Drs. Shedler and Westen suggested that the constructs assessed by the 12 SWAP-200 scales are outside of the realm of the five-factor model. They ignored many, many studies that indicated otherwise. For example, two other compelling dimensional models of personality disorder have been developed by Dr. Livesley (the Dimensional Assessment of Personality Pathology) and Dr. Clark (the Schedule for Nonadaptive and Adaptive Personality). A complete description of and references for these measures, as well as others, is provided by Widiger and Simonsen (2). The clinical constructs assessed by these scales include narcissism, identity problems, eccentric perceptions, affective lability, aggression, detachment, self-harm behaviors, and compulsivity that resemble closely the scales of the SWAP-200, and many studies have documented well that the constructs assessed by the Dimensional Assessment of Personality Pathology and the Schedule for Nonadaptive and Adaptive Personality are well within the realm of the five-factor model.
