Cognitive therapy, originally conceived for the treatment of emotional
illnesses, has been successively used also in treating patients with
more severe mental disorders. In this article, the results obtained by
Shearin & Linehan (this volume) in a few controlled trials of dialect
ical behavior therapy in patients with borderline personality disorder
s are discussed. Differences between the treatment approach followed b
y Shearin and Linehan, which focuses on the modification of specific b
ehaviors, and that favored by the author, which is aimed at restructur
ing dysfunctional working models of self and environment, are highligh
ted. In the conclusion it is emphasized that the use of a structured,
didactic and cognitive-behaviorally oriented approach focused on perso
nal growth might represent an important and much wanted breakthrough i
n the treatment of the most disturbed patients with a borderline perso
nality disorder.
