Collectivism predicts mask use during COVID-19

Masks and respirators for prevention of respiratory infections: a state of the science review

SUMMARYThis narrative review and meta-analysis summarizes a broad evidence base on the benefits-and also the practicalities, disbenefits, harms and personal, sociocultural and environmental impacts-of masks and masking. Our synthesis of evidence from over 100 published reviews and selected primary studies, including re-analyzing contested meta-analyses of key clinical trials, produced seven key findings. First, there is strong and consistent evidence for airborne transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and other respiratory pathogens. Second, masks are, if correctly and consistently worn, effective in reducing transmission of respiratory diseases and show a dose-response effect. Third, respirators are significantly more effective than medical or cloth masks. Fourth, mask mandates are, overall, effective in reducing community transmission of respiratory pathogens. Fifth, masks are important sociocultural symbols; non-adherence to masking is sometimes linked to political and ideological beliefs and to widely circulated mis- or disinformation. Sixth, while there is much evidence that masks are not generally harmful to the general population, masking may be relatively contraindicated in individuals with certain medical conditions, who may require exemption. Furthermore, certain groups (notably D/deaf people) are disadvantaged when others are masked. Finally, there are risks to the environment from single-use masks and respirators. We propose an agenda for future research, including improved characterization of the situations in which masking should be recommended or mandated; attention to comfort and acceptability; generalized and disability-focused communication support in settings where masks are worn; and development and testing of novel materials and designs for improved filtration, breathability, and environmental impact.

Attitudes, Beliefs, and Perceptions Associated with Mask Wearing within Four Racial and Ethnic Groups Early in the COVID-19 Pandemic

BACKGROUND

While previous studies have identified a range of factors associated with mask wearing in the US, little is known about drivers of mask-wearing among racial and ethnic minority groups. This analysis assessed whether factors positively associated with wearing a mask early in the pandemic differed between participants grouped by race/ethnicity (Hispanic, non-Hispanic Black, non-Hispanic Asian, and non-Hispanic White).

METHOD

Data were obtained from a US internet panel survey of 3217 respondents during May-November 2020 (weighted by race/ethnicity, age, gender, and education to the US national population). Within each of the four available racial/ethnic groups, crude and adjusted odds ratios (COR and AOR) were calculated using logistic regression to assess factors positively associated with wearing a mask. Adjusted models were controlled for age, gender, education, county COVID-19 case count, presence of a state-issued mask mandate, and interview month.

RESULTS

The following variables were most strongly positively associated with mask wearing (p<0.05) in each racial/ethnic group: Hispanic-seeing others wearing masks (AOR: 6.7), importance of wearing a mask combined with social distancing (AOR: 3.0); non-Hispanic Black-belief that wearing a mask would protect others from coronavirus (AOR: 5.1), reporting hearing that one should wear a mask (AOR: 3.6); non-Hispanic Asian-belief that people important to them believe they should wear a mask (COR: 5.1, not statistically significant); and non-Hispanic White-seeing others wearing masks (AOR: 3.1), importance of wearing a mask (AOR: 2.3).

CONCLUSION

Public health efforts to encourage mask wearing should consider the diversity of behavioral influences within different population groups.

Crucial and fragile: a multi-methods and multi-disciplinary study of cooperation in the aftermath of the COVID-19 pandemic

In addressing global pandemics, robust cooperation across nations, institutions, and individuals is paramount. However, navigating the complexities of individual versus collective interests, diverse group objectives, and varying societal norms and cultures makes fostering such cooperation challenging. This research delves deep into the dynamics of interpersonal cooperation during the COVID-19 pandemic in Canton Ticino, Switzerland, using an integrative approach that combines qualitative and experimental methodologies. Through a series of retrospective interviews and a lab-in-the-field experiment, we gained insights into the cooperation patterns of healthcare and manufacturing workers. Within healthcare, professionals grappled with escalating emergencies and deteriorating work conditions, resisting the "new normalcy" ushered in by the pandemic. Meanwhile, manufacturing workers adapted to the altered landscape, leveraging smart working strategies to carve out a fresh professional paradigm amidst novel challenges and opportunities. Across these contrasting narratives, the centrality of individual, institutional, and interpersonal factors in galvanizing cooperation was evident. Key drivers like established relational dynamics, mutual dependencies, and proactive leadership were particularly salient. Our experimental findings further reinforced some of these qualitative insights, underscoring the pivotal role of recognition and the detrimental effects of uncertainty on cooperative behaviors. While contextual and sample-related constraints exist, this study illuminates vital facets of cooperation during crises and lays the groundwork for future explorations into cooperative decision-making.

A single dose for me, A wealth of protection for us: The public health cost of individualism in the rollout of COVID-19 vaccine

OBJECTIVE

This study examines whether individualism weakens the effectiveness of the COVID-19 vaccine eligibility expansions in the United States in 2021, and assesses the associated social benefits or costs associated with individualism.

METHODS

We construct a county-level composite individualism index as a proxy of culture and the fraction of vaccine eligible population as a proxy of vaccination campaign (mean: 41.34%). We estimate whether the COVID-19 vaccine eligibility policy is less effective in promoting vaccine coverage, reducing in COVID-19 related hospitalization and death using a linear two-way fixed effect model in a sample of 2866 counties for the period between early December 2020 and July 1, 2021. We also test whether individualism shapes people's attitudes towards vaccine using a linear probability model in a sample of 625,308 individuals aged 18-65 (mean age: 43.3; 49% male; 59.1% non-Hispanic white, 19.1% Hispanic, 12% African American; 5.9% Asian) from the Household Pulse Survey.

RESULTS

The effects of expanded vaccine eligibility are diminished in counties with greater individualism, as evidenced by lower effectiveness in increasing vaccination rates and reducing outpatient doctor visits primarily for COVID-related symptoms and COVID deaths. Moreover, our results show that this cultural influence on attitudes towards vaccine is more pronounced among the less educated, but unrelated to race.

CONCLUSION

Assuming an average level of vaccine eligibility policies and an average intensity of individualism across the nation, we calculate that the average social cost associated with an individualistic culture amid the pandemic is approximately $50.044 billion, equivalent to 1.32% of the total U.S. health care spending in 2019. Our paper suggests that strategies to promote public policy compliance should be tailored to accommodate cultural and social contexts.

Cultural dynamics influencing decision-making during the COVID-19 pandemic: the Italian case

The COVID-19 pandemic has brought about significant changes to the life of most individuals, worldwide. This study explores the cultural factors influencing decision-making during the pandemic, and is part of the CORNER Project, funded by the Research Council of Norway, aimed at understanding institutional response in the early phases of the Covid-19 emergency in Norway, Sweden, and Italy. Semi-structured interviews with key political-administrative leaders in Italy (N = 35) were conducted and content-analyzed, allowing the identification of the underlying cultural dynamics that played a role in these decisions. Thematic analysis was used to assess the influence of cultural factors on the crisis management and early reaction of institutions and citizens to the spread of Covid. In line with previous studies, and as expected, the individualism vs. collectivism dimension can explain differential health outcomes during the outbreak. In this paper we argue that individualism-collectivism cultural values can also play a pivotal role in public compliance with Covid-19 restrictions, and psychological responses during the pandemic.

