Dialectical behavior therapy is a type of therapy that helps teens learn how to manage their emotions, deal with difficult situations, and develop healthier coping skills. DBT exists on the belief that two opposing thoughts or ideas can exist at the same time, and both be true. By coming to terms with this, adolescents learn to accept themselves for who they are while also changing their behavior. DBT was originally developed to help treat people with borderline personality disorder (BPD), but it has since been shown to be effective for treating a variety of adolescent mental health disorders, including substance abuse.
