Change in anti‐COVID‐19 behaviour and anti‐immigrant prejudice during the COVID‐19 pandemic: Longitudinal evidence from five European countries

During a pandemic, it is vital to identify factors that motivate individuals to behave in ways that limit virus transmission (i.e., anti‐COVID‐19 behaviour). Fear has been suggested to motivate health‐oriented behaviour, yet fear of the virus (i.e., fear of COVID‐19) could have unintended consequences, such as an increase in anti‐immigrant prejudice. In a three‐wave longitudinal study (NT1 = 4275) in five European countries from April to October 2020, we investigated how social norms, the impact of the pandemic on individuals, and intergroup contact affected fear of COVID‐19 and—or in turn—anti‐COVID‐19 behaviour and prejudice towards immigrants. A latent change score model—distinguishing between intra‐ and inter‐individual changes in outcomes—indicated that fear of COVID‐19 influenced neither anti‐COVID‐19 behaviour nor prejudice. Anti‐COVID‐19 behaviour was increased by anti‐COVID‐19 norms (i.e., belief that others perform anti‐COVID‐19 behaviours), while prejudice was influenced by positive and negative direct and mass‐mediated intergroup contact.

Dependence analysis of social contact behaviors under the impacts of COVID-19 based on a copula approach.

The spread of the SARS-CoV-2 virus during the COVID-19 pandemic was intricately linked with contact between people, but many of the policies designed to encourage safe contact behaviors were unsuccessful. One reason was that the determinants of social contact decisions have not been thoroughly investigated using scientifically sound methodologies. To fill this gap, a unique survey was designed which sought data on social contact behaviors and their determinants. Second, a copula-based behavior model was developed to jointly represent the choices of contact modes (including direct and indirect contact) and the number of contacted persons. The survey was conducted in six countries from March to May 2021 and collected valid responses from >7000 people. A comparison of five key copula functions found that the Frank function outperformed the others. The results of a Frank-based model showed that indirect contacts were significantly and positively associated with the number of contacted persons. Then the influence of various determinants, including activity attributes (e.g., frequency and travel distance), protective measures, safety level of activity settings, and psychological factors related to activity participation and risk perception, were extensively analyzed. In particular, the various heterogeneous influences in different social contact settings were examined. The findings provide scientific evidence for policymakers to promote safe social distancing, even for the post-pandemic era.

Impact of tiered measures on social contact and mixing patterns of in Italy during the second wave of COVID-19.

BACKGROUND: Most countries around the world enforced non-pharmaceutical interventions against COVID-19. Italy was one of the first countries to be affected by the pandemic, imposing a hard lockdown, in the first epidemic wave. During the second wave, the country implemented progressively restrictive tiers at the regional level according to weekly epidemiological risk assessments. This paper quantifies the impact of these restrictions on contacts and on the reproduction number. METHODS: Representative (with respect to age, sex, and region of residence) longitudinal surveys of the Italian population were undertaken during the second epidemic wave. Epidemiologically relevant contact patterns were measured and compared with pre-pandemic levels and according to the level of interventions experienced by the participants. Contact matrices were used to quantify the reduction in the number of contacts by age group and contact setting. The reproduction number was estimated to evaluate the impact of restrictions on the spread of COVID-19. RESULTS: The comparison with the pre-pandemic baseline shows a significant decrease in the number of contacts, independently from the age group or contact settings. This decrease in the number of contacts significantly depends on the strictness of the non-pharmaceutical interventions. For all levels of strictness considered, the reduction in social mixing results in a reproduction number smaller than one. In particular, the impact of the restriction on the number of contacts decreases with the severity of the interventions. CONCLUSIONS: The progressive restriction tiers implemented in Italy reduced the reproduction number, with stricter interventions associated with higher reductions. Readily collected contact data can inform the implementation of mitigation measures at the national level in epidemic emergencies to come.

