This study found minor links between borderline personality disorder (BPD) symptoms and response styles in personality assessments. Higher BPD symptoms were linked to less extreme responses, with some personality traits influencing BPD severity over time.
Area of Science:
- Psychology
- Psychiatry
- Personality Disorders
Background:
- Borderline personality disorder (BPD) involves dichotomous thinking and emotional processing biases.
- These characteristics may influence how individuals respond to personality assessment items.
- Understanding response styles is crucial for accurate BPD assessment.
Purpose of the Study:
- To investigate the association between self-reported BPD symptoms and response style biases.
- To examine how BPD symptoms relate to midpoint and extremity responding on the NEO Five Factor Inventory-3.
- To explore the longitudinal relationships between BPD symptoms and personality traits.
Main Methods:
- Item-response theory tree models were employed.
- Data from 2196 community participants (ages 18-20) in the Pittsburgh Girls Study were analyzed.
- Annual assessments over three years were utilized.
Main Results:
- Small to moderate negative correlations were found between BPD symptoms and midpoint responding.
- Small correlations were observed between BPD symptoms and extremity responding.
- Higher initial BPD symptoms correlated with decreased extraversion over time; low agreeableness was linked to increased BPD symptoms.
Conclusions:
- Response style biases showed small associations with BPD symptoms in a subthreshold sample.
- Personality traits like extraversion and agreeableness demonstrated longitudinal associations with BPD symptom severity.
- Findings suggest nuanced response patterns in individuals with subthreshold BPD symptoms.
