An Examination of Factors Contributing to the Acceptance of Online Health Misinformation

Misinformation and COVID-19 vaccine uptake hesitancy among frontline workers in Tanzania: Do demographic variables matter?

Although COVID-19 vaccination has been widely considered as an important remedy to confront COVID-19, people remain hesitant to take it. The objective of this study was to assess the moderation effects of demographic characteristics on the relationship between forms of misinformation and COVID-19 vaccine uptake hesitancy among frontline workers in Dar es Salaam and Dodoma, Tanzania. Using a sample of 200 respondents, it assessed the differences in ratings on misinformation regarding COVID-19 vaccine based on respondents' demographics. The study used a Five-point Likert scale questionnaire distributed through snowball sampling to frontline workers from Dar es Salaam and Dodoma regions. Data was analyzed using binary logistic regression. It was found that the forms of misinformation revealed were manipulated imposters, satire, fabricated contents and false contents with their connection, which they influenced COVID-19 hesitancy significantly. With exception of age, that significantly moderated hesitancy, this study uncovers that, sex and education level moderated insignificantly in predicting those who are misinformed; misinformed individuals are not any less educated or not based on one's sex, different than individuals who are informed. The study informs policy makers on devising appropriate strategies to promote COVID-19 vaccination uptake among the different contextual demographic variables. Promotion of information, media and health literacy to the general public should be considered to deter spreading of vaccine-related misinformation.

Evaluation of Oropharyngeal Cancer Information from Revolutionary Artificial Intelligence Chatbot

OBJECTIVE

With burgeoning popularity of artificial intelligence-based chatbots, oropharyngeal cancer patients now have access to a novel source of medical information. Because chatbot information is not reviewed by experts, we sought to evaluate an artificial intelligence-based chatbot's oropharyngeal cancer-related information for accuracy.

METHODS

Fifteen oropharyngeal cancer-related questions were developed and input into ChatGPT version 3.5. Four physician-graders independently assessed accuracy, comprehensiveness, and similarity to a physician response using 5-point Likert scales. Responses graded lower than three were then critiqued by physician-graders. Critiques were analyzed using inductive thematic analysis. Readability of responses was assessed using Flesch Reading Ease (FRE) and Flesch-Kincaid Reading Grade Level (FKRGL) scales.

RESULTS

Average accuracy, comprehensiveness, and similarity to a physician response scores were 3.88 (SD = 0.99), 3.80 (SD = 1.14), and 3.67 (SD = 1.08), respectively. Posttreatment-related questions were most accurate, comprehensive, and similar to a physician response, followed by treatment-related, then diagnosis-related questions. Posttreatment-related questions scored significantly higher than diagnosis-related questions in all three domains (p < 0.01). Two themes of the physician critiques were identified: suboptimal education value and potential to misinform patients. The mean FRE and FKRGL scores both indicated greater than an 11th grade readability level-higher than the 6th grade level recommended for patients.

CONCLUSION

ChatGPT responses may not educate patients to an appropriate degree, could outright misinform them, and read at a more difficult grade level than is recommended for patient material. As oropharyngeal cancer patients represent a vulnerable population facing complex, life-altering diagnoses, and treatments, they should be cautious when consuming chatbot-generated medical information.

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.

You must be myths-taken: Examining belief in falsehoods during the COVID-19 health crisis

