RESUMO

BACKGROUND: In May 2020, news outlets reported misinformation about the Centers for Disease Control (CDC) related to COVID-19. Correcting misinformation about outbreaks and politics is particularly challenging. Affective belief echoes continue to influence audiences even after successful correction. Narrative and emotional flow scholarship suggest that a narrative corrective with a positive ending could reduce belief echoes. Therefore, this study investigated the efficacy of a narrative corrective with a relief ending for correcting misinformation about the CDC. METHODS: Between 29 May and 4 June 2020, we tested the effectiveness of a narrative to correct this misinformation. Participants in the United States (N = 469) were enrolled via Qualtrics panels in an online message experiment and randomized to receive a narrative corrective, a didactic corrective or no corrective. RESULTS: The narrative corrective resulted in lower endorsement of the misinformation compared with the control and the didactic corrective. The narrative corrective had a positive indirect effect on perceived CDC competence and mask wearing intentions for politically moderate and conservative participants via relief. CONCLUSIONS: Public health institutions, such as the CDC, should consider utilizing narrative messaging with positive emotion endings to correct misinformation. Narratives better address affective belief echoes, particularly for counter-attitudinal audiences.

RESUMO

The theory of normative social behavior (TNSB) postulates that people are influenced by others' behaviors, which they observe from messages and experience. In addition to focusing on perceived (i.e., descriptive and injunctive) norms, the TNSB was expanded to include collective norms, which represent what people actually do. Testing this expanded theoretical model, the current study examined whether two types of collective norms - collective political norms and collective regional norms - interacted with descriptive norms to influence pandemic mask wearing behavior expectations among U.S. adults (N = 444). The interaction was statistically significant for collective political norms (ß = -.74, p = .009) but not collective regional norms (ß = -.16, p = .85). Specifically, descriptive norms were related to increased mask wearing expectation for all values of political party collective norms, but the effects were stronger when political party collective norms were low (i.e., low mask wearing behavior was normative). The findings support the inclusion of collective norms in the TNSB, clarify the relationships among different types of norms, and provide insights for norms-based interventions.

RESUMO

During the COVID-19 pandemic, journalists were encouraged to convey uncertainty surrounding preliminary scientific evidence, including mentioning when research is unpublished or unverified by peer review. To understand how public audiences interpret this information, we conducted a mixed method study with U.S. adults. Participants read a news article about preprint COVID-19 vaccine research in early April 2021, just as the vaccine was becoming widely available to the U.S. public. We modified the article to test two ways of conveying uncertainty (hedging of scientific claims and mention of preprint status) in a 2 × 2 between-participants factorial design. To complement this, we collected open-ended data to assess participants' understanding of the concept of a scientific preprint. In all, participants who read hedged (vs. unhedged) versions of the article reported less favorable vaccine attitudes and intentions and found the scientists and news reporting less trustworthy. These effects were moderated by participants' epistemic beliefs and their preference for information about scientific uncertainty. However, there was no impact of describing the study as a preprint, and participants' qualitative responses indicated a limited understanding of the concept. We discuss implications of these findings for communicating initial scientific evidence to the public and we outline important next steps for research and theory-building.

RESUMO

The World Health Organization (WHO) officially declared COVID-19 a pandemic on March 11, 2020. It was a time of significant uncertainty as experts were not yet certain whether social distancing behaviors were necessary to slow the spread of the virus. Some public communicators opted to acknowledge uncertainty based on the limited evidence, whereas others downplayed uncertainty. This situation provided researchers with an opportunity to advance theory by explicating and testing cognitive responses to message uncertainty. Immediately following the WHO declaration (March 13-19, 2020), U.S. adults (N = 1186) were randomly assigned to one of six conditions in a 2 (message uncertainty: low, high) × 3 (argument support: expert, threat, precedent) between-participants experiment. Overall, perceived uncertainty negatively mediated the impact of message uncertainty on intentions. However, participant education was a key moderator. For those with more than a high school education, uncertain messages were related to higher intentions to social distance through increased critical reflection. For those with a high school education or less, uncertain messages were related to lower intentions through decreased message credibility.

