      Wynn, Rolf; Høiseth, Marita; Pettersen, Gunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Prior research on psychopathy has primarily focused on the problem in men. Only a few studies have examined whether psychopathy even exists in women, and if so, how the disorder manifests itself in them. This paper presents a narrative review of the literature on gender and psychopathy. We briefly discuss why this is an important topic for women and we discuss its causes. The concept of psychopathy ...
