The main goal of DBT is to build a life worth living. This therapy combines dialectics and behaviorism to support clients. The concept of dialectics is that two supposedly opposing things can be true simultaneously. One of the most common dialectics in DBT is balancing acceptance and change. For example, the idea that you are currently doing the best you can and you can also do better. In DBT, therapists and clients are in an equal relationship and work together as a team to make therapy effective.

DBT helps people understand how emotion dysregulation is present in various areas of their lives, such as self-concept, relationships, and health. Common behavior targets in DBT are suicidal ideation and behaviors, self-harm, substance use, disordered eating, and high-risk or dangerous behaviors. DBT is also an evidence-based treatment for individuals with borderline personality disorder.
