Problems with the DSM-IV-TR Categories

Symptoms described are often only extreme versions of
otherwise “normal” traits.

Overlap in the diagnostic criteria and the majority of people who
are diagnosed with one disorder tend to meet the diagnostic
criteria for at least one other personality disorder.

Diagnosing a personality disorder often requires information
that is hard for a clinician to obtain.

Conceptualized as stable characteristics, yet they vary, so
individuals go in and out of the diagnosis
