Irrational beliefs differentially predict adherence to guidelines and pseudoscientific practices during the COVID-19 pandemic

The Relationship Between News Coverage of COVID-19 Misinformation and Online Search Behavior

The spread of health misinformation poses a threat to public health as it can influence individuals' health beliefs and, potentially, behaviors, and their support for public health policies. The mainstream news media have the potential to inadvertently increase the salience of misinformation through their reporting. This study explores the agenda-setting effects of mainstream news media coverage on public salience of public health misinformation during the COVID-19 pandemic. We analyzed the association between news media coverage and public salience - as measured by Google Trends relative search volume - of three different pieces of COVID-19 misinformation: (1) hydroxychloroquine is a safe and effective treatment for COVID-19; (2) the COVID-19 vaccines cause infertility; and (3) ivermectin is a safe and effective treatment for COVID-19. We plotted news coverage of each piece of misinformation against Google Trends relative search volume over time. Autoregressive integrated moving average (ARIMA) models were used to account for autocorrelation and analyze the relationship between the two time series. News media coverage volume was a significant predictor of same-day relative search volume for hydroxychloroquine and ivermectin. The relationship between news media coverage and searches for COVID-19 vaccines and infertility was not significant. These findings indicate mainstream news media coverage may contribute to the public salience of misinformation. Mainstream media outlets should contextualize their reporting on misinformation with verification from scientific consensus.

Lessons from a longitudinal community-based investigation of adherence to guidelines and intent to vaccinate during the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic is a major public health challenge. The US Centers for Disease Control published guidelines early in the pandemic emphasizing practicing good hygiene and staying at home, which were later modified.

PURPOSE

Using a community sample of 2152 participants in the state of Florida who responded to a series of online surveys, we tested a prediction model of adherence to guidelines and intent to vaccinate during the COVID-19 pandemic.

METHODS

Participants were assessed in May 2020, June 2020, and January 2021. Predictors included sociodemographic and psychological variables.

RESULTS

A slight decrease in adherence was reported over time. In multivariate models, older age, female sex, having health insurance, greater knowledge about COVID-19, more worry, less loneliness, and greater confidence and trust in COVID-19 information were all significantly and consistently associated with greater adherence to guidelines. Significant predictors of intent to vaccinate were male sex, greater knowledge, higher socioeconomic status, identifying as White, and greater guideline adherence (p's < 0.05).

CONCLUSIONS

Our findings highlight a number of significant predictors, including knowledge, loneliness, and confidence/trust. Critically these variables are modifiable and could therefore serve as targets in public health interventions to improve adherence to pandemic guidelines in the general population, as well as certain demographic characteristics that may influence intent to vaccinate. COVID-19 knowledge appears to play a central role in both adherence to guidelines and intent to vaccinate suggesting that having accurate information is critical for appropriate behavior.

A Comprehensive Analysis of COVID-19 Misinformation, Public Health Impacts, and Communication Strategies: Scoping Review

BACKGROUND

The COVID-19 pandemic was marked by an infodemic, characterized by the rapid spread of both accurate and false information, which significantly affected public health. This infodemic led to confusion, mistrust in health authorities, noncompliance with health guidelines, and engagement in risky health behaviors. Understanding the dynamics of misinformation during the pandemic is crucial for developing effective public health communication strategies.

OBJECTIVE

This comprehensive analysis aimed to examine the complexities of COVID-19 misinformation. Specifically, it sought to identify the sources and themes of misinformation, the target audiences most affected, and the effectiveness of various public health communication strategies in mitigating misinformation.

METHODS

This scoping review used the MEDLINE (PubMed), Embase, and Scopus databases to identify relevant studies. An established, methodical framework for scoping reviews was used to review literature published between December 2019 and September 2023. The inclusion criteria focused on peer-reviewed studies published in English that address COVID-19 misinformation and its sources, themes, and target audiences, as well as the effectiveness of public health communication strategies.

RESULTS

The scoping review identified that misinformation significantly impacted mental health, vaccine hesitancy, and health care decision-making. Social media and traditional media were major conduits for spreading misinformation. Key misinformation themes included the origins of the virus, ineffective treatments, and misunderstandings about public health measures. Misinformation sources ranged from social media platforms to traditional media outlets and informal networks. The impact of misinformation was found to vary across different regions and demographic groups, with vulnerable populations being disproportionately affected. Effective strategies to counter misinformation included enhancing health literacy; using digital technology; promoting clear, authoritative communication; and implementing fact-checking mechanisms. In addition, community engagement and targeted health campaigns played a crucial role in addressing misinformation.

CONCLUSIONS

The review emphasizes the critical need for accurate and consistent messaging to combat misinformation. Cooperative efforts among policy makers, health professionals, and communication experts are essential for developing effective interventions. Addressing the infodemic is vital for building a well-informed, health-literate society capable of handling misinformation in future global health crises. The study provides valuable insights into the dynamics of misinformation and highlights the importance of robust public health communication strategies. These findings can guide future efforts to mitigate the impact of misinformation during health emergencies.

Have we found a solution for health misinformation? A ten-year systematic review of health misinformation literature 2013-2022

BACKGROUND

Health misinformation (HM) has emerged as a prominent social issue in recent years, driven by declining public trust, popularisation of digital media platforms and escalating public health crisis. Since the Covid-19 pandemic, HM has raised critical concerns due to its significant impacts on both individuals and society as a whole. A comprehensive understanding of HM and HM-related studies would be instrumental in identifying possible solutions to address HM and the associated challenges.

METHODS

Following the PRISMA procedure, 11,739 papers published from January 2013 to December 2022 were retrieved from five electronic databases, and 813 papers matching the inclusion criteria were retained for further analysis. This article critically reviewed HM-related studies, detailing the factors facilitating HM creation and dissemination, negative impacts of HM, solutions to HM, and research methods employed in those studies.

RESULTS

A growing number of studies have focused on HM since 2013. Results of this study highlight that trust plays a significant while latent role in the circuits of HM, facilitating the creation and dissemination of HM, exacerbating the negative impacts of HM and amplifying the difficulty in addressing HM.

CONCLUSION

For health authorities and governmental institutions, it is essential to systematically build public trust in order to reduce the probability of individuals acceptation of HM and to improve the effectiveness of misinformation correction. Future studies should pay more attention to the role of trust in how to address HM.

Associations between vaccination and protective behaviors against COVID-19: transfer and redundancy effects as potential psychological mechanisms

This study aimed to investigate mechanisms explaining associations between vaccination and protective health behaviors during the COVID-19 pandemic. The study used a secondary analysis of data from a longitudinal online study at four time points between April 2020 and March 2021. Two hundred and forty participants responded to questionnaires assessing adherence to multiple COVID-19 protection behaviors, COVID-19 vaccination, behavioral specific outcome expectancies and general healthy lifestyle. Statistical analyses included z statistic for differences between correlations and moderation analysis by the SPSS PROCESS macro. The correlation between initial adherence to protective behaviors prior to availability of vaccination and actual vaccination was positive, but when vaccination was available, the concurrent correlation between these behaviors was null. Healthy lifestyle and outcome expectancies moderated the association between vaccination and adherence to protection behaviors. These results were explained by a 'redundancy effect', conceptualized as beliefs that engagement in specific health behaviors justifies evading other health behaviors. The 'redundancy effect' cancelled the initial positive correlation between vaccination and protective health behaviors, produced by a 'transfer effect', based on similarities between the perceived purposes of those behaviors. Theoretical and practical implications of the findings were discussed.

Conspire to one's own detriment: Strengthening HPV Program Support Through Debunking Epistemically Suspect Beliefs

The study experimentally tested an intervention that debunks epistemically suspect beliefs about vaccines. After answering questions about pre-existing epistemically suspect beliefs (irrational health beliefs and conspiracy mentality), 565 participants were randomly assigned into one of three conditions and exposed either to neutral information about domestic animals, salient epistemically suspect content about vaccination or an intervention that debunks epistemically suspect beliefs about vaccination. Afterwards, the participants answered questions about vaccination-related conspiracy narratives (manipulation check), vaccination attitudes, intentions to vaccinate against HPV, support for an HPV vaccination programme and intentions to seek health guidance. Although the intervention demonstrated the potential to inhibit the endorsement of conspiracy narratives, we found no differences in the other outcome variables. Nevertheless, across the conditions, pre-existing epistemically suspect beliefs were associated with less favourable attitudes towards vaccination, lower intentions to vaccinate against HPV, less support for the vaccination programme and lower intentions to seek health guidance. The results indicate that debunking may be futile in curbing long-term negative impacts associated with epistemically suspect beliefs, and they contribute to the debate about assessing the effectiveness of interventions related to highly controversial topics such as vaccination. The study enhances understanding of persistent adverse impacts that epistemically suspect beliefs may have on public health outcomes.

