Core Evidence

There is a wealth of evidence supporting the effectiveness of DBT. The first randomized controlled trial (RCT) of DBT was published in 1991, in which Dr. Marsha Linehan and her colleagues found that DBT resulted in significant improvements for chronically suicidal and self-injuring women with borderline personality disorder, a clinical population that had previously been viewed as untreatable (Linehan et al., 1991).

In the decades since this landmark study, DBT has been extensively researched for individuals with a wide range of mental health conditions receiving treatment in diverse practice settings around the world.
