Dialectical behaviour therapy in the treatment of borderline personality disorder: a commentary.

Why you should read this article: • To refresh your knowledge of what dialectical behaviour therapy (DBT) entails and its potential benefits • To learn about the strength of the evidence reported by a meta-analysis that investigated the effects of DBT for patients with borderline personality disorder • To understand the importance of critical thinking when reviewing the evidence on the effects of psychotherapeutic interventions and how these relate to practice. Dialectical behaviour therapy (DBT) is a psychotherapeutic intervention that was designed specifically to treat deliberate self-harm (with or without suicide intent) in women with borderline personality disorder (BPD). DBT has received the most research attention compared with other psychological approaches used in the management of symptoms of BPD. This article provides a commentary on a meta-analysis of 11 randomised controlled trials (RCTs) that investigated the effects of DBT on self-harming behaviours and negative emotions in patients with BPD. The commentary includes a critical appraisal of the methodology used in the meta-analysis. The authors of this article conclude that although the meta-analysis provides some evidence that DBT may reduce self-harming behaviours and depression in individuals with BPD, its methodological limitations, and the high risk of bias identified within the RCTs reviewed, mean that the results should be viewed with caution.
