Evidence-Based Health Communication in Practice: Driving Funding, Research, and Training Through the University of Texas at Austin Center for Health Communication.

Academic centers play a vital role in advancing knowledge, driving innovation, and fostering collaboration. The University of Texas at Austin Center for Health Communication was established in 2014 with the mission to improve public health through evidence-based communication research and practice. In this article, we reflect on the center history, explain our practice-oriented funding structure, and showcase examples of public health campaigns informed by theory and data, as well as professional-oriented educational programs. We also discuss the academic and community impact of our research, education, and practice and the benefits and challenges associated with this practice-led funding model. Although there are other approaches to operating academic centers, we hope the lessons we have learned can be of help to other centers dedicated to health communication research and practice.

Evaluating the persuasiveness of messages promoting mobile mammography among uninsured women.

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.

Talking About Prescription Opioid Misuse: The Effect of Family Communication Patterns and Messages Advocating Direct and Indirect Communication.

Families play an important role in addressing substance misuse and addiction. Extant literature suggests patterns of communication within families influence the ways in which they engage loved ones who may be misusing substances like prescription opioids. However, little is known regarding how strategic health messages about family communication influence individuals' intentions to engage in conversations about substance misuse. Applying a normative approach, we conducted a (2 × 2) between-participants experiment examining whether messages advocating indirect (versus direct) communication are more effective for individuals (n = 613) who describe their family as having a low (versus high) conversation orientation. Univariate analysis of variance tests show match effects for message attitudes and message elaboration. For intentions to talk with a loved one about the risks of OUD, there was only evidence of a matching effect between the message advocating indirect communication with low conversation audiences. Both message types were equally effective at influencing intentions for high conversation participants. These findings suggest message designers should consider the kinds of communication behaviors and actions advocated in appeals targeting family members. Messages that are inclusive of the conversation dynamics of particular audiences may have greater effect. In particular, for low conversation audiences, messages advocating an indirect approach may be more effective at motivating intentions to engage someone who is misusing opioids.

Psychosocial correlates of face-touching mitigation behaviors in public and private.

This study investigates psychosocial factors that influence people's face-touching mitigation behaviors. A nationwide survey was conducted online, and the results showed that perceived risk severity of touching face, and barriers and self-efficacy of not touching face were stable predictors. COVID-19 was related to a higher likelihood of mitigation behavior in public spaces. This study provides important implications to health communication and promotion for COVID-19 and general infection control.

Applying harm reduction to COVID-19 prevention: The influence of moderation messages and risk infographics.

OBJECTIVE: We propose that harm reduction messages advocating moderation versus abstinence from social interaction will be seen as less threatening and increase intentions to follow COVID-19 guidelines. We also examine two important moderators: the influence of risk framing and willingness to risk infection. METHOD: A 2 × 2 between-participants, randomized experiment (N = 476) varied infographics portraying low-risk behaviors, like going camping, versus high-risk behaviors, like attending a concert, followed by either moderation or abstinence guidelines. Participants in two additional control groups saw an infographic displaying either a full range of risk behaviors or behaviors that pose no risk, each followed by generic guidelines. RESULTS: Regression analyses show moderation messages are less freedom-threatening only when presenting low-risk behaviors. Persons more willing to risk infection found all messages more freedom-threatening; however, for these individuals, moderation messages increased behavioral intentions when risks were presented as high. CONCLUSION: This study suggests harm reduction may be applied effectively in a pandemic, where the behavior of risk-tolerant individuals, at a population level, could have suboptimal effects on curbing virus transmission. PRACTICE IMPLICATIONS: Health educators should communicate harm reduction with certain populations but also test to ensure messaging, including visuals communicating relative risks, are received as intended.

Promoting support for community water fluoridation: Testing message effects and the role of normative beliefs.

BACKGROUND: Despite evidence that community water fluoridation (CWF) protects oral health, improves health equity, is safe and cost-effective, and contributes to social well-being, little is known regarding which of these benefits should be highlighted to effectively influence support for CWF. METHODS: This within-participants study examines differences in CWF support in response to pro-CWF messages reflecting themes of oral health, health equity, CWF safety, cost-effectiveness, or social well-being among a sample of parents. Prior belief that CWF has health benefits, worry about potential health risks, and normative beliefs were also examined as independent predictors of support for each theme. RESULTS: Oral health, health equity, and safety messages significantly increased support in comparison with social well-being messages (P < .05). Oral health messages also produced greater support than cost-savings messages. Belief that CWF has health benefits positively predicted support, as did normative beliefs that one's family and physician approve of CWF. Worry about health risks and community and dentist norms were not significant predictors of support. There were no interaction effects of message themes and prior beliefs. CONCLUSIONS: Messaging focused on oral health, health equity, and the safety of CWF may be the most effective at influencing support for CWF. Preexisting personal beliefs about CWF benefits significantly predict support, but so do normative beliefs-family and physician norms in particular. PRACTICAL IMPLICATIONS: Findings suggest dental health educators should emphasize CWF's oral health benefits, such as preventing caries, over cost-saving and social well-being outcomes. They should also consider collaborating with family physicians to promote CWF and referencing other groups that may positively influence beliefs that CWF is beneficial.

