Explaining Health Misinformation Belief through News, Social, and Alternative Health Media Use: The Moderating Roles of Need for Cognition and Faith in Intuition

Engaging and (the Illusion of) Learning? Examining the Relationship Between Different Social Media Activities and Reproductive Health Knowledge

Social media have become fundamental platforms for learning about health, including reproductive health knowledge. However, little is known about what specific user activity is conducive to learning about reproductive health and by what means. Drawing upon the cognitive mediation model, this study examines how different social media activities function in terms of elaboration and knowledge gain. Our hypothesized model was largely supported by a nationwide online survey with 1,000 Chinese women residing in both rural and urban areas. The results revealed the crucial role of information elaboration in bridging different social media activities with both subjective and factual reproductive health knowledge. Interestingly, public reposting of reproductive health information was found to be positively related to subjective knowledge but negatively related to factual knowledge, suggesting the emergence of an illusion of knowing among our participants. Multigroup SEM analyses revealed that the positive roles of scanning and private sharing in encouraging elaboration were more pronounced among users with lower levels of need for cognition. The findings are expected to contribute to a more nuanced understanding of health learning based on users' social media activities and intrinsic motivations for learning.

Mental health misinformation on social media: Review and future directions

Social media use for health information is extremely common in the United States. Unfortunately, this use may expose users to misinformation. The prevalence and harms of misinformation are well documented in many health domains (e.g., infectious diseases). However, research on mental health misinformation is limited. Our review suggests that mental health misinformation is common, although its prevalence varies across disorders and treatment types. Individual differences in susceptibility to misinformation have been documented for health misinformation generally but less so for mental health specifically. We discuss conceptual issues in defining mental health misinformation versus other classifications such as overgeneralizations from personal experience. Although there is clear evidence for false and actively misleading content, future research should also explore the role of negative healthcare experiences and health disparities on mental health misinformation on social media.

"I Know News Will Find Me": Examining the Relationship Between the "News-Finds-Me" Perception and COVID-19 Misperceptions

In the current media environment, some individuals have shifted from actively monitoring news toward passively waiting for the media to alert them about news to a certain extent, forming a "news-finds-me" (NFM) perception. Drawing on a cross-sectional survey (N = 906) of adults from the United States, this study investigates the relationship between the NFM perception and COVID-19 misperceptions. Findings demonstrated a positive association between NFM perception and misperceptions. Moreover, information avoidance mediated the relationship between NFM and misperception. Finally, need for cognition (NFC) was a significant moderator, such that among those with greater NFC, the indirect effect of NFM perception on misperceptions became weaker. Findings of this study can contribute to the literature of NFM perception in health contexts and provide useful guidelines for combating misinformation and misperceptions in the algorithm-generated information environment.

COVID-19 Vaccination Hesitancies: A Spanish-Language Focus Group Analysis in Texas

COVID-19 related health disparities are prevalent among higher risk populations like the Hispanic community. Vaccination is one readily available public health tool, yet vaccine uptake is lower among minority populations and hesitations and concerns are high. In the present study, interpersonal and media sources of information about COVID-19 were discussed in a series of six focus groups with Spanish-language dominant and bilingual English-Spanish respondents in a large metropolitan area in Texas. Participants reported using legacy media as a main source of information about COVID-19 vaccines and encountered conspiracy theories and misinformation on social media. Using the Health Belief Model as the theoretical lens, we found individuals' and family members' perceived susceptibility to COVID-19 played a part in participants wanting to find and get the vaccine. Provider recommendations may have served as cues to action. Ease of receiving the vaccines at church and pharmacies may have served to boost participants self-efficacy. Perceived barriers include vaccine specific reasons such as the fast pace of initial authorization, side effects, and long-term effects along with conspiracy theories. Prevailing information gaps regarding the COVID-19 vaccines and the resulting uncertainty are discussed. Understanding information sources and the trust Hispanic communities place in these sources is important in designing effective health messages.

