RESUMEN

Few case studies exist in the public health or design literatures showing how to create national scale messaging campaigns in low-income countries using design processes. In this paper, we describe how we used Behaviour Centred Design to develop Nyumba ni choo, the Tanzanian National Sanitation Campaign. The process involved multiple iterations of ideation and filtration by professional creatives, government staff, academics and sanitation specialists to create a branded mass communication campaign, which was refreshed annually. The campaign was based on the insight that Tanzania is modernizing rapidly, with people upgrading their homes, but leaving their outside toilets in a 'traditional' state. Built around the 'big idea' that a household is not fully modern without a good-quality, modern toilet, the campaign employed reality TV shows, live engagements and mass and digital media postings, all targeted at motivating both the government and general population to improve toilets. The campaign has made toilets a topic of national conversation and has led to a major uptick in the rate of toilet building. Efforts to improve public health-related behaviour can be enhanced by using systematic approaches that build on available evidence, understand behaviour in its common settings, employ psychological theory and engage creative expertise.

RESUMEN

BACKGROUND: Various trainings are designed to educate nurses to become simulation educators. However, there are no good strategies to sustain their learnings and keep them engaged. We developed a series of 10 interactive digital storytelling comic episodes 'The Adventures of Super Divya (SD)' to strengthen simulation educator's facilitation knowledge, skills, confidence, and engagement. This endline evaluation presents results on the change in knowledge after watching the episodes and retention of that knowledge over 10 months. OBJECTIVES: The objectives of this pilot study are to: 1) assess the change in knowledge between the baseline and post-episode surveys; and 2) understand the retention of knowledge between the post-episode and the endline survey. METHODS: A human-centred design was used to create the episodes grounded in the lived experience of nurse simulation educators. The heroine of the comic is Divya, a 'Super Facilitator' and her nemesis is Professor Agni who wants to derail simulation as an educational strategy inside obstetric facilities. Professor Agni's schemes represent real-life challenges; and SD uses effective facilitation and communication to overcome them. The episodes were shared with a group of nurse mentors (NM) and nurse mentor supervisors (NMS) who were trained to be champion simulation educators in their own facilities. To assess change in knowledge, we conducted a baseline, nine post-episode surveys and an endline survey between May 2021 and February 2022. RESULTS: A total 110 NM and 50 NMS watched all 10 episodes and completed all of the surveys. On average, knowledge scores increased by 7-9 percentage points after watching the episodes. Comparison of survey responses obtained between 1 and 10 months suggest that the gain in knowledge was largely retained over time. CONCLUSIONS: Findings suggest that this interactive comic series was successful in a resource limited setting at engaging simulation educators and helped to maintain their facilitation knowledge over time.

RESUMEN

BACKGROUND: Previous studies have found that the dissemination pattern and delivery mechanism of information can provide crucial resources and empowerment for individuals to the promotion of health literacy. The present study investigates how health information sources are associated with health literacy among older adults in west China, and tries to explain the mechanisms underlying the link between health information sources and health literacy in the Chinese context. METHODS: The cross-sectional study employed a representative sample of 812 urban citizens aged 60 and older in 2017 in Western China. RESULTS: We found that health information sources including healthcare practitioners (B = 4.577, p < 0.001), neighbors (B = 2.545, p < 0.05), newspapers (B = 4.280, p < 0.001), and television (B = 4.638, p < 0.001) were positively associated with health literacy. Additionally, age (B = -1.781, p < 0.001) was negatively associated with health literacy, and the socio-economic status factors including minority (B = -10.005, p < 0.001), financial strain status of perceived very difficult (B = -10.537, p < 0.001), primary school (B = 11.461, p < 0.001), junior high school (B = 18.016, p < 0.001), polytechnic school or senior high school (B = 21.905, p < 0.001), college and above (B = 23.433, p < 0.001) were significantly linked to health literacy, and suffering from chronic diseases (B = 3.430, p < 0.01) was also positively related to health literacy. CONCLUSIONS: Health information sources including healthcare practitioners, neighbors, newspapers, and television have a strong influence on health literacy, which implies that the four main types of sources are the important patterns of health information dissemination in the reinforcement of health literacy. In addition, the present findings also indicate age, minority and disease differences in health literacy and confirm the influence of enabling factors including educational attainment and financial strain on health literacy. Based on these findings and their implications, specific evidence is presented for the reinforcement of health literacy in interpersonal and mass communication, and in the educational and financial settings in the Chinese context. The present results also suggest that the age-specific, minority-specific and disease-specific measures should be taken to promote health literacy among older adults.