Social media conversations about community water fluoridation: formative research to guide health communication.

OBJECTIVES: Community water fluoridation (CWF) is one of the greatest public health achievements of the 20th century. Despite this achievement, there are still misunderstandings about the safety of water fluoridation. Previous communication campaigns advocating CWF have been unsuccessful in combating these misunderstandings, suggesting a need for a new way to promote CWF. The goal of this article is to guide research for future campaigns by analyzing the digital conversation regarding community water fluoridation and other forms of fluoride in the state of Texas. METHODS: NUVI software extracted tweets from Twitter, and SAS Text Miner 12.1 software revealed topics related to water fluoridation. RESULTS: The results uncovered eight topics related to water fluoridation. Overall, the analysis showed mixed reactions toward water fluoridation, fluoride toothpaste, and children's dental health. CONCLUSIONS: The findings of the text analysis will guide future research, with the goal of building a pro-CWF effort in Texas.

Adolescent Attention to Disgust Visuals in Cigarette Graphic Warning Labels.

PURPOSE: Adolescents are often a target audience for disgust-eliciting antismoking messages, including graphic warning labels (GWLs) on cigarette packages. Yet, few studies have examined how adolescents attend and respond to disgust imagery frequently depicted in these messages. METHODS: A within-subjects eye-tracking experiment with middle school youth (N = 436) examined attention for GWLs that feature disgust versus nondisgust images. Hypotheses were based on emotion theory and previous findings with adult participants. This study also tested whether living with a smoker moderated effects of attention on negative emotions and risk beliefs. RESULTS: Participants paid similar levels of attention to warnings with disgust visuals as they did warnings with nondisgust visuals, accounting for other differences in the warnings. The presence of a disgust visual drew greater attention to the warning image and reduced attention for the warning text. These viewing patterns were similar for youth who live with a smoker and those who do not. Attention to disgust imagery was the only attentional factor to predict negative emotional reactions, and this relationship was driven by results observed among youth who live with a smoker. Attention to neither image nor text predicted risk beliefs. CONCLUSIONS: GWLs with disgust imagery do not trigger more or less attention to the overall warnings but do influence allocation of attention to images over text. Future work should confirm whether attention to disgust imagery itself is important for triggering negative emotional responses, particularly with youth for whom the message is more personally relevant.

Independent or synergistic? Effects of varying size and using pictorial images in tobacco health warning labels.

INTRODUCTION: Legal challenges have blocked the implementation of large, pictorial health warning labels (HWLs) in the U.S. In light of future legal questions the U.S. Food and Drug Administration may face in proposing alternative HWLs, we examined whether less restrictive HWL versions on the front of packs-smaller HWLs and/or text-only HWLs that do not include pictorial imagery-may be sufficient to promote cognitive and affective outcomes associated with smoking cessation. METHODS: We recruited low-income smokers in two separate experiments through field-based recruitment methods (Study 1, N = 497) or Amazon Mechanical Turk (MTurk) (Study 2, N = 495). In both studies, we randomly assigned participants to a no-HWL control condition or one of four HWL conditions in a 2 (pictorial vs. text-only) × 2 (50% vs. 30% size) between-subjects design. RESULTS: Relative to text-only HWLs, pictorial HWLs increased negative affect but not risk belief acceptance, cognitive elaboration about smoking harms, or quit intentions. The 50% HWLs increased quit intentions relative to the control condition in both studies. The 50% HWLs also outperformed the 30% HWLs in promoting quit intentions in Study 2. Subsequent analyses revealed that this effect in Study 2 may have been driven by the 50% HWLs strengthening the relationship between risk-related thoughts and intentions, although there was no evidence for this pattern in Study 1. We found no evidence for interaction effects between the pictorial and size manipulations. CONCLUSIONS: Our findings suggest that 50% HWLs, whether pictorial or text-only, can encourage low-income smokers to consider quitting under some conditions.

Effects of Varying Color, Imagery, and Text of Cigarette Package Warning Labels among Socioeconomically Disadvantaged Middle School Youth and Adult Smokers.

