Reduced loneliness mediates the effects of multiple group identifications on well-being.

Membership of multiple groups and identification with those groups have been found to be positively related to individuals' health and well-being. The present research sought to replicate this finding in two large, representative samples. Moreover, we sought to extend previous work by shedding light on the mechanisms mediating the effects of multiple group membership on positive health outcomes. Specifically, we proposed that the links between multiple group membership and positive health outcomes are mediated by reduced feelings of loneliness. In Study 1, a two-wave survey of a German population, participants (N = 989) were asked about their identification with family, friends, neighbourhood, their country and humanity and 4 weeks later about feelings of loneliness, physical health and stress. As hypothesized, multiple identifications predicted lower stress. They were also associated with a marginal reduction in physical symptoms of poor health. Both relationships were mediated by the absence of loneliness. In Study 2, we conducted a cross-sectional survey of German participants (N = 1635), which also included a sixth target of identification (Europe). Results replicated findings from Study 1 and also found similar relations associated with smaller (family, friends and neighbourhood) versus larger (country, Europe and Humanity) foci of identification.

An examination and extension of the Peltzman effect during the Covid-19 pandemic.

Since the first COVID-19 case was confirmed in Germany, the German government has introduced various measures to counteract the pandemic. The implementation of safety measures can have counterproductive effects: people engage in risk compensatory behavior (fewer safety behaviors) after regulations are introduced and obligated by the government, which is known as the Peltzman effect (Peltzman, 1975). Based on the Peltzman effect, the researchers of this study hypothesized that people complied less with safety behaviors and took more health risks (e.g. keep less distance) after the implementation of more stringent COVID-19-related regulations (quarantine obligation and face mask duty) between the two measurement periods of this study. They also extended the Peltzman model by hypothesizing moderating roles of age, gender, and perceived COVID-19 threat. Results of the longitudinal survey study (N = 989, T1: 26 March - 31 March 2020 and T2: 27 April - 4 May 2020) confirm that people indeed complied less with safety recommendations over time associated with strengthened COVID-19-related regulations. Perceived COVID-19 threat to those in a person's surroundings (e.g. family, neighbors) had a positive impact on compliance, but age and gender had no effect. This extends the literature on the Peltzman effect by adding perceived COVID-19 threat as a new relevant construct, enabling the development of more effective safety preventions in the future.

Team identification relates to lower burnout-Emotional and instrumental support as two different social cure mechanisms.

Team identification is associated with less exhaustion and disengagement through more social support and higher collective self-efficacy. However, previous studies did not distinguish between emotional and instrumental support, even though both forms of support may relate differently to collective self-efficacy. By distinguishing between both support forms, we expected an indirect effect-the 'supportive structure' mechanism-of team identification on burnout mediated via emotional support. For a second mechanism-the 'supportive action' mechanism-we expected an indirect effect serially mediated by instrumental support and collective self-efficacy. We tested our hypotheses among NT1  = 567 employees in a four-wave study with 3-month time lags between measurement points. Partially in line with our expectations, emotional support (T2) mediated the relation between team identification (T1) and disengagement (T4), but not emotional exhaustion (T4). Moreover, as expected, the results showed an indirect association between team identification (T1) and emotional exhaustion and disengagement (T4) via instrumental support (T2) and collective self-efficacy (T3). Accordingly, employees benefit from both support forms but through different mechanisms. We discuss our findings and implications for future research.

Effects of general and corona-specific stressors on mental burden during the SARS-CoV-2 pandemic in Germany.

The SARS-CoV-2 pandemic turned out to be a serious threat to mental and physical health. However, the relative contribution of corona-specific (DHs) and general stressors (DHg) on mental burden, and specific protective and risk factors for mental health are still not well understood. In a representative sample (N = 3,055) of the German adult population, mental health, potential risk, and protective factors as well as DHs and DHg exposure were assessed online during the SARS-CoV-2 pandemic (June and July 2020). The impact of these factors on mental health was analyzed using descriptive statistics, data visualizations, multiple regressions, and moderation analyses. The most burdensome DHg were financial and sleeping problems, respectively, and DHs corona-media reports and exclusion from recreational activities/important social events. 31 and 24% of total mental health was explained by DHg and DHs, respectively. Both predictors combined explained 36%, resulting in an increase in variance due to DHs of only 5% (R2 adjusted). Being female, older and a lower educational level were identified as general risk factors, somatic diseases as a corona-specific risk factor, and self-efficacy and locus of control (LOC) proved to be corona-specific protective factors. Further analyses showed that older age and being diagnosed with a somatic illness attenuated the positive influence of LOC, self-efficacy, and social support on resilience. Although the data showed that after the first easing restrictions, the stressor load was comparable to pre-pandemic data (with DHs not making a significant contribution), different risk and protective factors could be identified for general and corona-specific stressors. In line with observations from network analysis from other groups, the positive impact of resilience factors was especially diminished in the most vulnerable groups (elderly and somatically ill). This highlights the need to especially target these vulnerable groups to foster their resilience in upcoming waves of the corona pandemic.

Sweet as Sugar-How Shared Social Identities Help Patients in Coping with Diabetes Mellitus.

