ResearchPod Summary
Borderline Personality Disorder (BPD) is frequently characterized as a disorder of dysregulation. While this term is often applied broadly to interpersonal, behavioral, and cognitive domains, emotion dysregulation is widely considered the core pathology. This paper organizes the complex, multifaceted nature of emotion dysregulation in BPD into a four-component process based on Linehan’s biosocial theory: emotion sensitivity, heightened and labile negative affect, a deficit of appropriate regulation strategies, and a surplus of maladaptive regulation strategies.
Emotion Sensitivity: Individuals with BPD are theorized to possess a biological predisposition toward heightened reactivity to environmental stimuli, particularly those with negative emotional valence. Research indicates a cognitive bias toward identifying negative emotions in others, often accompanied by difficulties in accurately recognizing facial expressions.
Heightened and Labile Negative Affect: This component involves both the intensity of negative emotions and their instability over time. Using intensive longitudinal data and ecological momentary assessment (EMA), studies have shown that BPD patients experience rapid, unpredictable shifts in mood, often triggered by subtle environmental events.
Deficit of Appropriate Regulation Strategies: Beyond experiencing intense emotions, individuals with BPD often lack the skills to manage them effectively. This includes lower emotional awareness and poor "emotional granularity"—the ability to differentiate between specific emotional states. Research suggests that an inability to tolerate distress is a significant barrier to employing adaptive coping mechanisms.
Surplus of Maladaptive Regulation Strategies: When adaptive strategies fail, individuals often turn to maladaptive behaviors to reduce aversive emotional states. This includes rumination, thought suppression, experiential avoidance, and impulsive or self-injurious behaviors. These actions provide temporary relief but often lead to long-term negative consequences.
The authors argue that using the term "emotion dysregulation" as a catch-all phrase obscures the distinct mechanisms at play. By breaking the construct into specific, measurable components, researchers can better understand how these processes interact and how they differ from other psychiatric conditions. Future research should prioritize studying these components simultaneously to map the dynamic, recursive nature of the disorder.