Students' mental health during the pandemic: results of the observational cross-sectional COVID-19 MEntal health inTernational for university Students (COMET-S) study

Introduction

The aim of the study was to search rates of depression and mental health in university students, during the COVID-19 pandemic.

Materials and methods

This is an observational cross-sectional study. A protocol gathering sociodemographic variables as well as depression, anxiety and suicidality and conspiracism was assembled, and data were collected anonymously and online from April 2020 through March 2021. The sample included 12,488 subjects from 11 countries, of whom 9,026 were females (72.2%; aged 21.11 ± 2.53), 3,329 males (26.65%; aged 21.61 ± 2.81) and 133 "non-binary gender" (1.06%; aged 21.02 ± 2.98). The analysis included chi-square tests, correlation analysis, ANCOVA, multiple forward stepwise linear regression analysis and Relative Risk ratios.

Results

Dysphoria was present in 15.66% and probable depression in 25.81% of the total study sample. More than half reported increase in anxiety and depression and 6.34% in suicidality, while lifestyle changes were significant. The model developed explained 18.4% of the development of depression. Believing in conspiracy theories manifested a complex effect. Close to 25% was believing that the vaccines include a chip and almost 40% suggested that facemask wearing could be a method of socio-political control. Conspiracism was related to current depression but not to history of mental disorders.

Discussion

The current study reports that students are at high risk for depression during the COVID-19 pandemic and identified specific risk factors. It also suggested a role of believing in conspiracy theories. Further research is important, as it is targeted intervention in students' groups that are vulnerable both concerning mental health and conspiracism.

Navigating the infodemic: A qualitative study of university students' information strategies during the COVID-19 pandemic

Objectives

We aimed to study the strategies which university students developed for vetting information during the COVID-19 pandemic and associated infodemic.

Methods

We conducted semi-structured interviews with 34 students, using a piloted topic guide which explored several areas of pandemic experiences, including students' use of media. Transcripts were analysed inductively following the thematic approach. Higher order themes were finalised following a coding exercise undertaken by two of the authors.

Results

Participants were acutely aware of misinformation during the pandemic. They rated legacy news media (print and broadcast media with pre-Internet origins) higher than social media for reliable information about the pandemic. However, strikingly, not all legacy media were automatically trusted and not all social media were uniformly distrusted. Participants identified a set of mechanisms for establishing whether a piece of information was truthful and accurate. These mechanisms had four main focal points: (1) the source, (2) the message, (3) individual media literacy and (4) the trustworthiness of others. Despite possessing a critical awareness of misinformation, participants avoided posting anything in relation to the pandemic for fear of becoming the target of online abuse.

Conclusions

In addition to underscoring the role of media literacy, our research foregrounds the need to attend to the importance of fostering media confidence. We define media confidence as the ability of digital media users to challenge and interrogate questionable or inaccurate information safe in the knowledge that there are adequate regulatory mechanisms in place to curb abuse, trolling and intimidation.

Psychological Factors of Vaccination Intent among Healthcare Providers, Parents, and Laypeople

The interrelatedness of social-structural aspects and psychological features with vaccination intention provides the context to explore personal psychological features related to vaccination. Specifically, we focused on general decision making and vaccine-related dispositions, and their contribution to the intention to vaccinate, within post-pandemic circumstances, after the imposed possibility of choosing a vaccine brand. Our study aimed to map the function (promotive, protective, risk, vulnerability) of a set of personal psychological aspects in the intention to vaccinate among people holding different social roles regarding the vaccination. We surveyed three samples of people: healthcare providers (HPs), parents, and laypeople, within the post-pandemic context. Negative vaccine attitudes lower intention to vaccinate in all regression models (all βs ranging from -0.128 to -0.983, all ps < 0.01). The main results indicate that, regardless of the sample/social role, there is a shared attitudinal core for positive vaccination intention. This core consists of [high] trust in large corporations, government, and healthcare systems, as well as perceived consensus on vaccine safety/efficacy and experience of freedom (protective factors), and [low] vaccination conspiracy beliefs, trust in social media, and choice overload (risk and vulnerability factors, respectively). There are no common promotive factors of intention to vaccinate: for parents, perceived consensus on vaccines, and trust in corporations and the healthcare system, play such roles; for HPs, the experience of freedom is obtained as a unique promotive factor. In contrast, for laypeople, no unique promotive factors were found. Our findings provide insights into the function of psychological factors of vaccination intention across different social roles, particularly healthcare providers, parents, and laypeople, and emphasize the need for tailored immunization interventions in the post-pandemic landscape.

Prevalence of questionable health behaviours in Serbia and their psychological roots: protocol for a nationally representative survey

INTRODUCTION

We will launch a national survey in Serbia to document the prevalence of two types of questionable health behaviours: (1) intentional non-adherence to medical recommendations and (2) use of traditional, complementary and alternative medicine practices, as well as the relation between the two. We will also investigate their psychological roots, including (a) 'distal' predictors such as HEXACO personality traits (plus Disintegration) and thinking dispositions (rational/experiential thinking and cognitive reflexivity), and (b) 'proximal' predictors under the umbrella 'irrational mindset' (set of unfounded beliefs consisting of conspiratorial thinking, superstition, magical health beliefs as well as selected cognitive biases), which have more content-wise overlap with the health behaviours.

METHODS AND ANALYSIS

In this cross-sectional study, a research agency will collect data from a nationally representative sample (n=1043; age 18-75 years; estimated start/end-June/November 2021) recruited online (approximately, 70% of the sample, aged 18-54; 11 years) and face-to-face (approximately, 30% of the sample, aged 55-75 years). Participants will complete a battery of tests assessing questionable health behaviours, basic personality traits, thinking dispositions, irrational mindset, sociopolitical beliefs, sociodemographic and health-related variables. Prevalence rates will be calculated using descriptive statistics. To explore the relation between (psychological) predictors and questionable health behaviours, we will use hierarchical regression and partial mediation models (path analysis or full SEM models).

ETHICS AND DISSEMINATION

Ethical Committees of the Faculty of Philosophy in Belgrade (#935/1), Faculty of Special Education and Rehabilitation (#139/1) and Faculty of Media and Communications (#228) approved the protocol. Only participants who provide informed consent will participate in the study. A research report based on the study results will be submitted to peer-reviewed journals and results will be made available to stakeholders through reports on the project website https://reasonforhealth.f.bg.ac.rs/en/ and disseminated via social media.

The relationship between maladaptive health beliefs, pandemic-related stress, and health anxiety during the COVID-19 pandemic

BACKGROUND

Research has demonstrated that people experience specific distress and anxiety regarding COVID-19. This distress may consist of interconnected symptom categories corresponding to a COVID stress syndrome. Susceptibility to COVID stress syndrome may be related to one's maladaptive health beliefs; however, no research has investigated the association between maladaptive health beliefs and COVID stress. The present study explored the impact of health beliefs on COVID stress, health anxiety, and associated psychological constructs.

PARTICIPANTS AND PROCEDURE

This cross-sectional survey study included 221 adults (M age = 20.59, SD = 2.28). Participants completed an online survey including demographic questionnaires and self-report measures of health beliefs, COVID stress, health anxiety, and related psychological constructs.

RESULTS

Health anxiety, anxiety sensitivity, state/trait anxiety, intolerance of uncertainty, and depression accounted for significant variance in COVID stress (F(6, 214) = 11.18, R2 = .24, p < .001). Health beliefs (i.e., perceived likelihood of illness, medical service inadequacy, and difficulty coping) were associated with greater COVID stress, although health beliefs were not found to mediate the relationship between health anxiety and COVID stress.

