Contributions to Research and Practice Made by the National Cancer Institute's Health Communication and Informatics Research Branch.

The Health Communication and Informatics Research Branch at the U.S. National Cancer Institute was founded in 1999 in response to increasing evidence demonstrating a link between effective health communication and improved cancer-related outcomes and in recognition of the rapid and dramatic technological changes that were transforming health communication at the turn of the 21st century. For the past 25 years, the Health Communication and Informatics Research Branch has been conducting and supporting research at the forefront of emerging cancer communication trends and technologies, making numerous contributions to health communication science, public health, and cancer control practice. In this essay, we provide a brief history of the branch and the context that led to its establishment, discuss contributions made by the branch to health communication research and practice through key projects and initiatives, and conclude by highlighting health communication and informatics research priorities that offer opportunities for significant impact going forward in light of the challenges posed by the current communication environment.

Increasing Receptivity to COVID-19 Public Health Messages with Self-Affirmation and Self vs. Other Framing.

There remains an urgent need for effective communication about the importance of widespread adherence to behavioral recommendations to control the COVID-19 pandemic that will also reduce resistance to such guidance. We examined two strategies for COVID-19 communication- (1) self-affirmation (reflecting on a personal value in order to boost self-integrity and reduce defensiveness to potentially threatening information); and (2) manipulating self/other message framing - and moderation of these strategies by COVID-19 risk. 600 participants (Mage = 32.55, 51% female) were recruited for an online study and, after assessment of risk factors for severe COVID-19 infection, were exposed to the experimental manipulations. Three classes of defensive responses were considered as outcomes of interest: reactance, attitudinal responses, and behavioral responses. We found that participants derogated the self-focused message more than the other-focused message. Further, other-focused messaging and/or self-affirmation were more likely to elicit positive responses among individuals at higher risk for COVID-19 complications. Our findings suggest having individuals affirm values prior to viewing COVID-19 messages, and framing messages in terms of the importance of protecting others, may be beneficial strategies for encouraging responsiveness - particularly if the targets of such messages are at risk of COVID-19 complications themselves.

Future-oriented Emotions and Decisions to Receive Genomic Testing Results Among U.S. Adults of African Ancestry.

BACKGROUND: Future-oriented emotions are associated with consequential health decision-making, including genomic testing decisions. However, little is known about the relative role of various future-oriented emotions in such decisions. Moreover, most research on predictors of decision making regarding genomic testing is conducted with white participants. PURPOSE: This study examined the role of future-oriented emotions in decisions to receive genomic testing results in U.S. individuals of African descent. METHODS: We analyzed cross-sectional survey data from a genomic sequencing cohort (N = 408). All participants identified as African, African-American, or Afro-Caribbean (Mage = 56.3, 74.7% female). Participants completed measures assessing anticipatory affect (worry about genetic testing results), anticipated distress (feeling devastated if genetic testing showed an increased risk for fatal disease), and anticipated regret (regretting a decision not to learn results). Outcomes were intentions for learning actionable, nonactionable, and carrier results. RESULTS: Anticipated regret was robustly positively associated with intentions to receive actionable (b = 0.28, p < .001), nonactionable (b = 0.39, p < .001), and carrier (b = 0.30, p < .001) results. Anticipated distress was negatively associated with intentions to receive nonactionable results only (b = -0.16, p < .01). Anticipatory negative affect (worry) was not associated with intentions. At higher levels of anticipated regret, anticipated distress was less strongly associated with intentions to receive nonactionable results (b = 0.14, p = .02). CONCLUSIONS: Our results highlight the role of future-oriented emotions in genomic testing among participants who are typically underrepresented in genomic testing studies and behavioral medicine broadly. Future work should examine whether interventions targeting future-oriented emotions such as anticipated regret may have clinically meaningful effects in genetic counseling in similar cohorts.

