Enhancing public awareness for epidemic prevention is crucial for safeguarding public health. This experimental study investigated the effectiveness of a combined approach involving three persuasive elements in public health advertising. Specifically, the study examined the interplay between emotional appeals (fear messages versus efficacy messages) and spokesperson type on the public's response to health announcements. The results demonstrated that fear messages were more persuasive when conveyed by real human spokespersons (versus animated spokespersons), whereas efficacy messages were more acceptable when conveyed by animated spokespersons (versus real humans). Furthermore, the study revealed that the impact of emotional appeals and spokesperson type is moderated by benefit appeals (self-benefit or other-benefit). The joint effects of these persuasive variables on individuals' intention to adopt preventive measures indicated that the interactions significantly differed across the two types of benefit appeal. Taken together, the findings represent a pioneering contribution to the field of health communication by comparing the persuasive effects of different combinations of emotional appeals, spokesperson types, and benefit appeals on public behavior. These findings offer practical guidance for public communicators to design more appropriate health advertisements based on the results of this study, thereby enhancing public acceptance of disease prevention measures.

Tobacco pictorial warnings could employ a variety of emotional appeals to enhance effectiveness; however, little research exists to guide the selection of discrete emotional appeals. Further, it remains unclear how contextual pro-smoking norms might influence the persuasive impacts of discrete emotional appeals within pictorial warnings, especially in China, where the overall smoking rate and social acceptance remain high. To fill these gaps, this study leveraged the largest set of pictorial warnings ( = 510) tested to date. Using a randomized large-K multiple-message design, we evaluated the impacts of disgust, fear, self-anger, contempt, shame, and hope appeals among Chinese adult male smokers ( = 2,306) on perceived message effectiveness (PME). Results showed that fear, self-anger, shame, and hope appeals significantly increased PME, while disgust and contempt appeals appeared less effective. Importantly, the PME of nearly all emotional appeals - except hope appeals - was weakened for Chinese adult male smokers with higher pro-smoking normative perceptions, highlighting the importance of considering local contextual influences when implementing pictorial warnings.

Using Implementation Mapping to develop an intervention program to support veterinarians' adherence to the guideline on Streptococcus suis clinical practice in weaned pigs.
Streptococcus suis (S. suis) infections in weaned pigs are common and responsible for a high consumption of antimicrobials, and their presence is assumed to be multi-factorial. A specific evidence-based veterinary guideline to support the control of S. suis in weaned pigs was developed for veterinary practitioners in the Netherlands in 2014. Adherence to the S. suis clinical practice guideline helps veterinary practitioners to prevent and control the disease in a systematical approach and thereby improve antimicrobial stewardship and contribute to the prevention of antimicrobial resistance in animals and humans. The impact of such a clinical practice guideline on (animal) disease management depends not only on its content, but also largely on the extent to which practitioners adhere to the clinical guideline in practice. When the S. suis guideline was published, no specific activities were undertaken to support veterinarians' uptake and implementation, thereby contributing to suboptimal adherence in clinical practice. As the S. suis guideline was comprehensively written by veterinary experts following an evidence-based approach, our aim was not to judge the (scientific) quality of the guideline but to study the possibility to improve the currently low adherence of this guideline in veterinary practice. This paper describes the systematic development, using Implementation Mapping, of a theory-based intervention program to support swine veterinarians' adherence to the S. suis guideline. The knowledge, skills, beliefs about capabilities, and beliefs about consequences domains are addressed in the program, which includes seven evidence-based methods (modelling, tailoring, feedback, discussion, persuasive communication, active learning, and self-monitoring) for use in program activities such as a peer-learning meeting and an e-learning module. The intervention program has been developed for practicing swine veterinarians, lasts eight months, and is evaluated through a stepped-wedge design. The Implementation Mapping approach ensured that all relevant adopters and implementers were involved, and that outcomes, determinants (influencing factors), and objectives were systematically discussed.

Mobile mammography units (MMUs) can enhance access to breast cancer screening by providing convenient, cost-effective service, particularly for uninsured and underinsured women. However, prior studies indicate that acceptability concerns about quality and privacy, among other issues, may prevent women from utilizing MMUs. The current study employs a within-participant experimental design exposing participants to messages about different MMU characteristics to determine which characteristics are most effective in persuading them to use an MMU. The study also examined how messaging interacts with participants' ethnic identity to influence outcomes. Data were collected from a diverse sample of uninsured and underinsured women as part of a formative study to promote the utilization of a mobile mammography facility in Central Texas. Results of mixed-effect linear models show that messages about equity, appointment convenience, privacy and comfort, and quality of equipment and staff were rated as more persuasive than messages about convenience of location and language accessibility. However, Hispanic women rated language accessibility higher than other participants did. The results can guide MMU organizers and promotion managers as they determine the best approach to promote mobile mammography services in different communities.

Risk communication involves conveying potential risks to the audience. It's crucial for shaping behavior and influencing individual well-being. Previous research predominantly focused on verbal and written aspects of risk communication, with less emphasis on nonverbal cues like vocal tone. Addressing this gap, our study explores the impact of competent and warm vocal tones on risk communication across two risky decision-making paradigms, the Balloon Analogue Risk Task (BART) in Study 1 and the Gambling Task in Study 2. Results show that competent and warm vocal tones are more persuasive than neutral tones, and their effectiveness varies in different decision-making scenarios. Additionally, participants' perceived competence and warmth of vocal tones mediate this persuasiveness. This study enhances our theoretical understanding of risk communication by incorporating the impact of vocal tones. Also, it carries practical implications for marketers and practitioners, demonstrating the importance of using voice as a medium to persuade in real-world scenarios.