Veiled to Express: Uncovering the Effect of Mask-Wearing on Voice Behavior in the Workplace

Since the outbreak of COVID-19, mask-wearing has become a widespread phenomenon. Even after the pandemic, people continue to maintain the habit of wearing masks in their daily lives. While existing research has explored how mask-wearing can influence wearers' behavior in everyday life, its effects in the workplace have received less attention. Drawing on self-perception theory, this study examined the positive effect of mask-wearing in the workplace on wearers' voice behavior via psychological safety. An online experiment (N = 291) using a within-subject manipulation of wearing masks supported our hypotheses. This study uncovered the positive psychological and behavioral consequences of mask-wearing beyond its benefits in people's health conditions and everyday life.

Compliance with COVID-19 preventative health measures in the United Kingdom: a latent profile analysis

Governments have adopted unprecedented measures to assist in slowing the spread of the COVID-19 pandemic, but compliance varies among individuals. This UK study uses latent profile analysis to identify four classes of individuals on factors believed to influence compliance. Those who sought health information from authoritative sources and actively sought information from multiple sources were most compliant. Profile differences in compliance and vaccination status were also primarily driven by trust in healthcare institutions over trust in government. These findings contribute to understanding compliance profiles and emphasise the importance of authoritative information and trust in healthcare systems.

Modeling the Relationship Between Perceived Descriptive Norms and Willingness to Practice COVID-19 Preventative Behaviors: A Test of the Mediation and Moderation Mechanisms in the Theory of Normative Social Behavior

Social norm has been found to impact compliance with COVID-19 preventative behaviors, including handwashing, wearing a face mask, social distancing, and cleaning and disinfecting frequently touched surfaces. There is, however, a limited understanding of the social norm influence mechanisms and its boundary condition in the context of COVID-19. Guided by the theory of normative social behaviors (TNSB), this study conducted an online survey (N = 336) to examine whether perceived injunctive norms (PIN), outcome expectation (OE), group identity (GID), group orientation (GO), and cultural tightness-looseness (CTL) can moderate and/or mediate the relationship between perceived descriptive norms (PDN) and behavioral intentions (BI) to perform COVID-19 preventative behaviors in the United States. Results showed that whereas OE mediated the PDN-BI relationship to enact all four focal behaviors, PIN mediated the PDN-BI relationship for social distancing, wearing a face mask, and cleaning and disinfecting. However, inconsistent with the predictions, all five moderators (i.e. PIN, OE, GO, GID, and CTL) attenuated, instead of strengthening, the PDN-BI relationships for particular preventative behaviors. Theoretical and practical implications were discussed.

Investigating the spatiotemporal characteristics and medical response during the initial COVID-19 epidemic in six Chinese cities

In the future, novel and highly pathogenic viruses may re-emerge, leading to a surge in healthcare demand. It is essential for urban epidemic control to investigate different cities' spatiotemporal spread characteristics and medical carrying capacity during the early stages of COVID-19. This study employed textual analysis, mathematical statistics, and spatial analysis methods to examine the situation in six highly affected Chinese cities. The findings reveal that these cities experienced three phases during the initial outbreak of COVID-19: "unknown-origin incubation", "Wuhan-related outbreak", and "local exposure outbreak". Cities with a high number of confirmed cases exhibited a multicore pattern, while those with fewer cases displayed a single-core pattern. The cores were distributed hierarchically in the central built-up areas of cities' economic, political, or transportation centers. The radii of these cores shrank as the central built-up area's level decreased, indicating a hierarchical decay and a core-edge structure. It suggests that decentralized built environments (non-clustered economies and populations) are less likely to facilitate large-scale epidemic clusters. Additionally, the deployment of designated hospitals in these cities was consistent with the spatial distribution of the epidemic; however, their carrying capacity requires urgent improvement. Ultimately, the essence of prevention and control is the governance of human activities and the efficient management of limited resources about individuals, places, and materials through leveraging IT and GIS technologies to address supply-demand contradictions.

The role of collectivism, liberty, COVID fatigue, and fatalism in public support for the zero-COVID policy and relaxing restrictions in China

BACKGROUND

China was the last country in the world to relax COVID-19 restrictions. A successful public health policy requires public support. This analysis examined the factors associated with Chinese support for zero-COVID and relaxing COVID-19 restrictions in China.

METHOD

Two online surveys were conducted among Chinese participants in mainland China on June 10-13 (N = 460) and December 2, 2022 (N = 450). These two samples were similar based on the participants' demographics.

RESULTS

The results revealed that the perceived health consequences of a COVID-19 policy, perceived norms of approving a COVID-19 policy, and hope positively predicted the participants' support for the COVID-19 policy. The results further showed that collectivism and fatalism positively predicted support for zero-COVID and negatively predicted support for relaxing restrictions. COVID fatigue was negatively associated with support for zero-COVID and positively associated with support for relaxing restrictions. Liberty positively predicted support for relaxing restrictions in June and negatively predicted zero-COVID in December 2023. It did not positively or negatively predict support for the policy adopted by the government.

CONCLUSION

Collectivism, liberty, COVID fatigue, and fatalistic beliefs are important considerations connected to public support for a COVID-19 policy. The role of liberty was more nuanced and depended on the survey's time and whether the government adopted the policy.

An Evaluation of Messages to Promote Parental Intent to Vaccinate Children Aged <12 Years Against COVID-19

OBJECTIVES

Effective health communication can increase intent to vaccinate. We compared 8 messages that may influence parents' intent to vaccinate their children against COVID-19.

METHODS

In a cross-sectional survey of adults in the United States administered online in August 2021, 1837 parents and legal guardians were exposed to 8 messages (individual choice, gain/practical benefits, nonexpert, health care provider recommendation, altruism/community good, safety/effectiveness, safety, and effectiveness) to determine message reception and influence on intent to vaccinate their children. Parents responded to 10 questions using a Likert scale. We computed odds ratios (ORs) for each message, with an OR >1.0 indicating greater observed odds of participant agreement with the follow-up statement as compared with a reference message. We compared outcomes individually across messages with ordinal logistic regression fit using generalized estimating equations.

RESULTS

The individual choice message had the highest odds of agreement for understanding intent (OR = 2.10; 95% CI, 1.94-2.27), followed by the health care provider recommendation message (OR = 1.58; 95% CI, 1.46-1.71). The individual choice message had the highest odds of memorability, relatability, and trustworthiness. The altruism/community good message was at or near second best. The altruism/community good message had the highest or near-highest odds of increasing parents' intent to vaccinate their children, asking friends and family for their thoughts, and searching for additional information. The message that most motivated parents to vaccinate their children depended on parental intent to vaccinate prior to being exposed to the tested messages.