CONCLUSIONS

Health beliefs were associated with greater COVID stress, although health beliefs did not mediate the relationship between health anxiety and COVID stress. The relationship between health anxiety and COVID stress may be better explained by other COVID-related cognitions (e.g., vaccine efficacy, dangerousness of COVID-19). The findings highlight the importance of peoples' health beliefs during the pandemic. Given anxiety's influence on peoples' behavioural responses to the pandemic, further research should identify COVID-specific cognitions for prevention of COVID stress and health anxiety.

Conspiracy Theories, Trust in Science, and Knowledge during the Third Wave of the COVID-19 Pandemic in Cyprus

Conspiracy theories flourish during periods of crisis. One way to counteract the believability of conspiracy theories is trust in science and knowledge about the "perceived threat", such as the SARS-CoV-2 virus. A total of 363 adults from Cyprus were recruited via convenience and snowball sampling methods. The data were collected via an internet-based questionnaire that examined participants' belief in 17 conspiracy theory statements, trust in science and scientists, knowledge about the symptoms and the spread of the SARS-CoV-2 virus, phobic anxiety, hostility, somatization, and personality traits based on the Big Five. The results suggest (a) the overall belief in conspiracy theories in Cyprus is low, even though a notable percentage holds a neutral stance towards these theories; (b) trust in science and knowledge about the symptoms and the spread of the SARS-CoV-2 virus is negatively related to conspiracy theories, indicating the importance of trusting science and having knowledge as a means to counteract conspiracy theories; (c) young adults, those residing in rural areas, and those with a low education level are more likely to believe in conspiracy theories; (d) there are no significant associations between conspiracy theories and the psychological dimensions of phobic anxiety, hostility, and somatization; (e) there is difficulty in identifying specific traits related to conspiracy ideation. Public health officials could benefit from the findings when communicating information during periods of crisis.

Validating a German Version of the Conspiracy Mentality Scale (CMS)

Increased scientific interest in conspiracy beliefs raises the need for validated individual difference measures in the general tendency to believe in conspiracy theories, otherwise referred to as conspiracy mentality. In this article, we present a German language version of the Conspiracy Mentality Scale (CMS). A representative sample of German-speaking Swiss residents (N = 468) filled in the scale, along with measures of trust in several sources of information, need for social validation, compliance with Covid-19 preventive measures, perceived severity of the pandemic, loneliness, functional literacy and interpersonal conflict. Confirmatory factor analysis supported the two-dimensional structure of the original scale. Positive correlations between conspiracy theory ideation and trust in friends and the need for social validation on the one hand, and negative correlations with trust in scientific publications and scientific experts, perceived severity of the pandemic and functional literacy on the other hand supported construct validity. We conclude that our German language version of the scale is a valid measure of conspiracy theory ideation and skepticism.

Results of the COVID-19 mental health international for the health professionals (COMET-HP) study: depression, suicidal tendencies and conspiracism

INTRODUCTION

The current study aimed to investigate the rates of anxiety, clinical depression, and suicidality and their changes in health professionals during the COVID-19 outbreak.

MATERIALS AND METHODS

The data came from the larger COMET-G study. The study sample includes 12,792 health professionals from 40 countries (62.40% women aged 39.76 ± 11.70; 36.81% men aged 35.91 ± 11.00 and 0.78% non-binary gender aged 35.15 ± 13.03). Distress and clinical depression were identified with the use of a previously developed cut-off and algorithm, respectively.

STATISTICAL ANALYSIS

Descriptive statistics were calculated. Chi-square tests, multiple forward stepwise linear regression analyses, and Factorial Analysis of Variance (ANOVA) tested relations among variables.

RESULTS

Clinical depression was detected in 13.16% with male doctors and 'non-binary genders' having the lowest rates (7.89 and 5.88% respectively) and 'non-binary gender' nurses and administrative staff had the highest (37.50%); distress was present in 15.19%. A significant percentage reported a deterioration in mental state, family dynamics, and everyday lifestyle. Persons with a history of mental disorders had higher rates of current depression (24.64% vs. 9.62%; p < 0.0001). Suicidal tendencies were at least doubled in terms of RASS scores. Approximately one-third of participants were accepting (at least to a moderate degree) a non-bizarre conspiracy. The highest Relative Risk (RR) to develop clinical depression was associated with a history of Bipolar disorder (RR = 4.23).

CONCLUSIONS

The current study reported findings in health care professionals similar in magnitude and quality to those reported earlier in the general population although rates of clinical depression, suicidal tendencies, and adherence to conspiracy theories were much lower. However, the general model of factors interplay seems to be the same and this could be of practical utility since many of these factors are modifiable.

Tracking variations in daily questionable health behaviors and their psychological roots: a preregistered experience sampling study

People resort to various questionable health practices to preserve or regain health - they intentionally do not adhere to medical recommendations (e.g. self-medicate or modify the prescribed therapies; iNAR), or use traditional/complementary/alternative (TCAM) medicine. As retrospective reports overestimate adherence and suffer from recall and desirability bias, we tracked the variations in daily questionable health behaviors and compared them to their retrospectively reported lifetime use. We also preregistered and explored their relations to a wide set of psychological predictors - distal (personality traits and basic thinking dispositions) and proximal (different unfounded beliefs and biases grouped under the term irrational mindset). A community sample (N = 224) tracked daily engagement in iNAR and TCAM use for 14 days, resulting in 3136 data points. We observed a high rate of questionable health practices over the 14 days; daily engagement rates roughly corresponded to lifetime ones. Both iNAR and TCAM were weakly, but robustly positively related. Independent of the assessment method, an irrational mindset was the most important predictor of TCAM use. For iNAR, however, psychological predictors emerged as relevant only when assessed retrospectively. Our study offers insight into questionable health behaviors from both a within and between-person perspective and highlights the importance of their psychological roots.

How level of understanding and type of used sources relate to adherence to COVID-19 public health measures in Canada

Previous studies have highlighted the importance of promoting health literacy and minimizing misinformation to encourage higher adherence to key public health measures during the COVID-19 pandemic. This study explores how one's self-reported understanding of information and types of sources used to get information regarding COVID-19 can hinder adherence to public health measures implemented by the Canadian government. Data was collected following a longitudinal design of 11 time points for April 2020 to April 2021. The sub-sample used for this study included 2659 Canadians who completed the survey for at least four time points. Using Latent Class Growth Analysis, we modelled typical trajectories of adherence to three key public health measures: staying home, social distancing and mask wearing. Overall, a lower level of understanding was associated with lower adherence trajectories to public health measures, and vice-versa. Adjusted odds ratio (AOR) showed that the higher the level of understanding, the higher were the chances of following a high adherence trajectory. The type of used sources also showed a significant statistical association with adherence trajectories for social distancing and staying home (AOR: between 1.1 and 3.4). These results are discussed considering future policy implications.

Temporal changes in mental response and prevention patterns, and their impact from uncertainty stress during the transition in China from the COVID-19 epidemic to sporadic infection

An epidemic of a highly lethal disease can overwhelm people emotionally and physically. Little is known about how public mental and preventive patterns changed during the transition from the COVID-19 epidemic to sporadic infection. This study examined changing trends of metal response and behavioral variables, and their impact from uncertainty stress in this process in China. A prospective longitudinal observation design was utilized. There were 7 waves of surveys from COVID-19 epidemic status to the sporadic infection period. Sixty-two participants completed all observation points and were included in the study. The Mann-Kendall Test was used to assess changing trends across the seven observation points. The nonparametric linear mixed effects model was used to examine the association between uncertainty stress and mental and behavioral responses. The mean uncertainty stress did not change significantly over the observation period (Z: -0.911, p > 0.05). This trend was also true for perceived risk, perceived severity, self-efficacy for prevention, and prevention behavior. There was a statistically significant downward trend in irrational beliefs about prevention (Z: -4.993, p < 0.01), sleep (Z: -2.499, p < 0.05), emotions (Z: -5.650, p < 0.01), and lifestyle (Z: -5.978, p < 0.01). The results showed that uncertainty stress was positively associated with irrational beliefs (β: 0.16298, p < 0.01), their sleep (β: 0.02070, p < 0.05), emotions (β: 0.03462, p < 0.01), and lifestyle (β: 0.02056, p < 0.05). High levels of uncertainty stress were negatively associated with self-efficacy for prevention and prevention behavior, β was -1.33210 (p < 0.01) and -0.82742 (p < 0.01). These results may have important policy and disease prevention in post-epidemic times.

