An empirically based classification of personality pathology: Where we are now and where do we go

The review of Sheets and Craighead (2007) affirms the lack of discriminant validity of the Diagnostic and Statistical Manual of Mental Disorders personality disorders, focusing in particular on the three clusters. They call for an empirically based, dimensional classification of personality disorder. Quite a bit of progress toward such an approach has occurred. This commentary emphasizes in particular the importance of having a dimensional model of personality disorder be integrated with general personality structure.
