We examined how age and exposure to different types of COVID-19 (mis)information affect misinformation beliefs, perceived credibility of the message and intention-to-share it on WhatsApp. Through two mixed-design online experiments in the UK and Brazil (total N = 1454) we first randomly exposed adult WhatsApp users to full misinformation, partial misinformation, or full truth about the therapeutic powers of garlic to cure COVID-19. We then exposed all participants to corrective information from the World Health Organisation debunking this claim. We found stronger misinformation beliefs among younger adults (18–54) in both the UK and Brazil and possible backfire effects of corrective information among older adults (55+) in the UK. Corrective information from the WHO was effective in enhancing perceived credibility and intention-to-share of accurate information across all groups in both countries. Our findings call for evidence-based infodemic interventions by health agencies, with greater engagement of younger adults in pandemic misinformation management efforts.
Objective Online COVID-19 misinformation is a serious concern in Brazil, home to the second largest WhatsApp user base and the second highest number of COVID-19 deaths. We examined the extent to which WhatsApp users might be willing to correct their peers who might share COVID-19 misinformation. Materials and Methods We conducted a cross-sectional online survey using Qualtrics among N = 726 Brazilian adults to identify the types of social correction behaviours (SCBs) and health and technological factors that shape the performance of these behaviours. Results Brazil’s WhatsApp users expressed medium to high levels of willingness to engage in SCBs. We discovered three modes of SCBs: correction to the group, correction to the sender only, and passive or no correction. WhatsApp users with lower levels of educational attainment and from younger age groups were less inclined to provide corrections. Lastly, perceived severity of COVID-19 and the ability to critically evaluate a message were positively associated with providing corrections to either the group or the sender. Discussion The demographic analyses point to the need to strengthen information literacy among population groups that are younger with lower levels of educational attainment. These efforts could facilitate individual-level contributions to the global fight against misinformation by the World Health Organisation in collaboration with member states, social media companies and civil society. Conclusion Our study suggests that Brazil’s WhatsApp users might be willing to actively respond with feedback when exposed to COVID-19 misinformation by their peers on small world networks like WhatsApp groups.
Healthy eating in the mass media and health promotion: social perceptions of community agents
Introduction: In recent years, the Internet has become an integral part of health surveillance, presenting and pointing to the growing use of social networks as an important tool for public health regarding health education on how to prevent infectious agents and also in monitoring emerging health threats, such as Aedes aegypti and arbovirus transmission. Considering that the Brazilian Ministery of Health accumulates more than 2 million followers on the Facebook page, it becomes pertinent to investigate the communication made by the Brazilian Ministery of Health through the posts on the page. Method: This is a descriptive and exploratory study that aimed to know the reality that involves the strategies of communication about arboviruses adopted by the Brazilian Ministery of Health in social networks, subject little studied from the point of view of collective health. The sample consisted of posts posted on the official Brazilian Ministery of Health Facebook profile in December 2015, 2016 and 2017, related to mosquito and arboviruses. After extracting the data into its own database, each of these posts was classified and categorized according to their themes and discourse. Results: A. aegypti has great role and importance among Brazilian Ministery of Health page publications. With common characteristics to the campaigns of Brazilian Ministery of Health, the posts presented the mosquito as villain and public enemy and used widely the war language and accountability of the population. Against the perspective of health-promoting communication, expressions denoting struggle and war are constantly used to try to conquer social mobilization. Conclusion: It is concluded that social networks are a space for health communication and it is essential that the federal manager of the SUS maintains health promoting communication strategies and not only the accountability of the population.
