A pervasive pattern of instability of interpersonal relationships, self-image, and affects, and marked impulsivity beginning by early adulthood and present in a variety of contexts, as indicated by five (or more) of the following:

  1. frantic efforts to avoid real or imagined abandonment. Note: Do not include suicidal or self-mutilating behavior covered in Criterion 5.
  2. a pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation
  3. identity disturbance: markedly and persistently unstable self-image or sense of self
  4. 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 Criterion 5.
  5. recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior

  7. chronic feelings of emptiness
  8. inappropriate, intense anger or difficulty controlling anger (e.g., frequent displays of temper, constant anger, recurrent physical fights)
