DBT was created as an answer to the difficulties clients with Borderline personalities had with feeling invalidated by the CBT approach.  It has grown to become the most widely used treatment modality for anyone struggling with regulating their emotions. 

This approach teaches skills to tolerate stressors, practices to increase emotional regulation and to increase satisfaction in interpersonal relationships with others.  It is an intensive and structured style of therapy that is incredibly effective when the skills are practiced regularly.