Development of a novel instrument for assessing intentional non-adherence to official medical recommendations (iNAR-12): a sequential mixed-methods study in Serbia

OBJECTIVES

We aimed to (1) develop a novel instrument, suitable for the general population, capturing intentional non-adherence (iNAR), consisting of non-adherence to prescribed therapy, self-medication and avoidance of seeking medical treatment; (2) differentiate it from other forms of non-adherence, for example, smoking; and (3) relate iNAR to patient-related factors, such as sociodemographics, health status and endorsement of irrational beliefs (conspiratorial thinking and superstitions) and to healthcare-related beliefs and experiences ((mis)trust and negative experiences with the healthcare system, normalisation of patient passivity).

DESIGN

То generate iNAR items, we employed a focus group with medical doctors, supplemented it with a literature search and invited a public health expert to refine it further. We examined the internal structure and predictors of iNAR in an observational study.

SETTING

Data were collected online using snowball sampling and social networks.

PARTICIPANTS

After excluding those who failed one or more out of three attention checks, the final sample size was n=583 adult Serbian citizens, 74.4% female, mean age 39.01 years (SD=12.10).

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary, planned outcome is the iNAR Questionnaire, while smoking was used for comparison purposes.

RESULTS

Factor analysis yielded a one-factor solution, and the final 12-item iNAR Questionnaire had satisfactory internal reliability (alpha=0.72). Health condition and healthcare-related variables accounted for 14% of the variance of iNAR behaviours, whereas sociodemographics and irrational beliefs did not additionally contribute.

CONCLUSIONS

We constructed a brief yet comprehensive measure of iNAR behaviours and related them to health and sociodemographic variables and irrational beliefs. The findings suggest that public health interventions should attempt to improve patients' experiences with the system and build trust with their healthcare practitioners rather than aim at specific demographic groups or at correcting patients' unfounded beliefs.

Nationalism, conspiracy theories and vaccine mandates: Exploring the statism determinants for attitudes to COVID-19 control in China

Introduction

China's loosening its COVID-19 controls highlighted its insufficiency in vaccination protection. Mandatory vaccination might be necessary if the gap cannot be filled over a short time. However, few studies have explored how Chinese people view the COVID-19 vaccine mandates, let alone placing such views in the country's highly politicized context.

Material and methods

The current study utilizes data from a national survey adopting quota sampling to analyze the Chinese public's medical and non-medical considerations when judging compulsory COVID-19 vaccination (n = 1,523). The survey was conducted between 1 and 8 April 2021. All adults aged 18 years and older were eligible to take part. The survey included sociodemographic details, perceived susceptibility to infection, perceived vaccine benefit, attitudes to vaccination policies, nationalism, beliefs in various conspiracy theories and science literacy. Multiple regression analyses were done to examine factors associated with the attitude to COVID-19 vaccine mandates.

Results

The study reveals that personal risk and benefit perceptions did not dominate the Chinese public's attitude toward vaccination mandates. Instead, nationalism was relatively strongly associated with their willingness to accept mandatory vaccination. Contrary to studies in the West, various conspiracy beliefs and conspiratorial thinking were robustly related to the support for mandatory vacciniation. Science literacy didn't link to the attitude to vaccination mandates. It only had a weak moderating effect on the influence of conspiratorial thinking on attitudes to the vaccination policies.

Conclusions

The results indicated that Chinese people's attitude to the COVID-19 vaccination policy is highly politicized and influenced by conspiracy theories. Given the potentially massive impacts of the COVID-19 infection, we need to educate the Chinese public with more medically valuable and relevant information to help them make sound decisions regarding vaccination. Meanwhile, we can adopt nationalistic tones to improve the persuasion effect, but misinformation during the process must be overcome.

Psychosocial Predictors and Mediators Relating to the Preventive Behaviors of Hospital Workers During the COVID-19 Pandemic in Turkey

OBJECTIVE

The aim is to analyze the relation of psychosocial factors to COVID-19 contraction, vaccination, and preventive health behavior in and outside work.

METHODS

The questionnaire data from hospital-workers in Turkey is analyzed using independent-samples t-test, logistic regression, linear regression, and mediation analyses. We developed a questionnaire on mask-hygiene-distance measures and also used previously developed scales including the Big Five Personality Questionnaire, Young Schema Questionnaire Short Form 3, Schwartz's Basic Human Values Scale, Short Dark Triad.

RESULTS

The odds of being infected by COVID-19 increases by self-direction. The odds of being vaccinated increases by age and conformity, and decreases by emotional stability. Education predicts certain preventive behaviors at work negatively and outside work positively. Older age, being a woman, having chronic disease, the self-transcendence and conservation values, agreeableness, and conscientiousness predict more preventive behaviors. The self-enhancement and openness to change values, the Dark Triad, and early maladaptive schemas predict more risky behaviors.

CONCLUSIONS

Designing prohealth policies requires further elaboration on the relation of psychosocial factors to preventive behaviors.

I trust my immunity more than your vaccines: "Appeal to nature" bias strongly predicts questionable health behaviors in the COVID-19 pandemic

Health care policies often rely on public cooperation, especially during a health crisis. However, a crisis is also a period of uncertainty and proliferation of health-related advice: while some people adhere to the official recommendations, others tend to avoid them and resort to non-evidence based, pseudoscientific practices. People prone to the latter are often the ones endorsing a set of epistemically suspect beliefs, with two being particularly relevant: conspiratorial pandemic-related beliefs, and the appeal to nature bias regarding COVID-19 (i.e., trusting natural immunity to fight the pandemic). These in turn are rooted in trust in different epistemic authorities, seen as mutually exclusive: trust in science and trust in the "wisdom of the common man". Drawing from two nationally representative probability samples, we tested a model in which trust in science/wisdom of the common man predicted COVID-19 vaccination status (Study 1, N = 1001) or vaccination status alongside use of pseudoscientific health practices (Study 2, N = 1010), through COVID-19 conspiratorial beliefs and the appeal to nature bias regarding COVID-19. As expected, epistemically suspect beliefs were interrelated, related to vaccination status, and to both types of trust. Moreover, trust in science had both a direct and indirect effect on vaccination status through both types of epistemically suspect beliefs. Trust in the wisdom of the common man had only an indirect effect on vaccination status. Contrary to the way they are typically portrayed, the two types of trust were unrelated. These results were largely replicated in the second study, in which we added pseudoscientific practices as an outcome; trust in science and the wisdom of the common man contributed to their prediction only indirectly, through epistemically suspect beliefs. We offer recommendations on how to make use of different types of epistemic authorities and how to tackle unfounded beliefs in communication during a health crisis.

Policy Endorsement and Booster Shot: Exploring Politicized Determinants for Acceptance of a Third Dose of COVID-19 Vaccine in China

China's recent termination of strict COVID-19 control necessitates taking a booster vaccine shot as a precaution against the pandemic as quickly as possible. A large body of research has examined people's attitudes toward and intentions for the booster shot. However, most studies failed to explore how China's sociopolitical context has shaped their attitude regarding the booster jab take-up. The current study utilizes data from a national survey adopting quota sampling to analyze the Chinese public's medical and non-medical considerations to determine their intention for the third dose of the COVID-19 vaccine. The study found that thanks to China's initial successful lockdown policies, personal risk and benefit perceptions did not dominate their views regarding booster vaccination. Instead, respondents' gender, nationalism, endorsement of the zero-COVID policy, self-efficacy regarding vaccination, and perceived infection severity were the major factors underlying their booster shot intention. The situation highlights how the politicized context of China's COVID-19 control has impacted people's plans to practice preventive behaviors. It is necessary to offset the negative consequences. One strategy is to educate the Chinese public with more medically relevant information to help them make rational choices regarding vaccination and other protective measures. On the other hand, such education can utilize this nationalistic mental status to enhance the persuasion effect.

