Negative Affect as a Mediator Between Exposure to Fitspiration and Thinspiration and Disordered Eating Behaviors: An Ecological Momentary Assessment Study

Although social media use, such as Instagram, has been associated with ED pathology, mechanisms connecting social media use to disordered eating behaviors (DEBs) remain largely unevaluated. Based on Dual Process, Tripartite, and Affect Regulation models of ED pathology, we proposed a moderated mediation model evaluating impacts of exposure to fitspiration/thinspiration on Instagram.
