Social support, perceived risk and the likelihood of COVID-19 testing and vaccination: cross-sectional data from the United Kingdom

Perceived social support and self-stigma as factors of COVID-19 booster vaccination behavior and intention via cognitive coping and emotion regulation among people infected with COVID-19 in Hong Kong

BACKGROUND

It is imperative to promote behavior/intention of taking up booster COVID-19 vaccination (BI-BV) among people who have ever contracted COVID-19 (PECC). The aims were to investigate the prevalence of BI-BV and its associations with perceived social support. Guided by the stress coping theory, we tested mediators between perceived social support and BI-BV via self-stigma, active coping, and maladaptive emotion regulation (rumination and catastrophizing).

METHODS

A random population-based telephone survey was conducted among adult PECC having completed the primary series of COVID-19 vaccination prior to the diagnosis; 230 participants were interviewed from June to August 2022 during the fifth (last) major outbreak in Hong Kong. The associations between the independent variables and BI-BV were tested by logistic regression analysis. A structural equation model (SEM) tested the indirect effects of the latent variables of self-stigma, active coping, and maladaptive emotion regulation between the latent variable of perceived social support and BI-BV.

RESULTS

The prevalence of BI-BV was 62.2%. It was associated with age, marital status, full-time employment, and chronic disease status. The logistic regression analysis found that BI-BV was positively associated with perceived social support (ORc = 1.31, 95% CI: 1.12- 1.54), active coping (ORc = 1.40, 95% CI: 1.10- 1.79), rumination (ORc = 1.75, 95% CI: 1.13- 2.70), and catastrophizing (ORc = 3.12, 95% CI: 1.49- 6.51) and negatively associated with self-stigma (ORc = 0.80, 95% CI: 0.72- 0.88). In the SEM analysis, the positive association between perceived social support and BI-BV was fully mediated: 1) via self-stigma (β = 0.07, 95% CI: 0.03- 0.14), 2) via active coping (β = 0.06, 95% CI: 0.02- 0.12), and 3) via self-stigma and then active coping (β = 0.01, 95% CI: 0.002- 0.04). Two of these indirect paths involved active coping. The indirect paths involving maladaptive emotion regulation were all non-significant.

CONCLUSIONS

Perceived social support was associated with BI-BV, and was mediated via self-stigma, active coping, and serially self-stigma then active coping but not emotion maladaptation. The data supported the stress cognitive coping model in explaining the association between perceived social support and BI-BV. Interventions promoting BI-BV may consider modifying the observed significant factors. Future longitudinal studies are warranted to confirm the findings.

Uptake and hesitancy of the second booster dose of COVID-19 vaccine among the general population in China after the surge period of the COVID-19 pandemic: a large-scale national study

BACKGROUND

Although the second booster dose of COVID-19 vaccines is available, vaccine hesitancy among the public may have peaked due to the surge in infections caused by the Omicron variant. To improve coverage of the second booster dose, it is crucial to investigate the prevalence of vaccine hesitancy among the general population during this period and explore the reasons for this phenomenon.

METHODS

A cross-sectional survey was conducted between January 5 to February 9, 2023. Variables including sociodemographics, mental health, COVID-19 infection status, COVID-19 vaccination status, and vaccine hesitancy were collected. Univariate and multivariate logistic regression analysis were performed to identify factors associated with the hesitancy of the second booster dose of COVID-19 vaccine among the general population.

RESULTS

Among the 10,623 participants, the uptake rate of the second booster dose was 4.3%. Among those who did not receive the second booster dose, 43.6% expressed vaccine hesitancy. The highest hesitancy rate was observed among participants who had not completed primary immunization (71.4%), followed by those with chronic diseases (48.6%) and those aged 60 and above (33.2%). The COVID-19 vaccine hesitancy was higher among females, participants with high incomes, those with a history of COVID-19 infection, those with depressive symptoms and post-traumatic stress disorder, and those with adverse events after COVID-19 vaccination. Conversely, lower hesitancy was observed among students, participants aged 60 and above, those from southern China, and those with higher level of perceived social support.

CONCLUSIONS

COVID-19 vaccine hesitancy remains prevalent among the general population in China after the surge period of the pandemic. Crucial steps, such as raising public awareness of the benefits and potential side effects of regular COVID-19 vaccination, ensuring timely monitoring and disclosure of pandemic information, and implementing targeted measures to improve social support and mental health, should be taken. These efforts will be instrumental in reducing vaccine hesitancy, advancing vaccination campaigns, and effectively preparing for the potential future outbreaks.

Vaccine hesitancy: a structured review from a behavioral perspective (2015-2022)

Vaccine hesitancy, a complex behavioral phenomenon, poses a significant global health threat and has gained renewed attention amidst the COVID-19 pandemic. This paper scrutinized peer-reviewed literature on vaccine hesitancy published from 2015 to 2022, with a specific focus on behavioral perspectives, utilizing a Theories-Constructs-Variables-Contexts-Methods (TCVCM) framework. The study highlighted prominent theoretical approaches, abstract concepts, research variables, global contexts and academic techniques employed across a selected sample of 138 studies. The result is a consolidated overview of research and schematization of the factors influencing vaccine hesitancy and vaccination behaviors. These include individual-level, contextual, vaccine-specific, organizational, and public-policy-related dynamics. The findings corroborated the complexity of vaccine hesitancy and emphasized the difficulties of pursuing vaccine advocacy. The analysis also identified several directions for future research, and the need to conduct more contextual studies in low- and middle-income nations to bring out the cross-cultural nuances of vaccine hesitancy.

Predictors of vaccine uptake during a pandemic: The interplay of lifetime discrimination, educational attainment, and family support

The experience of discrimination can have significant health implications, especially during a global pandemic. This study examines how lifetime discrimination, educational attainment (measured in years of education), and family support individually and interactively predict COVID-19 vaccine uptake. Low educational attainment may amplify the impact of discrimination due to increased vulnerability to misinformation. Conversely, family support can buffer the negative effects of discrimination on health behaviors by mitigating how stressors adversely influence health decisions. We utilized national data from the Midlife in the United States (N = 2004; aged 25-74). The results showed that although lifetime discrimination did not predict vaccine uptake, interaction analyses revealed that lifetime discrimination, in combination with higher educational attainment predicted lower vaccine uptake. In addition, family support moderated the relationship between lifetime discrimination and vaccine uptake, buffering its negative impact. These findings highlight the complex interplay of factors influencing COVID-19 vaccination decisions.

