If you're not yet familiar with Dialectical Behavior Therapy (DBT) and are preparing for the social work licensing exam, now's the time to get comfortable with the basics. DBT was developed by Marsha Linehan to help people with Borderline Personality Disorder. Like CBT, DBT is rigorously rooted in research and results. Like CBT, DBT aims to help people with behavioral and cognitive regulation. What DBT adds is a focus on emotional regulation, distress tolerance, acceptance, and mindfulness.
DBT clients learn to use their "wise mind" (the just-right blend of emotion and reason) with the help of a series of acronyms (e.g., "DEAR MAN," and "ACCEPTS")--simple guides to a long list of coping skills. DBT has been shown to be helpful for clients with and without BPD. Given its research orientation, targeted symptoms, and apparent effectiveness, DBT is precisely the type of approach you can expect to see show up on the social work exam.
