Background: Those with cooccurring antisocial personality disorder (ASPD) and borderline personality disorder (BPD) are reported to be highly psychopathic and to represent a severe challenge to treatment efforts. In a sample of such individuals, the effects of two treatments, mentalization-based therapy (MBT) and the unified protocol (UP), were investigated on three outcomes: (i) the psychopathy trait domains of meanness, boldness and disinhibition proposed by the triarchic psychopathy model (TPM); (ii) antisocial and borderline symptom severity; and (iii) the severity of their common features including impulsivity, anger expression and self-harm.

Methods: Of 163 individuals with BPD + ASPD screened for eligibility, 55 were randomized to MBT treatment and 53 to UP treatment.