Contemporary trends in psychological research on conspiracy beliefs. A systematic review

Background

The number of psychological studies on conspiracy beliefs has been systematically growing for about a dozen years, but in recent years, the trend has intensified. We provided a review covering the psychological literature on conspiracy beliefs from 2018 to 2021. Halfway through this period, the COVID-19 pandemic broke out, accompanied by an explosion of movements based on conspiracy theories, intensifying researchers' interest in this issue.

Methods

Adhering to PRISMA guidelines, the review systematically searched for relevant journal articles published between 2018 and 2021. A search was done on Scopus and Web of Science (only peer-reviewed journals). A study was included if it contained primary empirical data, if specific or general conspiracy belief(s) were measured and if its correlation with at least one other psychological variable was reported. All the studies were grouped for the descriptive analysis according to the methodology used, the participants' characteristics, the continent of origin, the sample size, and the conspiracy beliefs measurement tools. Due to substantial methodological heterogeneity of the studies, narrative synthesis was performed. The five researchers were assigned specific roles at each stage of the analysis to ensure the highest quality of the research.

Results

Following the proposed methodology, 308 full-text articles were assessed for eligibility and 274 articles (417 studies) meeting the inclusion criteria were identified and included in the review. Almost half of the studies (49.6%) were conducted in European countries. The vast majority of the studies (85.7%) were carried out on samples of adult respondents. The research presents antecedents as well as (potential) consequences of conspiracy beliefs. We grouped the antecedents of conspiracy beliefs into six categories: cognitive (e.g., thinking style) motivational (e.g., uncertainty avoidance), personality (e.g., collective narcissism), psychopathology (e.g., Dark Triad traits), political (e.g., ideological orientation), and sociocultural factors (e.g., collectivism).

Conclusion and limitations

The research presents evidence on the links between conspiracy beliefs and a range of attitudes and behaviors considered unfavorable from the point of view of individuals and of the society at large. It turned out that different constructs of conspiracy thinking interact with each other. The limitations of the study are discussed in the last part of the article.

Scientific reasoning is associated with rejection of unfounded health beliefs and adherence to evidence-based regulations during the Covid-19 pandemic

Scientific reasoning and trust in science are two facets of science understanding. This paper examines the contribution of science understanding, over and above analytic thinking, to the endorsement of conspiracy and pseudoscientific beliefs about COVID-19 and behavioral intentions to engage in the recommended preventive behavior. We examined the direct and indirect effects of science understanding on normative health behavior in a representative sample of the Slovak population (N = 1024). The results showed more support for the indirect pathway: individuals with a better understanding of science generally had fewer epistemically suspect beliefs and as a consequence tended to behave more in line with the evidence-based guidelines and get vaccinated. Neither scientific reasoning nor trust in science directly predicted non-compliance with preventive measures, but analytic thinking correlated positively with non-compliance with preventive measures. The strongest predictor of epistemically suspect beliefs was trust in science, which also directly predicted the intention to get vaccinated against COVID-19. Therefore, reasoning about which experts or sources to believe (second-order scientific reasoning) has become more important than directly evaluating the original evidence (first-order scientific reasoning).

Conspiracy beliefs and COVID-19 guideline adherence in adolescent psychiatric outpatients: the predictive role of adverse childhood experiences

BACKGROUND

Conspiracy beliefs have become widespread throughout the COVID-19 pandemic. Previous studies have shown that endorsing conspiracy beliefs leads to lower protective guideline adherence (i.e., wearing face masks), posing a threat to public health measures. The current study expands this research across the lifespan, i.e., in a sample of adolescents with mental health problems. Here, we investigated the association between conspiracy beliefs and guideline adherence while also exploring the predictors of conspiracy beliefs.

METHODS

N = 93 adolescent psychiatric outpatients (57% female, mean age: 15.8) were assessed using anonymous paper-pencil questionnaires. Endorsement of generic and COVID-19 conspiracy beliefs was assessed, in addition to items measuring adherence to protective guidelines and mental health (stress, depressive symptoms, emotional/behavioral problems, and adverse childhood experiences). Multiple regressions and supervised machine learning (conditional random forests) were used for analyses.

RESULTS

Fourteen percent of our sample fully endorsed at least one COVID-19 conspiracy theory, while protective guidelines adherence was relatively high (M = 4.92, on a scale from 1 to 7). The endorsement of COVID-19 conspiracy beliefs-but not of generic conspiracy beliefs-was associated with lower guideline adherence (β = - 0.32, 95% CI - 0.53 to - 0.11, p < .001). Conditional random forests suggested that adverse childhood experiences and peer and conduct problems were relevant predictors of both conspiracy belief categories.

CONCLUSION

While a significant proportion of our sample of adolescents in psychiatric treatment endorsed conspiracy beliefs, the majority did not. Furthermore, and to some degree, contrary to public perception, we found that adolescents show relatively good adherence to public health measures-even while experiencing a high degree of mental distress. The predictive value of adverse childhood experiences and peer/conduct problems for conspiracy beliefs might be explained by compensatory mechanisms to ensure the safety, structure, and inclusion that conspiracies provide.

Mobile opportunity against stress: Open study protocol on the effectiveness of a mobile platform for stress self-management in the post-pandemic era

Mobile health platforms have shown promise in the management of various mental health conditions (including stress, anxiety, and depression) and cognitive behavioral strategies emerged as a popular and effective option offered by the platforms. This paper presents the protocol of a study aimed to test the effectiveness of a mobile platform that uses cognitive-behavioral strategies for stress self-management in the Tuscany region (Italy). The mobile app is adapted to the specific needs of each vulnerable population for which it is designed: young and older people, healthcare professionals, entrepreneurs. The app will be evaluated on the following outcomes: (i) perceived susceptibility and severity of the pandemic situation, perceived benefits, and costs of preventive health behaviors, (ii) knowledge about Covid-19 preventive behaviors and negative consequences of social distancing, (iii) stress and psychopathological symptoms (i.e., anxiety, depression, and post-traumatic stress symptoms) and cognitive distortions. If successful, we expect that the platform could give various groups clinical benefits by providing symptom self-monitoring and early intervention, consolidating the number of mental health programs available, and decreasing barriers to treatment-seeking. This population-level approach has the potential to improve mental health outcomes in pandemic periods for many people.

The response to the COVID-19 pandemic: With hindsight what lessons can we learn?

The purpose of this paper is to put forward some evidence-based lessons that can be learned from how to respond to a Pandemic that relate to healthy living behaviours (HLB). A 4-step methodology was followed to conduct a narrative review of the literature and to present a professional practice vignette. The narrative review identified 8 lessons: 1) peer review; 2) historical perspectives; 3) investing in resilience and protection; 4) unintended consequences; 5) protecting physical activity; 6) school closures; 7) mental health; and 8) obesity. As in all probability there will be another Pandemic, it is important that the lessons learned over the last three years in relation to HLB are acted upon. Whilst there will not always be a consensus on what to emphasise, it is important that many evidence-based positions are presented. The authors of this paper recognise that this work is a starting point and that the lessons presented here will need to be revisited as new evidence becomes available.

A single exposure to cancer misinformation may not significantly affect related behavioural intentions

Background: In recent years, rates of online cancer misinformation have grown, with many concerned that this could lead patients to alter their daily behaviours or forego conventional treatment. However, no published study has investigated whether exposure to cancer misinformation can affect health behaviours or behavioural intentions. Method: In this preregistered study, participants (N = 774) were exposed to cancer misinformation in the form of news stories before rating their intentions to engage in related behaviours. Each participant was randomly presented with two of four possible false cancer headlines such as “Drinking fluoridated water shown to increase cancer risk by a factor of 3”, before rating their intentions to engage in certain behaviours (such as avoiding fluoridated water). Participants were also randomly assigned to either an accuracy-nudge intervention intended to reduce susceptibility to misinformation or a control condition with no intervention. Results: Viewing the fake cancer headlines did not significantly affect participants’ behavioural intentions – e.g., those who saw the headline regarding fluoridated water were not more likely to report intentions to reduce their fluoridated water intake. The accuracy-nudge intervention did not affect behavioural intentions. Conclusion: Although cancer misinformation is considered a threat to public health, we conclude that once-off exposures to cancer misinformation may not be sufficient to significantly alter behavioural intentions. We note that claims about the effects of cancer misinformation on behaviour have not been adequately researched and we therefore call for more research into the behavioural effects of cancer misinformation exposure, particularly repeated exposure or information passed from trusted sources.

