You must meet 5 out of 9 criteria to be diagnosed with Borderline Personality Disorder (this is from DSM-IV):
- Frantic efforts to avoid real or imagined abandonment. Note: Do not include suicidal or self-mutilating behavior covered in.
- A pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation. This is called “splitting.”
- Identity disturbance: markedly and persistently unstable self-image or sense of self.
- Impulsivity in at least two areas that are potentially self-damaging (e.g., spending, sex, substance abuse, reckless driving, binge eating). Note: Do not include suicidal or self-mutilating behavior covered in.
- Recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior.
- Affective instability due to a marked reactivity of mood (e.g., intense episodic dysphoria, irritability, or anxiety usually lasting a few hours and only rarely more than a few days).
- Chronic feelings of emptiness.
- Inappropriate, intense anger or difficulty controlling anger (e.g., frequent displays of temper, constant anger, recurrent physical fights).
- Transient, stress-related paranoid ideation or severe dissociative symptoms.