RESUMEN

This study aimed to delineate the decline in public interest toward the March 2011 Great East Japan Earthquake (GEJE) and the Fukushima Daiichi nuclear power plant (FNPP) accident in Japan over a ten-year period. In this longitudinal descriptive study, we searched for publications within a ten-year period in Letters to the Editor that mentioned the GEJE, the FNPP accident, or the January 1995 Great Hanshin-Awaji Earthquake (GHAE) that occurred in Japan, using the official databases of the three largest Japanese newspapers. The GEJE- and GHAE-related publications (4,809 and 2,092, respectively) are depicted as scatter plots. The results show a gradual decrease in the publications mentioning GEJE or GHAE. The impact of GEJE and FNPP on Japanese society was enormous, but the public interest waned over time. Communication strategies that maintain a high public interest in previous disasters may be necessary.

RESUMEN

In today's vast digital landscape, people are constantly exposed to threatening language, which attracts attention and activates the human brain's fear circuitry. However, to date, we have lacked the tools needed to identify threatening language and track its impact on human groups. To fill this gap, we developed a threat dictionary, a computationally derived linguistic tool that indexes threat levels from mass communication channels. We demonstrate this measure's convergent validity with objective threats in American history, including violent conflicts, natural disasters, and pathogen outbreaks such as the COVID-19 pandemic. Moreover, the dictionary offers predictive insights on US society's shifting cultural norms, political attitudes, and macroeconomic activities. Using data from newspapers that span over 100 years, we found change in threats to be associated with tighter social norms and collectivistic values, stronger approval of sitting US presidents, greater ethnocentrism and conservatism, lower stock prices, and less innovation. The data also showed that threatening language is contagious. In all, the language of threats is a powerful tool that can inform researchers and policy makers on the public's daily exposure to threatening language and make visible interesting societal patterns across American history.

RESUMEN

Background: Amid the COVID-19 pandemic, social media have influenced the circulation of health information. Public health agencies often use Twitter to disseminate and amplify the propagation of such information. Still, exposure to local government-endorsed COVID-19 public health information does not make one immune to believing misinformation. Moreover, not all health information on Twitter is accurate, and some users may believe misinformation and disinformation just as much as those who endorse more accurate information. This situation is complicated, given that elected officials may pursue a political agenda of re-election by downplaying the need for COVID-19 restrictions. The politically polarized nature of information and misinformation on social media in the United States has fueled a COVID-19 infodemic. Because pre-existing political beliefs can both facilitate and hinder persuasion, Twitter users' belief in COVID-19 misinformation is likely a function of their goal inferences about their local government agencies' motives for addressing the COVID-19 pandemic. Objective: We shed light on the cognitive processes of goal understanding that underlie the relationship between partisanship and belief in health misinformation. We investigate how the valence of Twitter users' goal inferences of local governments' COVID-19 efforts predicts their belief in COVID-19 misinformation as a function of their political party affiliation. Methods: We conducted a web-based cross-sectional survey of US Twitter users who followed their state's official Department of Public Health Twitter account (n=258) between August 10 and December 23, 2020. Inferences about local governments' goals, demographics, and belief in COVID-19 misinformation were measured. State political affiliation was controlled. Results: Participants from all 50 states were included in the sample. An interaction emerged between political party affiliation and goal inference valence for belief in COVID-19 misinformation (∆R 2=0.04; F 8,249=4.78; P<.001); positive goal inference valence predicted increased belief in COVID-19 misinformation among Republicans (ß=.47; t 249=2.59; P=.01) but not among Democrats (ß=.07; t 249=0.84; P=.40). Conclusions: Our results reveal that favorable inferences about local governments' COVID-19 efforts can accelerate belief in misinformation among Republican-identifying constituents. In other words, accurate COVID-19 transmission knowledge is a function of constituents' sentiment toward politicians rather than science, which has significant implications on public health efforts for minimizing the spread of the disease, as convincing misinformed constituents to practice safety measures might be a political issue just as much as it is a health one. Our work suggests that goal understanding processes matter for misinformation about COVID-19 among Republicans. Those responsible for future COVID-19 public health messaging aimed at increasing belief in valid information about COVID-19 should recognize the need to test persuasive appeals that address partisans' pre-existing political views in order to prevent individuals' goal inferences from interfering with public health messaging.