Varieties of corona news: a cross-national study on the foundations of online misinformation production during the COVID-19 pandemic

Misinformation in the media is produced by hard-to-gauge thought mechanisms employed by individuals or collectivities. In this paper, we shed light on what the country-specific factors of falsehood production in the context of COVID-19 Pandemic might be. Collecting our evidence from the largest misinformation dataset used in the COVID-19 misinformation literature with close to 11,000 pieces of falsehood, we explore patterns of misinformation production by employing a variety of methodological tools including algorithms for text similarity, clustering, network distances, and other statistical tools. Covering news produced in a span of more than 14 months, our paper also differentiates itself by its use of carefully controlled hand-labeling of topics of falsehood. Findings suggest that country-level factors do not provide the strongest support for predicting outcomes of falsehood, except for one phenomenon: in countries with serious press freedom problems and low human development, the mostly unknown authors of misinformation tend to focus on similar content. In addition, the intensity of discussion on animals, predictions and symptoms as part of fake news is the biggest differentiator between nations; whereas news on conspiracies, medical equipment and risk factors offer the least explanation to differentiate. Based on those findings, we discuss some distinct public health and communication strategies to dispel misinformation in countries with particular characteristics. We also emphasize that a global action plan against misinformation is needed given the highly globalized nature of the online media environment.

Summarising data and factors associated with COVID-19 related conspiracy theories in the first year of the pandemic: a systematic review and narrative synthesis

Conspiracy theories can have particularly harmful effects by negatively shaping health-related behaviours. A significant number of COVID-19 specific conspiracy theories emerged in the immediate aftermath of the pandemic outbreak. The aim of this study was to systematically review the literature on conspiracy theories related to COVID-19 during the first year of the pandemic (2020), to identify their prevalence, their determinants and their public health consequences. A comprehensive literature search was carried out in PubMed and PsycINFO to detect all studies examining any conspiracy theory related to COVID-19 between January 1st 2020, and January 10th 2021. Forty-three studies were included with a total of 61,809 participants. Between 0.4 and 82.7% of participants agreed with at least one conspiracy belief. Certain sociodemographic factors (young age, female gender, being non-white, lower socioeconomic status), psychological aspects (pessimism, blaming others, anger) and other qualities (political conservatism, religiosity, mistrust in science and using social media as source of information) were associated with increased acceptance of conspiracy theories. Conspiracy beliefs led to harmful health-related behaviours and posed a serious public health threat. Large-scale collaborations between governments and healthcare organizations are needed to curb the spread of conspiracy theories and their adverse consequences.

It is probably a pattern: does spontaneous focusing on regularities in preschool predict reasoning about randomness four years later?

The many studies with coin-tossing tasks in literature show that the concept of randomness is challenging for adults as well as children. Systematic errors observed in coin-tossing tasks are often related to the representativeness heuristic, which refers to a mental shortcut that is used to judge randomness by evaluating how well a set of random events represents the typical example for random events we hold in our mind. Representative thinking is explained by our tendency to seek for patterns in our surroundings. In the present study, predictions of coin-tosses of 302 third-graders were explored. Findings suggest that in third grade of elementary school, children make correct as well as different types of erroneous predictions and individual differences exist. Moreover, erroneous predictions that were in line with representative thinking were positively associated with an early spontaneous focus on regularities, which was assessed when they were in second year of preschool. We concluded that previous studies might have underestimated children's reasoning about randomness in coin-tossing contexts and that representative thinking is indeed associated with pattern-based thinking tendencies.

COVID-19 related conspiracy beliefs and their relationship with defense strategies, emotions, powerlessness, attitudes, and time perspective

The COVID-19 pandemic has greatly impacted individual's life and society, and such an emergency has increased the likelihood of recurring conspiratorial thinking. There is much research on broader conspiratorial thinking and studies on COVID-19-related conspiratorial thinking has been growing worldwide, moreover, the negative consequences of COVID-19 specific conspiratorial beliefs for people's health are clear. However, person-centered research aiming at identify groups of individuals who share patterns of relations between COVID-19 specific conspiratorial beliefs and other psychological features is still scarce. A sample of 1.002 people (18-40 years old, M = 23; SD = 5.19) responded to a questionnaire administered online. The aim was to identify groups of individuals based on their beliefs about COVID-19 conspiracy theories and to compare the groups identified in terms of psychological characteristics associated such as automatic defense mechanisms, coping strategies, powerlessness, emotions, emotional regulation, attitudes toward the COVID-19, social distancing discontent, perceptions of COVID-19 severity and temporal perspective. A k-mean cluster analysis identified the groups of Believers (22.26%), Ambivalent believers (34.3%), and Non-believers (43.21%). The three groups differ particularly in terms of defense mechanisms, and time perspective. Results suggested the need to tailor interventions for individuals believing in COVID-19 conspiratorial theories based on differences in the psychological characteristics among the three groups.

Measuring the effects of misinformation exposure and beliefs on behavioural intentions: a COVID-19 vaccination study

Misinformation has been a pressing issue since the beginning of the COVID-19 pandemic, threatening our ability to effectively act on the crisis. Nevertheless, little is known about the actual effects of fake news on behavioural intentions. Does exposure to or belief in misinformation about COVID-19 vaccines affect people's intentions to receive such a vaccine? This paper attempts to address this question via three preregistered experiments (N = 3463). In Study 1, participants (n = 1269) were exposed to fabricated pro- or anti-vaccine information or to neutral true information, and then asked about their intentions to get vaccinated. In Study 2, participants (n = 646) were exposed to true pro- and anti-vaccine information, while Study 3 (n = 1548) experimentally manipulated beliefs in novel misinformation about COVID-19 vaccines by increasing exposure to the information. The results of these three studies showed that exposure to false information about the vaccines had little effect on participants' intentions to get vaccinated, even when multiple exposures led them to believe the headlines to be more accurate. An exploratory meta-analysis of studies 1 and 3, with a combined sample size of 2683, showed that exposure to false information both supporting and opposing COVID-19 vaccines actually increased vaccination intentions, though the effect size was very small. We conclude by cautioning researchers against equating exposure to misinformation or perceived accuracy of false news with actual behaviours.

COVID-19 vaccine hesitancy and its associated factors in Malaysia

The success of the COVID-19 vaccination programme to achieve herd immunity depends on the proportion of the population inoculated. COVID-19 vaccination hesitancy is a barrier to reaching a sufficient number of people to achieve herd immunity. This study aims to determine the prevalence of COVID-19 vaccine hesitancy and to identify the reasons contributing to vaccine hesitancy using the Theory of Planned Behavior. A cross-sectional online survey was conducted between May 2021 to June 2021. Using exponential non-discriminative snowball sampling, participants were recruited via social media and telecommunication platforms. We used a questionnaire that obtained information on participant socio-demographics, vaccine hesitancy, pseudoscientific practices, conspiracy beliefs, subjective norms, perceived behavioural control, main reasons for not intending to get the COVID-19 vaccine; influential leaders, gatekeepers and anti-or pro-vaccination lobbies; and global vaccine hesitancy. A total of 354 responses (mean age = 32.5 years old ±13.6; 70.3% females) were included for analysis. The prevalence of COVID-19 vaccine hesitancy was 11.6%. COVID-19 vaccine hesitancy was significantly and positively associated with those who agreed with influential leaders, gatekeepers, and anti- or pro-vaccination lobbies (adjusted B coefficient = 1.355, p = 0.014), having a “wait and see” attitude to see if the COVID-19 vaccine is safe (adjusted B coefficient = 0. 822, p <0.001), perceiving that the vaccine will give them COVID-19 (adjusted B coefficient = 0.660, p <0.002), planned to use masks/others precautions instead (adjusted B coefficient = 0.345, p = 0.038) and having higher scores in conspiracy beliefs (adjusted B coefficient = 0.128, p <0.001). Concern about the costs associated with the vaccine (adjusted B coefficient = -0.518, p <0.001), subjective norms (adjusted B coefficient = -0.341, p <0.001), and perceived behavioural control (adjusted B coefficient = -0.202, p = 0.004) were negatively associated with vaccine hesitancy. COVID-19 vaccine hesitancy in Malaysia is low. Several factors were identified as being associated with vaccine hesitancy. Factors associated with vaccine hesitancy would be useful in tailoring specific interventions involving positive messages by influential leaders, which address vaccine misinformation and the wait-and-see attitude which may delay the uptake of COVID-19 vaccines.

