After the worldwide outbreak of COVID-19 in 2020, many employees transitioned from in-office work to telework to slow down the spread of the virus. Building on the Job Demands-Resources model, we e...

In this article, we aim at theoretical specification and integration of mechanisms proposed within the Social Identity Approach to Health and Well‐being. We differentiate group‐level and individual‐level effects of shared social identity by distinguishing three different aspects: individual identification, group identification, and individually perceived group identification. We discuss specific group‐level mechanisms (i.e., mutual social support and collective self‐efficacy) and individual level‐mechanisms (i.e., attribution and appraisal processes regarding stressors and resources) for each of the three aspects. A core conclusion is that the positive effects of shared social identity on health and well‐being crucially depend on its close relationship with social support, and that although social support is an interindividual phenomenon, it is intraindividual mechanisms—attribution and appraisal—that shape the psychological partnership between social identity and social support. Therefore, we put special emphasis on cross‐level interactions between group‐ and individual‐level mechanisms, which have been widely neglected in earlier research.

Only recently has research begun to investigate the interplay between work characteristics, leisure time physical activity (LTPA), health, and well-being. So far, however, this research lacks a theoretical foundation. In this article, we introduce the physical activity-mediated Demand–Control (pamDC) model as a new theoretical framework. The two key ideas of the pamDC model are (1) that job demands and job control affect LTPA and (2) that LTPA partially mediates the effects of job demands and job control on health and well-being. We present eight propositions explaining how work characteristics affect LTPA, health, and well-being. For each of these propositions, we discuss empirical evidence and theoretical foundations. We then sketch a research agenda on how to adopt the pamDC model as a new theoretical framework for future research linking work characteristics, LTPA, and health. Finally, we discuss the practical implications of our new model.

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 N _T1 = 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.

It has been argued that the positive effect of a shared social identity on health and well‐being critically hinges on the interplay between social identity and social support. This interplay, however, is poorly understood. Building on Haslam et al., we argue that their relationship can be conceptualized as being reciprocal and dynamic with each variable influencing the other. The present study is the first to examine how the reciprocal relationship between social identification and perceived social support unfolds over time. In a sample of university freshmen ( N _T1 = 172), we examined this reciprocal relationship in a four‐wave survey study spanning over a period of 13 months. In line with Haslam et al., the results revealed a self‐reinforcing cycle with social identification at T1 being positively related to perceived social support at T2, which, in turn, was positively related to social identification at T3, which predicted perceived social support at T4. In conclusion, our study advances knowledge regarding the interplay between social identity and social support over time and, hence, contributes to our understanding of the mechanisms underlying the social cure effect.

It has been argued that, when they are acutely hungry, people act in self-protective ways by keeping resources to themselves rather than sharing them. In four studies, using experimental, quasi-experimental, and correlational designs (total N = 795), we examine the effects of acute hunger on prosociality in a wide variety of non-interdependent tasks (e.g. dictator game) and interdependent tasks (e.g. public goods games). While our procedures successfully increase subjective hunger and decrease blood glucose, we do not find significant effects of hunger on prosociality. This is true for both decisions incentivized with money and with food. Meta-analysis across all tasks reveals a very small effect of hunger on prosociality in non-interdependent tasks (d = 0.108), and a non-significant effect in interdependent tasks (d = −0.076). In study five (N = 197), we show that, in stark contrast to our empirical findings, people hold strong lay theories that hunger undermines prosociality.
