Personality traits in the DSM-5.

Recent advances in personality research coupled with a broad acknowledgment of the limitations of the representation of personality pathology in the third and fourth editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III and DSM-IV) have positioned personality science to influence the shape of personality assessment in the fifth edition (DSM-5). Representing normative personality with well-validated traits that are broad, normally distributed, theoretically integrative, and distinct from personality disorder constructs would take optimal advantage of this opportunity. The assessment of normative traits would also link a large body of personality research with the practice of clinical diagnosis and would encourage clinicians to consider every patient's personality regardless of his or her diagnosis. Furthermore, conceptualizing personality traits and disorders separately would promote more careful clinical consideration of the functional severity and specific symptom constellations among personality disorders. Based on these considerations I argue that Five-factor model personality traits should be assessed separately from personality disorders in the DSM-5.