Imagining the Post-COVID-19 Polity: Narratives of Possible Futures

The COVID-19 crisis is arguably the most important development of the 21st century so far and takes its place alongside the great eruptions of the past century. As with any crisis, the current pandemic has stimulated visions and proposals for post-COVID-19 societies. Our focus is on narratives—both predictive and prescriptive—that envisage post-COVID-19 political societies. Combining narrative analysis with thematic analysis, we argue that societal changes conditioned by the pandemic have accelerated a turn toward five inter-related developments: A renaissance in rationality and evidence-based science; a return to social equality and equity, including wage equity and guaranteed incomes; a reimagining of the interventionist state in response to crises in the economy, society, the welfare state, and social order; a reorientation to the local and communitarian, with reference in particular to solidaristic mutual aid, community animation, local sourcing, and craft production; and the reinvention of democracy through deep participation and deliberative dialogical decision making. The empirical focus of our work is an analysis of predominantly legacy media content from the Canadian Periodicals Index related to life after the pandemic and post-COVID-19 society.

Predictors of COVID-19 Vaccine Intention: Evidence from Chile, Mexico, and Colombia

(1) Background: Although the evidence is consistent that vaccines for COVID-19 effectively prevent severe illness or death, the rapid development of vaccines has led to increased beliefs about possible negative consequences and conspiracy theories about the vaccine. Several factors influence whether or not people decide to be vaccinated. Some studies suggest that our perception of what significant others do and think influences our behavior. (2) Methods: This study evaluates the predictive role of beliefs about negative consequences of the COVID-19 vaccine, conspiracy beliefs about this vaccine, and social influence on the intention to vaccinate against COVID-19 in three Latin American and Caribbean countries: Chile, Mexico, and Colombia. Using convenience sampling, 2075 adults from Chile (48.3%), Mexico (27.6%), and Colombia (24.6%) participated by answering an online questionnaire with variables of interest. (3) Results: Despite the differences between countries, the results showed that the proposed model is invariant and explains between 56-66% of the COVID-19 vaccination intent. Specifically, controlling for age, socioeconomic status, political orientation, and educational level, we found that beliefs about the negative consequences of the COVID-19 vaccine were the main predictor followed by social influence. Beliefs in conspiracy theories did not predict vaccination intention (4) Conclusions: Considering these variables in campaigns to boost vaccination intention is discussed.

COVID-19 vaccine hesitancy and acceptance: a comprehensive scoping review of global literature

As countries continue the third year of the pandemic, we believe that there has been unfair attention to COVID-19 vaccine efficacy and safety, while tacitly ignoring serious challenges with vaccine uptake, without which vaccination may not be effective against the spread of COVID-19. While several studies have been published on COVID-19 vaccine hesitancy, there remains a need to conduct a comprehensive global analysis of vaccine hesitancy. We conducted a scoping review of 60 studies published globally on vaccine hesitancy and acceptance. We conducted a qualitative analysis to identify motivators and barriers to vaccination across several cultural and demographic contexts. We found the following factors to be relevant in any discussion about addressing or minimizing vaccine hesitancy: risk perceptions, trust in health care systems, solidarity, previous experiences with vaccines, misinformation, concerns about vaccine side effects and political ideology. We combine our insights from this comprehensive review of global literature to offer an important and practical discussion about two strategies that have been used to improve vaccine uptake: (i) communication and education and (ii) vaccine rollout and logistics.

Antecedents and consequences of COVID-19 conspiracy beliefs: A systematic review

RATIONALE

Belief in COVID-19 conspiracy theories can have severe consequences; it is therefore crucial to understand this phenomenon, in its similarities with general conspiracy belief, but also in how it is context-dependent.

OBJECTIVE

The aim of this systematic review is to provide a comprehensive overview of the available research on COVID-19 conspiracy beliefs and to synthesise this research to make it widely accessible.

METHODS

We present a synthesis of COVID-19 conspiracy belief research from 85 international articles, identified and appraised through a systematic review, in line with contemporary protocols and guidelines for systematic reviews.

RESULTS

We identify a number of potential antecedents of COVID-19 conspiracy beliefs (individual differences, personality traits, demographic variables, attitudes, thinking styles and biases, group identity, trust in authorities, and social media use), their consequences (protective behaviours, self-centred and misguided behaviours such as hoarding and pseudoscientific health practices, vaccination intentions, psychological wellbeing, and other negative social consequences such as discrimination and violence), and the effect sizes of their relations with the conspiracy beliefs.

CONCLUSIONS

We conclude that understanding both the potential antecedents and consequences of conspiracy beliefs and how they are context-dependent is highly important to tackle them, whether in the COVID-19 pandemic or future threats, such as that of climate change.

Psychological underpinnings of pandemic denial - patterns of disagreement with scientific experts in the German public during the COVID-19 pandemic

We investigated pandemic denial in the general public in Germany after the first wave of COVID-19 in May 2020. Using latent class analysis, we compared patterns of disagreement with claims about (a) the origin, spread, or infectiousness of the SARS-CoV-2 virus and (b) the personal risk from COVID-19 between scientific laypersons (N = 1,575) and scientific experts (N = 128). Two groups in the general public differed distinctively from expert evaluations. The Dismissive (8%) are characterized by low-risk assessment, low compliance with containment measures, and mistrust in politicians. The Doubtful (19%) are characterized by low cognitive reflection, high uncertainty in the distinction between true and false claims, and high social media intake. Our research indicates that pandemic denial cannot be linked to a single and distinct pattern of psychological dispositions but involves different subgroups within the general population that share high COVID-19 conspiracy beliefs and low beliefs in epistemic complexity.

Determinants of the Hesitancy toward COVID-19 Vaccination in Eastern European Countries and the Relationship with Health and Vaccine Literacy: A Literature Review

Herd immunity is necessary to control the coronavirus disease 2019 (COVID-19) pandemic. However, a low proportion of vaccinated people and low levels of vaccine acceptance have been noted in Eastern Europe. Our paper aimed to review the central attitudes associated with the hesitancy toward COVID-19 vaccination specific to Eastern European countries. The main Eastern European determinants of COVID-19 vaccine acceptance identified from the included studies are: public confidence in the vaccines’ safety and efficacy, vaccine literacy, and public trust in the government and the medical system. Each of these determinants is discussed along with possible improvement measures. Variables specific to Eastern Europe that predict the willingness to vaccinate have also been highlighted. The specific attitudes and their context as identified by our review should be incorporated into local public health programs, with the ultimate goal of reducing viral spreading, mutation emergence, and COVID-19 morbidity and mortality both within the borders of Eastern Europe and beyond.

Explaining Resistance to the COVID-19 Preventive Measures: A Psychological Reactance Perspective

This paper examines the impact that psychological reactance has on the COVID-19 adherence-related behavior and vaccine motivations of the residents of Saudi Arabia. A cross-sectional, online survey was administered, and 604 usable responses were analyzed to discover the level of psychological reactance, and its impact on adherence to COVID-19 preventive measures and vaccine intentions. Results of the Kruskal–Wallis H test demonstrated statistically significant evidence (p < 0.05) of differences between the mean ranks for four out of seven key COVID-19 preventive measures studied, and four out of five items related to vaccine motivations, as a result of psychological reactance. These results suggest that while the majority of the population is adhering to COVID-19 preventive measures, for the subset of the population that are not fully compliant, psychological reactance is a significant factor in influencing behavior. Governments are, therefore, recommended to ensure that their public health messages are autonomy supporting, and take into consideration psychological and personality-based differences in individuals.

