This study explored how online media consumption, fear, mental wellbeing, and behavioral compliance with COVID-19 measures were related to one another during the COVID-19 pandemic. Employing a four-wave longitudinal survey research design (n = 1,092), this study found positive relationships between online media consumption and fear of COVID-19, between fear of COVID-19 and behavioral compliance, and between behavioral compliance and mental wellbeing in the general Dutch population. Results showed a negative relationship between fear of COVID-19 and mental wellbeing. Repeated measures ANOVAs indicated that participants' online media consumption, fear of COVID-19, and behavioral compliance with COVID-19 measures all gradually decreased as the pandemic progressed, while mental wellbeing gradually recovered as the pandemic progressed. Recognizing the negative relationship between fear of COVID-19 and mental wellbeing, policymakers may be encouraged to focus on implementing interventions and communication strategies to support mental health during pandemics. Using other types of appeals (e.g. hope appeals) in addition to the commonly used fear appeals when developing online public health messages could ensure behavioral compliance during pandemics without triggering high levels of fear. This can contribute to maintaining people's mental wellbeing when they have to cope with life-threatening public health crises while still promoting behavioral compliance with necessary public health measures.

This paper examines the efficacy of different messaging formats in the context of public health crises and emergencies in rural context. By analyzing usage statistics and user feedback, we assessed the effectiveness of various technology-mediated COVID-19 audio message formats (songs, expert interviews, endorsements, and dramas) delivered using the Amplio Talking Book device to rural communities in Ghana during the COVID-19 pandemic. Our findings indicate that different messaging formats resulted in varying levels of user engagement and interest. Shorter audio messages (1-5 minutes), and endorsements from credible and familiar community stakeholder significantly fostered trust and adoption. Establishing a consistent user feedback loop was essential for providing clarifications, addressing queries, and diffusing disinformation and misinformation, especially considering the unprecedented nature of the COVID-19 outbreak. Reflecting on these insights, we discuss effective strategies for creating engaging technology-mediated public health and behavior change messages during public health crises.

When stories have undesirable endings, readers often engage in replotting, meaning they imagine alternative plotlines that could change the unwanted ending. Recent research has found that both the cognitive and emotional components of replotting serve as mechanisms of narrative persuasion. Building on this work, the current study assessed if people who habitually replot are more persuaded by a tragic story ending than those who do not, testing hypotheses with melanoma narratives. Cognitive and emotional (i.e., anger, anxiety, sadness, and hope) aspects of replotting were tested as mechanisms of this proposed interaction. Participants (N = 432) were randomized into a 2 (protagonist death vs. survival) x 6 (specific melanoma story) between-subjects online narrative message experiment. Participants who habitually replot had significantly higher melanoma prevention intentions after reading a death (compared to a survival) ending. This effect was not present for other participants. However, counter to hypotheses, the cognitive and emotional aspects of actual replotting did not explain the effect, meaning habitual replotters were not more likely to replot the death ending or experience replotting emotion than other participants were. Future research is needed to determine why habitual replotters are more persuaded by unwanted story endings than other audience members are.

Media coverage of depression on social media with specific framings could shape people's perception and attitude, which is significant in reducing the stigma and promoting support for depression sufferers. Adopting the lens of moral foundation theory (MFT), this study aims to explore the effect of inherent moral framings within depression coverage on social media on the stigma and approval attitudes toward depression in audiences' responses. A large language model and a dictionary-based approach were respectively adopted to score depression-related media coverages (n = 919) and corresponding comments (n = 92,505) collected from the Weibo platform against MFT's five dimensions and (de)stigma attitudes. The results indicated that care, purity, and fairness framings are prevalent in depression coverage, surpassing moral framings such as betrayal, harm, and cheating. Most responses expressed approval rather than stigma. Moreover, the use of care and loyalty framings can elicit approval responses but decrease audience engagement.

In a secondary analysis, we examine how trust in pro-recommendation versus alternative communication channels mediated effects of demographic, personality, lifestyle, and political variables on COVID-19 protective behavior in England. In so doing, we adapt the media-as-mediator approach to the pandemic context. Respondents reported that family, close friends, primary care medical providers, and mainstream news media were relatively supportive of public health recommendations, and social media friend networks, faith/community groups, alternative news sites, and alternative health practitioners were relatively unsupportive. Parallel mediation analyses showed that effects of age, dutiful civic-mindedness, sensation-seeking, healthy lifestyle orientation, and more marginally, race on COVID-19 protective behavior were mediated by trust in these pro-recommendation and/or alternative communication channels. In some cases, trust in exemplars of both types of channels resulted in these channels influences largely canceling one another out.