Community Cohesion, Social Support, and Mental Health among Black Individuals in Chicago: A Cross-Sectional Examination of the Effects on COVID-19 Vaccination

The COVID-19 pandemic put a significant strain on communities, social resources, and personal relationships, disproportionately impacting Black and low-income communities in the United States. Community cohesion and social support are positively associated with numerous health outcomes and preventive health measures, yet were strained during the pandemic due to COVID mitigation measures. This study examined the relationships between social cohesion, social support, mental health, and COVID-19 vaccination to understand whether community cohesion and social support were associated with increased likelihood of receiving a COVID-19 vaccination. Data are from a cross-sectional survey of 537 Black Chicagoans that was disseminated between September 2021 and March 2022. Structural equation modeling was used to test associations between community cohesion, social support, loneliness, anxiety, stress, and having received a COVID-19 vaccination. Results demonstrated that social support mediated associations between community cohesion and loneliness, anxiety, and stress, but was not associated with COVID-19 vaccination. These results demonstrate the importance of community cohesion and social support on mental health and suggest there are other potential pathways that may link community cohesion and vaccination.

Higher identity resilience - self-efficacy is associated with sexual risk behaviours in gay men

Cross-sectional survey data from 226 heterosexual and 201 gay men in the UK and Germany, analysed using moderation analyses, showed a positive relationship between identity resilience -self-efficacy and engaging in condomless sex and drug use in sexualised settings in gay men only. It is proposed that higher self-efficacy may lead to increased feelings of invincibility in gay men, which in turn is associated with sexual risk-taking.

COVID-19 Testing Behavior as a Predictor of COVID-19 Vaccination in Southeastern Louisiana: A Longitudinal Cohort Study

Background: Global COVID-19 vaccination effort faces the challenges of vaccine hesitancy and resistance, rooted in misinformation and institutional distrust. Addressing these barriers with customized messaging is essential, yet the relationship between vaccine hesitancy and other health-seeking behaviors, like COVID-19 testing, has been underexplored. Method: This study assessed COVID-19 vaccine uptake in Southeastern Louisiana across 10 pharmacies and clinics in areas with historically high rates of COVID-19 infection. Using a longitudinal cohort design from Fall 2022 through Fall 2023, a total of 377 participants from diverse backgrounds were surveyed while seeking routine care at partner organizations. Baseline data was collected on demographics, vaccine knowledge, attitudes, and test-seeking behaviors. Information on COVID-19 testing and vaccination were self-reported and verified, as applicable, in the patient's medical records. All data was analyzed using descriptive statistics, log-binomial to yield risk ratios, and an ordinal logistic regression for vaccine series completion. Results: Among the 377 participants, 207 were unvaccinated while 170 received the vaccine. Among the unvaccinated individuals, 53 received a half-dose, 97 a full dose, and 14 a booster. Notably, 75% of unvaccinated and 89% of vaccinated participants underwent COVID-19 testing. Individuals who were tested were 1.71 times more likely to be vaccinated (95% CI 1.03, 2.84), while previous vaccine refusal was associated with lower vaccine acceptance (0.77; 95% CI 0.54, 1.09). In the bivariate and multivariate analysis, COVID-19 testing behavior was positively associated with COVID-19 vaccine uptake. Conclusions: Exploring the connection between COVID-19 testing and vaccination provides valuable insights for future public health messaging to mitigate vaccine hesitancy.

The protective power of dissent? A longitudinal study on cognitive and socio-emotional determinants of COVID-19 vaccine hesitancy among young people in Canada

COVID-19 has elicited polarized reactions to public health measures, fueling anti-vaccination movements worldwide which indicate that vaccine hesitancy represents a common expression of dissent. We investigate changes in cognitive (i.e., trust in government, conspiracy beliefs, vaccine attitudes, and other COVID-19-related factors) and socio-emotional factors (i.e., psychological distress and social support) over time, and examine if these factors are associated with COVID-19 vaccine hesitancy. A sample of Canadian young adults (N = 2,695; 18 to 40 years old) responded to an online survey in May/June 2021 (after the first vaccination campaign) and then in November 2021 (after vaccine mandates were introduced). Based on survey answers, participants were categorized as "not hesitant", "hesitant", and "do not intend to get vaccinated" at each time point. Results from generalized estimating equation models indicate that vaccination hesitancy decreased over time. The importance attributed to specific COVID-19-related factors (e.g., research and science about COVID-19 vaccines, opinions of friends and family) decreased whereas psychological distress increased over time. Cognitive and socio-emotional factors were associated with vaccine hesitancy, with participants who did not intend to get vaccinated reporting the lowest psychological distress scores. We argue that dissent may be an empowering way for young people to restore a sense of personal agency via the opposition to a system perceived as illegitimate and/or unfair. These results raise important questions about potential collateral effects of top-down government and public health interventions in times of crisis.

Investigating the influencing factors of vaccination decisions for newly developed and established vaccines: a comparative study based on latent class logit models in China

Background

The factors influencing vaccination decision-making for newly developed vaccines may be similar to and different from those for established vaccines. Understanding these underlying differences and similarities is crucial for designing targeted measures to promote new vaccines against potential novel viruses.

Objective

This study aims to compare public vaccination decisions for newly developed and established vaccines and to identify the differences and similarities in the influencing factors.

Method

A discrete choice experiment (DCE) was conducted on 1,509 representatives of the general population in China to collect data on preferences for the coronavirus disease 2019 (COVID-19) and influenza vaccines, representing the newly developed and established vaccines, respectively. The latent class logit model was used to identify latent classes within the sample, allowing for an analysis of the factors distinctly influencing choices for both types of vaccines.

Result

Participants valued similar attributes for both vaccines. However, concerns about sequelae were more significant for the newly developed vaccine, while effectiveness was prioritized for the established vaccine. Class membership analysis revealed these differences and similarities were significantly correlated with age, health, yearly household income, acquaintances' vaccination status, and risk perception.

Conclusion

The study highlights the need for tailored communication strategies and targeted vaccination interventions. For the newly developed vaccines, addressing concerns about side effects is more crucial. For long-standing vaccines, emphasizing their effectiveness can enhance uptake more significantly. Engaging healthcare providers and community influencers is essential for both vaccines to increase public confidence and vaccination rates. Clear communication and community engagement are critical strategies for addressing public concerns and misinformation, particularly during periods of heightened concern.

