How many criteria must be met to diagnose Borderline Personality Disorder in DSM-5?

• A. Five of the seven criteria.
• B. All nine criteria.
• C. Four or more of the nine criteria.
• D. Five or more of the nine criteria.

Answer: (D)

The diagnostic threshold for Borderline Personality Disorder is a pattern that shows up across several areas, not just one symptom. In DSM-5, you need at least five out of nine specific criteria to meet the diagnosis, and these symptoms must be pervasive and cause clear impairment or distress in multiple settings. The nine criteria cover things like fear of abandonment, unstable relationships with cycles of idealization and devaluation, identity disturbance, impulsivity in self-damaging ways, recurrent self-harm or suicidal behavior, mood instability, chronic emptiness, intense anger, and transient paranoid or dissociative symptoms under stress. Because you don’t have to have all nine, five or more captures the characteristic instability without requiring every possible symptom to be present. This is why the correct choice emphasizes “five or more of the nine” rather than “all nine” or a different number.