The prevalence of health myths is increasing with the rise of Internet use. Left unaddressed, online falsehoods can lead to harmful behaviours. In times of crisis, such as the recent COVID-19 pandemic, the circulation of many myths is exacerbated, often to varying degrees among different cultures. Singapore is a multicultural hub in Asia with Western and Asian influences. Although several studies have examined health myths from a Western or Eastern perspective, little research has investigated online health falsehoods in a population that is culturally exposed to both. Furthermore, most studies examined myths cross-sectionally instead of capturing trends in myth prevalence over time, particularly during crisis situations. Given these literature gaps, we investigated popular myths surrounding the recent COVID-19 pandemic within the multicultural setting of Singapore, by examining its general population. We further examined changes in myth beliefs over the two-year period during the pandemic, and population demographic differences in myth beliefs. Using randomised sampling, two online surveys of nationally representative samples of adults (aged 21-70 years) residing in Singapore were conducted, the first between October 2020 and February 2021 (N = 949), and the second between March and April 2022 (N = 1084). Results showed that 12.7% to 57.5% of the population were unable to identify various myths, such as COVID-19 was manmade, and that three of these myths persisted significantly over time (increases ranging from 3.9% to 9.8%). However, belief in myths varied across population demographics, with ethnic minorities (Indians and Malays), females, young adults and those with lower education levels being more susceptible to myths than their counterparts (p < 0.05). Our findings suggest that current debunking efforts are insufficient to effectively counter misinformation beliefs during health crises. Instead, a post-COVID-19 landscape will require targeted approaches aimed at vulnerable population sub-groups, that also focus on the erroneous beliefs with long staying power.

Counteracting sexual and reproductive health misperceptions: Investigating the roles of stigma, misinformation exposure, and information overload

OBJECTIVE

Sexual and reproductive health (SRH) misperceptions constitute a critical precursor to undesired health outcomes for women. Drawing on the model of stigma management communication and exposure effects, we aimed to investigate the underlying processes of SRH misperceptions.

METHODS

A nationwide survey was conducted via quota sampling with Chinese women (N = 1000). Structural equation modeling with maximum likelihood estimation and 5000 bootstrapping resamples were used to test the hypotheses.

RESULTS

Stigma perceptions positively predicted information avoidance (β = 0.207, p < 0.001), which, in turn, was positively associated with misperceptions (β = 0.195, p < 0.001). Misinformation exposure significantly predicted misperceptions (β = 0.607, p < 0.001), and this relationship was mediated by information avoidance (β = 0.020, 95% CI [0.007, 0.040]). Moreover, information overload strengthened the relationship between misinformation exposure and information avoidance (β = 0.153, p < 0.001) as well as the relationship between misinformation exposure and misperceptions (β = 0.077, p = 0.006).

CONCLUSION

Stigma and misinformation exposure play prominent roles in the formation of SRH misperceptions. Information overload facilitates the misinformation-misperception transformation.

PRACTICE IMPLICATIONS

To counteract SRH misperceptions, health education should alleviate SRH stigma perceptions and strategically design messages to avoid information avoidance and overload.

Canadians' knowledge of cancer risk factors and belief in cancer myths

BACKGROUND

Many untrue statements about cancer prevention and risks are circulating. The objective of this study was to assess Canadians' awareness of known cancer risk factors and cancer myths (untruths or statements that are not completely true), and to explore how awareness may vary by sociodemographic and cognitive factors.

METHODS

Cancer myths were identified by conducting scans of published, grey literature, and social media. Intuitive-analytic thinking disposition scores included were actively open- and close-minded thinking, as well as preference for intuitive and effortful thinking. A survey was administered online to participants aged 18 years and older through Prolific. Results were summarized descriptively and analyzed using chi-square tests, as well as Spearman rank and Pearson correlations.

RESULTS

Responses from 734 Canadians were received. Participants were better at identifying known cancer risk factors (70% of known risks) compared to cancer myths (49%). Bivariate analyses showed differential awareness of known cancer risk factors (p < 0.05) by population density and income, cancer myths by province, and for both by ethnicity, age, and all thinking disposition scores. Active open-minded thinking and preference for effortful thinking were associated with greater discernment. Tobacco-related risk factors were well-identified (> 90% correctly identified), but recognition of other known risk factors was poor (as low as 23% for low vegetable and fruit intake). Mythical cancer risk factors with high support were consuming additives (61%), feeling stressed (52%), and consuming artificial sweeteners (49%). High uncertainty of causation was observed for glyphosate (66% neither agreed or disagreed). For factors that reduce cancer risk, reasonable awareness was observed for HPV vaccination (60%), but there was a high prevalence in cancer myths, particularly that consuming antioxidants (65%) and organic foods (45%) are protective, and some uncertainty whether drinking red wine (41%), consuming vitamins (32%), and smoking cannabis (30%) reduces cancer risk.

