Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Personality Disorders

Background:

  • Differentiating borderline personality disorder (BPD) from bipolar I disorder (BD) presents diagnostic challenges.
  • Shared symptoms necessitate evaluation of personality functioning, self-identity, and interpersonal relations for accurate differential diagnosis.

Purpose of the Study:

  • To empirically investigate and compare personality organization (PO), identity integration, and object relations in patients with BPD and BD.
  • To identify key differences in personality functioning that aid in distinguishing between BPD and BD.

Main Methods:

  • Utilized the Structured Interview of Personality Organization (STIPO) and Level of Personality Functioning Scale (LPFS).
  • Assessed 34 BPD patients, 28 BD patients, and 27 healthy controls.
  • Employed group comparisons and logistic regression to analyze differences.

Main Results:

  • BPD patients showed significantly greater impairment in identity and aggression domains, with less impairment in moral values.
  • The overall level of PO was significantly lower in the BPD group, even when excluding other personality disorders in the BD sample.
  • Impaired personality structure severity impacted symptom load independently of the primary diagnosis (BPD or BD).

Conclusions:

  • BPD is characterized by severe deficits in PO, whereas BD patients exhibit more variable PO levels.
  • Greater impairment in personality functioning is evident in BPD compared to BD.
  • Assessing PO is crucial for differential diagnosis and effective treatment planning in both BPD and BD.
