According to the DSM-V (American Psychiatric Association, 2013), “the essential feature of borderline personality disorder is a pervasive pattern of instability of interpersonal relationships, self-image, and affects” (p.663). To meet the diagnostic criteria for borderline personality disorder (BPD) a person must have at least 5 of the following 9 symptoms:
- Frantic efforts to avoid real or imagined abandonment.
- Unstable and intense interpersonal relationships characterised by alternating between extremes of idealisation and devaluation.
- Identity disturbance: unstable self-image or sense of self.
- Impulsivity in at least two areas that are potentially self-damaging (e.g. spending, sex, substance misuse, reckless driving, binge eating).
- Recurrent suicidal behaviour or threats, or self-mutilating behaviour.
- Instability of mood and marked reactivity of mood.
- Chronic feelings of emptiness.
- Inappropriate, intense anger or difficulty controlling anger.
- Transient, stress-related paranoid ideation or severe dissociative symptoms.
