Self-injurious behavior is most commonly associated with which personality disorder?

Self-injurious behavior is most commonly associated with borderline personality disorder (BPD) due to the emotional dysregulation and intense interpersonal struggles characteristic of this condition. Individuals with BPD often experience overwhelming emotions and distress, leading them to engage in self-harm as a maladaptive coping mechanism to express their pain, avoid emotional numbness, or communicate their distress to others.

This behavior can also reflect feelings of emptiness and identity disturbance that frequently accompany BPD. The impulsive nature of the disorder makes self-injury more likely as an immediate response to emotional pain or relationship issues. Understanding this connection is crucial for effective assessment and intervention strategies in treating individuals with BPD.

The other personality disorders listed do not typically exhibit self-injurious behavior as a primary symptom, making them less relevant in this context.
