title: Personality pathology is dimensional, so what shall we do with the DSM-IV personality disorder categories? The case of narcissistic personality disorder: Comment on Miller and Campbell (2010).
abstract: What is narcissism? Is it a dimensional personality trait? Is it the core element of a categorical form of psychopathology? Miller and Campbell (see record 2010-17135-004) present a thoughtful, scholarly, and well-written review of a substantial literature aimed at synthesizing research on trait narcissism and contemplating its relevance to the category of narcissistic personality disorder (NPD). They also present an argument that research on trait narcissism should be used to help propel research on NPD, as explicated in the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994). This latter argument is somewhat surprising in the context of the rest of Miller and Campbell's article and it is the focus of my commentary.
