning labels; 2) ascertain whether self-affirmation (vs. no self-affirmation) leads to more negative explicit and implicit attitudes toward smoking, greater intentions to quit, and reduced cigarette consumption following exposure to graphic cigarette warning labels; and 3) investigate whether smoking identity moderates the effects of self-affirmation. The proposed project addresses a major public health concern as well as significant tobacco-related health disparities. This study will advance scientific knowledge on self-affirmation as a mechanism for reducing smokers’ defensive processing of smoking risk messages. The findings will be directly relevant to the translation of the basic behavioral science underlying smoking risk communication into enhanced smoking cessation approaches. If self-affirmation functions as expected in the proposed randomized trial, a self-affirmation task can be easily implemented in communication-based smoking cessation interventions to enhance the outcomes. The proposed study will also provide direct evidence relevant to the ongoing public health debate concerning the effectiveness of graphic warning labels as a means of communicating smoking risks in the United States.