CONCLUSIONS

Messages with themes of individual choice, health care provider recommendation, and altruism/community good may be used in future message campaigns. Further research is needed to refine message concepts related to altruism/community good.

Coping during COVID-19: how attitudinal, efficacy, and personality differences drive adherence to protective measures

INTRODUCTION

COVID-19 has had a devastating impact on people's lives since its initial outbreak and global spread in 2020. While the U.S. government and public health officials have recommended best practices such as social distancing, wearing a mask, and avoiding large public gatherings, these orders have been met with varying levels of acceptance from the public. Given the disparate compliance, this study builds on Social Cognitive Theory (SCT) to explore individual differences and personal motivation factors in order to better understand what may influence one's likelihood to adhere to COVID-19 protective measures.

METHODS

A U.S. national survey (N = 2,049) was conducted April-May 2020, roughly one month after stay-at-home orders were issued in some states. Participants were asked to report their likelihood of taking individual and community protective measures. Multivariate hierarchical linear regressions were run to analyze the extent to which participants' concerns about COVID-19's impact, individual and collective self-efficacy, coping behaviors, and personality traits influenced the dependent variables.

RESULTS

Findings showed that COVID-19-related health concerns, collective efficacy, and proactive coping strategies were positively related to participants' likelihood of taking protective measures. Those with greater concerns about their general well-being and the economy, adverse coping strategies like denial and joking, as well as sensation-seeking personalities, were less likely to take protective measures.

CONCLUSION

The discussion considers how individual differences fit into broader global efforts to stem COVID-19. Practical implications for public health messaging are that communication may focus on facilitating efficacy in order to boost compliance with protective measures.

Prosociality predicts changes in leisure activities during the COVID-19 pandemic

Several studies suggest that leisure activities enhance well-being. In line with this perspective, a recent study indicates that augmenting indoor leisure activities to compensate for diminished outdoor pursuits could sustain or enhance well-being during the COVID-19 pandemic. The present study was designed to identify personality traits that predict such behavioral shifts in indoor versus outdoor leisure activities during the pandemic. The present study included 657 participants (Mage = 41.08) and measured 12 personality traits that a previous study reported were associated with health-protective behaviors during COVID-19. Our findings indicate that the rise in indoor leisure activities correlated with prosocial tendencies toward family and friends/acquaintances (but not strangers), self-centered interest, resilience, and Big Five personality traits. Conversely, the decline in outdoor activities was linked solely to prosociality toward family and friends/acquaintances. Further interaction analysis uncovered that prosocial tendencies toward close relations predicted increased indoor activities as an alternative to outdoor engagements. We concluded that prosociality promoted behavioral changes that significantly prevented infections in intimate others, and it could maintain personal well-being during the COVID-19 pandemic by facilitating behavior change.

Exploring the Barriers and Facilitators of Mask-Wearing Behavior During the COVID-19 Pandemic in Taiwan, the United States, the Netherlands, and Haiti: A Qualitative Study

OBJECTIVE

This study explored the barriers and facilitators of mask-wearing behaviors during the pandemic in Taiwan, the United States, the Netherlands, and Haiti.

METHODS

Face-to-face interviews were conducted in Taiwan and online interviews were conducted with participants in the United States, the Netherlands, and Haiti.

RESULTS

In general, the habit of wearing a mask before coronavirus disease 2019 (COVID-19) was reported by Taiwanese participants. Additionally, Taiwanese participants perceived that wearing a mask was a social responsibility during the pandemic, suggesting that the collectivistic context might influence mask-wearing behavior. Unlike the Taiwanese population, some people in the United States and the Netherlands were reluctant to wear masks due to perceived restrictions on their freedom. Participants from Haiti mentioned that people who wore masks encountered violence, bullying, and discrimination. The results of this study suggest that political leadership and mask mandates have a strong impact on people's mask-wearing behavior.

CONCLUSIONS

These findings have valuable implications for the design of diverse behavioral interventions to enhance mask-wearing as part of infectious disease preparedness. Additionally, the findings from these countries offer valuable insights for the development of effective public health interventions to enhance society's resilience during the current pandemic and future infectious disease outbreaks.

The paradox of pandemic mitigation? Moderating role of pandemic severity on the impact of social distancing policies: a cultural value perspective

BACKGROUND

Social distancing policies were of utmost importance during the early stages of the COVID-19 pandemic. These policies aimed to mitigate the severity of local outbreaks by altering public behavior. However, if the severity of the pandemic reduces, the impact of these policies on actual behavior may decrease. This study aims to examine, from a global perspective, whether the impact of social distancing policies on actual mobility is moderated by local pandemic severity and whether this moderating effect varies across cultural value contexts.

METHODS

We combined multiple publicly available global datasets for structural equation model analysis. 17,513 rows of data from 57 countries included in all databases were analyzed. Multilevel moderated moderation models were constructed to test the hypotheses.

RESULTS

More stringent policies in a region mean less regional mobility (β = -0.572, p < 0.001). However, the severity of local outbreaks negatively moderated this effect (β = -0.114, p < 0.001). When the pandemic was not severe, the influence of policy intensity on mobility weakened. Furthermore, based on Schwartz's cultural values theory, cultural values of autonomy (β = -0.109, p = 0.011), and egalitarianism (β = -0.108, p = 0.019) reinforced the moderating effect of pandemic severity. On the other hand, cultural values of embeddedness (β = 0.119, p = 0.006) and hierarchy (β = 0.096, p = 0.029) attenuated the moderating effect.

CONCLUSIONS

Social distancing policies aim to reduce the severity of local pandemics; however, the findings reveal that mitigating local pandemics may reduce their impact. Future policymakers should be alert to this phenomenon and introduce appropriate incentives to respond. The results also show that the moderating role of pandemic severity varies across cultures. When policies are promoted to deal with global crises, policymakers must seriously consider the resistance and potential incentives of cultural values.

Health Behavior and Attitudes During the COVID-19 Pandemic Among Vulnerable and Underserved Latinx in the Southwest USA

The COVID-19 pandemic highlighted deep-rooted health disparities, particularly among Latinx immigrants living on the Mexico-US border. This article investigates differences between populations and adherence to COVID-19 preventive measures. This study investigated whether there are differences between Latinx recent immigrants, non-Latinx Whites, and English-speaking Latinx in their attitudes and adherence to COVID-19 preventive measures. Data came from 302 participants who received a free COVID-19 test at one of the project sites between March and July 2021. Participants lived in communities with poorer access to COVID-19 testing. Choosing to complete the baseline survey in Spanish was a proxy for being a recent immigrant. Survey measures included the PhenX Toolkit, COVID-19 mitigating behaviors, attitudes toward COVID-19 risk behaviors and mask wearing, and economic challenges during the COVID-19 pandemic. With multiple imputation, ordinary least squares (OLS) regression was used to analyze between-group differences in mitigating attitudes and behaviors toward COVID-19 risk. Adjusted OLS regression analyses showed that Latinx surveyed in Spanish perceived COVID-19 risk behaviors as more unsafe (b = 0.38, p = .001) and had stronger positive attitudes toward mask wearing (b = 0.58, p = .016), as compared to non-Latinx Whites. No significant differences emerged between Latinx surveyed in English and non-Latinx Whites (p > .05). Despite facing major structural, economic, and systemic disadvantages, recent Latinx immigrants showed more positive attitudes toward public health COVID-19 mitigating measures than other groups. The findings have implications for future prevention research about community resilience, practice, and policy.

