Social support plays a critical role in supporting the help-seeking and recovery process for people with disordered eating.1 Yet, social connections are often not supportive for this population, who instead experience high levels of loneliness and stigma that hinder recovery. Previous research has predominantly focused on determinants of disordered eating that reside within the individual (e.g., thin ideal internalisation, personality traits)3, with decidedly less attention given to social determinants. This co-designed study uses a three-wave longitudinal survey design with Australian adults to investigate the role of social connection and support, stigma, and disordered eating norms in help-seeking and experiences of disordered eating symptoms.