Understanding and mitigating negative affect in preventive health behaviors: Evidence from the COVID-19 vaccination process

The study investigated the willingness for vaccine uptake during the COVID-19 pandemic (April-June 2021), and explored the effect of both mindfulness and health education in managing negative affect post-vaccination. In study 1, a sample of 468 Chinese college students completed a one-time survey, assessing loneliness, stress, medical fear, and vaccination likelihood. Results showed that medical fear mediated the relationship between loneliness, stress and vaccination likelihood. In study 2, 70 college students were randomly assigned to one of three intervention conditions (mindfulness, health education, and control) during vaccination. Participants in mindfulness group showed lower negative affect scores than the control group post-intervention (p = 0.019). However, no significant difference was reported between health education with the other two conditions. As such, medical fear would be an important factor to target for improving the likelihood of vaccine uptake. Furthermore, a short mindfulness intervention was effective to improve experience of vaccination through mitigating negative affect.

COVID-19 and EQ-5D-5L health state valuation

BACKGROUND

We investigate whether and how general population health state values were influenced by the initial stages of the COVID-19 pandemic. Changes could have important implications, as general population values are used in health resource allocation.

DATA

In Spring 2020, participants in a UK general population survey rated 2 EQ-5D-5L states, 11111 and 55555, as well as dead, using a visual analogue scale (VAS) from 100 = best imaginable health to 0 = worst imaginable health. Participants answered questions about their pandemic experiences, including COVID-19's effect on their health and quality of life, and their subjective risk/worry about infection.

ANALYSIS

VAS ratings for 55555 were transformed to the full health = 1, dead = 0 scale. Tobit models were used to analyse VAS responses, as well as multinomial propensity score matching (MNPS) to create samples balanced according to participant characteristics.

RESULTS

Of 3021 respondents, 2599 were used for analysis. There were statistically significant, but complex associations between experiences of COVID-19 and VAS ratings. For example, in the MNPS analysis, greater subjective risk of infection implied higher VAS ratings for dead, yet worry about infection implied lower ratings. In the Tobit analysis, people whose health was affected by COVID-19 rated 55555 higher, whether the effect on health was positive or negative.

CONCLUSION

The results complement previous findings that the onset of the COVID-19 pandemic may have impacted EQ-5D-5L health state valuation, and different aspects of the pandemic had different effects.

Longitudinal Association Between Social Isolation and COVID-19 Vaccine Uptake in Japanese Older Citizen: an Observational Study

BACKGROUND

Social isolation is associated with decreased intent to receive vaccination against coronavirus disease 2019 (COVID-19); however, its association with COVID-19 vaccine uptake is unknown.

OBJECTIVE

The present study aimed to determine the association between social isolation and subsequent COVID-19 vaccination using the data from a representative Japanese sample.

DESIGN

Longitudinal observational study.

PARTICIPANTS

Japanese citizens aged  ≥ 65 years who participated in the Quality of Life in COVID-19 Era (QoLCoVE) study which began in March 2020.

MAIN MEASURES

Social isolation was assessed in March 2020 using the abbreviated Lubben Social Network Scale, with a score of  ≤ 11 indicating social isolation. To evaluate the relationship between social isolation at the baseline and COVID-19 vaccine uptake (including reservation for vaccine administration) between August and September 2021, we estimated adjusted risk ratios with 95% CIs using modified Poisson regression with adjustment for potential confounders.

KEY RESULTS

A total of 921 participants met the inclusion criteria in the initial survey, of whom 720 (78.2%) completed the follow-up survey. Median age was 70 years (interquartile range: 66-72), and 329 (45.7%) participants were male. Twenty-one (16.5%) of 127 socially isolated participants, and 48 (8.1%) of 593 non-socially isolated participants did not receive the COVID-19 vaccine. Socially isolated participants were less likely to take COVID-19 vaccine than non-socially isolated participants (adjusted risk ratio 1.98, 95% CI: 1.18-3.32).

CONCLUSIONS

Social isolation is associated with reduced COVID-19 vaccine uptake among older adults. To further promote COVID-19 vaccination in the older population, support for social isolation might be necessary.

A National Study of Marital Status Differences in Early Uptake of COVID-19 Vaccine among Older Americans

We provide one of the first nationally representative studies to examine COVID-19 vaccine uptake differences by marital status within the first year after the vaccine was recommended among older Americans. Data were drawn from the National Health and Aging Trends Study (2021). The study sample included 3180 participants aged 65 and older with 1846 women and 1334 men. Results from logistic regression models suggest that divorced/separated older adults were less likely to receive at least one dose of the COVID-19 vaccine in 2021 than their married counterparts, especially among women and individuals with higher education. Widowed and never married respondents were generally not significantly different from married respondents in COVID-19 vaccination status, with only one exception: less-educated never-married respondents were more likely to receive COVID-19 vaccination than their less-educated married counterparts. Our study highlights divorce/separation as a significant social factor associated with COVID-19 vaccine uptake among older adults in the U.S. These findings suggest that divorced/separated older adults are the most vulnerable population segment at risk of low COVID-19 vaccine uptake. Future efforts to improve vaccine equity and uptake should target this group specifically, with tailored interventions to increase their access and uptake of the vaccine.

Can Risk Communication Surveillance Prompt COVID-19 Vaccine Acceptance among Internet users? Applying the Situational Theory of Problem Solving: A Cross-Sectional Study

BACKGROUND

The World Health Organization has recently raised concerns about the low number of fully vaccinated people against COVID-19 among developing countries. The low ratio of fully vaccinated people and the emergence of renewed infectious variants correspond to worsening public health. Global health managers have highlighted COVID-19 vaccine-related infodemics as the significant risk perception factor that hinders mass vaccination campaigns.

OBJECTIVE

Given the ambiguous digital communication environment which has fostered infodemics, developing nations struggle to boost public willingness to get people fully vaccinated. Authorities have launched some risk communication-laden digital interventions in response to infodemics. However, the value of these risk communication strategies employed to tackle infodemics needs to be evaluated. The current research using the tenets of the situational theory of problem-solving is novel, as it explores the impending effects of risk communication strategies. The relationship between infodemic-induced risk perception about COVID-19 vaccine safety and risk communication actions to intensify willingness to get fully vaccinated was examined.