RESUMEN

Social media is a common, multi-purpose tool used by most hospitals to engage a broad audience. The relationship between hospital social media activity and performance on influential reputation and patient experience ratings is not well described. The aim of this study was to characterize social media activity across the top 100 revenue grossing U.S. hospitals and its impact on key patient experience and hospital rankings. While nearly all top 100 revenue grossing U.S. hospitals have a presence on social media, usage and following significantly varied. Social media activity metrics collected showed some limited association with reputation and patient experience-influenced rankings.

RESUMEN

Resumo O artigo apresenta um panorama da Agência Nacional de Vigilância Sanitária (Anvisa) na imprensa brasileira. A amostra é composta por textos publicados em 2018 em diferentes veículos impressos e on-line, totalizando 1.629 publicações de 148 veículos de comunicação distintos. A partir da análise de conteúdo, observou-se que a Anvisa não é a principal fonte na maior parte dos textos sobre vigilância sanitária na imprensa, bem como não é apresentada como órgão do Sistema Único de Saúde (SUS), e que os principais temas pautados no período foram relacionados à regulamentação, aos registros e às autorizações. Dentre os assuntos sob sua responsabilidade, o mais frequente foi relacionado à área de medicamentos e farmacopeia. O mês de julho registrou uma frequência maior de textos devido à repercussão nacional do caso da morte da paciente de um cirurgião plástico e influenciador digital pelo uso de um produto autorizado pela agência. É importante que a Anvisa reveja o seu posicionamento junto à imprensa, ampliando nos meios de comunicação o seu espaço de fala como protagonista da vigilância sanitária brasileira. Os resultados da análise sugerem tendências da cobertura nacional e podem ajudar a melhorar as estratégias de comunicação não só da Anvisa, mas também de outros órgãos de saúde .

Abstract The article presents an overview of the Brazilian media coverage of the Brazilian Health Regulatory Agency (ANVISA). The sample consists of texts published in different print and online media throughout 2018, totaling 1,629 publications from 148 different media. Data underwent content analysis, showing that most texts on health surveillance in the press do not approach ANVISA as the main source nor as a body of the Brazilian Unified Health System (SUS). The main themes in the period were related to regulation, records, and authorizations. Among the subjects under the ANVISA responsibility, the most frequent were related to medication and pharmacopoeia. Given the national repercussion involving the death of a patient of a plastic surgeon and digital influencer due to the use of a product authorized by the agency, most publications date from July. ANVISA should review its positioning with the press, expanding its role as a protagonist of the Brazilian health surveillance in the media. The results suggest trends in national coverage and may help improving the communication strategies not only of ANVISA, but also of other health institutions.

