Clinical efficacy of a combined acceptance and commitment therapy, dialectical behavioural therapy, and functional analytic psychotherapy intervention in patients with borderline personality disorder.

Brief adaptations of acceptance and commitment therapy and dialectical behavioural therapy are effective interventions for BPD patients, in combined or isolated modalities, and with or without the inclusion of functional analytic psychotherapy. The reduction of experiential avoidance and the acquisition of mindfulness skills are related with the diminution of BPD symptoms severity, including emotional dysregulation and negative interpersonal attachment.
