"Using the extended parallel process model (PPM), this research examines whether and how humor functions to influence women’s breast self-examination (BSE) intention. We conducted a 2 (humor: present vs. absent) × 2 (threat: high vs. low) × 2 (efficacy: high vs. low) between-subjects experiment

in which we measured individual differences in BSE intention. The sample includes 480 Chinese women aged 20–50 years old. Results suggest that the 2-way interaction effect between threat and efficacy was significant, indicating that women who received messages containing high threat and high efficacy had the highest intention of BSE. In addition, the 3-way interaction effect between threat, efficacy, and humor was significant. The results indicate that if women perceive the threat of getting breast cancer as mild and believe that they are incapable of preventing it, messages with humor can significantly enhance their intention to engage in BSE when compared with messages without humor. Theoretical and practical implications of the findings are discussed." (Abstract)

igates the role of the perceived credibility of the fact checker as possible detriment to the effectiveness of fact-checking efforts by means of an online survey-embedded experiment. Results show that the perceived credibility of the fact checker and fact-checking messages is best explained by normative expectations of the roles of fact checkers and trust in traditional media. Some users perceive fact checkers as elite power structures in journalism or, in other words, as collaborative-facilitators for state propaganda. Further, low trust in media and politics predicts perceived credibility of disinformation better than political partisanship. The findings suggest that fact checkers should be more transparent and proactive in communicating their motives and identities. Further implications are discussed." (Abstract)

applied a randomised encouragement design to motivate our subjects to watch the series, addressing their self-selection issues concerning viewership. We randomly assigned a sample of 1,162 households into three arms: (T1) received weekly SMS reminders, (T2) received weekly SMSs and telephone calls, and (C) pure control. We followed up with 1,096 households, collected information on viewership and self-reported attitudes, and conducted a dictator game experiment to understand their revealed attitudes towards child marriage. We found considerable variations in viewership across the arms, suggesting associations with reminder intensity. Compared to the average control group viewership of about 0.15 episodes (SD = 0.82), T2 generated a difference of about 1.50–1.93 episodes (P < 0.01), depending on the respondent types. Following an instrumental variable approach, we found that exposure was not associated with both stated and revealed attitudes towards preventing child marriage. However, we found behavioural experiment was less prone to social desirability bias in assessing sensitive topics such as child marriage." (Publisher description)

radio stations receive the campaign and 800 women receive radios in campaign areas). Women receiving radios in status quo areas reduce contraception use by 5.2 percentage points. This negative effect is concentrated among those who wanted fewer children, consistent with mass media increasing social pressure to conform to the modal behavior in the media market. In contrast, receiving a radio in campaign areas increases contraception use by 5.8 percentage points. Comparing women in campaign vs noncampaign areas we find contraception use is 5.9 percentage points higher, births 10% lower, misperceptions about contraception lower, and reported welfare 0.27 standard deviations higher in campaign areas."

ICEF, disseminated on Facebook, influenced COVID-19 vaccine uptake in Ukraine, India, and Pakistan. In Ukraine, we deployed a stepped-wedge randomized controlled trial (RCT). Half of the 24 oblasts (provinces) received five weeks of the intervention, the other half ten weeks of the intervention. In India, an RCT with an augmented synthetic control was conducted in five states (Bihar, Chhattisgarh, Jharkhand, Madhya Pradesh, Rajasthan), whereby 40 out of 174 districts were randomized to receive six weeks of intervention. In Pakistan we deployed a pre-post design, whereby 25 city districts received six weeks of the intervention. Weekly COVID-19 vaccination data was sourced through government databases. Using Poisson regression models, the association between the intervention and vaccine uptake was estimated. In Ukraine we conducted a survey among Facebook users at three time points during the RCT, to ascertain vaccination intentions and trust in vaccines. The campaigns reached more than 110 million Facebook users and garnered 2.9 million clicks. In Ukraine, we found that the intervention did not affect oblast-level vaccination coverage (Relative Risk (RR): 0.93, 95% Confidence Interval (CI) 0.86-1.01). Similarly, in India and Pakistan we found no effect of our intervention (India: RR 0.85, 95% CI 0.70-1.04; Pakistan: RR 0.64, 95% CI 0.01-29.9). The survey among Facebook users in Ukraine showed that trust in vaccines and information sources was an important predictor of vaccination status and intention to get vaccinated. Our campaigns on Facebook had a wide reach, which did not translate in shifting behaviours. Timing and external events may have limited the effectiveness of our interventions." (Abstract)