CONCLUSIONS

While Canadians were able to identify tobacco-related cancer risk factors, many myths were believed and numerous risk factors were not recognized. Cancer myths can be harmful in themselves and can detract the public's attention from and action on established risk factors.

Ivermectin prescription fill rates among U.S. Military members during the coronavirus disease 2019 (COVID-19) pandemic

This report describes ivermectin prescription fill rates among U.S. active component service members (ACSM) over time during the early phases of the COVID-19 pandemic. Information about the unsubstantiated benefits of ivermectin for coronavirus 2019 (COVID-19) prevention and treatment was widely available online early in the COVID-19 pandemic. Ivermectin prescription fill rates increased among ACSM during periods of Alpha and Delta coronavirus variant predominance, but not during the predominance of the Omicron variant. At the peak of the fill rate curve, in August 2021, rates were higher among men compared to women, older compared to younger age groups, senior officers compared to junior officers, senior enlisted compared to junior enlisted service members, and those with a bachelor's or advanced degree compared to those without a bachelor's degree. Ivermectin prescriptions were more likely to have been filled at a retail pharmacy than at a military hospital or clinic. During the COVID-19 pandemic fill rates for ivermectin prescriptions among ACSM increased, including those without a qualifying diagnosis. Rates peaked in August 2021 but subsequently declined. The decrease in ivermectin fill rates was coincident with vigorous efforts to correct previous misinformation and implement pre-authorization requirements for prescriptions. Research on the impact of unproven online claims about clinical and public health interventions has potential to curtail future unnecessary and potentially harmful treatments.

Trust in information sources as a moderator of the impact of COVID-19 anxiety and exposure to information on conspiracy thinking and misinformation beliefs: a multilevel study

This study investigates the intricate relationship between exposure to information sources, trust in these sources, conspiracy and misinformation beliefs, and COVID-19 anxiety among 509 Omani citizens aged 11 to 50, representing 11 governorates. Employing structural equation modeling, we not only examine these associations but also explore how trust and COVID-19 anxiety act as moderating variables in this context. Additionally, we delve into demographic factors such as age group, educational level, gender, and place of residence (governorate) to discern potential variations.Our findings reveal that trust in health experts is inversely related to belief in conspiracy theories, while trust in health experts negatively correlates with exposure to conspiracy and misinformation. Intriguingly, trust in health experts exhibits divergent effects across governorates: it diminishes conspiracy and misinformation beliefs in some regions but not in others. Exposure to personal contacts and digital media, on the other hand, is associated with heightened beliefs in misinformation and conspiracy theories, respectively, in select governorates. These distinctions may be attributed to proximity to Muscat, the capital city of Oman, where various media outlets and policy-making institutions are situated. Furthermore, lower educational attainment is linked to greater belief in conspiracy and misinformation. Females reported higher levels of conspiracy theory beliefs and COVID-19 anxiety while no significant differences were detected in misinformation beliefs.This study sheds light on the intricate dynamics of misinformation and conspiracy theories in the context of COVID-19 in Oman, highlighting the pivotal roles of trust and COVID-19 anxiety as moderating factors. These findings offer valuable insights into understanding and addressing the spread of misinformation and conspiracy theories during a public health crisis.

Unfavourable beliefs about oral health and safety of dental care during pregnancy: a systematic review

BACKGROUND

Oral conditions such as gingivitis and periodontitis are correlated with adverse pregnancy outcomes such as preeclampsia, preterm birth and low birth weight. Oral health-related unfavourable beliefs can have negative influences on oral health behaviours including hesitation in accessing preventative dental treatments and dental service utilization. The objective of this systematic review was to examine unfavourable beliefs that expectant or new mothers frequently hold about oral health and the safety of dental care during pregnancy.

