DBT is suitable for people who are prone to overreacting to emotional situations. Such people have intense reactions to emotional situations affecting family, friendships, or romantic relationships. Their level of arousal in such situations is higher than that of the average person. Such people will benefit from therapy that focuses on the psychosocial approach to treatment.
DBT is also effective on people who have been diagnosed with borderline personality disorder. Such people have extreme mood swings and tend to be always dealing with a crisis. DBT can help them cope with the sudden rush of intense emotions. It enables them to negotiate situations in a way that maximizes their chances of achieving their goals without making unnecessary concessions.
