Which description best defines borderline personality disorder?

• A. A condition marked by extreme instability in mood, identity, and impulse control
• B. A pattern of excessive emotionality and attention seeking
• C. A grandiose sense of self-importance, a preoccupation with fantasies of success or power, and a need for constant attention or admiration
• D. A consistent discomfort and restraint in social situations, and extreme sensitivity to negative evaluation

Answer: (A)

Borderline personality disorder is defined by marked instability in affect, self-image, and behavior, which leads to impulsive actions and chaotic, intense relationships. The description that emphasizes extreme instability in mood, identity, and impulse control directly encapsulates these core features: rapid mood shifts, a fluctuating sense of self, and impulsive behaviors that can be risky or self-damaging. This pattern also commonly includes fears of abandonment and repeated crises, which stem from the overall instability you see across emotions, identity, and actions. The other descriptions fit different personality disorders: excessive emotionality and attention seeking align with histrionic personality disorder; a grandiose sense of self-importance with fantasies of power and a need for constant admiration fits narcissistic personality disorder; and consistent social discomfort with hypersensitivity to negative evaluation points to avoidant personality disorder.