METHODS

An electronic database search on PubMed, Scopus, CINAHL, and MEDLINE (Ovid) followed by forward and backward citation tracing of the included studies was conducted. All English primary studies regardless of the year of publication were independently screened by two reviewers to identify studies addressing unfavourable beliefs about oral health and dental care during pregnancy. The CLARITY tool was applied to assess the risk of bias in the included studies.

RESULTS

Out of a total of 5766 records, 39 quantitative and six qualitative studies met the inclusion criteria. The commonly held unfavourable beliefs were regarding the safety of dental services utilization and dental treatment procedures, the adverse impacts of pregnancy on oral health, and oral hygiene necessity during pregnancy. The most discussed unfavourable beliefs included "pregnant women lose their teeth because of pregnancy" (n = 18), "dental treatments are not safe and harm the fetus" (n = 17), and "the developing baby absorbs calcium from the mother's teeth" (n = 14).

CONCLUSIONS

Unfavourable beliefs about oral health and dental care utilization are common among pregnant women and new mothers. The literature suggests that a low level of oral health knowledge and seeking information from social networks can contribute to such beliefs. This has implications for health promotion.

Examining the Persuasive Effects of Health Communication in Short Videos: Systematic Review

BACKGROUND

The ubiquity of short videos has demonstrated vast potential for health communication. An expansion of research has examined the persuasive effect of health communication in short videos, yet a synthesis of the research is lacking.

OBJECTIVE

This paper aims to provide an overview of the literature by examining the persuasive effect of health communication in short videos, offering guidance for researchers and practitioners. In particular, it seeks to address 4 key research questions: What are the characteristics of short videos, samples, and research designs in short video-based health communication literature? What theories underpin the short video-based health communication literature? What are the persuasive effects of health communication in short videos? and What directions should future research in this area take?

METHODS

Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, an electronic search of 10 databases up to March 10, 2023, generated 4118 results. After the full-text screening, 18 articles met the eligibility criteria.

RESULTS

The current research lacks a uniform definition of short videos, demonstrates sample biases in location and education, and adopts limited methodologies. Most studies in this synthesis are theoretically grounded or use theoretical concepts, which are predominantly well examined in persuasion research. Moreover, relevant topics and suitable themes are effective in persuasive health communication outcomes, whereas the impact of diverse narrative techniques remains ambiguous.

CONCLUSIONS

We recommend that future research extends the definition of short videos beyond time constraints and explores non-Western and less-educated populations. In addition, researchers should consider diverse methods to provide a more comprehensive examination and investigate the impact of audience targeting and narrative techniques in short video health communication. Finally, investigating how the unique aspects of short videos interact with or challenge traditional persuasion theories is essential.

Deepfakes and scientific knowledge dissemination

Science misinformation on topics ranging from climate change to vaccines have significant public policy repercussions. Artificial intelligence-based methods of altering videos and photos (deepfakes) lower the barriers to the mass creation and dissemination of realistic, manipulated digital content. The risk of exposure to deepfakes among education stakeholders has increased as learners and educators rely on videos to obtain and share information. We field the first study to understand the vulnerabilities of education stakeholders to science deepfakes and the characteristics that moderate vulnerability. We ground our study in climate change and survey individuals from five populations spanning students, educators, and the adult public. Our sample is nationally representative of three populations. We found that 27-50% of individuals cannot distinguish authentic videos from deepfakes. All populations exhibit vulnerability to deepfakes which increases with age and trust in information sources but has a mixed relationship with political orientation. Adults and educators exhibit greater vulnerability compared to students, indicating that those providing education are especially susceptible. Vulnerability increases with exposure to potential deepfakes, suggesting that deepfakes become more pernicious without interventions. Our results suggest that focusing on the social context in which deepfakes reside is one promising strategy for combatting deepfakes.

Web-Based Health Information–Seeking Methods and Time Since Provider Engagement: Cross-sectional Study

Background

The use of web-based methods to seek health information is increasing in popularity. As web-based health information (WHI)–seeking affects health-related decision support and chronic symptom self-management, WHI-seeking from online sources may impact health care decisions and outcomes, including care-seeking decisions. Patients who are routinely connected to physicians are more likely to receive better and more consistent care. Little is known about whether WHI-seeking impacts the frequency at which patients engage with health care providers.

