Summary
Borderline personality disorder (BPD) may be a maladaptive variant of the 5-factor model (FFM) of personality. This study found the FFM borderline index strongly correlated with existing BPD measures and related dysfunction.
Area of Science:
- Psychology
- Psychiatry
- Personality Disorders
Background:
- Borderline personality disorder (BPD) is a complex mental health condition.
- Previous research suggests a link between BPD and broader personality traits.
Purpose of the Study:
- To test the hypothesis that BPD is a maladaptive variant of the 5-factor model (FFM) of personality.
- To develop and validate an FFM-based index for BPD.
Main Methods:
- Three independent samples were analyzed.
- An empirically derived FFM borderline profile was created.
- Individual FFM profiles were correlated with the borderline profile to create an FFM borderline index.
Main Results:
- The FFM borderline index showed high correlations with established BPD measures.
- The FFM borderline index correlated with measures of dysfunction, childhood abuse, and parental psychopathology.
- Results were consistent across all three samples.
Conclusions:
- Findings support the conceptualization of BPD as a maladaptive expression of FFM personality traits.
- The FFM borderline index serves as a valid measure for BPD and related correlates.
