Treating the "mischances of character," simply and effectively

Cluster B personality disorders, particularly borderline personality disorder (BPD) and narcissistic personality disorder (NPD), are simultaneously among the most disruptive and impairing and among the least well studied, especially regarding treatment. In this paper we present an approach to treating these disorders that emphasizes motivation for treatment, self-control, and a highly structured way to reduce personality disorder symptomatology. Initial testing of the approach on nine patients with BPD and six patients with NPD indicates promise. Case reports are used to illustrate the approach.
