Breathing on the job: investigating predictors of air quality protective actions and information seeking among outdoor workers.

BACKGROUND: Air quality issues, exacerbated by wildfire smoke and excessive ozone that is worsened by climate change, pose significant health risks to outdoor workers, who are often overlooked in regulatory protection and communication efforts. This study examined how outdoor worker demographics, risk perceptions, and efficacy beliefs predict air quality protective actions and information seeking. Additionally, it investigates the sources of information that this population relies on for understanding air quality. METHOD: A survey was conducted with 256 outdoor workers in Colorado, a state regularly affected by wildfire smoke and ozone. Measures included demographics, perceived risk, efficacy beliefs, air quality actions, and information seeking behavior. RESULTS: Both perceived risk and efficacy beliefs influenced health-protective actions during poor air quality events. Interestingly, efficacy beliefs were found to be a more reliable predictor of air quality information seeking than perceived risk. The top sources of air quality information among outdoor workers were local news media, The Weather Channel, mobile apps, state public health authorities, and the National Weather Service. CONCLUSIONS: These findings enhance our understanding of how perceived risk and efficacy beliefs promote health-protective behaviors among outdoor workers. They lay the groundwork for future research and initiatives to improve air quality communication and promote health-protective actions for this population group. Promoting the efficacy of health-protective actions and seeking information are important components of air quality communication.

The Social Ecology of Health Beliefs and Misinformation Framework: Examining the impact of misinformation on vaccine uptake through individual and sociological factors.

BACKGROUND: Misinformation presents a critical concern for academic and public health discourse, particularly around vaccine response. Before the COVID-19 pandemic, vaccine hesitancy was responsible for decreased immunization uptake for vaccine-preventable diseases. Misinformation connected to the novel COVID-19 vaccine has further fueled vaccine hesitancy in Colorado and the United States. Our study brings together three different perspectives - physicians, public health professionals, and parents - to understand the impact of misinformation on vaccine uptake in Colorado. Our study proposes a framework for combining the Health Belief Model with the Socio-Ecological model to account for societal factors in healthcare decision making. METHODS: Semi-structured interviews and focus groups with public health professionals, physicians, and parents (n = 31) were conducted in late spring and summer 2022. Data were coded inductively using thematic analysis. Identified themes were deductively categorized according to the Socio-Ecological Model and Health Belief Model. RESULTS: Using a theoretical framework that combined the Health Belief Model and the Socio-Ecological Model, we identified seven factors that influenced vaccine hesitancy in Colorado. Intrapersonal factors included routine vaccine hesitancy connected to perceptions of severity and susceptibility, efficacy, and benefits and barriers to vaccine uptake; interpersonal factors included social networks; institutional factors included mass mediated platforms, portrayals of uncertainty, distrust in institutional sources of information, and political influences in vaccine decision making; and structural factors included economic barriers behind vaccine hesitancy. CONCLUSIONS: Our study provides a unique, triangulated, post-positivist perspective on the role of misinformation in vaccine hesitancy in Colorado. The findings provide evidence that misinformation is an important barrier to vaccination uptake and can permeate multiple socio-ecological determinants/characteristics to influence vaccination behaviors including intrapersonal, interpersonal, institutional, and structural levels. We introduce the Social Ecology of Health Beliefs and Misinformation Framework to account for how misinformation may interrupt vaccine uptake.

Scientists' deficit perception of the public impedes their behavioral intentions to correct misinformation.

This paper investigates the relationship between scientists' communication experience and attitudes towards misinformation and their intention to correct misinformation. Specifically, the study focuses on two correction strategies: source-based correction and relational approaches. Source-based approaches combatting misinformation prioritize sharing accurate information from trustworthy sources to encourage audiences to trust reliable information over false information. On the other hand, relational approaches give priority to developing relationships or promoting dialogue as a means of addressing misinformation. In this study, we surveyed 416 scientists from U.S. land-grant universities using a self-report questionnaire. We find that scientists' engagement in science communication activities is positively related to their intention to correct misinformation using both strategies. Moreover, the scientists' attitude towards misinformation mediates the relationship between engagement in communication activities and intention to correct misinformation. The study also finds that the deficit model perception-that is, the assumption that scientists only need to transmit scientific knowledge to an ignorant public in order to increase understanding and support for science-moderates the indirect effect of engagement in science communication activities on behavioral intention to correct misinformation using relational strategies through attitude towards misinformation. Thus, the deficit model perception is a barrier to engaging in relational strategies to correct misinformation. We suggest that addressing the deficit model perception and providing science communication training that promotes inclusive worldviews and relational approaches would increase scientists' behavioral intentions to address misinformation. The study concludes that scientists should recognize their dual positionality as scientists and members of their community and engage in respectful conversations with community members about science.

