Dialectical Behavior Therapy (DBT) is a cognitive behavioral treatment that was originally developed to treat chronically suicidal individuals diagnosed with borderline personality disorder (BPD) and it is now recognized as the gold standard psychological treatment for this population. In addition, research has shown that it is effective in treating a wide range of other disorders such as substance dependence, depression, post-traumatic stress disorder (PTSD), and eating disorders.
The client is miserable and their behavior is out of control: they may be trying to kill themselves, self-harming, using drugs and alcohol, and/or engaging in other types of self-destructive behaviors. When clients first start DBT treatment, they often describe their experience of their mental illness as “being in hell.” The goal of Stage 1 is for the client to move from being out of control to achieving behavioral control.
In Stage 2, they’re living a life of quiet desperation: their behavior is under control but they continue to suffer, often due to past trauma and invalidation. Their emotional experience is inhibited. The goal of Stage 2 is to help the client move from a state of quiet desperation to one of full emotional experiencing. This is the stage in which post-traumatic stress disorder (PTSD) would be treated.
In Stage 3, the challenge is to learn to live: to define life goals, build self-respect, and find peace and happiness. The goal is that the client leads a life of ordinary happiness and unhappiness.
For some people, a fourth stage is needed: finding a deeper meaning through a spiritual existence. Linehan has posited a Stage 4 specifically for those clients for whom a life of ordinary happiness and unhappiness fails to meet a further goal of spiritual fulfillment or a sense of connectedness of a greater whole. In this stage, the goal of treatment is for the client to move from a sense of incompleteness towards a life that involves an ongoing capacity for experiences of joy and freedom