Objective

Our primary objective was to describe the associations between the use of web-based methods to seek information about one’s own health and the time since last engaging with a health care provider about one’s own health. Additionally, we aimed to assess participants’ trust in health care organizations to contextualize our findings.

Methods

We analyzed data from US adults participating in the nationally representative Tufts Equity in Health, Wealth, and Civic Engagement Survey (N=1034). Bivariate associations between demographic characteristics and health information–seeking methods were assessed with Pearson chi-squared tests. Bivariate associations of Medical Mistrust Index (MMI) scores with each health information–seeking method and time since provider engagement were assessed with F tests and adjusted Wald tests. We fit a multivariable logistic regression model to assess the association between WHI-seeking within the 12 months prior to survey (alone or in combination with provider-based methods versus provider only) and engagement with a provider more than 1 year prior to the time of survey, adjusting for age, race and ethnicity, sex, education, insurance coverage, and MMI.

Results

Age, race and ethnicity, educational attainment, health insurance source, MMI, and time since provider engagement were each significantly associated with the health information–seeking method in bivariate analyses. Compared to using only provider-based health information seeking methods, WHI-based methods alone or in combination with provider-based methods were associated with a 51% lower likelihood (odds ratio 0.49, 95% CI 0.27-0.87) of engaging with a provider within the previous year. Participants who used WHI-seeking methods alone and those who had not engaged with a health care provider within the previous year demonstrated a higher mean MMI score; however, MMI was not a significant predictor of time since engagement with a provider in the multivariable analysis.

Conclusions

Our findings from a nationally representative survey suggest that for those who use WHI-seeking methods (alone or in combination with provider-based information-seeking methods), there is a statistically significant lower likelihood of engaging with a provider in a year compared to those who only use provider-based methods. Future research should consider the intent of a person’s visit with a provider, trust in health care systems, methods of provider engagement, and specific web-based platforms for health information.

How Health-Related Misinformation Spreads Across the Internet: Evidence for the "Typhoon Eye" Effect

Online health-related misinformation has become a major problem in society and in-depth research is needed to understand its propagation patterns and underlying mechanisms. This study proposes a psychological typhoon eye effect to understand how health-related misinformation spreads during the pandemic using two national studies. In Study 1, we collected online search data from the United States and China to explore the relationship between the physical distance from the epicenter and the spread of health-related misinformation. Two common pieces of health-related misinformation were examined: "Microwaves kill coronavirus" in the United States and "Taking a hot bath can prevent against COVID-19" in China. Our results indicated a "typhoon eye effect" in the spread of two actual pieces of health-related misinformation using online data from the United States and China. In Study 2, we fabricated a piece of health-related misinformation, "Wash Clothes with Salt Water to Block Infection," and measured the spread behavior and perceived credibility of the misinformation. Again, we observed a typhoon eye effect on the spread behavior as well as the perceived credibility of health-related misinformation among people with limited education. In addition, based on the stimulus-organism-response theory, perceived credibility could serve as a mediator in the relationship between physical distance from the epicenter and the spread of health-related misinformation. Our results highlight the importance of psychological approaches to understanding the propagation patterns of health-related misinformation. The present findings provide a new perspective for development of prevention and control strategies to reduce the spread of health-related misinformation during pandemics.