Comparing local TV news with national TV news in cancer coverage: an exploratory content analysis.

The authors compared local TV news with national TV news in terms of cancer coverage using a nationally representative sample of local nightly TV and national network TV (i.e., ABC, CBS, NBC, and CNN) cancer news stories that aired during 2002 and 2003. Compared with national TV news, local TV cancer stories were (a) much shorter in length, (b) less likely to report on cancer prevention (i.e., preventive behaviors and screening tests), and (c) less likely to reference national organizations (i.e., National Cancer Institute, American Cancer Society, National Institutes of Health, Centers for Disease Control and Prevention, Food and Drug Administration) that have made clear recommendations about ways to prevent cancer. The implications of these findings for health communication research and cancer education were discussed.

Effects of responsibility attribution and message source on young adults' health attitudes and behaviors.

This study investigated the effect of message attributes on responses to health messages. The authors examined 3 variables--responsibility attribution (individual vs. social), source (personal blog vs. online magazine), and illness (stigmatized vs. nonstigmatized)--for effects on young adults' health-related attitudes and behaviors. Responsibility attributions influenced attitudes about individual responsibility for health but did not alter participants' behavioral intentions. Further, individuals exposed to a story from a health magazine exhibited stronger intentions to communicate about health than individuals exposed to a personal health blog. Although women's attitudes regarding social responsibility for health did not differ by illness type or responsibility attribution, men's attitudes did.

The effect of food label cues on perceptions of quality and purchase intentions among high-involvement consumers with varying levels of nutrition knowledge.

OBJECTIVE: To determine whether differences in nutrition knowledge affected how women (a high-involvement group) interpreted intrinsic cues (ingredient list) and extrinsic cues ("all natural" label) on food labels. METHODS: A 2 (intrinsic cue) × 2 (extrinsic cue) × 2 (nutrition knowledge expert vs novice) within-subject factorial design was used. Participants were 106 female college students (61 experts, 45 novices). Dependent variables were perception of product quality and purchase intention. RESULTS: As predicted by the elaboration likelihood model, experts used central route processing to scrutinize intrinsic cues and make judgments about food products. Novices used peripheral route processing to make simple inferences about the extrinsic cues in labels. CONCLUSIONS AND IMPLICATIONS: Consumers' levels of nutrition knowledge influenced their ability to process food labels. The United States Food and Drug Administration should regulate the "all natural" food label, because this claim is likely to mislead most consumers.

A content analysis of cancer survivorship coverage in a representative sample of US news outlets.

BACKGROUND: Media are popular sources of cancer information, yet little is known about how survivors are depicted. METHODS: This study analyzes coverage of cancer survivors in a nationally representative sample of newspapers and television newscasts. Stories were coded for cancer type, gender, age, survivorship length and status, treatment types, and spirituality, among other variables. RESULTS: Media provide limited information about survivors. Also, although breast cancer coverage was close to survivorship rates, nearly every other cancer type was underreported for both incidence and survivorship rates. CONCLUSIONS: Inaccurate media coverage may be contributing to public misunderstanding about cancer survivorship.

The Relationship Between Editorial and Advertising Content about Tobacco and Alcohol in United States Newspapers.

Using a nationally representative sample, this study examined the relationship between amount of alcohol and tobacco advertising and related news-editorial content. This study found less tobacco and alcohol advertising in newspapers than did previous research and no relationship between coverage and number of advertisements.

Newspaper Coverage of Cancer Prevention: Multilevel Evidence for Knowledge Gap Effects.

Prior research on knowledge gap effects, in health as well as in other domains, has focused largely on assessing individual-level differences in exposure to news based on self-report of media use. Inherent inferential limitations of this approach are addressed by testing the hypothesis that the relationship between education and cancer prevention knowledge will be moderated by regional differences in U.S. news coverage of cancer prevention. The study also tests, using these methods, findings by Kwak (1999) suggesting that the importance of attention to relevant news in predicting knowledge decreases as information available in the news increases. Using a representative national sample of newspaper coverage to assess regional differences in cancer prevention coverage, a representative national probability sample to assess respondent education and cancer prevention knowledge, and multilevel analyses of the relationship between regional coverage differences and knowledge of persons in those regions, support is found for both of these propositions.

