Which of the following disorders is characterized by impulsivity and instability in self-image?

Borderline Personality Disorder (BPD) is characterized by pervasive patterns of impulsivity, emotional instability, and a notably unstable self-image. Individuals with BPD often experience intense emotional responses and have considerable difficulty managing their feelings, which can lead to impulsive decision-making and unstable relationships. The instability in self-image often results in significant fluctuations in self-esteem, leading individuals to view themselves in dramatically different ways throughout different periods.

This disorder also commonly presents with symptoms such as fear of abandonment, chaotic interpersonal relationships, and self-destructive behaviors, further emphasizing the challenges associated with maintaining a consistent sense of identity. The impulsivity can manifest in various ways, such as reckless spending, substance abuse, or risky sexual behavior, all of which are often attempts to cope with emotional distress or to fill an internal void.

The other disorders listed, while they share some characteristics with impulsivity or instability, do not encompass the same degree of emotional dysregulation and self-image variation specific to Borderline Personality Disorder.