The U.S. Family Smoking Prevention and Tobacco Control Act (Tobacco Control Act) of 2009 paved the way for the Food and Drug Administration (FDA) to propose nine different graphic warning labels (GWLs) intended for prominent placement on the front and back of cigarette packs and on cigarette advertisements. Those GWLs were adjudicated as unconstitutional on the ground that they unnecessarily infringed tobacco companies' free speech without sufficiently advancing the government's public health interests. This study examines whether less extensive alternatives to the original full-color GWLs, including black-and-white GWLs and text-only options, have similar or divergent effects on visual attention, negative affect, and health risk beliefs. We used a mobile media research lab to conduct a randomized experiment with two populations residing in socioeconomically disadvantaged communities: biochemically confirmed adult smokers (N = 313) and middle school youth (N = 340). Results indicate that full-color GWLs capture attention for longer than black-and-white GWLs among both youth and adult smokers. Among adults, packages with GWLs (in either color or black-and-white) engendered more negative affect than those with text-only labels, while text-only produced greater negative affect than the packages with brand imagery only. Among youth, GWLs and text-only labels produced comparable levels of negative affect, albeit more so than brand imagery. We thus offer mixed findings related to the claim that a less extensive alternative could satisfy the government's compelling public health interest to reduce cigarette smoking rates.

Testing competing explanations for graphic warning label effects among adult smokers and non-smoking youth.

RATIONALE: The United States courts have blocked the implementation of graphic warning labels on cigarette packages (GWLs). This decision was based, in part, on the premise that GWLs are unnecessarily emotional and are meant to scare rather than inform consumers about smoking's health effects. However, research in judgment and decision-making suggests these relationships are more complex. OBJECTIVE: In this article, we draw on several theoretical frameworks that lead to competing hypotheses about the relationships between negative affect, health risk beliefs, and quit intentions (among adult smokers) or susceptibility to start smoking (among non-smoking youth). METHOD: We tested these competing mediation models using data from two experiments with two populations each-adult smokers (Ns = 313 and 238) and primarily non-smoking middle-school youth (Ns = 340 and 237). Using mobile recruitment methods, we focused specifically on individuals from socioeconomically disadvantaged communities in rural and urban areas of the Northeastern United States. RESULTS: The best fitting model across all four datasets was one in which label-induced negative affect (a) directly predicted intentions/susceptibility but also (b) indirectly predicted intentions/susceptibility via risk beliefs. Although mediation analyses did not demonstrate significant serial mediation effects of label exposure on intentions/susceptibility through negative affect then risk beliefs, there was some evidence that label exposure indirectly promoted adults' quit intentions through negative affect. Additionally, negative affect consistently mediated the indirect effect of label exposure on strengthened risk beliefs among adults and youth. CONCLUSIONS: These results speak to the importance of negative affect in directly motivating adult smokers' quit intentions but also serving an informational function, directing adult smokers and non-smoking youth to accept the health risks of smoking.

Effects of 30% and 50% Cigarette Pack Graphic Warning Labels on Visual Attention, Negative Affect, Quit Intentions, and Smoking Susceptibility among Disadvantaged Populations in the United States.

Introduction: Though the WHO Framework Convention for Tobacco Control (FCTC) calls for the implementation of large graphic warning labels (GWLs) on cigarette boxes, the courts have blocked the implementation of 50% labels in the United States. We conducted an experiment to explore whether changing the size of GWLs is associated with changes in visual attention, negative affect, risk beliefs, and behavioral intentions. Method: We recruited adult smokers (N = 238) and middle-school youth (N = 237) throughout the state of New York in May 2016. We randomly assigned participants to one of three between-subject conditions (no GWL [control], 30% GWL, 50% GWL). Results: Adult and youth participants looked at the GWLs longer when the GWL covered 50% versus 30% of the pack's front. Increasing GWL size from 30% to 50% did not influence negative affect or risk beliefs, though both GWL sizes increased negative affect relative to the no-GWL control group. Exposure to 50% GWLs increased adult smokers' intentions to quit compared to no-GWL, but smokers exposed to 30% GWLs did not differ from control. There were no differences between 50% GWLs, 30% GWLs, and control on youth smoking susceptibility. Conclusions: Findings provide some evidence of the benefits of a 50% versus 30% GWL covering the front of the pack for adult smokers and at-risk youth from socioeconomically disadvantaged backgrounds-though not on all outcomes. Implications: This research shows that 30% GWLs on cigarette packages increase negative affect relative to packages without front-of-package GWLs. Larger GWLs on cigarette packages (50% vs. 30%) increase visual attention to the warning and its pictorial content among low-SES smokers and at-risk youth but do not further increase negative affect. A 50% GWL increased adults' quit intention compared to no GWL at all, but we were underpowered to detect modest differences in quit intentions between a 50% and 30% GWL. Future work should thus continue to explore the boundary conditions under which relatively larger GWLs influence cognitive, affective, and behavioral outcomes.