RESUMO

OBJECTIVE: One way to communicate skin cancer risk is through ultraviolet (UV) photographs, which can depict the target person (tailored visual) or someone else (stock visual). There is a need for more longitudinal research examining the relative impact of tailored UV photographs compared with other message interventions that could increase sun safe behaviors. METHOD: Students 14-18 years of age (N = 654) at eleven high schools in Utah were recruited to participate in a longitudinal experiment (assessments: pretest, posttest, 1 month follow-up) comparing the relative persuasive impact of receiving either (a) stock and tailored UV photographs or (b) stock UV photographs and an implementation intervention on outdoor tanning behavior. Participants completed measures of fear, appearance norms and benefits, threat susceptibility/severity, self-efficacy, response efficacy, freedom threat, reactance, and outdoor tanning behavior. RESULTS: Compared with the implementation intervention, participants in the tailored UV condition reported increased fear and freedom threat and decreased appearance norms and benefits of tanning immediately following exposure to the intervention and decreased outdoor tanning 1 month after the intervention. Indirect effects also emerged with tailored UV exposure decreasing outdoor tanning via appearance benefits and increasing outdoor tanning when immediate fear triggered psychological reactance. CONCLUSIONS: The results contribute to research on lay reactions to tailored visuals, implementation interventions, and theorizing the indirect effects of affect and cognition across time.

RESUMO

Understanding how to portray uncertain science to the public is a pressing goal for science communication. This study compared US public audience reactions to a news article depicting a novel discovery in neurogenomics as certain or uncertain, with statements of (un)certainty attributed to either affiliated or unaffiliated scientists. The uncertainty disclosure had no main effect on perceived news article credibility, scientist trustworthiness, objectivity of the scientists' depiction, or willingness to participate in genomic research. However, news credibility and scientist objectivity ratings were higher for uncertainty disclosure attributed to the affiliated scientists. Participants with greater preference for information about uncertainty found the scientists more trustworthy, their depictions more balanced, and the news article more credible when the research was described as uncertain, and these effects were stronger for affiliated scientist attribution. Findings underscore the important roles of disclosure source and audience characteristics in public reactions to media representations of scientific uncertainty.

RESUMO

Psychological reactance theory posits individuals seek to restore freedom when threatened. Communication scholars have hypothesized persuasive messages can constitute threats to freedom. The current study engages questions about the potential for different forms of narratives in public service announcements (PSAs) to trigger freedom threats by examining responses to a PSA campaign that utilized three forms of narrative (celebrity testimonials, peer testimonials, and accident stories) to decrease adolescent texting and driving intentions. Participants (N = 214) watched anti-texting and driving narratives, and completed measures of threat to freedom, anger, negative cognition, and attitudes/intentions toward texting/driving. Compared to celebrity/peer testimonial PSAs, accident stories triggered increased anger and, indirectly, decreased intentions to drive safely. The results also suggest the need for continued examination of the best way to model psychological reactance theory, and the value of further research explicating anger as a mechanism of message effects.

RESUMO

BACKGROUND: Precision medicine research depends upon recruiting large and diverse participant cohorts to provide genetic, environmental, and lifestyle data. How prospective participants react to information about this research, including depictions of uncertainty, is not well understood. PURPOSE: The current study examined public responses to precision medicine research, focusing on reactions toward (a) uncertainty about the scientific impact of sharing data for research, and (b) uncertainty about the privacy, security, or intended uses of participant data. METHODS: U.S. adults (N = 674; 51.9% male; 50% non-Hispanic white; Mage = 42.23) participated in an online experimental survey. Participants read a manipulated news article about precision medicine research that conveyed either certainty or uncertainty of each type (scientific, data). Participants then rated their attitudes toward the research, trust in the researchers, and willingness to join a cohort. We tested direct and mediated paths between message condition and outcomes and examined individual characteristics as moderators. RESULTS: Overall attitudes were positive and a majority of participants (65%) reported being somewhat or very likely to participate in precision medicine research if invited. Conveying uncertainty of either type had no overall main effect on outcomes. Instead, those who reported perceiving greater uncertainty had lower attitudes, trust, and willingness to join, while those with more tolerance for uncertainty, support for science, and scientific understanding responded favorably to the scientific uncertainty disclosure. CONCLUSIONS: Findings suggest responses to precision medicine research uncertainty are nuanced and that successful cohort enrollment may be well-supported by a transparent approach to communicating with prospective participants.