With COVID-19 vaccination rates remaining below optimal levels, scalable interventions to shift vaccination intentions are needed. We embedded two randomized experiments in South Africa's COVID-19 Vaccine Survey (CVACS) to investigate the potential to change vaccine intentions and behavior. In Experiment 1, 3510 unvaccinated South African adults were randomly assigned to a no-message control group, a social norm message, or a message highlighting that vaccines were free, available and easy to obtain. The free and easy message significantly increased vaccine intentions but did not increase other outcome measures. The social proof message was associated with an increase in self-reported vaccination status at follow-up (not significant at traditional statistical thresholds). In Experiment 2, 3608 unvaccinated South African adults were randomly assigned to a no-message control group, a message highlighting gaining greater freedoms, or a message highlighting being part of the solution to the pandemic. Neither value proposition message increased vaccination intentions. Light-touch and scalable messages informed by behavioral science and social marketing principles may increase vaccination intentions and uptake, However, more attention should be paid to understanding the behavioral barriers experienced by different population segments, and to tailoring and targeting messaging to those barriers and segments.

Young people account for over half of new STI cases and youth of color face increased sexual health disparities. In partnership with Fact Forward, researchers conducted qualitative formative audience research to develop a culture-centered health communication campaign to increase access to and use of sexual health services among youth of color in South Carolina. Grounded in a reproductive justice theoretical framework, this study employed innovative strategies, including training youth ambassadors to moderate peer-to-peer focus groups. A total of 134 participants were recruited for the study with 51 individuals participating in 9 focus groups and 83 respondents completing a web-based survey (ages 15-24). Qualitative data analyses used Nvivo 1.5.1. Statistical analyses used R Studio®. Findings revealed barriers including lack of education about risks. Participants identified dimensions of inequity and the importance of intersectional messaging to address intimacy, sexuality, and trust. They emphasized normalizing conversations about sexual health and the need for important others "in your corner" to provide support. Participants suggested an empowering storytelling approach to reduce shame surrounding sexual health services. Social media emerged as an optimal communication channel. UNC Perceived Message Effectiveness (PME) Scale scores ranged from 4.42 to 4.57 (out of 5) indicating that messages were well received by participants. Sex-positive campaign messaging focused on self-love, empowerment, and taking control of sexual health. This study offers practical suggestions to develop effective communication strategies to reach youth of color to increase use of sexual health services, including contraceptive counseling, STI prevention, screening, and treatment.

To examine the effects of numerical evidence and message framing in communicating vaccine efficacy information about infectious diseases, an online experiment presented to U.S. adults different versions of a vaccination promotional message that vary by numerical vaccine efficacy evidence: (low efficacy rate: 60% vs. high efficacy rate: 95%), outcome framing (preventing disease-related infection vs. preventing disease-related severe illness), and gain vs. loss framing, using a factorial between-subjects design. While there was no significant interaction between numerical vaccine efficacy evidence and message framing, findings showed that a higher vaccine efficacy rate increased positive beliefs about vaccination and outcome framing emphasizing infection prevention increased message processing fluency. Given that infectious diseases pose higher risks for severe illness among older adults, follow-up analyses by age showed that only younger adults were sensitive to message framing where outcome framing emphasizing infection prevention increased processing fluency.

Our team developed Conversation Cards for Adolescents© (CCAs), a tool to help adolescents and health care providers (HCPs) communicate and collaboratively set behavior change goals. The objectives of this pilot randomized controlled trial were to test the feasibility, user experience, and preliminary effect of using CCAs with adolescents in primary care, focusing on behavior change and collaborative goal setting among adolescents. From March 2019 to September 2022, adolescents were recruited from the Northeast Community Health Centre (Edmonton, AB). Adolescents were randomized (1:1) to one of two groups: CCA + goal setting (experimental group) or goal setting alone (control group). Data were collected from both groups at baseline and at 3-weeks post-baseline. In total, 31 adolescents completed the trial (terminated early due to COVID-19). The study demonstrated high practicality. Adolescents reported positive user experiences with CCAs, citing attractiveness, clarity, efficiency, and dependability. No group differences were detected for behavior changes at 3-weeks post-baseline (p > .05), although adolescents in the experimental group qualitatively described improved rapport and communication with HCPs. CCAs can be used practically in a primary health care setting to facilitate communication and rapport with adolescents; however, their effect in enabling behavior change should be investigated in a multi-site, larger-scale trial.

The current study investigated the effectiveness of factual and narrative messages in promoting advocacy intentions among viewers of COVID-19 vaccination messaging. In an online posttest only experiment on Qualtrics online software, participants (N = 323) were randomly assigned to one of four conditions related to type of messaging (i.e. factual, narrative, both, control). The final model revealed that both types of messages work in generating advocacy but through two distinct influential pathways. Moreover, a message containing both facts and a narrative proved to be more effective than a message containing only a narrative or only facts.
