Dialectical behavior therapy (DBT) is a modified version of cognitive behavioral therapy (CBT), developed in late 1980s by Marsha M. Linehan. This modality works towards helping people increase their emotional and cognitive regulation by learning about the triggers that lead to reactive states and helping to assess which coping skills to apply in the sequence of events, thoughts, feelings, and behaviors to help avoid undesired reactions.Dialectical behavior therapy (DBT) is now used in a variety of psychological treatments including treatment for addiction and many different types mood disorders including depression and anxiety. Research indicates that Dialectical behavior therapy (DBT) might have some effect on patients who present varied symptoms and behaviors associated with spectrum mood disorders, such as individuals who struggle with bipolar disorder and trauma. DBT combines cognitive behavioral techniques for emotion regulation and reality-testing with concepts of distress tolerance, acceptance, and mindful awareness largely derived from Buddhist meditative practice.