Older Adult Residents in Cohousing Communities: Impact and Response to the COVID-19 Pandemic

This cross-sectional study explored the experiences of older adults in cohousing communities in the United States during the COVID-19 pandemic. Cohousing- an intentionally designed collaborative housing community- provides opportunities for social support. Restrictions due to the pandemic may be associated with less opportunities for social and physical connectedness. Most participants did not feel lonely or left out but did feel isolated. Feeling lonely or left out were associated with poor health status, living alone, being single, and having less contact outside of the community. It was unclear if feeling isolated was a result of or was intensified due to the pandemic.

Auto-detection of social contact for fighting COVID-19 pandemic.

Because of the high infectivity of COVID-19, it is essential to detect the close contacts of patients as soon as possible to contain the outbreak of the epidemic. However, due to the level of technological development, the current methods and research on contact detection require manual participation. This paper proposes a future oriented automation method, which uses mobile agents loaded on sensing devices and edge coordinators to form a multi-agent system on the street. Based on perception, tracking and edge-computing, the contact probability between infected people and pedestrians is estimated. A series of simulations provide the comparison of parameters in application deployment. The simulation results show that the proposed street expropriation mode and edge-computing algorithm can further improve the detection rate.

Coping With Covid‐19: Older Europeans and the Challenges of Connectedness and Loneliness

Social networks are important for well‐being and healthy aging. However, older adults are more likely to have less social contact with others than their younger counterparts due to significant changes in their lives, such as retirement or age‐related losses, along with declining health and mobility. Consequently, with increasing age, a growing proportion of people experience feelings of loneliness. This becomes even more important during pandemics when social contact should be minimized. Therefore, this article examines the extent and patterns of loneliness before and during the first two years of the Covid‐19 pandemic and how social contact and the type of communication affected levels of loneliness during the pandemic. To investigate loneliness, social contact, and their association during the pandemic, this study uses representative data from 27 countries from SHARE (Survey of Health, Ageing, and Retirement in Europe). The analyses are based on a balanced panel covering three consecutive waves with 28,448 respondents aged 50 years or older. The results indicate that three out of ten Europeans face loneliness in later life. While loneliness has increased for a significant part of the elderly in the wake of the pandemic, there has also been a reverse trend in terms of a decrease in feelings of loneliness for an almost equal proportion of people. Additionally, multivariate analyses highlight that nonpersonal communication cannot substitute face‐to‐face interaction and can potentially increase feelings of loneliness. © 2023 by the author(s);licensee Cogitatio (Lisbon, Portugal).

Predictors and consequences of loneliness during the COVID-19 Pandemic.

The COVID-19 pandemic has created a global context in which social isolation has become normative in order to reduce the risk of COVID-19 transmission. As a result of social distancing policies, the risk for loneliness and associated decline in quality of life has increased. The current study examined factors associated with loneliness and quality of life during the COVID-19 pandemic cross-sectionally (n = 797) and longitudinally (n = 395). Older age and larger social network size were associated with less loneliness, whereas having multiple physical or mental health diagnoses was associated with greater loneliness. Greater virtual social contact was also associated with increased loneliness. Greater loneliness was associated with all domains of quality of life both cross-sectionally and longitudinally. Understanding factors associated with loneliness is critical to developing effective strategies at reducing loneliness and improving quality of life during the pandemic. Contrary to popular perceptions, older age was associated with less loneliness and more virtual social contact was associated with more loneliness. Thus, it may be prudent to deemphasize virtual social contact in public campaigns and to emphasize safe methods of interacting in person.

How price-gouging regulation undermined COVID-19 mitigation: county-level evidence of unintended consequences.

