Background: There is a wealth of evidence to suggest that the Borderline Personality Disorder (BPD, or similar Emotionally Unstable Personality Disorder, EUPD) construct is harmful. We provide a commentary on the ideas expressed in the May Debate issue, highlighting both concerns and alternatives. Method: We bring together lived experience, clinical and research expertise. This commentary was written collaboratively drawing on all these sources of evidence. Results: We outline evidence that the BPD construct is invalid, harmful, not necessary for effective treatment and a potential block to the development and evaluation of alternatives. Conclusions: We ask readers to consider these concerns, perspectives and ideas.