Cultural Psychology: Beyond East and West

Research in cultural psychology over the last three decades has revealed the profound influence of culture on cognitive, emotional, and motivational processes shaping individuals into active agents. This article aims to show cultural psychology's promise in three key steps. First, we review four notable cultural dimensions believed to underlie cultural variations: independent versus interdependent self, individualism versus collectivism, tightness versus looseness of social norms, and relational mobility. Second, we examine how ecology and geography shape human activities and give rise to organized systems of cultural practices and meanings, called eco-cultural complexes. In turn, the eco-cultural complex of each zone is instrumental in shaping a wide range of psychological processes, revealing a psychological diversity that extends beyond the scope of the current East-West literature. Finally, we examine some of the non-Western cultural zones present today, including Arab, East Asian, Latin American, and South Asian zones, and discuss how they may have contributed, to varying degrees, to the formation of the contemporary Western cultural zone.

Daily positive and negative affect during the COVID-19 pandemic

The COVID-19 pandemic influenced emotional experiences globally. We examined daily positive and negative affect between May/June 2020 and February 2021 (N = 151,049; 3,509,982 observations) using a convenience sample from a national mobile application-based survey that asked for daily affect reports. Four questions were examined: (1) How did people in the United States feel from May/June 2020 to February 2021?; (2) What demographic variables are related to positive and negative affect?; (3) What is the relationship between experienced stressors and daily affect?; and (4) What is the relationship between daily affect and preventive behavior? Positive affect increased, and negative decreased over time. Demographic differences mirrored those from before the pandemic (e.g., younger participants reported more negative and less positive affect). Stressors such as feeling unwell, experiencing COVID-19 symptoms, exposure to COVID-19, and lack of sleep were associated with less positive and more negative affect. Exercising protective behaviors predicted future affect, and affect also predicted future protective behaviors (e.g., less protective behavior when happy but more when grateful and thoughtful). The implications for public health communication were discussed.

Latent profile and network analysis of risk perception among a sample of Chinese university students during the COVID-19 pandemic: a cross-sectional and longitudinal study

Background

The risk perception of contracting COVID-19 is an important topic for assessing and predicting COVID-19 infection and health education during the pandemic. However, studies that use latent profiles and network analysis together to measure the risk perception of COVID-19 are rare. Therefore, this study combined latent profile analysis and network analysis to measure risk perception toward COVID-19 among Chinese university students through a cross-sectional and longitudinal study.

Methods

A sample of 1,837 Chinese university students (735 males, 40%) completed the cross-sectional study with an eight-item risk perception questionnaire in January 2020, while 334 Chinese university students (111 males, 33.2%) completed the longitudinal study at three time points.

Results

A two-class model including a low risk perception class (n = 1,005, 54.7%) and a high risk perception class (n = 832, 45.3%) was selected for the cross-sectional study. Nodes rp6 ("Average people have chances of contracting COVID-19'') and rp7 ("Average people worry about catching COVID-19") had the strongest edge intensity (r = 0.491), while node rp5 ("The COVID-19 outbreak affects the whole country") had the highest strength centrality in the cross-sectional study. The risk perception of contracting COVID-19 decreased continuously at the three time points. Moreover, the network structures and global strengths had no significant differences in the longitudinal study.

Conclusions

The risk perception of contracting COVID-19 decreased continually during the COVID-19 pandemic, which indicated the importance of cultural influence and effective government management in China. In addition, university students displayed strong trust and confidence in the government's ability to fight COVID-19. The results indicate that the government should take strong measures to prevent and intervene in various risks and reinforce the public's trust through positive media communications.

Collectivist culture, environmental regulation and pollution emissions: evidence from China

Collectivist culture serves as a significant cultural foundation in China. It could, to some extent, shape public attitudes toward the environment and thus influence the implementation of related policies. To examine this hypothesis, this study constructs the collectivist culture intensity index for 25 Chinese provinces spanning from 2010 to 2020. Through a fixed-effect model, we explore how the collectivist culture intensity affects pollution emissions in China. The empirical results indicate the significance of collectivism in enhancing emission reduction through environmental regulations. This conclusion remains robust even when excluding the impact of endogeneity concerns by adopting the instrumental variable approach. Heterogeneity analysis shows that collectivism is more effective in enhancing market-based environmental regulations rather than those driven by policies. Further mechanism analysis confirms that green innovation is a crucial pathway through which collectivism influences pollution emissions. These findings here will offer guidance to policymakers when formulating environmental policies for contexts with different regional cultures.

A synthesis of evidence for policy from behavioural science during COVID-19

Scientific evidence regularly guides policy decisions1, with behavioural science increasingly part of this process2. In April 2020, an influential paper3 proposed 19 policy recommendations ('claims') detailing how evidence from behavioural science could contribute to efforts to reduce impacts and end the COVID-19 pandemic. Here we assess 747 pandemic-related research articles that empirically investigated those claims. We report the scale of evidence and whether evidence supports them to indicate applicability for policymaking. Two independent teams, involving 72 reviewers, found evidence for 18 of 19 claims, with both teams finding evidence supporting 16 (89%) of those 18 claims. The strongest evidence supported claims that anticipated culture, polarization and misinformation would be associated with policy effectiveness. Claims suggesting trusted leaders and positive social norms increased adherence to behavioural interventions also had strong empirical support, as did appealing to social consensus or bipartisan agreement. Targeted language in messaging yielded mixed effects and there were no effects for highlighting individual benefits or protecting others. No available evidence existed to assess any distinct differences in effects between using the terms 'physical distancing' and 'social distancing'. Analysis of 463 papers containing data showed generally large samples; 418 involved human participants with a mean of 16,848 (median of 1,699). That statistical power underscored improved suitability of behavioural science research for informing policy decisions. Furthermore, by implementing a standardized approach to evidence selection and synthesis, we amplify broader implications for advancing scientific evidence in policy formulation and prioritization.