Motivational Influences Affecting Middle-Aged and Elderly Users' Participation Intention in Health-Related Social Media

Social media provide users with multi-directional dialogue for creating and sharing health information that can effectively promote the self-management of health. In regard to the 'greying' trend in social media, most researchers have studied the health-related social media (HRSM) acceptance status and use behavior of middle-aged and elderly people, and have explored the role of HRSM in this group. However, the continuous participation of users is the key to the successful operation of HRSM, and is an essential prerequisite for the subsequent HRSM behavior habits of middle-aged and elderly people. Therefore, we aimed to explore what motivations drive the first use of HRSM among middle-aged and older adults, and the impact of their perception of HRSM, after personal use, on their intention to use it continually. In the study, we used the partial least squares structural equation model (PLS-SEM) to analyze data collected from online questionnaires. The results showed that a self-protection motivation and a social motivation promoted the initial participation of middle-aged and elderly individuals. In addition, these people experienced deeper levels of perceived usefulness and perceived entertainment after their initial participation. The results also revealed that these two perceptions could positively influence middle-aged and elderly individuals' intention to continue with their participation. Our findings should help service platforms to better understand the needs of middle-aged and elderly users. This would help researchers and practitioners to gain a more complete understanding of the motivation of middle-aged and elderly people for participating in HRSM, and the related impacts this may have.

Public Engagement with Biotechnology Inside and Outside the Classroom: Community-Focused Approaches

Biotechnology offers vast benefits to the environment, animals, and human health, and contributes to improving socioeconomic conditions for the public. However, biotechnology innovations continue to trigger public concern and opposition over their potential social, health, and ecological risks. There is an opportunity to increase knowledge and acceptance of biotechnology through engagement, education, and community participation. In this perspective, we highlight crucial factors that shape the public perception of biotechnology and present opportunities for scientists to effectively communicate their ideas while engaging with local and global communities. Initiatives that seek to involve communities in design, development, and adoption processes are crucial for the successful implementation of biotechnology-based solutions.

Narrative elaboration makes misinformation and corrective information regarding COVID-19 more believable

OBJECTIVE

People gather information about health topics from online channels oftentimes awash with misinformation. Investigating this problem during the COVID-19 pandemic is important, as the misinformation effect occurs when misleading details are embedded in narratives and questions. This pilot study investigated whether narrative elaboration increases believability in misinformation statements about COVID-19, and willingness to share these statements online.

RESULTS

Results from our online survey (n = 80) demonstrated that narrative elaboration increased believability in both misinformation and accurate statements, with a more pronounced effect on younger adults. Future research may investigate cognitive vulnerabilities imposed by elaborate narratives embedded in online health misinformation with increased attention on developing misinformation resilience among younger adults.

Consumer Attitudes towards Food Preservation Methods

The development and scope of using various food preservation methods depends on the level of consumers’ acceptance. Despite their advantages, in the case of negative attitudes, producers may limit their use if it determines the level of sales. The aim of this study was to evaluate the perception of seven different food processing methods and to identify influencing factors, such as education as well as living area and, at the same time, to consider whether consumers verify this type of information on the labels. Additionally, the study included the possibility of influencing consumer attitudes by using alternative names for preservation methods, on the example of microwave treatment. The results showed that conventional heat treatments were the most preferred preservation methods, whereas preservatives, irradiation, radio waves and microwaves were the least favored, suggesting that consumers dislike methods connected with “waves” to a similar extent as their dislike for preservatives. The control factors proved to significantly modify the evaluation of the methods. The analysis of alternative names for microwave treatment showed that “dielectric heating” was significantly better perceived. These research findings are important as the basis for understanding consumer attitudes. Implications for business and directions of future research are also indicated.

Dynamics of social corrections to peers sharing COVID-19 misinformation on WhatsApp in Brazil

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 726 Brazilian adults to identify the types of social correction behaviors (SCBs) and health and technological factors that shape the performance of these behaviors.

RESULTS

Brazil's WhatsApp users expressed medium to high levels of willingness to engage in SCBs. We discovered 3 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, the 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 Organization 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.