RESUMO

BACKGROUND: Effective communication of cancer-related genetic and genomic testing (CGT) with patients and the public is paramount to transforming and managing cancer prevention, detection, and care. Behavioral and social science theories could improve communication effectiveness and, in turn, health outcomes. METHODS: In this study, we characterized the use of theory in recent research on communication about CGT from 2010 to 2017. RESULTS: Of 513 empirical papers focusing on communication about CGT, only 119 (23%) utilized any theory in the study design. Behavior change and health psychology/cognitive representation theories (24.2% and 21.9%, respectively) were the most commonly used with minimal use of communication theories (3%). Theories were primarily used to guide hypotheses or research question development (73.9%), and for selecting measures or codes (68.9%). Approximately half of the papers (48.3%) related their study findings to the referenced theory. Fewer papers (14.3%) discussed implications of the findings for the theory. CONCLUSIONS: While theories are being utilized to inform study design, few discuss their results in the context of theoretical implications and thus decrease potential generalizability. Greater use of theory could help scholars to identify and develop theories suited to this clinical context and inform our understanding of related communication processes more broadly.

RESUMO

Objectives. To examine prevalence and predictors of digital health engagement among the US population. Methods. We analyzed nationally representative cross-sectional data on 7 digital health engagement behaviors, as well as demographic and socioeconomic predictors, from the Health Information National Trends Survey (HINTS 5, cycle 2, collected in 2018; n = 2698-3504). We fitted multivariable logistic regression models using weighted survey responses to generate population estimates. Results. Digitally seeking health information (70.14%) was relatively common, whereas using health apps (39.53%) and using a digital device to track health metrics (35.37%) or health goal progress (38.99%) were less common. Digitally communicating with one's health care providers (35.58%) was moderate, whereas sharing health data with providers (17.20%) and sharing health information on social media (14.02%) were uncommon. Being female, younger than 65 years, a college graduate, and a smart device owner positively predicted several digital health engagement behaviors (odds ratio range = 0.09-4.21; P value range < .001-.03). Conclusions. Many public health goals depend on a digitally engaged populace. These data highlight potential barriers to 7 key digital engagement behaviors that could be targeted for intervention.

RESUMO

National health goals include assessing and improving mental health in understudied US populations. We surveyed 274 individuals (18-35 years old) of Hispanic/Latino/Spanish origin residing in the United States. Participants reported poor general mental health compared with Healthy People goals. Stress was negatively associated and perceived supportive communication was positively associated with mental health. A 3-way interaction showed perceived supportive communication mitigated the negative effect of stress on mental health, and perceptions of tangible support without supportive communication degraded overall mental health. Theoretical and practical implications for social support and Hispanic population mental health are discussed.

RESUMO

Whether a loss or gain frame has a persuasive advantage in communicating health risks is a matter of ongoing debate. Findings reported in the literature are mixed, suggesting that framing effects are likely complex and may be influenced by a combination of factors. This study examined reactance as a mediator and dose as a moderator of loss/gain framing effects. Adults (N = 1,039) read framed messages about the health consequences of physical (in)activity in varying message doses (i.e., number of framed statements). Compared to loss frames, gain frames generated more threat to freedom and reactance. Dosage exerted significant influence at the extremes; the one-dose messages invoked less intentions to exercise compared to the four-dose messages. Planned contrasts revealed significant frame × dose interactions. Notably, the one-dose gain-framed messages triggered significantly more freedom threat and less intentions to engage in physical activity-a situation that changed when the information was loss-framed or when the dosage was increased.

RESUMO

OBJECTIVE: To characterise how online media coverage of journal articles on cancer funded by the US government varies by cancer type and stage of the cancer control continuum and to compare the disease prevalence rates with the amount of funded research published for each cancer type and with the amount of media attention each receives. DESIGN: A cross-sectional study. SETTING: The United States. PARTICIPANTS: The subject of analysis was 11 436 journal articles on cancer funded by the US government published in 2016. These articles were identified via PubMed and characterised as receiving online media attention based on data provided by Altmetric. RESULTS: 16.8% (n=1925) of articles published on US government-funded research were covered in the media. Published journal articles addressed all common cancers. Frequency of journal articles differed substantially across the common cancers, with breast cancer (n=1284), lung cancer (n=630) and prostate cancer (n=586) being the subject of the most journal articles. Roughly one-fifth to one-fourth of journal articles within each cancer category received online media attention. Media mentions were disproportionate to actual burden of each cancer type (ie, incidence and mortality), with breast cancer articles receiving the most media mentions. Scientific articles also covered the stages of the cancer continuum to varying degrees. Across the 13 most common cancer types, 4.4% (n=206) of articles focused on prevention and control, 11.7% (n=550) on diagnosis and 10.7% (n=502) on therapy. CONCLUSIONS: Findings revealed a mismatch between prevalent cancers and cancers highlighted in online media. Further, journal articles on cancer control and prevention received less media attention than other cancer continuum stages. Media mentions were not proportional to actual public cancer burden nor volume of scientific publications in each cancer category. Results highlight a need for continued research on the role of media, especially online media, in research dissemination.