Looking beyond vaccines: Cultural tightness-looseness moderates the relationship between immunization coverage and disease prevention vigilance

Advancements in vaccination technologies mitigate disease transmission risks but may inadvertently suppress the behavioral immune system, an evolved disease avoidance mechanism. Applying behavioral immune system theory and utilizing robust big data analytics, we examined associations between rising vaccination coverage and government policies, public mobility, and online information seeking regarding disease precautions. We tested whether cultural tightness-looseness moderates the relationship between mass immunization and disease prevention vigilance. Comprehensive time series analyses were conducted using American data (Study 1) and international data (Study 2), employing transfer function modeling, cross-correlation function analysis, and meta-regression analysis. Across both the US and global analyses, as vaccination rates rose over time, government COVID-19 restrictions significantly relaxed, community mobility increased, and online searches for prevention information declined. The relationship between higher vaccination rates and lower disease prevention vigilance was stronger in culturally looser contexts. Results provide initial evidence that mass immunization may be associated with attenuated sensitivity and enhanced flexibility of disease avoidance psychology and actions. However, cultural tightness-looseness significantly moderates this relationship, with tighter cultures displaying sustained vigilance amidst immunization upticks. These findings offer valuable perspectives to inform nuanced policymaking and public health strategies that balance prudent precautions against undue alarm when expanding vaccine coverage worldwide.

Country's value priorities in health crisis: How dominant societal motivations shape COVID-19 severity

This paper presents two comprehensive studies examining how Schwartz's human values dimensions at the country level predict COVID-19 pandemic severity. Study 1 aggregated survey data across 89 countries from the European Social Survey and World Values Survey to assess societal-level conservation versus openness to change (CON-OTC) and self-enhancement versus self-transcendence (SE-ST) value-continuums. Study 2 developed an innovative archival measurement approach using 10 indicators to estimate these value dimensions for over 180 countries. Both studies employed multilevel modeling to test the relationships between country-level values and COVID-19 severity, measured through epidemiological indicators of transmission speed, case fatality rate, infection prevalence and mortality burden. Results revealed that the CON-OTC and SE-ST value-continuums showed consistent, significant negative associations with transmission speed and infection prevalence before adjusting for modernization, latitude, historical pathogen prevalence and government stringency across both studies. However, after accounting for these socioecological and policy covariates, the CON-OTC value-continuum positively predicted case fatality rate in both studies, implying conservation values could increase COVID-19 lethality. In contrast, across both studies, the SE-ST value-continuum negatively predicted case fatality rate after adjusting for the covariates, suggesting countries prioritizing self-enhancement values exhibited relatively lower pandemic severity and lethality when accounting for developmental, ecological, and policy factors. Accordingly, the studies advance theoretical understanding of how country's value priorities shape COVID-19 impact. Methodologically, these studies contribute through multilevel techniques that account for spatial dependencies, as well as an innovative ecological measurement. Overall, this research demonstrates the value of applying Schwartz's framework at a societal level to predict global health crises and pandemics.

People in Tight Cultures and Tight Situations Wear Masks More: Evidence From Three Large-Scale Studies in China

Studies have found large differences in masks use during the pandemic. We found evidence that cultural tightness explains mask use differences and this association was more robust in tight situations like subways. In Study 1, we observed 23,551 people's actual mask use in public places around China. People wore masks more in tight situations; however, differences did not extend to outdoor streets and public parks, where norms are looser. We replicated this finding using a data from 15,985 people across China. Finally, in a preregistered study we observed mask use with the removal of COVID-19 restrictions, people still wore masks more in tight situations like subways than in loose situations of parks. These findings suggest that norm tightness has a lasting association with people's health-protective behaviors, especially in tight situations. It provides insight into how different cultures might respond with future pandemics and in what situations people adopt health-protective behaviors.

Habitual Mask Wearing as Part of COVID-19 Control in Japan: An Assessment Using the Self-Report Habit Index

Although the Japanese government removed mask-wearing requirements in 2023, relatively high rates of mask wearing have continued in Japan. We aimed to assess psychological reasons and the strength of habitual mask wearing in Japan. An Internet-based cross-sectional survey was conducted with non-random participant recruitment. We explored the frequency of mask usage, investigating psychological reasons for wearing masks. A regression analysis examined the association between psychological reasons and the frequency of mask wearing. The habitual use of masks was assessed in the participant's most frequently visited indoor space and public transport using the self-report habit index. The principal component analysis with varimax rotation revealed distinct habitual characteristics. Among the 2640 participants surveyed from 6 to 9 February 2023, only 4.9% reported not wearing masks at all. Conformity to social norms was the most important reason for masks. Participants exhibited a slightly higher degree of habituation towards mask wearing on public transport compared to indoor spaces. The mask-wearing rate was higher in females than in males, and no significant difference was identified by age group. Daily mask wearing in indoor spaces was characterized by two traits (automaticity and behavioral frequency). A high mask-wearing frequency has been maintained in Japan during the social reopening transition period. Mask wearing has become a part of daily habit, especially on public transport, largely driven by automatic and frequent practice.

Individualistic powerfulness and collectivistic powerlessness corrupts: how power and cultural orientation influence corruption

Evidence from individualistic cultures suggests that power corrupts. Using a goals-based perspective, here we argue that power and culture jointly predict corrupt attitudes and behavior. Four studies (N = 447) and one meta-analysis were conducted to test these hypotheses. Study 1 investigated the joint effects of power and individuals' cultural orientations on corruption proclivity. Studies 2 and 3 assessed if power and cultural orientations affect actual corrupt behaviors (i.e. abuse of discretion in Study 2 and bribe-taking in Study 3). Study 4 tested the hypothesis at a national level, using monocultural samples both in the UK and China. The results consistently showed that the effects of power on corruption depend on culture: for collectivistic individual orientations and cultures, holding power predicts less corruption than lacking power; in contrast, holding power predicts more corruption for individualist orientations and cultures. Our findings represent the first direct experimental and correlational evidence regarding the links between power, culture, and corruption.

Policy stringency and the spread of COVID-19: The moderating role of culture and its implications on first responses

There has been a noticeable variance between countries in the growth rate of COVID-19 since the start of the pandemic. Researchers attempted to understand this variance from two primary perspectives: the policies implemented to curb the spread of the virus [1] and the cross-country cultural differences [2]. However, little research to date has looked at the joint effects of policy responses and national culture. We argue that the effectiveness of restrictive policies depends on cultural values. Specifically, when policies are non-mandatary, cultural values influence people's voluntary adherence to these policies, and hence, the spread of COVID-19. We analyzed the growth data in daily new cases across 78 countries, focusing on the joint impact of containment policies and cultural values. We found that although policy responses (i.e., containment policies) significantly predicted the spread rate of COVID-19 over time, their effects were moderated by cultural variables as well. Implications for policymaking are discussed.

How Rice Fights Pandemics: Nature-Crop-Human Interactions Shaped COVID-19 Outcomes

Wealthy nations led health preparedness rankings in 2019, yet many poor nations controlled COVID-19 better. We argue that a history of rice farming explains why some societies did better. We outline how traditional rice farming led to tight social norms and low-mobility social networks. These social structures helped coordinate societies against COVID-19. Study 1 compares rice- and wheat-farming prefectures within China. Comparing within China allows for controlled comparisons of regions with the same national government, language family, and other potential confounds. Study 2 tests whether the findings generalize to cultures globally. The data show rice-farming nations have tighter social norms and less-mobile relationships, which predict better COVID outcomes. Rice-farming nations suffered just 3% of the COVID deaths of nonrice nations. These findings suggest that long-run cultural differences influence how rice societies-with over 50% of the world's population-controlled COVID-19. The culture was critical, yet the preparedness rankings mostly ignored it.