The effect of visual attention process and thinking styles on environmental aesthetic preference: An eye-tracking study

People often form different aesthetic preferences for natural and built environments, which affects their behavioral intention; however, it remains unknown whether this difference in aesthetic preference is due to differences in thinking styles. However, whether tourists' aesthetic preferences differ when using different visual attention processes has not been studied further. This study used eye-tracking and self-reporting to investigate these questions. The results show that natural environment images are more favored visually because they can evoke in tourists larger pupil diameters and longer scan paths, but we found no significant difference in fixation duration and fixation counts. We also found that the scanning path of tourists who predominantly rely on intuitive thinking is modulated by the bottom-up attention process, while the scanning path of tourists who prefer rational thinking is modulated by the top-down attention process. In the bottom-up process, tourists who prefer rational thinking exhibit more positive aesthetic preferences and emotional arousal. In summary, the present study verified that aesthetic preference is more likely to be influenced by both thinking style and visual attention processing. The results of the present work provide preliminary evidence that the aesthetic preference of the environment is not only related to visual attention but also affected by the individual visual attention process and thinking style.

Recommending Breast Cancer Screening to My Mum: Examining the Interplay of Threat, Efficacy, and Virality on Recommendation Intention in the Chinese Context

The burgeoning eHealth campaigns and the emerging daughter-to-mother health communication necessitate a close examination of the intricate mechanism behind recommending preventive behaviors in online settings. The present study addresses existing gaps by investigating how message characteristics and platform-generated virality cues jointly influence younger females' intention to recommend breast cancer screening to their mothers. Drawing on the extended parallel process model (EPPM) as the theoretical basis, a 2 (threat: low vs. high) × 2 (efficacy: low vs. high) × 2 (virality: low vs. high) randomized between-subjects experiment (n = 269) was performed. Results revealed a three-way interaction effect between threat, efficacy, and virality on message involvement. Message involvement was positively associated with recommendation intention and mediated the three-way interaction effect on recommendation intention. This study demonstrates that a high threat can initiate message involvement but fail to trigger recommendation intention. In contrast, a low-threat, high-efficacy, high-virality combination would yield a salutary outcome. Besides, the indispensable role of message involvement in the underlying psychological mechanism behind recommending preventive behaviors was reaffirmed. Theoretical and practical implications are further discussed.

COVID-19 News Exposure and Vaccinations: A Moderated Mediation of Digital News Literacy Behavior and Vaccine Misperceptions

Being exposed to and believing in misinformation about COVID-19 vaccines is a challenge for vaccine acceptance. Yet, how countervailing factors such as news literacy could complicate "the information exposure-belief in vaccine misinformation-vaccination" path needs to be unpacked to understand the communication of scientific information about COVID-19. This study examines (1) the mediating role of belief in vaccine misinformation between COVID-19 information exposure and vaccination behavior and (2) the moderating role of news literacy behaviors. We examine these relationships by collecting data in two distinct societies: the United States and South Korea. We conducted online surveys in June and September 2021 respectively for each country (N = 1336 [the U.S.]; N = 550 [South Korea]). Our results showed a significant moderated mediation model, in which the association between digital media reliance and COVID-19 vaccination was mediated through vaccine misperceptions, and the relationship between digital media reliance and misinformed belief was further moderated by news literacy behavior. Unexpectedly, we found that individuals with stronger news literacy behavior were more susceptible to misinformation belief. This study contributes to the extant literature on the communication of COVID-19 science through probing into the mediating role of belief in vaccine-related misinformation and the moderating role of news literacy behavior in relation to COVID-19 information exposure and vaccination behaviors. It also reflects the concept of news literacy behavior and discusses how it could be further refined to exert its positive impact in correcting misinformation beliefs.

