A client with borderline personality disorder has a history of childhood trauma. Which of the following is a risk factor?

• A. History of childhood trauma
• B. Anxiety disorder
• C. Recent concussion
• D. Recent travel

Answer: (A)

Childhood trauma is a major risk factor for borderline personality disorder because early abusive or neglectful experiences disrupt the development of secure attachments and healthy emotion regulation. This sets the stage for lasting instability in mood, self-image, and relationships, which are central features of BPD. While anxiety disorders can co-occur, they do not by themselves increase the risk of developing BPD in the same way early trauma does. A recent concussion is a physical injury with no established link to causing BPD, and recent travel has no relevance to BPD risk. Thus, history of childhood trauma best explains the risk factor in this scenario.