RESUMEN

A pesquisa analisa a produção de conteúdos sobre arboviroses na fanpage do Ministério da Saúde do Brasil antes, durante e após a epidemia de Zika vírus, com estudo de métodos mistos englobando análise do conteúdo divulgado entre 2015 e 2017 e o Discurso do Sujeito Coletivo (DSC) dos trabalhadores que produziam os conteúdos. Dos 5.732 posts coletados, 649 deles eram sobre arboviroses, com enfoque maior relacionado à prevenção e à Zika. O Sistema Único de Saúde (SUS) aparece em pequena parte da amostra. Há preocupação em comunicar saúde com qualidade e respaldo técnico, mas diferenças na linguagem do especialista e no timming entre o que é publicado on-line e o repassado aos serviços de saúde ocasionam ruídos. O discurso é transmissional, apresentando ausência de diálogo com a população, subestimando o potencial que a rede social tem para interação, compartilhamento e engajamento.(AU)

La investigación analiza la producción de contenidos sobre arbovirosis en la fanpage del Ministerio de Salud de Brasil antes, durante y después de la epidemia de Zika virus, con estudio de métodos mixtos englobando análisis del contenido divulgado entre 2015 y 2017 y el discurso del sujeto colectivo de los trabajadores que producían los contenidos. De los 5.732 posts colectados, 649 eran sobre arbovirosis, en un enfoque mayor relacionado a la prevención y al Zika. El Sistema Único de Salud aparece en una pequeña parte de la muestra. Existe la preocupación de comunicar salud con calidad y respaldo técnico, pero diferencias en el lenguaje del especialista y en el timing entre lo que se publica online y lo que se traspasa a los servicios de salud causan ruidos. El discurso es de transmisión, con ausencia de diálogo con la población, subestimando el potencial que la red social tiene para la interacción, compartición y compromiso.(AU)

This study analyses the content production about arboviruses on the fan page of the Brazilian Ministry of Health before, during and after the Zika virus epidemic. It uses a mixed methods study that comprises the content analysis released from 2015 to 2017 and the Collective Subject Discourse of the workers who produced the contents. The results show that 649 out of 5,732 posts collected addressed arboviruses, with a greater focus on prevention and Zika. The Brazilian National Health System (SUS) was found in a small part of the sample. There is a concern to inform about health with quality, but differences in the specialist's language and timing between what is published online and what is conveyed to technical health services cause communication noise. It is a transmissional discourse, with no dialogue with the population, underestimating the potential of social media for interaction, sharing and engagement.(AU)

RESUMEN

The spread of misinformation, facilitated by social media and other digital platforms, has proven to be as destructive to global public health as the SARS-CoV-2 virus itself. Fake news adds challenges to human communication efforts, producing tension, misunderstanding, and disbelief. While social platforms such as Facebook, Twitter, Instagram, and Viber, etc. have provided a huge relief during the lockdown helping reduce mental stress and depression as well as facilitating online education, and work from home during the COVID-19 pandemic, it has also raised concerns over the spread of fake news. In such a situation, online fake news poses a new threat to public health communication as more people now depend on the internet to get health-related information. In response, this study seeks to understand how manipulation of news on social media has posed a threat to Fijian public health. Eventually, some of these have resulted in police investigations.