METHODS

This research used a cross-sectional research design vis-à-vis nationally representative online survey. We collected data from 1946 internet users across Pakistan. Participants voluntarily participated in this research after filling consent form and reading the ethical permissions. Responses were received over three months, from May 2022 to July 2022.

RESULTS

The results delineated that infodemics positively affect risk perception. This realization pushed the public to engage in risky communicative actions through reliance on and search for accurate information. Therefore, the prospect of managing infodemics through risk information exposure (e.g., digital interventions) using the situational context could predict robust willingness to get fully vaccinated against COVID-19.

CONCLUSIONS

The pioneering results offer strategic considerations for health authorities to effectively man-age the descending spiral of optimal protection against COVID-19. This research concludes that the likelihood of managing infodemics using the situational context through exposure to relevant information could improve one's knowledge of forfending and selection, which can lead to robust protection against COVID-19. Hence, more situation-specific information about the underpinning problem (i.e., selection of appropriate vaccine) can be made accessible through several official digital sources to achieve a more active public health response.

Role of perceived social support in COVID-19 vaccine uptake among U.S. adults

Background

Vaccine uptake concerns in the Unites States were at the forefront of public health discussions during the COVID-19 pandemic. By the end of 2022, approximately 80% of the U.S. population was vaccinated against the virus. This study examined the relationship between perceived social support and COVID-19 vaccine uptake among U.S. adults.

Methods

Using nationally representative cross-sectional data on 21,107 adults from the 2021 National Health Interview Survey, we assessed the COVID-19 vaccination rates across individuals with strong, some, and weak levels of social support. Multivariable logistic regression models were estimated to obtain the odds of being vaccinated in adults with different levels of perceived social support for the full sample and sub-samples of age groups.

Results

We found that compared to adults with perceived strong social support, adults with weak social support were 21.1% less likely to be vaccinated against COVID-19. Apart from the age 18-24 years group, the lower likelihood of being vaccinated for adults with weak social support was evident in age 24-49 years (AOR=0.66, 95% CI: 0.52-0.85), age 50-64 years (AOR=0.67, 95% CI: 0.50-0.90), and age 65+ years (AOR=0.56, 95% CI: 0.41-0.75) groups.

Conclusions

These findings are consistent with a broader literature indicating that social support increases the likelihood of healthy behaviors and decreases risky behaviors. Interventions designed to improve the perception of social support, particularly among those at high risk of mortality from COVID-19 may be a promising tactic for increasing COVID-19 vaccine uptake.

Cognitive and Emotional Motivation to Explain Infection-Prevention Behaviors with Social Support as a Mediator During the COVID-19 Pandemic: A Nationwide Cross-Sectional Study in Korea

Purpose

To predict the performance of infection-prevention behaviors among adults in Korea based on the health belief model, using social support as a mediator.

Patients and Methods

A nationwide cross-sectional survey of 700 participants from the local community was conducted using both online and offline methods from 8 metropolitan cities and 9 provinces in Korea from November 2021 to March 2022. The questionnaire was composed of 4 sections: demographic information, motivational factors for behavior change, social support, and infection-prevention behaviors. Data were analyzed using structural equation modeling with the AMOS program. The general least-squares method was applied to assess the fit of the model and the bootstrapping method was tested for indirect effect and the total effect.

Results

Motivation factors that directly affected infection-prevention behaviors were self-efficacy (γ=0.58, p<0.001), perceived barriers (γ=-.08, p=0.004), perceived benefits (γ=0.10, p=0.002), perceived threats (γ=0.08, p=0.009), and social support (γ=0.13, p<0.001), after controlling for related demographic variables. Cognitive and emotional motivation factors together explained 59% of the variance in infection-prevention behaviors. Social support exerted significant mediating effects between each cognitive and emotional motivation variable and infection-prevention behaviors, along with a significant direct effect on infection-prevention behaviors (γ=0.12, p<0.001).

Conclusion

The engagement of prevention behaviors among community-dwelling adults was influenced by their self-efficacy, perceived barriers, perceived benefits, and perceived threats with social support as a mediator. Prevention policy approaches could include providing specific information to improve self-efficacy and build awareness of the severity of the disease while establishing a supportive social environment for promoting health behaviors during the COVID-19 pandemic.

Drivers of SARS-CoV-2 testing behaviour: a modelling study using nationwide testing data in England

During the COVID-19 pandemic, national testing programmes were conducted worldwide on unprecedented scales. While testing behaviour is generally recognised as dynamic and complex, current literature demonstrating and quantifying such relationships is scarce, despite its importance for infectious disease surveillance and control. Here, we characterise the impacts of SARS-CoV-2 transmission, disease susceptibility/severity, risk perception, and public health measures on SARS-CoV-2 PCR testing behaviour in England over 20 months of the pandemic, by linking testing trends to underlying epidemic trends and contextual meta-data within a systematic conceptual framework. The best-fitting model describing SARS-CoV-2 PCR testing behaviour explained close to 80% of the total deviance in NHS test data. Testing behaviour showed complex associations with factors reflecting transmission level, disease susceptibility/severity (e.g. age, dominant variant, and vaccination), public health measures (e.g. testing strategies and lockdown), and associated changes in risk perception, varying throughout the pandemic and differing between infected and non-infected people.

Identity resilience, science mistrust, COVID-19 risk and fear predictors of vaccine positivity and vaccination likelihood: A survey of UK and Portuguese samples

Based on Identity Process Theory, we hypothesised that two elements of identity resilience (identity worth and identity continuity) differentially predict variance in COVID-19 fear and risk, science mistrust, vaccine positivity, and vaccination likelihood. Data from an online survey of 643 UK and 485 Portuguese adults collected during March 2021 showed the UK and Portuguese did not differ significantly on vaccination likelihood or identity resilience. UK respondents reported less science mistrust, COVID-19 risk, and fear, but higher vaccine positivity than the Portuguese. Identity worth and identity continuity differed between countries in their effects on science mistrust, COVID-19 fear, risk, vaccine positivity and vaccination likelihood. Science mistrust and COVID-19 fear proved key factors in predicting vaccine positivity and vaccination likelihood. We conclude the roles of discrete elements of identity resilience in health behaviour require further examination and action reducing prevalence of specific forms of science mistrust can improve vaccination likelihood.

