    • Defining compulsive exercise in eating disorders: acknowledging the exercise paradox and exercise obsessions 

      Bratland-Sanda, Solfrid; Mathisen, Therese Fostervold; Sundgot-Borgen, Jorunn; Rosenvinge, Jan H (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-04)
      Recently Dittmer et al. (JED 6:1–9, 2018). suggested a transdiagnostic definition and a clinical assessment for compulsive exercise in adolescents and adults with eating disorders. In this letter to the editor, we extend the transdiagnostic bridge to the DSM-5-criteria for obsessive-compulsive disorders and hence raise the issue of exercise obsession without compulsive exercise actions. We argue ...
