Background: Young people with eating disorders (EDs) and ED symptoms are at risk during university adjustment, suggesting a need to protect their health. The social identity approach proposes that people's social connections - and the identity-related behaviour they derive from them - are important for promoting positive health outcomes. However, there is a limited understanding as to how meaningful everyday connections, supported by affiliative identities, may act to reduce ED symptoms during a life transition.
Methods: Two hundred eighty-one first year university students with an ED or ED symptoms completed an online survey during the first month of university. Participants completed self-reported measures of affiliative identity, social support, injunctive norms and ED symptoms. Path analysis was used to test a hypothesised mediated model, whereby affiliative identity has a significant indirect relation with ED symptoms via social support and injunctive norms.
Results: Results support the hypothesised model. We show that affiliative identity predicts lower self-reported ED symptoms, because of its relation with social support and injunctive norms.
Conclusions: The findings imply that affiliative identities have a positive impact on ED symptoms during university adjustment, because the social support derived from affiliative identity is associated with how people perceive norms around disordered eating. Our discussion emphasises the possibility of identity processes being a social cure for those at risk of ED symptoms.
