Vivifying Outbreaks: Investigating the Influence of a Forecast Visual on Risk Perceptions, Time-Urgency, and Behavioral Intentions

ABSTRACT Although visual depictions of epidemiological data are not new in public health, the US public saw more of them during the COVID-19 pandemic than ever before. In this study, we considered visualizations of forecasts (i.e. predictions of how a disaster will unfold over time) formatted as line charts. We investigated how two choices scientists make when creating a forecast visual – the outcome of focus (cases or deaths) and the amount of data provided (more or less data) about the past or the potential future – shape behavioral intentions via risk-related appraisals (e.g. threat and efficacy). In an online experiment, participants (N = 236) viewed a written health alert about a novel airborne virus, with one of the eight versions of a forecast visual or no visual (text only). The results of the experiment showed that exposing people to a health alert with a forecast visual in it may be less effective than anticipated. Reading a written health alert with a forecast visual was, at best, equal to outcomes from reading an alert without it, and sometimes it performed worse: participants appraised the novel virus as a less urgent threat and the recommended solutions as less efficacious. Implications of the findings for theories of risk and visual health communication and practical considerations for future health communicators were discussed.

Emoji and visual complexity in health information design: A moderated serial mediation model

Social media is a valuable tool that enables public health organizations to communicate effectively. To enhance the reach of health communication on social media, scholars have proposed that emoji be used to convey scientific information. The current study explored the influence of emoji on the effectiveness of health communication on social media. Automated content analysis revealed that the presence of emoji in online health information resulted in higher levels of social media engagement (SME) than the absence of emoji did. Additionally, a 2 (emoji: present versus absent) × 3 (visual complexity of information design: low versus medium versus high) online experiments revealed that the presence of emoji in health information sequentially increased perceived enjoyment and perceived interactivity, thereby promoting SME. However, this effect is influenced by the visual complexity of health information designs. The presence of emoji is only effective in increasing SME with health information presented using a design with low or medium visual complexity. This study provides theoretical and practical insights into visual health communication and health information design.

Advancing Visual Health Communication Research to Improve Infodemic Response

ABSTRACT During public health crises like the ongoing novel coronavirus pandemic, there is a need to amplify and improve critical health communication messages. This need is due to pandemics producing infodemic conditions, meaning the public information environment is oversaturated with information of questionable accuracy and utility. The strategic use of visuals can be leveraged to improve the quality of health communication during public health crises and lessen the unintended effects of infodemic conditions. In this essay, we review previous visual communication theorizing and research that provide insights for effective and efficient use of graphical (e.g., data visualizations) and illustrative (e.g., photos, illustrations, and content features) visuals. We also discuss and advocate for more systematic research on visual misinformation and visual narratives, as there are significant gaps in the literature about how people interpret, act on, and engage with these visual content types. More systematic research about these areas of visual health communication research will improve public communication during future public health crises.

Saving Lives through visual health communication: A multidisciplinary team approach

Introduction: Saving Lives is a public health awareness charity that aims to educate the UK public about HIV and encourage testing for the virus.In May 2011 Saving Lives contacted the Medical Illustration department at Heart of England NHS Foundation Trust to discuss the idea of working together to develop a national HIV awareness campaign.Methods: A number of local sporting celebrities were invited to a studio photography session. All the sports stars and celebrities were photographed on a Mamiya 645 AFDII camera, with PhaseOne P30 + digital back, using prime 35mm, 55mm and 80mm lenses. During the photography sessions, the team's film maker captured video footage of the subjects being photographed. Once the final avengers’ graphical composition had been created, it was applied to the posters, billboards and public transport signs for the campaign.Results: In the three-month period following the campaign launch, survey research was carried out, the initial data being recorded by a questionnaire which was provided to each of the 1800 patients attending the Heartlands Hospital sexual health clinic for HIV testing.Conclusion: Following the launch of the initial campaign, the Saving Lives team continues to produce material to assist in the promotion of the charity and its message. Its success has led to it becoming an on-going long-term project, and to date the team have photographed and filmed 33 sporting stars and visited numerous sporting institutes.

A Systematic Review of Visual Image Theory, Assessment, and Use in Skin Cancer and Tanning Research

Visual images increase attention, comprehension, and recall of health information and influence health behaviors. Health communication campaigns on skin cancer and tanning often use visual images, but little is known about how such images are selected or evaluated. A systematic review of peer-reviewed, published literature on skin cancer and tanning was conducted to determine (a) what visual communication theories were used, (b) how visual images were evaluated, and (c) how visual images were used in the research studies. Seven databases were searched (PubMed/MEDLINE, EMBASE, PsycINFO, Sociological s, Social Sciences Full Text, ERIC, and ABI/INFORM) resulting in 5,330 citations. Of those, 47 met the inclusion criteria. Only one study specifically identified a visual communication theory guiding the research. No standard instruments for assessing visual images were reported. Most studies lacked, to varying degrees, comprehensive image description, image pretesting, full reporting of image source details, adequate explanation of image selection or development, and example images. The results highlight the need for greater theoretical and methodological attention to visual images in health communication research in the future. To this end, the authors propose a working definition of visual health communication.

Mapping as a Visual Health Communication Tool: Promises and Dilemmas

In the era of evidence-based public health promotion and planning, the use of maps as a form of evidence to communicate about the multiple determinants of cancer is on the rise. Geographic information systems and mapping technologies make future proliferation of this strategy likely. Yet disease maps as a communication form remain largely unexamined. This content analysis considers the presence of multivariate information, credibility cues, and the communication function of publicly accessible maps for cancer control activities. Thirty-six state comprehensive cancer control plans were publicly available in July 2005 and were reviewed for the presence of maps. Fourteen of the 36 state cancer plans (39%) contained map images (N = 59 static maps). A continuum of map interactivity was observed, with 10 states having interactive mapping tools available to query and map cancer information. Four states had both cancer plans with map images and interactive mapping tools available to the public on their Web sites. Of the 14 state cancer plans that depicted map images, two displayed multivariate data in a single map. Nine of the 10 states with interactive mapping capability offered the option to display multivariate health risk messages. The most frequent content category mapped was cancer incidence and mortality, with stage at diagnosis infrequently available. The most frequent communication function served by the maps reviewed was redundancy, as maps repeated information contained in textual forms. The social and ethical implications for communicating about cancer through the use of visual geographic representations are discussed.
