Motivating COVID-19 Vaccination through Persuasive Communication: A Systematic Review of Randomized Controlled Trials.

Vaccination is a vital defense against COVID-19 infections and outbreaks, yet vaccine hesitancy poses a significant threat to pandemic response and recovery. We conducted a systematic review of published randomized controlled trials ( = 47) assessing the persuasive effects of COVID-19 communication on COVID-19 vaccine acceptance. Individual vs.

Understanding the psychological antecedents of COVID-19 vaccine acceptance among Black Americans: implications for vaccine communication.

Background: Guided by the 5C (confidence, complacency, constraints, calculation, and collective responsibility) model of vaccination behavior, we examine the psychological antecedents of COVID-19 vaccine acceptance (i.e. attitudes and intentions toward COVID-19 vaccination) among Black Americans, a group disproportionately affected by the coronavirus pandemic.

Beliefs in COVID-19 Vaccine Misinformation Among Unvaccinated Black Americans: Prevalence, Socio-Psychological Predictors, and Consequences.

Health-related misinformation is a major threat to public health and particularly worrisome for populations experiencing health disparities. This study sets out to examine the prevalence, socio-psychological predictors, and consequences of beliefs in COVID-19 vaccine misinformation among unvaccinated Black Americans. We conducted an online national survey with Black Americans who had not been vaccinated against COVID-19 ( = 800) between February and March 2021.

Persuasive Effects of Temporal Framing in Health Messaging: A Meta-Analysis.

This meta-analysis investigated the persuasive effects of temporal framing in health messaging. Our analysis included 39 message pairs from 22 studies in 20 articles ( = 4,998) that examined the effects of temporal framing (i.e.

Moral Foundations Predict COVID-19 Vaccine Hesitancy: Evidence from a National Survey of Black Americans.

In this study we examine the role of moral values in predicting COVID-19 vaccine hesitancy among Black Americans. Guided by moral foundations theory, we assess the associations between six moral foundations (care, fairness, loyalty, authority, purity, liberty) and attitudes and intentions toward COVID-19 vaccination. Results of a national survey of Black Americans ( = 1,497) indicate that the care and loyalty moral foundations consistently predicted less vaccine hesitancy with overall more favorable attitudes and intentions toward COVID-19 vaccination, whereas the purity and liberty moral foundations were consistently associated with greater vaccine hesitancy.

Why do people believe health misinformation and who is at risk? A systematic review of individual differences in susceptibility to health misinformation.

Rationale: Health misinformation poses a significant threat to public health. Understanding why people believe health misinformation and who is at risk is crucial for developing effective interventions to reduce the harmful impact of misinformation.

Approach: We conducted a systematic review of published empirical research that examined individual differences in susceptibility to health misinformation, focusing on the psychological, demographic, and behavioral correlates of health misinformation susceptibility.

Public Perceptions of Food Contamination Risks: A Simulation Experiment on the Psychological Impact of Incident Severity and Intentionality.

How do consumers perceive risks associated with food contamination? How do they respond to foodborne illness outbreaks and food recalls resulting from food contamination? We report findings from an experiment ( = 1,010) in which participants were exposed to a simulated news report on a food contamination incident that had led to a foodborne illness outbreak and voluntary food recalls. Two characteristics of the food contamination incident were experimentally manipulated - severity (i.e.

A Scoping Review of Emerging COVID-19 Health Communication Research in Communication and Media Journals.

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.

Public Health Messaging during the COVID-19 Pandemic and Beyond: Lessons from Communication Science.

The COVID-19 pandemic has made it clear that effective public health messaging is an indispensable component of a robust pandemic response system. In this article, we review decades of research from the interdisciplinary field of communication science and provide evidence-based recommendations for COVID-19 public health messaging. We take a principled approach by systematically examining the communication process, focusing on decisions about what to say in a message (i.

African American Parents' Perceived Vaccine Efficacy Moderates the Effect of Message Framing on Psychological Reactance to HPV Vaccine Advocacy.

This experiment assessed how the frame of promotional vaccine messages elicited psychological reactance differently for African American parents according to their level of perceived vaccine efficacy. We found that those with low perceived HPV vaccine efficacy experienced more psychological reactance in response to loss-framed messages compared to gain-framed messages, whereas message framing made little difference for those with high perceived HPV vaccine efficacy. In addition, the interaction between frame and perceived HPV vaccine efficacy indirectly affected parents' intentions to vaccinate their child for HPV via reactance.

General and health-related social media use among adults with children in the household: Findings from a national survey in the United States.

Objective: Examine predictors of social media use among a nationally representative sample of adults with children in the household.

Methods: Data were collected from the Health Information National Trends (HINTS) Survey from 2017 to 2020 (N = 3559). Multivariate logistic regression models assessed the association between sociodemographic variables and social networking site (SNS) use, SNS use to share health information, participation in online forum or support groups for health issues and watching health-related videos on YouTube.

Self-Affirmation Does Not Change Smokers' Explicit or Implicit Attitudes toward Smoking Following Exposure to Graphic Cigarette Warning Labels.