You before me: How vertical collectivism and feelings of threat predicted more socially desirable behaviour during COVID-19 pandemic

The present study investigated the relationship between outward orientation and COVID-related prosocial behavior, including adherence to containment measures, caring for others and providing support, limiting one's social life and responsible purchasing behavior. A sample of 500 Slovaks (250 women) aged between 18 and 86 (M = 44.32, SD = 15.66) participated in the study and responded to questions concerning their sociodemographic and personality characteristics, collectivism and individualism, the consciousness of future consequences and emotional responses to the pandemic. The results show that apart from the perceived threat of COVID-19, vertical collectivism is among the strongest antecedents of COVID-related prosocial behavior. Specifically, feelings of threat, vertical collectivism, conscientiousness, agreeableness, liberalism, and education predicted more prosocial behavior during the pandemic. Consequently, the study indicates that while excessive fear may have adverse effects on individuals' well-being, appealing to and cultivating collectivistic sentiments could contribute not only to containing the pandemic but also to making others' lives more bearable while it lasts.

Systematic review on the association of COVID-19-related conspiracy belief with infection-preventive behavior and vaccination willingness

BACKGROUND

In times of a pandemic, not only infections but also conspiracy narratives spread among people. These have the potential to influence the course of the pandemic. Here we summarize and critically evaluate studies from the first year of the pandemic presenting findings on the association between COVID-19-related conspiracy belief and infection-preventive behavior and vaccination willingness.

METHOD

A systematic literature search was conducted using the databases COVID-19 Data Portal, APA PsycArticles, Psychology and Behavioral Sciences, Scopus, and PubMed. After removing duplicates, studies meeting the previously defined inclusion and exclusion criteria were subjected to title and abstract screening and content reviewed and analyzed subsequently.

RESULTS AND CONCLUSION

The systematic literature search yielded 17 studies meeting our pre-specified inclusion criteria. Twelve studies examined infection-preventive behavior (N = 16,485), and ten studies vaccination willingness (N = 20,210). In summary, belief in COVID-19-related conspiracy narratives was negatively associated with vaccination willingness and infection-preventive behavior. The results point to the importance of the content of the conspiracy narratives. Various explanatory approaches and possible moderator variables are discussed, referencing the state of research on conspiracy beliefs and health-related preventive behavior after the first year of the pandemic. We argue that future studies should strive for a consistent operationalization and use of the term conspiracy belief.

Acceptance and Adherence to COVID-19 Preventive Measures are Shaped Predominantly by Conspiracy Beliefs, Mistrust in Science and Fear - A Comparison of More than 20 Psychological Variables

The global coronavirus (COVID-19) pandemic sparked a great interest in psychological factors that determine or explain peoples' responses to the novel threatening situation and the preventive measures (e.g. wearing masks, social distancing). In this study, we focused on contaminated mindware (conspiracy and paranormal beliefs) and investigated its relationship with both acceptance of and adherence to COVID-19 preventive measures, along with other variables from the domains of emotion (trait anxiety, fear), traditional personality traits (Big 5, locus of control, optimism/pessimism) and motivation (self-control, dispositional regulatory focus). A total of 22 variables were measured in an online survey (N = 374) that took place during the second wave of COVID-19 (Nov. 2020 – March 2021) in Switzerland. Of all variables, the endorsement of specific COVID-19 conspiracy beliefs was most strongly associated with lower acceptance and adherence to the preventive measures, together with mistrust in science and a more right-wing political orientation. In contrast, fear of COVID-19 and prevention regulatory focus were positively associated with acceptance and adherence. Our results therefore highlight the importance of fighting (conspiratorial) misinformation and of increasing the perceived credibility of science in reducing the spread of the coronavirus. Moreover, when acceptance was used as predictor for adherence, agreeableness and dispositional prevention regulatory focus still explained unique variance in adherence, suggesting that such personality and motivational variables play an important role in adhering and regulating preventive behaviour independent from the attitude towards the preventive measures themselves.

Willingness to vaccinate against SARS-CoV-2: The role of reasoning biases and conspiracist ideation

BACKGR1OUND: Widespread vaccine hesitancy and refusal complicate containment of the SARS-CoV-2 pandemic. Extant research indicates that biased reasoning and conspiracist ideation discourage vaccination. However, causal pathways from these constructs to vaccine hesitancy and refusal remain underspecified, impeding efforts to intervene and increase vaccine uptake.

METHOD

554 participants who denied prior SARS-CoV-2 vaccination completed self-report measures of SARS-CoV-2 vaccine intentions, conspiracist ideation, and constructs from the Health Belief Model of medical decision-making (such as perceived vaccine dangerousness) along with tasks measuring reasoning biases (such as those concerning data gathering behavior). Cutting-edge machine learning algorithms (Greedy Fast Causal Inference) and psychometric network analysis were used to elucidate causal pathways to (and from) vaccine intentions.

RESULTS

Results indicated that a bias toward reduced data gathering during reasoning may cause paranoia, increasing the perceived dangerousness of vaccines and thereby reducing willingness to vaccinate. Existing interventions that target data gathering and paranoia therefore hold promise for encouraging vaccination. Additionally, reduced willingness to vaccinate was identified as a likely cause of belief in conspiracy theories, subverting the common assumption that the opposite causal relation exists. Finally, perceived severity of SARS-CoV-2 infection and perceived vaccine dangerousness (but not effectiveness) were potential direct causes of willingness to vaccinate, providing partial support for the Health Belief Model's applicability to SARS-CoV-2 vaccine decisions.

CONCLUSIONS

These insights significantly advance our understanding of the underpinnings of vaccine intentions and should scaffold efforts to prepare more effective interventions on hesitancy for deployment during future pandemics.

Finding Someone to Blame: The Link Between COVID-19 Conspiracy Beliefs, Prejudice, Support for Violence, and Other Negative Social Outcomes

One of the appeals of conspiracy theories in times of crises is that they provide someone to blame for what has happened. Thereby, they increase distrust, negative feelings, and hostility toward implicated actors, whether those are powerful social outgroups or one's own government representatives. Two studies reported here examine associations of COVID-19 conspiracy theories with prejudice, support for violence, and other and negative social outcomes. In Study 1 (N = 501), the endorsement of the more specific conspiracy theories about the alleged role of China was associated with more prejudiced views of Chinese and Italian people. In Study 2 (N = 1024), lowered trust in government regulations and increased hostility associated with the COVID-19 and generic conspiracy beliefs were correlated with justification of and willingness to engage in non-compliance with regulations, violent attacks on 5G masts, and anti-government protests. Across both of the studies, higher exposure to news about COVID-19 was associated with lower endorsement of conspiracy theories, but also with increased feelings of anxiety and lack of control, which in turn were correlated with higher COVID-19 conspiracy beliefs endorsement. We highlight the potential social problems which are associated with the wide-spread endorsement of COVID-19 conspiracy theories.

Political affiliation moderates subjective interpretations of COVID-19 graphs

We examined the relationship between political affiliation, perceptual (percentage, slope) estimates, and subjective judgements of disease prevalence and mortality across three chart types. An online survey (N = 787) exposed separate groups of participants to charts displaying (a) COVID-19 data or (b) COVID-19 data labeled 'Influenza (Flu)'. Block 1 examined responses to cross-sectional mortality data (bar graphs, treemaps); results revealed that perceptual estimates comparing mortality in two countries were similar across political affiliations and chart types (all ps > .05), while subjective judgements revealed a disease x political party interaction (p < .05). Although Democrats and Republicans provided similar proportion estimates, Democrats interpreted mortality to be higher than Republicans; Democrats also interpreted mortality to be higher for COVID-19 than Influenza. Block 2 examined responses to time series (line graphs); Democrats and Republicans estimated greater slopes for COVID-19 trend lines than Influenza lines (p < .001); subjective judgements revealed a disease x political party interaction (p < .05). Democrats and Republicans indicated similar subjective rates of change for COVID-19 trends, and Democrats indicated lower subjective rates of change for Influenza than in any other condition. Thus, while Democrats and Republicans saw the graphs similarly in terms of percentages and line slopes, their subjective interpretations diverged. While we may see graphs of infectious disease data similarly from a purely mathematical or geometric perspective, our political affiliations may moderate how we subjectively interpret the data.
