DBT is an approach widely used to help clients learn to manage intense emotions and improve relationships by learning specific skills to be practiced in and outside of sessions. Skills taught in DBT sessions are derived from four key areas: Mindfulness, Distress Tolerance, Emotion Regulation, and Interpersonal Effectiveness. These can be summarized as follows:
Mindfulness -- learning to be fully present and to accept the current moment
Distress Tolerance -- rather than trying to push away or escape from a difficult emotion, one learns to tolerate its presence
Emotion Regulation -- learning ways to manage and alter intense emotions which often cause problems in one's life
Interpersonal Effectiveness -- learning techniques to improve how one assertively communicates with respect towards self and others
I have found DBT to be a very useful component to therapy when someone is seeking to improve the way they manage their emotions, to decrease interpersonal conflict, and to learn to more easily tolerate difficult times in their lives.
Please note: I use aspects of DBT skill-building in my practice which can be applied to many emotional struggles in people's lives. If you are searching for a Certified DBT provider and/or one who follows Marsha Linehan's full treatment model, I would recommend that you find a therapist who has built their practice around DBT and provides individual, group, and between-session phone consults as outlined by Linehan.
