The relationship between comorbid personality disorders and treatment received in patients with anxiety disorders.
Few studies have addressed the relationship between the presence of a comorbid personality disorder and the amount of psychiatric treatment received by patients with an Axis I disorder. This issue has not been studied in patients with anxiety disorders. In a prospective, naturalistic, longitudinal study of anxiety disorders, 526 subjects were assessed with the Personality Disorder Examination, and types of treatment received in 1991 and 1996 were identified. In 1991, compared to subjects without a personality disorder, subjects with a personality disorder were as likely to receive medication and they received a greater number of medications. Subjects with borderline personality disorder were more likely to receive heterocyclic antidepressants and interventions characteristic of psychodynamic psychotherapy and cognitive therapy; they also reported receiving a greater number of medications and types of psychosocial treatment than other subjects. In 1996, subjects with borderline personality disorder were more likely to receive psychodynamic interventions. These findings suggest that in patients with an anxiety disorder, the presence of a comorbid personality disorder is associated with receiving a greater number of medications but not with a greater likelihood of receiving pharmacologic or psychosocial treatment. However, the presence of borderline personality disorder is associated with a greater likelihood of receiving, and receiving a greater number of, certain types of somatic and psychosocial treatments.