Future-oriented emotions (emotions directed toward a future outcome, such as worrying about a future outcome, or expecting to feel distress or regret if a particular outcome occurs) are important predictors of health decisions, including decisions to seek and receive genomic testing results. Understanding how such factors relate to decisions to receive genetic testing results is particularly important in medically-underserved groups such as individuals of African ancestry, who are underrepresented in genomics and behavioral science research. We analyzed survey responses from a genomic sequencing cohort where all 408 participants identified as African, African-American, or Afro-Caribbean, and were asked about their level of worry, anticipated distress, and anticipated regret about results, plus their interest in receiving three types of genomic testing results from the study. We found that participants who expected that they would regret their decision to not learn the results had stronger intentions to receive all three types of results; those who expected to feel distressed by a genetic testing result that showed an increased risk for a fatal disease were less interested in nonactionable genetic testing results specifically. Our results highlight the differing roles of specific types of future-oriented emotions in genomic testing decisions, among participants who are typically underrepresented in this type of research.

Understanding responses to different types of conflicting information about cancer prevention.

BACKGROUND: Individuals are regularly exposed to conflicting information about health; however, understanding of how individuals respond to different types of conflicting information is limited. METHODS: In total, 1027 US adults were randomly assigned to 1 of 8 conflicting information messages about nutrition and cancer risk, depicting 1/4 conflicting information types (conflict in evidence - sources A and B agree the evidence is mixed; conflict between two expert sources - sources A and B present conflicting evidence about nutrition and cancer risk; conflict within the same expert source - source A changes its own recommendation about the evidence; no conflict control) crossed by 1/2 baseline recommendations with which new information conflicted (limit vs. do not limit red meat intake to reduce cancer risk). RESULTS: Compared to the control, each conflicting information type led to lower perceived scientific consensus about how much red meat one should eat (p < .001); conflict in evidence (p = .004) and between sources (p = .006) led to lower trust in scientists. Intentions to consume red meat more frequently were higher in the conflicting information conditions than control in the group initially told to "limit red meat" and lower in the "do not limit red meat" group (p = .022). Conflict within the same source led to higher perceived scientific consensus compared to conflict in evidence (p = .007) and between sources (p = .013); it also lowered intentions to consume red meat more frequently compared to conflict in evidence, but only in the "do not limit red meat" condition (p = .033). Conflict in evidence (p = .007) and within the same source (p = .013) increased cancer fatalism compared to conflict between sources. CONCLUSIONS: Conflict in scientific evidence and conflict arising from the same expert source (e.g., a changing public health guideline) may have pernicious effects. Future efforts could investigate how best to publicly communicate these instances of scientific conflict to minimize negative impact.

Factors Associated With COVID-19 Behavioral Intentions: Findings From an Online Survey.

PURPOSE: The COVID-19 pandemic provides a novel context through which to evaluate salient factors for promoting behavioral change. We examined how attitudes, perceived community behaviors, and prior related behaviors predict intentions to (1) receive COVID-19 vaccination and (2) practice social distancing. DESIGN: Cross-sectional online survey administered through Amazon's Mechanical Turk in September 2020. SUBJECTS: A convenience sample of US adults (N = 1804). MEASURES: COVID-19 vaccination and social distancing intentions were measured on a 7-point Likert scale. Predictor variables included general vaccination and social distancing attitudes, perceived community mask-wearing, prior influenza vaccination, prior social distancing, and socio-demographics. ANALYSIS: Descriptive statistics and linear regressions. RESULTS: Thirty percent of respondents reported a strong willingness to receive COVID-19 vaccination, while 67% strongly intended to engage in social distancing. In regression analyses, vaccination intention was predicted by positive vaccine attitudes (b = .84; 95%CI: .78, .90; P < .001), prior influenza vaccination (b = -.47; 95%CI: -.63, -.32; P < .001), and perceived community mask-wearing (b = -.28; 95%CI: -.56, -.01; P=.049). Intention to practice social distancing was predicted by positive attitudes (b = .65; 95%CI: .61, .69; P < .001), prior social distancing (b = -.49; 95%CI: -.59, -.39; P < .001), and perceived community mask-wearing (b = -.28; 95%CI: -.46, -.09; P = .003). CONCLUSION: Findings have implications for health promotion efforts. Messages that are targeted and tailored on pre-existing attitudes may be more effective. Additionally, leveraging prior behaviors and perceived community behavior may improve communication strategies.

Effects of Narrative Messages on Key COVID-19 Protective Responses: Findings From a Randomized Online Experiment.