Predictors of COVID-19 Vaccine Acceptance and Hesitancy among Healthcare Workers in Southern California: Not Just "Anti" vs. "Pro" Vaccine

In this study, we evaluated the status of and attitudes toward COVID-19 vaccination of healthcare workers in two major hospital systems (academic and private) in Southern California. Responses were collected via an anonymous and voluntary survey from a total of 2491 participants, including nurses, physicians, other allied health professionals, and administrators. Among the 2491 participants that had been offered the vaccine at the time of the study, 2103 (84%) were vaccinated. The bulk of the participants were middle-aged college-educated White (73%), non-Hispanic women (77%), and nursing was the most represented medical occupation (35%). Political affiliation, education level, and income were shown to be significant factors associated with vaccination status. Our data suggest that the current allocation of healthcare workers into dichotomous groups such as "anti-vaccine vs. pro-vaccine" may be inadequate in accurately tailoring vaccine uptake interventions. We found that healthcare workers that have yet to receive the COVID-19 vaccine likely belong to one of four categories: the misinformed, the undecided, the uninformed, or the unconcerned. This diversity in vaccine hesitancy among healthcare workers highlights the importance of targeted intervention to increase vaccine confidence. Regardless of governmental vaccine mandates, addressing the root causes contributing to vaccine hesitancy continues to be of utmost importance.

Text Analysis Methods for Misinformation–Related Research on Finnish Language Twitter

The dissemination of disinformation and fabricated content on social media is growing. Yet little is known of what the functional Twitter data analysis methods are for languages (such as Finnish) that include word formation with endings and word stems together with derivation and compounding. Furthermore, there is a need to understand which themes linked with misinformation—and the concepts related to it—manifest in different countries and language areas in Twitter discourse. To address this issue, this study explores misinformation and its related concepts: disinformation, fake news, and propaganda in Finnish language tweets. We utilized (1) word cloud clustering, (2) topic modeling, and (3) word count analysis and clustering to detect and analyze misinformation-related concepts and themes connected to those concepts in Finnish language Twitter discussions. Our results are two-fold: (1) those concerning the functional data analysis methods and (2) those about the themes connected in discourse to the misinformation-related concepts. We noticed that each utilized method individually has critical limitations, especially all the automated analysis methods processing for the Finnish language, yet when combined they bring value to the analysis. Moreover, we discovered that politics, both internal and external, are prominent in the Twitter discussions in connection with misinformation and its related concepts of disinformation, fake news, and propaganda.

The Impact of COVID-19 Pandemic on Searching for Health-Related Information and Cyberchondria on the General Population in Italy

Objectives: The Internet has become one of the most common sources people use to search for health-related information, a behavior rapidly increased during the novel Coronavirus disease 2019 (COVID-19). The present study aimed to investigate behavioral patterns in the online health-related searches and Cyberchondria (CYB) during the COVID-19 pandemic time, in order to explore socio-demographic and psychopathological factors related to CYB. Methods: During the third wave of the COVID-19 pandemic in Italy, a cross-sectional online survey collected the main socio-demographic variables and habits related to Internet use of 572 participants. CYB was measured by the Cyberchondria Severity Scale-Short Version and different psychopathological factors were measured by specific questionnaires: the Coronavirus Anxiety Scale, the Hospital Anxiety and Depression Scale, the Short Health Anxiety Inventory, the Meta-Cognitions about Health Questionnaire, the Internet Addiction Test, the Maudsley Obsessional-Compulsive Questionnaire-Short Version, the Rosenberg's Self-Esteem Scale, and the WHO Quality of Life-BREF. Descriptives, non-parametric ANOVAs, and Spearman correlations were performed. Results: In the present sample, the Internet was the main source participants used to search for health-related information and nearly one-third increased this habit during the pandemic. Higher expression of CYB emerged in females, in younger participants, in students, and in those suffering from a physical/psychiatric illness. CYB showed a positive correlation with different phenomenology of anxiety (i.e., anxiety about COVID-19, health anxiety, general anxiety, metacognitive believes about anxiety) and with depression, obsessive-compulsive symptoms, and problematic usage of the Internet. Conversely, quality of life and self-esteem showed a negative correlation with CYB. Conclusion: During the COVID-19 pandemic, the use of the Internet for health-related information and CYB contribute to the psychological stress affecting individuals and society. Delineating subjects more vulnerable to CYB and associated psychopathological factors will help to elaborate operational indications for prevention and psychological support.
