The DSM-5 dimensional model of personality disorder: rationale and empirical support

Ideally, a dimensional model of normal and abnormal personality functioning within the forthcoming DSM-5 would represent a common ground among the existing alternative models and would be consistent with the substantial body of empirical research that has accumulated on such models. The DSM-5 Work Group had the opportunity to make an historic step toward the integration of the normal personality traits researched within psychology with the personality disorders of psychiatry. They chose instead to construct a cumbersome six-dimensional model of personality disorder that excludes normal personality traits, is inconsistent with the preponderance of the research, and is distinguished explicitly from the predominant dimensional model of general personality structure.