Intent to vaccinate against SARS-CoV-2 and its determinants across six ethnic groups living in Amsterdam, the Netherlands: A cross-sectional analysis of the HELIUS study

BACKGROUND

Ethnic minority groups experience a disproportionately high burden of infections, hospitalizations and mortality due to COVID-19, and therefore should be especially encouraged to receive SARS-CoV-2 vaccination. This study aimed to investigate the intent to vaccinate against SARS-CoV-2, along with its determinants, in six ethnic groups residing in Amsterdam, the Netherlands.

METHODS

We analyzed data of participants enrolled in the population-based multi-ethnic HELIUS cohort, aged 24 to 79 years, who were tested for SARS-CoV-2 antibodies and answered questions on vaccination intent from November 23, 2020 to March 31, 2021. During the study period, SARS-CoV-2 vaccination in the Netherlands became available to individuals working in healthcare or > 75 years old. Vaccination intent was measured by two statements on a 7-point Likert scale and categorized into low, medium, and high. Using ordinal logistic regression, we examined the association between ethnicity and lower vaccination intent. We also assessed determinants of lower vaccination intent per ethnic group.

RESULTS

A total of 2,068 participants were included (median age 56 years, interquartile range 46-63). High intent to vaccinate was most common in the Dutch ethnic origin group (369/466, 79.2%), followed by the Ghanaian (111/213, 52.1%), South-Asian Surinamese (186/391, 47.6%), Turkish (153/325, 47.1%), African Surinamese (156/362, 43.1%), and Moroccan ethnic groups (92/311, 29.6%). Lower intent to vaccinate was more common in all groups other than the Dutch group (P < 0.001). Being female, believing that COVID-19 is exaggerated in the media, and being < 45 years of age were common determinants of lower SARS-CoV-2 vaccination intent across most ethnic groups. Other identified determinants were specific to certain ethnic groups.

CONCLUSIONS

Lower intent to vaccinate against SARS-CoV-2 in the largest ethnic minority groups of Amsterdam is a major public health concern. The ethnic-specific and general determinants of lower vaccination intent observed in this study could help shape vaccination interventions and campaigns.

Racial and ethnic disparities in COVID-19 vaccine uptake: A mediation framework

BACKGROUND

Previous research suggests that racial and ethnic minority groups especially Black Americans showed stronger COVID-19 vaccine hesitancy and resistance, which may result from a lack of trust toward the government and vaccine manufacturers, among other sociodemographic and health factors.

OBJECTIVES

The current study explored potential social and economic, clinical, and psychological factors that may have mediated racial and ethnic disparities in COVID-19 vaccine uptake among US adults.

METHODS

A sample of 6078 US individuals was selected from a national longitudinal survey administered in 2020-2021. Baseline characteristics were collected in December 2020, and respondents were followed up to July 2021. Racial and ethnic disparities in time to vaccine initiation and completion (based on a 2-dose regimen) were first assessed with the Kaplan-Meier Curve and log-rank test, and then explored with the Cox proportional hazards model adjusting for potential time-varying mediators, such as education, income, marital status, chronic health conditions, trust in vaccine development and approval processes, and perceived risk of infection.

RESULTS

Prior to mediator adjustment, Black and Hispanic Americans had slower vaccine initiation and completion than Asian Americans and Pacific Islanders and White Americans (p's < 0.0001). After accounting for the mediators, there were no significant differences in vaccine initiation or completion between each minoritized group as compared to White Americans. Education, household income, marital status, chronic health conditions, trust, and perceived infection risk were potential mediators.

CONCLUSION

Racial and ethnic disparities in COVID-19 vaccine uptake were mediated through social and economic conditions, psychological influences, and chronic health conditions. To address the racial and ethnic inequity in vaccination, it is important to target the social, economic, and psychological forces behind it.

Exposure, perceived risk, and psychological distress among general population during the COVID-19 lockdown in Wuhan, China

Introduction

The COVID-19 pandemic that has been going on since the end of 2019 impacts people on both the physical and psychological levels. However, the psychological status, especially its underlying psychosocial mechanisms among the general population in Wuhan, the earliest epicenter and hardest-hit city in China during the pandemic, has not been well investigated. This study aimed to examine the relationships between exposures, perceived risk, and psychological distress among the general population in Wuhan during the COVID-19 lockdown.

Methods

Data were from a cross-sectional online survey conducted from 20 February to 4 March 2020. Final analyses included 4,234 Wuhan respondents. A 5-item Hopkins Symptom Checklist was adopted to assess respondents' psychological distress.

Results

It was found that nervousness, fear, and worry were the most common symptoms among Wuhan residents during the lockdown. Exposure within a close physical distance, exposure within the social network, and perceived risk are significantly positively related to respondents' psychological distress. Moreover, perceived risk mediated the effects of exposures on respondents' psychological condition.

Discussion

These findings conduce to identify the populations at higher risk of suffering psychological disturbance during the pandemic and are expected to inform the policymakers and mental health professionals to monitor and improve the perception of risk among the target population by appropriate interventions.

Predisposing, Enabling, and Reinforcing Factors of COVID-19 Prevention Behavior in Indonesia: A Mixed-methods Study

OBJECTIVES

To prevent the spread of coronavirus disease 2019 (COVID-19), behaviors such as mask-wearing, social distancing, decreasing mobility, and avoiding crowds have been suggested, especially in high-risk countries such as Indonesia. Unfortunately, the level of compliance with those practices has been low. This study was conducted to determine the predisposing, enabling, and reinforcing factors of COVID-19 prevention behavior in Indonesia.

METHODS

This cross-sectional study used a mixed-methods approach. The participants were 264 adults from 21 provinces in Indonesia recruited through convenience sampling. Data were collected using a Google Form and in-depth interviews. Statistical analysis included univariate, bivariate, and multivariate logistic regression. Furthermore, qualitative data analysis was done through content analysis and qualitative data management using Atlas.ti software.

RESULTS

Overall, 44.32% of respondents were non-compliant with recommended COVID-19 prevention behaviors. In multivariate logistic regression analysis, low-to-medium education level, poor attitude, insufficient involvement of leaders, and insufficient regulation were also associated with decreased community compliance. Based on in-depth interviews with informants, the negligence of the Indonesian government in the initial stages of the COVID-19 pandemic may have contributed to the unpreparedness of the community to face the pandemic, as people were not aware of the importance of preventive practices.