Self-affirmation has shown promise in promoting pro-health attitudes following exposure to threatening health messages by reducing defensive processing of such messages. We examine the impact of self-affirmation prior to viewing graphic cigarette warning labels on implicit and explicit attitudes toward smoking in a sample of African American smokers ( = 151). Participants held negative explicit and implicit attitudes toward smoking.

Human Papillomavirus Vaccine Acceptability and Campaign Message Preferences Among African American Parents: a Qualitative Study.

Human papillomavirus (HPV) vaccination can prevent numerous cancers, yet uptake remains low for adolescents. Given disproportionate burden of cancers among African Americans, it is important to identify factors that influence HPV vaccination decisions among African American parents, specifically the role and preferences of vaccine campaign messages. The objectives of this study were to (1) identify the predictors of parents' decisions to get their children vaccinated against HPV, (2) assess parents' evaluation of current HPV vaccination campaign messages, and (3) uncover message strategies or themes parents consider to be effective and motivating to vaccinate their children against HPV.

Impact of Self-Affirmation on Responses to Health Warning Messages: Does Consideration of Future Consequences Matter?

Self-affirmation theory has inspired numerous studies that have tried to understand the effects of self-affirmation on defensive processing of threatening health messages and subsequent behavior. Despite the overall positive effects of self-affirmation, psychological processes through which self-affirmation exerts such impact remain unclear. We examined Consideration of Future Consequences (CFC) as a potential moderator of the effects of self-affirmation on responses to graphic cigarette warning warnings, in an attempt to shed light on the psychological processes.

Influence of Risk Severity and Intentionality on Perceptions of Food Contamination Risks among Pregnant Women: An Experimental Investigation.

Given the potential for severe health consequences of consuming contaminated foods during pregnancy, effective communication of food contamination risks to pregnant women is especially important. This study examines pregnant women's risk perceptions and intentions to adopt risk-reduction behaviors following exposure to a simulated news story about a food contamination incident. The news story was experimentally manipulated to depict the severity of the incident as high or low and the cause of the incident as accidental or intentional.

HPV Vaccine Searches on Pinterest: Before and After Pinterest's Actions to Moderate Content.

To compare how human papillomavirus (HPV) vaccination was portrayed on Pinterest before and after the platform acted to moderate vaccine-related search results to understand (1) what the information environment looked like previously and (2) whether Pinterest's policy decisions improved this environment in terms of sources and content. In this quantitative content analysis, we compared 2 samples of 500 HPV vaccine-focused Pinterest posts ("pins") collected before and after Pinterest's actions to provide more reliable vaccine-related information. Pins were based on search results and were analyzed using the Health Belief Model.

Self-Affirmation Moderates Self-Congruency Effect in Health Messaging.

Previous research found that health risk messages framed to be congruent with people's independent or interdependent self-construal were not consistently more effective than incongruent messages. We argue that people potentially process the self-construal congruent health risk messages in a biased manner. To test this proposition, we examined the role of self-affirmation, which is expected to reduce defensive processing, in college nonsmokers' responses to an antismoking message congruent vs.

Investigating the Interplay of Self-Construal and Independent Vs. Interdependent Self-Affirmation.

This study examines how the relative effects of independent and interdependent self-affirmation might be influenced by individuals' self-construal. A controlled experiment involving 186 Chinese adult smokers revealed a significant interactive effect of self-affirmation type and self-construal on message derogation and posttest attitudes toward smoking. For individuals with a dominant independent self-construal, independent self-affirmation (i.

Soda or VitaSoda: How Product Name Influences Perceptions of Snack Food Healthfulness and the Moderating Role of Nutrition Facts Labels.

Many parts of a food package label can influence consumers' product judgments. In this study we investigate how strategic product naming influences consumers' perceptions of snack food products' healthfulness and nutritional content by focusing on snack food names that include (versus do not include) the noun "vita." We also analyze how the effects of product naming are moderated by viewing the Nutrition Facts labels (NFLs).

How Thinking about the Future Affects Our Decisions in the Present: Effects of Time Orientation and Episodic Future Thinking on Responses to Health Warning Messages.

Past research has consistently shown that people have the tendency to discount future outcomes. However, most health messages emphasize the long-term consequences of behaviors. Building upon past research on temporal discounting, time orientation, and construal level, the current research examines how dispositional time orientation (present and future) predicts health behavior intentions and the impact of situationally-activated future orientation through episodic future thinking on the persuasiveness of long-term health warnings.

The role of trust in health information from medical authorities in accepting the HPV vaccine among African American parents.

This research examines how and why trust in health information from medical authorities (i.e., doctors or health care professionals and government health agencies) predicts acceptance of the HPV vaccine for one's child among African American parents.

Influence of Norm-Based Messages on College Students' Binge Drinking Intentions: Considering Norm Type, Regulatory Mode, and Level of Alcohol Consumption.

This study examined the influence of norm-based messages on U.S. college students' binge drinking intentions, focusing on norm type, locomotion and assessment regulatory modes, and level of alcohol consumption as possible moderators.
