Diagnosing borderline personality. A pilot study using multiple diagnostic methods

Area of Science:

• Psychiatry
• Psychology
• Psychoanalysis

Background:

• Distinguishing personality organization levels (neurotic, borderline, psychotic) is crucial for treatment.
• Existing diagnostic methods may not fully capture the nuances of borderline personality organization.

Purpose of the Study:

• To introduce and validate a novel

Main Methods:

• Development of a "structural" interview focusing on here-and-now patient-interviewer dynamics.
• Assessment of three structural criteria: identity integration, defensive operations, and reality testing.
• Comparison of structural interview diagnoses with other methods (Gunderson's, psychological tests, clinical diagnoses) in 48 hospitalized patients.

Main Results:

• Substantial agreement was found between the structural interview and other diagnostic methods.
• The structural interview may identify a distinct dimension of personality functioning in borderline diagnoses.
• Borderline structural diagnoses align with severe character pathology, distinct from schizophrenic disorders.

Conclusions:

• The structural interview is a promising tool for personality disorder diagnosis and research.
• Its utility in differentiating borderline personality organization warrants further investigation.
• This approach may aid in understanding prognosis and treatment for severe character pathology.