CONCLUSIONS

Education level is not the only factor influencing community compliance with recommended COVID-19 prevention behaviors. Changing attitudes through health promotion to increase public awareness and encouraging voluntary community participation through active risk communication are necessary. Regulations and role leaders are also required to improve COVID-19 prevention behavior.

Social Support Mediates the Relationship between COVID-19-Related Burnout and Booster Vaccination Willingness among Fully Vaccinated Nurses

COVID-19 booster doses for high-risk groups such as nurses are necessary to reduce the impacts of the pandemic and promote public health. We examined the relationship between COVID-19-related burnout and booster vaccination willingness among nurses, and we assessed whether social support can buffer this relationship. We conducted a cross-sectional study with 963 fully vaccinated nurses working in healthcare settings in Greece. We used the multidimensional scale of perceived social support to measure social support and the COVID-19 burnout scale to measure COVID-19-related burnout. We measured vaccination willingness with a scale from 0 (extremely unlikely to take a booster dose) to 10 (extremely likely). Among nurses, 37.1% reported being very likely to be vaccinated, 34.4% reported being uncertain about their likelihood of vaccination, and 28.6% reported being very unlikely to be vaccinated with a booster dose. We found that COVID-19-related burnout reduced vaccination willingness, while social support functioned as a partial mediator of this relationship. In conclusion, nurses who experienced burnout were less likely to accept a booster dose. Furthermore, increasing nurses' social support reduced the negative effects of burnout, resulting in improved booster vaccination willingness. Immunization awareness programs should be implemented in order to address nurses' concerns and support booster doses.

Predictive capacity of COVID-19-related risk beliefs on weight management behaviors on a commercial weight loss program and speed of COVID-19 vaccination uptake: prospective cohort study

BACKGROUND

Recent work has shown that obesity may be a risk factor for severe COVID-19. However, it is unclear to what extent individuals have heard or believe this risk factor information, and how these beliefs may predict their preventive behaviors (e.g., weight management behaviors or COVID-19 preventive behaviors). Previous work has primarily looked at overall risk likelihood perceptions (i.e., not about obesity as a risk factor) within general populations of varying weight and concentrated on COVID-19-related preventive behaviors. Therefore, this prospective cohort study explored whether beliefs about obesity as a risk factor and overall risk likelihood perceptions predicted weight management and COVID-19 preventive behaviors over the next 16 weeks in individuals with obesity or overweight.

METHODS

Participants were 393 individuals in the US who joined a commercial weight management program in January, 2021. We leveraged the mobile program's automatic measurement of real-time engagement in weight management behaviors (e.g., steps taken), while surveys measured risk beliefs at baseline as well as when individuals received COVID-19 vaccination doses (asked monthly) over the next 16 weeks. Mixed effects models predicted engagement and weight loss each week for 16 weeks, while ordinal logistic regression models predicted the month that individuals got vaccinated against COVID-19.

RESULTS

We found that belief in obesity as a risk factor at baseline significantly predicted greater engagement (e.g., steps taken, foods logged) in program-measured weight management behaviors over the next 16 weeks in models adjusted for baseline BMI, age, gender, and local vaccination rates (minimally adjusted) and in models additionally adjusted for demographic factors. Belief in obesity as a risk factor at baseline also significantly predicted speed of COVID-19 vaccination uptake in minimally adjusted models but not when demographic factors were taken into account. Exposure to obesity risk factor information at baseline predicted greater engagement over 16 weeks in minimally adjusted models.

CONCLUSIONS

The results highlight the potential utility of effective education to increase individuals' belief in obesity risk factor information and ultimately promote engagement or faster vaccination. Future research should investigate to what extent the results generalize to other populations.

Identifying Drivers of COVID-19 Vaccine Uptake among Residents of Yopougon Est, Abidjan, Côte d'Ivoire

This study applied the Fogg Behavioral Model (FBM) to identify and prioritize factors influencing COVID-19 vaccination among residents of Yopougon Est, Abidjan, Côte d'Ivoire. A total of 568 respondents were recruited from among individuals entering eleven participant recruitment and data collection sites located near high pedestrian trafficked areas. Among all respondents, 52% reported being vaccinated versus 48% who reported not being vaccinated. Of those who reported being vaccinated, 42% reported received a single dose, 54% a double dose, and 4% three or more doses. A categorical regression analysis suggested that potential predictors of COVID-19 vaccination included acceptance and rejection factors, which are both aligned with motivation in the FBM and socio-demographic characteristics, proximity to services, and religion. Our findings suggest that demand creation activities should target individuals with less formal education, those who are not formally employed, non-Catholic Christians, and individuals who do not identify as Akan. Results also suggest the need to design programmatic messages and activities that focus on generating family and community support for COVID-19 vaccination.

A comprehensive examination of association between belief in vaccine misinformation and vaccination intention in the COVID-19 context

Misinformation about COVID-19 vaccines is widely available in the public communication environment. Exposure to the misinformation may increase perceived risk of and evoke negative emotions toward COVID-19 vaccines that may eventually reduce COVID-19 vaccination intentions. The negative influences of misinformation may vary by aspects of individuals' social networks. Expanding the reasoned action approach, we proposed a comprehensive model to examine the roles of misinformation beliefs, perceived risk, fear, worry, and social networks in explaining COVID-19 vaccination intentions. We tested the model using survey data of South Korean adults, collected when the Korean government launched its nationwide vaccination program in April 2021 (n = 744). The results from our step-by-step path analyses indicated that COVID-19 vaccination intentions had positive direct associations with vaccination-specific factors such as attitudes toward, injunctive norms on, and perceived behavioral control over COVID-19 vaccination. Perceived risk was also directly linked to intentions. Among these factors, attitudes and injunctive norms were most strongly related to intentions. Misinformation beliefs and worry had negative indirect relationships with intentions via the mediation of these variables directly connected to intentions. The negative influences of misinformation beliefs were greater among respondents reported stronger tie strengths. Theoretical and practical implications were discussed.

