Since the 2001 publication of APA's Practice
Guideline for the Treatment of Patients With Borderline Personality
Disorder (1), more studies have been published
on borderline personality disorder (BPD) than on any other personality
disorder (2, 3). New analyses of the validity of the DSM-IV-TR criteriadefined
construct of BPD have been published, new data on the prevalence
of BPD are available, risk factors for and biological characteristics
of BPD are being elucidated, and new studies on the treatment of
BPD have been carried out. This guideline watch highlights the most
important of these developments.
