Cognitive features of borderline personality disorder
MC Zanarini, JG Gunderson and FR Frankenburg
Psychosocial Research Program, McLean Hospital, Belmont, MA 02173.
Of 50 patients with borderline personality disorder, 100% reported
disturbed but nonpsychotic thought, 40% (N = 20) reported quasi- psychotic
thought, and none reported true psychotic thought during the past 2 years;
only 14% (N = 7) reported ever experiencing true psychotic thought.
Disturbed and quasi-psychotic thought was significantly more common among
these patients than among patients with other axis II disorders or
schizophrenia and normal control subjects; however, true psychotic thought
was significantly more common among schizophrenic patients. While disturbed
thought was also common among axis II disorder and schizophrenic patients,
quasi-psychotic thought was reported by only one of these subjects,
suggesting that quasi- psychotic thought may be a marker for borderline
personality disorder.
