This video is a review of the empirical data that concludes we have been wrong about personality pathology when it comes to the etiology or cause of personality disorders. It is most often assumed that early childhood trauma or adversity in childhood is the main cause of the development of personality disorders. However, contrary to popular belief, research in neuroscience, neurobiology, family, twin, and adoption studies, behavioral genetics, and neuroimaging findings, have challenged and discredited the myth that personality disorders are caused by childhood adversity and trauma. Research now shows that personality disorders are highly heritable, and the environmental influence on these genetically predisposed disorders has nothing to do with family upbringing or parenting style, surprisingly. At this point in time, trauma and abuse in childhood, based on the hard data, is no more than a nonessential risk factor when it comes to personality disorders.
