Psychopathic traits predict the severity of post-traumatic stress in survivors of intimate partner abuse

Limited research exists exploring survivors' experiences in a relationship with a psychopathic abuser and their mental health following relationship dissolution. The present study examines the specific traits and patterns of abuse that have the most profound impact on survivors' mental health. Self-identified survivors of an intimate relationship with a psychopathic abuser (N = 454; M-age = 45.5) were recruited from intimate partner abuse support websites. They were assessed for abuse experiences, post-traumatic stress disorder (PTSD) symptomology, and the extent to which their abuser exhibited psychopathic traits via self-report questionnaires. Multiple regression analysis revealed that abusers' psychopathic traits were predictive of survivors' PTSD symptomology. Specifically, when controlling for the duration since last contact with the abuser and relationship length, interpersonal and affective traits, and experiences of versatile forms of abuse contributed to more severe PTSD symptoms. The present findings are consistent with an emerging body of research showing that abusers' emotional disconnection and predatory nature facilitate their ability to maintain an intimate relationship while engaging in a wide range of abuse resulting in widespread harm to survivors' mental health.
