Relationships between borderline personality disorder features and client variables: Insights from variable- and...

Area of Science:

• Psychiatry
• Clinical Psychology
• Personality Disorders

Background:

• Borderline Personality Disorder (BPD) is a complex mental health condition with varied symptoms.
• Existing research often focuses on individual symptoms rather than broader patterns.

Purpose of the Study:

• To investigate the associations between specific BPD domains and pretreatment client characteristics.
• To identify distinct patient profiles within BPD using a person-centered approach.

Main Methods:

• Utilized both variable-centered and person-centered analyses on a sample of 801 university students and psychiatric outpatients.
• Employed the Five Factor Borderline Inventory-Short Form (FFBI-SF) and other psychological measures.
• Performed confirmatory factor analysis and latent profile analysis (LPA).

Main Results:

• The FFBI-SF confirmed a four-factor structure: Affective Dysregulation, Interpersonal Difficulties, Behavioral Dysregulation, and Identity Problems.
• Variable-centered analyses showed unique associations between BPD domains and client variables.
• LPA identified five distinct BPD profiles with significant differences in defense mechanisms, insight, interpersonal problems, and attachment styles.

Conclusions:

• Integrating variable- and person-centered approaches is crucial for understanding BPD's multidimensional nature.
• Recognizing domain-specific patterns and patient subgroups can inform tailored and effective BPD interventions.
