Connecting to Community: A Social Identity Approach to Neighborhood Mental Health.

ACADEMIC ABSTRACT: Integrative theorizing is needed to advance our understanding of the relationship between where a person lives and their mental health. To this end, we introduce a social identity model that provides an integrated explanation of the ways in which social-psychological processes mediate and moderate the links between neighborhood and mental health. In developing this model, we first review existing models that are derived primarily from a resource-availability perspective informed by research in social epidemiology, health geography, and urban sociology. Building on these, the social identity model implicates neighborhood identification in four key pathways between residents' local environment and their mental health. We review a wealth of recent research that supports this model and which speaks to its capacity to integrate and extend insights from established models. We also explore the implications of the social identity approach for policy and intervention. PUBLIC ABSTRACT: We need to understand the connection between where people live and their mental health better than we do. This article helps us do this by presenting an integrated model of the way that social and psychological factors affect the relationship between someone's neighborhood and their mental health. This model builds on insights from social epidemiology, health geography, and urban sociology. Its distinct and novel contribution is to point to the importance of four pathways through which neighborhood identification shapes residents' mental health. A large body of recent research supports this model and highlights its potential to integrate and expand upon existing theories. We also discuss how our model can inform policies and interventions that seek to improve mental health outcomes in communities.

The fish can rot from the heart, not just the head: Exploring the detrimental impact of transgressions by leaders at multiple levels of an organization.

In this registered report, we examined the effect of transgressions committed by leaders working at different group levels within an organization on employee outcomes. Based on social identity theorizing, we argued that organizational leader transgressions would affect organizational members' experiences only at the organizational level, but that workgroup leader transgressions would impact organizational members' experiences at both workgroup and organizational levels. To test these ideas, we developed a 2 (leader group affiliation: workgroup vs. organizational) × 2 (leader behaviour: normative vs. transgressive) between-subjects experimental paradigm. As hypothesized, both workgroup and organizational leader transgressions resulted in decreased organizational identification and perceived organizational leader effectiveness. Contrary to our prediction, transgressions of both workgroup and organizational leaders were similarly detrimental to workers' workgroup identification. However, as predicted, a transgressive workgroup leader had a greater negative impact on perceived workgroup leader effectiveness than a transgressive organizational leader. When outliers were excluded, a workgroup leader's transgression was found to be more detrimental to work performance than an organizational leader's transgression. Overall, this study demonstrates that the transgressions of lower-level workgroup leaders can be as detrimental - and in some cases more detrimental - to workers than the transgressions of higher-level organizational leaders.

A community-led intervention to build neighbourhood identification predicts better wellbeing following prolonged COVID-19 lockdowns.

Introduction: A growing body of research supports the importance of social cohesion for population wellbeing. However, the majority of this research has been correlational, and rarely have interventions been evaluated. Method: We conducted a two-timepoint study investigating the role of Neighbour Day, a grass-roots, community-led intervention that seeks to build social cohesion across the population. Among a sample of 843, 125 were Neighbour Day participants while the remainder were not. Results: We found that, compared to non-participants, Neighbour Day participants had significantly higher neighbourhood identification, experienced greater social cohesion, and had larger neighbourhood social networks. Between timepoints, the majority of the sample experienced prolonged lockdowns to prevent COVID-19 transmission, and so unsurprisingly, wellbeing declined and psychological distress increased. However, Neighbour Day participants were protected against these negative mental health effects of lockdown. These benefits of Neighbour Day participation were mediated via neighbourhood identification. Discussion: Overall, the findings speak to the promise of large-scale interventions to build social identity, particularly due to their capacity to build resilience and protect people's wellbeing during times of collective change or crisis.

Social identity makes group-based social connection possible: Implications for loneliness and mental health.

This review argues that a distinctly positive form of social connection is made possible by the social identities that people derive from psychologically meaningful group memberships. These connections have important implications for mental health by virtue of their distinct capacity to furnish people with a sense of collective meaning, purpose, support, and efficacy. This analysis suggests that loneliness and its toxic effects arise in part from the challenges of achieving this distinct form of social connection in contemporary society. However, it also suggests that a good way to tackle loneliness and support mental health is by building, restoring, and sustaining social identities through meaningful group-based connections. We conclude by reflecting on the success of interventions that do precisely this - most notably Groups 4 Health.