Factors associated with COVID-19 vaccination behaviour in Latvian population: cross-sectional study

Vaccination is the most effective way of limiting the spread of COVID-19. However, despite the proven effectiveness and safety of vaccines, there is resistance in society and the course of vaccination is slow. The aim of this study was to identify the factors associated with COVID-19 vaccination behaviour. Methods: The data originate from a representative sample of Latvian residents (N  = 1017) taken in September 2021. The data were analysed using Chi-squared test, Mann-Whitney test, Spearman's rank correlation coefficient, Kruskal Wallis test, and Binary Logistic regression analysis. Results: The results of the study reveal several factors that are associated with COVID-19 vaccination behaviour. These factors are a higher level of education, motivation for protecting oneself against illness, for promoting collective immunity, protecting relatives and other people from infection, as well as motivation for vaccination in order to keep a job or continue studies, and institutional trust. On the other hand, perceived social support from relatives is negatively associated with vaccination behaviour. Conclusion: A higher level of education and confidence in evidence-based information on COVID-19, provided by official sources of information, is the key factor in deciding whether to protect oneself from serious illness or to make a choice to promote collective immunity and protect other people. The need for vaccination in order to continue working and/or learning is also an essential motive for vaccination. On the other hand, the belief that, if necessary, it is possible to receive support from relatives may be a delaying factor in the behaviour of vaccination.

Exploring posttraumatic growth after the COVID-19 pandemic

Although it is undeniable that the COVID-19 pandemic presented new threats and traumas for human beings, posttraumatic growth that took place after the struggle with this highly challenging crisis cannot be ignored. Therefore, based on the posttraumatic growth theory, the present research focuses on aspects of tourists' positive changes after the COVID-19 outbreak. A total of 1165 potential tourists from 197 cities in 31 provinces of China were analyzed using symmetrical and asymmetrical approaches. The results of the partial least squares test revealed the net effects of social support, psychological distress, and infection risk perception on the three dimensions of tourists' posttraumatic growth, namely, travel risk aversion, social identity, and altruistic behavior. Fuzzy-set qualitative comparative analysis provided causal recipes for realizing posttraumatic growth, and necessary condition analysis supplemented the necessary antecedents. The implications of the findings and the paths for future research are also presented.

The Impact of COVID-19 Related Social Distancing on Mental Health Outcomes: A Transdiagnostic Account

The COVID-19 pandemic, and the social distancing practices that followed, have been associated with increased prevalence of emotional disorders. However, not all individuals affected by COVID-19-related social distancing experienced elevations in emotional disorder symptoms. Understanding this phenomenon is of crucial public health significance given the burden of emotional disorders on individuals and systems. In this narrative review, we consider the differential impact of COVID-19-related social distancing on mental health outcomes from a transdiagnostic perspective. We argue that individuals high in negative affect and aversive reactivity to emotion, that is, neuroticism, and who respond to such emotional experiences with emotion-motivated avoidant coping, are most likely to experience emotional disorders in the context of COVID-19 social distancing. We acknowledge the pro-social and adaptive function of some types of avoidance during the pandemic, which may have initially buffered against negative mental health outcomes. Implications of this conceptualization for treatment of emotional disorders in the present sociocultural context are discussed.

Influences of nationality and national identification on perceived dangerousness of COVID-19 variants and perceived effectiveness of COVID-19 vaccines: A study of UK and Portuguese samples

During the COVID-19 pandemic, both variants of the virus that causes the disease and vaccines developed to combat it have been identified with nationalities. Both social identity theory and identity process theory would predict that this would initiate intergroup differentiation processes aimed at optimizing ingroup value and personal identity enhancement. Our study examined whether people’s nationality and level of national identification influence their perception of dangerousness of variants and effectiveness of vaccines. We compared data collected by online survey in March 2021 from the UK (which was associated with both a variant and a vaccine) and Portugal (which was associated with neither). The Portuguese rated variants overall as more dangerous than did the UK sample. The Chinese variant was rated by both samples as the least dangerous and the UK sample rated the British variant as less dangerous than did the Portuguese. Higher national identification in the UK sample was associated with differentiating more between the British variant and the South African variant and differentiating it less from the Chinese variant. The UK sample rated the effectiveness of the British vaccine higher than did the Portuguese. They also evaluated it as more effective than the American, Chinese and Indian vaccines. In both samples, higher national identification was associated with lower ratings of effectiveness for vaccines originating in China or India. Our study suggests that identity processes associated with national identification do influence perceptions of vaccines and variants. This has significant practice and policy implications. Social representations of variants and vaccines in nationalistic terms can have complex and unexpected consequences.

The Effect of Risk Perception on Anxiety in Emerging Adulthood Under the Local Outbreak of COVID-19: A Conditional Process Analysis

This study aims to explore the influence mechanism of COVID-19 risk perception on anxiety in emerging adulthood in the context of public health events of the second round of COVID-19 outbreaks and provide support for exploring the path of mental health after the normalization of the epidemic situation. An online questionnaire, combined with community social work, was used in this study, and data of 522 emerging adults were collected in February 2021. The Perceived Risk of COVID-19 pandemic scale (PRCPS), the generalized anxiety disorder 7-item (GAD-7) scale, the scale of affect balance, and the connor-davidson resilience scale (CD-RISC) were used to investigate. The results showed that: first, the risk perception of COVID-19 in early adulthood was positively predictive of anxiety symptoms [B = 0.110, p < 0.05, 95%CI = (0.042, 0.176)]. Second, the affective quality of life plays a mediating role between the risk perception of COVID-19 and anxiety [B = 0.108, 95%CI = (0.060, 0.161)]. Thirdly, resilience plays a moderating role between the risk perception of COVID-19 and anxiety, the higher the resilience of emerging adulthood, the weaker effects of the risk perception of COVID-19 negative prediction of anxiety [B = −0.110, p < 0.001, 95%CI = (−0.170, −0.049)]. Therefore, to control the anxiety of emerging adulthood in public health events, we should pay attention to the propaganda and management of epidemic information, improve the quality of life, and attention should be paid to the emerging adulthood with low resilience.

Optimization of a new adaptive intervention using the SMART Design to increase COVID-19 testing among people at high risk in an urban community

BACKGROUND

COVID-19 has impacted the health and social fabric of individuals and families living across the USA, and it has disproportionately affected people living in urban communities with co-morbidities, those working in high-risk settings, refusing or unable to adhere to CDC guidelines, and more. Social determinants of health (SDH), such as stigmatization, incarceration, and poverty, have been associated with increased exposure to COVID-19 and increased deaths. While vaccines and booster shots are available, it will take time to reach herd immunity, and it is unclear how long newly developed vaccines provide protection and how effective they are against emerging variants. Therefore, prevention methods recommended by the Centers for Disease and Control (CDC)-i.e., testing, hand-washing, social distancing, contact tracing, vaccination and booster shots, and quarantine-are essential to reduce the rates of COVID-19 in marginalized communities. This project will adapt and test evidence-based HIV interventions along the prevention and treatment cascade to help address COVID-19 prevention needs.