The Differential Experience of COVID-19 on Asian American Subgroups: The Los Angeles Pandemic Surveillance Cohort Study

Data from Asian Americans (AsA) are commonly aggregated in research studies and reporting, obscuring the significant differences across AsA subgroups. We investigated the differential experience of AsA subgroups in COVID-19 testing, vaccination, engagement in risky and protective behaviors and mental health status against this infectious disease. We surveyed a representative sample of the Los Angeles County population (N = 5500) in April 2021 as part of the Los Angeles Pandemic Surveillance Cohort Study and focused on participants who self-identified as AsA (N = 756). There were significant differences across the AsA subgroups, with Koreans, Asian Indians, and Other Asians living in areas with higher COVID-19 mortality rates, and Asian Indians demonstrating the lowest proportion of COVID-19 vaccination. Vietnamese and Koreans had a higher proportion of becoming unemployed during the pandemic. Although the AsA sample on average demonstrated better outcomes than other racial and ethnic groups, the apparent advantages were heterogenous and due to specific subgroups of AsAs rather than AsAs as a whole. The observed differences in COVID-19 measures across AsA subgroups underscore the need to disaggregate AsA data to identify and reduce existing disparities.

Cultural differences in humor: A systematic review and critique

Humor is universal but also culturally nuanced. This review (including 31 empirical articles in English) systematically examines cultural differences in humor perception and use. Most notably, North Americans tend to perceive humor more positively, rate themselves as more humorous, and use humor more than East Asians. Moreover, this review highlights complex cultural differences in the use of four humor styles (affiliative, self-enhancing, aggressive, and self-defeating). Finally, I discuss limitations of the cross-cultural literature on humor and propose future research directions. Theoretically, more studies should move beyond comparing East Asian and North American cultures, examine the consequences of cultural differences in humor, and track changes in humor perception and use over time. Methodologically, more studies should employ experiments to strengthen causality, recruit larger and more representative samples, and preregister theory-driven hypotheses.

Individualism-Collectivism and COVID-19 Prevention Behaviors in Young Adults: The Indirect Effects of Psychological Distress and Pandemic Fears

Stemming on the theoretical framework of individualism-collectivism, this study aims to interpret COVID-19 prevention behaviors in young adults in the light of cultural orientations, hypothesizing the mediating role of two pandemic affects (i.e., fear for COVID-19 consequences and psychological distress during pandemic). Participants were 296 young adults living in Italy (Mage = 23.96, SDage = 3.04; 79.7% women), who completed an online anonymous survey. Data were gathered from December 2020 to May 2021. A path analysis model explored direct and indirect relationships among study variables. Psychological distress significantly reduced the compliance with prevention measures, whereas pandemic fears increased it. The collectivistic orientations (Vertical Collectivism and Horizontal Collectivism) positively predicted prevention behaviors via increasing pandemic fears. The egalitarian dimensions (Horizontal Individualism and Horizontal Collectivism) were positive predictors of compliance via reducing psychological distress during pandemic. Finally, Vertical Individualism was a risk factor that negatively predicted prevention behaviors both directly and indirectly, via increasing psychological distress. The results provide new insights into the emotional mechanisms that link individualism and collectivism orientations to COVID-19 prevention behaviors, with interesting implications for public health policies, prevention, and future research.

Beyond the surface: accounting for confounders in understanding the link between collectivism and COVID-19 pandemic in the United States

According to the parasite-stress theory, collectivism serves as a trait of ingroup assortative sociality, providing defense against infectious diseases. This study investigated the association between cultural collectivism and COVID-19 severity at the state (Study 1: N = 51), county (Study 2: N = 3,133), and daily (Study 3: N = 52,806) levels from the beginning of 2020 to the end of 2022. State-level collectivism was assessed using two distinct measures: the U.S. collectivism index, focusing on social interconnectedness and interdependence, and the subjective-culture individualism-collectivism index (reversed), capturing attitudes and beliefs related to religion, abortion, and same-sex marriage. By employing random-intercept multilevel models, the results demonstrated significant and negative effects of state-level collectivism, as measured by the U.S collectivism index, on COVID-19 cases per million, COVID-19 deaths per million, and composite COVID-19 severity index, after controlling for confounding factors, such as socioeconomic development, ecological threats, disease protective behaviors, cultural norms, and political influences. A mini meta-analysis (Study 4: N = 9) confirmed the significance of these effects across studies. These findings supported the proactive role of collectivism in defending against the novel coronavirus in the United States, aligning with the parasite-stress theory of sociality. However, the subjective-culture individualism-collectivism index (reversed) did not exhibit a significant relationship with COVID-19 severity when confounding factors were considered. The high correlation between the subjective-culture individualism-collectivism index (reversed) and the controlled variables suggested shared variance that could diminish its impact on COVID-19 outcomes. Accordingly, the present findings underscore the significance of accounting for confounding factors when examining the association between collectivism and COVID-19 severity at population level. By considering relevant confounding factors, researchers could gain a comprehensive understanding of the complex interplay between cultural collectivism and its influence on COVID-19 severity. Overall, this research contributes to our understanding of how cultural collectivism shapes the COVID-19 pandemic in the United States, emphasizing the importance of adjusting for confounding effects in population level studies.

Cultural differences in explicit and implicit support provision and underlying motivations for self-esteem, closeness, and relational concerns

This research explores how culture influences the motivations underlying explicit (emotional and instrumental) and implicit (companionship and attentiveness) support provision. Two studies (N = 1,106) compared the responses of European Americans and Japanese individuals to a close other's stressful event. The results showed that European Americans were more likely than Japanese to provide explicit support and more motivated to increase the close other's self-esteem and feeling of closeness. Conversely, Japanese individuals were more likely to provide attentiveness support, motivated by concern for an entire group and a friend. These findings support the motivation as a mediator hypothesis. On the other hand, the culture as a moderator hypothesis applied to the association between concern for an entire group motivation and implicit support provision. Specifically, concern for an entire group motivation predicted companionship support provision only in Japanese, while it predicted attentiveness support provision mainly in European Americans.

Gender bias in cultural tightness across the 50 US states, its correlates, and links to gender inequality in leadership and innovation

Cultural tightness theory, which holds that "tight" cultures have rigid norms and sanctions, provides unique insights into cultural variations. However, current theorizing has not analyzed gender differences in cultural tightness. Addressing this gap, this research shows that women are more constrained than men by norms within the same society. By recruiting 15,425 respondents, we mapped state-level gender bias in cultural tightness across the United States. Variability in gender bias in cultural tightness was associated with state-level sociopolitical factors (religion and political ideology) and gender-related threats. Gender bias in cultural tightness was positively associated with state-level gender inequality in (business and political) leadership and innovation, two major challenges faced by women professionals. Overall, this research advances cultural tightness theory and offers a cultural norms account on persistent gender inequalities in society.