Perceived COVID-19 risk is attenuated by ingroup trust: evidence from three empirical studies.

BACKGROUND: The social identity model of risk taking proposes that people take more risks with ingroup members because they trust them more. While this can be beneficial in some circumstances, in the context of the COVID-19 pandemic it has the potential to undermine an effective public health response if people underestimate the risk of contagion posed by ingroup members, or overestimate the risk of vaccines or treatments developed by outgroup members. METHODS: Three studies (two prospective surveys, one experiment) with community-based adults tested the potential for the social identity model of risk taking to explain risk perception and risk taking in the context of COVID-19. RESULTS: Study 1 was a two-wave study with a pre-COVID baseline, and found that people who identified more strongly as a member of their neighborhood pre-COVID tended to trust their neighbors more, and perceive interacting with them during COVID-19 lockdown to be less risky. Study 2 (N = 2033) replicated these findings in a two-wave nationally representative Australian sample. Study 3 (N = 216) was a pre-registered experiment which found that people indicated greater willingness to take a vaccine, and perceived it to be less risky, when it was developed by an ingroup compared to an outgroup source. We interpret this as evidence that the tendency to trust ingroup members more could be harnessed to enhance the COVID-19 response. CONCLUSIONS: Across all three studies, ingroup members were trusted more and were perceived to pose less health risk. These findings are discussed with a focus on how group processes can be more effectively incorporated into public health policy, both for the current pandemic and for future contagious disease threats.

Evidence that loneliness can be reduced by a whole-of-community intervention to increase neighbourhood identification.

RATIONALE: Social identification with the people in one's neighbourhood has a wide variety of benefits for individual and community health and wellbeing. In particular, previous research shows that residents' social identification with their neighbourhood is protective of mental health. However, researchers are only just beginning to design and evaluate interventions that directly target social identification on health grounds. OBJECTIVE: This longitudinal study evaluated a whole-of-community intervention at scale (Neighbour Day, 2019), in which Australian residents were encouraged to build social connections in their local community. Neighbour Day is a campaign that seeks to raise public awareness of the importance of connecting with neighbours and had a reach of approximately 300,000 people in 2019. METHODS: Participants were 437 hosts of neighbourhood events held across 276 diverse suburbs across Australia. Participants were surveyed at three-time points; before and after Neighbour Day, as well as at six-month follow up. RESULTS: Hosting a Neighbour Day event led to a significant increase in neighbourhood social identification, which was sustained six months later. This increase in social identification predicted increased social cohesion, reduced loneliness and improved wellbeing. CONCLUSIONS: This study provides evidence that neighbourhood identification is an effective target mechanism to curb loneliness and social fragmentation in the community. Implications are discussed with a focus on how social identity-building interventions can be effectively implemented in community settings to benefit public health.

Friendships that money can buy: financial security protects health in retirement by enabling social connectedness.

BACKGROUND: Research on the health and wellbeing of retirees has tended to focus on financial security and financial planning. However, we suggest that one reason why financial security is important for retirees is that it enables social connectedness, which is critical for healthy ageing. METHODS: This paper tests this hypothesis cross-sectionally (N = 3109) and longitudinally (N = 404) using a population-weighted mixed effects mediation model in two nationally representative samples of Australian retirees. RESULTS: Analyses provide robust support for our model. Subjective financial security predicted retiree health cross-sectionally and longitudinally. Social connectedness also consistently predicted mental health and physical health, on average four times more strongly than financial security. Furthermore, social connectedness partially accounted for the protective effect of subjective financial security. CONCLUSIONS: We discuss the implications of these findings for public health, with a particular emphasis on how social connectedness can be better supported for people transitioning to retirement.

Neighbourhood identification buffers the effects of (de-)gentrification and personal socioeconomic position on mental health.

Previous studies have suggested that the effects of gentrification on long-term residents' mental health depends upon individual socioeconomic position. However, the role of social psychological moderators of these effects remains unexplored. Drawing on the social identity approach to health, we examine whether social identification with the neighbourhood can be protective of mental health for residents in the context of (de-)gentrification. Using multi-level modelling in a longitudinal Australian sample (N = 8376), we show that neighbourhood identification protects the mental health of residents who live in neighbourhoods that undergo positive or negative neighbourhood socioeconomic status change.