RESUMEN

Alcohol consumption in Germany continues to be high relative to its European neighbors. A long-term reduction of alcohol consumption can result in a reduction of the morbidity and mortality associated with alcohol. For many years now, the Federal Centre for Health Education (BZgA) has directed its focus in the field of addiction prevention on alcohol prevention and implemented three national multilevel campaigns intended for this target group. "Null Alkohol - Voll Power" (No Alcohol - Full Power) addresses adolescents between the ages of 12 and 16 and the campaign "Alkohol? Kenn dein Limit." (Alcohol? Know Your Limit.) comprises two separate campaigns dedicated to adults and 16- to 20-year-olds, respectively. Further, the BZgA provides sports clubs with the opportunity to participate in a program entitled "Alkoholfrei Sport genießen" (Enjoying Sports Without Alcohol). In this contribution, these measures and their foundational concepts are presented.The campaigns are interconnected to form a prevention chain that serves to bundle the individual efforts. All are based on the principles of social marketing and are continually quality checked. At the center of these efforts lies internet communication, complemented by direct communication in the lives of the target groups as well as mass communication in the form of billboards, TV and radio spots, ads, and print media. The BZgA is able to implement these programs in schools, clubs, and at the municipal level because of the good cooperation and coordination it maintains with the individual federal states. For decades now, the BZgA has conducted monitoring in the form of regular representative surveys, among others, on the subject of alcohol consumption behavior among 12- to 25-year-olds in Germany. The results show that although overall alcohol consumption may be on the decline over the long term, it still remains high.

RESUMEN

Communication campaigns can contribute to promoting physical activity (PA) among children. However, health inequalities can ensue from this type of public health intervention. Using a pre-test posttest design, we examined the effects of social disadvantage on the large-scale WIXX communication campaign and whether or not social disadvantage moderated WIXX's impact on PA. Parents of youths were identified using random digit dialing procedures and asked permission for their child to participate in a telephone survey. Surveys were conducted each year between 2012 and 2016. Moderating effects of individual-level and area-based indicators of social disadvantage on campaign effectiveness were examined. Self-reported levels of PA and trying new PAs were the outcomes. Exposure was defined as a function of ads recall and brand awareness. Logistic regression analyses controlling for survey periods, screen time, language, school grade, and attitudes toward PA were performed in 2020. Among girls, no significant interaction effects were observed for household income, parental education, and material deprivation. A significant interaction effect was observed for minority group status on PA (OR = 2.4; 95%CIs: 1.2, 4.9) and trying of new activities (OR = 2.5; 95%CIs: 1.2, 5.1). A significant interaction effect between social deprivation and exposure was observed for trying new activities among girls (OR = 1.8; 95%CIs: 1.0, 3.2). Among boys, no significant interaction effects were observed for any indicators. Results suggest no clear evidence of communication inequalities as a result of the WIXX campaign but reveal positive impacts of the campaign among more socially disadvantaged girls.

RESUMEN

As a crucial element of China's political and cultural life, "banners," or biaoyǔ, have been around for decades, in support of national-level policies such as family planning and the governing mottos of Presidents. The banners that have emerged during the Covid-19 pandemic which was also the subject of a national-level driven policy, have been involved in a nation-wide public debate over the language styles of banners used to urge people to stay indoors. Based on the analysis of the early COVID-19 banners and the related online comments, this article analyzes the language style patterns of the banners and the mode of banner circulation. The study found that the manner in which the banners are circulated goes beyond a unidirectional path of on-site instant communication. This process is facilitated by social networks and mass media, which, during circulation, twice created a banner upgrade. The upgrades created decontextualization and function extension of the banners, whereas audience feedback triggered an adaptive adjustment of the language style of the banners. This article suggests that the study of the use and spread of banners, especially the early COVID-19 banners, sheds light on the study of mass communication and discourse style, and also how measures to contain pandemics such as COVID-19 can be communicated.

RESUMEN

Due to changes in the information environment since the last global epidemic, high WHO officials have spoken about the need to fight not only the current COVID-19 pandemic but also the related infodemic. We thus explored how people search for information, how they perceive its credibility, and how all this relates to their engagement in self-protective behaviors in the crucial period right after the onset of COVID-19 epidemic. The online questionnaire was circulated within 48 h after the first case of COVID-19 was confirmed in Slovenia. We gathered information on participants' demographics, perception of the situation, their emotional and behavioral responses to the situation (i.e., self-protective behavior), perceived subjective knowledge, perceived credibility of different sources of information, and their level of trust. We looked into the relationships between perceived credibility and trust, and self-protective behavior of 1,718 participants and found that mass media, social media, and officials received relatively low levels of trust. Conversely, medical professionals and scientists were deemed the most credible. The perceived credibility of received information was linked not only with lower levels of negative emotional responses but also with higher adherence to much needed self-protective measures, which aim to contain the spread of the disease. While results might vary between societies with different levels of trust in relevant governmental and professional institutions, and while variances in self-protective behavior scores explained by our model are modest, even a small increase in self-protective behavior could go a long way in viral epidemics like the one we are facing today.

