Is the worship of celebrities associated with resistance to vaccinations? Relationships between celebrity admiration, anti-vaccination attitudes, and beliefs in conspiracy

Health misinformation and freedom of expression: considerations for policymakers

Health misinformation, most visibly following the COVID-19 infodemic, is an urgent threat that hinders the success of public health policies. It likely contributed, and will continue to contribute, to avoidable deaths. Policymakers around the world are being pushed to tackle this problem. Legislative acts have been rolled out or announced in many countries and at the European Union level. The goal of this paper is not to review particular legislative initiatives, or to assess the impact and efficacy of measures implemented by digital intermediaries, but to reflect on the high constitutional and ethical stakes involved in tackling health misinformation through speech regulation. Our findings suggest that solutions focused on regulating speech are likely to encounter significant constraints, as policymakers grasp with the limitations imposed by freedom of expression and ethical considerations. Solutions focused on empowering individuals - such as media literacy initiatives, fact-checking or credibility labels - are one way to avoid such hurdles.

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.

Psychological mechanisms and interventions directed at vaccination attitudes

Attitudes about vaccination impact not only the individual but also society. Therefore, understanding the underlying psychological processes of those who disagree with vaccination is critical for creating compassion through understanding and change through promoting autonomy. The current review aimed to fill a gap in the literature, outlining the state of the recent research on vaccination attitudes, specifically on the underlying mechanisms driving anti-vaccination movements and individuals' thoughts and behaviors. In addition, we aimed to evaluate current research on the effectiveness of interventions targeting these mechanisms. Overall, results indicated that those declining vaccines had beliefs related to distrust in the scientific community and pharmaceutical companies and moral preferences for purity and liberty. In addition, our review identified the potential for utilizing motivational interviewing techniques as an intervention. This literature review provides a platform for further research and enhances the current understanding of vaccination attitudes.

Is Loneliness Associated With Celebrity Attraction in LGBT+ Persons?

The present study is a conceptual replication of the functional alternative hypothesis, which states that when it is difficult for some persons to form satisfactory interpersonal relationships they turn to parasocial relationships as a functional alternative. In this study, the Celebrity Attitude Scale (CAS), a one-item measure of interest in celebrities in general, the Five-item Adaptation of the Revised UCLA Loneliness Scale (FALS), and the Receiving Emotional Support Subscale (RESS) were administered to 222 self-identified LGBT+ and 436 self-identified heterosexual persons from the Philippines aged 18 to 77 years old. We hypothesized that sexual orientation would moderate the relationship between loneliness and celebrity worship, such that the association between loneliness and celebrity worship would be stronger among LGBT+ individuals than among heterosexual individuals. This hypothesis was confirmed when the target person was one's favorite celebrity. Second, we hypothesized that lower levels of perceived social support among LGBT+ Filipinos would be associated with a stronger correlation between loneliness and celebrity worship as compared to LGBT+ Filipinos with a higher level of social support. Third, we hypothesized that younger LGBT+ persons would have a stronger association between loneliness and celebrity worship as compared to older LGBT+ persons. Results failed to confirm the social support and age hypotheses. The findings and limitations were discussed, and suggestions for further research were noted.

Examining four types of anti-vaccination attitudes prior to and during the COVID-19 pandemic

People hold different anti-vaccination attitudes. Having an understanding of how these attitudes have changed prior to and during the COVID-19 pandemic is critical for combatting anti-vaccination attitudes and increasing vaccine intention and uptake. Data were collected from different samples in the United States at three time points prior to (n = 840) and four time points during (n = 1543) the pandemic. All participants completed a multi-dimensional measure of anti-vaccination attitudes (VAX Scale) through an online platform. Results showed that, when it comes to vaccines, worries about unforeseen side effects, concerns about commercial profiteering, and preference for natural immunity were higher during the COVID-19 pandemic than they were prior to it. However, mistrust of vaccine benefit was lower during the COVID-19 pandemic than prior to it. These differences were found even after controlling for the potential effects of participant sex, education, socioeconomic status, age, and race/ethnicity. Additionally, worries about unforeseen side effects, concerns about commercial profiteering, and preference for natural immunity increased linearly alongside the persistence of COVID-19; whereas, mistrust of vaccine benefit showed no change. Although it might be intuitive to emphasize vaccines' effectiveness to increase uptake, the public's trust in vaccine effectiveness did not appear to be the major concern. Thus, public health efforts to increase uptake of vaccines should also focus on reducing concerns about potential side effects from the vaccine, tempering the attention on financial benefits to pharmaceutical companies, and rebuffing the overreliance on natural immunity.

Using what we know about threat reactivity models to understand mental health during the COVID-19 pandemic

The COVID-19 pandemic has been accompanied by unprecedented levels of stress and threats in a variety of domains (e.g., health, livelihood). Individual differences in threat reactivity may explain why some individuals are at elevated risk for the development or maintenance of psychopathology during the COVID-19 pandemic. This article describes several prominent models, mechanisms, and components of threat reactivity (e.g., appraisals, intolerance of uncertainty, avoidance) and discusses how they might help improve understanding of changes in psychopathology during and following the COVID-19 pandemic.