METHODS

The study aims to (1) optimize an adaptive intervention that will increase rates of testing and adherence to New Jersey State COVID-19 recommendations (testing, social distancing, quarantine, hospitalization, contact tracing, and acceptance of COVID-19 vaccination and booster shots) among high-risk populations and (2) identify predictors of testing completion and adherence to New Jersey recommendations. This study follows Community Based Participatory Research (CBPR) principles to conduct a Sequential, Multiple Assignment Randomized Trial (SMART) with 670 COVID-19 medically/socially vulnerable people. Participants will be recruited using a variety of strategies including advertisements on social media, posting fliers in public places, street outreach, facility-based, and snowball sampling. Participants complete a baseline survey and are randomized to receive navigation services or an electronic brochure. They then complete a follow-up 7 days after baseline and are randomized again to either continue with their original assignment or switch to the other intervention or critical dialog or brief counseling. Participants then complete a 5-week post-baseline follow-up. Guided by the COVID-19 Continuum of Prevention, Care, and Treatment, the analysis will explore the factors associated with COVID-19 testing within 7 days of the intervention.

DISCUSSION

This paper describes the protocol of the first study to use SMART following CBPR to adapt evidence-based HIV prevention interventions to COVID-19. The findings will inform the development of an effective and scalable adaptive intervention to increase COVID-19 testing and adherence to public health recommendations, including vaccination and booster shots, among a marginalized and difficult-to-engage population.

Willingness and uptake of the COVID-19 testing and vaccination in urban China during the low-risk period: a cross-sectional study

BACKGROUND

Regular testing and vaccination are effective measures to mitigate the ongoing COVID-19 pandemic. Evidence on the willingness and uptake of the COVID-19 testing is scarce, and the willingness and uptake of vaccination may change as the pandemic evolves. This study aims to examine willingness and uptake of COVID-19 testing and vaccination during a low-risk period of the COVID-19 pandemic in urban China.

METHODS

A cross-sectional online survey was conducted among 2244 adults in urban China. Descriptive analyses were performed to compare the respondents' willingness and uptake of COVID-19 testing and vaccination. Multivariate logistic regressions were fitted to investigate factors associated with the willingness and uptake of the two measures.

RESULTS

In early 2021, about half (52.45%) of the respondents had received or scheduled a COVID-19 test at least once, and a majority (95.63%) of the respondents were willing to receive testing. About two-thirds (63.28%) of the respondents had received/scheduled or were willing to receive a COVID-19 vaccine. Willingness and uptake of COVID-19 testing were not associated with socio-demographic characteristics, except for occupation. Being of older age, migrants, having higher educational attainment and secure employment were associated with a higher uptake of COVID-19 vaccination among the surveyed respondents, while willingness to vaccinate was consistent across socio-demographic characteristics among those who had not been vaccinated.

CONCLUSIONS

By early 2021, Chinese adults expressed almost universal willingness of COVID-19 testing and over half of adults have been tested, while the willingness and uptake of COVID-19 vaccination were relatively low at the low-risk period of the COVID-19 pandemic. Maintaining willingness of COVID-19 vaccination is critical and necessary, especially when the pandemic evolved into a low-risk period.

COVID-19 Vaccination Behavior of People Living with HIV: The Mediating Role of Perceived Risk and Vaccination Intention

The COVID-19 vaccination behavior of people living with HIV (PLWH) was examined via a cross-sectional web-based survey of PLWH aged 18 years and older. The survey was conducted from l May to 20 June 2021. The survey included social demographic information; vaccination behavior (B); and questions related to perceived usefulness (PU), perceived risk (PR), subjective norms (SNs), perceived behavior control (PBC), and behavior intention (BI). The associations between the questionnaire variables and COVID-19 vaccination behavior were assessed by calculating the descriptive data, correlation analysis, and structural equation modeling. In total, 43.71% of the 350 eligible respondents had received a COVID-19 vaccine. The differences in COVID-19 vaccination behavior according to age, gender, religious belief, marital status, income, education level, and occupation were not obvious (p > 0.05). PU had a significantly negative effect on PR (p < 0.05). PR had a significantly negative effect on BI (p < 0.05). SNs had a significantly positive effect on BI (p < 0.05). BI had a significantly positive effect on B (p < 0.05). PR fully mediated the effects of PU on BI, BI fully mediated the effects of PR on B, and BI fully mediated the effects of SNs on B (p < 0.05). Health policymakers and medical workers should provide more information about the risks of vaccine application to improve the vaccination behavior of PLWH.

Psychological distance towards COVID-19: Geographical and hypothetical distance predict attitudes and mediate knowledge

While different antecedents have been examined to explain peoples’ reactions towards COVID-19, there is only scarce understanding about the role of the subjective closeness and distance to the pandemic. Within the current study, we applied the concept of psychological distance to understand the distance towards COVID-19 and investigated its (1) connection with preventive attitudes and proactive behaviors, (2) context-specific antecedents, and its (3) mediating effect of knowledge on attitudes. Using an online sample from a German quantitative cross-sectional study (N = 395, M = 32.2 years, SD = 13.9 years, 64.3% female) in July 2020, a time with a general low incidence of people infected with Sars-CoV2, we measured relevant socio-psychological constructs addressing COVID-19 and included further information from external sources. Based on a path model, we found geographical distance as a significant predictor of cognitive attitudes towards COVID-19. Furthermore, hypothetical distance (i.e., feeling to be likely affected by COVID-19) predicted not only participants’ affective, cognitive, and behavioral attitudes, but also the installation of a corona warning-app. While several variables affected the different dimensions of psychological distance, hypothetical and geographical distance mediated the effect of knowledge on attitudes. These results underline the role of geographical and hypothetical distance for health-related behaviors and education. For example, people will only comply with preventive measures if they feel geographically concerned by the disease, which is particularly challenging for fast-spreading global diseases such as COVID-19. Therefore, there is a need to clearly communicate the personal risks of diseases and address peoples’ hypothetical distance.