Despite long-standing criticisms, restrictions on price increases during emergencies remain widespread in the US. Criticisms most often cite the social costs of the shortages, but, we have found another, as yet unknown, cost: price-gouging regulations increased social contact during the onset of the COVID-19 pandemic. During the pandemic, thirty-four US states declared emergencies, which activated their preexisting price-gouging regulations, and eight others introduced new regulation along with their emergency declarations. Because these states border eight others that also declared emergencies, but had no price-gouging regulations, this created a unique natural experiment. Exploiting the pandemic-induced variation in regulation, and cellphone mobility data, we find that price controls increased visits to, and social contact in, commercial spaces, presumably because the regulation-induced shortages forced consumers to visit more stores and come in contact with more people as they struggled to find what they needed. This, of course, undermines social distancing efforts. Supplementary Information: The online version contains supplementary material available at 10.1007/s11127-023-01054-z.

The COVID-19 pandemic in various restriction policy scenarios based on the dynamic social contact rate.

The social contact rate has influenced the transmission of COVID-19, with more social contact resulting in more contagion cases. We chose 18 countries with the most confirmed cases in the first 200 days after the Wuhan lockdown. This was the first study using the dynamic social contact rate to simulate the epidemic under diverse restriction policies over 500 days since the COVID-19 outbreak. The developed General Dynamic Model suggested that the probability of contagion ranged from 12.52% to 39.39% in the epidemic. The geometric mean of the social contact rates differed from 18.21% to 96.00% between countries. The restriction policies in developed economies were 3.5 times more efficient than in developing economies. We compare the effectiveness of different policies for disease prevention and discuss the influence of policy adjustment frequency for each country. Maintaining the tightest restriction or alternate tightening and loosening restrictions was recommended, with each having an average 72.45% and 79.78% reduction in maximum active cases, respectively.

International students' collective resilience in crisis: Sense of community reduced anxiety via social contact and social support during lockdown.

Objectives: The role of community in individuals' well-being has been extensively examined in the Western context. However, little is known about how the host community is related to sojourners' well-being in a crisis in an Asian context. The current study aims at exploring international students' sense of community in the Chinese context under the direct threat of a global health crisis. Methods: Using a cross-sectional sample of 102 international students staying in Wuhan during the 76-day lockdown at the earliest stage of the COVID-19 pandemic, the current study explored the relationship between international students' sense of community and anxiety, and the mediating role of social contact, social support from three key sources in the host community (host university, international students, and Chinese friends). Results: Results showed that participants' stronger sense of community indirectly reduced anxiety via the role of sources of contact and support from the host community. Conclusions: This study provided further evidence to support the nurturance of the sense of community in community resilience and provided implications on how the host community can help to enhance sojourners' psychological well-being in a global crisis.

Participating in the digital world: a consensus statement on digital social contact for people with disabilities living in sheltered care facility homes

Introduction: Digital social contact is increasingly being used, which accelerated during the COVID-19 pandemic. This study aimed to determine the consensus among stakeholders regarding recommendations for the use and facilitation of digital social contact for people with intellectual disabilities living in sheltered care facility homes. Method(s): This consensus statement was developed in three consecutive rounds of questionnaires (rapid online modified Delphi design). The expert-groups included people with disabilities (N = 6) and their families (N = 10), support professionals (N = 9), behavioural consultants (N = 7), managers of sheltered care facility homes (N = 10), scientists and industry experts (N = 15). Finding(s): Four main themes were identified: 1. Reasons for and types of digital social contact;2. Support and training needs;3. Materials and other requirements needed to enable digital social contact;and 4. Best practices and future developments. For each theme, several recommendations were formulated. Discussion and conclusion: This study resulted in a consensus statement aimed mainly at care professionals, families of people with intellectual disabilities and managers of sheltered care facility homes. Findings show that digital social contact can contribute to societal participation of people with disabilities. Additionally, tailored exploration of digital contact is recommended, as well as aiming for inclusive-by-design technology developments with developers and stakeholders working together.Copyright © 2023 The Author(s).

Neighbourhood cohesion, loneliness and perceived social isolation prior and during the COVID-19 pandemic. Longitudinal evidence from the German Ageing Survey.