News coverage of cancer in the United States: a national sample of newspapers, television, and magazines.

A content analysis of cancer news coverage in a sample of local and national newspapers, television, and magazines was conducted for the years 2002 and 2003. Analyses compared proportions of mentions of cancer sites with proportional contribution to cancer incidence and mortality based on available epidemiological estimates. Analyses also examined relative attention provided to prevention, detection, treatment, causes, and outcomes of various cancers. Results indicated that coverage reflected incidence rates more closely than they did mortality rates, but in both cases coverage under-represented the contribution of lung cancer to morbidity and mortality and over-represented the contribution of breast cancer. Of greater public health concern was the limited coverage of prevention and detection even for highly preventable or relatively easily detected cancers. Implications of findings are discussed.

Alcohol, illegal drugs, violent crime, and traffic-related and other unintended injuries in U.S. local and national news.

OBJECTIVE: The present study seeks to establish the extent to which media coverage acknowledges alcohol's contribution to violent crime as well as to motor vehicle injuries and other injury incidents. METHOD: The study content-analyzes a unique sample, closely approximating national representativeness, of local and national television news, local newspapers, and national magazines randomly sampled during a 2-year period. RESULTS: Alcohol's role in violent crime and, to a lesser extent, in motor vehicle and other injury incidents is underreported relative to available estimates regarding alcohol-attributable fractions. Relative frequency of various news frames for coverage of alcohol and illegal drugs and differences in coverage of alcohol and illegal drugs as a function of the type of story and news medium are described. CONCLUSIONS: The underreporting in the United States of alcohol's contribution to serious and fatal injury from these causes may reduce public perceptions of alcohol-related risks, potentially influencing behavior, including public support of alcohol-control policies. This provides an opportunity for media-advocacy approaches to improve public health content of news coverage.

US news media coverage of tobacco control issues.

OBJECTIVE: To characterise the relative amount and type of daily newspaper, local and national TV newscast, and national news magazine coverage of tobacco control issues in the United States in 2002 and 2003. DESIGN: Content analysis of daily newspapers, news magazines, and TV newscasts. SUBJECTS: Items about tobacco in daily newspapers, local and national TV newscasts, and three national news magazines in a nationally representative sample of 56 days of news stratified by day of week and season of the year, from 2002 and 2003. MAIN OUTCOME MEASURES: Story theme, tobacco topics, sources, story prominence, story valence (orientation), and story type. RESULTS: Tobacco coverage was modest over the two-year period as estimated in our sample. Only 21 TV stories, 17 news magazine stories, and 335 daily newspaper stories were found during the two-year sampling period. Noteworthy results for the newspaper data set include the following: (1) government topics predominated coverage; (2) government action and negative health effects topics tended not to occur together in stories; (3) tobacco stories were fairly prominently placed in newspapers; (4) opinion news items tended to favour tobacco control policies, while news and feature stories were evenly split between positive and negative stories; and (5) tobacco coverage in the southeast, which is the country's major tobacco producing region, did not differ from the rest of the country. CONCLUSION: Results suggest mixed support in news coverage for tobacco control efforts in the United States. The modest amount of news coverage of tobacco is troubling, particularly because so few news stories were found on TV, which is a more important news source for Americans than newspapers. When tobacco was covered, government themed stories, which often did not include mentions of negative health effects, were typical, suggesting that media coverage does not reinforce the reason for tobacco control efforts. However, some results were encouraging. For example, when newspapers did cover tobacco, they accorded the stories relatively high prominence, thus increasing the chance that readers would see tobacco stories when they were published.

Scientese and ambiguous citations in the selling of unproven medical treatments.

Unproven medical treatments are widely marketed, and are especially accessible via the Internet. Little is known about factors that may increase the persuasiveness of information used to promote such unproven treatments. This article examines the effect of scientese (use of scientific jargon) and attributed versus unattributed citations on message persuasiveness on science and nonscience majors. Scientese, as expected, increased message persuasiveness. Contrary to expectations, this effect was not moderated by science versus nonscience major, graduate versus undergraduate status, or potential involvement with the message topic. In addition, no effect was found for attributed versus unattributed citations either as a main effect or in interaction with science major, graduate or undergraduate status, or for an indicator of involvement with the health topic. These findings are consistent with Food and Drug Administration concerns about the ability of the public to critically discern the quality of evidence supporting use of unproven remedies and dietary supplements. Similarly, they raise questions about the judicial reasoning that presumes consumers can make such judgments, though replication with clinical populations would be desirable to strengthen policy-relevant inferences.