Social identification is health-beneficial as social groups provide social support (i.e., the social cure effect). We study this social cure effect in diabetes patients by focusing on two relevant sources of social support, namely medical practitioners (MP) and fellow patients. As both groups have diabetes-specific knowledge, we predict that sharing an identity with them provides access to specific support, which, in turn, optimizes individuals' diabetes management and reduces diabetes-related stress. We further predict that identifying with their MP or fellow patients will be more strongly related to perceived social support among individuals with lower diabetes-specific resilience because they pay more attention to supportive cues. We tested this moderated mediation model in a two-wave study with n = 200 diabetes patients. Identification with the MP related to more support, which, in turn, was related to better diabetes management and less diabetes-specific stress. Identification with fellow patients related to more support; however, social support was unrelated to diabetes management and stress. Resilience only moderated the relationship between MP identification and support, as people with lower resilience levels reported more support from their MP. This study shows the importance of social identification with the MP and other diabetes patients, especially for people with lower resilience levels.

How national leaders keep 'us' safe: A longitudinal, four-nation study exploring the role of identity leadership as a predictor of adherence to COVID-19 non-pharmaceutical interventions.

OBJECTIVES: To investigate whether citizens' adherence to health-protective non-pharmaceutical interventions (NPIs) during the COVID-19 pandemic is predicted by identity leadership, wherein leaders are perceived to create a sense of shared national identity. DESIGN: Observational two-wave study. Hypotheses testing was conducted with structural equation modelling. SETTING: Data collection during the COVID-19 pandemic in China, Germany, Israel and the USA in April/May 2020 and four weeks later. PARTICIPANTS: Adults in China (n=548, 66.6% women), Germany (n=182, 78% women), Israel (n=198, 51.0% women) and the USA (n=108, 58.3% women). MEASURES: Identity leadership (assessed by the four-item Identity Leadership Inventory Short-Form) at Time 1, perceived shared national identification (PSNI; assessed with four items) and adherence to health-protective NPIs (assessed with 10 items that describe different health-protective interventions; for example, wearing face masks) at Time 2. RESULTS: Identity leadership was positively associated with PSNI (95% CI 0.11 to 0.30, p<0.001) in all countries. This, in turn, was related to more adherence to health-protective NPIs in all countries (95% CI 0.03 to 0.36, 0.001≤p≤0.017) except Israel (95% CI -0.03 to 0.27, p=0.119). In Germany, the more people saw Chancellor Merkel as engaging in identity leadership, the more they adhered to health-protective NPIs (95% CI 0.04 to 0.18, p=0.002). In the USA, in contrast, the more people perceived President Trump as engaging in identity leadership, the less they adhered to health-protective NPIs (95% CI -0.17 to -0.04, p=0.002). CONCLUSIONS: National leaders can make a difference by promoting a sense of shared identity among their citizens because people are more inclined to follow health-protective NPIs to the extent that they feel part of a united 'us'. However, the content of identity leadership (perceptions of what it means to be a nation's citizen) is essential, because this can also encourage people to disregard such recommendations.

Perceptions of the Targets and Sources of COVID-19 Threat are Structured by Group Memberships and Responses are Influenced by Identification with Humankind.

The purpose of this study was to investigate which social groups are perceived as a threat target and which are perceived as a threat source during the COVID-19 outbreak. In a German sample (N = 1454) we examined perceptions of social groups ranging from those that are psychologically close and smaller (family, friends, neighbors) to those that are more distal and larger (people living in Germany, humankind). We hypothesized that psychologically closer groups would be perceived as less affected by COVID-19 as well as less threatening than more psychologically distal groups. Based on social identity theorizing, we also hypothesized that stronger identification with humankind would change these patterns. Furthermore, we explored how these threat perceptions relate to adherence to COVID-19 health guidelines. In line with our hypotheses, latent random-slope modelling revealed that psychologically distal and larger groups were perceived as more affected by COVID-19 and as more threatening than psychologically closer and smaller groups. Including identification with humankind as a predictor into the threat target model resulted in a steeper increase in threat target perception patterns, whereas identification with humankind did not predict differences in threat source perceptions. Additionally, an increase in threat source perceptions across social groups was associated with more adherence to health guidelines, whereas an increase in threat target perceptions was not. We fully replicated these findings in a subgroup from the original sample (N = 989) four weeks later. We argue that societal recovery from this and other crises will be supported by an inclusive approach informed by a sense of our common identity as human beings.

A trouble shared is a trouble halved: The role of family identification and identification with humankind in well-being during the COVID-19 pandemic.

The COVID-19 pandemic has triggered health-related anxiety in ways that undermine peoples' mental and physical health. Contextual factors such as living in a high-risk area might further increase the risk of health deterioration. Based on the Social Identity Approach, we argue that social identities can not only be local that are characterized by social interactions, but also be global that are characterized by a symbolic sense of togetherness and that both of these can be a basis for health. In line with these ideas, we tested how identification with one's family and with humankind relates to stress and physical symptoms while experiencing health-related anxiety and being exposed to contextual risk factors. We tested our assumptions in a representative sample (N = 974) two-wave survey study with a 4-week time lag. The results show that anxiety at Time 1 was positively related to stress and physical symptoms at Time 2. Feeling exposed to risk factors related to lower physical health, but was unrelated to stress. Family identification and identification with humankind were both negatively associated with subsequent stress and family identification was negatively associated with subsequent physical symptoms. These findings suggest that for social identities to be beneficial for mental health, they can be embodied as well as symbolic.