PURPOSE: We investigated the effectiveness of narrative vs non-narrative messages in changing COVID-19-related perceptions and intentions. DESIGN/SETTING: The study employed a between-subjects two-group (narratives vs non-narratives) experimental design and was administered online. SUBJECTS/INTERVENTION: 1804 U.S. adults recruited via Amazon MTurk in September 2020 were randomly assigned to one of two experimental conditions and read either three narrative or three non-narrative messages about social distancing, vaccination, and unproven treatments. MEASURES: Perceptions and intentions were assessed before and after message exposure (7-point scales). ANALYSIS: Using multivariable regression, we assessed main effects of the experimental condition (controlling for baseline measures) and interactions between the condition and pre-exposure perceptions/intentions in predicting post-exposure outcomes. RESULTS: Compared to non-narratives, narratives led to (1) less positive perceptions about the benefits of unproven treatments (Mnarrative = 3.60, Mnon-narrative = 3.77, P = .007); and (2) less willingness to receive an unproven drug (Mnarrative = 3.46, Mnon-narrative = 3.77, P < .001); this effect was stronger among individuals with higher baseline willingness to receive unproven drugs (baseline willingness = 2.09: b = -.06, P = .461; baseline willingness = 3.90: b = -.30, P < .001; baseline willingness = 5.71: b = -.55, P < .001). Narratives also led to more positive perceptions of vaccine safety/effectiveness, but only among individuals with lower baseline vaccine perceptions (baseline perceptions = 4.51: b = .10, P = .008; baseline perceptions = 5.89: b = .04, P = .167; baseline perceptions = 7: b = -.01, P = .688). CONCLUSION: Narratives are a promising communication strategy, particularly for topics where views are not entrenched and among individuals who are more resistant to recommendations.

Self-affirmation inductions to reduce defensive processing of threatening health risk information.

OBJECTIVE: Self-affirmation reduces defensiveness toward threatening health messages. In this study, we compared several possible self-affirmation inductions in order to identify the most effective strategy. DESIGN: Women at increased risk for breast cancer (i.e. who drink 7+ drinks per week) were recruited through Amazon Mechanical Turk (N = 1,056), randomly assigned to one of 11 self-affirmation conditions, and presented with an article about the link between alcohol intake and breast cancer risk. MAIN OUTCOME MEASURES: Participants answered questions that measured key indices of message acceptance (risk perception, message endorsement), future alcohol consumption intentions, and action plans to reduce alcohol intake. RESULTS: Participants who affirmed health vs. non-health values did not differ in behavioral intentions or action plans to reduce alcohol intake. General values vs. health essay affirmations led to higher odds of reporting some vs. no action plans to reduce alcohol consumption. Essay- vs. questionnaire-based inductions led to higher breast cancer worry and intentions to reduce alcohol consumption. CONCLUSION: Overall, self-affirmation inductions that include an explicit focus on values (general or health-related) and self-generation of affirming thoughts through essay writing, are most potent in changing behavioral intentions and action plans to change future health behavior.

Associations between absolute and relative electronic cigarette harm perceptions and information-seeking behaviours among US adult current, former and never smokers.

INTRODUCTION: Electronic cigarette (e-cigarette) harm perceptions and information seeking behaviours are both important antecedents of e-cigarette use, yet the relationship between them has been rarely studied. We assessed how absolute (e-cigarettes are harmful to my health) and relative harm perceptions (e-cigarettes are more/less harmful than cigarettes) were associated with specific e-cigarette information seeking behaviours in a sample of current, former and never cigarette smokers. METHODS: We used data from US adults in two cycles of the Health Information National Trends Survey (HINTS-FDA 2015, n = 3738; 2017, n = 1736). Analyses controlled for socio-demographics, ever e-cigarette use and survey cycle. Data were analysed between January and August 2020. RESULTS: Higher relative harm perceptions were associated with lower odds of having sought any information on e-cigarettes [adjusted odds ratio 0.61, 95% confidence interval (0.48, 0.84)] and on how to use e-cigarettes to quit smoking specifically [adjusted odds ratio 0.59, 95% confidence interval (0.38, 0.91)]. Smoking status did not moderate associations between absolute or relative harm perceptions and information seeking behaviours, nor was it associated with specific information seeking behaviours after adjusting for covariates. DISCUSSION AND CONCLUSIONS: The risks of e-cigarettes relative to combusted cigarettes (as opposed to the absolute risks of e-cigarettes) appear to be more important in individuals' information seeking behaviours about e-cigarettes. Public health messages could ensure that all individuals understand how one's health risk would change if they exclusively used e-cigarettes, switched to e-cigarettes completely or used both products.

