Causal Pathways

Borderline personality disorder (BPD) is characterized by impulsivity, emotion dysregulation, disturbed relationships, and identity disturbances. Despite the known variable co-occurrence of BPD symptoms, the possible causal relationships are not well understood. We addressed this by creating a hierarchical network model of BPD, which identifies the most likely acyclic causal pathways that are driving BPD development. Cross-sectional data was obtained from the Structured Clinical Interview-II (SCID-II), and possible causal relationships between symptoms were identified from conditional independence relations. The symptoms’ hierarchy values, assessing their role in causal pathways, was determined by a random walk-based algorithm. By analyzing the directed network of BPD symptoms, it was found that symptoms in initial stages of causal pathways were abandonment, physical fights, impulsivity, suicidal threats, identity disturbances, and affective instability. Based on the assessed role symptoms play in causal pathways of BPD development, specific symptoms can be targeted during early diagnosis and clinical assessment.
