Dependency, mood instability, and inconsequence traits for discriminating borderline personality disorder

Area of Science:

• Psychiatry
• Clinical Psychology
• Personality Disorders

Background:

• Borderline Personality Disorder (BPD) is a widely studied personality disorder.
• BPD is characterized by emotional lability, anxiety, impulsiveness, and hostility.
• Key affected domains include negative affectivity and antagonism.

Purpose of the Study:

• Investigate discriminant dimensions of the Dimensional Clinical Personality Inventory (IDCP-2).
• Distinguish individuals with BPD from those without the diagnosis.
• Identify key BPD traits using the IDCP-2.

Main Methods:

• Study included 305 participants: 30 with BPD, 75 with other PDs, and 200 from the community.
• Assessed BPD traits using dependency, mood instability, and inconsequence dimensions of the IDCP-2.
• Utilized analysis of variance (ANOVA) and multiple regression analysis.

Main Results:

• The BPD group showed highest mean measures on IDCP-2 dimensions.
• Mood instability factors were most discriminant across all groups.
• Hopelessness emerged as the most predictive measure (adjusted r² = 0.50).

Conclusions:

• The IDCP-2 dimensions demonstrated discriminatory capacity for BPD.
• Results were more consistent in discriminating BPD from the general community sample.
• Mood instability and hopelessness are significant indicators for BPD identification.