PURPOSE: To investigate the longitudinal association between neighbourhood cohesion and loneliness as well as perceived social isolation prior and during the COVID-19 pandemic (stratified by sex). METHODS: Longitudinal data were taken from a nationally representative sample (German Ageing Survey) of inhabitants aged 40 years and over in Germany prior (wave 6: year 2017) and during the COVID-19 pandemic (wave 8: November 2020 until February 2021; n = 6688 observations, mean age was 67.4 years). The De Jong Gierveld tool was used to measure loneliness and the Bude and Lantermann tool was used to measure perceived social isolation. Neighbourhood cohesion was assessed based on different items. RESULTS: FE regressions showed that decreases in closeness of contact with neighbours were associated with increases in loneliness and perceived social isolation levels among men, but not women. In contrast, decreases in different indicators of involvement in neighbourhood activities were associated with increases in loneliness and perceived social isolation levels among women, but not men. CONCLUSION: Changes in neighbourhood factors are differently associated with loneliness and perceived social isolation among middle-aged and older women and men. Gender-specific efforts to avoid loneliness and social isolation are, therefore, needed.

Estimating Changes in Contact Patterns in China Over the First Year of the COVID-19 Pandemic: Implications for SARS-CoV-2 Spread - Four Cities, China, 2020.

Introduction: Previous studies have demonstrated significant changes in social contacts during the first-wave coronavirus disease 2019 (COVID-19) in Chinese mainland. The purpose of this study was to quantify the time-varying contact patterns by age in Chinese mainland in 2020 and evaluate their impact on the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods: Diary-based contact surveys were performed for four periods: baseline (prior to 2020), outbreak (February 2020), post-lockdown (March-May 2020), and post-epidemic (September-November 2020). We built a Susceptible-Infected-Recovered (SIR) model to evaluate the effect of reducing contacts on transmission. Results: During the post-epidemic period, daily contacts resumed to 26.7%, 14.8%, 46.8%, and 44.2% of the pre-COVID levels in Wuhan, Shanghai, Shenzhen, and Changsha, respectively. This suggests a moderate risk of resurgence in Changsha, Shenzhen, and Wuhan, and a low risk in Shanghai. School closure alone was not enough to interrupt transmission of SARS-CoV-2 Omicron BA.5, but with the addition of a 75% reduction of contacts at the workplace, it could lead to a 16.8% reduction of the attack rate. To control an outbreak, concerted strategies that target schools, workplaces, and community contacts are needed. Discussion: Monitoring contact patterns by age is key to quantifying the risk of COVID-19 outbreaks and evaluating the impact of intervention strategies.

Together, at a distance: experiences with a novel technology for social contact among older people and their relatives in Norway during the COVID-19 pandemic.

BACKGROUND: The recognition that people are social beings is fundamental for person-centered care. During the COVID-19 pandemic, the lives of older people were restricted in ways that dramatically reduced their opportunities for face-to-face contact. Limited contact with family members due to social distancing raised concerns about the well-being of older people. In Norway, interactive technologies were therefore introduced to older people to help them maintain social contact while practicing physical distancing. OBJECTIVES: This study was designed to examine how older people and their relatives experienced the use of technology-mediated communication through KOMP, a tablet-like device for supporting social contact in care facilities and homes during the pandemic. METHODS: We adopted an open phenomenological approach inspired by Kvale and Brinkmann (2009) to explore how the use of KOMP became meaningful during the pandemic. The study was based on individual interviews with 4 residents in care facilities and 13 relatives. RESULTS: The lived experiences of using KOMP among older people and their relatives revealed that adopting digital communication helped older people, and their families mitigate social distancing and maintain relationships with each other, despite the restrictions imposed by the government. Virtual involvement through KOMP afforded meaningful interconnections in the social lives of the users and their distant family members, thereby supporting their roles as parents and grandparents despite the distance, and promoting cross-generational connections among family members. Digital meetings also provided opportunities for older people and their relatives to enjoy each other's presence in favored places, by conveying a homely atmosphere, for instance. These virtual encounters did not rely exclusively on talk as the only means of communication. CONCLUSION: This study suggests that communicating via KOMP was a meaningful activity for the participants. Technologies for social contact can, to some extent, facilitate person-centered care for older people in care facilities and their private homes, despite circumstances requiring social distancing.