RESUMEN

INTRODUCTION AND AIMS: The recognition of the association between the use of alcohol and negative health outcomes have led to the endorsement of the World Health Organization's global strategy to reduce the harmful use of alcohol. Given the capacities, capabilities and sociocultural contexts of Thailand, this study aims to examine the Thai alcohol policy against the global strategy's recommended policy measures for marketing control and identify areas for further policy development. DESIGN AND METHODS: Semi-structured interviews were conducted with the stakeholders from three sectors: the government, academia and civil society. Their perceptions of the Thai alcohol policy in regulating alcohol industry's commercial strategies and activities were discussed. Audio data were transcribed verbatim, systematically coded and thematically analysed. RESULTS: Although the Thai Alcohol Control Act meticulously regulates the content of direct alcohol marketing, the volume of marketing and indirect alcohol marketing have become problematic and difficult for the government to address. The industry has worked to normalise the consumption of alcohol through repetitive brand exposure and their suggestion that drinking was integral for socialisation. The control of alcohol sponsorship was politically sensitive and legally ambiguous because alcohol sponsorship seemed to provide economic and social benefits and further reinforced the industry's positive image. DISCUSSION AND CONCLUSIONS: Despite the strict alcohol policy, gaps in the marketing regulations exist. Future policy development should place greater emphasis on alcohol sponsorship and branding through evidenced-based interventions. The interactions between the government and the industry should be monitored and restricted. Rigorous regulations, as seen for tobacco, are encouraged for alcohol marketing.

RESUMEN

People are exposed to persuasive communication across many different contexts: Governments, companies, and political parties use persuasive appeals to encourage people to eat healthier, purchase a particular product, or vote for a specific candidate. Laboratory studies show that such persuasive appeals are more effective in influencing behavior when they are tailored to individuals' unique psychological characteristics. However, the investigation of large-scale psychological persuasion in the real world has been hindered by the questionnaire-based nature of psychological assessment. Recent research, however, shows that people's psychological characteristics can be accurately predicted from their digital footprints, such as their Facebook Likes or Tweets. Capitalizing on this form of psychological assessment from digital footprints, we test the effects of psychological persuasion on people's actual behavior in an ecologically valid setting. In three field experiments that reached over 3.5 million individuals with psychologically tailored advertising, we find that matching the content of persuasive appeals to individuals' psychological characteristics significantly altered their behavior as measured by clicks and purchases. Persuasive appeals that were matched to people's extraversion or openness-to-experience level resulted in up to 40% more clicks and up to 50% more purchases than their mismatching or unpersonalized counterparts. Our findings suggest that the application of psychological targeting makes it possible to influence the behavior of large groups of people by tailoring persuasive appeals to the psychological needs of the target audiences. We discuss both the potential benefits of this method for helping individuals make better decisions and the potential pitfalls related to manipulation and privacy.

