The Core Emotion Framework (CEF) for Borderline Personality Disorder: A Critical Analysis and Mechanistic Comparison with Dialectical Behavior Therapy (DBT) and Schema Therapy (ST)

Borderline Personality Disorder (BPD) is defined by pervasive affective instability and chronic emotion dysregulation. This paper applies the Core Emotion Framework (CEF)—a structural‑constructivist model integrating affective neuroscience, embodied cognition, and strategic emotional regulation—to conceptualize BPD as a disorder of Emotional Rigidity, in which core emotions become maladaptively fused and lose their adaptive flexibility. CEF reframes BPD’s hypersensitivity, rapid affective shifts, and relational instability as failures in predictive emotional construction, driven primarily by an overwhelmed Sensing system and a rigid Achieving (Ego) structure. The framework is compared mechanistically with Dialectical Behavior Therapy (DBT) and Schema Therapy (ST): DBT targets behavioral skill deficits, ST targets maladaptive schemas and mode structures, while CEF intervenes at the moment‑to‑moment generation of emotion through conceptual restructuring, predictive updating, and detangling techniques. Although theoretically promising, CEF requires empirical validation, scale development, and open‑science trials before clinical adoption. The paper concludes with recommendations for cautious psychoeducational integration and a phased research agenda.