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.e., message content) and how to say it (i.e., message executions), and how these decisions impact message persuasiveness. Following a synthesis of each major line of literature, we discuss how science-based principles of message design can be used in COVID-19 public health messaging. Additionally, we identify emerging challenges for public health messaging during the COVID-19 pandemic and discuss possible remedies. We conclude that communication science offers promising public health messaging strategies for combatting COVID-19 and future pandemics.

The role of future-oriented affect in engagement with genomic testing results.

Future-oriented emotions such as anticipatory affect (i.e., current affect experienced regarding a potential future outcome) and anticipated affect (i.e., expectations about potential future affect), are uniquely associated with health decision-making (e.g., electing to receive results of genomic testing). This study investigated the degree to which negative anticipated and anticipatory emotions predict health decision making over time, and whether such emotions predict social, emotional, and behavioral responses to anticipated information (e.g., genomic testing results). 461 participants (M age = 63.9, SD = 5.61, 46% female) in a genomic sequencing cohort who elected to receive genomic sequencing (carrier) results were included in the current study. Anticipated and anticipatory affect about sequencing results were assessed at baseline. Psychological and behavioral responses to sequencing results, including participants' reported anxiety, decisional conflict, and distress about sequencing results, whether they shared results with family members, and their intentions to continue learning results in the future, were collected immediately, one month, and/or six months after receiving results. More negative anticipated and anticipatory affect at baseline was significantly and independently associated with lower intentions to continue learning results in the future, as well as higher levels of anxiety and uncertainty at multiple time points after receiving results. Anticipated negative affect was also associated with greater decisional conflict, and anticipatory negative affect was also associated with greater distress after receiving results. Future-oriented emotions may play an important role in decisions that unfold over time, with implications for genomic testing, behavioral medicine, and health decision-making broadly.

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 (N = 151). Participants held negative explicit and implicit attitudes toward smoking. We found no direct effect of self-affirmation on either implicit or explicit attitudes. Self-affirmation and risk level did not interact to predict either attitude type. We discuss findings in terms of self-affirmation theory, attitude measurement, and the meta-cognitive model of attitude change.

The Unintended Consequences of Rape Disclosure: The Effects of Disclosure Content, Listener Gender, and Year in College on Listener's Reactions.

Rape is prevalent on American college campuses. Rape survivors often disclose their experience to their peers in hope of receiving support and obtaining justice (i.e., the intended consequences of disclosure). Yet, rape disclosures may also lead to unintended consequences, such as stigma. How peers react to survivors' disclosures of rape greatly influences survivors' recovery and their decision to press charges against their perpetrators. In this article, we explore gender differences in responses to rape disclosures. Using an experimental design (N = 391), we investigate reactions to stigmatizing (versus nonstigmatizing) rape disclosures. We find that, when controlling for the experimental condition, college men stigmatize the rape survivor more than college women. However, in response to a stigmatizing (versus nonstigmatizing) rape disclosure, college women who have been in college longer, compared with college men, have more stigmatizing reactions toward the person disclosing that information. Their reactions then predict increased social distance between the recipient of the disclosure and rape survivors.

"Tobacco and Water": Testing the Health Halo Effect of Natural American Spirit Cigarette Ads and Its Relationship with Perceived Absolute Harm and Use Intentions.