Functions and relevance of spatial co-presence: Lessons learned from the COVID-19 pandemic for evidence-based workplace and human capital management

Introduction: This study aims to analyze the role of co-presence against the background of COVID-19 pandemic to derive implications for an interdisciplinary, evidence-based workplace and human capital management. A theoretical framework is outlined that considers a range of topics from task performance to social and organizational contextual factors. Methods: In a single organization qualitative case study, five focus group interviews including a total of 20 employees of an IT consultancy were conducted to identify the effects of the mandatory remote working regimes imposed by the COVID-19 Pandemic on task and contextual performance. Results: Findings show that individual performance was assessed to have increased while internal processes remained at similar levels compared to pre-pandemic levels. Organizational culture, social contact, and identity, however, were reported to have considerably deteriorated in the view of the participants. Discussion: The study shows that for a company that was very experienced with distributed working, the reduction of co-presence had important effects on performance and culture. Findings suggest that co-presence must be carefully managed in the future. This could become a new joint priority for workplace design, workplace management, and human capital management.

Quality of life in multiple scenarios: The impact of work mode and social contact quantity.

Introduction: During the COVID-19 pandemic, many employees were encouraged to temporarily work from home as an attempt to decrease social contact with others. However, the employees' quality of life (QoL) may have been threatened by this mode of working. This study, therefore, aims to explore the employees' QoL given the new mode of working from home (WFH) as a result of the pandemic vs. working in the office (WIO), the amount of social contact that they were exposed to, and the ratio of face-to-face contact that they had. Methods: A total of 803 WFH employees and 588 WIO employees' QoL was assessed during the same time period using the WHOQOL-BREF, which contains four domains: physical health, psychological health, social relationship, and the environment. We then divided the participants into 16 groups in accordance with the levels of work mode, social contact quantity, and face-to-face contact ratio-forming a case-control study. A differential item functioning (DIF) analysis was used to analyze the responses on the WHOQOL-BREF under the 4-dimensional rating scale model fitting. Results: The results indicated that WFH employees' QoL was superior to that of WIO employees. The relationship between the WFH mode and the employees' QoL was specifically moderated by the amount of social contact and the ratio of face-to-face contact that was experienced. The results further demonstrated that the increased amount of non-face-to-face contact was better for WFH employees' QoL than that of WIO employees. Discussion: In conclusion, the WFH mode was practical during the COVID-19 pandemic, as our findings indicated that WFH employees' QoL was better than WIO employees' QoL. However, maintaining social connections is equally important as this allows employees to perform better at their jobs and maintain such performance. The employees with a higher number of social support had a better QoL. Additionally, the facets detected as DIF items provided implications for the QoL with regard to the research methodology and insight into factors affecting the employees' QoL.

Call me maybe: Risk factors of impaired social contact during the COVID-19 pandemic and associations with well-being.

The COVID-19 pandemic caused major societal changes worldwide, with the most notable being lockdowns and restrictions on social contact. We conducted a longitudinal study (total n = 1907) in Germany with two time points to (1) identify demographic risk factors of impaired social contact during the pandemic, as well as investigate potential consequences of (2) impaired social contact and (3) different modes of communication on individuals' well-being during the first lockdown in spring 2020. Results indicate that particularly individuals living alone and being unable to work reported a lower frequency of (face-to-face) contact in comparison with participants living with others or working. Impaired social contact was indirectly associated with a negative development in well-being (life satisfaction, anxiety and depression) over time, and this relation was mediated via relatedness. Moreover, the frequency of face-to-face and phone communication during lockdown was positively associated with relatedness and well-being; however, digital communication was not. The findings stress the importance of maintaining social contact in times of social distancing and of fostering reconnection between individuals once the pandemic is over.