aternal satisfaction, and overcome literacy barriers. Short, animated storytelling (SAS) is an innovative, emerging approach to mHealth messaging. Objective: We aimed to measure the effect of SAS videos on maternal knowledge and user satisfaction for mothers enrolled in antenatal care programs at 2 public health facilities in the Tshwane District of South Africa. Methods: We used a randomized controlled trial with a nested evaluation of user satisfaction. Participants were randomized 1:1 into Standard-of-Care (SOC) Control, and SAS Intervention groups. The intervention videos were delivered through WhatsApp, and 1 month later, participants responded to telephone surveys assessing their knowledge. The intervention group then participated in a nested evaluation of user satisfaction [...] Conclusions: While the SAS videos resulted in high user satisfaction, measured knowledge gains were small within a participant population that was already receiving perinatal health messages through antenatal clinics. The higher knowledge scores observed in older participants with higher education levels suggest that boosting maternal knowledge in younger mothers with lower education levels should continue to be a public health priority in South Africa. Given the high maternal satisfaction among the SAS video-users in this study, policy makers should consider integrating similar approaches into existing, broad-reaching perinatal health programs, such as MomConnect, to boost satisfaction and potentially enhance maternal engagement. While previous studies have shown the promise of animated video health education, most of this research has been conducted in high-income countries. More research in underresourced settings is urgently needed, especially as access to mobile technology increases in the Global South. Future studies should explore the effect of SAS videos on maternal knowledge in hard-to-reach populations with limited access to antenatal care, although real-world logistical challenges persist when implementing studies in underresourced South African populations."

We found that in 49% of the cases exposure to health misinformation damaged the psychological antecedents of behaviors such as knowledge, attitudes, or behavioral intentions. No RCTs evaluated the impact of exposure to misinformation on direct measures of health or pro-environmental behaviors (e.g., vaccination), and few studies explored the impact of misinformation on feelings, social norms, and trust. Most misinformation was based on logical fallacies, conspiracy theories, or fake experts. RCTs evaluating the impact of impossible expectations and cherry-picking are scarce. Most research focused on healthy adult US populations and used online samples. Future RCTs can build on our analysis and address the knowledge gaps we identified." (Abstract)

The findings illustrated that both fact-checking formats – factual and satirical – were equally effective in lowering issue agreement and perceived credibility in response to false information. Instead of a backfire effect, moreover, the regular factcheck was particularly effective among people who agreed with the fact-check information; for satirical fact-checking, the effect was found across-the-board. Both formats were ineffective in decreasing affective polarization; it rather increased polarization under specific conditions (satire; agreeing with the fact-check)." (Abstract)

rmation as a persistent societal threat can have an unintended spillover effect by decreasing the credibility of factually accurate news. Using an experimental design (N = 1305), we test whether credibility ratings of factually accurate news are subject to exposure to misinformation, corrective information, misinformation warnings, and news media literacy (NML) interventions relativizing the misinformation threat. Findings suggest that efforts like warning about the threat of misinformation can prime general distrust in authentic news, hinting toward a deception bias in the context of fear of misinformation being salient. Next, the successfulness of NML interventions is not straight forward if it comes to avoiding that the salience of misinformation distorts people’s creditabilityaccuracy. We conclude that the threats of the misinformation order may not just be remedied by fighting false information, but also by reestablishing trust in legitimate news." (Abstract)

Using a pre-registered experiment in the United States and India (N = 1008), we found that adding decontextualized visuals to disinformation on climate change did not amplify its effects on credibility or user engagement. Mimicking ordinary citizen cues has a stronger effect than using an alternative hyper-partisan media source to communicate disinformation under certain conditions. Low levels of media trust and preferences for information from the vox populi moderate the effects of citizen-initiated disinformation, suggesting that disenchanted citizens who oppose established information may be most vulnerable to disinformation attacks from social bots or trolls."