I belong, therefore I am: The role of economic culture in compliance with COVID-19 preventive measures

Cultural orientations in relation to individualism and collectivism produced by subsistence strategies can lead to a wide array of consequences for perception, cognition, and emotion. We predict that, as a result of different economic patterns, farmers with greater collectivism would show more compliance with COVID-19 precautionary behavior than herders with greater individualism. By adopting a "just minimal difference" approach, we compared Chinese farming and herding communities that share a national identity, ethnicity, and residential area but vary in their degree of individualism-collectivism. Consistent with our hypothesis, Study 1 found that farmers reported higher compliance with prevention initiatives than herders in self-report survey. Study 2 provided a behavioral choice confirmation of the observed relationship. The present research provides the empirical evidence that economic activities can have divergent effects on mitigation strategies in the COVID-19 fight, and these results have meaningful implications for socioecological psychology theory and for pandemic prevention and control.

Correlates of COVID-19 Preventative Behaviors before and after Vaccination Availability

As the COVID-19 pandemic progressed, various preventative behaviors and eventually vaccinations became available to decrease the spread of the virus. The current study examined a variety of variables (i.e., age, COVID-19-related economic hardship, interpersonal concern, personality, fear of COVID-19, normative beliefs, political beliefs, and vaccine hesitancy) to better understand predictors of preventative behaviors and vaccination status at different points throughout the pandemic. Online questionnaires, administered through Qualtrics, were used to collect data using two convenience samples. One was a small sample (N = 44) of non-student participants before the vaccine was readily available. The other sample (N = 274) included college student participants and occurred after the vaccine had been available to all participants. Results suggest that several variables (i.e., fear of COVID-19, normative beliefs, interpersonal concern, and openness) were consistent predictors of public health behaviors at both points in time and across differently aged samples. Other variables (i.e., agreeableness, extraversion, conscientiousness, and economic hardship) were less consistent with their relationships with public health behaviors. Implications related to both research and public health are discussed.

Face mask is an efficient tool to fight the Covid-19 pandemic and some factors increase the probability of its adoption

This study examines the dynamic impact of face mask use on both infected cases and fatalities at a global scale by using a rich set of panel data econometrics. An increase of 100% of the proportion of people declaring wearing a mask (multiply by two) over the studied period lead to a reduction of around 12 and 13.5% of the number of Covid-19 infected cases (per capita) after 7 and 14 days respectively. The delay of action varies from around 7 days to 28 days concerning infected cases but is more longer concerning fatalities. Our results hold when using the rigorous controlling approach. We also document the increasing adoption of mask use over time and the drivers of mask adoption. In addition, population density and pollution levels are significant determinants of heterogeneity regarding mask adoption across countries, while altruism, trust in government and demographics are not. However, individualism index is negatively correlated with mask adoption. Finally, strict government policies against Covid-19 have a strong significant effect on mask use.

Coronavirus-Related Searches on the Internet Predict COVID-19 Vaccination Rates in the Real World: A Behavioral Immune System Perspective

According to the smoke detector and functional flexibility principles of human behavioral immune system (BIS), the exposure to COVID-19 cues could motivate vaccine uptake. Using the tool of Google Trends, we tested that coronavirus-related searches-which assessed natural exposure to COVID-19 cues-would positively predict actual vaccination rates. As expected, coronavirus-related searches positively and significantly predicted vaccination rates in the United States (Study 1a) and across the globe (Study 2a) after accounting for a range of covariates. The stationary time series analyses with covariates and autocorrelation structure of the dependent variable confirmed that more coronavirus-related searches compared with last week indicated increases in vaccination rates compared with last week in the United States (Study 1b) and across the globe (Study 2b). With real-time web search data, psychological scientists could test their research questions in real-life settings and at a large scale to expand the ecological validity and generalizability of the findings.

When Interdependence Backfires: The Coronavirus Infected Three Times More People in Rice-Farming Areas During Chinese New Year

Interdependent cultures around the world have generally controlled COVID-19 better. We tested this pattern in China based on the rice theory, which argues that historically rice-farming regions of China are more interdependent than wheat-farming areas. Unlike earlier findings, rice-farming areas suffered more COVID-19 cases in the early days of the outbreak. We suspected this happened because the outbreak fell on Chinese New Year, and people in rice areas felt more pressure to visit family and friends. We found historical evidence that people in rice areas visit more family and friends for Chinese New Year than people in wheat areas. In 2020, rice areas also saw more New Year travel. Regional differences in social visits were correlated with COVID-19 spread. These results reveal an exception to the general idea that interdependent culture helps cultures contain COVID-19. When relational duties conflict with public health, interdependence can lead to more spread of disease.

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.

Public Support for COVID-19 Responses: Cultural Cognition, Risk Perception, and Emotions

As one of the biggest challenges facing mankind in recent history, the COVID-19 pandemic has had profound impact on the United States. However, government responses ranging from stay-at-home orders to temporary closing of nonessential businesses are not palatable for everyone. This study examines how cultural cognition, risk perception, and discrete emotions influence Americans' support for COVID-19 responses. We found that compared to communitarians and egalitarians, individualists and hierarchists were less likely to support COVID-19 responses. In addition, fear and anger mediated the relationship between risk perception and public support in the opposite direction. The highlight of this study is the moderating role of cultural cognition. Specifically, individualistic worldviews significantly moderated anger's mediation effect on the relationship between risk perception and support for COVID-19 responses.

How National Culture Influences the Speed of COVID-19 Spread: Three Cross-Cultural Studies

The COVID-19 pandemic has affected 222 countries and territories around the globe. Notably, the speed of COVID-19 spread varies significantly across countries. This cross-cultural research proposes and empirically examines how national culture influences the speed of COVID-19 spread in three studies. Study 1 examines the effects of Hofstede's national cultural dimensions on the speed of COVID-19 spread in 60 countries. Drawing on the GLOBE study (House et al., 2004), Study 2 investigates how GLOBE cultural dimensions relate to the speed of the pandemic's spread in 55 countries. Study 3 examines the effect of cultural tightness in 31 countries. We find that five national cultural dimensions - power distance, uncertainty avoidance, humane orientation, in-group collectivism, and cultural tightness - are significantly related to the speed of COVID-19 spread in the initial stages, but not in the later stages, of the pandemic. Study 1 shows that the coronavirus spreads faster in countries with small power distance and strong uncertainty avoidance. Study 2 supports these findings and further reveals that countries with low humane orientation and high in-group collectivism report a faster spread of the disease. Lastly, Study 3 shows that COVID-19 spreads slower in countries with high cultural tightness.