As video platforms such as Douyin, also known as TikTok's Chinese version, continue to grow, there is an increasing interest in the study of green advertising videos to understand their audiovisual features and their impact on audience engagement. In this research, we specifically focus on green advertising within the automotive industry. Drawing on literature from sustainability, green advertising, and communication studies, we identified seven audiovisual aspects and three persuasive strategies pertinent to green automotive advertising videos. Utilizing a mixed-methods video analysis framework, we analyzed a dataset of 2,553 green automotive advertising videos on Douyin over three years from 15 June 2020 to 15 June 2023. These videos exhibited higher loudness, a faster pace, and longer durations compared to their non-green counterparts. We categorized three distinct types of green advertising videos on Douyin and established that specific audiovisual features and persuasive strategies are significantly correlated with audience engagement levels. This study not only delineates the audiovisual characteristics of green automotive advertising in China's digital space but also contributes to the broader discourse on sustainable marketing practices on social networks like TikTok. The findings extend image-centric research to video content and provide marketers with data-driven insights for crafting effective content creation strategies on Douyin.

Youth get their sexual health information from social media, often from social media influencers (SMIs) or microcelebrities with large followings. Previous research suggests that SMIs have powerful persuasive effects on attitudes and behaviors. Thus, it is important to examine the ways in which sexual health information, such as birth control, is conveyed by SMIs. Using framing theory as a theoretical framework, this study examines characteristics of SMIs and their shared experiences pertaining to birth control. A content analysis of YouTube vlogs ( = 50) posted from December 2019-2021 was conducted on SMIs who talk about their experiences using hormonal and non-hormonal birth control. SMI status was determined based on the number of people subscribed to the YouTube channels. Results suggest that SMI YouTube videos are primarily about the discontinuation of hormonal birth control and may provide inaccurate sexual health information. Reasons for discontinuation of hormonal birth control provided by the SMIs are discussed. Future research should explore the effects of influencer sexual health messaging on beliefs, attitudes, and behaviors.

The role of the patient in hypnotherapy can be underestimated by both the therapist and the patient. This is likely due to the focus the hypnosis literature has had on the role played by the hypnotist/therapist and less on the phenomenological control (control over subjective experience) applied by the patient. Whilst early approaches to hypnosis and hypnotherapy included concepts such as autosuggestion and self-hypnosis, the role of the self has been largely overlooked. Here we aim to highlight the importance of the self in hypnotherapy and hypnosis by considering the concept of self-hypnosis and how it relates to hetero-hypnosis. We will show that: 1) historically the self was an important component of the concept of hypnosis; 2) extant theories emphasise the role of the self in hypnosis; 3) self-hypnosis is largely indistinguishable from hetero-hypnosis; 4) self-hypnosis is as effective as hetero-hypnosis. We also argue that highlighting the role of the self in hypnotherapy and hypnosis could increase feelings of self-efficacy, especially given that it can be considered a skill that can be advanced and implies self-control and not "mind-control". Highlighting the role of phenomenological control by the patient could also increase the uptake of hypnotherapy as treatment for various disorders.

This study examines the effects of message framing (loss vs. gain) and format (narrative vs. expository) on intentions to discuss flu vaccination with a close social referent. We test the effects of video messages using a two-wave web-based randomized experiment among adults in Israel (baseline: = 429, one-month follow-up: = 241). Exposure to narrative messages was positively associated with intentions to discuss flu vaccination. Exposure to loss-framed messages was positively associated with increased likelihood of discussing vaccination with the referent at follow-up. Effects of message framing and format were moderated by concern for the referent's health. Findings support the use of persuasive messages to motivate interpersonal conversation to promote vaccination. Results contribute to theory on risk-framing by showing that audiences may evaluate loss-framed messages according to their risk perceptions, when greater concern for health risks motivate action, not only for one's own health but for another person's health.

Recent advancements in large language models (LLMs) have raised the prospect of scalable, automated, and fine-grained political microtargeting on a scale previously unseen; however, the persuasive influence of microtargeting with LLMs remains unclear. Here, we build a custom web application capable of integrating self-reported demographic and political data into GPT-4 prompts in real-time, facilitating the live creation of unique messages tailored to persuade individual users on four political issues. We then deploy this application in a preregistered randomized control experiment ( = 8,587) to investigate the extent to which access to individual-level data increases the persuasive influence of GPT-4. Our approach yields two key findings. First, messages generated by GPT-4 were broadly persuasive, in some cases increasing support for an issue stance by up to 12 percentage points. Second, in aggregate, the persuasive impact of microtargeted messages was not statistically different from that of non-microtargeted messages (4.83 vs. 6.20 percentage points, respectively, = 0.226). These trends hold even when manipulating the type and number of attributes used to tailor the message. These findings suggest-contrary to widespread speculation-that the influence of current LLMs may reside not in their ability to tailor messages to individuals but rather in the persuasiveness of their generic, nontargeted messages. We release our experimental dataset, , as an empirical baseline for future research.