RESUMEN

OBJECTIVES: To improve the effectiveness of alcohol harm reduction mass media campaigns, this study aimed to (1) identify existing advertisements (ads) with greatest potential to motivate reduced alcohol consumption, (2) assess consistency across audience subgroups in ad effectiveness and (3) identify ad features associated with effectiveness. DESIGN: Cross-sectional online ad response study with random assignment to view ads. PARTICIPANTS: 2174 Australian adult weekly drinkers recruited from an online panel. PROCEDURE: Participants were randomly assigned to view three of 83 English-language alcohol harm reduction ads. Each ad was viewed and rated by a mean of 79 participants. OUTCOME MEASURE: After viewing each ad, participants reported the extent to which they felt motivated to reduce their drinking. Ads were ranked from most to least motivating using predicted means adjusted for demographic characteristics and alcohol consumption. We compared the characteristics of the top-ranked 15% of ads (most motivating) with the middle 70% and bottom 15%. RESULTS: An ad about the link between alcohol and cancer ('Spread') was most motivating, whereas an ad that encouraged drinking water instead of beer ('Add nothing') was least motivating. Top-ranked ads were more likely than other ads to feature a 'why change' message and less likely to carry a 'how to change' message; more likely to address long-term harms; more likely to be aimed at the general adult drinking population and more likely to include drinking guidelines. There was substantial overlap in top-ranked ads for younger versus older adults, men versus women and high-risk versus low-risk drinker subgroups. CONCLUSIONS: The effectiveness of alcohol harm reduction campaigns may be improved by directly communicating alcohol's long-term harms to the general adult population of drinkers along with drinking guidelines. By doing so, campaigns can also efficiently influence high-risk drinkers and key demographic subgroups.

RESUMEN

This study evaluated the effect of a 12-week social marketing intervention conducted in 2012 promoting 1% milk use relying on paid advertising. Weekly milk sales data by type of milk (whole, 2%, 1%, and nonfat milk) were collected from 80 supermarkets in the Oklahoma City media market, the intervention market, and 66 supermarkets in the Tulsa media market (TMM), the comparison market. The effect was measured with a paired t-test. A mixed segmented regression model, controlling for the contextual difference between supermarkets and data correlation, identified trends before, during, and after the intervention. Results show the monthly market share of 1% milk sales changed from 10.0% to 11.5%, a 15% increase. Evaluating the volume sold, the monthly mean number of gallons of 1% milk sold increased from 890.5 gal (SD = 769.8) per supermarket from before the intervention to 1070.7 gal (SD = 922.5) following the intervention (t(79) = 9.4, p = 0.000). Moreover, average weekly sales of 1% milk were stable prior to the intervention (b = - 0.2 gal/week, 95% CI [- 0.6 gal/week, 0.3 gal/week]). During each additional week of the intervention, 1% milk sales increased by an average of 4.1 gal in all supermarkets (95% CI [3.5 gal/week, 4.6 gal/week]). Three months later, albeit attenuated, a significant increase in 1% milk sales remained. In the comparison market, no change in the market share of 1% milk occurred. Paid advertising, using the principles of social marketing, can be effective in changing an entrenched and habitual nutrition habit.

RESUMEN

The accident at Fukushima Daiichi nuclear power plant in the wake of the Great East Japan Earthquake received considerable media coverage. However, a leaning towards sensationalism and a proclivity for denouncing those in power resulted in articles that were, in several instances, scientifically inaccurate, causing anxiety among disaster victims and delaying recovery efforts. Individuals working for the local media in Fukushima had the task of reporting the disaster while being victims of the disaster at the same time. Therefore, many individuals studied and deepened their knowledge about radiation and its effects, and were pained to see inaccurate media coverage of the disaster. Should they have been more forthright in opposing such false media coverage?

RESUMEN

Broad changes in normative health behavior are critical to overcoming many of the contemporary challenges to public health. Reduction in tobacco use during the last third of the 20th century-one of the greatest improvements in public health-illustrates such change. The culture change from accommodation to intolerance of smoking is irrefutable. The role of health communication in predisposing, enabling, and reinforcing the normative social changes that ensued, however, has been less well documented with the linear, cause-and-effect methods of controlled intervention research. We examine the role of mass communication in the cultural transformation that reduced tobacco use, concluding that its influence on reduction in tobacco use follows a pathway as much through secondary transmissions within groups of people as through direct influence on individuals.