Erroneous Consonance. How inaccurate beliefs about physician opinion influence COVID-19 vaccine hesitancy

Throughout the COVID-19 pandemic, researchers have studied how Americans' attitudes toward health experts influence their health behaviors and policy opinions. Fewer, however, consider the potential gap between individual and expert opinion about COVID-19, and how that might shape health attitudes and behavior. This omission is notable, as discrepancies between individual and expert opinion could help explain why some Americans fail to take action to protect themselves and others from the virus. In novel demographically representative surveys of the US adult population (N = 5,482) and primary care physician subpopulations (PCPs; N = 625), we contrast the relationship between: (1) Americans' and (2) PCPs' preferences regarding who ought to be responsible for taking action to combat the spread of COVID-19, as well as (3) Americans' perceptions of PCP preferences ("PCP meta-opinion"). In the aggregate, we find that Americans are far less likely than PCPs to see a role for both private and state actors in taking action to combat COVID-19. Interestingly, though, this disjuncture is not reflected in individual-level PCP meta-opinion; as most Americans think that PCPs share their views on state and private intervention (τ_b = 0.44-0.49). However, this consonance is often erroneous, which we show can have problematic health consequences. Multivariate models suggest that Americans who both see little place for individual responsibility in taking action to stop viral spread and who think that PCPs share those views are significantly less likely to vaccinate against COVID-19. We conclude by discussing the public health benefits of efforts to bring public opinion in line with expert opinion.

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.

Root exudation of carbon and nitrogen compounds varies over the day-night cycle in pea: The role of diurnal changes in internal pools

Rhizodeposition is the export of organic compounds from plant roots to the soil. Carbon allocation towards rhizodeposition has to be balanced with allocation for other physiological functions, which depend on both newly assimilated and stored nonstructural carbohydrate (NSC). To test whether the exudation of primary metabolites scales with plant NSC status, we studied diurnal dynamics of NSC and amino acid (AA) pools and fluxes within the plant and the rhizosphere. These diurnal dynamics were measured in the field and under hydroponic-controlled conditions. Further, C-limiting treatments offered further insight into the regulation of rhizodeposition. The exudation of primary metabolites fluctuated diurnally. The diurnal dynamics of soluble sugars (SS) and AA concentrations in tissues coincided with exudate pool fluctuations in the rhizosphere. SS and AA pools in the rhizosphere increased with NSC and AA pools in the roots. C starvation treatments offset the balance of exudates: AA exudate content in the rhizosphere significantly decreased while SS exudate content remained stable. Our results suggest that rhizodeposition is to some extent controlled by plant C:N status. We propose that SS exudation is less controlled than AA exudation because N assimilation depends on controlled C supply while SS exudation relies to a greater extent on passive diffusion mechanisms.

Beyond collective intelligence: Collective adaptation

We develop a conceptual framework for studying collective adaptation in complex socio-cognitive systems, driven by dynamic interactions of social integration strategies, social environments and problem structures. Going beyond searching for 'intelligent' collectives, we integrate research from different disciplines and outline modelling approaches that can be used to begin answering questions such as why collectives sometimes fail to reach seemingly obvious solutions, how they change their strategies and network structures in response to different problems and how we can anticipate and perhaps change future harmful societal trajectories. We discuss the importance of considering path dependence, lack of optimization and collective myopia to understand the sometimes counterintuitive outcomes of collective adaptation. We call for a transdisciplinary, quantitative and societally useful social science that can help us to understand our rapidly changing and ever more complex societies, avoid collective disasters and reach the full potential of our ability to organize in adaptive collectives.

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.

Public Engagement with Romanian Government Social Media Accounts during the COVID-19 Pandemic

Following international best practice examples, the Romanian government resorted to its social media accounts to disseminate information and unfold an awareness and persuasion campaign to fight the COVID-19 pandemic. The article focuses on the use of the government's YouTube and Facebook accounts to persuade the population to get vaccinated in 2021 via video messages tailored for this purpose. The research quantified the volume of public engagement with the two waves of the persuasive campaign, finding that, while click-based reactions tended to show a positive attitude toward the campaign, the comments mainly denoted frustration, anger, and anxiety on the part of the public. Moreover, the citizens' engagement with the campaign messages was by far lower than the number of subscribers and followers of the analyzed social media accounts. The goal of the COVID-19 public health persuasion campaign was to build support for the governmental policy and minimize the risks of the pandemic while vaccination was being rolled out. The public reaction to the governmental campaign showed that a finer and more adapted approach was necessary. This study offers a qualitative basis for informing health communication strategies of the challenges posed by social media platforms used in crisis times.

Residential mobility predicts COVID-19 and seasonal flu vaccination behaviors in the United States

Aim

Vaccination is one of the most effective strategies to contain the transmission of infectious diseases; however, people's intentions and behavior for vaccination vary across different regions and countries around the world. It is not clear how socioecological factors such as residential mobility influence people's vaccination behaviors for infectious diseases.

Methods

We analyzed public data on residential mobility and vaccination rates for COVID-19 and seasonal flu in the United States and explored how residential mobility in the previous year influenced vaccination rates for COVID-19 and seasonal flu (2011-2018) across 50 states of the US. The data were accessed and analyzed in 2021.

Results

Study 1 demonstrated that collective-level residential mobility predicted COVID-19 vaccination rates across the United States (B = -168.162, 95% CI [-307.097, -29.227], adjusted R ² = 0.091, p = 0.019). Study 2 corroborated this finding by documenting that collective-level residential mobility predicted vaccination rates for seasonal flu from 2011 to 2018 across the United States (B = -0.789, 95% CI = [-1.018, -0.56], adjusted R ² = 0.222, p < 0.001). The link between residential mobility and vaccination behavior was robust after controlling relevant variables, including collectivism, cultural tightness-looseness, and sociodemographic variables.

Conclusions

Our research demonstrated that residential mobility is an important socioecological factor that influences people's vaccination behaviors for COVID-19 and seasonal flu. The results enrich our understanding of the socioecological factors that influence vaccination behaviors and have implications for developing tailored interventions to promote vaccination during pandemics of infectious diseases.

Assessing the role of collectivism and individualism on COVID-19 beliefs and behaviors in the Southeastern United States

America's unique response to the global COVID-19 pandemic has been both criticized and applauded across political and social spectrums. Compared to other developed nations, U.S. incidence and mortality rates were exceptionally high, due in part to inconsistent policies across local, state, and federal agencies regarding preventive behaviors like mask wearing and social distancing. Furthermore, vaccine hesitancy and conspiracy theories around COVID-19 and vaccine safety have proliferated widely, making herd immunity that much more challenging. What factors of the U.S. culture have contributed to the significant impact of the pandemic? Why have we not responded better to the challenges of COVID-19? Or would many people in the U.S. claim that we have responded perfectly well? To explore these questions, we conducted a qualitative and quantitative study of Florida State University faculty, staff, and students. This study measured their perceptions of the pandemic, their behaviors tied to safety and community, and how these practices were tied to beliefs of individualism and collectivism. We found that collectivist orientations were associated with a greater likelihood of wearing masks consistently, severe interruptions of one's social life caused by the pandemic, greater concern for infecting others, and higher levels of trust in medical professionals for behavioral guidelines surrounding the pandemic. These associations largely persist even after adjusting for political affiliation, which we find is also a strong predictor of COVID-19 beliefs and behaviors.