In 2015, the FDA formally warned Santa Fe Natural Tobacco Company that their "natural" and "additive-free" claims for its Natural American Spirit cigarettes conveyed reduced harm to consumers. In a settlement, Santa Fe was allowed to continue using the word "natural" in the brand name and the phrase "tobacco and water". The company also uses eco-friendly language and plant imagery and these tactics have also been shown to communicate reduced product harm. In this study, we propose the health halo effect as an overarching framework for explaining how these ad tactics mislead consumers in an effort to provide more comprehensive guidance for regulatory action. In a between-subjects experiment, 1,577 US young adults, ages 18-24, were randomly assigned to view one of five Natural American Spirit cigarette ads featuring either: 1) eco-friendly language; 2) plant imagery; 3) the phrase "tobacco and water"; 4) all of these tactics; or 5) a control condition featuring none of these tactics. In line with past research, ads with the phrase "tobacco and water" or with all the tactics together (vs. control) created a health halo effect, increasing perceptions that Natural American Spirit cigarettes were healthier and had less potential to cause disease; these tactics also had an indirect positive effect on smoking intentions through reduced perceptions of the brand's potential to cause disease and perceived absolute harm. Inconsistent with prior work, the eco-friendly language and plant imagery (vs. control) reduced healthfulness perceptions, increased perceptions of absolute harm, and had an indirect negative effect on smoking intentions. We contribute to past research showing that Natural American Spirit cigarette ad tactics mislead consumers. Inconsistent findings are explained in terms of stimuli design and processing of message features, indices of relative message persuasiveness, and multiple versus single-message designs.

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). In an online experiment, participants (N = 3,049) were presented with mock packages of snack foods and given the opportunity to view the NFL. Results showed that products including "vita" in their name were perceived as more healthful than those that did not include "vita" in their name, even though their nutritional content was the same. Additionally, vita snack foods (compared to regular snack foods) were rated as significantly higher in nutrients to promote, such as fiber, vitamin D, calcium, vitamin C, and potassium and lower in nutrients to limit, such as calories, sugar, and saturated fat. Viewing the NFL appeared to mitigate the effects of product naming.

Nutrient Content Claims: How They Impact Perceived Healthfulness of Fortified Snack Foods and the Moderating Effects of Nutrition Facts Labels.

Nutrient content claims (NCCs) may inflate perceived healthfulness of nutritionally poor foods. The aim of this study is to experimentally test the effects of NCCs on consumers' perceptions of fortified snack foods in terms of the presence of both healthful and less healthful nutrients, as well as their intentions to consume such products. It also explores the potential moderating effects of reading Nutrition Facts Labels (NFL) on the influence of NCCs. Data for this study were collected through a web-based experiment (N = 5,076). Results indicated that the presence of an NCC on a fortified snack food product increased perceived healthfulness of that product, perceptions of the presence of healthful nutrients, and intentions to consume the product. The presence of NCCs also decreased perceptions of the presence of certain less healthful nutrients. Reading the NFL had mixed effects on the impact of NCCs.

Understanding the Adoption Process of National Security Technology: An Integration of Diffusion of Innovations and Volitional Behavior Theories.

After the 9/11 terrorist attacks, the U.S. government initiated several national security technology adoption programs. The American public, however, has been skeptical about these initiatives and adoption of national security technologies has been mandated, rather than voluntary. We propose and test a voluntary behavioral intention formation model for the adoption of one type of new security technology: portable radiation detectors. Portable radiation detectors are an efficient way of detecting radiological and nuclear threats and could potentially prevent loss of life and damage to individuals' health. However, their functioning requires that a critical mass of individuals use them on a daily basis. We combine the explanatory advantages of diffusion of innovation with the predictive power of two volitional behavior frameworks: the theory of reasoned action and the health belief model. A large sample survey (N = 1,482) investigated the influence of factors identified in previous diffusion of innovation research on portable radiation detector adoption intention. Results indicated that nonfinancial incentives, as opposed to financial incentives, should be emphasized in persuasive communications aimed at fostering adoption. The research provides a new integration of diffusion of innovation elements with determinants of volitional behavior from persuasion literature, and offers recommendations on effective communication about new security technologies to motivate public adoption and enhance national safety.

Stigmatizing the other: An exploratory study of unintended consequences of eating disorder public service announcements.

This research explores the intended and unintended consequences of eating disorder public service announcements. We assessed participants' attitudes toward eating disorders and people with eating disorders, willingness to interact with people with eating disorders, and experience with eating disorders (covariate) at Time 1. At Time 2, participants were randomly assigned to watch a stigmatizing or a non-stigmatizing eating disorder public service announcement. Exposure to the stigmatizing public service announcement resulted in more negative attitudes toward eating disorders and in less willingness to interact with people with eating disorders, but not in significantly more negative attitudes toward people with eating disorders. The discussion highlights the practical implications for health communication campaigns.
