Identifying as fat: Examining weight discrimination and the rejection-identification model

Discrimination towards fat individuals is pervasive in the United States, and perceptions of weight discrimination are associated with poor physical and mental health outcomes (e.g., low well-being). The rejection-identification model theorizes that perceptions of group-based discrimination may lead people to identify with their stigmatized group, subsequently helping them maintain well-being. We applied the rejection-identification model to weight discrimination to understand whether positively identifying as fat may mediate the impact of perceived weight-group discrimination on well-being. Across two samples (N = 739), fat-group identification, ingroup affiliation, and body affirmation were tested as mediators of the association between perceived weight discrimination and well-being. We also examined support for weight-related social change. Results showed that fat identification was a significant mediator, associated positively with discrimination but negatively with well-being; fat identification also was positively associated with greater support for weight-related social change. Body affirmation was a significant mediator of well-being and support for weight-related social change. Identifying as fat does not seem to provide the same benefits to well-being observed for other social identities (e.g., ethnicity); perceiving one's own body positively, however, may be a potential pathway through which weight discrimination's consequences can be reduced. Implications for well-being, identity, and the rejection-identification model are discussed. (c) 2022 Elsevier Ltd. All rights reserved.
