Dialectical behavior therapy (DBT) is treatment that was orginally used to treat borderline personality disorder, but is now used to treat a number of mental health disorders. It is a cognitive-behavioral approach that emphasizes the psychosocial aspects of treatment. The theory behind the approach is that some people are prone to react in a more intense and out-of-the-ordinary manner toward certain emotional situations, primarily those found in romantic, family and friend relationships. DBT theory suggests that some people’s arousal levels in such situations can increase far more quickly than the average person’s, attain a higher level of emotional stimulation, and take a significant amount of time to return to baseline arousal levels.
People who are sometimes diagnosed with borderline personality disorder experience extreme swings in their emotions, see the world in black-and-white shades, and seem to always be jumping from one crisis to another. Because few people understand such reactions — most of all their own family and a childhood that emphasized invalidation — they don’t have any methods for coping with these sudden, intense surges of emotion. DBT is a method for teaching skills that will help in this task.
