The Social Identity approach to stress has shown how intragroup support processes shape individuals’ responses to stress across healthcare, workplace and community settings. However the issue of how these ‘Social Cure’ processes can help cope with the stress of intergroup contact has yet to be explored. This is particularly important given the pivotal role of intergroup threat and anxiety in the experience of contact as well as the effect of contact on extending the boundaries of group inclusion. The present study applies this perspective to a real-life instance of residential contact in a divided society. Semi-structured interviews with 14 Catholic and 13 Protestant new residents of increasingly mixed areas of Belfast city, Northern Ireland, were thematically analysed. Results highlight that transitioning to mixed communities was fraught with intergroup anxiety, especially for those coming from ‘single-identity’ areas. Help from existing residents, especially when offered by members of other religious denominations, signalled a ‘mixed community ethos’ to new residents which facilitated adopting and sharing this identity. This shared identity then enabled them to deal with unexpected intergroup threats and provided resilience to future sectarian division. New residents who did not adopt this shared identity remained isolated, fearful and prone to negative contact.
