Borderline Personality Characteristics: A Betrayal Trauma Approach

Borderline Personality Disorder (BPD) has been associated with both trauma and insecure attachment styles. Betrayal Trauma Theory proposes survivors of interpersonal trauma may remain unaware of betrayal in order to maintain a necessary attachment. This preliminary study reports on the relations between self-reports of betrayal trauma experiences and borderline personality characteristics in a college sample. Using multiple regression, betrayal was significantly associated with BPD characteristics. High-betrayal trauma was the largest contributor to borderline traits and medium-betrayal trauma was also a significant predictor. However, traumas of low betrayal were not associated with BPD features. These results stand even after controlling for gender. These findings suggest betrayal may be a key, and yet heretofore unaddressed, feature of borderline personality disorder.