Comparing the effects of reduced social contact on psychosocial wellbeing before and during the COVID-19 pandemic: a longitudinal survey from two Norwegian counties.

PURPOSE: To determine changes to people's social contact during COVID-19, and whether reduced social contact was associated with changes to psychosocial wellbeing. METHODS: Questionnaire data were collected from a sample of adult respondents (18 years or more) in two Norwegian counties participating pre-COVID-19 (September 2019-February 2020; n = 20,196) and at two time points during COVID-19 (June [Mid] and November/December [Late] 2020; n = 11,953 and n = 10,968, respectively). The main outcome measures were participants' self-reported changes to social contact, loneliness, psychological distress, and life satisfaction. RESULTS: The proportion of respondents reporting less social contact due to COVID-19 decreased from 62% in Mid-2020 to 55% in Late-2020. Overall, reported psychological wellbeing remained unchanged or improved from pre-COVID-19 to Mid-2020. From Mid-2020 to Late-2020, however, a reduction in psychological wellbeing was observed. Poorer psychological wellbeing was found for those with less social contact during the pandemic compared with people reporting unchanged social contact. This effect increased over time and was observed for all age groups at Late-2020. At Mid-2020, the importance of change in social contact for change in psychological wellbeing was greatest among young adults (< 30 years), while no significant differences were found for the oldest age group. CONCLUSION: The association between COVID-19-era changes to social contact and loneliness, psychological distress, and life satisfaction is complex and appears to be age-dependent. Future studies should consider the quality of social contact and cultural contexts in which social restrictions are imposed.

Epidemic dynamics in census-calibrated modular contact network.

Network-based models are apt for understanding epidemic dynamics due to their inherent ability to model the heterogeneity of interactions in the contemporary world of intense human connectivity. We propose a framework to create a wire-frame that mimics the social contact network of the population in a geography by lacing it with demographic information. The framework results in a modular network with small-world topology that accommodates density variations and emulates human interactions in family, social, and work spaces. When loaded with suitable economic, social, and urban data shaping patterns of human connectance, the network emerges as a potent decision-making instrument for urban planners, demographers, and social scientists. We employ synthetic networks to experiment in a controlled environment and study the impact of zoning, density variations, and population mobility on the epidemic variables using a variant of the SEIR model. Our results reveal that these demographic factors have a characteristic influence on social contact patterns, manifesting as distinct epidemic dynamics. Subsequently, we present a real-world COVID-19 case study for three Indian states by creating corresponding surrogate social contact networks using available census data. The case study validates that the demography-laced modular contact network reduces errors in the estimates of epidemic variables.

Attachment, loneliness, and social connection as prospective predictors of suicidal ideation during the COVID-19 pandemic: A relational diathesis-stress experience sampling study.

INTRODUCTION: Concerns about the impact of the COVID-19 pandemic on mental health have led to efforts to understand how pandemic-specific factors, such as decreased social contact during periods of social distancing, may relate to suicide risk. The present study evaluated personality-based risk factors and frequency of social contact as prospective predictors of suicidal ideation (SI) during the pandemic. METHODS: We tested a relational diathesis-stress model of suicide focusing on insecure attachment, trait loneliness, and social contact as predictors of SI, using twice-weekly survey data collected via smartphone from a community sample (n = 184) over 8 weeks. RESULTS: Multilevel modeling showed that both trait loneliness and anxious attachment predicted the prospective development of SI during the study period. Reduced in-person contact, but not remote contact, was proximally associated with increased SI. Participants with high attachment avoidance were more likely to develop SI in the context of reduced daily in-person contact compared to participants without these traits. CONCLUSION: Findings support a relational diathesis-stress model of suicide risk during the pandemic, showing that dispositional traits related to emotional connection with others predicted the relative salience of reduced social contact as a proximal risk factor for SI.