The effects of acute hydrogen peroxide exposure on respiratory cilia motility and viability

COVID-19 has seen the propagation of alternative remedies to treat respiratory disease, such as nebulization of hydrogen peroxide (H₂O₂). As H₂O₂ has known cytotoxicity, it was hypothesised that H₂O₂ inhalation would negatively impact respiratory cilia function. To test this hypothesis, mouse tracheal samples were incubated with different H₂O₂ concentrations (0.1-1%) then cilia motility, cilia generated flow, and cell death was assessed 0-120 min following H₂O₂ treatment. 0.1-0.2% H₂O₂ caused immediate depression of cilia motility and complete cessation of cilia generated flow. Higher H₂O₂ concentrations (≥0.5%) caused immediate complete cessation of cilia motility and cilia generated flow. Cilia motility and flow was restored 30 min after 0.1% H₂O₂ treatment. Cilia motility and flow remained depressed 120 min after 0.2-0.5% H₂O₂ treatment. No recovery was seen 120 min after treatment with ≥1% H₂O₂. Live/dead staining revealed that H₂O₂ treatment caused preferential cell death of ciliated respiratory epithelia over non-ciliated epithelia, with 1% H₂O₂ causing 35.3 ± 7.0% of the ciliated epithelia cells to die 120 min following initial treatment. This study shows that H₂O₂ treatment significantly impacts respiratory cilia motility and cilia generated flow, characterised by a significant impairment in cilia motility even at low concentrations, the complete cessation of cilia motility at higher doses, and a significant cytotoxic effect on ciliated respiratory epithelial cells by promoting cell death. While this data needs further study using in vivo models, it suggests that extreme care should be taken when considering treating respiratory diseases with nebulised H₂O₂.

COVID-19 Misinformation on Social Media and Public’s Health Behavior: Understanding the Moderating Role of Situational Motivation and Credibility Evaluations

The spread of misinformation on social networking conduit regarding COVID-19 pandemic poses deleterious consequences on public health. The author advance the body of knowledge on tackling misinformation to generate positive health behavior responses by proposing a conceptual framework based on the theory of persuasion and behavior change. Furthermore, as a belief antecedent, conspiracy theory is also used in this study. The author, using structural equation modeling technique, explored the three hundred seventy-three participants’ belief in conspiracy theory and religious misinformation and their influence on intention and behavior. Those direct relationships were tested by the joint moderating role of situational motivation and credibility evaluations. The study revealed that the situational motivation and credibility evaluation jointly and individually (in some cases) weaken the strong positive relationship between misinformation (conspiracy theory and religious misinformation) and health belief, health belief and intention, and intention and health behavior regarding COVID-19. The findings of this study offer guideline for policymakers to generate favorable health behavior regarding COVID-19 and any other epidemic or pandemic. Directions for researchers to any further extensions are also placed.

Effects of brief exposure to misinformation about e-cigarette harms on Twitter on knowledge and perceptions of e-cigarettes

Background

This study examined whether exposure to misinformation found on Twitter about e-cigarette harms leads to inaccurate knowledge and misperceptions of harms of e-cigarette use among cigarette smokers.

Methods

We conducted an online randomized controlled experiment in November 2019 among an online sample of 2400 adult US and UK cigarette smokers who did not currently use e-cigarettes. Participants viewed four tweets in one of four conditions: 1) e-cigarettes are as or more harmful than smoking, 2) e-cigarettes are completely harmless, 3) e-cigarette harms are uncertain and 4) control (physical activity). Outcomes were knowledge about e-cigarettes and harm perceptions of e-cigarette use for five diseases. We conducted multiple logistic and linear regressions to analyze the effect of experimental conditions on outcomes, controlling for baseline knowledge and perceived harms.

Findings

Participants in the ‘as or more harmful’ condition (vs. control group) had higher odds of accurate knowledge about e-cigarettes containing toxic chemicals ( p < 0.001), not containing only water vapor (p < 0.001) and containing formaldehyde ( p < 0.001). However, these participants had lower odds of accurate knowledge that e-cigarettes did not contain tar ( p < 0.001) and contained fewer toxins than cigarettes ( p < 0.001). Exposure to ‘as or more harmful’ tweets also increased harm perceptions for five diseases (all p < 0.001), with the greatest effect observed for lung cancer (β = 0.313, p < 0.001). This effect was greater among UK participants for all diseases.

Interpretation

Brief exposure to misinformation on Twitter reduced accurate knowledge of the presence of tar and the level of toxins compared with smoking and increased harm perceptions of e-cigarette use.