Science and behavioral intentions among Israeli Jewish ultra-Orthodox males: Death from COVID-19 or from the COVID-19 vaccine? A thematic study

The COVID-19 vaccine is a scientific breakthrough to end the pandemic. We explore perceptions underlying behavioral intentions toward the COVID-19 vaccine among ultra-Orthodox Jewish males in Israel upon rollout of the vaccine. Forty-two men aged 36-56 years participated in in-depth interviews. The theoretical anchor is Miller's theory of scientific literacy. The research questions are "What perceptions shape rejection of the COVID-19 vaccine?" "What perceptions shape hesitancy and deterrence toward the COVID-19 vaccine?" and "What social forces shape behavioral intentions toward the COVID-19 vaccine?" Thematic data analysis demonstrated six themes of vaccine rejection and four themes of hesitation toward vaccination. The social forces shaping behavioral intentions are the local community's leader and the national religious authority. We highlight the need to enhance scientific literacy and reduce suspicion through collaborative community-based work among health professionals from the community, religious leaders, and lay leaders to increase acceptance of the COVID-19 vaccine.

Psychosocial Predictors of Intention to Vaccinate Against the Coronavirus (COVID-19)

The COVID-19 pandemic has wreaked havoc across the world. Public health efforts to combat the disease and return life to normalcy largely rests upon COVID-19 vaccination distribution and uptake. Thus, it is critical to examine factors that predict people's intentions to vaccinate. This study explored predictors of intention to vaccinate against COVID-19 among demographic and personal factors, health behaviors and beliefs, COVID-19-specific beliefs, and trust in physicians, using a sample of U.S. adults. We employed bivariate correlations and hierarchical regression to analyze the data. We found that the strongest predictors are political orientation, trust in physicians, subjective norms, and prior flu shot uptake. These associations suggest that individuals who held more liberal political views, expressed higher levels of trust in their primary care provider, perceived stronger social pressure to vaccinate against COVID-19, and received a flu shot during the previous flu season, had a stronger intention to vaccinate against COVID-19. Based on our results, we suggest that public health efforts to increase vaccination uptake for COVID-19 vaccines focus on addressing political orientation (conservatism), involve primary care providers, emphasize vaccination as the norm (and not the exception), and use information about previous flu vaccinations to target vaccination campaigns.

A little shot of humility: Intellectual humility predicts vaccination attitudes and intention to vaccinate against COVID-19

Vaccinations remain a critical, albeit surprisingly controversial, health behavior, especially with the promise of widely available COVID‐19 vaccine. Intellectual humility, a virtue characterized by nonjudgmental recognition of one's own intellectual fallibility, may counter rigidity associated with anti‐vaccination attitudes and help promote vaccine‐related behaviors. This study investigated whether intellectual humility is related to anti‐vaccination attitudes and intentions to vaccinate against COVID‐19, and whether intellectual humility can predict unique variance in these outcomes beyond participant demographic and personal factors. Participants (N = 351, 57.23% male, mean age = 37.41 years, SD = 11.51) completed a multidimensional measure for intellectual humility, the anti‐vaccination attitudes (VAX) scale, and a two‐item COVID‐19 vaccination intention scale. Bivariate correlations demonstrated that intellectual humility was negatively related with anti‐vaccination attitudes overall, r(349) = −.46, p < .001, and positively related to intentions to vaccinate against COVID‐19, r(349) = .20, p < .001. Hierarchical multiple regression revealed that intellectual humility predicted all four types anti‐vaccination attitudes, overall anti‐vaccination attitudes, and COVID‐19 vaccination intentions above and beyond demographic and personal factors (i.e., sex, race/ethnicity, age, education, socioeconomic status, and political orientation), ΔR² between .08 and .18, ps < .001. These results bolster intellectual humility as a malleable psychological factor to consider in efforts to combat anti‐vaccination attitudes and promote COVID‐19 vaccination uptake.

Conspiracy Beliefs, Rejection of Vaccination, and Support for hydroxychloroquine: A Conceptual Replication-Extension in the COVID-19 Pandemic Context

Many conspiracy theories appeared along with the COVID-19 pandemic. Since it is documented that conspiracy theories negatively affect vaccination intentions, these beliefs might become a crucial matter in the near future. We conducted two cross-sectional studies examining the relationship between COVID-19 conspiracy beliefs, vaccine attitudes, and the intention to be vaccinated against COVID-19 when a vaccine becomes available. We also examined how these beliefs predicted support for a controversial medical treatment, namely, chloroquine. In an exploratory study 1 (N = 409), two subdimensions of COVID-19 conspiracy beliefs were associated with negative attitudes toward vaccine science. These results were partly replicated and extended in a pre-registered study 2 (N = 396). Moreover, we found that COVID-19 conspiracy beliefs (among which, conspiracy beliefs about chloroquine), as well as a conspiracy mentality (i.e., predisposition to believe in conspiracy theories) negatively predicted participants' intentions to be vaccinated against COVID-19 in the future. Lastly, conspiracy beliefs predicted support for chloroquine as a treatment for COVID-19. Interestingly, none of the conspiracy beliefs referred to the dangers of the vaccines. Implications for the pandemic and potential responses are discussed.