RESUMO

Effective use of genetic and genomic data in cancer prevention and treatment depends on adequate communication with patients and the public. Although relevant empirical work has emerged, the scope and outcomes of this communication research have not been characterized. We conducted a comprehensive scoping review of recent published research (2010-2017) on communication of cancer-related genetic and genomic testing (CGT) information. Searches in six databases revealed 9243 unique records; 513 papers were included. Most papers utilized an observational quantitative design; fewer utilized an experimental design. More attention has been paid to outcomes of CGT results disclosure than to decision making regarding CGT uptake or the process of results disclosure. Psychosocial outcomes were most common across studies. This literature has a strong focus on BRCA1/2, with few papers focused on Lynch syndrome or next-generation technologies. Women, Caucasians, older adults, and those of higher socioeconomic status were overrepresented. Research gaps identified include the need for studies on the process of CGT communication; examining behavioral, decision making, and communication outcomes; and inclusion of diverse populations. Addressing these gaps can help improve the use of genomics in cancer control and reduce disparities in access to and use of CGT.

RESUMO

Precision medicine (PM) draws upon individual biological and psychosocial factors to create a personalized approach to healthcare. To date, little is known about how healthcare consumers will respond to such highly personalized guidance and treatment. The assumption is that responses will generally be favorable; yet in the media and in online public discussions about PM, concerns have been raised about invasions of privacy and autonomy. Findings from the tailoring literature-relevant because PM is, in a sense, "hypertailoring"-similarly suggest a potential for provoking unintended consequences such as personalization reactance, wherein perceived threat to one's privacy or freedom can lead to rejection of the personalized message or its source. Here, we review extant tailoring and other relevant research to identify challenges that could arise in PM communication. We then draw upon a patient-centered communication perspective to highlight elements of the communication process wherein resistance could be mitigated. This review aims to provide preliminary guidance for practitioners when communicating with patients and healthcare consumers about PM, as well as point scholars toward fruitful topics for research in this emerging health communication area.

RESUMO

Skin self-examination (SSE) consists of routinely checking the body for atypical moles that might be cancerous. Identifying atypical moles is a visual task; thus, SSE training materials utilize pattern-focused visuals to cultivate this skill. Despite widespread use, researchers have yet to explicate how pattern-focused visuals cultivate visual skill. Using eye tracking to capture the visual scanpaths of a sample of laypersons (N = 92), the current study employed a 2 (pattern: ABCDE vs. ugly duckling sign [UDS]) × 2 (presentation: photorealistic images vs. illustrations) factorial design to assess whether and how pattern-focused visuals can increase layperson accuracy in identifying atypical moles. Overall, illustrations resulted in greater sensitivity, while photos resulted in greater specificity. The UDS × photorealistic condition showed greatest specificity. For those in the photo condition with high self-efficacy, UDS increased specificity directly. For those in the photo condition with self-efficacy levels at the mean or lower, there was a conditional indirect effect such that these individuals spent a larger amount of their viewing time observing the atypical moles, and time on target was positively related to specificity. Illustrations provided significant gains in specificity for those with low-to-moderate self-efficacy by increasing total fixation time on the atypical moles. Findings suggest that maximizing visual processing efficiency could enhance existing SSE training techniques.

RESUMO

BACKGROUND/AIMS: Public understanding of the role of genetics in disease risk is key to appropriate disease prevention and detection. This study assessed the current extent of awareness and use of genetic testing in the US population. Additionally, the study identified characteristics of subgroups more likely to be at risk for low genetic literacy. METHODS: The study used data from the National Cancer Institute's 2017 Health Information National Trends Survey, including measures of genetic testing awareness, genetic testing applications and genetic testing usage. Multivariable logistic regression models estimated associations between sociodemographics, genetic testing awareness, and genetic testing use. RESULTS: Fifty-seven percent of respondents were aware of genetic tests. Testing awareness differed by age, household income, and race/ethnicity. Most participants had heard of using tests to determine personal disease risk (82.58%) or inherited disease risk in children (81.41%), but less were familiar with determining treatment (38.29%) or drug efficacy (40.76%). Among those with genetic testing awareness, actual testing uptake was low. CONCLUSIONS: A large portion of the general public lacks genetic testing awareness and may benefit from educational campaigns. As precision medicine expands, increasing public awareness about genetic testing applications for disease prevention and treatment will be important to support population health.