ositive association: perceptions of high prevalence of misinformation are correlated with high worries about COVID-19. However, the relationship is weaker in countries with higher levels of case-fatality ratios, and independent from the actual amount of misinformation per country. Study 2 replicates the relationship using experimental data. Furthermore, Study 2 demonstrates the underlying mechanism, that is, perceived prevalence of misinformation fosters the belief that COVID-19 is spiralling out of control, which in turn, increases worries. Our findings suggest that perceived prevalence of misinformation can have significant psychological effects, even though audience members reject the information as being false." (Abstract)

nline survey experiment with a diverse sample of 1105 participants in the U.S. In this experiment, we randomly exposed people to traditional warning messages about the threats of misinformation or relativising warning messages that placed misinformation’s threat in the context of the abundance of honest information. We additionally varied the specificity of the warning message (i.e. topic specific versus generic). We did not find direct overall effects on truth discernment but observed conditional effects on decreasing beliefs in misinformation and negative spillover effects on the truth rating of accurate information. We conclude that the effectiveness of media literacy interventions is far from straightforward, and document how preexisting media trust plays a key role in the effects of such interventions. Based on our findings, we suggest that the effectiveness of specific and general media literacy messages may be contingent upon tailoring the message to levels of existing (dis)trust." (Abstract)

through inauthentic or “troll” accounts that appear to be trustworthy members to the targeted polity, as in Russia's attempts to influence the 2016 US presidential election. We experimentally tested the efficacy of inoculation against inauthentic online actors, using the Spot the Troll Quiz, a free, online educational tool that teaches how to spot markers of inauthenticity. Inoculation works in this setting. Across an online US nationally representative sample (N = 2,847), which also oversampled older adults, we find that taking the Spot the Troll Quiz (vs. playing a simple game) significantly increases participants’ accuracy in identifying trolls among a set of Twitter accounts that are novel to participants. This inoculation also reduces participants’ self-efficacy in identifying inauthentic accounts and reduced the perceived reliability of fake news headlines, although it had no effect on affective polarization. And while accuracy in the novel troll-spotting task is negatively associated with age and Republican party identification, the Quiz is equally effective on older adults and Republicans as it was on younger adults and Democrats."

per are experimental and interventional studies that developed and tested public consumer-facing DHIs. We examined these DHIs to understand digital features, incorporation of theory, the role of healthcare professionals, end-user experience, and implementation issues. Results: The majority of studies (n=11) used social media in DHIs, but there was a lack of platform-agnostic generalizability. Only half of the studies (n=9) specified a theory, framework, or model to guide DHIs. Nine studies involve healthcare professionals as design or implementation contributors. Only one DHI was evaluated for user perceptions and acceptance. Discussion: The translation of advances in online social computing to interventions is sparse. The limited application of behavioral theory and cognitive models of reasoning has resulted in suboptimal targeting of psychosocial variables and individual factors that may drive resistance to misinformation. This affects large-scale implementation and community outreach efforts. DHIs optimized through community-engaged participatory methods that enable understanding of unique needs of vulnerable communities are urgently needed. Conclusions: We recommend community engagement and theory-guided engineering of equitable DHIs. It is important to consider the problem of misinformation and disinformation through a multilevel lens that illuminates personal, clinical, cultural, and social pathways to mitigate the negative consequences of misinformation and disinformation on human health and wellness."

By analyzing tweets (N=49,126) posted by 30 China’s media accounts before and after Twitter’s practice of labeling state-affiliated media, we reveal the corrective role that flagging plays in preventing people’s sharing of information from propaganda sources. The findings suggest that the corrective effect occurs immediately after these accounts are labeled as state-affiliated media and it leads to a long-term reduction in news sharing, particularly for political content. The results contribute to the understanding of how flagging efforts affect user engagement in real-world conversations and highlight that the effect of corrective measures takes place in a dynamic process."

show that partially false information is more credible and persuasive than completely false information, and also more difficult to correct. People with congruent prior attitudes are more likely to perceive misinformation as credible and agree with its positions than people with incongruent prior attitudes. We further show that although fact-checkers can lower the perceived credibility of misinformation on both runners and migrants, corrective messages do not affect attitudes toward migrants. As a key contribution, we show that different degrees of misinformation can have different impacts: more nuanced deviations from facticity may be more harmful as they are difficult to detect and correct while being more credible."
